Description

Technical Field

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

[0002] The frame is the main skeleton of the truck, which is composed of long beams, cross beams, side beams, angle steel and other components. Its main function is to support the entire weight of the truck and transfer the load to the tires and axles. The choice of frame material should be determined according to the purpose and load of the truck. Commonly used materials include steel pipes, aluminum alloys and carbon fiber.

[0003] At present, in order to ensure the accuracy of the welding position of the dump truck suspension seat, auxiliary positioning is required through the installation of tooling to ensure the position of the suspension seat on the frame.

In order to ensure the installation height of the suspension seat, the adjusting bolt needs to be turned until the height reaches a suitable level, and finally the suspension seat is positioned and assembled on the installation tool. Although the overall structure is simple, in actual operation, the disassembly and assembly of the upper and lower brackets and the adjustment of the height all take a long time, affecting the connection efficiency between the suspension seat and the frame. Among them, the height adjustment is a manual operation, which has a large human influence and is difficult to ensure the adjustment accuracy. Therefore, a tool for frame installation is proposed.
