Description

Jig for checking automobile parts Technical Field The utility model relates to the technical field of automobile accessory inspection, in particular to a jig for automobile accessory inspection. Background The automobile parts are all units forming the whole automobile and are a product serving the automobile, and after the automobile parts are produced, all the parts are assembled, so that the automobile parts need to be detected in advance before assembly in order to ensure the smooth assembly of the parts and the safety and stability after assembly. The automobile accessory detection jig comprises a mounting plate and further comprises two linear moving assemblies, wherein two right aligned rectangular grooves are formed in the surface of the mounting plate, and the whole of the two linear moving assemblies are respectively arranged in the rectangular grooves. The automobile accessory detection jig selects a connecting rod which is qualified after inspection, then adjusts the distance between two moving blocks through two linear moving assemblies, enables the center distance between the two moving blocks to be consistent with the center distance of the connecting rod, uses two centering assemblies, adjusts the distance between two first ejector rods and the distance between two second ejector rods, enables the two first ejector rods and the two second ejector rods to be respectively positioned in two round holes of the connecting rod through the adjustment and contact with the inner wall of the round hole, places each connecting rod with undetected connecting rods for the same batch of connecting rods, and is qualified if the connecting rods can be smooth, otherwise, is unqualified.
