Problems solved by technology

It needs to be fixed by welding fixtures during welding, but the traditional welding fixtures are all corresponding to the car floor of a single model. This kind of single welding fixture is useless after the model is upgraded, and the corresponding welding fixture needs to be remade. thereby increasing production costs

Embodiment

[0015] Such as figure 1 As shown, a general welding jig for producing the base plate of the prototype car and its derivative models is composed of three parts: a fixed base 1, a switching mechanism and a positioning mechanism. Wherein, the switching mechanism includes a linear cylinder 2 arranged on a fixed base 1, a guide rail chute assembly 3 and two switching limit blocks 4, and the positioning mechanism includes a cylinder fixing bracket 5 and a positioning cylinder 6 arranged on the cylinder fixing bracket 5 .

[0016] The concrete structure of guide rail chute assembly 3 is as follows: figure 2 As shown, a double guide rail chute mobile unit is adopted, including two guide rails 31 arranged in parallel and a slider 32 arranged on the guide rail 31. The slider 31 and the guide rail 32 are provided with mutually matching chute, so that the slider 31 can slide along guide rail 32. The cylinder fixing bracket 5 is fixedly connected with two slide blocks 31 located on the...

Abstract

The invention relates to a general welding clamp for producing base plates of a prototype vehicle and derived vehicle types of the prototype vehicle. The general welding clamp comprises a fixed base, a switching mechanism and a positioning mechanism, wherein the switching mechanism comprises a linear air cylinder, a guide rail sliding groove assembly and two switching limiting blocks, which are arranged on the fixed base; the positioning mechanism comprises an air cylinder fixing bracket and a positioning air cylinder which is arranged on the air cylinder fixing bracket; the air cylinder fixing bracket is movably erected on the guide rail sliding groove assembly and is driven by the linear air cylinder to move along the guide rail sliding groove assembly; the two switching limiting blocks are positioned at two ends of the guide rail sliding groove assembly respectively and are used for limiting the moving position of the air cylinder fixing bracket on the guide rail sliding groove assembly. Compared with the prior art, the general welding clamp for producing the base plates of the prototype vehicle and the derived vehicle types of the prototype vehicle has the advantages that the generality of the derived vehicle types can be achieved by switching the positions of parts of the welding clamp; the production cost is reduced.

Description

technical field [0001] The invention relates to a welding jig for the bottom plate of an automobile, in particular to a universal welding jig for producing the bottom plate of a prototype car and its derived models. Background technique [0002] At present, many automobile manufacturers need to weld the automobile floor during the production process. It needs to be fixed by welding fixtures during welding, but the traditional welding fixtures are all corresponding to the car floor of a single model. This kind of single welding fixture has no use value after the model is upgraded, and the corresponding welding fixture needs to be remade. Thereby increasing the production cost. Contents of the invention [0003] The object of the present invention is to provide a universal welding jig for producing the base plate of the prototype car and its derived models in order to overcome the above-mentioned defects in the prior art. performance, saving production costs. [0004] The...
