[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 A sports equipment welding device comprises a workbench 11, a rotating sleeve 45 is fixedly connected to the outer surface of the upper end of the workbench 11, a movable rod 14 is rotatably connected to the inner surface of the rotating sleeve 45, and a swing component is arranged on the outer surface of the movable rod 14;

[0034] The swing assembly includes a movable part and a positioning part, the movable part includes a cavity 33 embedded in the outer surface of the lower end of the workbench 11, the inner surface of the cavity 33 is fixedly connected with a slide rod 28, the outer surface of the slide rod 28 is slidably connected with a movable plate 27, the outer surface of the movable plate 27 is symmetrically provided with movable grooves 30, the outer surface of the lower end of the movable rod 14 is magnetically adsorbed with a magnetic sleeve 46, the outer surface of the lower end of the magnetic sleeve 46 is fixedly connected with a swing rod 29, the outer surface of the lower end of the swing rod 29 is fixedly connected with a fixed shaft 31, the fixed shaft 31 is located on the inner side of the movable groove 30 and is in sliding contact with the inner surface of the movable groove 30, the swing assembly is used to swing and adjust the angle of the workpiece.

[0035] The positioning portion includes a support frame 23 fixedly connected to the outer surface of the movable rod 14, and a pointing plate 36 is fixedly connected to the outer surface of the lower end of the support frame 23. The outer surface of the upper end of the workbench 11 is located outside the rotating sleeve 45 and has a scale line 35. The scale line 35 is annular, and the pointing plate 36 is located on the upper side of the scale line 35. The magnetic sleeve 46 is made of an electromagnet. A clamping assembly is arranged on the upper side of the movable rod 14, and the clamping assembly includes a fixed sleeve 15 fixedly connected to the upper end of the movable rod 14.

[0036] By adopting the above technical scheme, when welding and processing sports equipment such as single and double bars, squat racks and barbell racks, it is necessary to adjust the workpiece to be welded to an appropriate angle according to the specifications and shapes of the sports equipment. For this purpose, a swing assembly is provided. During operation, the clamping assembly on the upper side of the movable rod 14 clamps and fixes the workpiece through the fixed sleeve 15, and the workbench 11 rotatably supports the movable rod 14 through the rotating sleeve 45, so that the movable rod 14 can rotate smoothly. When the angle of the workpiece needs to be adjusted, the operator moves the movable plate 27 along the outer surface of the sliding rod 28, and the sliding rod 28 inside the cavity 33 can guide and support the movable plate 27, so that the movable plate 27 can slide linearly. When the movable plate 27 moves to the front side, the movable plate 27 pulls the fixed shaft 31 through the movable groove 30. During the movement, the movable plate 27 will drive the fixed shaft 31 to slide along the inside of the movable groove 30. As the fixed shaft 31 moves, the fixed shaft 31 will drive the swing rod 29 to swing, so that the angle between the swing rod 29 and the movable plate changes accordingly, and the swing rod 29 and the movable rod 14 are magnetically adsorbed through the magnetic sleeve 46, so that the swing rod 29 drives the movable rod 14 to rotate synchronously through the magnetic sleeve 46, and the movable rod 14 drives the workpiece to swing through the fixed sleeve 15, so that the angle between the two groups of workpieces can be flexibly adjusted, which effectively improves the convenience of operation of the welding device. When one group of workpieces needs to remain stationary, the operator cuts off the power of the group of magnetic sleeves 46, so that the magnetic sleeves 46 and the movable rod 14 rotate. By setting the magnetic sleeves 46, the two groups of movable rods 14 can be rotated synchronously or separately, so that the angle between the two groups of workpieces can be better adjusted, thereby further improving the application range of the sports equipment welding device;

[0037] During the rotation process, the movable rod 14 will drive the pointing plate 36 to move synchronously through the support frame 23. The pointing plate 36 is located on the upper side of the scale line 35, and the scale line 35 is pointed by the pointing plate 36. The pointing plate 36 cooperates with the scale line 35 to observe and measure the rotation angle of the movable rod 14, thereby effectively improving the rotation accuracy of the movable rod 14. By improving the assembly accuracy of the workpiece angle, the welding quality of the sports equipment can be further improved.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the movable rods 14, the support frames 23, the scale lines 35 and the pointing plates 36 are all in two groups and are symmetrically distributed. The rear side of the upper outer surface of the workbench 11 is fixedly connected to a fixed plate 12, the front end outer surface of the fixed plate 12 is fixedly connected to a welding machine 13, and the sliding rods 28 are in two groups and are symmetrically distributed.

[0039] A driving assembly is provided on the outside of the movable plate 27, and the driving assembly includes a connecting plate 32 fixedly connected to the outer surface of the lower end of the movable plate 27, a screw rod 26 spirally connected to the outer surface of the connecting plate 32, a rear end of the screw rod 26 is rotatably connected to the inside of the cavity 33, a front end of the screw rod 26 passes through the front side of the workbench 11 and is rotatably connected to the workbench 11, a movable disk 25 is fixedly connected to the front end of the screw rod 26, and the driving assembly is used to drive the swing assembly to start operation.

[0040] By adopting the above technical scheme, the workbench 11 fixes and supports the welding machine 13 through the fixed plate 12, and the operating table performs welding operations on the workpiece by operating welding. In the present application, the welding machine 13 adopts the publicly available existing technology, so its specific structure and working principle are no longer described in detail. In order to improve the operating convenience and operating accuracy of the swing component, a driving component is set. When working, the operator drives the screw rod 26 to rotate synchronously through the movable disk 25, and the connecting plate 32 is connected to the screw rod 26 through a spiral transmission. As the screw rod 26 rotates, the connecting plate 32 will be driven to move along the axial direction of the screw rod 26. During the movement, the connecting plate 32 will drive the movable plate 27 to move synchronously, so that by adjusting the moving distance of the movable plate 27, the swing angle of the movable rod 14 can be effectively adjusted, and then the welding accuracy of the sports equipment can be further improved.

[0041] like Figure 1 , Figure 4 and Figure 6 As shown, a limiting assembly is provided on the upper side of the workbench 11, and the limiting assembly includes positioning holes 34 opened on the outer surface of the upper end of the workbench 11. The number of the positioning holes 34 is several groups and distributed in a ring array. The positioning holes 34 are distributed on the outside of the movable rod 14, and the outer surface of the support frame 23 is provided with a mounting groove 39.

[0042] The positioning rod 38 is slidably connected to the inner side of the mounting groove 39, the upper end of the positioning rod 38 is fixedly connected to the mounting rod 37, the lower end of the positioning rod 38 is engaged with the inner side of the positioning hole 34, the outer surface of the support frame 23 is fixedly connected to the pull rod 44, the end of the pull rod 44 away from the support frame 23 is fixedly connected to the movable rod 14, and the limiting assembly is used to limit and fix the movable rod 14.

[0043] By adopting the above technical solution, when the workpiece moves to an appropriate angle, it is necessary to keep the workpiece still to reduce the probability of deviation during the welding process of the workpiece. For this purpose, a limit assembly is set. When the swing assembly is running, the positioning rod 38 is lifted upward by the mounting rod 37, and the positioning rod 38 slides upward inside the mounting groove 39, so that the lower end of the positioning rod 38 is out of contact with the positioning hole 34 on the surface of the workbench 11, and the support frame 23 is driven to rotate synchronously by the movable rod 14. The pull rod 44 between the movable rod 14 and the support frame 23 is used to pull and support the support frame 23, thereby improving the support strength of the support frame 23. When the movable rod 14 moves to After reaching the appropriate angle, the positioning rod 38 is lowered again so that the lower end of the positioning rod 38 is engaged with the inside of the positioning hole 34. The mounting rod 37 can have a good limiting effect on the positioning rod 38, so that the moving distance of the positioning rod 38 is kept within an appropriate range. By setting a limiting component, the positioning rod 38 and the positioning hole 34 are engaged and limited, which can effectively and quickly block and limit the support frame 23 and the movable rod 14, so that the movable rod 14 and the support frame 23 can remain stationary during the welding process, reducing the probability of accidental rotation of the movable rod 14 and the support frame 23, thereby further reducing welding errors and improving the welding accuracy of sports equipment.

[0044] like Figure 2 and Figure 5 As shown, a retaining ring 16 is fixedly connected to the inner surface of the fixing sleeve 15 , and a guide plate 17 is fixedly connected to the inner surface of the fixing sleeve 15 . The guide plate 17 is distributed in a circular ring shape, and the outer surface of the guide plate 17 is inclined.

[0045] The outer surface of the guide plate 17 is provided with a guide groove 18, the inner surface of the guide groove 18 is slidably connected to a slider 24, the outer surface of the slider 24 is fixedly connected to a guide block 22, and the guide block 22 is in sliding contact with the outer surface of the guide plate 17. The guide grooves 18, guide blocks 22 and sliders 24 are all in several groups and are distributed in a ring array.

[0046] The inner surface of the fixed sleeve 15 is fixedly connected with a spiral seat 21, and the spiral seat 21 is in a circular ring shape. The outer surface of the spiral seat 21 is spirally connected with a locking sleeve 20. The spiral seat 21 is in active contact with the outer surface of the guide block 22. The outer surface of the guide block 22 is fixedly connected with a contact plate 19, and the contact plate 19 is in an arc shape. The number of the contact plates 19 is several groups and distributed in a ring array. The outer surface of the spiral seat 21 is away from the guide block 22 and penetrates to the outside of the fixed sleeve 15. The clamping assembly is used to clamp the workpiece.

[0047] By adopting the above technical solution, the workpiece needs to be stably clamped before welding to improve the welding quality. When the clamping assembly is working, the movable rod 14 fixes and supports the fixed sleeve 15, and the workpiece to be welded passes through the middle of the fixed sleeve 15. The retaining ring 16 can increase the structural strength of the fixed sleeve 15. The fixed sleeve 15 fixes and supports the spiral seat 21, and then the operator rotates the locking sleeve 20. The locking sleeve 20 is connected to the spiral seat 21 through a spiral transmission. As the locking sleeve 20 rotates, it will gradually move along its axial direction. During the movement, the locking sleeve 20 will drive the guide block 22 to move synchronously. The locking sleeve 20 pushes several groups of annularly distributed guide blocks 22 to slide along the surface of the guide plate 17. During the movement, the guide block 22 will drive the slider 24 The guide block 22 is slidably guided inside the guide groove 18, and the guide groove 18 opened on the surface of the guide plate 17 cooperates with the slider 24, so that the guide block 22 can only slide linearly along the surface of the guide plate 17. As the guide block 22 gradually moves, the guide block 22 will drive the contact plate 19 to gather toward the center of the fixed sleeve 15, so that the contact plate 19 and the workpiece surface are kept in close contact, and the workpiece is stably clamped by a plurality of groups of contact plates 19 distributed in an annular array. The arc-shaped surface of the contact plate 19 can have a good clamping effect on workpieces of various specifications such as round and rectangular shapes. While improving the stability of workpiece clamping, it can also effectively improve the application range of the clamping component, thereby further improving the welding quality of sports equipment.

[0048] like Figure 4 and Figure 7 As shown, a buffer assembly is provided at the upper end of the support frame 23, and the buffer assembly includes a buffer groove 40 opened on the inner side of the support frame 23, a spring 42 is fixedly connected to the lower end of the inner surface of the buffer groove 40, a buffer block 41 is fixedly connected to the upper end of the spring 42, the lower side of the outer surface of the buffer block 41 is slidably connected to the inside of the buffer groove 40, a support plate 43 is fixedly connected to the upper end of the buffer block 41, and the support plate 43 is arc-shaped. The buffer assembly is used to lift and support the workpiece.

[0049] By adopting the above technical scheme, for some workpieces with longer lengths, a buffer assembly is set up to improve the clamping quality of the workpiece. After the clamping assembly clamps one end of the workpiece, the other end will be placed on the upper side of the support plate 43. The support frame 23 fixedly supports the support plate 43 through the buffer block 41, and the support frame 23 slidingly supports the buffer block 41 through the buffer groove 40, so that the buffer block 41 can slide linearly along the inside of the buffer groove 40, and then the height of the support plate 43 can be adjusted. The spring 42 inside the buffer groove 40 will apply a certain elastic force to the buffer block 41, and the gravity of the workpiece can be shared by the buffer block 41 and the support plate 43, so that the difficulty of clamping the workpiece can be reduced to a certain extent, and at the same time, the clamping stability of the workpiece can be effectively improved, so as to better stably clamp longer workpieces, thereby effectively ensuring the welding processing quality of sports equipment such as single and double bars.

[0050] Instructions for use: When welding sports equipment, the workpiece to be welded is passed through the middle of the fixed sleeve 15, and then the operator rotates the locking sleeve 20. As the locking sleeve 20 rotates, it will gradually move along its axial direction, and the locking sleeve 20 pushes a plurality of groups of annularly distributed guide blocks 22 to slide along the surface of the guide plate 17. The guide blocks 22 will drive the contact plate 19 to gather toward the center of the fixed sleeve 15, so that the contact plate 19 and the workpiece surface are kept in close contact to clamp the workpiece, and the other end of the workpiece will be placed on the upper side of the support plate 43. The gravity of the workpiece can be shared by the buffer block 41 and the support plate 43. The operator drives the spiral rod 26 to rotate synchronously through the movable disk 25, and the spiral rod 26 drives the movable plate 27 to move linearly through the connecting plate 32. The movable plate 27 pulls the fixed shaft 31 through the movable groove 30. During the movement, the movable plate 27 will drive the fixed shaft 31 to slide along the inside of the movable groove 30, and the fixed shaft 31 will drive the swing rod 29 to swing, so that the swing rod 29 drives the movable rod 14 to rotate synchronously through the magnetic sleeve 46, and the movable rod 14 drives the workpiece to swing through the fixed sleeve 15, so that the angle between the two groups of workpieces can be flexibly adjusted, and the pointing plate 36 cooperates with the scale line 35 to observe and measure the rotation angle of the movable rod 14, so as to effectively improve the rotation accuracy of the movable rod 14. When the workpiece moves to an appropriate angle, the positioning rod 38 and the positioning hole 34 are engaged and limited to effectively block and limit the support frame 23 and the movable rod 14, so that the movable rod 14 and the support frame 23 can remain stationary during the welding process, reducing the probability of accidental rotation of the movable rod 14 and the support frame 23.
