Clamp for longitudinal beam of rear floor slab of automobile

Abstract

The invention discloses a clamp for of a longitudinal beam of a rear floor slab of an automobile, comprising support legs and a support table fixed on the support legs, wherein a sliding and clamping device and a plurality of positioning and clamping devices are arranged on the support table, wherein the sliding and clamping device is used for fixing parts to be welded on the longitudinal beam of the rear floor slab; the positioning and clamping devices are used for fixing the longitudinal beam of the rear floor slab and the parts to be welded on the longitudinal beam of the rear floor slab; each positioning and clamping device comprises a first angle seat, a fist template fixedly connected with the first angle seat and a clamping arm which is rotationally matched with the first template; first positioning pins which are matched with mounting hole sites on the longitudinal beam of the rear floor slab are arranged on the at least one first angle seat in the positioning and clamping device; the sliding and clamping device comprises a second angle seat and a second template which is fixedly connected with the second angle seat; and second positioning pins matched with the mounting hole sites of the parts to be welded on the longitudinal beam of the rear floor slab are arranged on the second template. According to the clamp, clamping and welding the longitudinal beam of the rear floor slab of the automobile can be realized, the positioning and welding the longitudinal beam of the rear floor slab of the automobile are effectively solved and the welded consistency is ensured.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp for rear floor longitudinal beams of an automobile. Background technique [0002] In the car body structure, the underbody assembly is composed of three parts, the front cabin, the front floor and the rear floor, and there are longitudinal beams on the left and right sides under these three parts. The longitudinal beams of the three parts are organically combined and welded. As a result, it carries the main weight of the vehicle. Among them, the front cabin longitudinal beam is equipped with the front axle and front shock absorber, and the rear axle and rear shock absorber are respectively installed on the left and right side longitudinal beams of the rear floor. More specifically, the rear swing arm support assembly, the rear floor longitudinal beam reinforcement plate assembly, the rear shock absorber seat, the rear muffler installation hook assembly and the rear section of the rear floor lo...

Problems solved by technology

[0004] At present, the jig used on site uses the commonly used flip positioning to locate the installation hole of the rear axle. Although this positioning mechanism is simple and easy to operate, many welding jigs use this structure, but because it is a flip mechanism, the movement track is a section. Arc, so when the positioning pin is in contact with the positioning hole (that is, the mounting hole of the rear axle), there is always a deviation, that is, when positioning, the positioning pin and the positioning hole are vertical, and when the positioning pin is opened, there will be a gap between the positioning pin and the positioning hole. The holes interfere slightly, which makes it difficult to guarantee the consistency of the mounting holes after welding
