Description

A fixture for machining a water jet propulsion pump body

Technical Field

The utility model relates to the technical field of a clamp for processing a pump body, in particular to a clamp for processing a water jet propulsion pump body.

Background Art

At present, when processing the pump body, it is generally necessary to fine-process the connecting end surface of the pump body. After the pump body is fixed by the clamp used in the prior art, it is difficult to flip the pump, and it needs to be dismantled and reinstalled for processing. The water jet propulsion pump body is often large in size and heavy, and re-disassembly and reassembly is time-consuming and laborious. Therefore, most manufacturers use a flip-type clamp to clamp and fix the pump body. However, because the outer surface of the pump body has an arc, it is very easy to cause the clamp to clamp the pump body unstably during the flipping process.
