Modular location clamping mechanism

The utility model discloses a modular location clamping mechanism can eliminate layer board size difference and eliminate the work piece gyroscopic moment, when guaranteeing that the work piece location is abundant, accurate, has guaranteed the rigidity of frame and has avoided the atress of locating pin to be out of shape. Its technical scheme does: modular location clamping mechanism realizes to the work piece that the locating clip is tight, and the mechanism includes: the frame is installed to a base on, the work piece is located in the frame, backer's subassembly is installed at the top of frame, is equipped with a locating component on backer's subassembly, and the locating hole of a locating component and work piece top surface matees, the 2nd locating component sets up in one side of the first side of work piece, and the 2nd locating component matees with the locating hole that lies in the first side of work piece, the dog subassembly sets up in one side of the second side of work piece, and the first side and the second side of work piece are two relative sides.
