Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of brackets, in particular to a tooling for installing a vehicle frame cross beam. Background Art

[0002] When the vehicle frame cross beam tube is welded together with the longitudinal beam, it needs to pass through the left and right longitudinal beam mounting holes. Since the edge of the hole needs to be welded to the cross beam tube, the fit tolerance between the cross beam tube and the longitudinal beam mounting hole is small, and it is not easy for the cross beam tube to pass through the longitudinal beam mounting hole. The traditional process plan is to manually insert the cross beam tube into one side of the longitudinal beam, and then into the other side of the longitudinal beam. Before the cross beam tube is inserted into the longitudinal beam, neither the left and right longitudinal beams nor the cross beam tube can be installed in the tooling for positioning and clamping. The weight and volume of the parts are large, and manual assembly is time-consuming and laborious. Moreover, since the assembly is not carried out under the condition of tooling positioning and clamping, it is difficult to assemble due to the misalignment of the left and right longitudinal beams, and the direction is not easy to control.
