Rapid pressing mechanism for mechanical manufacturing

The rapid pressing mechanism for mechanical manufacturing comprises an installation box and a top cover, the top cover is arranged at an opening in the top of the installation box, a plurality of sets of auxiliary pipes are evenly arranged in the middle of the top cover in the longitudinal direction, and a supporting plate extending transversely is fixed to the tops of the auxiliary pipes. The two sides of the top cover are provided with a plurality of groups of piston cylinders corresponding to the auxiliary pipes; an air hole is formed in the middle of the auxiliary pipe, the bottom end of the auxiliary pipe vertically penetrates through the top cover, and a sealing disc abutting against the bottom side of the top cover is fixed to the bottom end of the auxiliary pipe. The device has the beneficial effects that a plurality of groups of supporting plates are pressed down by virtue of the dead weight of a workpiece, so that the auxiliary pipe is driven to integrally move downwards, and the air holes extend in
