Description

Technical Field

[0001] This invention relates to the field of laser welding technology for automotive parts, and in particular to an auxiliary device for laser welding of automotive parts and its usage method. Background Technology

[0002] In the automotive parts manufacturing industry, the automotive clutch is a key component, and its processing quality directly affects the overall performance and operational reliability of a vehicle. Among these processes, the welding of the clutch body and its cover is a crucial step in clutch production, and the quality of this welding directly determines key indicators such as the clutch's structural strength and service life.

[0003] Traditional welding processes for automotive clutch bodies and covers have significant shortcomings in several key aspects.

[0004] Current technology primarily relies on manual operation. Operators must manually move the automotive clutch body and cover to the welding station and adjust their positions to ensure accurate alignment. This process is not only labor-intensive, but also inherently limited by manual operation. Furthermore, the assembly and positioning are also done manually, requiring operators to precisely place the cover in the designated position on the clutch body and perform initial fixation. It is difficult to guarantee consistent positioning accuracy with each loading. Especially during prolonged continuous operation, operator fatigue can easily lead to deviations in the loading position, thus affecting the subsequent welding quality.

[0005] Furthermore, many companies still rely on manual welding in the welding process. Manual welding not only demands extremely high skill levels from operators, requiring extensive professional training to master the techniques, but the welding quality also largely depends on the operator's experience and condition. Welding skill levels vary among different operators, and even the same operator may produce fluctuating quality at different times, making it difficult to maintain consistent welding quality.

[0022] The combined positioning mechanism includes a first horizontal bar 12, with a rotating column 13 fixedly connected to the upper end of the first horizontal bar 12. The upper end of the rotating column 13 penetrates the inner top wall of the mounting frame 6 and extends into the interior of the mounting groove 7. The rotating column 13 is rotatably connected to the mounting frame 6. A second electric telescopic rod 19 is installed at the upper end of the first horizontal bar 12.

A connecting sleeve 21 is slidably sleeved at the lower end of the connecting rod 22. A tension spring 23 is provided inside the connecting sleeve 21. The two ends of the tension spring 23 are fixedly connected to the connecting rod 22 and the connecting sleeve 21, respectively. A magnetic chuck 20 is fixed at the lower end of the connecting sleeve 21. Two limiting rods 18 are fixed at the upper end of the magnetic chuck 20.

Multiple contact strips 40 that cooperate with the contact switch 41 are fixed on the side wall of the connecting column 42. The multiple contact strips 40 are evenly spaced along the circumference of the connecting column 42.

[0025] The rotation of the rotating sleeve 28 can drive the laser welding gun 35 to rotate circumferentially. When the rotating sleeve 28 rotates, when the contact switch 41 contacts the contact bar 40, the third electric telescopic rod 37 can be activated to extend, driving the laser welding gun 35 to descend and contact the gap between the cover 39 and the car clutch body 38. At the same time, the laser welding gun 35 can be activated to complete the welding of the gap.

[0026] A second crossbar 32 is fixedly connected to the outer wall of the rotating sleeve 28. A second guide sleeve 36 is fixed to the lower end of the second crossbar 32. A third electric telescopic rod 37 is fixedly installed on the inner wall of the second guide sleeve 36. A first guide sleeve 33 is slidably sleeved at the lower end of the second guide sleeve 36. The telescopic end of the third electric telescopic rod 37 is fixedly connected to the first guide sleeve 33. A vertical rod 34 is fixed to the lower end of the first guide sleeve 33.

[0027] A guide rod 25 is fixed to the upper end of the pressure block 27. A compression switch 26 that cooperates with the guide rod 25 is embedded inside the mounting bracket 6. The compression switch 26 is electrically connected to the first electric telescopic rod 16. The guide rod 25 is thicker at the top and thinner at the bottom. When the guide rod 25 compresses the compression switch 26, it can activate the extension of the first electric telescopic rod 16. When the guide rod 25 and the compression switch 26 are not compressing, the first electric telescopic rod 16 retracts.

[0028] The rotating structure includes a motor 31 mounted on the upper end of the pressure block 27. The output shaft of the motor 31 is fixedly connected to a third gear 30. A second gear 29 is fixedly sleeved on the side wall of the rotating sleeve 28. The second gear 29 meshes with the third gear 30.

[0029] The working principle of the laser welding auxiliary device for automotive parts processing is as follows: The first scissor lifter 4 and the second scissor lifter 5 lift the cover 39 and the automotive clutch body 38 respectively, and load the cover 39 into the inner side of the first loading groove 8 and the automotive clutch body 38 into the inner side of the second loading groove 10. The cover 39 is positioned by the first guide bar 9 and the automotive clutch body 38 is positioned by the second guide bar 11.

[0030] Then, the second electric telescopic rod 19 is activated to extend, and the magnetic chuck 20 is driven to descend through the connecting sleeve 21 and connecting rod 22. The magnetic chuck 20 is used to pick up the cover 39. Then, the second electric telescopic rod 19 is activated to retract, which drives the cover 39 to move upward.

[0031] Then, the hydraulic cylinder 24 is extended, which drives the pressure block 27 to move down through the connecting column 42. When the pressure block 27 moves down, it can drive the guide rod 25 to move down. The guide rod 25 can trigger the squeeze switch 26. The squeeze switch 26 can then extend the first electric telescopic rod 16, which can move the rack 15. Since the rack 15 meshes with the first gear 14, it can drive the rotating column 13 to rotate. The rotating column 13 can drive the first crossbar 12 to rotate 180 degrees, which can move the suction cover 39 to the top of the car clutch body 38.

[0032] As the hydraulic cylinder 24 continues to extend, it can drive the pressure block 27 to press down on the pressure rod 17. Through the limit rod 18, it can drive the magnetic chuck 20 to move down. At this time, the tension spring 23 is stretched, which can press the cover 39 down onto the upper end of the car clutch body 38.

[0033] Then, the motor 31 is started, driving the third gear 30 to rotate. Since the third gear 30 meshes with the second gear 29, it can drive the rotating sleeve 28 to rotate. The rotation of the rotating sleeve 28 can drive the laser welding gun 35 to rotate circumferentially. When the rotating sleeve 28 rotates, when the contact switch 41 contacts the contact bar 40, it can activate the extension of the third electric telescopic rod 37, driving the laser welding gun 35 to descend and contact the gap between the cover 39 and the car clutch body 38. At the same time, it can activate the laser welding gun 35 to complete the welding of the gap.

[0034] A method for using a laser welding auxiliary device for processing automotive parts, the method comprising the following steps: S1, the cover 39 and the car clutch body 38 are lifted and loaded by the first scissor lifter 4 and the second scissor lifter 5 respectively; S2, activate the combined positioning mechanism to lift and absorb the cap 39; S3, start the welding mechanism, which can simultaneously drive the swing mechanism. The swing mechanism drives the combined positioning mechanism to swing, and moves the sucked-up cover 39 to above the car clutch body 38. S4, and then as the welding mechanism continues to operate, the cover 39 can be pressed down onto the upper end of the car clutch body 38 to achieve the combined positioning of the cover 39 and the car clutch body 38. Then, the cover 39 and the car clutch body 38 are welded together by the welding mechanism. S5, finally start the welding mechanism to reset, and at the same time the swing mechanism and the combined positioning mechanism reset. Then, remove the welded cover 39 and the car clutch body 38.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
