Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tool technology, specifically to a conversion mechanism for detecting the positional accuracy of holes and the contour accuracy of peripheral surfaces in products. Background Technology

[0002] Currently, automotive inspection fixtures primarily use positional inspection pins and sleeves to inspect welded nuts and studs. However, when it is necessary to inspect the welded surface simultaneously, most fixtures use a method that combines the inspection gap with a go / no-go gauge. But as product measurement requirements increase, traditional inspection fixtures cannot meet the need to obtain the actual deviation value of the welded surface during the production process. This mechanism, through ingenious design, optimizes the originally limited measurement space by combining the positional inspection pin with the dial indicator mechanism for measuring the surface contour, thereby achieving quantitative detection of the deviation value of the welded surface contour. Utility Model Content

[0003] In view of the problems existing in the above-mentioned automotive inspection tools, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a conversion mechanism for detecting the positional accuracy of holes and the contour accuracy of circumferential surfaces in a product, thereby solving the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conversion mechanism for detecting the positional accuracy and circumferential surface contour of a product hole includes a base plate and a heightening support. The heightening support is fixedly mounted on the upper surface of the base plate. Multiple positioning supports are sequentially arranged from left to right on one side of the upper surface of the heightening support. A first detection support is disposed inside the middle positioning support, and a first detection pin is disposed on the front side of the first detection support. Multiple second detection supports are sequentially arranged from left to right on the upper surface of the heightening support, away from the positioning supports. A rotating column is rotatably mounted inside each of the multiple second detection supports. A dial indicator block is fixedly mounted on the side of the second detection support away from the first detection support. A dial indicator is mounted on the side of the dial indicator block away from the second detection support. The detection head of the dial indicator abuts against one end of the rotating column. A second detection pin is disposed on the end of the rotating column away from the dial indicator. A limit mechanism is disposed on the upper surface of the base plate, away from the second detection supports.

[0007] Preferably, the limiting mechanism includes a clamp seat and a pressure head. The supplementary support has multiple mounting slots on the side near the second detection support. The clamp seats are fixedly installed inside the corresponding mounting slots. A clamp is installed on the upper side of the clamp seats. A threaded rod is threaded on the side of the clamp near the first detection support. The pressure head is fixedly installed at the end of the threaded rod away from the clamp.

[0011] Preferably, handles are provided on both sides of the upper surface of the base plate.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
