Further, a groove is formed in the top of the positioning block, and the shape of the limiting block is triangular.

Further, the number of the short limiting pins is two, and the short limiting pins are symmetrically distributed on the left side and the right side of the bottom of the front face of the limiting block.

Further, handles are fixedly arranged on the left side and the right side of the bottom plate.

Further, the number of the elbow clamps is two, and the elbow clamps are symmetrically distributed on the left side and the right side of the front face of the positioning block.

Further, the number of the positioning columns is two, and the positioning columns are symmetrically distributed on the left side and the right side of the front face of the bottom plate.

Furthermore, the cushion blocks are fixedly arranged on the periphery of the bottom plate.

Compared with the prior art, the technical scheme of the application has the following beneficial effects:

this gear positioning fixture that three-dimensional detection used when putting into the recess with the gear when clamping the gear, insert on the locating piece with two short spacer pins again, insert the hole on the gear with long spacer pin, then use the elbow clamp to fix the gear on the locating piece, extract the locating pin again and expose the hole that just borrows with just fixing a position, push it in three-dimensional check out test set again this moment, just once can accomplish all measurement, do not need the secondary clamping when making three-dimensional measurement of gear, can once all measure, measurement accuracy has been improved, measurement time has been saved also avoided the mistake of artificial secondary clamping.
