Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device for sports equipment. Background Technology

[0002] Basketball is a very popular sport, and basketball hoops are an essential piece of equipment in basketball games and training. Basketball hoops and rims are usually made of welded steel. Welding is a key process in the production of basketball hoops, and the quality of welding directly affects the production quality of basketball hoops and rims.

[0003] For example, a sports equipment welding device with publication number CN119077257A can effectively reduce the probability of basketball hoop deformation due to heat during the welding process by clamping and fixing the basketball hoop in different directions. This can ensure the levelness and outer curvature of the finished basketball hoop weld, thereby effectively ensuring the welding accuracy of the basketball hoop. At the same time, it can also reduce the workload of subsequent adjustment and correction of the roundness of the basketball hoop, thus reducing the processing cost of basketball hoop welding to a certain extent. However, in actual use, basketball hoops are usually welded from four seamless steel pipes during the production process. By adopting multi-segment welding, the stress can be distributed through optimized joint design, reducing local high stress concentration, thereby extending the service life. In basketball, players' shooting, dunking and other actions will generate frequent dynamic impacts. Multi-segment welded structures can enhance the frame's ability to absorb dynamic loads by rationally arranging the weld positions, avoiding overall structural failure due to the fracture of a single weld. Multi-segment welding can control the local heating range, reducing thermal stress concentration and residual deformation caused by single welding. Currently, when welding basketball hoops, the welding process mainly involves butt welding two steel pipes together, butt welding multiple steel pipes separately, and then splicing them together. This welding efficiency is low, as it is not possible to weld multiple steel pipes continuously, resulting in low production efficiency of the basketball hoop and an inability to guarantee the precision of the butt joints, leading to low welding quality and certain defects in its use.

[0004] Therefore, we propose a welding device for sports equipment to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for sports equipment to solve the problems mentioned in the background art, which are that when welding basketball hoops, the welding process mainly involves butt welding two steel pipes together, welding multiple steel pipes together separately, and then splicing them together. This results in low welding efficiency, the inability to continuously weld multiple steel pipes, low production efficiency of basketball hoops, and the inability to guarantee the accuracy of the butt joints, leading to low welding quality.

[0026] Preferably, a limiting frame is fixedly installed inside the upper part of the box, and a ventilation slot is opened through the top of the box.

Two sets of positioning strips are symmetrically installed inside the lower part of the box, and four positioning strips are symmetrically arranged on the left and right sides of each set. An activated carbon mesh and a filter screen are respectively arranged between the two positioning strips.

[0027] By adopting the above technical solution, it is possible to purify the fumes generated during welding.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: This welding equipment for sports equipment allows for the direct placement of seamless steel pipes in corresponding placement slots when welding multiple seamless steel pipes. The movable plate can then automatically move up and down to connect and fix the multiple seamless steel pipes. In the welding of basketball hoops, this avoids the need to weld multiple seamless steel pipes separately, thus reducing work efficiency. Furthermore, after connecting the seamless steel pipes, the accuracy of the connection can be guaranteed, preventing displacement during the connection process from affecting subsequent welding quality. Simultaneously, after the welding of multiple seamless steel pipes is completed, it is easy to remove the hoops. During removal, a pushing force can be applied to the weld joint of the hoops, and the reliability of the weld can be judged by observing whether there are cracks. Welding defects can be detected in a timely manner, effectively improving the production efficiency of basketball hoops.

[0029] 1. When welding multiple seamless steel pipes, the seamless steel pipes can be placed in the placement groove and placement seat. The placement groove is just the right size to accommodate the seamless steel pipes, without the need for additional adjustment of the pipes' positions. During welding, the electric cylinder can be activated to move the movable plate upwards. After the movable plate moves upwards, it can slide on the positioning rod. Further upward movement of the movable plate can push the placement seat upwards via the movable frame. The upward movement of the placement seat lifts the seamless steel pipes. As the placement seat moves upwards, the movable frame moves the columns between the fixed frames upwards. The columns can move on the inclined section of the guide groove, allowing the columns to move and thus the fixed frames to move. After the movable plate moves upwards, the four movable frames can move closer together. At this point, the four seamless steel pipes are lifted by the placement seat. Simultaneously, the movement of the placement seat allows the ends of the four seamless steel pipes to be joined. During the movement of the placement seat, the movable rod can move. After the placement seat moves a certain distance, the roller abuts against the support plate. Further movement of the placement seat allows the positioning frame to slide on the movable rod, which can drive the rotating rod and rotating gear to move. After the rotating gear moves, it interacts with the gear... The meshing of the bars causes the rotating rod to rotate, which in turn drives the positioning seat to rotate. As the movable plate moves upward, the column moves to the intersection of the inclined and vertical sections of the guide groove, at which point the rotating rod rotates exactly 90 degrees, causing the positioning seat and the placement seat to close. At this point, the four seamless steel pipes can be joined at the ends. Simultaneously, the positioning seat and the placement seat close to secure the seamless steel pipes. Then, the servo motor can be activated to rotate the rotating plate 45 degrees, moving the joint of the seamless steel pipes below the welding torch. The welding can then be controlled by the robotic arm. The welding gun welds seamless steel pipes, and then the servo motor controls the rotating plate to rotate intermittently by 90 degrees to achieve the butt welding of multiple seamless steel pipes. There is no need to weld the seamless steel pipes one by one. The steel pipes can be placed directly in the corresponding placement slots. Then, the movable plate can be moved up to automatically achieve the butt welding and fixation of multiple seamless steel pipes. In the welding work of the basket ring, it avoids the reduction of work efficiency by welding multiple seamless steel pipes separately. After the seamless steel pipes are butt welded, the accuracy of the butt welding can be guaranteed, and the displacement of multiple seamless steel pipes during the butt welding process can be avoided, which will affect the subsequent welding quality.

[0030] 2. After the four seamless steel pipes are welded together, they can form a basket ring. Once welding is complete, the electric cylinder can be activated to move the movable plate upwards, allowing the column rods to slide on the vertical section of the guide groove. At the same time, the roller shafts move upwards together, rotating on the vertical edge of the support plate. The upward movement of the column rods allows them to abut against the top block. As the column rods move upwards, the top block pushes the four column rods away from each other, which in turn pushes the four movable frames away from each other. At this point, the positioning seat and the placement seat close, fixing the welded basket ring. The movement of the movable frames causes the moving rods to slide on the connecting block and stretch the support springs, thus applying pressure to the four placement seats. With the thrust moving away from each other, the support spring supports the placement seats when the four placement seats move closer together, and the connecting block is not easy to slide on the moving rod. At this time, since the basket ring is fixed by the positioning seat and the placement seat, an outward thrust can be applied to the four seamless steel pipes after welding and fixing. The reliability of the welding can be judged by observing whether there are cracks at the welding point. Then the movable plate continues to move upward, and the column rod can pass through the top block. As the movable plate continues to move upward, the roller can contact the inclined edge of the support plate. Under the action of the telescopic spring, the movable rod moves, which can reset and rotate the positioning seat, so that the four positioning seats can open at the same time, which makes it easier to remove the welded basket ring.

[0031] 3. During welding, the welding torch can activate a fan. The fan draws air through the connecting pipe into the annular pipe, allowing the intake pipe to absorb the welding fumes. The fumes enter the annular pipe through the intake pipe and then into the housing through the connecting pipe. Large particles are removed by a filter, and then the fumes pass through an activated carbon screen, which adsorbs harmful substances. An inspection door is located on the front of the housing, secured with screws. Removing the door allows for easy cleaning or replacement of the filter and activated carbon screen, thus purifying the welding fumes and improving practicality. Attached Figure Description

[0047] Four positioning rods 206 are circumferentially and equidistantly installed at the bottom of the rotating plate 203. The movable plate 205 is slidably connected to the positioning rods 206.

[0048] The through groove 209 is provided with a placement seat 210, and a mounting bracket 211 is symmetrically installed on one side of the placement seat 210. The two mounting brackets 211 are rotatably connected to a rotating rod 212. Meanwhile, a connecting bracket 213 is fixedly installed on the middle of the outer side of the rotating rod 212, and a positioning seat 214 is fixedly installed on the top of the connecting bracket 213.

[0049] A movable frame 218 is provided below the placement seat 210, and support rods 219 are symmetrically installed on one side of the movable frame 218. Support blocks 220 are slidably connected to the outside of the two support rods 219, and the support blocks 220 are fixedly connected to the movable plate 205.

[0050] A fixed frame 221 is symmetrically installed on the lower side of the other side of the movable frame 218, and an mounting plate 222 is fixedly installed on the bottom of the rotating plate 203 above the four sets of fixed frames 221. A guide groove 223 is opened through one side of the mounting plate 222. A column rod 2211 is fixedly installed between two fixed frames 221, and the column rod 2211 is slidably connected to the guide groove 223. A top block 224 is symmetrically installed on the upper side of the mounting plate 222 and above the guide groove 223.

[0051] A positioning frame 225 is symmetrically installed on one side of the placement base 210 below the two mounting brackets 211. A movable rod 226 is slidably connected to the upper part of the interior of each of the two positioning brackets 225. Rotating gears 227 are symmetrically installed on both sides of the exterior of the rotating rod 212. At the same time, a rack 228 is fixedly installed at the bottom of each of the two movable rods 226, and the rack 228 is meshed with the rotating gear 227.

[0052] Each of the two positioning frames 225 has a mounting rod 230 fixedly installed on one side below the movable rod 226. A mounting block 229 is slidably connected to the outer side of the mounting rod 230, and the mounting block 229 is fixedly connected to the movable rod 226. At the same time, a telescopic spring 231 is sleeved on the outer side of the mounting rod 230 on the side of the mounting block 229. The two ends of the telescopic spring 231 are fixedly connected to the mounting rod 230 and the mounting block 229, respectively. A mounting seat 232 is fixedly installed on one end of each of the two movable rods 226. A roller 233 is rotatably connected inside the mounting seat 232. At the same time, a support plate 234 is fixedly installed on the top of the rotating plate 203 on one side of each of the four rollers 233.

[0053] Example 1: As Figures 1-6As shown, when welding multiple seamless steel pipes 208, the seamless steel pipes 208 can be placed in the placement groove 207 and the placement seat 210. The size of the placement groove 207 is just enough to accommodate the seamless steel pipes 208, without the need to adjust the position of the seamless steel pipes 208 separately. Then, during welding, the electric cylinder 204 can be activated to drive the movable plate 205 to move upward. After the movable plate 205 moves upward, it can slide on the positioning rod 206. The movable plate 205 continues to move upward, and the movable frame 218 can push the placement seat 210 upward. The upward movement of the placement seat 210 can lift the seamless steel pipes 208. Then, when the placement seat 210 moves upward, the movable frame 218 drives the column rod 2211 between the fixed frame 221 to move upward. 211 can move on the inclined section of the guide groove 223, so that the upward movement of the column rod 2211 can drive the fixed frame 221 to move, so that after the movable plate 205 moves upward, the four movable frames 218 can move closer together. At this time, the four seamless steel pipes 208 are just lifted by the placement seat 210. At the same time, the movement of the placement seat 210 can realize the docking at the ends of the four seamless steel pipes 208. During the movement of the placement seat 210, the movable rod 226 can move. After the placement seat 210 moves a certain distance, the roller 233 abuts against the support plate 234. At this time, the continued movement of the placement seat 210 can make the positioning frame 225 slide on the movable rod 226, which can drive the rotating rod 212 and the rotating gear 227 to move. After the rotating gear 227 moves, it meshes with the rack 228, causing the rotating rod 212 to rotate. The rotation of the rotating rod 212 drives the positioning seat 214 to rotate. As the movable plate 205 moves upward, the column rod 2211 moves to the intersection of the inclined and vertical sections of the guide groove 223. The rotating rod 212 rotates exactly ninety degrees, causing the positioning seat 214 and the placement seat 210 to close. At this point, the four seamless steel pipes 208 can be connected end-to-end. During this connection, the positioning seat 214 and the placement seat 210 close to fix the seamless steel pipes 208. Then, the servo motor 201 can be activated to rotate the rotating plate 203 forty-five degrees, moving the connection point of the seamless steel pipes 208 to the welding torch 102. Below, the robotic arm 101 controls the welding torch 102 to weld the seamless steel pipe 208. Then, the servo motor 201 controls the rotating plate 203 to rotate intermittently by 90 degrees, realizing the butt welding of multiple seamless steel pipes 208. There is no need to weld the seamless steel pipes 208 one by one. The steel pipes 208 can be placed directly in the corresponding placement slots 207. Then, the movable plate 205 can move up to automatically realize the butt welding and fixation of multiple seamless steel pipes 208. In the welding work of the basket ring, the separate welding of multiple seamless steel pipes 208 is avoided, which reduces the work efficiency. After the seamless steel pipes 208 are butt welded, the accuracy of the butt welding can be guaranteed, and the displacement of multiple seamless steel pipes 208 during the butt welding process can be avoided, which will affect the subsequent welding quality.

[0054] Each of the two positioning frames 225 has a mounting rod 230 fixedly installed on one side below the movable rod 226. A mounting block 229 is slidably connected to the outer side of the mounting rod 230, and the mounting block 229 is fixedly connected to the movable rod 226. At the same time, a telescopic spring 231 is sleeved on the outer side of the mounting rod 230 on the side of the mounting block 229. The two ends of the telescopic spring 231 are fixedly connected to the mounting rod 230 and the mounting block 229, respectively. A mounting seat 232 is fixedly installed on one end of each of the two movable rods 226. A roller 233 is rotatably connected inside the mounting seat 232. At the same time, a support plate 234 is fixedly installed on the top of the rotating plate 203 on one side of each of the four rollers 233.

[0055] Example 2: Figures 2-3 and Figures 5-7 As shown, after the four seamless steel pipes 208 are welded together, they can form a basket ring. After welding, the electric cylinder 204 can be activated to drive the movable plate 205 to continue moving upward, so that the column rod 2211 can slide on the vertical section of the guide groove 223. At this time, the roller shaft 233 moves upward together and can rotate on the vertical edge of the support plate 234. The column rod 2211 can abut against the top block 224. As the column rod 2211 moves upward, the top block 224 can push the four column rods 2211 away from each other, which in turn pushes the four movable frames 218 away from each other. At this time, the positioning seat 214 and the placement seat 210 are closed, which can fix the welded basket ring. The movement of the movable frame 218 can drive the moving rod 216 to slide on the connecting block 215 and stretch the support spring 217, so that the four placement frames can be moved away from each other. When the four placement seats 210 move closer together, the support spring 217 supports the placement seats 210. The connecting block 215 is not easy to slide on the moving rod 216. At this time, since the basket ring is fixed by the positioning seat 214 and the placement seat 210, the four seamless steel pipes 208 after welding and fixing can be pushed outward. The reliability of the welding can be judged by observing whether there are cracks at the welding point. Then the movable plate 205 continues to move upward. The column rod 2211 can pass through the top block 224. As the movable plate 205 continues to move upward, the roller 233 can contact the inclined edge of the support plate 234. Under the action of the telescopic spring 231, the movable rod 226 moves, which can reset and rotate the positioning seat 214, so that the four positioning seats 214 can open at the same time, which makes it easier to remove the welded basket ring.

[0056] Purification component 3 is positioned above welding torch 102;

[0057] The purification component 3 includes a horizontal plate 301 fixedly installed outside the welding torch 102, and an annular tube 302 fixedly installed at the bottom of the horizontal plate 301. Four air inlet pipes 303 are circumferentially and equidistantly connected to the bottom of the annular tube 302. Meanwhile, a box 304 is fixedly installed on one side of the horizontal plate 301, and a connecting pipe 305 is connected through one side of the annular tube 302. The end of the connecting pipe 305 away from the annular tube 302 passes through the horizontal plate 301 and is connected through the box 304.

[0058] A limiting frame 306 is fixedly installed inside the upper part of the box 304, and a ventilation slot is provided through the top of the box 304. An inspection door is provided on the front of the box 304. A fan 307 is fixedly installed inside the limiting frame 306. Two sets of positioning strips 308 are symmetrically installed inside the lower part of the box 304, and four positioning strips 308 are symmetrically arranged on the left and right sides of each set. An activated carbon mesh 309 and a filter screen 310 are respectively arranged between the two positioning strips 308.

[0059] Example 3: Figure 1 and Figures 8-9 As shown, the welding torch 102 can activate the fan 307 during welding. Under the action of the fan 307, air can be drawn from the annular pipe 302 through the connecting pipe 305, allowing the air inlet pipe 303 to adsorb the welding fumes. The welding fumes can enter the annular pipe 302 through the air inlet pipe 303, and then enter the housing 304 through the connecting pipe 305. The fumes can pass through the filter screen 310 to remove large particulate impurities, and then pass through the activated carbon screen 309. The activated carbon can adsorb harmful substances in the fumes. The housing 304 is equipped with an inspection door on the front, which is fixed to the housing 304 with screws. By removing the inspection door, it is easy to clean or replace the filter screen 310 and the activated carbon screen 309. Thus, the welding fumes generated during welding can be purified, improving practicality.

[0060] Working principle: When using this welding equipment for sports equipment, firstly, according to... Figures 1-9As shown, when welding multiple seamless steel pipes 208, the seamless steel pipes 208 can be placed in the placement groove 207 and the placement seat 210. The size of the placement groove 207 is just enough to accommodate the seamless steel pipes 208, without the need for additional adjustment of the position of the seamless steel pipes 208. Then, during welding, the electric cylinder 204 can be activated to move the movable plate 205 upward. After the movable plate 205 moves upward, it can slide on the positioning rod 206. If the movable plate 205 continues to move upward, it can push the placement seat 210 upward through the movable frame 218. The upward movement of the placement seat 210 can lift the seamless steel pipes 208. Then the placement seat 210... When the 10 is moved upward, the movable frame 218 drives the column 2211 between the fixed frames 221 to move upward. The column 2211 can move on the inclined section of the guide groove 223, so that the upward movement of the column 2211 can drive the fixed frame 221 to move. After the movable plate 205 moves upward, the four movable frames 218 can move closer together. At this time, the four seamless steel pipes 208 are just lifted by the placement seat 210. At the same time, the movement of the placement seat 210 can realize the docking at the ends of the four seamless steel pipes 208. During the movement of the placement seat 210, the movable rod 226 can move. After the placement seat 210 moves a certain distance, it can... The roller shaft 233 abuts against the support plate 234. At this time, the placement seat 210 continues to move, allowing the positioning frame 225 to slide on the movable rod 226. This drives the rotating rod 212 and the rotating gear 227 to move. After the rotating gear 227 moves, it meshes with the rack 228, causing the rotating rod 212 to rotate. The rotation of the rotating rod 212 drives the positioning seat 214 to rotate. As the movable plate 205 moves upward, the column rod 2211 moves to the intersection of the inclined section and the vertical section of the guide groove 223. The rotating rod 212 rotates exactly ninety degrees, thereby causing the positioning seat 214 to close with the placement seat 210. At this point, the four seamless steel pipes 208 can be connected at their ends. During the connection, the positioning seat 214 and the placement seat 210 can close to fix the seamless steel pipes 208. At this time, the servo motor 201 can be started to drive the rotating plate 203 to rotate forty-five degrees, so that the connection point of the seamless steel pipes 208 moves to below the welding gun 102. The robotic arm 101 can control the welding gun 102 to weld the seamless steel pipes 208. Afterwards, the servo motor 201 controls the rotating plate 203 to rotate ninety degrees intermittently to achieve the butt welding of multiple seamless steel pipes 208, eliminating the need to butt weld the seamless steel pipes 208 one by one.

[0061] After the four seamless steel pipes 208 are welded together, they can form a basket. After welding, the electric cylinder 204 can be activated to drive the movable plate 205 to continue moving upward, so that the column rod 2211 can slide on the vertical section of the guide groove 223. At this time, the roller shaft 233 moves upward together and can rotate on the vertical edge of the support plate 234. The column rod 2211 can abut against the top block 224. As the column rod 2211 moves upward, the top block 224 can push the four column rods 2211 away from each other, which in turn can push the four movable frames 218 away from each other. At this time, the positioning seat 214 and the placement When seat 210 is closed, the welded basket ring can be fixed. The movement of movable frame 218 can drive moving rod 216 to slide on connecting block 215 and stretch support spring 217, so that a pushing force can be applied to the four placement seats 210 in opposite directions. When the four placement seats 210 move closer together, support spring 217 supports the placement seats 210, and connecting block 215 is less likely to slide on moving rod 216. At this time, since the basket ring is fixed by positioning seat 214 and placement seat 210, an outward pushing force can be applied to the four seamless steel pipes after welding and fixing. The reliability of the welding can be judged by observing whether there are cracks at the weld. Then, the movable plate 205 continues to move upward, and the column rod 2211 can pass through the top block 224. As the movable plate 205 continues to move upward, the roller shaft 233 can contact the inclined edge of the support plate 234. Under the action of the telescopic spring 231, the movable rod 226 moves, which can reset and rotate the positioning seat 214, so that the four positioning seats 214 can open simultaneously, thus facilitating the removal of the welded basket ring. During the welding process, the welding torch 102 can start the fan 307. Under the action of the fan 307, air can be drawn from the annular pipe 302 through the connecting pipe 305, so that the air inlet pipe 303 can be used to ventilate the welding process. The welding fumes are adsorbed. The fumes generated during welding can enter the annular pipe 302 through the inlet pipe 303, and then enter the housing 304 through the connecting pipe 305. The fumes can pass through the filter screen 310 to remove large particulate impurities, and then pass through the activated carbon screen 309. The activated carbon can adsorb harmful substances in the fumes. The front of the housing 304 is equipped with an inspection door, which is fixed to the housing 304 with screws. By removing the inspection door, it is easy to clean or replace the filter screen 310 and the activated carbon screen 309. Thus, the welding fumes generated during welding can be purified, improving practicality.
