Jig for machining cylinder hole and bearing hole of valve body

Abstract

The invention discloses a jig for processing the cylinder hole and bearing hole of a valve body, which includes an indexing plate, a rotating tailstock and a transverse carrier plate; one end of the transverse carrier plate is provided with a positioning device, and the positioning device includes a positioning frame , the positioning frame is respectively provided with a locking mechanism at the upper boss and the lower boss on the side wall of the valve body, and the upper boss and the lower boss on the side wall of the valve body are respectively locked on the corresponding locking mechanism; The other end of the transverse carrier plate is provided with a profiling clamping device, the profiling clamping device includes a support seat, a profiling plate and a driver, the driver is fixed on the support seat, the profiling plate is connected with the pushing end of the driver, and is formed by The actuator drives the clamp on the side wall of the valve body. The jig of the present invention can realize the process of processing the cylinder hole and the bearing hole simultaneously on the NC milling machine in one clamping, avoid the error of multiple clamping, ensure the verticality requirements of the cylinder hole and the bearing hole, and improve the product quality and production efficiency. Significantly increased.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a jig for processing cylinder holes and bearing holes of a valve body. Background technique [0002] Such as figure 1 As shown, the processing technology of the cylinder hole 02, the end surface 03 and the vertical bearing hole 04 of the valve body 01 is processed separately. The traditional processing technology is as follows: Process 1, use the cylinder hole blank of the valve body to position the one end face and the cylinder hole at one end of the car. Process 2, reversely locate the other end face and cylinder hole of the car with the processed cylinder bore and end face. Step 3: Put the tooling on the NC milling machine, and process the vertical bearing hole with the cylinder hole and end face positioned. This kind of processing process has many steps, and it also needs to use CNC lathe and CNC milling machine at the same time and clamp it multiple times. It cannot g...

Problems solved by technology

This kind of processing process has many steps, and the CNC lathe and CNC milling machine must be used at the same time and clamped multiple times. The verticality requirements of the cylinder hole and the bearing hole cannot be guaranteed, and the production efficiency is low.
