Operation and repair

The operation of the device begins with its column, which performs the function of fixing it on the floor surface. The column is made of cast iron. The work table, which is attached to the column, moves together with the drilling head using a manual drive.

The movement occurs along the column itself. The plate, which plays the role of the base, has an internal cavity in which a special cooling liquid is located. A sump tank is also installed there. An electric pump system is attached to the upper part of the base plate, with the help of which, during operation of the machine, coolant is supplied to the workpieces.

The feed box is installed separately in a special housing located in the working head.

The second main technique for operating the 2n135 machine involves operating the feeder. It includes the following elements:

• 2 couplings, one of which is ratcheting, the other is overrunning;
• steering wheel for control;
• rack-and-pinion gear located on a horizontal shaft;
• worm-gear;
• limba having divisions.

Limba

Thanks to the feeder, the scheme of working with the machine implies a wide range of actions:

• switching off, switching on feed;
• cutting threads on the product itself using the manual feed method;
• spindle retraction upwards from the workpiece;
• bringing the processing tool to the product manually;
• performing advance feed manually.

The mechanism works as follows: the jaw clutch is driven by a rotating handwheel. The clutch then drives a gear, which is connected to a rack, which feeds the spindle.

All this is done manually. When the processing tool impacts the workpiece, the gear rotates. Movement occurs along the axis of the shaft until the moment when the cams of the coupling itself are opposite each other. At this moment the clutch turns 2000.

In cases where the machine was repaired, it is necessary to check its components. It is important to ensure that there are no traces of corrosion on the device. After repair work, the unit runs idle, and the cutting tool is not installed. During a test run, the operation of the device is checked against the data in its technical passport.

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 possibility , 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.

The unit frame is made in the form of a monolithic, massive, cast-iron structure. The position of the productive surface is carried out by the operator on the supporting column manually, by pressing the locking device and turning the steering wheel, which performs the function of adjusting the position of the spindle. To move the table surface, special guide grooves are made on the column.

The base plate is also cast iron. It has a hollow structure, inside of which there is a container for storing cooling liquid. There is also a settling tank for large metal contaminants and a filtration device. On the support column itself there is an electric pump with a power of 120 W, which is responsible for supplying the liquid. The coolant is supplied through a system of tubes of various diameters, which supply water directly to the drilling element.

The power unit of the machine is located on the top of the body. The spindle block and gearbox of the machine are located in the housing. The kinematic diagram of the equipment has a simple design solution, in which the power unit and the speed box are connected by a straight shaft. Mechanical speed adjustment is carried out using a handle located on the front side of the drilling head. Speed ​​adjustment is done manually. The box transmits spindle rotation speed at twelve frequencies.

The operating elements of the unit are lubricated using a plunger pump in automatic mode. The operator will only need to monitor the oil level using the sensor located on the front panel.

This model has a manual spindle feed system. This system includes:

• A steering wheel that performs an adjustment function.
• Worm-like transmission.
• Overrunning ratchet and dog clutch.
• Limba.
• Shaft, horizontal, with rack and pinion gear.
