It is provided with a coil component spring silk；A steel ball is provided at the top of three copper telescopic pins；The top of the locating shaft
Portion's also activity insertion is equipped with a hold-down bolt；A workpiece is provided on the outside of the locating shaft.
Further, the flat panel workpieces inner hole and positioning shaft clearance are designed as 0.5-1mm.
Further, copper telescopic pin can be allowed in the movable empty slot in inside there are three the inside settings of the locating shaft, and
The side of copper telescopic pin is ramp-like structures, and the top on three copper telescopic pin sides inclined-plane is arranged in steel ball.
Compared with prior art, the utility model has the following beneficial effects:
Inner hole of workpiece and positioning shaft clearance are designed as 0.5-1mm, and when free state, coil component spring silk is copper flexible by three
Pin is limited in pin hole, and when screwing hold-down bolt, steel ball is outside along radial direction by three copper telescopic pins of slope driving
It stretches out, oppresses inner hole of workpiece surface, realize that the quick positioning and clamping of workpiece, the present apparatus solve Internal hole positioning Quick-clamped and ask
Topic greatly reduces the time that dress takes workpiece, improves working efficiency while guaranteeing to position validity.
