Abstract

The invention relates to a ball valve body valve stem hole processing tool set which comprises a mounting base for connecting with a chuck, wherein the mounting base is provided with a mounting surface for mounting a ball valve body; the mounting surface is perpendicular to the end surface of the chuck; the mounting surface is perpendicularly provided with a connecting rod which is sheathed by the ball valve body; and the upper end of the connecting rod is provided with a pressing block for compacting the ball valve body. When being used for processing operation, the processing tool set has the advantages of convenient workpiece replacement, short adjustment time, small positioning error and low manufacturing and maintenance cost, is easy for assembly and disassembly, can well perform positioning, can be used for turning and boring, is also suitable for the processing center to use, does not need repeated sizing during the CNC processing, and is convenient for implementing mass production.

Description

technical field [0001] The invention relates to a tooling for processing a stem hole of a ball valve body. Background technique [0002] As a control element, the ball valve is widely used in various pipelines. In the structure of the existing ball valve, the stem hole of the valve body is perpendicular to the valve flange, which is not conducive to quick clamping in the production process. [0003] The existing processing technology generally uses a four-jaw chuck for clamping, turning or boring after correction. The production efficiency is low, and the correction time is long when clamping. There are also machining centers, which also have clamping problems. And its processing cost is high. Especially for small batch processing, the cost per piece is higher. [0004] On the other hand, the stem hole of the ball valve and the valve body channel have verticality and position requirements. The traditional positioning method requires multiple adjustments, but it still can...
