Description
Technical Field
[0001] This utility model relates to the field of welding fixtures, specifically a fixture for easy lifting and adjustment for vehicle frame welding. Background Technology
[0002] A positioning support fixture for vehicle frame welding is a tool used to maintain the correct position and posture of the vehicle frame. Designed for use during the welding process to ensure accurate alignment and consistency of the weld joints, the fixture is typically made of metal with a specific shape and holes to fit the vehicle frame design. Existing vehicle frame welding fixtures rely on clamping plates on both sides to fix the frame. However, the shape of the vehicle frame is irregular, leading to unstable clamping and affecting the welding effect. One application, CN202420369652.1, describes a positioning support fixture for vehicle frame welding. This invention uses a support plate, a fixed base, and clamping plates to achieve multi-faceted clamping and fixing of the vehicle frame, improving the welding effect and achieving stable frame fixation. However, this fixture still has some shortcomings in its use: the base has a fixed height, making it impossible to adjust the height of the fixture by adjusting the base, which prevents welders from adjusting it according to the different weld points on different vehicle frames, thus affecting welding efficiency.
