Universal valve body sealing surface clamp for horizontal machine tool and clamping method of universal valve body sealing surface clamp

Abstract

The invention relates to a universal valve body sealing surface clamp for a horizontal machine tool and a clamping method of the universal valve body sealing surface clamp. The universal valve body sealing surface clamp for the horizontal machine tool comprises a clamp body adopting an axisymmetric structure, and is connected with the spindle of the horizontal machine tool; and a 5-degree included angle is formed between the universal valve body sealing surface clamp and the vertical direction. Such a structure avoids the defect that a clamp in the prior art generally has poor universality for the valve bodies of wedge gate valves or swing check valves of various sizes, specifications and models, can hardly ensure accurate symmetry of the positions of two opposite valve body sealing surfaces and the consistency and accuracy of the angles of the valve body sealing surfaces, and cannot load and unload the valve bodies of wedge gate valves or swing check valves conveniently.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a universal fixture for a valve body sealing surface used in a horizontal machine tool and a clamping method thereof. 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 horizontal machine tools needs to be clamped by special or general-purpose fixtures for processing, but the general-purpose fixtures used so far Fixtures generally have poor versatility for the valve bodies of wedge gate valves or swing check valves of various sizes and models, and it is difficult to ensure the exact symmetry of the sealing surfaces of the two opposing valve bodies. It is difficult to ensure the consistency and accuracy of the angle of the sealing surface of the valve body, and the disadvantages of inconvenient loading and unloading of the valve body of the wedge gate valve or ...

AI Technical Summary

Problems solved by technology

Such a structure avoids the universality of the universal fixtures in the prior art, which generally has poor 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 relative The position of the sealing surface of the valve body is accurate and symmetrical, it is difficult to ensure the consistency and accuracy of the angle of the sealing surface of the valve body, and the valve body of the wedge gate valve or the valve body of the swing check valve is inconvenient to install and disassemble.
