Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a detection pin for detecting automobile sheet metal parts. Background Art

[0002] With the continuous development of the automobile industry, automobile manufacturers have continuously improved their requirements for automobile quality. In order to control product quality, they will test the contours of automobile sheet metal parts. However, in actual production, it is very troublesome to measure large quantities of products one by one using measuring tools (such as contour measuring instruments, three-coordinate measuring instruments and other precise measuring tools). Qualified products have a measurement range, and all products within this range are qualified. The test pin is a kind of gauge, which is used as a measurement standard for large-scale inspection, so the qualified products are generally measured by the test pin.

[0003] During the inspection, the automotive sheet metal parts are usually placed in a special inspection fixture (processed according to the shape of the sheet metal parts and with a standard gap), and then the pass of the go gauge and the stop gauge in the inspection pin are used to determine whether the profile of the automotive sheet metal parts meets the standard. The go gauge is the lower limit of the allowable deviation, while the stop gauge is the upper limit of the allowable deviation.

[0004] However, the go gauge and the stop gauge in the existing detection pin are mostly connected to the handle by threads, which is inconvenient to replace different go gauges and stop gauges (different parts require go gauges and stop gauges of different specifications); and the threaded connection method may become loose or even unscrewed and fall off during the detection process, affecting the detection. In addition, since there are many specifications of parts that need to be detected, there are also many specifications of go gauges and stop gauges. How to avoid losing them is also a problem that needs to be solved in this field. Utility Model Content
