Problems solved by technology

[0002] At present, our company's existing roof frame welding fixture adopts the method of temporary positioning blocks according to different models and conditions. On a bottom frame, the on-site measurement and temporary addition and deletion of positioning blocks are carried out on the tooling. This "floor-style" approach , poor positioning accuracy, no clamping device, this practice not only wastes a certain amount of time, but also seriously affects the stability of product quality

Embodiment

[0035] An interchangeable roof frame assembly welding fixture, such as Figure 1~3 As shown, it includes a universal chassis 5 and a tooling assembly composed of a first tooling unit 6 , a second tooling unit 7 , a third tooling unit 8 and a fourth tooling unit 9 fixed on the universal chassis 5 in sequence. The general underframe 5 comprises a frame formed by two parallel beams 51 and several parallel longitudinal beams 52 connected to the two beams 51 at both ends. The bottom of the universal underframe 5 is provided with 12 columns, the crossbeams 51 and the longitudinal beams 52 H-shaped steel with a cross-section of 200mm*200mm*10mm is adopted, and the general underframe 5 is formed by tailor welding. The roof frame assembly 12 is placed on the tooling assembly, and each tooling unit includes a frame formed by connecting several horizontal square tubes and vertical square tubes, wherein the square tubes are high-strength tubes of 60mm*50mm*4mm, such as Figure 6-9 As sho...

Abstract

The invention relates to an exchangeable top cover skeleton welding jig. The exchangeable top cover skeleton welding jig includes a universal under bed; the universal under bed includes two cross beams which are arranged in parallel, and a plurality of parallel longitudinal beams, wherein two ends of the longitudinal beams are connected to the two cross beams; a tooling assembly is fixed on the universal under bed; a top cover skeleton assembly is placed on the tooling assembly; the tooling assembly consists of a plurality of tooling units which are successively fixed on the universal under bed; each tooling unit includes a frame which are formed by connecting a plurality of horizontal square tubes and longitudinal tubes; corresponding top cover skeleton assembly positioning blocks are arranged on the horizontal square tubes and the longitudinal tubes according to different vehicle types; and the tooling units and the universal under bed are accurately positioned through positioning pins, and the tooling units are fixed on the universal under bed through fast clamps. Compared with the prior art, the exchangeable top cover skeleton welding jig can adapt to various types of vehicles at the same time, is convenient in positioning, is fast and accurate, is easy to operate, and can save storage space.

Description

technical field [0001] The invention relates to a welding jig, in particular to a welding jig for an exchangeable roof frame assembly. Background technique [0002] At present, our company's existing roof frame welding fixture adopts the method of temporary positioning blocks according to different models and conditions. On a bottom frame, the on-site measurement and temporary addition and deletion of positioning blocks are carried out on the tooling. This "floor-style" approach , Poor positioning accuracy and no clamping device, this method not only wastes a certain amount of time, but also seriously affects the stability of product quality. Contents of the invention [0003] The object of the present invention is to provide an exchangeable roof frame assembly welding jig that can adapt to several vehicle types at the same time, is convenient in positioning, fast and accurate, easy to operate and saves storage space in order to overcome the above-mentioned defects in the ...
