Description

Technical Field

[0002] The bumper is one of the components of the car. The bumper is installed at the front and rear ends of the car. It not only has a decorative function, but more importantly, it is a safety device that absorbs and mitigates external impact, protects the car body and protects the safety of the occupants. The bumper has the functions of safety protection, vehicle decoration, and improving the aerodynamic characteristics of the vehicle. From the perspective of safety, it can play a buffering role in the event of a low-speed collision accident, protecting the front and rear bodies of the car; it can play a certain role in protecting pedestrians in the event of an accident with pedestrians. From the appearance point of view, it is decorative and has become an important component for decorating the appearance of the car; at the same time, the car bumper also has a certain aerodynamic effect. At the same time, in order to reduce the damage to the occupants in the event of a side collision accident, the car is usually equipped with a door bumper to enhance the anti-collision impact of the door.

[0003] Since the bumper is not an integrally formed structure, welding equipment is required for welding operations during the production and processing of the bumper, and a clamp is required to fix the bumper during welding. In the authorized Chinese utility model patent "Announcement No.: CN219325537U, Name: Bumper Welding Tooling", when the moving screw rotates forward, the two moving parts will move in relative directions, thereby driving the two abutting parts to move relative to each other until the bumper is clamped, and when the moving screw is reversed, the two moving parts will move in opposite directions, so that the two abutting parts move away from the bumper, thereby loosening the bumper.

[0004] In the above application, a screw is used to drive the abutment part to move, so as to achieve clamping and releasing of the car bumper. However, the screw provides the main clamping force. After long-term use, the threads on the screw are greatly worn, which can easily cause thread slippage, resulting in unstable clamping of the car bumper or even falling. At the same time, the workbench and installation position in the above application will block the left, right and bottom sides of the car bumper, affecting the welding of the car bumper.
