Description

Technical Field

[0001] This utility model relates to the field of chain production technology, specifically to a punching device for chain production. Background Technology

[0002] Chains are generally metal links or rings, primarily used for mechanical transmission and traction. They are chain-like objects used to obstruct traffic routes and chains used for mechanical transmission. Within the same product category, chains are classified according to their basic structure, namely, the shape of the components, the parts and locations that mesh with the chain, and the dimensional proportions between the parts. There are many types of chains, but their basic structures are only a few, with others being variations of these. Existing drilling devices used in automotive chain production cannot adjust the height of the drilling components during use, reducing worker efficiency. Furthermore, the waste generated during the drilling process using existing automotive chain production drilling devices cannot be easily recycled, easily leading to material waste.

[0003] To address these technical challenges, CN214867399U provides a punching device for automotive chain production. This device uses a bidirectional motor to drive a rotating rod, allowing the lifting rod to rise and fall, thus facilitating easy adjustment of the punching component's height and effectively improving chain punching efficiency. Furthermore, by designing the base as a groove, waste generated during chain punching can slide into the discharge hole, facilitating waste recycling and washing, and preventing material waste.

[0004] However, there may be some technical problems in its use. For example, when using the device, the electric telescopic rod needs to be started first to fix the chain, and then the height of the drilling drill needs to be adjusted by starting the motor. Then, the drilling drill is used to drill holes in the chain. However, this may make the operation of the device more complicated for the staff, and it is inconvenient for the staff to clamp and fix the chain before drilling. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a punching device for chain production that allows workers to easily clamp and fix chains before punching them.

[0006] This utility model is achieved through the following technical solution: a punching device for chain production is provided, including a base and two vertical plates disposed on the left and right sides of the top of the base. A support frame is installed between the two vertical plates, and a rotating rod is disposed within the support frame. The left and right ends of the rotating rod pass through the left and right vertical plates respectively. A motor is fixedly installed on the outer wall of one of the vertical plates. The left end of the rotating rod is coaxially fixed to the output shaft end of the motor. Two first sprockets are fixedly attached to the outer circumference of the rotating rod, respectively fitting against the outer walls of the two vertical plates. A horizontal bar is disposed on the inner wall of each of the two vertical plates. A threaded groove is formed on the outer wall of the horizontal bar, and a threaded rod is disposed within the threaded groove. The threads of the two threaded rods have opposite directions. A rotating rod is coaxially fixed to the outer wall of the threaded rod. Both rotating rods extend laterally in the left-right direction and pass through two vertical plates respectively. The rotating rods are rotatably connected to the vertical plates. A clamping plate is fixed to the inner wall of the horizontal rod. A limiting groove is also opened on the outer wall of the horizontal rod. A limiting rod fixed to the inner wall of the vertical plate is set in the limiting groove. A lifting mechanism is set on the support frame. A drilling drill fixed to the bottom of the lifting mechanism is set below the support frame. A gear fixed to the outer circumference of the rotating rod and meshing with the lifting gear in the lifting mechanism is set in the support frame. A magnetic sprocket is attached to the outer wall of the vertical plate and rotatably connected to the outer circumference of the rotating rod. The magnetic sprocket is connected to the first sprocket through chain drive.

[0007] In use, this utility model comprises a base and two vertical plates on the left and right sides of the top of the base. A support frame is installed between the two vertical plates, and a rotating rod is installed inside the support frame. The left and right ends of the rotating rod pass through the left and right vertical plates respectively. A motor is fixedly installed on the outer wall of one of the vertical plates. The left end of the rotating rod is coaxially fixed to the output shaft end of the motor. Two first sprockets, respectively, are fixed to the outer circumference of the rotating rod and fit against the outer walls of the two vertical plates. A horizontal bar is provided on the inner wall of each of the two vertical plates. A threaded groove is opened on the outer wall of the horizontal bar, and a threaded rod is installed in the threaded groove. A rotating rod is coaxially fixed to the outer wall of the threaded rod. Both rotating rods extend laterally in the left and right direction and pass through the two vertical plates respectively. A clamping plate is fixed to the inner wall of the horizontal bar, and a clamping plate is also opened on the outer wall of the horizontal bar. The device includes a limiting groove containing a limiting rod fixed to the inner wall of the vertical plate. A lifting mechanism is mounted on the support frame, and a drilling machine fixed to the bottom of the lifting mechanism is located below the support frame. A gear fixed to the outer circumference of the rotating rod and meshing with the lifting gear in the lifting mechanism is installed inside the support frame. A magnetic sprocket, rotatably connected to the outer circumference of the rotating rod, is fitted onto the outer wall of the vertical plate. The magnetic sprocket is connected to the first sprocket via a chain drive. In use, the chain to be drilled is placed between the two clamping plates, the drilling machine is started, and the motor is controlled to rotate its output shaft in the forward direction. This causes the rotating rod to rotate within the vertical plate and support frame, driving the gear to rotate within the support frame. This causes the lifting mechanism, which meshes with the gear, to move downwards, driving the drilling drill downwards as well. During this process, the rotating rod also drives the two first sprockets on the left and right to rotate, and causes the magnetic sprocket on the same side to rotate under the transmission of the chain. This causes the rotating rod to rotate within the vertical plate under the drive of the magnetic sprocket, thereby driving the threaded rod to rotate within the threaded groove of the horizontal bar. At this time, due to the limiting effect of the limiting groove and the limiting rod, the horizontal bar will not rotate with the threaded rod, but will move under the rotational drive of the threaded rod. Since the threads of the two threaded rods have opposite directions, the two horizontal bars will approach each other under the rotational drive of the two threaded rods and disengage from the inner wall of the vertical plate. This causes the two clamping plates to approach each other under the drive of the two horizontal bars and engage with the chain. The bars abut together, thus fixing the chain between the two clamping plates. After the chain is fixed, the rotating rod continues to rotate forward within the vertical plate and support frame under the drive of the motor output shaft. This causes the gear to continue rotating within the support frame, driven by the rotating rod. The lifting mechanism, meshing with the gear, continues to move downwards, driving the drilling drill downwards. This allows the drilling drill to contact the chain between the two clamping plates, thus drilling a hole in the clamped chain. During this process, the rotating rod also continues to drive the two first sprockets on the left and right to rotate, and the magnetic sprocket on the same side also continues to rotate under the transmission of the chain. At this time, because the two clamping plates clamp and fix the chain, the two clamping plates cannot approach each other, and the crossbar, threaded rod, and rotating rod remain relatively fixed.This allows the magnetic sprocket to overcome the attraction and fixation between itself and the rotating rod under the drive of the chain, and rotate on the rotating rod. After the drill finishes drilling the chain, the drill is turned off, and the motor output shaft is rotated in the opposite direction. This causes the rotating rod to rotate within the vertical plate and support frame, driven by the rotating rod. This causes the gear to rotate within the support frame, which in turn moves the lifting mechanism meshing with the gear upwards, moving the drill upwards as well. During this process, the rotating rod also drives the two first sprockets on the left and right to rotate, and the magnetic sprocket on the same side to rotate under the drive of the chain. This causes the rotating rod to rotate within the vertical plate under the drive of the magnetic sprocket, thus driving the threaded rod to rotate within the threaded groove of the horizontal bar. At this point, due to the limiting effect of the limiting groove and the limiting rod, the horizontal bar does not rotate with the threaded rod, but moves under the rotational drive of the threaded rod. Since the threads of the two threaded rods have opposite directions, the two horizontal bars will move under the rotational drive of the two threaded rods respectively. The clamping plates move away from each other and re-engage with the inner wall of the vertical plate. Driven by the two horizontal bars, the two clamping plates return to their initial positions, no longer abutting against the chain. This removes the chain from the clamping plates. After the chain disengages from the clamping plates, the rotating rod continues to rotate in the opposite direction within the vertical plate and support frame, driven by the motor output shaft. This causes the gear to continue rotating within the support frame, moving the lifting mechanism meshing with the gear upwards and driving the drilling drill upwards, returning it to its initial position. During this process, the rotating rod also continues to drive the two first sprockets on the left and right sides to rotate, and the magnetic sprocket on the same side also continues to rotate under the chain's transmission. Because the vertical plate and horizontal bars are still abutting, the two clamping plates cannot move away from each other further. The horizontal bars, threaded rod, and rotating rod remain relatively fixed, allowing the magnetic sprocket to overcome the attraction and fixation between itself and the rotating rod under the chain's drive, rotating on the rotating rod. This facilitates drilling after the chain is clamped and fixed.

[0008] Preferably, the lifting mechanism includes a through hole vertically extending from the top of the support frame. A vertical rod slidably connected to the inner wall of the through hole is disposed within the support frame. A lifting gear is mounted on the vertical rod. The drilling drill is fixedly connected to the bottom of the vertical rod, and the gear is located within the through hole. In use, the forward or reverse rotation of the gear, driven by the lifting gear meshing with it, causes the vertical rod to slide downwards or upwards along the inner wall of the through hole. This allows the drilling drill to move downwards or upwards with the vertical rod, thereby adjusting its height and facilitating drilling of the clamped chain.

[0009] Preferably, a rubber pad is fixed to the inner wall of the clamping plate. By fixing a rubber pad to the inner wall of the clamping plate, the clamping plate can be prevented from directly contacting the chain during use, thus avoiding scratches on the chain surface.

[0010] Preferably, the base has a groove in the middle, and a discharge hole is provided at the bottom center of the base. By making the base groove in the middle and providing a discharge hole at the bottom center of the base, a collection container can be placed below the discharge hole during use, allowing the waste generated during the drilling process to slide into the discharge hole and enter the container through the discharge hole, thereby recycling the waste.

[0011] Preferably, a limiting plate is provided above the support frame and fixedly connected to the top of the vertical rod. By providing a limiting plate above the support frame and fixedly connected to the top of the vertical rod, the stability of the vertical rod can be improved during use, preventing the vertical rod from coming out of the support frame during use.

[0012] Preferably, a mounting plate is fixedly connected to the outer wall of one of the vertical plates, and the motor is fixedly mounted on the outer wall of one of the vertical plates via the mounting plate. By fixing the mounting plate to the outer wall of one of the vertical plates and fixing the motor on the outer wall of one of the vertical plates via the mounting plate, the stability between the motor and one of the vertical plates can be improved during use.

[0013] The beneficial effects of this utility model are as follows: A base is provided, and two vertical plates are set on the left and right sides of the top of the base. A support frame is installed between the two vertical plates, and a rotating rod is installed inside the support frame. The left and right ends of the rotating rod pass through the left and right vertical plates respectively. A motor is fixedly installed on the outer wall of one of the vertical plates. The left end of the rotating rod is coaxially fixed to the output shaft end of the motor. Two first sprockets, respectively fitting against the outer walls of the two vertical plates, are fixedly attached to the outer circumference of the rotating rod. A horizontal bar is provided on the inner wall of each of the two vertical plates. A threaded groove is opened on the outer wall of the horizontal bar, and a threaded rod is installed in the threaded groove. A rotating rod is coaxially fixed to the outer wall of the threaded rod. Both rotating rods extend laterally in the left-right direction and pass through the two vertical plates respectively. A clamping plate is fixedly attached to the inner wall of the horizontal bar, and a clamping plate is also opened on the outer wall of the horizontal bar. The device includes a limiting groove containing a limiting rod fixed to the inner wall of the vertical plate. A lifting mechanism is mounted on the support frame, and a drilling machine fixed to the bottom of the lifting mechanism is located below the support frame. A gear fixed to the outer circumference of the rotating rod and meshing with the lifting gear in the lifting mechanism is installed inside the support frame. A magnetic sprocket, rotatably connected to the outer circumference of the rotating rod, is fitted onto the outer wall of the vertical plate. The magnetic sprocket is connected to the first sprocket via a chain drive. In use, the chain to be drilled is placed between the two clamping plates, the drilling machine is started, and the motor is controlled to rotate its output shaft in the forward direction. This causes the rotating rod to rotate within the vertical plate and support frame, driving the gear to rotate within the support frame. This causes the lifting mechanism, which meshes with the gear, to move downwards, driving the drilling drill downwards as well. During this process, the rotating rod also drives the two first sprockets on the left and right to rotate, and causes the magnetic sprocket on the same side to rotate under the transmission of the chain. This causes the rotating rod to rotate within the vertical plate under the drive of the magnetic sprocket, thereby driving the threaded rod to rotate within the threaded groove of the horizontal bar. At this time, due to the limiting effect of the limiting groove and the limiting rod, the horizontal bar will not rotate with the threaded rod, but will move under the rotational drive of the threaded rod. Since the threads of the two threaded rods have opposite directions, the two horizontal bars will approach each other under the rotational drive of the two threaded rods and disengage from the inner wall of the vertical plate. This causes the two clamping plates to approach each other under the drive of the two horizontal bars and engage with the chain. The bars abut together, thus fixing the chain between the two clamping plates. After the chain is fixed, the rotating rod continues to rotate forward within the vertical plate and support frame under the drive of the motor output shaft. This causes the gear to continue rotating within the support frame, driven by the rotating rod. The lifting mechanism, meshing with the gear, continues to move downwards, driving the drilling drill downwards. This allows the drilling drill to contact the chain between the two clamping plates, thus drilling a hole in the clamped chain. During this process, the rotating rod also continues to drive the two first sprockets on the left and right to rotate, and the magnetic sprocket on the same side also continues to rotate under the transmission of the chain. At this time, because the two clamping plates clamp and fix the chain, the two clamping plates cannot approach each other, and the crossbar, threaded rod, and rotating rod remain relatively fixed.This allows the magnetic sprocket to overcome the attraction and fixation between itself and the rotating rod under the drive of the chain, and rotate on the rotating rod. After the drill finishes drilling the chain, the drill is turned off, and the motor output shaft is rotated in the opposite direction. This causes the rotating rod to rotate within the vertical plate and support frame, driven by the rotating rod. This causes the gear to rotate within the support frame, which in turn moves the lifting mechanism meshing with the gear upwards, moving the drill upwards as well. During this process, the rotating rod also drives the two first sprockets on the left and right to rotate, and the magnetic sprocket on the same side to rotate under the drive of the chain. This causes the rotating rod to rotate within the vertical plate under the drive of the magnetic sprocket, thus driving the threaded rod to rotate within the threaded groove of the horizontal bar. At this point, due to the limiting effect of the limiting groove and the limiting rod, the horizontal bar does not rotate with the threaded rod, but moves under the rotational drive of the threaded rod. Since the threads of the two threaded rods have opposite directions, the two horizontal bars will move under the rotational drive of the two threaded rods respectively. The clamping plates move away from each other and re-engage with the inner wall of the vertical plate. Driven by the two horizontal bars, the two clamping plates return to their initial positions, no longer abutting against the chain. This removes the chain from the clamping plates. After the chain disengages from the clamping plates, the rotating rod continues to rotate in the opposite direction within the vertical plate and support frame, driven by the motor output shaft. This causes the gear to continue rotating within the support frame, moving the lifting mechanism meshing with the gear upwards and driving the drilling drill upwards, returning it to its initial position. During this process, the rotating rod also continues to drive the two first sprockets on the left and right sides to rotate, and the magnetic sprocket on the same side also continues to rotate under the chain's transmission. Because the vertical plate and horizontal bars are still abutting, the two clamping plates cannot move away from each other further. The horizontal bars, threaded rod, and rotating rod remain relatively fixed, allowing the magnetic sprocket to overcome the attraction and fixation between itself and the rotating rod under the chain's drive, rotating on the rotating rod. This facilitates drilling after the chain is clamped and fixed. Attached Figure Description

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figures 1-5 The present invention discloses a punching device for chain production, comprising a base 3 and two vertical plates 12 disposed on the left and right sides of the top of the base 3. A support frame 6 is installed between the two vertical plates 12, and a rotating rod 5 is disposed within the support frame 6. The left and right ends of the rotating rod 5 pass through the left and right vertical plates 12 respectively. A motor 1 is fixedly installed on the outer wall of one of the vertical plates 12. The left end of the rotating rod 5 is coaxially fixed to the output shaft end of the motor 1. Two first sprockets 15 are fixedly attached to the outer circumference of the rotating rod 5, respectively fitting against the outer walls of the two vertical plates 12. A crossbar 11 is disposed on the inner wall of each of the two vertical plates 12. A threaded groove 18 is formed on the outer wall of the crossbar 11, and a threaded rod 19 is disposed within the threaded groove 18. The threads of the two threaded rods 19 have opposite directions, and the threads on the outer walls of the threaded rods 19 are aligned with the outer wall of the crossbar 19. A rotating rod 17 is fixedly connected to the shaft. Both rotating rods 17 extend laterally in the left-right direction and pass through the two vertical plates 12 respectively. The rotating rods 17 are rotatably connected to the vertical plates 12. A clamping plate 13 is fixedly connected to the inner side wall of the horizontal rod 11. A limiting groove 22 is also opened on the outer side wall of the horizontal rod 11. A limiting rod 21 fixedly connected to the inner side wall of the vertical plate 12 is provided in the limiting groove 22. A lifting mechanism is provided on the support frame 6. A drilling drill 7 fixedly connected to the bottom of the lifting mechanism is provided below the support frame 6. A gear 24 fixedly connected to the outer peripheral surface of the rotating rod 5 and meshing with the lifting gear 8 in the lifting mechanism is provided in the support frame 6. A magnetic sprocket 16 rotatably connected to the outer peripheral surface of the rotating rod 17 is attached to the outer side wall of the vertical plate 12. The magnetic sprocket 16 is connected to the first sprocket 15 through a chain 2.

[0017] The lifting mechanism includes a through hole 23 vertically extending through the top of the support frame 6. A vertical rod 10, slidably connected to the inner wall of the through hole 23, is installed inside the support frame 6. A lifting gear 8 is mounted on the vertical rod 10. A drilling drill 7 is fixedly connected to the bottom of the vertical rod 10. A gear 24 is located inside the through hole 23. During use, the forward or reverse rotation of the gear 24, driven by the lifting gear 8 meshing with it, causes the vertical rod 10 to slide downwards or upwards on the inner wall of the through hole 23. This allows the drilling drill 7 to move downwards or upwards with the vertical plate 12, thereby adjusting the height of the drilling drill 7 and facilitating drilling of the clamped chain 2. A rubber pad 14 is fixed to the inner wall of the clamping plate 13 to prevent direct contact between the clamping plate 13 and the chain 2 during use, thus avoiding scratches on the chain 2 surface. By making the base 3 recessed in the middle and providing a discharge hole 20 at the bottom center, a collection container is placed below the discharge hole 20 during use. This allows waste debris generated during drilling to slide into the discharge hole 20 and enter the container for recycling. A limiting plate 9, fixed to the top of the vertical rod 10, is provided above the support frame 6. This limiting plate 9 improves the stability of the vertical rod 10 during use, preventing it from detaching from the support frame 6. A mounting plate 4 is fixed to the outer wall of one of the vertical plates 12, and the motor 1 is fixedly mounted on the outer wall of one of the vertical plates 12 via the mounting plate 4. This mounting plate 4 improves the stability between the motor 1 and one of the vertical plates 12 during use.

[0018] Combined with appendix Figure 1-5The method of using this utility model is as follows: First, the chain 2 to be drilled is placed between the two clamping plates 13. The drilling drill 7 is turned on. Then, the motor 1 on the mounting plate 4 is controlled to make the output shaft of the motor 1 rotate in the forward direction. The rotating rod 5 rotates with the rotation of the output shaft of the motor 1 within the vertical plate 12 and the support frame 6. This causes the gear 24 to rotate within the support frame 6 under the drive of the rotating rod 5. This causes the vertical rod 10 to slide downward on the inner wall of the through hole 23 under the transmission of the lifting gear 8 meshing with the gear 24. The drilling drill 7 also moves downward with the vertical plate 12. During this process, the rotating rod 5 also drives the two first sprockets 15 on the left and right to rotate, and the magnetic sprocket 16 on the same side also rotates under the transmission of the chain 2. The magnetic sprocket 16 drives the rotating rod 17 to rotate within the vertical plate 12, thereby causing the threaded rod 19 to rotate within the threaded groove 18 of the horizontal rod 11. Due to the limiting effect of the limiting groove 22 and the limiting rod 21, the horizontal rod 11 does not rotate with the threaded rod 19, but moves under the rotational drive of the threaded rod 19. Since the threads of the two threaded rods 19 have opposite directions, the two horizontal rods 11 will approach each other under the rotational drive of the two threaded rods 19 and disengage from the inner wall of the vertical plate 12. This causes the rubber pads 14 on the two clamping plates 13 to approach each other under the drive of the two horizontal rods 11 and abut against the chain 2, thereby fixing the chain 2 between the two clamping plates 13. The chain 2 is then... After fixing, the rotating rod 5 continues to rotate forward within the vertical plate 12 and support frame 6 under the drive of the output shaft of motor 1. This causes gear 24 to continue rotating within the support frame 6 under the drive of the rotating rod 5, causing the lifting mechanism meshing with gear 24 to continue moving downwards. This moves the drilling drill 7 downwards, allowing it to contact the chain 2 between the two clamping plates 13, thus drilling a hole in the clamped chain 2. During this process, the rotating rod 5 will also continue to drive the two first sprockets 15 on the left and right to rotate, and the magnetic sprocket 16 on the same side will also continue to rotate under the transmission of the chain 2. At this time, because the two clamping plates 13 clamp and fix the chain 2, the two clamping plates 13 cannot approach each other, and the horizontal rod 11, threaded rod 19, and rotating rod 17 will remain in contact. The magnetic sprocket 16 is relatively fixed, thus overcoming the attraction and fixation between itself and the rotating rod 17 under the drive of the chain 2, and rotates on the rotating rod 17. After the drilling drill 7 finishes drilling the chain 2, the drilling drill 7 is turned off. Then, by controlling the motor 1 on the mounting plate 4, the output shaft of the motor 1 is rotated in the opposite direction, causing the rotating rod 5 to rotate within the vertical plate 12 and the support frame 6 along with the rotation of the output shaft of the motor 1. This causes the gear 24 to rotate within the support frame 6 under the drive of the rotating rod 5, thereby causing the vertical rod 10 to slide upward on the inner wall of the through hole 23 under the transmission of the lifting gear 8 meshing with the gear 24. This causes the drilling drill 7 to move upward along with the vertical plate 12. During this process, the rotating rod 5 also drives the two left and right first sprockets 15 to rotate.The magnetic sprocket 16 on the same side also rotates under the drive of the chain 2, causing the rotating rod 17 to rotate within the vertical plate 12 under the drive of the magnetic sprocket 16. This drives the threaded rod 19 to rotate within the threaded groove 18 of the horizontal rod 11. At this time, due to the limiting effect of the limiting groove 22 and the limiting rod 21, the horizontal rod 11 will not rotate with the threaded rod 19, but will move under the rotation drive of the threaded rod 19. Since the threads of the two threaded rods 19 have opposite directions of rotation... Therefore, the two horizontal bars 11 will move away from each other under the rotational drive of the two threaded rods 19, and re-abut against the inner wall of the vertical plate 12. This causes the rubber pads 14 on the two clamping plates 13 to move away from each other and return to their initial positions under the drive of the two horizontal bars 11, no longer abutting against the chain 2. Thus, the chain 2 between the two clamping plates 13 is no longer fixed. After the chain 2 is disengaged from the clamping plates 13, the rotating rod 5 continues to move in the opposite direction between the vertical plate 12 and the support frame 6 under the drive of the output shaft of the motor 1. The rotation causes gear 24 to continue rotating within the support frame 6 under the drive of the rotating rod 5. This causes the vertical rod 10 to continue sliding upward on the inner wall of the through hole 23 under the transmission of the lifting gear 8 meshing with gear 24, and driving the drilling drill 7 to move upward, thus returning the drilling drill 7 to its initial position. During this process, the rotating rod 5 will also continue to drive the two first sprockets 15 on the left and right to rotate, and the magnetic sprocket 16 on the same side will also continue to rotate under the transmission of the chain 2. At this time, because the vertical plate 12 and the horizontal rod 11 are in contact, the two clamping plates 13 cannot continue to move away from each other. The horizontal rod 11, the threaded rod 19 and the rotating rod 17 will remain relatively fixed, so that the magnetic sprocket 16, driven by the chain 2, overcomes the adsorption and fixing effect between itself and the rotating rod 17 and rotates on the rotating rod 17. A collection container is placed below the discharge hole 20, which allows the waste generated during the drilling process to slide into the discharge hole 20 and enter the container through the discharge hole 20, thereby recycling the waste. ,
