Quick gear clamping and positioning device

The utility model relates to a rapid gear clamping and positioning device, and belongs to the technical field of product machining. The positioning device is divided into two parts, namely three positioning blocks, three adapter seats and locking screws, the positioning surface at one end of the positioning block is matched with the groove of the adapter and is fixed through a locking screw, and the other end of the positioning block is provided with a positioning rod matched with the pitch circle of the part. According to the positioning device, the chuck of the machine tool is used for providing clamping force, the clamping force directly acts on the pitch circle of the part, the part is rapidly and reliably clamped, disc parts and planetary gear parts are directly and reliably clamped through the device, extra pitch circle alignment is not needed in the machining process, a large amount of labor cost is saved, and the production period is shortened. 本实用新型涉及一种齿轮快速装夹定位装置，属于产品加工技术领域。本定位装置分为两个部分：3个定位块、3个转接座及锁紧
