The outer wall of the shell 1 is fixedly connected with the connector 10, and the outer wall of the shell 1 provides a fixed support for the connector 10. The inner wall of the connector 10 is plugged into the outer wall of the fixed handle 9, so that the fixed handle 9 can be plugged into the connector 10, and the turntable 6 is fixed. The outer wall of the cylinder 15 is rotatably connected to the inner wall of the shell 1, so that the cylinder 15 can rotate along the inner wall of the shell 1, and the outer wall of the fixed handle 9 is slidably connected to the inner wall of the cylinder 15, so that the fixed handle 9 can move laterally along the inner wall of the cylinder 15.

[0034] Reference Figure 2 - Figure 4 The outer wall of the turntable 6 is fixedly connected to the frame 12, so that when the turntable 6 rotates, it can drive the frame 12 to rotate. The inner wall of the frame 12 is threadedly connected with a threaded rod 7, so that the threaded rod 7 can move laterally along the inner wall of the frame 12 by rotation. The inner wall of the frame 12 is contacted and connected with a clamp 11, so that the clamp 11 can move laterally along the inner wall of the frame 12. The inner wall of the clamp 11 is rotatably connected to the side of the threaded rod 7, so that when the threaded rod 7 moves laterally, it can drive the clamp 11 to move laterally. The outer wall of the shell 1 is hinged with a protective door 2, so that the protective door 2 can be opened outward along the inner and outer walls of the shell 1. The protective door 2 is fixedly connected to the outer wall of the shell 1 by a latch 8, so that when the protective door 2 is closed, it can be fixed to the outer wall of the shell 1 by the latch 8, and the iron filings will not splash. The inner wall of the bottom end of the shell 1 is slidably connected with a collection box 3, so that the iron filings generated during processing can fall into the collection box 3 for unified treatment.

[0035] Reference Figure 1 , Figure 6 The top of the shell 1 is fixedly connected to a motor 4, which provides a fixed support for the motor 4 through the top of the shell 1. The output end of the motor 4 is fixedly connected to a telescopic rod 14, so that the motor 4 can drive the telescopic rod 14 to rotate.

The outer wall of the telescopic rod 14 is fixedly connected to a drill bit 5, so that when the telescopic rod 14 rotates, it can drive the drill bit 5 to perform a circular motion and can drive the drill bit 5 to move vertically.

[0036] Reference Figure 2 - Figure 4 One end of the spring 13 is fixedly connected to the inner wall of the cylinder 15, and the other end of the spring 13 is fixedly connected to the outer wall of the fixed handle 9, so that when the fixed handle 9 stops being pulled, the fixed handle 9 can move inward due to the elastic force of the spring 13.

[0037] Working principle: When using the device, first release the fixing of the protective door 2, then open the protective door 2 outward, then place the flange to be processed on the inner wall of the frame 12, and then rotate the two sets of threaded rods 7 to drive the two sets of clamps 11 to clamp and fix the flange, then close the protective door 2, fix the protective door 2 to the outer wall of the shell 1 through the latch 8, and then start the telescopic rod 14 to drive the drill bit 5 to move downward, and then start the drill bit 5 to drill the top of the flange. When a hole is processed, start the telescopic rod 14 to drive the drill bit 5 to move upward, and then start the motor 4 to drive the telescopic rod 14 and the drill bit 5 to rotate, so that the drill bit 5 moves to the next place where a hole needs to be drilled.

[0038] When the drilling process on the top of the flange is completed, the drill bit 5 is stopped first, and then the telescopic rod 14 drives the drill bit 5 away from the top of the flange, and then the fixed handle 9 is pulled outward to release it from the plug-in connection with the plug-in component 10, and then the fixed handle 9 is rotated, and the cylinder 15 and the turntable 6 are driven to rotate at the same time. When the turntable 6 rotates, it will drive the flange clamped inside the frame 12 to rotate, so that the bottom end of the flange rotates upward, and then the fixed handle 9 is released. The fixed handle 9 will move inward due to the elastic force of the spring 13 and be plugged with the plug-in component 10, so as to achieve the effect of fixing the flange after rotation.

[0039] When drilling the flange, the iron filings generated will fall into the collection box 3 on the inner wall of the bottom end of the shell 1, and then be collected uniformly by the staff after the processing is completed.
