Bearing type and non-bearing type body-in-white lower vehicle body mixed flow tool and method

Abstract

The invention discloses a bearing type and non-bearing type body-in-white lower vehicle body mixed flow tool and method. The mixed flow tool comprises a split type clamp mounting plate, a front longitudinal beam positioning unit, a front wall assembly positioning unit, a non-bearing type rear wall translation gable wall, a rear wheel cover sliding table positioning unit, a bearing type rear wall translation gable wall and a control system. According to the vehicle body types of bearing type and non-bearing type body-in-white lower vehicle bodies, the control system controls the front longitudinal beam positioning unit, the front wall assembly positioning unit, the rear wheel cover sliding table positioning unit and the bearing type rear wall translation gable wall to position and assemble the bearing type body-in-white lower vehicle body; or the front wall assembly positioning unit and the non-bearing type rear wall translation gable wall are used for positioning and assembling the non-bearing type body-in-white lower vehicle body. The bearing type and non-bearing type body-in-white lower vehicle body mixed flow tool is novel in thought, ingenious in structure, high in automation degree and capable of meeting the mixed flow production requirements of various bearing type and non-bearing type military off-road vehicle body-in-white lower vehicle bodies.

Description

technical field [0001] The invention belongs to the technical field of military off-road vehicle body-in-white manufacturing technology, and more specifically relates to a load-bearing and non-load-bearing type mixed-flow tooling and method for the body-in-white body. Background technique [0002] In the field of automobiles, the body can be divided into two series of load-bearing body and non-load-bearing body. Each series can be divided into single-row cars, one-and-a-half-row cars, double-row cars, 6-person cars, and 10-person cars according to the length of the wheelbase. type and many other varieties. [0003] The lower body of the military off-road vehicle body-in-white is quite different from ordinary passenger cars or trucks. Due to the functional design of the body structure and the needs of the manufacturing process, the lower body of the body-in-white is composed of the front wall assembly (including the cabin, front floor, etc.) , middle floor), rear wheel housi...

Problems solved by technology

[0003]The lower body of the military off-road vehicle body-in-white is quite different from that of ordinary passenger cars or trucks. Due to the functional design of the body structure and the needs of manufacturing processes, white The underbody body consists of a front wall assembly (including the engine room, front floor, and middle floor), a rear wheelhouse assembly (including the rear floor, but only for the load-bearing body), and a rear wall assembly. Ordinary passenger cars or The truck underbody is mainly composed of the engine room, front floor, and rear floor; due to the large difference in the structure of the load-bearing and non-load-bearing body-in-white underbody, at present, in the field of passenger car or truck body manufacturing, independent production lines are usually established. Non-collinear production; and because the body-in-white body of military off-road vehicles is quite different from ordinary passenger cars or trucks, the production line of ordinary passenger cars or trucks is not suitable for the body-in-white of military off-road vehicles
