Description

Technical Field

[0001] The utility model relates to the field of production and detection of wiring harness terminals, in particular to a wiring harness terminal pin flatness inspection tool. Background Art

[0002] With the rapid development of the automobile industry, traditional fuel vehicles are gradually moving closer to new energy vehicles. In the process of automobile production and assembly, several or dozens of automobile wiring harnesses are commonly used. Especially in the field of new energy automobile production, there are hundreds of automobile wiring harnesses. These different wiring harnesses connect different electronic devices to achieve different functions. Therefore, the connection accuracy of automobile wiring harness terminals is extremely high.

[0003] Announcement No. CN 216081287 U discloses a wiring harness terminal pin flatness inspection fixture. The angle of the inspection slide and the position of the adjustment block are adjusted according to the specifications of the terminal. When adjusting the angle of the inspection slide, the mouth-shaped adjustment block is slid up and down to a suitable position by rotating the screw rod. Under the action of the mouth-shaped adjustment block, the guide rod will also slide to a suitable position in the arc-shaped slide groove; when adjusting the position of the adjustment block, the adjustment block is slid to a suitable position by loosening the bolt assembly and then tightening the bolt assembly. The terminal slides from the upper end of the inspection slide along the fixed block and the adjustment baffle. If the terminal is stuck or falls slowly, it is a defective product. If the terminal can fall smoothly, it is a qualified product. However, once a defective product is stuck on the inspection fixture in the above device, the inspection fixture needs to be manually disassembled and removed. After being removed and reset, the accuracy of the inspection fixture needs to be readjusted, which is time-consuming and labor-intensive, greatly affecting the inspection efficiency.
