Welding fixture for bracing steel wire in the frame of six-point seat cushion

Abstract

The invention discloses a brace-shaped steel wire welding fixture in a sextant seat cushion skeleton. The brace-shaped steel wire welding fixture includes a bottom plate, positioning mechanisms, lifting clamping seats, first pressing blocks, second pressing blocks, a clamping block and a seat side brace-shaped steel wire positioning block, wherein the positioning mechanism, the lifting clamping seat, the first pressing blocks, the second pressing blocks, the clamping block and the seat side brace-shaped steel wire positioning block are arranged on the bottom plate. The positioning mechanisms are distributed evenly along a frame pipe and used for supporting and positioning. The lifting clamping seats are uniformly distributed along the lower side of a seat front brace-shaped steel wire andused for lifting and limiting. The first pressing blocks are located the front side and the right side of the seat front brace-shaped steel wire and presses the seat front brace-shaped steel wire towards the frame pipe. The seat side brace-shaped steel wire positioning block is located at the front end and the back end of a seat side brace-shaped steel wire and used for supporting and limiting. The clamping block corresponds to the seat front brace-shaped steel wire at the left side and the seat side brace-shaped steel wire, and the seat front brace-shaped steel wire and the seat side brace-shaped steel wire are pressed synchronously. By means of the brace-shaped steel wire welding fixture, each part is independently positioned and clamped, positions are reasonably distributed, stress balance is ensured, positioning of the steel wires is facilitated, the bracing effect after welding of the steel wires is ensured, meanwhile, the accuracy of the hole positioning is ensured through a holepositioning connecting arm and a connecting bracket.

Description

technical field [0001] The invention belongs to the technical field of seat frame welding, and in particular relates to a support-shaped steel wire welding fixture in a seat cushion frame of a six-point seat. Background technique [0002] There are many kinds of steel wires welded in the frame of the six-point seat cushion, such as figure 2 Shown: It includes the frame tube, the seat front brace steel wire located on the front side of the frame tube, the seat side brace steel wire located on the left side of the frame tube, and the connecting arms located at both ends of the rear side of the frame tube, and various steel wires are prone to deformation , it is not easy to position and weld, and at the same time, it is necessary to ensure that the positioning of the connecting arm and the frame tube is accurate, the positioning of the connecting hole on the connecting arm is accurate, and the quality of later assembly is ensured. Therefore, the difficulty of welding the entire...
