Technical Field

[0001] This invention relates to a welding apparatus, and more particularly to a welding apparatus and method for automotive shock absorbers, belonging to the field of shock absorber welding technology. Background Technology

[0002] Automotive shock absorbers, also known as suspension dampers or shock absorbers, are an important component of the automotive suspension system. Their main function is to absorb and mitigate the impact and vibration caused by uneven road surfaces, thereby improving the vehicle's driving stability and ride comfort. Shock absorbers reduce the bouncing and swaying of the vehicle during driving by controlling the movement of the suspension system's springs. The connection points of shock absorbers need to be welded during the manufacturing process.

[0003] Existing automotive shock absorber welding equipment cannot easily align two metal tubes during actual use, which can easily lead to misalignment of the two metal tubes during welding, resulting in poor welding quality. Furthermore, during welding, workers need to manually rotate the metal tubes, which increases the workload for workers and makes them more susceptible to welding injuries from the laser welder. Summary of the Invention

[0014] A welding method for an automotive shock absorber welding device includes the following steps: Step 1: Place one of the metal tubes on the limiting seat and the other in the limiting cover, aligning the two metal tubes. Start the second motor to drive the rotating plate to rotate. When the first main extrusion ball contacts the first auxiliary extrusion ball, the rotating plate continues to rotate. The first auxiliary extrusion ball extrudes the first main extrusion ball, which shortens the second spring and drives the slide plate to slide on the slide bar. When the slide plate slides, it drives the moving plate to move. When the moving plate moves, it drives the positioning pin to move, causing the positioning pin to slide out of the rotating plate and the limiting plate. Step Two: At this point, the hydraulic telescopic rod starts, causing the moving plate to slide on the limit rod, which in turn moves the connecting plate and the support plate. When the support plate moves, it moves the laser welder closer to the connection point of the metal tube, and also moves the main gear to mesh with the auxiliary gear. The laser welder starts to weld the connection point of the metal tube. The first motor starts, causing the first rotating rod to rotate. When the first rotating rod rotates, it drives the main pulley to rotate. When the main pulley rotates, it drives the auxiliary pulley to rotate via the belt. When the auxiliary pulley rotates, it drives the second rotating rod to rotate. When the second rotating rod rotates, it drives the main gear to rotate. When the main gear rotates, it drives the auxiliary gear to rotate. When the auxiliary gear rotates, it drives the third rotating rod to rotate. When the third rotating rod rotates, it drives the limit seat to rotate, which in turn drives the two metal tubes to rotate, cooperating with the laser welder to perform welding at multiple points. Step 3: After welding is completed, the second motor starts and drives the rotating plate to rotate, which in turn drives the first main extrusion ball to move away from the first auxiliary extrusion ball. At this time, the second spring returns to its original position, driving the positioning column to move and insert into the limiting plate and the rotating plate to limit the limiting seat. When the second auxiliary extrusion ball contacts the second main extrusion ball, the rotating plate continues to rotate, and the second main extrusion ball extrudes the second auxiliary extrusion ball. At this time, the first spring shortens, the guide frame slides on the guide rod, and thus the limiting cover moves away from the metal tube. The workers then remove the metal tube after welding.

[0015] Beneficial technical effects of the present invention: 1. According to the automotive shock absorber welding device and welding method of the present invention, by setting a limiting seat and a limiting cover, it is easy to align the limiting seat and the limiting cover. When the second motor is started, it can drive the rotating plate to rotate. When the second auxiliary extrusion ball contacts the second main extrusion ball, the rotating plate continues to rotate. The second main extrusion ball can extrude the second auxiliary extrusion ball. At this time, the first spring is shortened, and the guide frame slides on the guide rod, thereby allowing the limiting cover to move away from the metal tube. This makes it easier for workers to remove the metal tube after welding, and the material removal is more convenient.

[0016] 2. By setting the main gear and auxiliary gear to cooperate, the second motor can drive the rotating plate to rotate. When the first main extrusion ball contacts the first auxiliary extrusion ball, the rotating plate continues to rotate. The first auxiliary extrusion ball can squeeze the first main extrusion ball. At this time, the second spring is shortened, which can drive the slide plate to slide on the slide rod. When the slide plate slides, it can drive the moving plate to move. When the moving plate moves, it can drive the positioning pin to move, sliding the positioning pin out of the rotating plate and the limiting plate. At this time, the hydraulic telescopic rod is activated, which can drive the moving plate to slide on the limiting rod, which can then drive the connecting plate and the support plate to move. When the support plate moves, it can drive the laser welder to move closer to the connection of the metal tube, and drive the main gear to move and cooperate with the auxiliary gear. The machine uses a gear meshing connection. When the laser welder is activated, it welds the joints of the metal pipes. The first motor starts, which drives the first rotating rod to rotate. The rotation of the first rotating rod drives the main pulley to rotate. The rotation of the main pulley drives the auxiliary pulley to rotate via a belt. The rotation of the auxiliary pulley drives the second rotating rod to rotate. The rotation of the second rotating rod drives the main gear to rotate. The rotation of the main gear drives the auxiliary gear to rotate. The rotation of the auxiliary gear drives the third rotating rod to rotate. The rotation of the third rotating rod drives the limit seat to rotate, which in turn drives the two metal pipes to rotate. This allows for multiple welding operations with the laser welder, eliminating the need for manual rotation of the metal pipes by the operator. This makes welding more convenient and safer.

Step 3: After welding is completed, the second motor 43 starts and drives the rotating plate 44 to rotate, which in turn drives the first main extrusion ball 6 to move away from the first auxiliary extrusion ball 67. At this time, the second spring 66 resets and drives the positioning column 61 to move and insert into the limiting plate 81 and the rotating plate 44 to limit the limiting seat 8. When the second auxiliary extrusion ball 71 contacts the second main extrusion ball 7, the rotating plate 44 continues to rotate, and the second main extrusion ball 7 squeezes the second auxiliary extrusion ball 71. At this time, the first spring 54 shortens, the guide frame 51 slides on the guide rod 53, and thus the limiting cover 5 moves away from the metal tube.

At this time, the hydraulic telescopic rod 2 starts, driving the moving plate 23 to slide on the limiting rod 12, which in turn drives the connecting plate 25 and the support plate 27 to move. When the support plate 27 moves, it drives the laser welder 28 to move closer to the connection point of the metal pipe.The main gear 37 moves and meshes with the auxiliary gear 82. The laser welder 28 then starts welding the joints of the metal tubes. The first motor 3 starts, driving the first rotating rod 34 to rotate. The rotation of the first rotating rod 34 drives the main pulley 33 to rotate, which in turn drives the auxiliary pulley 36 via the belt 35. The rotation of the auxiliary pulley 36 drives the second rotating rod 38 to rotate, which in turn drives the main gear 37 to rotate. The rotation of the main gear 37 drives the auxiliary gear 82 to rotate, which in turn drives the third rotating rod 83 to rotate. The rotation of the third rotating rod 83 drives the limit seat 8 to rotate, thereby rotating both metal tubes. This allows for multiple welding operations with the laser welder 28, eliminating the need for manual rotation of the metal tubes, making welding more convenient and safer.
