Abstract

The invention discloses a multi-meshing positioning type bulging clamping workbench mechanism which comprises a disc-shaped workbench. The disc-shaped workbench is provided with a clamping mechanism which comprises a center clamping mechanism and an edge clamping mechanism used for fixing the peripheral edges of disc parts. A workbench rotating shaft and a rotating drive mechanism used for driving the workbench to rotate are arranged below the workbench. The multi-meshing positioning type bulging clamping workbench mechanism further comprises a position locking mechanism used for locking the position of a rotating gear; the position locking mechanism comprises a meshing gear and locking hydraulic cylinders; a locking block is mounted on a piston rod of each locking hydraulic cylinder; and the locking blocks are provided with locking teeth meshing with the meshing gear. The included angles between the axis of one of the three locking hydraulic cylinders and the axes of the other two locking hydraulic cylinders are alpha and beta, wherein alpha is equal to 360*a / Z+360 / 4Z degrees, and beta is equal to 360*b / Z+360 / 4Z degrees, Z is the tooth number of the meshing gear, and a and b are both positive integers larger than or equal to one.
