A clamping method for a universal clamp for the sealing surface of a valve body used in a vertical machine tool

Abstract

A universal clamp for the sealing surface of a valve body used in a vertical machine tool and a clamping method thereof, including a clamp body, the upper surface of the clamp body forms an included angle of 5 degrees with the horizontal direction, effectively ensuring that the processed wedge The consistency and accuracy of the angle of the sealing surface of the valve body of the gate valve or the sealing surface of the valve body of the swing check valve. The clamp body has an axisymmetric structure, which avoids the poor versatility of the clamps in the prior art for valve bodies of wedge gate valves of various sizes and models or valve bodies of swing check valves. , It is difficult to ensure the exact symmetry of the positions of the two relative valve body sealing surfaces, it is difficult to ensure the consistency and accuracy of the valve body sealing surface angle, and the valve body of the wedge gate valve or the valve body of the swing check valve is loaded and unloaded Inconvenient downside.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a clamping method for a universal fixture for a valve body sealing surface of a vertical machine tool. Background technique [0002] At present, the sealing surface of the valve body of the wedge gate valve or the sealing surface of the swing check valve used in the vertical machine tool needs to be clamped by special or general fixtures for processing, but the fixtures used so far Generally, the valve bodies of wedge gate valves or swing check valves with different sizes and specifications have poor versatility, and it is difficult to ensure that the sealing surfaces of the two opposite valve bodies are precisely symmetrical and Ensure the consistency and accuracy of the angle of the sealing surface of the valve body of the processed wedge gate valve or the sealing surface of the swing check valve The disadvantage of inconvenient loading and unloading of the valve ...

AI Technical Summary

Problems solved by technology

This structure avoids the common problems of the fixtures in the prior art, which are poor in versatility for the valve bodies of wedge gate valves or swing check valves of various sizes and models, and it is difficult to ensure that the two valves facing each other The position of the sealing surface of the body is accurate and symmetrical, and it is difficult to guarantee the consistency and accuracy of the angle of the sealing surface of the valve body of the wedge gate valve or the sealing surface of the swing check valve. Disadvantages of difficulty in processing chip removal from the valve body and inconvenient loading and unloading of the valve body of the wedge gate valve or the valve body of the swing check valve
