AI Technical Summary
The existing tooling for machining the multi-angle mother body of triple eccentric butterfly valves makes it difficult to ensure the consistency between the tooling center height and the valve body center height during the machining process. This results in the tooling not being universal, increasing costs and production cycle.
By using a base fixture combined with wedge pads at different angles, and connecting them with positioning pins and double-ended studs, the multi-angle valve body slope fixture can be replicated, ensuring the consistency of the fixture's center height.
The number of tooling items was reduced, costs were lowered, production flexibility was improved, and the production cycle was shortened.
