The beneficial effects of the utility model are: the design of the detent mechanism matched with gear ring to be processed is contacted with the reference circle of gear ring by place kick, and the end face of support body end face to workpiece gear ring compresses, the cooperation of the place kick of being exposed by support body third through-hole and the positioning chamber of corresponding circular arc on the inwall of clamp body centre bore by workpiece locking positioning on clamp body, achieve the accurate location clamping of gear ring, reduce the circular runout of gear ring grinding out operation, avoid gear ring due to the hole thin extremely yielding situation of wall greatly.In a word, the utility model structure is simple, reasonable in design compact, and can realize the accurate location clamping of gear ring, trade union college positioning and locking efficiency is high, installs, dismounting workpiece is very convenient, improve the quality of gear ring grinding out processing, avoid the phenomenon that gear ring is out of shape.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described place kick is steel ball, and described positioning belt is steel band, and its two ends are welded on the inner periphery of support body described in described steel ball both sides.
Adopt the beneficial effect of above-mentioned further scheme to be that detent mechanism will contact with the reference circle of gear to be processed, place kick retainer implements the intensity of location to workpiece to adopt steel matter ensure that.
