Six-point seat back frame assembly welding fixture

Abstract

The invention discloses a welding clamp for a backrest frame assembly of a sixty-percent seat. The welding clamp comprises a base, first positioning parts, a second positioning part, third positioningparts, a fourth positioning part and fifth positioning parts, wherein the first positioning parts are distributed along an upper transverse pipe, a right support plate, a lower transverse pipe and amiddle longitudinal plate and are fixedly arranged on the base, the second positioning part is arranged on the left part of the base and is located on the outer side of a left square pipe, the third positioning parts correspond to a headrest pipe and are distributed at the upper part of the base, the fourth positioning part is arranged right opposite to an unlocking box mounting support at the right upper corner, and the fifth positioning parts correspond to a left side plate and a right side plate, are arranged on the left lower part and the right lower part of the base and are located on theouter side of the corresponding left side plate and the outer side of the corresponding right side plate correspondingly. The welding clamp for the backrest frame assembly of the sixty-percent seat has the advantages that multiple parts can be synchronously welded at a time, the operation process can be simpler, a backrest frame can be welded by only one clamp, meanwhile, a plurality of positionpoints can be positioned, and positioning can be more accurate.

Description

technical field [0001] The invention belongs to the technical field of seat back welding, and in particular relates to a welding jig for a six-point seat back frame assembly. Background technique [0002] Six-point seat back frame such as figure 1 with 3 Shown: including the upper horizontal tube, the lower horizontal tube, the left square tube, the right bracket plate, the left and right side plates, the middle longitudinal plate, the armrest mounting plate and the unlocking box mounting bracket in the upper right corner. Welding, because there are many parts, and the welding of the seat back frame in the prior art is usually the welding of local parts one by one, but this will increase the welding process, each process requires a welding fixture, multiple welding operations The process is complicated. Once the intermediate link is welded inaccurately, it is easy to cause the failure of the subsequent process, resulting in the dislocation of the positioning holes, and aff...

[0002] Six-point seat back frame such as figure 1 and 3 Shown: including the upper horizontal tube, the lower horizontal tube, the left square tube, the right bracket plate, the left and right side plates, the middle longitudinal plate, the armrest mounting plate and the unlocking box mounting bracket in the upper right corner. Welding, because there are many parts, and the welding of the seat back frame in the prior art is usually the welding of local parts one by one, but this will increase the welding process, each process requires a welding fixture, multiple welding operations The process is complicated. Once the intermediate link is welded inaccurately, it will easily lead to the failure of the subsequent process, resulting in the misalignment of the positioning holes and affecting the positioning and installation of the assembly structure.
