[0001] The invention relates to the technical field of welding fixtures, in particular to a laser welding fixture for a metal control arm of an automobile. Background Art

[0002] With the continuous development of the automobile industry, consumers have put forward higher requirements for automobile safety, comfort and handling. As one of the key components of the automobile suspension system, the performance and quality of the automobile metal control arm directly affect the driving quality and safety performance of the automobile. When welding automobile metal control arms, traditional welding processes gradually expose some problems that are difficult to meet the high standards of modern automobile manufacturing, which has prompted the application and development of laser welding technology and its matching special fixtures.

[0003] Patent No. CN213798160U relates to a laser welding fixture, which includes a base and a clamping plate arranged relatively to each other, and the clamping plate can move relative to the base to clamp or release the parts to be welded. A glass plate is installed in the welding work area of ​​the clamping plate. The laser welding fixture provided by the present application can not only allow the laser to penetrate the glass plate to weld the parts to be welded by arranging the glass plate on the clamping plate, but also load the welding part through the glass plate to ensure the pressure required for welding the welding part in a molten state. The device effectively combines the bonding surfaces of the parts to be welded, thereby ensuring the bonding force of the welding part and improving the welding effect. However, the device is prone to misalignment of the welded parts due to improper placement of the welded parts by the staff during use, thereby affecting the welding and causing welding errors.

When the control arm welding starts, the parts to be welded are placed in the processing area, and the parts to be welded can be clamped to facilitate the welding of the welding parts. In the process of clamping, the buffering of the buffer spring is used to reduce the impact force on the welded parts to avoid damage to the welded parts. At the same time, the welding machine parts can be centered and calibrated to ensure that the position of the welded parts is accurate during welding, so that the robotic arm can perform welding operations more smoothly and make the weld formation more beautiful and uniform.

At the same time, the welding machine parts can be calibrated to ensure the accurate position of the welded parts during welding, so that the robotic arm can perform welding operations more smoothly and the weld formation is more beautiful and uniform.

[0009] 2. The laser welding fixture for the automobile metal control arm can automatically close during the clamping process of welding through the coordinated operation of the fixed plate three, the rotating rod, the protective plate, the connecting rod two, the push plate one, the auxiliary plate, and the mechanical arm to avoid sparks generated during welding from splashing randomly and causing injuries to workers.
