Description

Technical Field

[0001] The present invention belongs to the technical field of fitness equipment processing, and particularly relates to a welding tooling for a fitness bracket. Background Art

[0002] The scope of fitness is very broad, and sports are just one part of fitness. Fitness is generally divided into equipment exercise and non-equipment exercise. Equipment exercise is also a way for many men and women to shape their perfect figures. Modern men and women all like this sport. In the manufacturing process of fitness equipment, welding tooling is often required to improve the welding convenience of the fitness equipment bracket.

[0003] Before welding the existing fitness equipment brackets, it is often necessary to manually adjust the bracket components to the middle part of the processing table to facilitate the welding device to weld the fitness equipment bracket components. However, manually adjusting the position of the fitness equipment bracket components is neither accurate nor can it improve the welding efficiency; and when welding the fitness bracket, the inclination angle of the fitness bracket during the welding process cannot be freely adjusted, so it is impossible to ensure that the welding device can conveniently weld the welding parts at different angles of the fitness bracket; at the same time, when welding the cross bar and the vertical bar of the fitness bracket, it is difficult for the welding device to weld the two sides and the bottom of the connection between the cross bar and the vertical bar, thereby reducing the welding convenience provided by the fitness bracket welding tooling. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a welding tooling for a fitness bracket.

[0005] The technical solution adopted to solve the above technical problem is: a welding tooling for a fitness bracket, including a processing table as an installation carrier. A position adjustment mechanism is provided at the top of the processing table. Both ends of the top of the position adjustment mechanism are provided with a centering clamping mechanism. A fixing mechanism is provided at the middle position above the processing table. An inclination angle adjustment mechanism is provided inside the fixing mechanism. A rotation adjustment mechanism is provided outside the fixing mechanism. A lifting mechanism that cooperates with the rotation adjustment mechanism is jointly provided at the middle positions on both sides of the top of the processing table. A control panel is installed on one side of the top of the processing table. A strip-shaped through groove is opened at the middle position of the top of the processing table.

[0006] Furthermore, the position adjustment mechanism includes a first bidirectional screw rod, which is provided with two groups, and bearing seats are symmetrically installed at both ends of the outer sides of the two groups of first bidirectional screw rods, the bottom of the bearing seat is fixedly connected to the top of the processing table, and one end of the top of the processing table is provided with a first driving device that drives the two groups of first bidirectional screw rods to rotate synchronously, and the two ends of the outer sides of the two groups of the first bidirectional screw rods are symmetrically threaded with moving tables, and baffles are symmetrically installed at the ends of the tops of the two groups of moving tables that are away from each other, and sliding grooves are symmetrically opened on both sides of the two ends of the top of the processing table, and sliders that cooperate with the sliding grooves are symmetrically installed on both sides of the bottom of the moving table.

[0007] Through the above technical solution, the first driving device is controlled to drive the two groups of first bidirectional screws to rotate synchronously. During the process, the slider slides in the slide groove, and the thread action is used to force the two groups of movable platforms to approach each other synchronously, so that the baffles on the two groups of movable platforms push the fitness bracket cross bar to the horizontal middle position above the processing table, thereby helping the subsequent welding device to accurately weld the two ends of the fitness bracket.

[0008] Furthermore, the first driving device includes a first servo motor, and synchronous wheels are symmetrically installed on the same end of the outer sides of the two groups of first bidirectional screw rods, and a synchronous belt is commonly provided on the outer sides of the two groups of synchronous wheels. The output end of the first servo motor is transmission-connected to one end of an adjacent group of first bidirectional screw rods.

[0009] Through the above technical solution, the first servo motor is controlled to drive a connected group of first bidirectional screw rods to rotate, and the two groups of first bidirectional screw rods are connected by synchronous wheels and synchronous belt transmissions, so that the first servo motor can drive the two groups of first bidirectional screw rods to rotate synchronously in the same direction, and then use the thread action to force the two groups of moving platforms to approach or move away from each other.

[0010] Furthermore, the centering clamping mechanism includes a mounting groove, which is located in the middle position of the bottom of the movable platform. A second servo motor is installed at the inner top of the mounting groove, and the output end of the second servo motor extends to the top of the movable platform and is installed with a turntable. An arc-shaped guide hole is symmetrically opened in the center of the top of the turntable, and clamping components that cooperate with the arc-shaped guide holes are symmetrically arranged on both sides of the top of the movable platform.

[0011] Through the above technical solution, the second servo motor is controlled to drive the turntable to rotate clockwise, and the arc-shaped guide hole is used in conjunction with the clamping component to clamp and fix one end of the fitness bracket cross bar on the turntable, and the fitness bracket cross bar is placed in the longitudinal middle position above the processing table, thereby helping to further improve the accuracy of the welding device in welding the two ends of the fitness bracket.

[0012] Further, the clamping assembly includes strip-shaped slots. There are two groups of strip-shaped slots, and the two groups of strip-shaped slots are symmetrically opened at the middle positions on both sides of the moving platform. On both sides of the top of the moving platform, first limiting through holes communicating with the tops of the strip-shaped slots are symmetrically opened. A moving strip is inserted into the interior of the strip-shaped slot, and on the mutually remote sides of the tops of the two moving strips, limiting posts adapted to the first limiting through holes are symmetrically installed. The top ends of the limiting posts pass through the first limiting through holes and the arc-shaped guiding holes and then are installed with first clamping plates.

[0013] Through the above technical solution, when the second servo motor drives the turntable to rotate clockwise, the arc-shaped guiding hole forces the limiting post to slide inside it and gradually approach the central position of the turntable. In this way, the two first clamping plates can clamp and fix one end of the fitness bracket. During the process, the moving strip slides inside the strip-shaped slot, and the limiting post moves in the first limiting through hole. When the turntable rotates counterclockwise, the two first clamping plates can move away from each other.

[0014] Further, the fixing mechanism includes a U-shaped frame. The U-shaped frame is located at the middle position above the processing platform. At the tops of the two sides inside the U-shaped frame, two groups of second bidirectional lead screws are jointly arranged. At both ends of the outer sides of the second bidirectional lead screws, connecting bearings are symmetrically installed, and the outer rings of the connecting bearings are fixedly connected to the inner walls of the U-shaped frame. At both ends of the outer sides of the two groups of second bidirectional lead screws, mutually cooperating second clamping plates are symmetrically arranged in a threaded manner. A second driving device for driving the two groups of second bidirectional lead screws to rotate synchronously is arranged at the top of the U-shaped frame.

[0015] Through the above technical solution, control the second driving device to drive the two groups of second bidirectional lead screws to rotate synchronously, and use the threaded action to force the two groups of second clamping plates to approach each other, so that the two groups of second clamping plates can clamp and fix the middle part of the cross bar of the fitness bracket, which helps to improve the stability during the lifting or tilting angle adjustment of the cross bar of the fitness bracket.

[0016] Further, the second driving device includes a third servo motor. The third servo motor is located at the middle position at the top of the U-shaped frame. At the middle positions of the outer sides of the two groups of second bidirectional lead screws, worm wheels are symmetrically installed. The output end of the third servo motor extends into the interior of the U-shaped frame and is installed with a worm that meshes with the two worm wheels.

[0017] Through the above technical solution, control the third servo motor to drive the worm to rotate, and the worm cooperates with the worm wheels to drive the two groups of second bidirectional lead screws to rotate synchronously, so that the two groups of second clamping plates can be freely controlled to approach or move away from each other.

[0018] Further, the inclination angle adjusting mechanism includes a circular through hole located at the middle position of the second clamping plate. At the bottom ends of the two sides of the second clamping plate away from each other, fourth servo motors are symmetrically installed, and the output ends of the fourth servo motors pass through the second clamping plate and are installed with clamping circular plates. At the bottom ends of the two sides of the two clamping circular plates close to each other, support cross bars are symmetrically installed. A connecting gear is installed on the outer ring of the clamping circular plate. At the middle position inside the U-shaped frame, a wide gear meshing with the two connecting gears is provided, and the wide gear passes through the circular through holes on the two second clamping plates.

[0019] Through the above technical solution, when the two second clamping plates approach each other, the two clamping circular plates can clamp and fix the middle part of the cross plate of the fitness bracket, and the two support cross bars can provide support for the cross plate of the fitness bracket. Then, control the fourth servo motor to drive the clamping circular plate to rotate at any angle, and the two clamping circular plates can rotate synchronously through the wide gear and the connecting gear. In this way, the cross plate of the fitness bracket can be controlled to tilt at any angle, which is convenient for the welding device to weld and process the fitness bracket. The circular through hole enables the second clamping plate not to affect the rotation of the wide gear.

[0020] Further, the rotation adjusting mechanism includes a rotating ring. The U-shaped frame is installed inside the rotating ring. At both ends of the outer ring of the rotating ring, rotating bearings are symmetrically installed. The outer rings of the two rotating bearings are jointly installed with a fixed ring. At one end of the outer ring of the rotating ring, a driven gear is installed. On the outside of the fixed ring, a fifth servo motor is installed, and the output end of the fifth servo motor is installed with a driving gear meshing with the driven gear.

[0021] Through the above technical solution, control the fifth servo motor to rotate. By driving the rotation of the driving gear and the driven gear, the rotating ring inside the fixed ring can be stably rotated 90° each time. In this way, the rotation angle of the cross bar of the fitness bracket located between the two clamping circular plates can also be adjusted, which is convenient for the welding device to weld and process. After the rotating ring rotates 270°, rotate it back to the original position in the reverse direction to avoid the power supply line winding.

[0022] Further, the lifting mechanism includes two vertical brackets symmetrically installed at the middle positions on both sides of the top of the processing table. A second limit through hole is provided on the outer side of the vertical bracket. At the bottom ends of the outer sides of the two vertical brackets, electric telescopic rods are symmetrically installed, and the output ends of the electric telescopic rods are installed with connecting blocks. One side of the connecting block passes through the second limit through hole and is fixedly connected to the outside of the fixed ring.

[0023] Through the above technical solution, the electric telescopic rod is controlled to extend, and the two groups of electric telescopic rods drive the fixed ring located between the two vertical brackets to rise synchronously through the connecting block. In this way, the height of the crossbar of the fitness bracket clamped and fixed by the two clamping circular plates can be adjusted, which not only helps to meet the welding height requirement of the welding device, but also facilitates the height requirement when the rotation adjustment mechanism rotates the crossbar of the fitness bracket.

[0024] The beneficial effects of the present invention are as follows: (1) Through the cooperation of the position adjustment mechanism and the centering clamping mechanism, the crossbar and the vertical rod of the fitness bracket can be both in the exact middle position above the processing table, and the two vertical rods of the fitness bracket can be automatically aligned and fitted with both ends of the crossbar, thus facilitating the welding device to weld and fix the vertical rod and the crossbar; (2) Through the fixing mechanism, the crossbar of the fitness bracket located in the exact middle position above the processing table can be fixed. Then, by using the cooperation of the inclination angle adjustment mechanism and the lifting mechanism, the inclination angle of the crossbar of the fitness bracket can be freely adjusted, enabling the welding device to conveniently weld and process the welding parts at different angles of the fitness bracket; (3) After the height of the fitness bracket is increased by the lifting mechanism, the rotation adjustment mechanism can be used to freely adjust the fitness bracket to rotate at any angle, which helps the welding device to weld and process both sides and the bottom of the connection between the vertical rod and the crossbar of the fitness bracket. Moreover, in cooperation with the inclination angle adjustment mechanism that can adjust the inclination angle of the crossbar of the fitness bracket, the welding convenience provided by the welding tooling for the fitness bracket is further improved.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0042] like Figures 1 - 9 As shown, a welding tool for a fitness bracket in this embodiment includes a processing table 1 as a mounting carrier, a position adjustment mechanism 2 is provided on the top of the processing table 1, a control panel 8 is installed on one side of the top of the processing table 1, and a strip-shaped through slot 9 is opened in the middle position of the top of the processing table 1, and the position adjustment mechanism 2 includes a first bidirectional screw rod 202, and the first bidirectional screw rod 202 is provided with two groups, and the two ends of the outer sides of the two groups of first bidirectional screw rods 202 are symmetrically installed with bearing seats 201, and the bottom of the bearing seat 201 is fixedly connected to the top of the processing table 1, and one end of the top of the processing table 1 is provided with a first driving device 203 that drives the two groups of first bidirectional screw rods 202 to rotate synchronously, and the first driving device 203 includes a first servo motor 2033, and the same end of the outer sides of the two groups of first bidirectional screw rods 202 are symmetrically installed with synchronous wheels 2031, and the outer sides of the two groups of synchronous wheels 2031 are commonly provided with a synchronous belt 2032, and the output end of the first servo motor 2033 is transmission-connected to one end of an adjacent group of first bidirectional screw rods 202, and the outer sides of the two groups of first bidirectional screw rods 202 are symmetrically installed with synchronous wheels 2031. The two ends of the side are symmetrically provided with a moving platform 204 with a common thread, and a baffle 205 is symmetrically installed at one end of the top of the two groups of moving platforms 204 away from each other. Slide grooves 206 are symmetrically opened on both sides of the two ends of the top of the processing table 1, and sliders 207 cooperating with the slide grooves 206 are symmetrically installed on both sides of the bottom of the moving platform 204, controlling the first servo motor 2033 to drive a connected group of first bidirectional lead screws 202 to rotate, and the two groups of first bidirectional lead screws 202 are connected by synchronous wheels 2031 and synchronous belts 2032, so that the first servo motor 2033 can drive the two groups of first bidirectional lead screws 202 to rotate synchronously in the same direction, and then use the thread action to force the two groups of moving platforms 204 to approach or move away from each other. During the process, the slider 207 slides in the slide groove 206, and uses the thread action to force the two groups of moving platforms 204 to approach each other synchronously, so that the baffles 205 on the two groups of moving platforms 204 push the fitness bracket cross bar to the horizontal middle position above the processing table 1, thereby helping the subsequent welding device to accurately weld the two ends of the fitness bracket.

[0043] like Figures 1 - 3 and Figures 6 - 9As shown, centering clamping mechanisms 3 are provided at both ends of the top of the position adjustment mechanism 2. The centering clamping mechanism 3 includes an installation groove 301 which is located at the middle position of the bottom of the moving table 204. A second servo motor 302 is installed on the inner top of the installation groove 301, and the output end of the second servo motor 302 extends above the moving table 204 and is equipped with a turntable 303. Arc-shaped guiding holes 304 are symmetrically arranged at the center of the top of the turntable 303. Clamping components 305 which are matched with the arc-shaped guiding holes 304 are symmetrically arranged on both sides of the top of the moving table 204. The clamping component 305 includes strip-shaped slots 3051. There are two groups of strip-shaped slots 3051 which are symmetrically arranged at the middle positions on both sides of the moving table 204. First limiting through holes 3052 which communicate with the tops of the strip-shaped slots 3051 are symmetrically arranged on both sides of the top of the moving table 204. A moving bar 3053 is inserted into the interior of the strip-shaped slot 3051, and limiting posts 3054 which are matched with the first limiting through holes 3052 are symmetrically installed on the mutually remote sides of the tops of the two moving bars 3053. The top ends of the limiting posts 3054 pass through the first limiting through holes 3052 and the arc-shaped guiding holes 304 and are then installed with first clamping plates 3055. Controlling the second servo motor 302 to drive the turntable 303 to rotate clockwise, the arc-shaped guiding holes 304 force the limiting posts 3054 to slide inside them and gradually approach the center position of the turntable 303. In this way, the two first clamping plates 3055 can clamp and fix one end of the fitness bracket. During the process, the moving bar 3053 slides inside the strip-shaped slot 3051, and the limiting post 3054 moves in the first limiting through hole 3052, so that the cross bar of the fitness bracket is placed at the longitudinal middle position above the processing table 1, which helps to further improve the accuracy of the welding device for welding and processing both ends of the fitness bracket.

[0044] As Figures 1 - 3 and Figures 10 - 13As shown in the figure, a fixing mechanism 4 is provided at the middle position above the processing table 1 of this embodiment. The fixing mechanism 4 includes a U-shaped frame 401, which is located at the middle position above the processing table 1. At the top of both sides inside the U-shaped frame 401, two groups of second bidirectional lead screws 402 are jointly provided. At both ends of the outer side of the second bidirectional lead screw 402, connecting bearings 403 are symmetrically installed, and the outer ring of the connecting bearing 403 is fixedly connected to the inner wall of the U-shaped frame 401. At both ends of the outer side of the two groups of second bidirectional lead screws 402, mutually cooperating second clamping plates 404 are symmetrically arranged in a threaded manner. A second driving device 405 for driving the two groups of second bidirectional lead screws 402 to rotate synchronously is provided at the top of the U-shaped frame 401. The second driving device 405 includes a third servo motor 4052, which is located at the middle position of the top of the U-shaped frame 401. At the middle position of the outer side of the two groups of second bidirectional lead screws 402, worm wheels 4051 are symmetrically installed. The output end of the third servo motor 4052 extends into the U-shaped frame 401 and is provided with a worm 4053 that meshes with the two groups of worm wheels 4051. By controlling the third servo motor 4052 to drive the worm 4053 to rotate, the worm 4053 cooperates with the worm wheels 4051 to drive the two groups of second bidirectional lead screws 402 to rotate synchronously. By using the thread action, the two groups of second clamping plates 404 are forced to approach each other, so that the two groups of second clamping plates 404 can clamp and fix the middle part of the cross bar of the fitness bracket, which helps to improve the stability during the lifting or tilting angle adjustment of the cross bar of the fitness bracket.

[0045] As Figures 1 - 3 and Figures 10 - 14As shown, an inclination angle adjusting mechanism 5 is provided inside the fixing mechanism 4 of this embodiment. The inclination angle adjusting mechanism 5 includes a circular through hole 506, which is located at the middle position of the second clamping plate 404. At the bottom ends of the two sides of the second clamping plates 404 away from each other, fourth servo motors 501 are symmetrically installed, and the output ends of the fourth servo motors 501 pass through the second clamping plates 404 and are equipped with clamping circular plates 502. At the bottom ends of the two sides of the two clamping circular plates 502 close to each other, support cross bars 503 are symmetrically installed. A connecting gear 504 is installed on the outer ring of the clamping circular plate 502. At the middle position inside the U-shaped frame 401, a wide gear 505 meshing with the two connecting gears 504 is provided, and the wide gear 505 passes through the circular through holes 506 on the two second clamping plates 404. When the two second clamping plates 404 approach each other, the two clamping circular plates 502 can clamp and fix the middle part of the cross plate of the fitness bracket, and the two support cross bars 503 can provide support for the cross plate of the fitness bracket. Then, control the fourth servo motor 501 to drive the clamping circular plate 502 to rotate at any angle, and the two clamping circular plates 502 can rotate synchronously through the wide gear 505 and the connecting gear 504. In this way, the cross plate of the fitness bracket can be controlled to tilt at any angle, which is convenient for the welding device to weld and process the fitness bracket. The circular through hole 506 enables the second clamping plate 404 not to affect the rotation of the wide gear 505.

[0046] As Figures 1 - 4 , Figure 10 and Figure 15As shown in the figure, a rotation adjustment mechanism 6 is provided on the outside of the fixing mechanism 4 of this embodiment. A lifting mechanism 7 that cooperates with the rotation adjustment mechanism 6 is jointly provided at the middle positions on both sides of the top of the processing table 1. The rotation adjustment mechanism 6 includes a rotating ring 601. The U-shaped frame 401 is installed inside the rotating ring 601. Rotating bearings 602 are symmetrically installed at both ends of the outer ring of the rotating ring 601. A fixing ring 603 is jointly installed on the outer rings of the two groups of rotating bearings 602. A driven gear 604 is installed at one end of the outer ring of the rotating ring 601. A fifth servo motor 605 is installed on the outside of the fixing ring 603, and a driving gear 606 that meshes with the driven gear 604 is installed at the output end of the fifth servo motor 605. The lifting mechanism 7 includes upright brackets 701. There are two groups of upright brackets 701, and the two groups of upright brackets 701 are symmetrically installed at the middle positions on both sides of the top of the processing table 1. A second limit through hole 702 is provided on the outside of the upright bracket 701. Electric telescopic rods 703 are symmetrically installed at the bottom ends on the outside of the two groups of upright brackets 701, and a connecting block 704 is installed at the output end of the electric telescopic rod 703. One side of the connecting block 704 passes through the second limit through hole 702 and is fixedly connected to the outside of the fixing ring 603. First, control the electric telescopic rod 703 to extend. The two groups of electric telescopic rods 703 drive the fixing ring 603 located between the two groups of upright brackets 701 to rise synchronously through the connecting block 704. During the process, the connecting block 704 slides in the second limit through hole 702. In this way, the height of the fitness bracket crossbar clamped and fixed by the two clamping circular plates 502 can be adjusted, which not only helps meet the welding height requirements of the welding device, but also facilitates the height requirements when the rotation adjustment mechanism 6 rotates the fitness bracket crossbar. After that, control the fifth servo motor 605 to rotate, and use the transmission of the driving gear 606 and the driven gear 604 to drive the rotating ring 601 inside the fixing ring 603 to rotate steadily by 90° each time. In this way, the rotation angle of the fitness bracket crossbar located between the two clamping circular plates 502 can also be adjusted, facilitating the welding process of the welding device. After the rotating ring 601 rotates 270°, rotate it back to the original position in the opposite direction to avoid the power supply line from winding.

[0047] The working principle of this embodiment is as follows. First, pass the cross bar of the fitness bracket through between two groups of clamping circular plates 502, and place the two ends of the cross bar of the fitness bracket on two groups of turntables 303. Then, control the first driving device 203 through the control panel 8 to drive two groups of first bidirectional lead screws 202 to rotate synchronously, forcing the two groups of moving platforms 204 to approach each other synchronously until the two groups of baffles 205 move the cross bar of the fitness bracket to the horizontal middle position above the processing table 1. Then, control the second servo motor 302 to drive the turntable 303 to rotate clockwise, so that the two pairs of first clamping plates 3055 respectively clamp the two ends on both sides of the cross bar of the fitness bracket. At this time, the cross bar of the fitness bracket is also located at the longitudinal middle position above the processing table 1. Subsequently, control the second driving device 405 to drive two groups of second bidirectional lead screws 402 to rotate synchronously, so that the two groups of second clamping plates 404 approach each other until the two groups of clamping circular plates 502 cooperate to clamp and fix the middle position of the cross bar of the fitness bracket. Then, control the two groups of moving platforms 204 to move away from each other, and place the two vertical bars of the fitness bracket on the top of the turntable 303 and make them close to the two ends of the cross bar of the fitness bracket. Then, control the two groups of moving platforms 204 to approach each other again, and the baffle 205 pushes the two vertical bars of the fitness bracket to tightly abut against the two ends of the cross bar of the fitness bracket. Then, weld the top of the connection between the cross bar and the vertical bar of the fitness bracket through the welding device. Then, control the electric telescopic rod 703 to extend to lift the height of the cross bar of the fitness bracket. At this time, control the fifth servo motor 605 to cooperate with the driving gear 606 and the driven gear 604 to drive the rotating ring 601 to rotate 90° clockwise each time, so that the two sides and the bottom of the connection between the cross bar and the vertical bar of the fitness bracket are successively rotated upwards, and then weld the remaining unwelded parts of the connection between the cross bar and the vertical bar of the fitness bracket through the welding device. During the process, control the fourth servo motor 501 to drive the clamping circular plate 502 to rotate to adjust the inclination angle of the cross bar of the fitness bracket, so that other parts of the cross bar of the fitness bracket are convenient for welding and processing.

[0048] The above is only a preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention.
