Abstract

A tool for running-in machining of a ball body and a valve seat of a ball valve comprises a tool body. The tool body comprises a base, a support and a numerical control operation panel, wherein the base is provided with a ball body main shaft system; the support is provided with a ball body top loading device, an abradant conveying system and a guide rail mounting mechanism; the guide rail mounting mechanism is provided with a left grinding head main shaft system and a right grinding head main shaft system in a bilateral symmetry mode with the center line of the base as the center; the support is provided with a cross beam swing mechanism hinged to the guide rail mounting mechanism. The tool has the beneficial effects that the valve seat swings in a reciprocating mode around the center of the ball body through a crank and rocker mechanism, the reciprocating swinging motions are combined with respective rotations of the ball body and the valve seat to form a motion trail, the running-in precision of the ball body and the valve seat is higher through the three-motion synthesis mode, and the machining efficiency is higher.

Description

technical field [0001] The invention relates to a grinding processing technology, in particular to a tool for grinding and processing a ball and a valve seat in a ball valve. Background technique [0002] At present, grinding is mainly used when finishing the ball and seat in the ball valve. Grinding is divided into manual grinding and mechanical grinding. Manual grinding is to use manpower to manually grind the valve seat and the ball. This method is time-consuming and laborious, and the efficiency is extremely low. The grinding accuracy depends on the skills of the personnel. The stability is poor, and the grinding accuracy is not easy to control. Mechanical grinding is to use corresponding grinding equipment to grind the sphere. Generally, there are single-sided and double-sided. In the form of compound grinding, the grinding accuracy and efficiency obtained by this method are higher than those of the single-sided type. [0003] However, in the prior art, the ball rota...
