Description

Technical Field

[0001] The invention relates to the technical field of automobile parts detection, and in particular to an automobile nut plate convex point detection device. Background Art

[0002] The automotive nut plate is a special mechanical part, mainly used to maintain the tightness of the bolt connection. It is usually designed as a steel plate welded part, shaped like a round pancake, so it is also called a spring washer or butter clamp. The automotive nut plate has a certain elasticity and friction, which can evenly distribute the force of the screw to the contact surface, make the metal surfaces fit each other, and prevent loosening through its own locking effect.

[0003] In order to ensure the safety and reliability of automobile nut plates, it is necessary to conduct a certain amount of random inspections on the produced nut plates. Before inspecting the nut plates, the staff is required to assemble the bolts to the nut plates and observe whether the nut plates are damaged by manual knocking to determine whether the nut plates are qualified.
