Problems solved by technology

One of its disadvantages is that the clamping process affects the processing speed of the valve body, and the processing efficiency is low; the second disadvantage is that there is a position error in each clamping, which affects the two end faces of the valve body and the two valve seats in the valve body. Processing produces coaxial error, which affects the machining accuracy of the valve body

Abstract

The invention relates to an automatic-revolving indexing machining device which comprises a chuck and a clamping jaw. The clamping jaw is composed of an upper clamping jaw and a lower clamping jaw. The automatic-revolving indexing machining device is mainly characterized in that the upper clamping jaw is movably mounted in a shaft hole of a clamping piston by a mounting shaft, the clamping piston is mounted in a clamping oil cylinder on the chuck, the lower clamping jaw is in matched connection with a shaft hole in a turnplate by a mounting shaft, the turnplate is axially mounted on the chuck by a positioning block and is in radially movable fit with a chuck mounting hole, the middle section of an outer cylindrical face of the turnplate is made to be a polygonal column, a first oil cylinder and a second oil cylinder are arranged on the chuck on one side of the polygonal column, a first piston end and a second piston end extend into a plane of the polygonal column respectively, and a first piston and a second piston adopt a hydraulic system for interactive control. The first oil cylinder and the second oil cylinder sequentially push the turnplate to rotate, machining of multiple faces can be completed by clamping for one time, and the automatic-revolving indexing machining device has the advantages of high machining efficiency, few in machining error, high in machining accuracy and the like, and is a machining clamp suitable for key parts like a valve body and a valve cover of a valve.

Description

technical field [0001] The invention relates to a machining fixture. The invention is suitable for machining fixtures of key parts such as valve bodies and valve covers. Background technique [0002] When processing key parts such as the valve body, it is necessary to process each end face of the valve body, the channel and the seat mounting seat in the valve body separately. At present, when processing each end face, channel, and valve seat mounting seat in the valve body, when one end face, one end channel and one side valve seat mounting seat are processed, the valve body must be removed from the machine tool, turned around and re-clamped. Process the end face, channel and seat mounting seat of the other end. One of its disadvantages is that the clamping process affects the processing speed of the valve body, and the processing efficiency is low; the second disadvantage is that there is a position error in each clamping, which affects the two end faces of the valve body...
