[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The following describes in detail the specific implementation of the present invention with reference to specific embodiments. Embodiment

[0031] Refer to Figures 1 to 7 , a welding device for manufacturing sports equipment, including a bottom plate 1, on which a placement table 2 for guiding the discharging of climbing pipe fittings 4 and a welding robot 5 for welding are provided. On one side of the placement table 2, a positioning table 6 for positioning the welding of climbing pipe fittings 4 one by one is provided. On the positioning table 6, a number of equally spaced positioning blocks 7 are provided. It further includes: A welding transfer and positioning mechanism, which is installed on the positioning table 6 and is used for positioning the climbing pipe fittings 4 one by one at equal intervals for welding treatment. The welding transfer and positioning mechanism includes a transfer plate 8 for transferring and positioning the connection of the climbing pipe fittings 4, a first support block 9 and a second support block 10. The first support block 9 is fixedly connected to both ends of the transfer plate 8, and the second support block 10 is movably installed on the transfer plate 8.

[0032] Furthermore, the welding transfer and positioning mechanism further includes a rotating link 15 and a fixing plate 17 for pulling the first support block 9 and the second support block 10 for transfer connection. One end of the rotating link 15 is rotatably connected to the transfer plate 8 through a first connecting shaft 16, and the other end of the rotating link 15 is rotatably connected to the fixing plate 17 through a second connecting shaft 18. The fixing plate 17 is fixedly installed on the positioning table 6.

[0033] Furthermore, the welding transfer and positioning mechanism further includes an eccentric wheel 19, a collar 20 and a docking rod 21 for eccentric synchronous control connection. The eccentric wheel 19 is eccentrically fixedly connected to the second connecting shaft 18. A collar 20 is sleeved and rotatably connected on the eccentric wheel 19, and the two collars 20 are connected and fixed through a docking rod 21. The second connecting shaft 18 is rotatably connected to the output shaft of a second motor 23 through a synchronous belt 22. The second motor 23 is fixedly installed inside the positioning table 6.

[0034] Furthermore, the welding and material transfer positioning mechanism further includes a first bidirectional lead screw 11 and a first motor 14 for adjusting and controlling the linear movement of the second support block 10. The second support block 10 is slidably connected to the transfer plate 8 in a limited manner, the second support block 10 is threadedly connected to the first bidirectional lead screw 11, the first bidirectional lead screw 11 is rotatably connected to the transfer plate 8, a worm gear 12 is fixedly connected to the first bidirectional lead screw 11, a worm 13 is meshed with the worm gear 12, the worm 13 is rotatably connected to the transfer plate 8, the worm 13 is fixedly connected to the output shaft of the first motor 14, and the first motor 14 is fixedly installed on the transfer plate 8.

[0035] Furthermore, an inclined table 47 is provided at the connection between the placing table 2 and the positioning table 6, and a guide housing 3 for limiting and guiding the climbing pipe fitting 4 is provided on the inclined table 47.

[0036] Preferably, the climbing pipe fittings 4 to be welded are placed on the placing table 2 and the inclined table 47 in sequence, and the guide housing 3 provided on the inclined table 47 conducts guiding and transmission. Since the inclined table 47 and the guide housing 3 are obliquely arranged, the climbing pipe fittings 4 are placed obliquely one by one on the inclined table 47. When positioning and welding the climbing pipe fittings 4, the output shaft of the second motor 23 drives, and under the synchronous driving action of the synchronous belt 22, the rotating link 15 on the second connecting shaft 18 is driven to rotate. And due to the eccentric rotation setting of the eccentric wheel 19 and the traction driving action of the collar 20 and the docking rod 21, the rotating links 15 on both sides of the transfer plate 8 are driven to rotate synchronously in a traction manner. Thus, the first support block 9 on the transfer plate 8 can support the climbing pipe fitting 4 at the bottom of the inclined table 47 for material transfer and placement. Whenever the first support block 9 migrates the climbing pipe fitting 4 to the docking position between the next positioning block 7 and the positioning block 7, with the synchronous driving of the collar 20 and the docking rod 21 and the traction rotation action of the rotating link 15, the second support block 10 can support and lift up and conduct material transfer processing on the climbing pipe fitting 4 placed at the docking position between the positioning block 7 and the positioning block 7. Thus, the first support block 9 and the second support block 10 can successively push out the climbing pipe fittings 4 for material transfer and placement, and the second support block 10 can be adaptively adjusted according to the welding position. The specific operation method is as follows: the output shaft of the first motor 14 drives the worm 13 to rotate, and under the meshing connection relationship between the worm 13 and the worm gear 12, the first bidirectional lead screw 11 is driven to rotate, so that the position of the second support block 10 can be linearly adjusted and controlled according to the rotation of the first bidirectional lead screw 11, thus facilitating the welding processing of the subsequent welding robot 5.

[0037] This method of positioning and placing pipe fittings for welding eliminates the need for repeated adjustment of tooling or fixtures, significantly shortening the welding preparation time. It also supports parallel operations, that is, after multiple pipe fittings are positioned and welded to form an overall module, subsequent welding can be carried out simultaneously at different workstations, significantly improving production efficiency while reducing labor costs, simplifying the operating process, reducing dependence on highly skilled welders, shortening the training cycle, and extending the life of the equipment. This standardized positioning welding process reduces the loss caused by frequent equipment adjustments.

[0038] It should be particularly noted that the second connecting shaft 18 and the output shaft of the second motor 23 are both provided with pulleys which are synchronously connected with the synchronous belt 22 . Example

[0039] like Figures 1 to 11 As shown, based on Example 1, this embodiment further includes a welding clamping and positioning mechanism, which is installed on the support plate 24 and is used to position and clamp the support pipe 48 to connect with the climbing pipe 4 for welding. The welding clamping and positioning mechanism includes a clamping seat 32 for adapting to the clamping support pipe 48 and a support plate 24 for controlling the linear movement of the support pipe 48. The support plate 24 is linearly connected to the base plate 1. The support plate 24 is fixedly connected to the piston rod of the first electric push rod 25. The first electric push rod 25 is fixedly installed on the base plate 1. The clamping seat 32 is provided with a clamping claw 33 for clamping and positioning the support pipe 48.

[0040] Furthermore, the welding clamping and positioning mechanism also includes a third bidirectional screw rod 35 and a movable ring 38 for driving the clamping jaws 33 to perform positioning and clamping. The third bidirectional screw rod 35 is rotatably connected to the support seat 45 through a rotating column 44. The support seat 45 is fixedly connected to the lifting block 30. The movable ring 38 is threadedly connected to the third bidirectional screw rod 35. The third bidirectional screw rod 35 is penetrated by the clamping jaw 33. The clamping jaw 33 is provided with a slot hole for avoiding the third bidirectional screw rod 35. The movable ring 38 is slidably connected to the inside of the clamping seat 32 through a slider 39. A second slide groove 40 adapted for sliding connection with the slider 39 is provided in the clamping seat 32. The movable ring 38 is movably connected to one side of the clamping jaw 33. The lifting block 30 is movably installed on the movable block 29 for lifting and lowering. A second electric push rod 31 for controlling lifting and lowering is provided at the connection between the lifting block 30 and the movable block 29.

[0041] Furthermore, the welding clamping and positioning mechanism further includes a first spring 42 and a second spring 43 for resetting and clamping the docking jaw 33. The jaw 33 is rotatably connected to the clamping seat 32 through a third connecting shaft 34. A limiting slide plate 36 is fixedly connected to the middle of the third bidirectional lead screw 35. A first chute 37 adapted for sliding connection with the limiting slide plate 36 is provided in the clamping seat 32. A limiting plate 41 is fixedly connected to one end of the third bidirectional lead screw 35. A first spring 42 is provided at the connection between the limiting plate 41 and the jaw 33. A second spring 43 is provided at the connection between the rotating column 44 and the jaw 33. One end of the rotating column 44 is fixedly connected to a control rod 46.

[0042] Furthermore, the welding clamping and positioning mechanism further includes a third motor 28 for driving the clamping seat 32 to perform linear movement control. The moving block 29 is limited and slidably connected to the support plate 24 through a guiding slide rod 26, and the moving block 29 is threadedly connected to the second bidirectional lead screw 27. The second bidirectional lead screw 27 is rotatably connected to the support plate 24. The second bidirectional lead screw 27 is fixedly connected to the output shaft of the third motor 28. The third motor 28 is fixedly installed outside the support plate 24.

[0043] Preferably, in this embodiment, whenever a certain number of climbing pipe fittings 4 are equidistantly placed at the positioning blocks 7 on the positioning table 6, and according to the height and position to be welded, the second electric push rod 31 drives the support pipe fitting 48 clamped on the clamping seat 32 to perform height control of lifting. The output shaft of the third motor 28 drives the second bidirectional lead screw 27 to rotate. Under the threaded connection between the second bidirectional lead screw 27 and the moving block 29 and the limiting and guiding action of the guiding slide rod 26, the clamping seat 32 can be correspondingly driven to change its position, so as to facilitate the corresponding clamping control process according to the length of the support pipe fitting 48.

[0044] When clamping and positioning the support pipe fitting 48 to be welded, the rotation control lever 46 is adjusted to drive the rotation of the third bidirectional lead screw 35 on the rotating column 44. Since the moving ring 38 is threadedly connected to the third bidirectional lead screw 35, and the third bidirectional lead screw 35 passes through the clamping jaw 33, and the clamping jaw 33 is provided with a slot for avoiding the third bidirectional lead screw 35, thus under the moving connection of the moving ring 38 and the elastic control of the first spring 42 and the second spring 43 on both sides of the clamping jaw 33, the clamping jaw 33 can be correspondingly driven to rotate around the third connecting shaft 34, so as to complete the clamping control operation of the support pipe fitting 48 by the clamping jaw 33. This elastic control method through the movement of the moving ring 38 and the first spring 42 and the second spring 43 can well complete the clamping control operation of the support pipe fitting 48, thus facilitating the subsequent butt joint and welding operation between the support pipe fitting 48 and the climbing pipe fitting 4 placed in position. The first electric push rod 25 can correspondingly push the support pipe fitting 48 placed in position on the clamping seat 32 for moving butt joint welding treatment, without the need for manual adjustment of the positions of the climbing pipe fitting 4 and the support pipe fitting 48 multiple times for welding, thus significantly improving the work efficiency.

[0045] Through this clamping and position adjustment method, it is convenient to adapt to the requirements of different pipe diameters and spatial layouts, realizing flexible adjustment and use with multiple degrees of freedom. At the same time, it is convenient for quick positioning and locking treatment, avoiding product damage caused by offset during subsequent welding, and significantly reducing the auxiliary working hours. That is, through this automatic clamping control method, the work efficiency has been significantly improved compared with the traditional manual operation method, facilitating welding processing and use.

[0046] It should be particularly noted that the components in this application are all common standard components or components well-known to those skilled in the art, and it effectively solves the technical problems proposed in the background art.
