Work fixture for processing brake valve body

Abstract

The invention discloses a work fixture for processing a brake valve body. The work fixture comprises a rotary tray for fixing a base of the valve body, a cover plate for pressing and giving the clamping force to a flange in the valve body, and a transform component arranged on the bottom part of a chassis and the right-angle sides of a fixed platform, wherein the rotary tray is arranged on the chassis; the chassis is arranged on the fixed platform with corners being right angle; a stop pin for fixing the rotary tray is arranged on the chassis; a stand column for supporting the cover plate is arranged on the fixed platform; the cover plate is detachably connected with the stand column; the transform component is used for transforming the chassis to be in the vertical state from the horizontal state along the right-angle sides of the fixed platform. The work fixture for the processing brake valve body is compact in structure, convenient to disassemble and assemble, simple and convenient to operate, safe and reliable, and strong in universality; the processing of multiple parts of the valve body can be finished through one-time clamping, and the processing efficiency can be greatly improved; the processing error can be reduced, the consistency of processing is ensured, and the processing quality is ensured; mass processing production can be carried out favorably.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a tooling fixture for processing a gate valve body, and belongs to the technical field of gate valve body processing equipment. Background technique [0002] The sealing effect of the valve is an important indicator to measure the quality of the valve. Ordinary valves generally use a lathe to turn the sealing surface, and then seal it with a soft sealing ring. The sealing effect of this type of valve mainly depends on the sealing ring, which is easy to use for a long time. Leakage, short lifespan, and low reliability. [0003] The existing hard-sealed valve has high reliability and long service life. After the sealing surface of this type of valve is turned, it is necessary to grind the sealing surface to make the valve sealing surface achieve higher flatness and roughness, so that a better sealing effect can be achieved without using a sealing ring. In order to ensure the tightness of the ...

AI Technical Summary

Problems solved by technology

This kind of processing method is not only cumbersome and difficult to clamp; moreover, multiple clamping operations and step-by-step processing of the sealing surface make it difficult to guarantee the consistency of the shape tolerance and dimensional tolerance of the processed sealing surface, and the effect is not good and The process of changing fixtures is also time consuming and can lead to overall inefficiency in the operation

In addition, the processing of the flange part in the valve body needs to be re-clamped and processed, and there is also the problem of low processing efficiency.
