Description

Technical Field

[0001] This utility model relates to the technical field of laser tube cutting machines, specifically to a follow-up support device for a laser tube cutting machine. Background Technology

[0002] Existing laser tube cutting machines require a follow-up support device during processing. This device clamps the workpiece and elevates it to a designated position. Then, through the extension and retraction of cylinders, it drives rollers on both sides to clamp the workpiece. During clamping, a centering mechanism is needed to synchronize the movement of the rollers on both sides, ensuring they simultaneously contact the workpiece and apply the same clamping force. Current centering mechanisms typically use gears and racks for driving. This type of drive structure requires high installation and machining precision, but also incurs high maintenance and replacement costs, making it unsuitable for long-term, high-volume production. Utility Model Content

[0003] This utility model proposes a follow-up support device for a laser tube cutting machine, which can realize the centering operation of the clamping rollers on both sides through driving pulleys and transmission ropes, ensuring that the clamping rollers on both sides can contact the workpiece simultaneously and apply the same clamping force. It has a simple structure, low installation accuracy, low replacement and maintenance costs, and is suitable for long-term production use.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A follower support device for a laser tube cutting machine includes a clamping mechanism. The clamping mechanism includes a vertically arranged support plate, on which two follower plates are horizontally slidably connected. Each follower plate has a vertically arranged clamping roller rotatably connected to its top. Pull lugs are also fixed on the follower plates. Drive pulleys are rotatably connected to both ends of the support plate in the horizontal direction. A transmission rope is wrapped around the two drive pulleys, and the pull lugs on the two follower plates are respectively fixedly connected to the transmission rope located on the upper and lower sides of the drive pulleys. When the two clamping rollers are in contact, the two pull lugs are located at the center of the two drive pulleys. A horizontally moving clamping cylinder is connected to one of the follower plates.

[0006] A further technical solution includes a lifting mechanism, which includes a lifting plate. A vertically moving lifting cylinder is fixed on the lifting plate. The top extension end of the lifting cylinder is hinged to a support plate. A vertically arranged guide rod can also be slidably connected to the lifting plate, and the top end of the guide rod is fixed to the support plate.

[0007] A further technical solution includes a lifting mechanism, which comprises a support plate vertically fixed to the laser tube cutting machine. The lifting plate and the support plate are slidably connected up and down. A lifting motor is fixed on the support plate. A synchronous wheel that rotates synchronously with the lifting motor is fixed at the output end of the lifting motor. The synchronous wheel is connected to a drive wheel via a belt drive. A vertically arranged threaded rod is rotatably connected to the support plate. One end of the threaded rod is coaxially fixed with the drive wheel. The lifting plate is sleeved on the threaded rod and threadedly matched with it.

[0008] A further technical solution is that a vertically arranged tensioning plate is fixed on the support plate, and one of the drive pulleys is rotatably connected to the tensioning plate. The tensioning plate has a horizontally arranged strip hole, and the support plate has a number of adjustment holes that match the position of the strip hole. The support plate and the tensioning plate are locked together by inserting bolts into the strip hole and the adjustment holes.

[0009] A further technical solution is that the top of the support plate is rotatably connected to a horizontally arranged transverse roller, which is located at the center of the two drive pulleys and at the bottom of the clamping roller.

[0010] A further technical solution is that the two follower plates are connected to the support plate through a guide sliding mechanism. The guide sliding mechanism includes two slide rails arranged vertically. Each follower plate is fixed with a slider that matches the slide rail and is slidably connected to one of the slide rails.

[0011] A further technical solution is that the lifting plate and the support plate can be slidably connected up and down through a guide mechanism two. The guide mechanism two includes two vertically arranged slide rails two, which are located on both sides of the support plate and connected to the lifting plate through matching sliders two.

[0012] A further technical solution is that protective covers are fixed to the outside of the clamping mechanism, the lifting mechanism and the jacking mechanism.

[0013] The working principle and beneficial effects of this application are as follows:

[0014] 1. The centering operation of the clamping rollers on both sides is achieved by using pulleys and transmission ropes, ensuring that the clamping rollers on both sides can contact the workpiece simultaneously and apply the same clamping force. The structure is simple, the installation accuracy is low, the replacement and maintenance costs are low, and it is suitable for long-term production use.

[0015] 2. The tension plate can adjust the tension of the transmission rope, increase the friction between the transmission rope and the drive pulley, prevent slippage, ensure effective power transmission, improve transmission efficiency, and extend the service life of the clamping mechanism.

[0016] 3. Through clamping, lifting and jacking mechanisms, the workpiece can be stably lifted and clamped, preventing the pipe workpiece from sagging or vibrating during the cutting process. It can adapt to pipe workpieces of different diameters, ensure cutting accuracy and improve processing efficiency. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-8 As shown, a follow-up support device for a laser tube cutting machine includes a clamping mechanism 1. The clamping mechanism 1 includes a vertically arranged support plate 11. Two follower plates 12 are horizontally slidably connected to the support plate 11. The top of each follower plate 12 is rotatably connected to a vertically arranged clamping roller 13. Pulling lugs 14 are also fixed on the follower plate 12. Drive pulleys 15 are rotatably connected to both ends of the support plate 11 in the horizontal direction. A transmission rope 16 is wrapped around the two drive pulleys 15. The pulling lugs 14 on the two follower plates 12 are respectively fixedly connected to the transmission rope 16 located on the upper and lower sides of the drive pulleys 15. When the two clamping rollers 13 are in contact, the two pulling lugs are located at the center of the two drive pulleys 15. A horizontally moving clamping cylinder 17 is connected to one of the follower plates 12.

[0029] In this embodiment, during use, the clamping cylinder 17 can drive one of the follower plates 12 to reciprocate in the horizontal direction. When the clamping cylinder 17 extends, the follower plate 12 moves along the support plate 11 to one end. The pull lug 14 on the follower plate 12 pulls the transmission rope 16 synchronously. At this time, the pull lug 14 on the other side of the drive pulley 15 will drive the other follower plate 12 fixed thereto to move synchronously to the other end of the support plate 11, thus realizing the synchronous separation of the two clamping rollers 13 fixed to the follower plate 12. Conversely, when the clamping cylinder 17 retracts, the two follower plates 12 move in opposite directions, that is, gradually approach each other, realizing the clamping of the pipe workpiece. When the two clamping rollers 13 are in contact, the two pull lugs are located at the center of the two drive pulleys 15, thus ensuring that the two clamping rollers 13 move synchronously and that the clamped workpiece is always kept in the center position.

[0030] like Figure 8As shown, a vertically arranged tension plate 18 is fixed on the support plate 11, and one of the drive pulleys 15 is rotatably connected to the tension plate 18. The tension plate 18 has a horizontally arranged strip-shaped hole 181, and the support plate 11 has several adjustment holes 10 that match the positions of the strip-shaped holes 181. The support plate 11 and the tension plate 18 are locked together by inserting bolts into the strip-shaped holes 181 and the adjustment holes 10. The tension of the transmission rope 16 can be adjusted by the tension plate 18, increasing the friction between the transmission rope 16 and the drive pulley 15, preventing slippage, ensuring effective power transmission, improving transmission efficiency, and extending the service life of the clamping mechanism 1. During adjustment, simply locking the strip hole 181 with the adjustment holes 10 at different positions can change the position of the two drive pulleys 15, thereby adjusting the tension of the transmission rope 16. Furthermore, after determining which adjustment hole 10 the strip hole 181 is fixed with, the strip hole 181 itself can also adjust the connection position to a certain extent, thereby adjusting the tension more precisely.

[0031] like Figure 6 As shown, this embodiment also includes a lifting mechanism 2, which includes a lifting plate 21. A vertically moving lifting cylinder 22 is fixed on the lifting plate 21. The top telescopic end of the lifting cylinder 22 is hinged to the support plate 11. A vertically arranged guide rod 23 can also be slidably connected to the lifting plate 21, and the top end of the guide rod 23 is fixed to the support plate 11. The lifting mechanism 2 controls the height of the support plate 11, i.e., the position after the workpiece is lifted and clamped, through the lifting cylinder 22, thereby dynamically adjusting according to different pipe workpieces to ensure that the cutting head is always in the optimal working position.

[0032] At the same time, such as Figure 5 and Figure 7 As shown, this embodiment also includes a lifting mechanism 3, which includes a support plate 31 vertically fixed to the laser tube cutting machine. A lifting plate 21 is slidably connected to the support plate 31. A lifting motor 32 is fixed on the support plate 31. A synchronous wheel 33, rotating synchronously with the lifting motor 32, is fixed to the output end of the lifting motor 32. A drive wheel 34 is connected to the synchronous wheel 33 via a belt drive. A vertically arranged threaded rod 35 is rotatably connected to the support plate 31. One end of the threaded rod 35 is coaxially fixed to the drive wheel 34. The lifting plate 21 is sleeved on the threaded rod 35 and threadedly connected to it. The lifting motor 32 drives the synchronous wheel 33 to rotate, which in turn drives the threaded rod 35 to rotate. The lifting plate 21, threadedly connected to the threaded rod 35, moves along the support plate 31. The lifting motor 32's forward and reverse rotation causes the lifting plate 21 to rise or fall.

[0033] Because the lifting plate 21 serves as the base plate of the lifting mechanism 2, the lifting mechanism 3 can ultimately achieve a wide range of height adjustment of the entire lifting mechanism 2. Compared with the dynamic adjustment of the lifting mechanism 2, which can flexibly track the surface fine-tuning position of the pipe workpiece, the function of the lifting mechanism 3 is to initially lift the workpiece and adjust its height over a wide range.

[0034] The clamping mechanism 1, lifting mechanism 2, and lifting mechanism 3 ensure stable lifting and clamping of the workpiece, preventing the pipe workpiece from sagging or vibrating during the cutting process. This adapts to pipe workpieces of different diameters, ensuring cutting accuracy and improving processing efficiency.

[0035] Matching it, such as Figure 3 As shown, a horizontally arranged transverse roller 4 is rotatably connected to the top of the support plate 11. The transverse roller 4 is located at the center of the two drive pulleys 15, and its height is located at the bottom of the clamping roller 13. The function of the transverse roller 4 is to lift and drive the pipe workpiece while maintaining the balance and stability of the pipe workpiece, preventing it from sagging or tilting.

[0036] The two follower plates 12 are connected to the support plate 11 via a sliding mechanism 5. The sliding mechanism 5 includes two vertically arranged slide rails 51. Each follower plate 12 is fixed with a slider 52 that matches the slide rail 51 and is slidably connected to one of the slide rails 51. The lifting plate 21 and the support plate 31 are slidably connected vertically via a sliding mechanism 6. The sliding mechanism 6 includes two vertically arranged slide rails 61. The two slide rails 61 are located on both sides of the support plate 31 and are connected to the lifting plate 21 via matching sliders 62.

[0037] Meanwhile, to enhance safety, protective covers 7 are fixed to the outside of the clamping mechanism 1, the lifting mechanism 2, and the jacking mechanism 3. The protective covers 7 can block cutting debris, prevent metal powder and other materials generated during the process from entering the transmission components, and also improve operational safety.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
