Abstract

The invention discloses a fixing device for grinding of a rear axle shaft sealing cover. A round blind hole is formed in a machine frame in the vertical direction, and a square blind hole is formed in the machine frame in the horizontal direction. A cylindrical pull rod slides in the round blind hole, and a cuboid sliding block slides in the square blind hole. A first through hole is formed in the middle of the pull rod, a first wedged face is arranged on the lower inner wall of the first through hole, and a second wedged face is correspondingly arranged in the middle of the sliding block. A screw rod is integrally arranged at the outer end of the sliding block, one end of a threaded cover is connected with the screw rod through threads, and the end face of the end of the threaded cover abuts against the side wall of the machine frame; the other end of the threaded cover is fixed to a handle, a positioning block is embedded into the upper end of the round blind hole, and a second through hole for the pull rod to slide is formed in the center of the positioning block; a pressing plate is connected to the upper end of the pull rod in a sleeving mode, and the pressing plate and the pull rod are locked through a nut. A spring is fixed between the bottom of the square blind hole and the bottom of the pull rod. By means of the fixing device, a workpiece can be clamped and positioned and can be quickly clamped, so that efficiency is greatly improved.

Description

technical field [0001] The invention relates to a clamp, in particular to a fixing device for grinding the sealing cover of a rear car half shaft. Background technique [0002] The half-shaft seal cover is an important security part on the rear axle of the car. During the operation of the car, it bears the weight of the entire body and the on-board cargo. At the same time, due to changes in road conditions, it has to withstand various complex alternating stresses. Therefore, the quality of the half shaft sealing cover directly affects the driving safety of the vehicle. [0003] In the prior art, the half shaft sealing cover is usually made by forging, and many burrs are generated on its surface, which needs to be polished. Generally, workers carry out fixed processing by hand-held method, and the processing quality is difficult to guarantee, and it is also unsafe and low in efficiency. SUMMARY OF THE INVENTION [0004] The present invention aims to provide a fixing devi...
