The existing solution is to use modular design and replace the fixtures for different shaped parts. However, in actual use, this is not only very cumbersome to operate, but also increases the production cost of the device.

Mounting seats 9 are fixedly connected to the tops of the two locking seats 8, and the mounting seats 9 and locking seats 8 are integrally formed. By inserting the locking seats 8 along the inner side of the engaging grooves 7 and sliding them to both sides, the clamping assembly can be quickly installed. Limiting grooves 10 are provided on the front and rear sides of the mounting seat 9, and sliders 11 are slidably connected inside the multiple limiting grooves 10.

When fixing the arc part, the clamping base 8 is slid out and installed in the opposite direction so that the arc grooves 15 fit with the surface of the part. The top of the mounting base 9 is threaded with an adjusting bolt 13. The bottom end of the adjusting bolt 13 passes through the top of the mounting base 9 and is rotatably connected to a pressing block 14. At this time, rotating the adjusting bolt 13 drives the pressing block 14 to slide downward. The pressing block 14 is inserted between the two clamping plates 12.

Limiting grooves 10 are provided on both the front and rear sides of the mounting base 9. Sliding sliders 11 are slidably connected inside these limiting grooves 10. Clamping plates 12 are fixedly connected between the sliding sliders 11. Arc grooves 15 are provided on the opposite sides of the two clamping plates 12. This design allows the clamping plates 12 to flexibly adapt to different shapes. When clamping a flat part, the clamping plate 12 is installed in the mounting base 9. One side can clamp and fix the surface of the flat part. When fixing a curved part, the clamping base 8 is slid out and installed in the opposite direction, so that the curved groove 15 fits against the surface of the part, thereby achieving precise clamping of the curved part. The top of the mounting base 9 is threaded with an adjusting bolt 13. When the part needs to be reinforced, the adjusting bolt 13 is rotated to drive the pressing block 14 to slide downward. The pressing block 14 is inserted between the two clamping plates 12. The clamping plates 12 are expanded outward by pressing, thereby completing the reinforcement of the part and improving the drilling accuracy. In addition, the left and right sides of the drive device 4 are fixed with reinforcing plates 23. The rear side of these reinforcing plates 23 is fixed to the front side of the protective plate 3.

In addition, the other end of the vacuum cleaner 201 is connected to an exhaust pipe 205, which is used to exhaust the air inside the vacuum cleaner 201. The nozzle 209 is connected to the fixing block 20. 8 is reinforced and installed on the outer wall of the output end of the drive device 4. When the output end drives the drill bit 5 for use, the nozzle 209 can remove debris from the drilling area and cool down the drill bit 5, thereby improving the service life of the drill bit 5. The other end of the exhaust pipe 205 passes through the rear side of the protective plate 3 and is connected to the outer wall of the nozzle 209. The outer wall of the exhaust pipe 205 is connected to the connecting pipe 206.

In order to further prevent the debris from splashing, a slope plate 210 is also fixedly connected to the top rear side of the processing table 1. The slope plate 210 can effectively guide the debris to slide down the slope and avoid the debris from splashing.
[0036] Reference Figure 1 and Figure 2 Push rods 16 are fixedly connected to both the left and right sides of the processing table 1. Anti-slip sleeves 17 are fixedly connected to the outer wall of the push rods 16. A controller 18 is fixedly connected to the front side of the processing table 1.

[0038] Working principle: First, the part is placed in the middle of the machining base 6. The clamping seat 8 is inserted along the inner side of the engagement groove 7 and slid to both sides to quickly install the clamping assembly. Depending on the shape of the part, one side of the clamping plate 12 can clamp and fix the surface of the flat part. When fixing the curved part, the clamping seat 8 is slid out and installed in the opposite direction so that the curved groove 15 fits against the surface of the part. The pressing block 14 is slid down by rotating the adjusting bolt 13. The pressing block 14 is inserted between the two clamping plates 12. The clamping plates 12 are expanded outward by pressing, thereby completing the reinforcement of the part and improving the drilling accuracy.
[0039] Furthermore, by activating the vacuum cleaner 201, excess air is expelled through the exhaust pipe 205, and debris remaining on the surface of the processing table 1 is removed through the air outlet box 207, causing it to fall into the dust collection box 203. The dust collection box 203 is installed on the rear side of the processing table 1, at the same level as the processing table 1, allowing debris to fall into it more easily. The filter plate 204 effectively filters the debris, preventing it from entering the vacuum cleaner 201. The debris is emptied by removing the dust collection box 203. At the same time, the nozzle 209 is reinforced and installed on the outer wall of the output end of the drive device 4 by the fixing block 208.
