Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning pipeline production and manufacturing, in particular to a pipeline assembly inspection tool. Background Art

[0002] Automobile air-conditioning pipelines are pipeline assemblies used to connect the various components of automobile air-conditioning. In production and manufacturing, in order to control the life quality of the pipelines, reduce weight and reduce costs, the pipeline materials are often designed to be aluminum alloy pipes. Therefore, once the pipeline assembly is welded and manufactured, it will be difficult to correct the deformation. Therefore, inspection fixtures are required before the pipeline assembly leaves the factory to reduce the probability of unqualified products flowing into the production line and causing assembly difficulties.

[0003] In the related art, reference can be made to the Chinese utility model patent with authorization announcement number CN219455162U, which discloses an automobile air-conditioning electronic valve and pipeline assembly inspection tool, including a base, a plurality of pipeline support seats arranged on the base and arranged in sequence along the extension direction of the air-conditioning pipeline, an expansion valve pressure plate detection assembly arranged at one end of the air-conditioning pipeline, and an electronic valve detection assembly arranged at the other end of the air-conditioning pipeline. A first groove is provided on the pipeline support seat, and the axis of the pipeline section of the air-conditioning pipeline located in the first groove is parallel to the groove bottom surface of the first groove corresponding thereto. During inspection, the automobile air-conditioning electronic valve and pipeline assembly can be placed on the inspection tool.

[0004] This inspection tool can only inspect a single pipe at a time. When the pipeline assembly includes multiple pipes, it needs to be reused multiple times. However, the sizes and directions of the multiple pipes are not completely consistent, and there are pipe clamps, pressure plates, connecting seats, etc. connecting the multiple pipes. It is impossible to accurately detect and locate the relevant dimensions with the same inspection tool, and a measuring ruler, coordinate measuring machine, etc. are also required for auxiliary inspection, thereby reducing the inspection efficiency of the automobile air-conditioning pipeline assembly.
