Six-point seat cushion skeleton welding fixture

Abstract

The invention discloses a welding clamp for a cushion frame of a sixty-percent seat. The welding clamp is characterized by comprising a base plate used for placing parts of the cushion frame of the seat; and a frame pipe positioning mechanism, a seat front supporting steel wire positioning mechanism, a connecting arm positioning mechanism and a connecting support hole positioning base are arrangedon the base plate. The welding clamp for the cushion frame of the sixty-percent seat has the advantages that the parts can be independently positioned and clamped, the positions are reasonably distributed, the stress balance can be guaranteed, steel wires can be conveniently positioned, the supporting effect after the steel wires are welded can be guaranteed, and meanwhile, connecting arms and connecting supports are positioned through a hole so that the accuracy of hole positioning can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of seat frame welding, and in particular relates to a welding jig for a six-point seat cushion frame. 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 stay wire located on the front side of the frame tube, the seat side stay wire located on the left side of the frame tube, the connecting arms located at both ends of the rear side of the frame tube, the rear Seat horizontal tube and snake spring and snake spring hook frame for fixing the two ends of the snake spring, seat front horizontal steel wire and seat rear horizontal steel wire located on the right in the middle of the frame tube, connecting bracket set on the inner circumference of the front side of the frame tube, among which All kinds of steel wires are prone to deformation and difficult to position and weld. At the...

[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 stay wire located on the front side of the frame tube, the seat side stay wire located on the left side of the frame tube, the connecting arms located at both ends of the rear side of the frame tube, the rear Seat horizontal tube and snake spring and snake spring hook frame for fixing the two ends of the snake spring, seat front horizontal steel wire and seat rear horizontal steel wire located on the right in the middle of the frame tube, connecting bracket set on the inner circumference of the front side of the frame tube, among which All kinds of steel wires are prone to deformation and difficult to position and weld. At the same time, it is necessary to ensure the accurate positioning of the connecting arm and the frame pipe, ensure the accurate positioning of the connecting hole on the connecting arm, and ensure the quality of later assembly. Therefore, the welding difficulty of the entire structure is greatly increased. Therefore, In order to solve this problem, a welding fixture that can accurately position the frame tube and various parts and ensure the accuracy of their connection is needed
