Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a positioning clamping tooling for processing a water pump gas-liquid separator cover. Background Art

[0002] After casting, the existing water pump separator cover needs to be fine-machined on a lathe. However, the size or shape of the clamping end of the clamping claw on the axle in a general three-jaw axle clamp is fixed. When clamping and fixing axles of different sizes, it is difficult to fit well with the axle surface, and it is difficult to stably clamp axles of different sizes. During the axle processing, the axle is easy to fall off, affecting the processing efficiency of the axle. The three-jaw clamp for the axle with application number 2023215017067 includes a clamp base, and three groups of slide grooves are opened on the top of the clamp base. The three groups of slide grooves are slidably connected with clamping strips, which can facilitate the stable clamping of axles of different sizes and prevent the axle from falling off when the clamping is completed.

[0003] Although the device has the above advantages, it still has certain defects in actual use. Since the two ends of the cover body of the water pump separator are of different sizes and there is a certain distance between them, when it is clamped and fixed by the existing three-jaw clamp, no matter which end is clamped, the other end will swing to a certain extent during the processing, resulting in the cover body being unable to maintain a stable state, thereby reducing the processing accuracy. Therefore, it is necessary to solve the above problem. Utility Model Content
