When the tool clamp is used for machining the valve seat sealing surface of the valve body, the different end flanges on the two sides of the valve body are used as machining references, and the specific method comprises the following steps: and after the sealing surface of the valve body on one side is machined, the valve body is taken down from the inclination tool fixture, then the flange at the end of the other side of the valve body is taken as a positioning reference, the valve body is installed on the inclination tool fixture again, and the sealing surface of the other side of the valve body is machined after being found accurately.
The inventor finds that the method has the defects that: 1. when two end flanges on two sides of the valve body are not parallel or coaxial, machining errors can occur on two sealing surfaces of the valve body; 2. because two end flanges at two sides of the valve body are used as positioning references and need to be exchanged in the machining process, repeated measurement and calibration are needed for re-clamping of the valve body, and therefore machining efficiency is low and machining errors are large; 3. the flexible processing of sealing surfaces in valve bodies with different sizes cannot be realized.
