Auxiliary automobile frame welding tool

Abstract

The invention discloses an auxiliary automobile frame welding tool which comprises a bottom board (1), a plurality of sets of edge-pressing mechanisms on the top of the bottom board, and a plurality of supporting pieces (6). The multiple sets of edge-pressing mechanisms are scattered around the supporting pieces (6). Each edge-pressing mechanism comprises a driving unit (2), a driving rod (3) and a pressing rod (4) which are arranged on the top of the bottom board, wherein one end of the driving rod (3) is connected with the driving unit (2), the other end of the driving rod (3) is hinged to the pressing rod (4), and the driving rod (3) and the pressing rod (4) are fixed through a fixing piece. When an auxiliary automobile frame (15) is arranged on the tops of the supporting pieces (6), the driving units (2) can drive the driving rods (3) to move so that the lower front portion of each driving rod (3) can abut against the edge of the top of the auxiliary automobile frame (15) in a pressing mode. The auxiliary automobile frame welding tool can fix the auxiliary automobile frame stably and conveniently.

Description

technical field [0001] The invention relates to a tool, in particular to a welding tool for an auxiliary frame. Background technique [0002] The subframe can be regarded as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a bracket that supports the front and rear axles and suspensions, so that the axles and suspensions are connected to the "positive frame" through it, which is customarily called "sub-frame". The function of the sub-frame is to block vibration and noise and reduce its direct entry into the compartment, so it mostly appears on luxury cars and off-road vehicles, and some cars are also equipped with a sub-frame for the engine. In the traditional load-bearing body without subframe, the suspension is directly connected with the steel plate of the body. Therefore, the suspension rocker mechanism of the front and rear axles is all parts, not an assembly. After the subframe ...

AI Technical Summary

Problems solved by technology

[0003] At present, the sub-frame needs to be welded during the production process. During the welding process, a fixing device needs to be used to fix the frame. During the whole process, the sub-frame must be absolutely stable, otherwise it will affect the welding quality of the sub-frame. Once there is a problem with the welding of the subframe, it will cause the subframe to be easily damaged during use

The existing fixing device either fixes the subframe through a fixed groove or clamps it through simple clamping parts; the former is inconvenient to operate, especially for subframes of different sizes, while the latter The clamping force of the frame is not enough, and the sub-frame is prone to shake during the welding process
