Description

Technical Field

[0001] The utility model relates to the technical field of brake piece steel back detection, in particular to a comprehensive inspection tool for quickly detecting the full length and thickness of a dovetail type brake piece steel back. Background Art

[0002] The steel back of the dovetail type brake pad needs to be inspected for full length and thickness after processing. The previous process was: full length inspection using a digital caliper, thickness inspection using a micrometer. Due to the large batch size of this product, the efficiency was too slow during the processing and final inspection, which seriously affected the production and delivery efficiency. In order to solve the above problems, a comprehensive inspection fixture for quickly detecting the full length and thickness of the steel back of the dovetail type brake pad was proposed. Utility Model Content

[0003] According to the above existing technical problems, the utility model provides a comprehensive inspection tool for quickly detecting the full length and thickness of the steel back of a dovetail type brake pad, which is characterized by comprising a dial indicator, a locking block, a reference positioning surface, a fixture bottom plate, a stop gauge block, a through gauge block, a locking block is arranged on the fixture bottom plate, a reference positioning surface is arranged on the fixture bottom plate, a locking block is arranged on the reference positioning surface, a dial indicator is arranged on the locking block, a stop gauge block is arranged on the fixture bottom plate, and a through gauge block is arranged in front of the stop gauge block;

[0004] Furthermore, the surface of the fixture bottom plate has a groove, the reference positioning surface is located on the upper surface of the groove, there are a plurality of locking blocks, which are respectively fixed on the upper surface of the fixture bottom plate, and each locking block is provided with a dial indicator;

[0005] Furthermore, the stop gauge block and the through gauge block are fixedly arranged on one side of the fixture bottom plate, and the stop gauge block and the through gauge block are located below the locking block.

[0006] Beneficial effects of the utility model:

[0007] The utility model is fixedly connected with the fixture bottom plate by bolts, and the thickness dimension value is adjusted. The detection piece is placed in the groove of the fixture bottom plate, and the small head end of the detection piece slides backward against the reference positioning surface. When it can pass through the through gauge block but not the stop gauge block, it means that the product thickness dimension is within the required range of the drawing; when the detection piece cannot pass through the stop gauge block, the values ​​of several dial indicators can be checked. If they are within the requirements of the drawing, it can be shown that the thickness dimension meets the requirements of the drawing. Through repeated inspections and small-batch inspections of parts using the inspection fixture in the production workshop, it is found that it is 3-4 times faster than the previous inspection using digital calipers and micrometers. At the same time, the inspection fixture is promoted to the final inspection use. Through current verification, the final inspection personnel are reduced from 3 people to 2 people to inspect the process. BRIEF DESCRIPTION OF THE DRAWINGS
