Hobbing clamp

The utility model discloses a hobbing clamp, and belongs to the technical field of machining. Comprising a base, a positioning shaft, a limiting disc, a gland and a screw, a shaft hole is formed in the center of the base, the positioning shaft capable of ascending and descending is arranged in the shaft hole, the limiting disc for limiting the positioning shaft is arranged at the top of the base, a gear blank is fixed by screwing the screw into the positioning shaft in a threaded mode, and the gland is arranged between the screw and the top face of the gear blank. According to the tool, through the telescopic positioning shaft, the lifting distance of a workpiece is greatly shortened during mounting and dismounting, the gear can be conveniently pulled out, and rapid hoisting is achieved. And meanwhile, during fastening, the number of turns of screwing the screw is greatly reduced, the mounting efficiency is improved, and the labor intensity during mounting is reduced. 本实用新型公开了一种滚齿夹具，属于机械加工技术领域。包括底座、定位轴、限位盘、压盖
