Work fixture for sand blasting and spraying of cylinder liners

Abstract

A work fixture for sand blasting and spraying of cylinder liners comprises a base, a connecting rod and a tightly-pressing disk; one end of the connecting rod is fixedly connected with one end face of the base, the other end of the connecting rod is in threaded connection with on end face of the tightly-pressing disk, and the connecting rod is provided with a group of limiting disks in a penetration mode; one side of the base and one same-direction side of each limiting disk are each provided with a cylindrical protective barrel, the base and each limiting disk are each provided with a circular annular positioning groove located on the inner side of a limiting ring, and the other side of the limiting disk and one same-direction side of the tightly-pressing disk are each provided with a circular positioning disk; the central lines of the connecting rod, the protective barrels, the positioning grooves and the positioning disks coincide. The work fixture can stabilize the product quality, improves the production efficiency, reduces the labor intensity of workers, is easy for workers to operate, and has no installation error, so as to ensure that a protection area of a cylinder is not sandblasted and sprayed.

Description

technical field [0001] The invention belongs to the technical field of cylinder liner processing and production, and in particular relates to a tooling fixture for sandblasting and spraying of a cylinder liner. Background technique [0002] At present, the sandblasting and spraying of the outer circle of the cylinder liner is carried out with a single operation, which has low production efficiency, high labor intensity, difficult protection of the area required to be protected, and unstable quality. Now because the follow-up processing of the cylinder liner has higher and higher requirements for sandblasting and spraying, the existing single fixture for sandblasting and spraying can no longer meet the needs of mass production of products. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a cylinder liner sandblasting and spraying jig with high production efficiency, low labor intensity, improved product q...

AI Technical Summary

Problems solved by technology

[0002] At present, the sandblasting and spraying of the outer circle of the cylinder liner is carried out with a single operation, the production efficiency is low, the labor intensity is high, and the protection of the area required to be protected is difficult and the quality is unstable.

Now because the subsequent processing of the cylinder liner has higher and higher requirements for sandblasting and spraying, the existing single fixture for sandblasting and spraying can no longer meet the needs of mass production of products
