Abstract

The invention provides a processing method of a gauge head outline of a special-shaped hole air gauge, wherein the special-shaped hole air gauge head is an irregular cylinder, the outline thereof is formed by n-R arc sections, an external circle phi and an external circle phi 1, wherein the top points of n-R each arc section can form the external circle phi, and can divide the external circle phi 1 into n sections. The processing steps comprise blanking, length processing, external circle processing, external circle phi coarse grinding, end surface coarse grinding, line marking, internal boring, heat treatment, hole grinding, external circle grinding, end surface grinding, assembling and gauge head outline processing and the like. The method can solve the problem of great processing difficulty of the gauge head outline of the special-shaped hole air gauge, thereby guaranteeing the normal processing of the gauge head outline of the special-shaped hole air gauge.

Description

technical field [0001] The processing method belongs to the field of measuring tool processing. It specifically relates to the processing of the shape of the measuring head of the pneumatic gauge with special-shaped holes. Background technique [0002] Pneumatic gauge is a kind of measuring tool with wide applicability and can measure the outer diameter and inner diameter of products. The pneumatic measuring head has a simple shape and is easy to process, while the shaped hole pneumatic measuring head has a special shape and structure and is difficult to process. It can be processed with a general pneumatic measuring head. Technology has been unable to process the shape of the measuring head of the pneumatic gauge with special-shaped holes. Contents of the invention [0003] The invention proposes a method for processing the profile of a pneumatic gauge probe with a special-shaped hole, aiming at solving the problem of difficulty in machining the profile of the pneumatic ...
