[0027] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0028] Figure 1 The figure is a front view of the overall structure of a welding fixture for processing a rear seat back tube frame of an automobile according to one embodiment of the present disclosure.

[0029] like Figure 1-Figure 5 As shown, the welding fixture for processing the rear seat back tube frame of the automobile seat disclosed in the present invention may include: an operating table assembly 1, a rotating mechanism 2, a clamping mechanism 3 and other components.

[0030] like Figure 2As shown, in the present disclosure, the operating table assembly 1 includes an operating table body 11, a limiting slot 12 and a support rod 13, wherein the limiting slot 12 is opened on the surface of the operating table body 11, and the support rod 13 is fixedly connected to the bottom of the operating table body 11.

[0031] Therefore, the support rod 13 is used to support the rotating mechanism 2 and the clamping mechanism 3 to ensure the stability of the working state, and the limiting groove 12 is used to limit the rotating mechanism 2 to prevent rotation during welding to affect the welding effect.

[0032] like Figure 3 As shown, in a preferred embodiment, the rotating mechanism 2 includes a rotating column 21, a limiting magnetic disk 22, a rotating gear ring 23, a limiting gear ring 24, an adjusting gear ring 25, a rotating handle 26 and an anti-skid rubber sleeve 27, wherein the rotating column 21 is rotatably connected to the top of the operating table body 11 through a bearing and is located above the limiting slot 12, the limiting magnetic disk 22 is fixedly sleeved on the outside of the rotating column 21, the rotating gear ring 23 is fixedly sleeved on the outside of the rotating column 21 and is located below the limiting magnetic disk 22, the limiting gear ring 24 is fixedly sleeved on the outside of the bottom of the rotating column 21, the adjusting gear ring 25 is located inside the limiting slot 12 and is engaged with the limiting slot 12, the adjusting gear ring 25 is meshed with the rotating gear ring 23 and the limiting gear ring 24, the rotating handle 26 is fixedly connected above the adjusting gear ring 25, and the anti-skid rubber sleeve 27 is fixedly sleeved on the outside of the rotating handle 26.

[0033] Therefore, when it is necessary to weld the back of the pipe frame, the operator pulls the handle to pull the adjusting toothed ring 25 out of the limiting groove 12 and adsorbs the adjusting toothed ring 25 through the limiting magnetic disk 22. At this time, the adjusting toothed ring 25 is meshed with the rotating toothed ring 23. Then the operator rotates the rotating handle 26 to drive the adjusting toothed ring 25 to rotate. The rotation of the adjusting toothed ring 25 drives the rotating toothed ring 23 to rotate. The rotation of the rotating toothed ring 23 drives the rotating column 21 to rotate. The rotation of the rotating column 21 can drive the clamping mechanism 3 to rotate so that the back of the pipe frame rotates in front of the operator. After the adjustment is completed, the operator puts the adjusting toothed ring 25 into the limiting groove 12 again for limiting. At this time, the adjusting toothed ring 25 is meshed with the limiting toothed ring 24 to ensure the stability of the pipe frame.

[0034] like Figure 4-5As shown, in the present disclosure, the clamping mechanism 3 includes a rotating block 31, a first sliding groove 32, a motor 33, a bidirectional screw 34, a sliding rod 35, a second sliding groove 36, a clamping base 37, an adjusting screw 38 and a sliding clamping plate 39, wherein the rotating block 31 is fixedly connected to the top of the rotating column 21, the first sliding groove 32 is opened on the surface of the rotating block 31, the motor 33 is fixedly connected to the outside of the rotating block 31, and the output end of the motor 33 passes through the rotating block 31 and extends into the first sliding groove 32, and one end of the bidirectional screw 34 is connected to the motor 3 The output end is fixedly connected to the other end and is rotatably connected to the inner wall of the rotating block 31 through a bearing. The sliding rod 35 is threadedly sleeved on the outside of the bidirectional screw rod 34 and is located above the first sliding groove 32. The second sliding groove 36 is opened on the surface of the sliding rod 35. The clamping bottom plate 37 is fixedly connected to the outside of the sliding plate. The adjusting screw 38 is threadedly connected to the top of the sliding rod 35 and passes through the top of the sliding rod 35 into the second sliding groove 36. The sliding clamping plate 39 is rotatably connected to the bottom of the adjusting screw 38 through a bearing and is located below the adjusting screw 38.

[0035] Therefore, before welding, the operator turns on the motor 33 according to the size of the pipe frame. The rotation of the motor 33 drives the bidirectional screw 34 to rotate. The rotation of the bidirectional screw 34 drives the two sliding rods 35 to move toward each other until the distance between the two sliding rods 35 matches the size of the pipe frame. Then, the sliding clamping plate 39 is driven to slide in the second sliding groove 36 by rotating the adjusting screw 38 to cooperate with the clamping bottom plate 37 to clamp the pipe frame stably.
