Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a welding fixture for an automotive front door outer window sill assembly. Background Technology

[0002] With the continuous improvement of automobile manufacturing capabilities, people are not only pursuing high-performance and economical vehicles, but also paying more attention to passenger comfort. Therefore, the structure of automobile body components must not only possess functional characteristics but also conform to human-centered design. The automobile body structure should include the body shell, front panel components, doors, windows, exterior and interior trim, body accessories, seats, and ventilation, heating, cooling, and air conditioning systems. In trucks and special-purpose vehicles, this also includes the cargo box and other equipment. Welding fixtures for automobile components are crucial for ensuring welding quality and production efficiency. The welding fixtures are installed on the workbench, ensuring that the fixture's fixing points are secure and reliable. Precise positioning of key parts between the automobile components and the fixtures ensures that the positions of each part meet welding requirements.

[0003] The existing welding fixtures for the front door exterior window sill assembly still have certain deficiencies in terms of the structural strength of the front door exterior window sill assembly. The welding fixture equipment mainly places the workpiece to be welded in a specific position of the fixture, and ensures the accurate position of the workpiece in space by using locating pins, locating blocks or other locating elements. Various clamping mechanisms, such as bolts and nuts of manual fixtures, cylinders of pneumatic fixtures, and hydraulic cylinders of hydraulic fixtures, apply sufficient clamping force to the workpiece, so that the workpiece moves or deforms during the welding process.
