Valve body shaft hole machining clamping mould

Abstract

The invention discloses a valve body shaft hole machining mould which comprises a T-shaped positioning plate assembled with a lathe faceplate through a guide rail, a rotating body of a T-shaped structure is installed on the plane portion of the T-shaped positioning plate, and the rotating body is provided with a cylindrical portion matched with a valve body to be machined and a bottom plate connected with the cylindrical portion. A lower protruding column assembled together with an upper round hole of the plane part in a rotating fit mode is formed at the bottom of the bottom plate, a rotatingbody pressing plate is arranged on the plane part so as to press the rotating body on the plane part to be fixed, and a valve body fixing plate is installed at the upper end of the rotating body through a bolt in a connected mode. The positions of the bottom plate and the plane part of the rotating body are positioned through positioning pins. According to the valve body shaft hole machining clamping mould, through the technical scheme, a corresponding valve body can be conveniently positioned, so that shaft holes in the two sides of the valve body are conveniently machined, the structure issimple, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a mold for machining a shaft hole of a valve body. Background technique [0002] Due to the butterfly valve (see Figure 5 As shown), the valve body has a special structure, which has a cylindrical part, and on both sides of the cylindrical part, there is a radial pipe body connected through the cylindrical part. Therefore, there are difficulties in processing and positioning, especially in processing The problem of inconvenient positioning exists in the shaft holes of the two radial pipe body parts. Contents of the invention [0003] The object of the present invention is to provide a mold for machining the shaft hole of the valve body aiming at the technical defects in the prior art. [0004] The technical scheme adopted for realizing the purpose of the present invention is: [0005] A valve body shaft hole processing tire, including a T-shaped positioning plate ass...
