Description

Technical Field

[0001] The utility model belongs to the technical field of welding jigs, and more specifically, it particularly relates to a low-cost quick-change structure for fixture sub-assembly. Background Technique

[0002] When producing a new vehicle model, the left and right front longitudinal beams need to be welded at the front of the body-in-white. The hole position tolerance and the open dimension between the longitudinal beams are key control dimensions and require a dedicated fixture sub-assembly to ensure. In order to manufacture the fixture sub-assembly at low cost, the sub-assembly is cut and welded from the surplus materials of 5mm high-strength steel plates, and then the quick change of the longitudinal beam is ensured through a pin structure.

[0003] According to CN202121511494.1, the utility model discloses a general quick die-changing tooling for the group welding fixture of the side wall components of a rail vehicle, belonging to the technical field of the welding of the side wall components of a rail vehicle. The utility model includes a support body for carrying the group welding tooling with the side wall components assembled. The support body is configured with connecting plates connected to the positioner at both ends, and a bearing area adapted to the length direction and width direction of the group welding tooling is formed on the upper surface of the support body; at least two quick-release structures are oppositely arranged at the edge positions of the bearing area for detachably connecting with the group welding tooling; wherein, the bearing area is an open structure corresponding to the length direction or width direction of the group welding tooling. On the premise of ensuring that the original functions such as the fastening and reverse installation of the group welding tooling with the side wall components assembled remain unchanged, when the product is changed in type, the die-changing efficiency is high, the versatility is good, and the waiting time of the positioner and the waste of the number of positioners are reduced, the floor area occupied is saved, the production efficiency is improved, and the production cost is saved.

Since the pins and the sub-assembly are in a separated state, the pins are easy to be lost when placed, and the staff needs to find the pins for use, which affects the staff's use of the fixture sub-assembly to fix the longitudinal beam.
