During processing, match one corner of the thin plate with the positioning block a40, and then cooperate with the remaining positioning blocks b50 to determine the position of the thin plate. At this time, a punching device is used to punch the predetermined hole position. When punching, the drill bit will enter the auxiliary processing mold after passing through the thin plate. The processing hole 2038 of 203 can avoid damage to the mold and improve the punching efficiency. It should be noted here that the processing disk 2036 will support the punching position of the thin plate during punching to avoid deformation during punching. The upper surface of the processing disk 2036 is flush with the upper surface of the supporting plate 30. When the position of the auxiliary processing mold 203 needs to be adjusted, first loosen the spiral locking disk 2035, and then move it as a whole along the axial direction of the suspension 20. After moving to the specified position, tighten the spiral locking disk 2035. At this time, the inclined platform 2033 is adapted to the oblique through groove 202, and the processing disk 2036 with different processing hole 2038 apertures can be selected according to the size of the punching.
