[0020] Two fixed blocks 8 are fixedly arranged on the inner top of the mounting frame 2 and the upper end of the processing seat 1, respectively. A slide bar 9 is fixedly arranged between each two fixed blocks 8. A slidable moving block 10 is passed through the two slide bars 9. An electric telescopic cylinder 11 is installed on one side of the mounting frame 2. The output shaft of the electric telescopic cylinder 11 passes through the mounting frame 2 and is fixedly connected to one side of the moving block 10.

The sliding seat 13 is fixed in the slide groove 12 by the fixing screw 14. The two sliding seats 13 can be fixed in the slide groove 12 respectively by the two fixing screws 14. Therefore, the position of the sliding seat 13 in the moving block 10 can be adjusted, thereby adjusting the upper and lower positions of the edges on both sides of the flange that need to be chamfered, so as to facilitate the chamfering of the edges on both sides of the flange at the same time.

[0021] A rotatable short shaft 15 is passed through the front end of the sliding seat 13, and a connecting rod 16 is fixed on the short shaft 15.

By pulling the limit rod 33, the top of the limit rod 33 is separated from the limit groove 31, so that the rotation of the rotating wheel 30 can be achieved. At this time, the return spring 34 is squeezed to generate elastic force, so that the angular position of the tool 17 can be adjusted. Afterwards, the limit rod 33 can be driven to return to the initial position by the return action of the return spring 34, so as to drive the top of the limit rod 33 to be pushed into the corresponding limit groove 31 again to limit the rotation of the rotating wheel 30, and finally the angular position of the tool 17 can be fixed.

[0023] The working principle of the utility model is as follows: the staff can place the flange on the upper end of the fixed disk 4, and rotate the handle 29 to drive the two second threaded rods 26 to rotate at the same time, so that the two threaded seats 28 can be moved along the two second threaded rods 26 respectively, and finally the two clamping rings 6 can be driven to move, that is, the flange can be fixed by the clamping ring 6 and the inner hole of the flange. Then, the position of the sliding seat 13 in the moving block 10 can be adjusted according to the size of the flange, so as to adjust the upper and lower positions of the edges on both sides of the flange that need to be chamfered. At the same time, the angular position of the tool 17 can be adjusted according to the size of the flange to adjust the angle of the chamfer. Finally, the mounting frame 2 can be driven to rotate by the motor 3, so as to drive the fixed disk 4 to rotate, so as to drive the fixed flange to rotate. At the same time, the moving block 10 is driven to slide to the right along the two sliding rods 9 by the electric telescopic cylinder 11, and finally the tool 17 can be driven to move to the right. Therefore, the edges on both sides of the flange can be chamfered at the same time by the tool 17, and the rotation of the flange is coordinated to complete the chamfering of the flange, thereby effectively increasing the chamfering efficiency of the flange.
