Kinematic diagram of the drilling machine 2Р135Ф2-1
Kinematic diagram of the drilling machine 2р135ф2-1 with CNC 2П32-3
The kinematic diagram of the machine (Fig. 4.6) consists of the following independent kinematic chains: main movement drive (rotation of the turret spindles); cross table feed drive; caliper drive with turret head; turning the turret head; pressing tools out of spindles.
Main movement chain
Main movement chain: two-speed asynchronous electric motor M1 (N = 4/4.5 kW; n = 1470/990 rpm) - 29/41 gear transmission - shaft I - shaft II (through gears 24/48 and 36/36 at engaged couplings M1 and M2 or through gear 14/36 with engaged coupling M3) - shaft III (via gears 14/36 and 48/24 with engaged couplings M4 and M5) - shaft V through bevel gear 21/21 - to one of turret spindles through 35/42 gears; 31/49; 49/47; 47/35.
Cross table feed drive chain
The feed drive chain of the cross table has two gearboxes, one of which moves the table along the slide (X-axis), and the second drives the movement of the slide along the frame (Y-axis).
Kinematic chain of the slide drive
The kinematic chain of the slide drive ensures their fast, medium and slow movements. Fast movement (at a speed of 7000 mm/min): M4 electric motor (N=0.6 kW; p=1380 rpm) - 16/40 gears; 34/22; 22/52; 52/34 - ball screw.
Moving at medium speed (200 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 38/42; 22/52; 52/34 - ball screw. Slow movement (at a speed of 50 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 16/64; 22/52; 52/34 - ball screw. A feedback sensor is mounted on the ball screw.
The table moves along the slide from the M5 electric motor (N = 0.6 kW; n = 1380 rpm); the kinematic chain of the drive of this movement is similar to the kinematic chain of the drive of the slide movement.
Turret Caliper Drive Chain
Caliper drive chain with turret head: DC electric motor M2 (N = l.3 kW; n = 50..2600 rpm) - 13/86 gear (or 37/37 gear - 4/25 worm gear - lead screw, equipped with a brake clutch (preventing arbitrary lowering of the caliper when the electric motor is turned off) and a remote control feedback sensor.
Turret rotation drive chain
Turret head rotation drive chain: M3 electric motor (N=0.7/0.9 kW; n= 1400..2700 rpm) - 23/57 gear - 1/28 worm gear - 16/58 gear - turret body .
Pressing tools out of spindles
Pressing tools out of spindles: M3 electric motor - 18/52 gear (with the clutch engaged) - 1/28 worm gear - 21/21 gear - eccentric mounted in the groove of the turret head rotation axis and pressing tool.
Lubricating the turret support
Lubrication of the turret head support is carried out forcibly according to the following scheme: MZ electric motor - 18/52 gears; 52/75 - EZ eccentric, driving the plunger pump.
Gearbox lubrication
The gearbox is lubricated by a gear pump driven by the gearbox electric motor through a V-belt. The oil supplied by the pump enters the distribution chamber, where it is distributed to lubricate all moving parts of the gearbox and electromagnetic clutches, and then drained into the reservoir. The oil level is controlled by an oil indicator.
Lubrication of caliper feed gearboxes and cross table
Lubrication of the caliper feed gearboxes and the cross table is carried out by spraying oil onto the gears. The oil level is monitored visually using oil indicators.
Lubricating the guides and screw pairs of the cross table
The guides and screw pairs of the cross table are lubricated manually using a lubricator. The bearings of the turret spindles are lubricated with grease.
Coolant supply
The coolant is supplied from a centrifugal pump. To cool the tool in the cutting zone, an individual drive is provided, which allows you to direct a stream of coolant to the desired location. The supply of coolant in the automatic cycle begins when the caliper moves down (the beginning of the working feed) and stops when the caliper begins to return to its original position (in this case, the corresponding toggle switch must be turned on on the control panel).
Electrical equipment of the machine
The electrical equipment of the machine consists of a separate cabinet of relay automation and CNC, as well as elements installed directly on the machine. Electrical connections between the machine components and the CNC are made by harnesses in metal hoses ending with connectors.
The electrical circuit of the machine provides the following operating modes:
- commissioning;
- semi-automatic with task input from CNC switches;
- semi-automatic with task input from punched tape;
- automatic with task input from punched tape.
The mode is selected using switches located on the control panels of the machine and the CNC.

- semi-automatic (positioning of the table according to the program from the DRO device, and the approach and removal of the quill with the spindle manually).
To establish the adjustment mode, it is necessary to set the “Mode selection” switch on the machine control panel to the “Adjustment” position.
Working on the machine in the “Adjustment” mode is carried out by pressing the corresponding buttons on the control panel.
To select the movement axis, use the “Select X and Y axes” switch. To move the table in positive and negative directions, use the “Positive direction of movement” buttons, respectively. To control the direction of spindle rotation, use the “Spindle rotation to the left” buttons on the control panel.
To rotate the gears in the gearbox when switching spindle rotation speeds, use the “Spindle Rotation” button.
The 2S132TS machine provides the following control modes:
- manual mode;
- auto.
In manual mode, set the “Mode selection” switch to the middle position “Manual mode”. The machine is controlled by pressing the corresponding buttons on the machine console “Spindle rotation to the left”, “Stop”. The working feed is carried out both from the steering wheel and using a mechanical transmission from the main movement electric motor.
In automatic mode, set the “Mode selection” switch to the extreme left position “Drilling”. Set the cams depending on the processing depth. Using the steering wheel, move the spindle to the upper starting position. Press the “Start cycle” button.
Automatic thread cutting
ATTENTION! Thread cutting with an automatic spindle feed cycle is possible only for machines 2S132PFI and 2S132Ts. Feed ranges are shown in table
10.
During the automatic thread cutting cycle, set the “Mode selection” switch to the extreme right position “Thread cutting”. Set the cams depending on the processing depth. Press the “Start cycle” button. The end of thread cutting on the 2S132Ts machine is controlled by the corresponding cams on the dial, and on the 2S132PF2Y machine according to a given program.
The following modes are provided on the 2S132K and 2S132 machines:
- manual spindle feed;
- mechanical spindle feed.
Set the cams depending on the processing depth.
After turning on the rotation and feed of the spindle, processing of the part begins. When the desired machining depth is reached, the spindle feed will stop and the spindle will continue to rotate. To stop it, you need to press the “Stop” button.
When cutting threads on a machine with spindle reverse at a certain depth, set the dial on the drilling head so that the number corresponding to the processing depth is opposite the pointer. Align the cam mark “P” with the corresponding mark on the dial and secure the cam. Turn off mechanical feed. After turning on the spindle, manually insert the tap into the hole. After 2-3 spindle revolutions, there is no need for manual feed. When the specified cutting depth is reached, the spindle is automatically reversed and the tap exits the hole. In order for the spindle to rotate to the right, you need to press the corresponding button.
Vertical drilling machine mod. 2р135ф2
This Computer Numerical Control (CNC) machine is designed for drilling, countersinking, reaming, threading, face trimming, etc. in low to mid-volume production. The presence on the machine of a six-position turret for automatic change of cutting tools and a cross table with program control will create the ability to carry out coordinate processing of parts such as covers, flanges, panels and other parts without preliminary marking and without the use of jigs, machine accuracy class N.
Numerical control system. Machine mod. 2Р135Ф2 is equipped with a numerical control device “Coordinate S70-3”, which ensures simultaneous movement of the table along the X and Y axes when positioning the movement control along the axis (from the coordinate), makes it possible to control the rotation of the turret, select the value of the working feed and spindle speed. The device has a digital display and allows for input of corrections for tool length.
The positional rectangular CNC system is closed; code converters are used as measuring devices. The positioning accuracy of the table and support is 0.05 mm, the discreteness of programming and digital display is 0.05 mm. Number of controlled coordinates: total - three; simultaneously - two.
A column is mounted on the base of the machine, along the rectangular vertical guides of which a support carrying a turret head moves. The gearbox and feed reducer are rigidly mounted on the column. The cross table has a base along which the slides carrying the table itself move in the transverse direction. The latter, in turn, can move in the longitudinal direction along the slide guides. The movement of the slide and table is carried out from the gearboxes.
Rotate the turret head. The head rotates using the following kinematic chain. From the MZ electric motor (0.7/09 kW, 1400/2700 rpm) through the shaft transmission to the shaft, from which the worm gear transmits the movement to the shaft and transmission, which rotates the turret head. The clutch must be engaged. Before turning the turret, it must be unlocked, since it is secured by spring-loaded caliper rods located in the grooves of the turret. When the shaft on which the worm sits rotates, it has the ability to move axially, so it turns out of the worm wheel and, moving down through the rack and pinion gear with the wheel and the module, turns the shaft with an eccentric, which will release the turret with a system of levers; at the same time, the second rack wheel moves the rack on the shaft and thereby disengages the wheel on the shaft. Thus, the turret head is released and the kinematic chain connecting the rotation drive to the turret spindle is broken. After this, the worm reaches a hard stop and begins to rotate the turret by means of a transmission, changing the tool (direct rotation).
Simultaneously with the rotation of the turret head through the transmission, the shaft and gear rotates a positional command device on the shaft, which stops the direct rotation of the turret head by reversing the electric motor, having previously reduced its rotation frequency to 1400 rpm. During reverse rotation, the turret reaches the hard stop of the caliper and stops; at the same time, the worm, turning out of the worm wheel, moves upward. The shaft rotates in the opposite direction, the gear engages with the turret spindle wheel. The head is fixed and the spindle begins to rotate. The choice of the operating sequence of the turret spindles is set on the console. There are six processing cycles in total.
The table moves from the M4 engine (0.6 kW, 1380 rpm). The table gearbox does not differ from the sled gearbox, therefore, its kinematic diagram does not indicate shafts and wheels.
Thread cutting. For cutting threads with a machine tap, chucks are used that can be installed in any position of the turret. When cutting threads, use a copier, a screw-nut in steps of 1.0; 1.25; 1.5; 1.75; 2.0; 3.0 mm, set of replaceable collets for fastening taps, adapter squares. The threading head has a mechanism for adjusting the operation of the head in the cycle forward (threading) - reverse (unscrewing the tap after cutting the thread). The full cycle of work with the support is provided by the electrical circuit of the machine. Rotation from the spindle is transmitted through a liner inserted into the spindle of the turret head, through a gear coupling to the driver, spline shaft and collet.

Operating principle
Operation of the machine in operating mode occurs according to the following principle. The workpiece to be processed must be installed and securely fixed on the working surface of the coordinate table. The spindle with the installed tool should be located in the lowest position. Using the worktable longitudinal displacement system, the spindle must be centered.
Then you need to make sure that the end of the part to be processed and the spindle are coaxially positioned. Based on the kinematic possibilities, in the high-speed gearbox we select the rotation speed suitable for processing. We turn on the vertical electric motor of the main drive.
After setting up the kinematic diagram, the tool head moves to the end of the workpiece, and the desired technological operation is performed.

Brief description of the components of the machine 2S132, 2S132K, 2S132Ts, 2S132PF2I
The machine column is a hollow box-shaped cast iron casting. A drilling head and a lifting table with three T-shaped slots, in which overhead cross tables are fixed, are manually moved along the dovetail column guides: mechanized - on a mod. 2S132PF2I, floating with manual control - on a machine mod. 2S132K. An electric pump is installed on the foundation slab, inside the column. The base plate serves as a reservoir for the coolant.
The drilling head is a box-shaped cast iron in which all the main assembly units of the machine are mounted: speed box, feed box, spindle, feed mechanism, spindle counterweight and speed and feed switching mechanism.
The feed mechanism is driven from the feed box and is designed to perform the following operations:
- Manual or automatic approach of a tool fixed in the spindle to the part;
- Manual feed advance;
- Manual or automatic spindle retraction upward;
- Manual feed used in thread cutting.
The overhead mechanized cross table is designed to move the workpiece installed in a fixture on the working surface of the table in the longitudinal (along the X axis) and transverse (along the Y axis) directions.
The mechanized cross table provides fast movements, positioning in specified coordinates, as well as working feed of the workpiece for easy straight-line milling.
The table contains drives for the longitudinal movement of the table along the slide guides, the transverse movement of the slide along the base guides, as well as the protection of the longitudinal and transverse guides.
The floating table is designed for processing parts using a copier or marking and consists of three main parts: a table, a slide and a base.
The table moves along the slide in the longitudinal direction on roller needle bearings. The slide together with the table moves transversely on the same roller needle bearings. Roller needle bearings make it easy to move and set the table into the desired position.
