Embodiment
[0016] Example: see figure 1 , figure 2 , a detection pin for an automobile sheet metal part inspection tool, comprising a hand-held part 1, a detection part 2 and a guide part 3 connected in sequence, the hand-held part 1, the detection part 2 and the guide part 3 are columnar structures arranged coaxially, and decrease in diameter. One side of the hand-held part 1 is a planar structure; this makes it easier to rotate the hand-held part 1 during the detection process. The end of the guide part 3 away from the detection part 2 is tapered; thus, it is faster to insert the guide part 3 into the detection hole on the inspection tool.
[0017] One side of the detection part 2 is provided with a marking needle 4, the axial direction of the marking needle 4 is consistent with the axial direction of the detection part 2, and its needle part is fixedly connected with the end face of the hand-held part 1, and the marking needle 4 The distance between the needle point and the axis l...

The invention discloses a detecting pin for an automobile sheet metal part test tool. The detecting pin comprises a handheld part, a detecting part and a guide part, the handheld part, the detecting part and the guide part are connected in sequence, a line carving needle is arranged on one side of the detecting part, the axial direction of the line carving needle is consistent with that of the detecting part, the needle head of the line carving needle is fixedly connected with the end face of the handheld part, and when the guide part is inserted into a detecting hole in the test tool, the end, away from the handheld part, of the detecting part can penetrate through a sheet metal part to be detected, and the line carving needle can be in contact with the sheet metal part. According to the detecting pin, a kidney-shaped hole in the sheet metal part can be fast detected, detecting speed is high, and precision is high.
Description
technical field [0001] The invention relates to a checking tool, in particular to a testing pin for a checking tool of an automobile sheet metal part. [0002] Background technique [0003] In the process of stamping, welding and other processing of body sheet metal parts, in order to ensure the size matching between parts, it is necessary to monitor the size of these small surfaces on a single part. In the detection process, the sheet metal parts are usually assembled to the corresponding inspection tools, and then the positions of the mounting holes and positioning holes of the sheet metal parts are detected by the detection pins, and the sheet metal parts and the inspection tools are detected by the detection ruler. gap between etc. [0004] Most of the current detection pins have a columnar structure, including a guide part and a detection part arranged coaxially. During detection, the detection pin is inserted into the detection hole on the inspection tool through the...
