In the scheme, the method comprises the following steps: the pressing block comprises a pressing block body and a connecting block, the pressing block body is fixedly connected below the connecting block through a bolt, and the pressing block body is fixedly connected to the lower end of the lug plate through the connecting block. The pressing block is designed to be composed of a connecting block and a pressing block body, the distance between the pressing block and the supporting block is adjusted, and the pressing block body can be conveniently replaced to enable the application range of the pressing mechanism to be wider.

In the scheme, the method comprises the following steps: the middle part of the lower side of the pressing block body is provided with a convex part extending downwards, and the position of the convex part is matched with the top end position of the supporting block.

Has the advantages that: the utility model discloses a perpendicular hold-down mechanism suitable for part of different thickness can realize not needing to change the frock or change the compact heap just can compress tightly the part when treating to compress tightly part thickness variation, and application scope is wide, reduces the production facility input of enterprise, improves work efficiency, reasonable in design, simple structure.
