Abstract

The invention provides a positioning device and a buckling positioning method of a longitudinal beam, relates to the technical field of vehicle fittings, and solves the problems of incapability of guaranteeing the buckling precision and easy generation of verification error caused by using a visual inspection mode for performing the buckling verification for inner and outer plates in the prior art. The positioning device comprises a detector matched and connected with a part, wherein at least two positioning grooves are formed in the detector. The positioning device further comprises dowel pins; one ends of the dowel pins are fixed in the positioning grooves, and the other ends are free ends; and the dowel pins are used for positioning the position of the part corresponding to the detector. The positioning device is mainly applied to vehicles.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a positioning device and a fastening and positioning method for longitudinal beams. Background technique [0002] The frame, as an accessory that supports and connects the various assemblies of the automobile, has sufficient strength and rigidity to withstand the load of the automobile and keep the assemblies in a relatively correct position. [0003] Among them, taking the side beam frame as an example, it is mainly welded by two long longitudinal beams and several cross beams to ensure the rigidity of the vehicle body. Specifically, the longitudinal beam structure includes matching inner and outer panels. Usually, the inner and outer panels are manufactured separately using molds, and welded by fastening the inner and outer panels to form the longitudinal beam structure. . In actual application, in order to ensure the fastening clearance of the inner and outer pan...
