Hanging spot welding clamp for back plate of six-branch seat backrest

Abstract

The invention discloses a hanging spot welding clamp for a back plate of a six-branch seat backrest. The hanging spot welding clamp comprises a base and supporting clamps, wherein the supporting clamps are arranged at edges of the base and are used for supporting and clamping a square framework and the back plate; the middle part of the base is provided with a positioning support block for hooking the framework by an anchor hook; shaft supporting blocks are arranged on the positions, corresponding to hinged shafts on two sides of the square framework, of the base, and shaft limiting grooves are formed in the top surfaces of the shaft supporting blocks; the position, corresponding to a head tube of the square framework, of the base is provided with a positioning bolt; a vertical upward positioning pin is arranged on the position, corresponding to a hole position of the upper surface of the back plate, of the base; and the supporting clamps, the positioning support block, a shaft supporting blocks, the positioning bolt and the positioning pin are installed on the heightened L-shaped supporting frames, and the supporting frames are fixedly connected with the base. According to the hanging spot welding clamp for the back plate of the six-branch seat backrest, the supporting clamps are used for clamping and fixing multiple directions, multiple spots like the hole, the head tube, the hinged shafts are positioned, so that positioning is more accurate, fixation and stability are realized, and the hanging spot welding clamp effectively meets the requirements of welding space of thewelding gun.

Description

technical field [0001] The invention belongs to the technical field of seat backrest backboard welding, and in particular relates to a six-point seat backrest backboard suspension spot welding fixture. Background technique [0002] Six-point seat backrest figure 2 and 3 As shown: it includes a square frame and a back plate covered on the square frame, wherein the connection between the square frame and the back plate is evenly distributed with welded parts. When the square frame faces downward, the welding space and station requirements are relatively high. Therefore, a fixture that can not only meet the welding station requirements, but also accurately position the square frame and the backplane is needed. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a six-point seat backrest and back panel suspension spot welding fixture, which is accurate and stable in positioning and can effectiv...
