Fixing device

The invention discloses a fixing device. The device comprises a tool body which is made of a hard material, and the interior of the tool body is a cavity; the cavity is of an I-shaped structure; a plurality of blind holes are formed in the top face of the cavity and used for containing parts to be machined. A clamping groove is formed in the bottom of the cavity and used for containing a supporting plate. A threaded hole is formed in the supporting plate and used for allowing a puller bolt to penetrate into and abut against the part to be machined. The base is arranged at the bottom of the tool body and fixedly connected with the tool body. According to the device, the multiple axial and radial limiting mechanisms, namely the blind holes and the puller bolts, are arranged in the cavity of the device, a batch of parts to be machined can be machined uniformly after being clamped and fixed at a time, and therefore the machining efficiency is improved. 本发明公开一种固定装置。该装置包括：工装主体，所述工装主体由硬质材料制成，所述工装主体的内部为空腔；所述空腔为工字结构；于
