[0022] Specifically, the processing platform 2 is slidably arranged on the operating table 1, and the workpiece is placed on the support plate 3 in the processing platform 2, wherein there are several processing platforms 2, and the diameter of the cavity 23 in each processing platform 2 is different. When processing a circular plate-shaped workpiece, a processing platform 2 whose cavity 23 has the same diameter as the workpiece is selected for use. By making the diameter of the cavity 23 the same as the diameter of the workpiece, the workpiece is limited so that when punching holes or engraving patterns on the surface of the workpiece, the workpiece will only produce a rotational offset at most, and will not slide horizontally or vertically. The correction component 5 drives the support plate 3 to rotate, so that after the workpiece is rotated and offset, it can drive the workpiece to rotate and restore it to its original position, and the clamp 4 squeezes and fixes the workpiece placed on the support plate 3.

[0023] A first T-shaped block 21 is fixedly connected to the lower surface of the processing platform 2, a first T-shaped slot 11 matching the first T-shaped block 21 is provided on the upper surface of the operating table 1, a locking bolt 22 is provided on the side of the operating table 1, the end of the locking bolt 22 extends into the first T-shaped slot 11 and is threadedly connected to the first T-shaped block 21, and a strip groove 12 matching the locking bolt 22 is provided on the side of the operating table 1.

[0024] Specifically, the processing platform 2 slides stably with the cooperation of the first T-shaped block 21 and the first T-shaped slot 11, so as to adjust the position of the processing platform 2 during processing. The locking bolt 22 slides through the strip slot 12, so that the locking bolt 22 can slide with the sliding of the processing platform 2.

The wedge block 61 slides, and under the pressure of the inclined surface, drives the support plate 3 to slide up and down. The support plate 3 moves downward, loosening the workpiece, so that the support plate 3 can drive the workpiece to rotate, so that the workpiece can be corrected without loosening the clamp 4.

[0029] A screw rod 62 is rotatably arranged on the side of the processing platform 2, and the end of the screw rod 62 passes through two wedge blocks 61 in one group. The circumferential sides of the two ends of the screw rod 62 are respectively provided with positive threads and negative threads. The screw rod 62 is threadedly connected to the two wedge blocks 61 through the positive threads and negative threads.

[0030] Specifically, the screw 62 is rotated. The screw 62 rotates, and under the action of the positive thread and the negative thread, it drives a group of two wedge blocks 61 to slide closer or slide away at the same time. The two wedge blocks 61 slide closer at the same time and drive the support plate 3 to move upward under the action of the inclined surface. The two wedge blocks 61 slide away at the same time, and the support plate 3 moves downward under the action of gravity.

[0031] The fixture 4 includes a stud 41 fixedly connected to the processing platform 2, and a bracket 42 is sleeved on the circumferential side of the stud 41. The end of the bracket 42 is inclined upward and extends to directly above the support plate 3.

A nut is threadedly connected to the stud 41 to fix the bracket 42. The rotating extrusion bolt 43 extrudes and fixes the workpiece under the action of the extrusion block 44.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] When correcting the deviation, it is only necessary to rotate the screw 62, which drives the wedge block 61 to slide, so that the support plate 3 moves down, loosening the workpiece, and then rotate the knob 52, which drives the gear 51 to rotate, and the gear 51 drives the support plate 3 to rotate to adjust the position of the workpiece, and then rotate the screw 62 in the opposite direction, and the wedge block 61 squeezes the support plate 3 to move up, thereby fixing the workpiece.
