Both sides of the inner cavity of the placing frame 41 are threadedly connected with threaded rods 42 through threaded grooves, and one end of the threaded rod 42 is rotatably connected to a clamping frame 43 through a bearing. As a detailed explanation: limited sliding holes are provided on both sides of the placing frame 41, and one side of the clamping frame 43 is fixedly connected with a limited sliding rod used in conjunction with the limited sliding holes. The top of the processing table 1 is fixedly connected with a mounting frame 5, and one side of the mounting frame 5 is fixedly connected with a driving motor 6 through a bracket. The output shaft of the driving motor 6 is fixedly connected with a second reciprocating screw 7 through a coupling, and one end of the second reciprocating screw 7 extends to the interior of the mounting frame 5 and is rotatably connected to one side of the inner cavity of the mounting frame 5. The surface of the second reciprocating screw 7 is threadedly connected with a threaded sleeve 8, and a grinding assembly 15 is fixedly arranged at the bottom of the threaded sleeve 8. As a detailed explanation: the grinding assembly 15 is composed of a motor and a grinding disc, and an intermittent transmission mechanism 9 is provided between the threaded sleeve 8 and the first reciprocating screw 2;

[0023] In order to facilitate the scrap protection of the threaded rod 42, the two clamping frames 43 are fixedly connected to the opposite sides thereof with arc-shaped shielding plates 14 used in conjunction with the threaded rod 42;

[0024] As a detailed explanation: a cross slide groove 10 is opened on the top of the processing table 1, a cross slide block 11 slidably matched with the cross slide groove 10 is fixedly connected to the bottom of the placement frame 41, a guide groove 12 is opened on the top of the inner cavity of the mounting frame 5, and a guide block 13 slidably matched with the guide groove 12 is fixedly connected to the top of the threaded sleeve 8.

[0025] Furthermore, in order to facilitate the regular and orderly movement and grinding of the metal plate, the intermittent transmission mechanism 9 includes a slide plate 91, which is fixedly arranged on the top of the processing table 1, and the slide plate 91 is slidably connected to a slide cylinder 92 inside the slide plate 91, and a first return spring 93 is fixedly connected between the slide cylinder 92 and the slide plate 91, and a shank tooth plate 94 is slidably connected to the slide cylinder 92 inside the slide cylinder 92, and a second return spring 95 is fixedly connected between the shank tooth plate 94 and the slide cylinder 92, and a gear 96 meshing with the shank tooth plate 94 is fixedly connected to the surface of the first reciprocating screw 2, and a guide plate 97 is fixedly connected to the bottom of the slide plate 91 through a bracket, and a guide roller 98 used in conjunction with the guide plate 97 is fixedly connected to the front side of the shank tooth plate 94, and a push plate 99 used in conjunction with the shank tooth plate 94 is fixedly connected to the front side of the threaded sleeve 8.

The first reciprocating screw 2 rotates the threaded sleeve 3 to drive the metal plate to intermittently move forward through the fixing mechanism 4. When the corresponding threaded sleeve 8 pushes the shank tooth plate 94 to move to the right to the extreme position through the push plate 99, the guide roller 98 connected to the shank tooth plate 94 will drive the shank tooth plate 94 to move up and automatically return to its original position to the left due to the bevel cooperation with the other side of the guide plate 97.
