[0039] Specifically, the servo motor 7 can drive the left hollow rod 5 to rotate. The pulley 11 on the outside of the left hollow rod 5 is connected to the motor. When the servo motor 7 is started, the pulley 11 will rotate accordingly. The pulley 11 on the outside of the movable column 10 corresponds to the pulley 11 on the outside of the left hollow rod 5. When the left pulley 11 rotates, it is connected to the pulley 11 on the outside of the right movable column 10 through the belt, thereby driving the right movable column 10 to rotate, and the universal joint parts clamped therein will also rotate accordingly. This design makes it possible to perform multi-angle processing on the universal joint parts without the need for the staff to constantly manually adjust the angle of the parts. This processing method not only greatly improves the processing efficiency of the universal joint parts, but also ensures the consistency and accuracy of the processing.

[0040] Reference Figure 1 and Figure 3 The disassembly mechanism 2 includes a movable rod 201, and the plurality of movable rods 201 are respectively slidably connected to the inside of the corresponding hollow rod 5. Holes 202 are provided on the upper and lower sides of the tops of the two movable rods 201, and a spring 203 is fixedly connected to one side of the inside of the hole 202. One end of the spring 203 is fixedly connected to a limiting rod 204. Limiting holes 205 are provided on the upper and lower sides of the two hollow rods 5.

The two rubber pads 207 are respectively fixedly connected to the adjacent sides of the arc-shaped clamping plate 206. The sizes of the two movable rods 201 match the internal sizes of the corresponding hollow rods 5.

[0041] Specifically, when the universal joint part to be processed has a special shape, pressing the limit rods 204 on both sides can squeeze the spring 203, generating enough force to make the limit rods 204 disengage from the limit holes 205. Once the limit rods 204 are disengaged from the limit holes 205, they can freely enter the hole 202. At this time, the arc clamping plate 206 can be easily removed. After removing the arc clamping plate 206, the operator can select a suitable clamping plate for replacement according to the specific shape of the part to be processed. The design of this clamping plate takes into account a variety of part shapes, so it can meet a wide range of processing needs. By replacing the clamping plate, the device can achieve accurate clamping of parts of different shapes, thereby improving processing accuracy and efficiency.

The left and right sides of the outer wall of the bidirectional screw rod 15 are threadedly connected with movable blocks 16. The tops of the two movable blocks 16 are respectively fixedly connected to the bottoms of the corresponding U-shaped plates 3. The front and rear sides of the two movable blocks 16 are fixedly connected with sliders 17. The front and rear sides of the opening slot 13 are provided with slide grooves 18 on the left and right ends, and the sliders 17 are respectively slidably connected to the corresponding slide grooves 18.

[0043] Specifically, the servo motor 14 can drive the bidirectional screw rod 15 to rotate, and the movable block 16 on the outer side thereof will move toward the middle accordingly, and at this time, the universal joint parts of different sizes can be clamped.

[0044] Reference Figure 1 A controller 19 is fixedly connected to the front right side of the top of the base 1. The controller 19 is electrically connected to the servo motor 7 and the servo motor 14 respectively. A protective cover 20 is provided on the outside of the controller 19. One side of the protective cover 20 is rotatably connected to the top of the base 1.

[0045] Specifically, the operation of the servo motor 7 and the servo motor 14 can be controlled by the controller 19 , and the protective cover 20 can protect the controller 19 from being damaged by external factors.

[0046] Working principle: When using the device, first observe the size of the universal joint part to be processed, and then place it between the two arc-shaped clamping plates 206. Then, the servo motor 14 can drive the bidirectional screw rod 15 to rotate, and the movable block 16 on the outside will move toward the middle, and the U-shaped plate 3 will drive the arc-shaped clamping plate 206 to move toward the middle to limit the universal joint part. Then, the servo motor 7 can drive the left hollow rod 5 to rotate, and the pulley 11 on the outside of the left hollow rod 5 will rotate accordingly, and the pulley 11 on the outside of the corresponding movable column 10 will also rotate accordingly. At this time, the right movable column 10 will rotate accordingly, thereby driving The right hollow rod 5 rotates to drive the clamped universal joint parts to rotate, so that the universal joint parts can be processed at multiple angles. There is no need for the staff to constantly manually adjust the angles of the universal joint parts, thereby improving the processing efficiency of the universal joint parts and meeting the needs of users. When the universal joint parts to be processed are other shapes, the limit rods 204 on both sides are pressed, and the squeezing force of the spring 203 will drive the limit rods 204 to disengage from the limit holes 205 and enter the holes 202. Then the arc-shaped clamping plate 206 can be removed, and the corresponding clamping plates can be replaced according to the shapes of different parts, thereby improving the practicality of the device.
