Description

Technical Field

[0001] The invention relates to the technical field of component welding, and in particular to a universal welding device used for processing automobile components. Background Art

[0002] As the foundation of the automotive industry, auto parts need to be produced in large quantities, and the parts need to be welded during the production process.

[0003] The Chinese patent with publication number CN118875561B discloses a universal welding equipment for automobile parts processing. In the operation of clamping and loosening the parts by driving the clamping assembly through the connecting seat, the top plate can drive the rubber column to hit the guide plate to avoid the guide plate from sticking welding slag, making the welding slag cleaning more thorough, realizing the linkage between the clamping assembly clamping or loosening the parts and the top plate driving the rubber column to hit the guide plate, simplifying the operation and improving the overall work efficiency. Secondly, the clamping seat can be quickly disassembled by pushing the push block, and the pull block is pulled upward and then rotated to change the clamping direction of the clamping assembly. The operation is simple and intuitive.

[0004] However, the above invention has the following shortcomings: during the welding base process of the existing cylindrical parts, the welding slag splashed during welding will adhere to the welding head, so the welding head needs to be cleaned. Most welding heads are only cleaned once after completing the welding of multiple parts, and the cleaning frequency is relatively small. As the number of welding times increases, the welding head that is not cleaned in time will adhere to a large amount of welding slag, thereby affecting the welding quality of the welding head.

[0018] First, the present invention provides a cleaning unit. After welding is completed, the electric telescopic rod drives the welding head to reset. When the sliding rod contacts the mounting block, the sliding rod and the first rack stop moving, and the movable frame is continuously retracted into the fixed frame, so that the first gear moves and rotates on the first rack. The rotation of the first gear drives the rotating shaft, the L-shaped rod and the two cleaning brushes to rotate in the direction of the welding head. When the electric telescopic rod drives the welding head to weld the parts, when the sliding rod is away from the mounting block, the tension spring drives the first rack to move in the direction of the bracket.

[0019] Secondly, during welding, the rotating shaft of the present invention drives the extrusion block to rotate, and the extrusion block rotates to extrude the fixed bar to drive the connecting rod and the baffle to move toward the welding head, so that the baffle moves to the welding end of the welding head, so that the welding slag in the welding process will not splash onto the welding head behind the baffle, thereby being able to block the splashing welding slag.

[0020] Thirdly, the present invention sets a blowing unit. After welding is completed, the connecting spring drives the baffle to reset. The baffle squeezes the L-shaped block to drive the sliding piston rod to move, so that the sliding piston rod moves into the fixed sleeve, so that the gas in the fixed sleeve is ejected from the nozzle through the one-way air outlet pipe, the fixed pipe and the arc pipe, thereby cooling the weld by blowing.

[0021] Fourthly, through the setting of the rotating unit, the present invention causes the sliding seat to stop moving when the welding head moves to the welding position of the part, while the electric telescopic rod drives the fixed rod to continue to move. The movement of the fixed rod drives the reset spring to stretch and elastically deform. The movement of the fixed rod causes the extrusion protrusion to drive the movable rod and the second rack to move. The movement of the movable rod drives the installation spring to stretch and elastically deform. The movement of the second rack drives the second gear, the rotating column and the placement plate to rotate. The rotation of the placement plate drives the part and the pressure plate to rotate, so that the welding head performs circular welding on the part. BRIEF DESCRIPTION OF THE DRAWINGS
