Further, described hold down gag and positioner are provided with altogether four groups, and are symmetricly set on base (1).
Further, described resilient key (7) top is set to taper.
Further, described depression bar (4) front end is removably provided with pressure head (401).
Further, described limited block (9) is arranged on the side of location key seat (5) by mosaic mode, and extends to location key seat (5) interior hollow section, matches with the chute (701) of resilient key (7).
The beneficial effects of the utility model: 1, according to the structure tight junction block of multiple alignment pin locks of workpiece, adopt automatic pressure head to compress, thus realize clamping workpiece compression, and locating surface develops completely, improves clamping efficiency.
2, ensure to realize the correct Set and Positioning of workpiece, improve passing rate of processing.
3, effectively prevent the junction block surface of sky cavity shape structure by the bad distortion of folder, avoid part to process and damage.
4, adopt the structure of taper pin, the size tolerance requirements for hole reduces, and resilient key according to the pore size auto lock of locating hole, can not need extra specially locating and machining hole, save process time and processing cost.
