Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of frame assembly clamps, in particular to a universal frame assembly clamp. BACKGROUND

[0002] With the rapid development of the automobile industry, the frame, as the main load-bearing structure of the vehicle, is mainly composed of longitudinal beams, cross beams and connecting components. Among them, the longitudinal beam is the key component that bears the main load of the vehicle, and the cross beam is used to provide lateral support and overall rigidity. The quality and assembly precision of the frame directly affect the safety, stability and comfort of the vehicle. In order to ensure the high-precision assembly of the frame, various clamps are usually used on the production line to assist the fixation, positioning and assembly of the frame.

[0003] The frame assembly clamps widely used in the market at present are generally composed of a fixed base, a positioning module and a clamping mechanism, and their main function is to fix the components of the frame in position during welding or assembly. Common clamps are usually customized to adapt to the geometric structure of a specific frame. For example, some clamps use special positioning pins and customized clamp plates to ensure the precise position of the frame components, and then use hydraulic or pneumatic systems to achieve clamping function.

[0004] Although these clamps can meet the positioning and assembly requirements of the frame in a single production line, when the vehicle model is changed or the frame design is adjusted, new clamps often need to be re-customized, and the development cycle of new clamps is often long, which not only increases production costs, but also reduces production efficiency.
