Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a fixing fixture for processing a ship valve body and a processing method thereof. Background Art

[0002] Marine valves are devices used to control the pressure, flow rate and flow direction of fluids in ship pipelines to meet the ship's environmental conditions. In the production and processing of marine valve bodies, in order to ensure the stability of the valve body, it is usually necessary to use a fixed fixture to clamp and limit the valve body to avoid position deviation during the processing and ensure the processing effect.

[0003] When using traditional fixing clamps, their clamping form is usually fixed, so when clamping and processing marine valve bodies of different specifications, it is difficult to effectively adapt to the surface shape of the marine valve body, which is not conducive to ensuring the clamping stability of the marine valve body and easily affects the processing effect of the marine valve body. Summary of the invention
