[0038] The working principle and use process of this utility model:

[0039] First, the operator places the metal part inside the second clamping block 11, and then rotates the threaded rod 13 inside the second clamping block 11 to make the movable clamping plate 12 descend and clamp one end of the metal part. Then the operator starts the driving motor 2 to make the rotating shaft 3 drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the first moving plate 7 and the second moving plate 8 to move toward each other along the inner surface of the movable groove 6 through the two hinged rods 5, changing the distance between the first moving plate 7 and the second moving plate 8, so that the other end of the metal part is inserted into the first clamping block 10. Then the operator fixes the other end of the metal part. Then the operator starts the first pneumatic cylinder 20 to make the mounting block 21 descend as a whole, and automatically processes the metal part through the tool on the processing disk 24. When the processing position needs to be changed, the operator starts the power motor 15 to make the screw 16 rotate. The rotation of the screw 16 drives the socket block 18 to move left and right, so as to change the processing position of the metal part. When the tool needs to be replaced, the operator starts the tool changing motor 22 to make the circular shaft 23 drive the processing disk 24 to rotate as a whole, so that different tools can be automatically replaced.

[0040] When the operator needs to process the back of the metal part, the operator starts the second pneumatic cylinder 26, so that the connecting block 27 and the tooth plate 28 move backward under the limiting action of the limit block 29. Due to the meshing connection between the tooth plate 28 and the gear 31, the movement of the tooth plate 28 drives the gear 31 and the movable shaft 30 to rotate, and then the second clamping block 11, the first clamping block 10 and the clamped metal part rotate with the cooperation of the rotating rod 32, so that the metal part is flipped over, and then the operator can process it.
