Plate, base and column of a radial drilling machine

Foundation slab 1 is a rigid casting, reinforced with ribs in the longitudinal and transverse directions. On the surface of the plate there are T-shaped grooves that serve for fastening a table, workpieces or special devices.

A base 5 is fixedly mounted on the plate, in which a column 6 is installed on bearings 3 and 10. The column is the most loaded part of the machine, therefore it is made of a steel pipe and has a hardened working surface with a slight roughness, along which the sleeve moves.

Purpose of the unit

All equipment of this type is designed to work with large workpieces, whose free movement on the table is impossible or takes a lot of time.

If we delve even deeper into the information about the operation of the machine, it is easy to find out that it is used to produce a large or small number of parts, especially those of the same size range. This feature makes it easy to complete standard orders in a short time.

It is easy to perform the following types of work on the equipment:

drilling;
countersinking process;
reaming;
deployment;
thread cutting.

There is a variation of this machine, it is called a radial drilling machine 2K52-1. The difference between these two units is the landing and secondary connecting bases. The location of these parts allows you to expand the range of use of the machine in the production of small-sized parts.

Radial drilling machines

What distinguishes radial drilling machines from vertical drilling machines is the design possibility of aligning the axis of the workpiece hole with the axis of the spindle by moving the spindle relative to the stationary workpiece to any location on the horizontal surface of the table. By design, radial drilling machines are divided into general-purpose machines, portable - for processing holes in large-sized workpieces (the machines are carried by a crane to the workpiece and machine vertical, horizontal and inclined holes) and self-propelled, mounted on trolleys with their fastening at the processing site with using shoes.

Radial drilling machine mod. 2554 (Fig. 7) is used when machining holes in medium-sized body parts. The machine allows you to perform drilling in solid material, reaming, countersinking, reaming and boring holes, tapping and other operations. On the foundation plate 1 of the machine there is a pedestal 2 with a fixed column 3, on which a sleeve 4 is mounted. The sleeve rotates around the column, ensuring the processing of holes anywhere in the part without moving it. A traverse 6 is mounted on the sleeve, which has horizontal guides along which the spindle head 5 can move. Inside the spindle head there is a gearbox, a gearbox and a spindle assembly 7. The controls are located on the front cover. The workpieces to be processed are installed on a side table or directly on the upper plane of the foundation slab 1.

Rice. 6.

Radial drilling machine mod. 2554: 1 - plate; 2 - cabinet; 3 - column; 4— sleeve; 5— spindle head; 6 — traverse; 7— spindle

The spindle 7 with the drilling head can move vertically along the guides of the sleeve 4, in the radial direction along the traverse 6, and also, together with the traverse 6 and sleeve 4, rotate around the axis of the fixed column 3. These three movements allow you to install the tool in any coordinates. The spindle is reversed using a friction clutch. The traverse 6 mechanically moves vertically along the sleeve 4 with automatic release at the beginning and clamping at the end of the stroke.

The drilling head is equipped with an automatic feed shutdown mechanism, which is triggered when the required drilling depth is reached. The machine is equipped with a system of safety devices that eliminate the possibility of its breakdown due to overloads.

Features of the design of machine components

Desktop

The base plate is made as a modified cast iron casting. For reinforcement, the structure is provided with longitudinal and transverse ribs. Special T-shaped grooves allow the use of different methods of fixing workpieces. You can install:

Three-jaw chucks, cylindrical parts are fixed in them. Then axial drilling will be performed with high precision.
Four-jaw chucks are designed for fixing asymmetrical parts on the table.
Pneumatic or eccentric clamps are used for positional fastening of a special shape.

Support column

A conical ring is used to fix the column. During axial movement, the cone clamps the cylinder, preventing it from rotating in the sleeve. Involuntary rotation of the column is impossible. It is firmly fixed.

To facilitate the movement of the cone ring, special flanges are used. To displace them, screw clamps are used, connected by control handles and corresponding longitudinal movement mechanisms.

Drive unit

The main mechanism for ensuring rotation speed, its switching during drilling and the operation of the gearbox is characterized by one feature. Having disassembled the gearbox of the 2K52 drilling machine, the passport of which includes its own electric drive, we can say that there are several similar mechanisms.

It is allowed to install 3 electric motors in accordance with the operating manual 2K52 and other regulatory documents. The power of the main drive is 1.5 kW.

The manual indicates the weight of the installation - 1250 kg, and also displays a full explanation of the name of the machine.

The kinematic scheme is based on four chains, the first of which is the rotation chain of the main spindle. When disassembling the installation, you can notice that the load when the spindle rotates is evenly distributed over the gearbox and U-type drive shaft.

Kinematic diagram of the 2K52 machine

The components of the kinetic scheme are also:

Feed chain.
Chain of vertical displacement of the main sleeve.
Column clamping circuit.

During the assembly process, the designers equipped the 2K52 installation with the maximum set of additional modules. Expanded functionality allows you to increase the accuracy of all operations, it also becomes possible to work with complex workpieces, and productivity is accelerated.

As a result, the 2K52 drilling machine has parameters suitable for performing many jobs, the adjustment of which allows one to achieve fairly high accuracy. Each work operation is carried out without complex manipulations, which can be performed even by a worker with minimal qualifications. The resulting holes always have the correct shape.

2K52 portable radial drilling machine. Purpose and scope

Radial drilling machines model 2K52 were produced until 1990, then significant changes were made to the kinematic diagram of the machine. In particular, the number of teeth in almost all gears was changed, which led to the appearance of a machine with the index 2K522.

The portable radial drilling machine model 2K52 is designed for processing holes in medium and large parts in single, small-scale and mass production.

On the 2K52 drilling machine you can perform: drilling, reaming, countersinking, reaming, threading and boring holes. It can be used most effectively when processing holes located at angles in different planes of large parts in tool, repair, experimental, assembly and production shops.

Operating principle and design features of the machine

The 2K52 machine consists of the following main components: base, column, body, sleeve, carriage, drilling head, column clamping mechanism, coolant supply system and electrical equipment.

A column with a body and a sleeve is installed on the base, and a coolant tank is attached to it at the end.

The column is a steel pipe installed in a plinth on two bearings. The base contains part of the electrical equipment and the column clamping mechanism.

The housing is a cast iron casting of rigid shape and is the base part for assembling the gearbox, the mechanism for moving the housing along the column, and the mechanism for clamping the housing on the column.

Electrical equipment is installed in the housing niche.

On the front side of the case there are control handles for the gearbox, a mechanism for moving the barrel along the column and a control panel.

The sleeve is attached to the body with four clamps. A carriage with a drilling head attached to it moves along the guides of the sleeve. The sleeve is rotated around its axis by a handle through a worm gear.

The drilling head is a cast iron casting in which the spindle, feed box and steering device are mounted.

The machine spindle has a wide range of rotation speed control and can be spatially oriented by rotating the sleeve and drilling head.

The machine is equipped with a device for processing holes to a given depth and devices that protect against overloads in terms of torque and axial force. When processing large parts outside the working surface of the plate, the machine is aligned using screw supports. It is recommended to process small parts on a box-shaped table mounted on the table plate.

A distinctive feature of the machine of this standard size is the presence of a rotating column and mounting of the drill head carriage on sleeve guides on rolling bearings, which significantly increases the ease of operation of the machine.

The machine is manufactured for operation in temperate climates, on request for operation in tropical climates, as well as for processing parts in the inch measurement system.

The electrical equipment of the machine can be designed for supply current with a frequency of 50 and 60 Hz and a voltage of 220, 380, 400, 415, 440, 600 V.

On request, the machine is equipped with an electromechanical column clamp, as well as with a system for supplying coolant to the cutting zone.

Machine accuracy class N according to GOST 8-77.

The roughness of the treated surfaces, depending on the work performed, is R = 80-20 microns.

How does the machine work?

Here are the main details of the machine:

base;
Column;
frame;
barrel sleeve;
drilling head;
electrical equipment;
carriage.

Machine carriage
The body and sleeve are attached to the base, and a container for cooling liquid is attached to the end part.

The column is a large steel pipe, which is installed in the base and attached with two bearings. Electrical equipment and clamping mechanisms are also located there; it is worth knowing that clamps are not included with the original equipment, they must be ordered separately.

A densely shaped cast iron is the housing, which is the main part for the gearbox. It also has space for electrical equipment.

The sleeve is attached to the body part by means of four clamps. In the direction of this part, a carriage moves along with a drilling head.

The head itself consists of a spindle, a control device and a feed box.

The spindle is made of cast iron. Has a large range for drilling frequency.

Drill head

In the manufacture of the body, cast iron was used, which is resistant to vibration loads and is not susceptible to high humidity. Inside there is a system for switching spindle rotation or feed speeds. To significantly extend the service life of the structure, the contacting elements are lubricated with a special suspension. To do this, a lubrication pump, main motion drive or spindle brake are installed on the housing.

The gearbox is controlled through externally mounted handles. In the manufacture of gears, alloy steel is used, which has increased wear resistance.

Tantalum capacitors K52-1, K52-2

Capacitors K52-1, K52-2 are tantalum volumetric porous oxide electrolytic capacitors of constant capacity, accumulate charge from 1.5 µF to 470 µF at voltages from 3.2 V to 100 V.
The permissible deviation of the capacity is ±10%, ±20%, ±30%. Designed for use in DC or pulsating current circuits. Structurally sealed tantalum capacitors are produced in metal cylindrical (K52-1) or cup (K52-2) cases with flexible axial-type wire leads.

Capacitors have a polar type of design. An aqueous 35-38% solution of sulfuric acid is used as a working electrolyte.

Failure of an electrolytic capacitor is often accompanied by a characteristic explosion and possible release of liquid electrolyte, so you should pay special attention to the polarity of the capacitor when installing it in the circuit

On the side surface of the body of the volumetric-porous tantalum storage device there is a nominal marking indicating the capacity, permissible deviation, operating voltage and polarity of the terminals.

In the absence of polarity markings, the anode terminal of the K52-1 capacitor is determined by an end that is filled with epoxy resin, and the anode terminal of the K52-2 capacitor is determined by a welding unit (connection of a tantalum wire terminal and a tinned nickel terminal) or an end made of an insulating plug.

Installation of capacitors - at the terminals using soldering. Installation in a vertical position with the negative terminal down is allowed. When bending leads, the minimum distance from the capacitor body or lead welding unit is 2.5 mm, the height from the body to the soldering point is at least 5 mm, and the bending radius is at least one and a half diameter of the lead.

The elevated operating temperature of the environment is no more than +155°C, the reduced operating temperature is not lower than -60°C. Loss tangent tgδ from 5% to 30%, maximum leakage current – 30 µA. The operating time is at least 5000 hours.

Tantalum capacitors K52-1, K52-2 are resistant to vibration loads with a frequency of 1-5000 Hz with acceleration up to 20g and mechanical shocks of a single (acceleration up to 1000g) or multiple (acceleration up to 150g) action.

Tantalum oxide electrolytic capacitors K52-1, K52-2 are used in household, medical equipment, railway transport and other electronic equipment.

Detailed characteristics, labeling, overall and installation dimensions of tantalum capacitors K52-1, K52-2 are indicated below. Our company guarantees the quality and performance of capacitors for 2 years from the date of purchase; quality certificates are provided.

The lightweight radial drilling machine 2L53U is used for single, small-scale and mass production. The equipment is actively used in small procurement enterprises, workshops and factories. The mechanism is capable of performing such technological operations as:

countersinking;
drilling;
reaming;
thread cutting;
deployment;
cutting planes with a cutter.

Before purchasing a 2L53U machine, it is worth preparing a concrete base for installing the equipment. The layer height must be at least 40 cm.

Main parts and components of the machine:

cast iron work table with a rotating design that can be rotated around its axis by +90 and -80 degrees manually;
coolant supply system;
feed switching device;
a drilling head, in the body of which there is a gearbox and a feedbox, a device for switching the feed and controls;
electrical equipment, wiring and electrical cabinet;
a barrel on which a rotary table is mounted, which moves vertically and around the column 360 degrees;
controls;
mechanism for moving and clamping the drill head.
a sleeve on which the drill head mechanism is located;
a foundation slab on which a vertical cast iron column is located.

To prevent breakage of electrical wires, the rotation of the hose relative to the column is constrained by rigid stops. The movement of the barrel along the column is possible due to the reliable connection of the screw with the bracket. To prevent overheating of the working tool and rapid wear of the equipment, a coolant is built into the 2L53U design, which supplies liquid using a cooling pump.

To switch the speed and feed, the operator needs to operate the handle, which is located on the right side of the drill head. The safety clutch is located in such a way that a specialist can make the necessary adjustments without dismantling the components.

The industrial machine tool 2L53U is equipped with three electric motors, namely:

for supplying coolant to the working area - 0.125 kW;
table drive – 0.56 kW;
spindle drive – 2.2 kW.

The 2L53U machine is reliably protected from overloads and short circuits using a fuse and a thermal relay. Unauthorized movement of the table is not allowed if the spin handle and limit switch are locked. In addition, there is a special braking device, which is controlled by an electromagnet. In order for the spring brake to work, the handle must be set to the neutral position, which automatically turns off the electromagnet. The braking system also operates automatically in the event of intentional or accidental power outages.

The 2L53U radial drilling machine allows the operator to perform processing of various levels of complexity. This is possible due to the wide range of spindle speeds and feeds. The big advantage is that the specialist, working at the machine, makes a minimum of physical effort with smaller drilling radii, which allows increasing the efficiency of the work process. All types of technological operations are carried out strictly with international quality standards.

To improve the mechanism, the following is mounted into the structure:

protective screen for the drilling and cutting area;
air cooling system for working equipment;
swivel or standard cabinet.

This machine model is considered indispensable if the enterprise constantly needs to process metal parts. The equipment is quite easy to use and can easily act as an independent production unit.

Unit differences

Mechanical components are used to brake and stop the spindle head.

The machine is easy to use, despite its apparent complexity. Before starting work, you should read the instructions for use.

2N55 radial drilling machine. Purpose and scope

The radial drilling machine model 2N55 replaced the outdated model of the machine of the same series 2A55.

The machine is designed for drilling holes in steel with a diameter of up to 50 mm using drills of medium hardness (tensile strength σ = 55..65 kg/mm²).

The 2N55 radial drilling machine is designed for drilling, reaming, countersinking, reaming, boring holes, tapping threads, trimming ends with a cutter, as well as performing other similar operations when processing various body parts in machine shops of single, small-scale and mass production, as well as in assembly shops of heavy transport engineering factories. When equipped with fixtures and special tools, the machine can be used for high-performance processing of large parts in large-scale production.

The 2N55 radial drilling machine has a two-column layout of the machine part, which makes it possible to create a rigid unit structure that does not allow the spindle axis to shift when clamping the column. A special center-type column clamp creates a braking torque that guarantees high-performance drilling.

To rotate the column, little force is required at the smallest drilling radius, which also ensures high productivity and reduces operator fatigue. A wide range of spindle speeds and feeds ensures highly productive work with any combination of processed materials, tool sizes, etc.

Spindle balancing is ensured by a special counterweight, allowing convenient adjustment from the workplace if the tool weight changes.

The cutting modes allowed on the machine are determined by the dynamic parameters of the machine:

Effective power on the spindle, kW - 4.0
Maximum torque on the spindle kg*cm - 7100
Maximum feed force, kgf - 2000

It should be borne in mind that the greatest power on the spindle can be used starting from the 7th speed level (80 rpm, see the section of the passport “Main motion mechanics”).

Low spindle speeds are used on a machine tool to perform operations that require less power but more torque. Therefore, in the first six speed steps, the power on the spindle does not reach its maximum effective value.

The maximum permissible feed force is determined by the strength of the machine parts and the rigidity of its structure. Exceeding the permissible value of the feed force causes the feed mechanism's safety clutch to turn off. Therefore, the mechanical feed amount should be selected so as not to exceed the permissible feed force. The feed force largely depends on the correct sharpening of the drill.

Wide ranges of spindle speeds and mechanical feeds allow you to increase machine productivity.

A preselective remote electro-hydraulic device allows you to change modes with their preliminary selection. The machine has an automatic shutdown mechanism when the specified drilling depth is reached.

The presence in the machine of preselective control of speeds and feeds, easy hydraulic control of the spindle friction, the ability to disconnect the spindle from the gearbox, the presence of reliable hydraulic clamps of the column and drilling head, working both together and separately, as well as the concentration of all controls on a small area of the drilling head allows you to minimize auxiliary time.

If you need to change tools frequently, it is recommended to use a quick-change chuck. A safety tap chuck should be used for cutting threads.

The machine has the following advantages compared to the previously produced model:

tightening of the clamping of the column due to the developed cone, which allows working at high cutting conditions; increasing the volume of the working space by increasing the strokes of the hose along the column and the head along the hose;
achieving the specified accuracy and achieving accuracy outside the slab thanks to the two-column layout and developed sleeve guides;
reduction of time for re-aligning the hose in height due to the increased speed of its movement and the fast action of the clamp;
increased maintainability thanks to a new design of column guides;
the absence of mechanisms at the upper end that require maintenance, which ensures ease of operation of the machine and improves its appearance.
