[0002] As an indispensable core component in the vehicle suspension system, the core function of a shock absorber is to effectively relieve the oscillation generated by the rebound of the shock-absorbing spring after absorbing vibrations and resist strong impacts from complex road surfaces, thereby ensuring the smoothness and comfort of driving. In the precise manufacturing process of shock absorbers, the precise welding process on the outside of the oil storage cylinder is particularly important, especially the stable connection between the bracket and the spring plate, which directly relates to the overall performance and service life of the shock absorber.

[0003] However, the current commonly used welding method for the shock absorber housing and the support is that workers need to manually align and fit the shock absorber housing and the support precisely first, and then while maintaining this precise position, rotate or adjust their relative positions so that the welding gun can precisely touch and weld the connection between the two. This highly manual operation method not only has a high labor intensity, but also is extremely likely to lead to low welding efficiency due to human factors, and it is more difficult to ensure the stability and consistency of welding quality.

[0029] Embodiment 1

[0030] Please refer to Figures 1-5As shown in the figure, a positioning mechanism for welding an automobile shock absorber includes a bottom plate 1 and a cylinder 2. A curved limiting block 3 is fixedly connected to the upper side of the bottom plate 1. An outer shell 4 is arranged outside the curved limiting block 3. The cylinder 2 is used to drive the outer shell 4 to slide on the outer surface of the curved limiting block 3. A first fixing plate 5 is fixedly connected to one side of the bottom plate 1. A first driving module 6 is fixedly installed outside the first fixing plate 5. The output end of the first driving module 6 penetrates through the first fixing plate 5 and is fixedly connected to a rotating box 7. A clamping mechanism 8 is arranged inside the rotating box 7. A support 9 is arranged in the middle of the clamping mechanism 8. Moving mechanisms 10 are arranged on opposite sides of the bottom plate 1. The outer surfaces of the moving mechanisms 10 are both threadedly connected with movable frame bodies 11. A welding head 12 is arranged inside the movable frame bodies 11. A second fixing plate 13 is fixedly connected to the upper side of the bottom plate 1. The second fixing plate 13 is fixedly connected to the base of the cylinder 2. The output end of the cylinder 2 is fixedly connected to a rotating member 14. The rotating member 14 is rotatably connected to the open end of the outer shell 4.

[0031] In this embodiment, first, the staff places the outer shell 4 outside the adapted curved limiting block 3, then places the support 9 at the middle of one side of the rotating box 7, and then clamps and fixes the support 9 through the clamping mechanism 8. Secondly, the cylinder 2 is started. The cylinder 2 pushes the outer shell 4 to move to one side until it tightly abuts against the support 9. Then, after moving the movable frame body 11 to the welding position through the two moving mechanisms 10 on both sides, the first driving module 6 is started. The first driving module 6 drives the outer shell 4 to rotate through the clamping mechanism 8 inside the movable frame body 11, thereby driving the support 9 that is tightly abutted to rotate synchronously. Then, the welding head 12 is started. The welding head 12 can perform comprehensive welding on the connection between the outer shell 4 and the support 9. When the welding of the connection between the welding head 12 and the outer shell 4 is completed, the movable frame body 11 is moved away again through the moving mechanism 10. Finally, after the clamping mechanism 8 is moved away from the support 9, the staff can take out the welded automobile shock absorber outer shell. This device not only improves the welding efficiency of the shock absorber outer shell, but also enhances its welding quality, further improving the practicability and applicability.

[0032] Embodiment 2

[0033] Please refer to Figure 4As shown, the clamping mechanism 8 includes a second driving module 801, which is installed outside the rotating box 7. The output end of the second driving module 801 extends into the rotating box 7 and is fixedly connected to a double-threaded screw 802. The double-threaded screw 802 is rotatably connected to the inner wall of the rotating box 7. Two fixed rods 803 are fixedly connected inside the rotating box 7, and the two fixed rods 803 are symmetrically distributed on both sides of the double-threaded screw 802. Sliding blocks 804 are threadedly connected to both opposite sides of the double-threaded screw 802. The sliding blocks 804 are slidably connected to the two fixed rods 803. Activity plates 805 are fixedly connected to the outer surfaces of the sliding blocks 804. The activity plates 805 extend outside the rotating box 7, and arc-shaped clamping plates 806 are also fixedly connected to the inner sides of the activity plates 805. A notch matching the activity plates 805 is formed on the outer surface of the rotating box 7.

[0034] In this embodiment, first, the second driving module 801 is turned on. The second driving module 801 drives the double-threaded screw 802 to rotate, thereby driving the sliding blocks 804 on both sides to approach each other, so that the arc-shaped clamping plates 806 on the inner sides of the activity plates 805 abut and clamp the arc-shaped ring of the support 9. Since the inner sides of the arc-shaped clamping plates 806 are closely attached to the outer sides of the support 9, when the base of the support 9 is under pressure, the support 9 is prevented from falling out of the arc-shaped clamping plates 806, thereby avoiding the problem of welding failure.

[0035] Embodiment 3

[0036] Please refer to Figure 3 As shown, the moving mechanism 10 includes a threaded rod 1001, the outer surface of the threaded rod 1001 is threadedly connected to the movable frame 11. Both ends of the threaded rod 1001 are rotatably connected to wing plates 1002, and the wing plates 1002 are fixedly connected to the bottom plate 1. A third driving module 1003 is fixedly installed outside one of the wing plates 1002. The output end of the third driving module 1003 extends into the inner side of the wing plate 1002 and is fixedly connected to the threaded rod 1001. Chute grooves 101 are formed on both opposite sides of the bottom plate 1. The movable frame 11 is slidably connected to the bottom plate 1 through the chute grooves 101.

[0037] In this embodiment, first, the third driving module 1003 is turned on. The third driving module 1003 drives the threaded rod 1001 to rotate, thereby driving the threadedly connected movable frame 11 to rotate. At the same time, since two moving mechanisms 10 are provided in this device and both threaded rods 1001 are threadedly connected to the movable frame 11, the movable frame 11 can move along the direction of the chute grooves 101, thereby driving the welding head 12 inside the movable frame 11 to approach the welding position for welding the housing 4 and the support 9 or move away from the welding position to pick up the shock absorber parts.

[0038] The working principle and use process of this device are as follows: first, the staff puts the shell 4 into the outside of the matching arc-shaped limit block 3, places the support 9 in the middle of one side of the rotating box 7, and then turns on the driving module 2 801. The driving module 2 801 drives the double-thread screw 802 to rotate, and then drives the sliding blocks 804 on both sides to approach each other, so that the arc-shaped clamping plate 806 on the inner side of the movable plate 805 contacts and clamps the arc-shaped ring of the support 9. Since the inner side of the arc-shaped clamping plate 806 is tightly fitted with the outer side of the support 9, the support 9 is prevented from falling out of the arc-shaped clamping plate 806 when the base of the support 9 is under pressure, thereby causing the problem of welding failure. Secondly, turn on the cylinder 2, and the cylinder 2 pushes the shell 4 to move to one side until it is tightly against the support 9. Then turn on the driving module 3 1003, drive The movable module three 1003 drives the threaded rod 1001 to rotate, which can then drive the threaded connected movable frame 11 to move to the welding position, and then turn on the driving module 6. The driving module 6 drives the outer shell 4 to rotate through the clamping mechanism 8 inside the movable frame 11, driving the tightly abutted support 9 to rotate synchronously, and then turn on the welding head 12. The welding head 12 can fully weld the connection between the outer shell 4 and the support 9. After the welding of the connection between the welding head 12 and the outer shell 4 is completed, the movable frame 11 is moved away again through the moving mechanism 10, and finally the clamping mechanism 8 is moved away from the support 9. The staff can then take out the welded automobile shock absorber housing. This equipment not only improves the welding efficiency of the shock absorber housing, but also enhances its welding quality, thereby further improving its practicality and applicability.
