Description

Quick-change structure of test fixture Technical Field The utility model relates to the technical field of mold detection equipment, in particular to a quick-change structure of a test fixture. Background In the automobile production process, some detection and test are needed to be carried out on the produced parts so as to determine whether the national standard and the use standard are met, which is an indispensable step in the production process. In the detection process, the workpiece to be detected needs to be temporarily fixed, so that the workpiece is prevented from being damaged when falling onto the ground in the detection process, the detection efficiency is not only influenced, but also loss is possibly paid by detection personnel, and therefore, the clamp structure while the detection personnel is still very important; Meanwhile, when the single clamp is used for coping with various complex workpieces and accessories, multiple faces are difficult to consider, the clamp can shake in a small range after being fixed, and the clamp can deviate from a detection position easily when a detection person works, so that the structure that the main clamp comprises the sub-clamp is designed, the inner ring clamp is not fixed after the outer ring clamp is fixed, the clamp can be flexibly disassembled for coping with different types of detection workpieces, other clamps with the same type can be conveniently and quickly replaced, and the quick replacement structure of the test clamp is provided based on the design conception. Disclosure of utility model The utility model aims to provide a quick-change structure of a test fixture, which aims to solve the problems in the prior art. In order to achieve the aim, the utility model provides the technical scheme that the quick-change structure of the test fixture comprises a disc, wherein a chute is transversely formed in the middle of the front side of the disc; The right side of the disc is provided with a motor, the left side transmission end of the motor is connected with a threaded rod, the threaded rod transversely penetrates and is inserted into an inner cavity of the disc leftwards and is positioned at the rear side of the chute, two outer ring clamps are symmetrically arranged at two sides of the front side of the disc and are butted semicircular clamps, inner ring grooves which can be in and out are formed in inner cavities at the opposite sides of the outer ring clamps, the inner ring clamps are arranged in the inner ring grooves, symmetrical outer ring clamp fixing blocks are respectively fixed on two side walls which do not obstruct the inlet and the outlet of the inner ring grooves at the middle parts of the opposite sides of the outer ring clamps, mounting blocks are respectively arranged at the middle parts of the opposite sides of the two outer ring clamps, the rear side of the mounting blocks is an integrally formed mounting block base, threaded holes are respectively formed in the mounting block base in a penetrating way, the mounting block base is backwards and is in a butted with the chute, the threaded rods are respectively connected with the threaded rod in a threaded way, the left side and the threads and the right side of the threaded rod are opposite, the middle parts of the opposite sides of the mounting block are fixedly provided with a telescopic motor through a support frame, the two opposite side walls of the motor, the two opposite side clamps are respectively provided with telescopic rods, and the telescopic rods are respectively connected with the inner ring and the telescopic rods extend to the inner ring; Preferably, the top and the bottom of the motor are welded with fixing frames, and the fixing frames are fixed on the side walls of the discs leftwards.
