The drilling process of the friction plate mainly has the following realization methods:

1. Use a drill template to drill through holes on a common bench drill, and then spot-face the holes manually on a common drill press. This method is basically the original processing method, with low production efficiency, poor precision, high labor intensity for workers, and serious pollution.

2. Punch through holes on a punch press, and then, as above, spot-face the holes by hand on a common drill press. Due to the axial tearing and extrusion during the punching process, stress concentration will be generated and the friction plate will burst when rotating at high speed, so there is a potential safety hazard. Pollution is very serious, and efficiency is also low, and, because each product all will have a set of die correspondingly, production cost height, production period are long.

3. It is processed by a special multi-axis drilling machine. This is an efficient production method, but each product must have a corresponding multi-spindle box, which is costly and not suitable for the production of multiple varieties and small batches; moreover, the height of dozens of drill bits in the multi-spindle drilling machine is difficult to obtain in the production process. The adjustment is consistent, which affects the product quality and takes a long time to change the product during the production process.

(3) Contents of the invention: the purpose of this utility model is to overcome the problems of low production efficiency, high cost and poor working environment in the prior art, and propose a kind of product suitable for different production scales of different materials, with high production efficiency and improved working environment. Special automatic drilling machine for clutch friction plate.

The specific scheme of the utility model is: the existing ordinary drilling machine is improved, it has a base, a Y-axis horizontal driving device is installed on the base, a mobile workbench is installed on it, a vertical bed is designed on one side of the base, a vertical bed The upper part of the body is equipped with a Z-axis up and down driving device, which drives and connects the drill arm. The main motor is installed on the drill arm, and the drill jacket and drill bit are connected to the main motor. Under the drill bit, it is connected to the vertical bed. There is a cantilever bracket, and the head end of the bracket is equipped with an automatic bracket set. The improvement is: a. A rotary head is installed on the table of the mobile workbench, and it is equipped with a locking device. A motor is installed under the table. It is driven and connected with the rotary chuck; b. There is a dust suction chamber installed under the drill jacket and the front end of the cantilever bracket, and a vacuum cleaner is connected with the dust suction chamber.

In the utility model, the X-axis moving mechanism of the worktable on the common drilling machine is omitted, and a rotary head and a drive motor are added. By controlling the motor, the positioning on the porous circle on the clutch friction plate is automatically realized. The utility model is suitable for hole processing of friction plates of different materials, has high production efficiency, and is suitable for various production scales, especially for the production of many varieties and small batches, which highlights its superiority; due to the addition of a dust suction device in the utility model, it greatly improves the working environment of the workers.

(5) Specific implementation methods:

Referring to accompanying drawing, the utility model has the basic structure of common drilling machine, and it has cast iron base 25, and Y-axis horizontal driving device is housed on it, and this device is mainly driven by screw mandrel Y-axis 23, screw mandrel pair 24, the step of driving Y-axis 23. The feeder motor 22 is formed, and the screw mandrel pair 24 is connected to drive the box-type mobile workbench 1. The right side of the base 25 is equipped with a vertical bed 15, and the upper part of the bed is equipped with a screw rod Z-axis up and down drive device, which is mainly composed of a screw rod X-axis 14, a screw rod pair 13, and a screw rod Z-axis 14. The stepper motor 12. The screw pair 13 is connected to drive the drill arm 11, the main motor 10 is installed on the drill arm 11, and the drill jacket 9 and the drill bit 7 are connected to the main motor 10; under the drill bit 7, a cantilever is connected to the vertical bed 15 Bracket 21, bracket 21 head end is equipped with automatic bracket cover 18.

The utility model has made the following improvements: a rotary head 5 is housed on the table top of the mobile workbench 1, and a stepper motor 2 is installed below the table top to connect and drive the rotary head 5.

A dust suction chamber 8 is provided below the drill jacket 9 , and a dust suction chamber 20 is installed on the cantilever bracket 21 . Two dust suction chambers 8 and 20 are connected to a vacuum cleaner 17 through suction pipes 16 and 19 .

The working principle of the utility model is briefly described as follows: install the friction plate 4 on the rotary head 5, lock it through the lock nut 6, and tighten the lock bolt 3 for positioning. The three stepping motors 2, 22, 12 in the utility model are all controlled by the microcomputer control system; automatically complete the respective feeding amount according to the program. First, after the machine tool is started, the mobile table 1 slides on the Y axis 23, and when the workpiece 4 moves to the point where the size of the distribution circle of the hole is aligned with the rotation center of the drill bit 7, the sliding stops. Now drill bit 7 descends drilling, and when this hole is a through hole, automatic support piece cover 18 descends; When this hole is a step hole, automatic support piece cover rises. After the hole is drilled, the rotary head 5 automatically rotates at a certain angle according to a given value to align the position of the next hole with the drill bit 7, and starts drilling until all the holes are drilled. Lower the workpiece and enter the processing of the next piece. During the drilling process, the vacuum cleaner 17 works to absorb the drilling dust and keep the working environment clean.
