Problems solved by technology

[0002] At present, various automobile air-conditioning manufacturers have the following problems in measuring the position and coaxiality of the heading on the pipeline: only the three-coordinate measuring instrument can accurately measure the position and coaxiality of the pipeline, but through the three-coordinate Inspections are time consuming and costly
Therefore, this method can only be tested on test pieces, and it is not feasible for batch products.

Abstract

The invention discloses a movable upset head check block structure for a check tool, which is characterized in that the end of a reference part is provided with a circular table, the other end of the movable part is provided with a circular hole, the circular table is arranged in the circular hole, and a circular check ring is arranged at the opening of the circular hole. The invention has the advantages of effectively and accurately checking the displacement and the coaxiality of the upset head, saving operation time, increasing yield and greatly reducing cost; the integral structure has reasonable design and good practicability and is easy for popularization and application.

Description

Technical field: [0001] The invention relates to the technical field of the design of inspection fixtures for automobile air-conditioning pipelines, in particular to a movable heading inspection block structure for inspection fixtures, and in particular to its mechanical connection structure. Background technique: [0002] At present, various automobile air-conditioning manufacturers have the following problems in measuring the position and coaxiality of the heading on the pipeline: only the three-coordinate measuring instrument can accurately measure the position and coaxiality of the pipeline, but through the three-coordinate Inspections are time-consuming and costly. Therefore, this method can only be tested on test pieces, and it is not feasible for batch products. [0003] Such as figure 1 As shown in , the existing inspection tool has an integral structure with the upper heading sleeve, and a hole is provided at one end. Invention content: [0004] The purpose of ...
