Description

A frame assembly tool

technical field

The utility model relates to the field of automobiles, in particular to a vehicle frame assembly tool.

Background technique

The frame is the matrix for the assembly of components of various subsystems in the vehicle carrying platform, and its quality is directly related to the usability and safety of the vehicle.

As shown in Figure 1, it is a schematic structural diagram of a vehicle frame, which consists of a left longitudinal beam, a right longitudinal beam, a swing arm through the shaft tube, a lower thrust rod seat, a cab bracket, a beam, a steering support, a sealing plate, and a bracket And other structures assembled and welded. At present, in the welding process of this type of vehicle frame, it is first necessary to carry out tailor welding of the left longitudinal beam and the right longitudinal beam. Both ends of the beam are suspended beam structures, which makes positioning more difficult. Existing manufacturers usually use rigid positioning welding tooling on large welding platforms, that is, spot welding the support rods on the left and right longitudinal beams and the two sides. Spot welding reinforcement plate, although the design of this kind of tooling can also play a certain role in positioning and anti-deformation, but because the support rod and reinforcement plate are directly spot-welded with the left longitudinal beam, right longitudinal beam and platform, it is difficult for the left longitudinal beam , The right longitudinal beam was damaged to a certain extent, which buried a certain safety hazard for future use, and at the same time caused certain damage to the large welding platform; and when assembling other components in the future, it is necessary to remove the tooling and readjust it , which not only increases the workload, but also produces a certain deviation in the assembly accuracy due to the secondary positioning and clamping; in addition, due to the long length and large size of the left and right longitudinal beams after tailor welding, they cannot be machined without corresponding tooling , which directly leads to the inability to guarantee the size of important parts, and the subsequent assembly cannot be carried out smoothly. If additional design and manufacture of tooling is required, the cost will be relatively high. Therefore, it is urgent to solve.
