Description

Technical Field

[0001] This utility model relates to the field of welding-related equipment technology, and in particular to a positioning and clamping system for welding base components. Background Technology

[0002] The base assembly typically employs a process where connectors (used to connect other components) are welded onto a base component. Currently, this welding process is widely achieved using laser welding technology. During welding, the base component and connectors need to be positioned separately, and a clamping device is used to reliably hold the connectors to ensure welding quality. However, existing clamping devices mostly adopt an integrated structure, achieving full clamping of the connectors only through the overall up-and-down movement. This structure has the following prominent problems in practical applications: First, due to machining errors between the base component and the connectors, the integrated clamping device is prone to insufficient clamping force in some welding areas, leading to welding defects such as incomplete welds and false welds; second, if the clamping force is too high, it can easily cause workpiece deformation or even surface damage. In addition, such clamping devices are usually difficult to adjust and have poor adaptability, making it difficult to flexibly adapt to connectors of different sizes or welding positions, resulting in the device being unable to effectively avoid the welding area, thus adversely affecting welding quality and production efficiency. Utility Model Content

[0003] The main purpose of this utility model is to solve the problems in the background technology and provide a positioning and clamping system for welding base components. Through a modular design with adjustable height and adaptive clamping, it can ensure that the welding area is fully clamped while effectively avoiding problems such as uneven force, difficulty in adjustment and welding interference caused by rigid clamping in traditional integrated clamping devices.
