Description

Technical Field

[0001] This application relates to the technical field of pipe processing, and in particular to a stainless steel pipe cutting and positioning device. Background Technology

[0002] Stainless steel pipes are widely used in new energy, precision manufacturing, automotive, and medical device industries, especially in applications such as power battery casings and microreactor tubing, where high precision and consistency in cutting dimensions are required. With the development of industrial automation, pipe cutting processes are gradually moving towards semi-automation or automation. The following two mainstream measurement and cutting positioning technologies are widely used in the market:

[0003] Mechanical limit cutting device: Some small and medium-sized enterprises still use mechanical slide rail limit structure, which determines the cutting length by setting limit blocks. Although it has a certain degree of repeatability, it is difficult to adjust flexibly according to the actual pipe length, and it does not have the ability to measure and correct, resulting in the accumulation of dimensional errors.

[0004] Laser length measurement combined with servo control automatic cutting system: In some highly automated production lines, laser length measuring instruments, photoelectric encoders, or vision systems are combined with CNC cutting equipment to perform online length measurement and positioning control of pipes. Although this type of system has high measurement accuracy and can achieve closed-loop control, it is usually complex, costly, and has a high system debugging threshold, making it unsuitable for small and medium-sized processing enterprises or mobile operation scenarios.

[0005] Furthermore, both mechanical limit devices and laser automatic length measurement systems generally suffer from problems such as cumbersome adjustments, poor equipment compatibility, or lack of rapid positioning functions when facing cutting tasks with different length specifications or non-standard sizes. Therefore, in many customized processing or multi-variety, small-batch scenarios, some companies still use manual measurement and marking positioning as auxiliary means, especially when flexible automated equipment is lacking. Although this method is simple to operate, it suffers from problems such as unstable measurement accuracy, large human error, poor repeatability, and low cutting efficiency, making it difficult to meet the requirements of high-precision, high-frequency cutting.

[0006] In summary, while current technologies for stainless steel pipe cutting and positioning have achieved a certain degree of automation, they still have the following limitations:

[0007] Positioning accuracy is limited;

[0008] The equipment suffers from low versatility and low adjustment efficiency.

[0009] It is difficult to strike a balance between accuracy, efficiency, and cost.

[0010] Therefore, there is an urgent need for a stainless steel pipe cutting and positioning device that is simple in structure, accurate in positioning, highly adaptable and cost-effective, in order to meet the comprehensive requirements of efficiency and accuracy of the entire process of measurement, positioning and cutting in different application scenarios. Summary of the Invention

[0011] To improve the cutting efficiency of stainless steel pipes, this application provides a stainless steel pipe cutting positioning device.

[0012] This application provides a stainless steel pipe cutting and positioning device, which adopts the following technical solution:

[0013] A stainless steel pipe cutting and positioning device includes a base, on which a positioning mechanism is provided for determining the cutting position of the stainless steel pipe. A first three-jaw chuck is fixedly installed on the positioning mechanism. A clamping mechanism is provided on the end of the base away from the positioning mechanism. The first three-jaw chuck and the clamping mechanism are used to fix the stainless steel pipe. A cutting device is provided on the base and is located between the clamping mechanism and the positioning mechanism.

[0014] The positioning mechanism includes:

[0015] A slide rail is fixedly mounted on the base and is arranged along the length of the base;

[0016] A slider is slidably mounted inside the slide rail and slides along the length of the slide rail;

[0017] A mobile platform, which is fixedly connected to the slider;

[0018] A mobile component, connected to the mobile platform, wherein the mobile component is used to control the displacement of the mobile platform;

[0019] A fastening assembly, which is connected to the mobile platform and is used to lock the mobile platform;

[0020] A measuring component is connected to the first three-jaw chuck, and the measuring component is used to measure the length of the cut pipe.

[0021] By employing the above technical solution, the moving component causes the moving platform to shift, thus moving the stainless steel pipe. When the measuring mechanism determines that the stainless steel pipe has moved to the required length, the fastening component locks the position of the moving platform. Next, the clamping mechanism clamps the other end of the stainless steel pipe, and then the cutting device is activated to cut the stainless steel pipe. Combining the measuring and moving components replaces the traditional method of using a measuring tape to locate the cutting point of the stainless steel pipe, significantly improving measurement accuracy and speed, thereby increasing the cutting efficiency of the stainless steel pipe.

[0022] Optionally, the moving component includes:

[0023] A lead screw is rotatably mounted on the base, and the length direction of the lead screw is set along the sliding direction of the moving platform. The lead screw is connected to the clamping mechanism.

[0024] A lead screw nut is threadedly connected to the lead screw and fixedly connected to the moving platform.

[0025] By adopting the above technical solution, the movement distance of the stainless steel pipe is controlled by the lead screw and lead screw nut, which helps to improve measurement accuracy and further improve cutting efficiency.

[0026] Optionally, the fastening assembly includes:

[0027] A pressure plate, which is slidably mounted on the slider, slides along the vertical direction;

[0028] A diaphragm spring, one end of which is fixedly connected to the end of the pressure plate near the slide rail, and the other end of which can enter the slide rail and abut against the bottom of the slide rail;

[0029] A hydraulic cylinder is fixedly mounted on one end of the mobile platform near the base.

[0030] A wedge block is fixedly installed on the movable end of the hydraulic cylinder. One end of the wedge block abuts against the moving platform, and the other end of the wedge block abuts against the pressure plate.

[0031] By adopting the above technical solution, the combination of hydraulic cylinder, wedge block, pressure plate and diaphragm spring can quickly fix the moving platform, which is beneficial to improving cutting efficiency.

[0032] Optionally, the clamping mechanism includes:

[0033] The second three-jaw chuck is fixedly installed on the end of the base away from the moving platform, and the fixing point of the second three-jaw chuck is located on the end face;

[0034] Three rotating shafts, one end of each of the three rotating shafts being detachably connected to the square hole of the second three-jaw chuck;

[0035] Three first bevel gears are respectively coaxially and fixedly connected to the ends of the three rotating shafts away from the second three-jaw chuck.

[0036] Three second bevel gears, each corresponding to and meshing with one of the three first bevel gears, and all three second bevel gears are rotatably mounted on the second three-jaw chuck;

[0037] The rotating ring has bevel teeth at both ends of its inner diameter. One end of the bevel teeth meshes with three second bevel gears. The rotating ring is coaxially arranged with the second three-jaw chuck.

[0038] The third bevel gear meshes with the end of the rotating ring away from the second bevel gear, and the third bevel gear is rotatably mounted on the base;

[0039] A transmission assembly, which is connected to the third bevel gear and the lead screw.

[0040] Through the above technical solution, when the lead screw rotates, its torque is sequentially transmitted to the third bevel gear through a set transmission component. The third bevel gear meshes with a rotating ring located on its side, thereby driving the rotating ring to rotate synchronously. The rotation of the rotating ring further drives the second bevel gear meshing with it to rotate; the second bevel gear meshes with the first bevel gear at an angle, and the first bevel gear rotates accordingly, driving the rotating shaft coaxially connected with it to rotate.

[0041] The rotation of the shaft drives the second and third jaw chucks through a linkage structure, achieving automatic clamping or release of the stainless steel pipe. Because this transmission process is synchronized with the stroke control of the lead screw moving platform, the clamping operation of the stainless steel pipe can be automatically completed during the positioning or movement of the moving platform. This avoids manual intervention, improves clamping efficiency and the overall continuity of the cutting process, thereby effectively enhancing the processing efficiency and dimensional consistency of pipe cutting.

[0042] Optionally, the transmission assembly includes:

[0043] The first gear is coaxially and fixedly connected to the third bevel gear;

[0044] The second gear meshes with the first gear and the second gear, and the second gear is rotatably mounted on the base. The second gear is coaxially arranged with the lead screw.

[0045] A separator is coaxially connected to the second gear and to the lead screw. The separator is used to separate the torque transmission between the lead screw and the second gear.

[0046] By adopting the above technical solution, when the second and third jaw chuck clamps the stainless steel pipe but the pipe length is not yet the required length, the separating component allows the lead screw to continue rotating, while the second gear rotates in the opposite direction, releasing the stainless steel pipe and allowing it to move. After cutting, during the resetting process of the moving platform, the lead screw rotation causes the second and third jaw chuck to release the stainless steel pipe, shortening the time for adjusting the device during the next cut and improving cutting efficiency.

[0047] Optionally, the separator includes:

[0048] The first magnetic wheel is coaxially and fixedly connected to the lead screw;

[0049] The second magnetic wheel is coaxially and fixedly connected to the second gear, and the rotation of the second magnetic wheel can drive the first magnetic wheel to rotate;

[0050] An isolation plate is slidably mounted on the base, located between the first magnetic wheel and the second magnetic wheel, and the sliding direction of the isolation plate is along the horizontal diameter direction of the first magnetic wheel.

[0051] By adopting the above technical solution, when the moving platform is locked and the stainless steel pipe is clamped, the isolation plate is moved to a position away from the first magnetic wheel. At this time, the moving platform is locked, the first magnetic wheel cannot rotate, and the second magnetic wheel is also difficult to rotate, ensuring that the stainless steel pipe can be clamped, which helps to improve cutting efficiency.

[0052] Optionally, the measurement component includes:

[0053] A positioning plate is fixedly connected to the end of the first three-jaw chuck away from the second three-jaw chuck.

[0054] The reading line is located on the side wall of the moving platform, and the reading line and the end of the positioning plate near the first three-jaw chuck are on the same plane.

[0055] The scale lines are formed on the side wall of the base. The reading line is located on the same side as the scale lines. The origin of the scale lines is on the same plane as the end of the cutting device near the moving platform.

[0056] By adopting the above technical solution, one end of the stainless steel pipe abuts against the positioning plate, and then the stainless steel pipe is clamped using a first three-jaw chuck. Next, the moving platform moves away from the clamping mechanism. When the reading line reaches the position on the scale line where the required cutting length is desired, the moving platform is locked. At this point, the cutting device cuts the stainless steel pipe, achieving synchronization of measurement and cutting, which helps improve cutting efficiency.

[0057] In summary, this application includes at least one of the following beneficial technical effects:

[0058] By combining the measuring and moving components, the traditional method of using a measuring tape to locate the cutting point of stainless steel pipes is replaced, which significantly improves the measurement accuracy and measurement speed, thereby improving the cutting efficiency of stainless steel pipes.

[0059] When the moving platform is locked and the stainless steel pipe is clamped, move the isolation plate away from the first magnetic wheel. At this time, the moving platform is locked, the first magnetic wheel cannot rotate, and the second magnetic wheel is also difficult to rotate, ensuring that the stainless steel pipe can be clamped, which helps to improve cutting efficiency.

[0060] One end of the stainless steel pipe abuts against the positioning plate, and then the stainless steel pipe is clamped using the first three-jaw chuck. Next, the moving platform moves away from the clamping mechanism. When the reading line reaches the position on the scale where the required cutting length is desired, the moving platform is locked. At this point, the cutting device cuts the stainless steel pipe, achieving synchronization of measurement and cutting, which helps improve cutting efficiency. Attached Figure Description

[0074] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0075] This application discloses a stainless steel pipe cutting and positioning device.

[0076] Reference Figure 1 The stainless steel pipe cutting and positioning device includes a base 1, on which a positioning mechanism is provided. The positioning mechanism is used to determine the cutting position of the stainless steel pipe. A first three-jaw chuck 2 is fixedly installed on the positioning mechanism. A clamping mechanism is provided on the end of the base 1 away from the positioning mechanism. The first three-jaw chuck 2 and the clamping mechanism together fix the stainless steel pipe. A cutting device 3 is provided on the base 1, and the cutting device 3 is located between the clamping mechanism and the positioning mechanism.

[0077] Reference Figure 2 and Figure 3 The positioning mechanism includes two slide rails 41, which are parallel and fixedly mounted on the base 1. The slide rails 41 are arranged along the length of the base 1. Slider 42 is slidably mounted inside the two slide rails 41, and the sliding direction of the slider 42 is along the length of the slide rail 41. The two sliders 42 are fixedly connected to a moving platform 43. The moving platform 43 is connected to a moving component 44, which is used to control the displacement of the moving platform 43. The moving platform 43 is also connected to a fastening component, which is used to lock the moving platform 43. The first three-jaw chuck 2 is connected to a measuring component 46, which is used to measure the length of the cut pipe.

[0078] In use, one end of the stainless steel pipe to be cut is clamped by the first three-jaw chuck 2 and abuts against the measuring mechanism. Then, the moving component 44 causes the moving platform 43 to shift, moving the stainless steel pipe. When the measuring mechanism measures that the stainless steel pipe has moved to the required length, the fastening component locks the position of the moving platform 43. Next, the clamping mechanism clamps the other end of the stainless steel pipe, and then the cutting device 3 starts cutting the stainless steel pipe. By combining the measuring component 46 and the moving component 44, the traditional method of using a measuring tape to locate the cutting point of the stainless steel pipe is replaced, significantly improving measurement accuracy and speed, thereby increasing the cutting efficiency of the stainless steel pipe.

[0079] Reference Figure 2 The moving component 44 includes a lead screw 441, which is rotatably mounted on the base 1. The length direction of the lead screw 441 is set along the sliding direction of the moving platform 43. The lead screw 441 is connected to the clamping mechanism. A lead screw nut 442 is threaded onto the lead screw 441 and is fixedly connected to the moving platform 43.

[0080] In use, when the moving platform 43 needs to be moved, the lead screw 441 is rotated, and the lead screw nut 442 moves along the length of the lead screw 441, thus moving the moving platform 43 and the stainless steel pipe. Controlling the movement distance of the stainless steel pipe through the lead screw 441 and lead screw nut 442 improves measurement accuracy and further enhances cutting efficiency.

[0081] Reference Figure 3 , Figure 4 and Figure 5 The fastening assembly includes a pressure plate 451, which is slidably mounted on the slider 42 and slides vertically. One end of a diaphragm spring 452 is fixedly connected to one end of the pressure plate 451 near the slide rail 41, and the other end of the diaphragm spring 452 can enter the slide rail 41 and abut against the bottom of the slide rail 41. A hydraulic cylinder 453 is fixedly mounted on one end of the moving platform 43 near the base 1. A wedge 454 is fixedly mounted on the movable end of the hydraulic cylinder 453, and one end of the larger end of the wedge 454 abuts against the moving platform 43, while the other end of the larger end of the wedge 454 abuts against the pressure plate 451.

[0082] In use, once the moving platform 43 is moved to the desired position, the operator activates the hydraulic cylinder 453. The movable end of the cylinder 453 pushes the wedge block 454 to move. The movement of the wedge block 454 causes the pressure plate 451 to move closer to the slide rail 41. The diaphragm spring 452 is compressed and comes into contact with the bottom of the slide rail 41, thus fixing the moving platform 43 in place. The rapid fixing of the moving platform 43 through the cooperation of the hydraulic cylinder 453, wedge block 454, pressure plate 451, and diaphragm spring 452 improves cutting efficiency.

[0083] Reference Figure 6 The clamping mechanism includes a second three-jaw chuck 51, which is fixedly mounted on the end of the base 1 away from the moving platform 43, with the fixing point of the second three-jaw chuck 51 located on its end face. Each of the three square holes of the second three-jaw chuck 51 can be detachably connected to one end of a rotating shaft 52. A first bevel gear 53 is coaxially fixedly mounted on the other end of each of the three rotating shafts 52. Each of the three first bevel gears 53 meshes with a second bevel gear 54, and the three second bevel gears 54 are rotatably mounted on the second three-jaw chuck 51. The clamping mechanism also includes a rotating ring 55, with bevel teeth at both ends of its inner diameter. One end of the rotating ring 55's bevel teeth meshes with all three second bevel gears 54, and the rotating ring 55 is coaxially arranged with the second three-jaw chuck 51. A third bevel gear 56 meshes with the end of the rotating ring 55 away from the second bevel gear 54, and the third bevel gear 56 is rotatably mounted on the base 1. The third bevel gear 56 is connected to a transmission assembly, which is connected to a lead screw 441.

[0084] In operation, rotating the lead screw 441 transmits its torque sequentially to the third bevel gear 56 via a pre-set transmission assembly. The third bevel gear 56 meshes with a rotating ring 55 located on its side, causing the rotating ring 55 to rotate synchronously. The rotation of the rotating ring 55 further drives the second bevel gear 54, which meshes with it, to rotate. The second bevel gear 54 meshes with the first bevel gear 53 at an angle, causing the first bevel gear 53 to rotate and drive the rotating shaft 52, which is coaxially connected to it, to rotate. The rotation of the rotating shaft 52 drives the second three-jaw chuck 51 through a linkage structure, achieving automatic clamping or release of the stainless steel pipe. This avoids manual intervention, improves clamping efficiency and the overall continuity of the cutting process, thereby effectively improving the processing efficiency and dimensional consistency of pipe cutting.

[0085] Reference Figure 7 The transmission assembly includes a first gear 571, which is coaxially and fixedly connected to a third bevel gear 56; the first gear 571 meshes with a second gear 572, which is rotatably mounted on the base 1 and coaxially arranged with a lead screw 441; the transmission assembly also includes a separator 573, which is coaxially connected to the second gear 572 and connected to the lead screw 441. The separator 573 is used to separate the torque transmission between the lead screw 441 and the second gear 572.

[0086] In operation, rotating the lead screw 441 causes the moving platform 43 to move. Simultaneously, the separating element 573 transmits the torque of the lead screw 441 to the second gear 572. The rotation of the second gear 572 causes the first gear 571 to rotate, and the torque of the first gear 571 is transmitted to the third bevel gear 56. Under the combined action of the rotating ring 55, the second bevel gear 54, the first bevel gear 53, and the rotating shaft 52, the stainless steel pipe is clamped by the second three-jaw chuck 51. When the second three-jaw chuck 51 clamps the stainless steel pipe but the pipe length is not yet the required length, the separating element 573 allows the lead screw 441 to continue rotating, while the second gear 572 rotates in the opposite direction, releasing the stainless steel pipe and allowing it to displace. After cutting, during the resetting process of the moving platform 43, the rotation of the lead screw 441 releases the stainless steel pipe from the second three-jaw chuck 51, shortening the time required for adjusting the device before the next cut and improving cutting efficiency.

[0087] Reference Figure 7 The separating component 573 includes a first magnetic wheel 5731 and a second magnetic wheel 5732. The first magnetic wheel 5731 is coaxially and fixedly connected to the lead screw 441, and the second magnetic wheel 5732 is coaxially and fixedly connected to the second gear 572. The first magnetic wheel 5731 can drive the second magnetic wheel 5732 to rotate. An isolation plate 5733 is slidably installed on the base 1. The isolation plate 5733 is located between the first magnetic wheel 5731 and the second magnetic wheel 5732. The sliding direction of the isolation plate 5733 is along the horizontal diameter direction of the first magnetic wheel 5731.

[0088] When the first magnetic wheel 5731 and the second magnetic wheel 5732 need to rotate together to transmit torque, the isolation plate 5733 is slid to the end away from the first magnetic wheel 5731. When the first magnetic wheel 5731 and the second magnetic wheel 5732 need to rotate independently, the isolation plate 5733 is slid between the first magnetic wheel 5731 and the second magnetic wheel 5732, thus isolating the magnetic field lines between them and preventing interference. When the moving platform 43 is locked and the stainless steel pipe is clamped, the isolation plate 5733 is moved to a position away from the first magnetic wheel 5731. At this time, the moving platform 43 is locked, the first magnetic wheel 5731 cannot rotate, and the second magnetic wheel 5732 is also difficult to rotate, ensuring that the stainless steel pipe can be clamped, which helps to improve cutting efficiency.

[0089] Reference Figure 1The measuring component 46 includes a positioning plate 461, a reading line 462, and a scale line 463. The positioning plate 461 is fixedly connected to the end of the first three-jaw chuck 2 away from the second three-jaw chuck 51. The reading line 462 is located on the side wall of the moving platform 43, and the reading line 462 and the end of the positioning plate 461 near the first three-jaw chuck 2 are in the same plane. The scale line 463 is located on the side wall of the base 1, and the reading line 462 and the scale line 463 are on the same side. The origin of the scale line 463 and the end of the cutting device 3 near the moving platform 43 are in the same plane.

[0090] In use, one end of the stainless steel pipe is abutted against the positioning plate 461, and then the first three-jaw chuck 2 clamps the stainless steel pipe. Immediately afterwards, the moving platform 43 moves away from the clamping mechanism. When the reading line 462 reaches the position on the scale line 463 where the required cutting length is desired, the moving platform 43 is locked. At this point, the cutting device 3 cuts the stainless steel pipe, achieving synchronization of measurement and cutting, which improves cutting efficiency.

[0091] The implementation principle of the stainless steel pipe cutting and positioning device in this embodiment is as follows: In use, one end of the stainless steel pipe is abutted against the positioning plate 461, and then the stainless steel pipe is clamped by the first three-jaw chuck 2. The lead screw 441 is rotated, and its torque is transmitted sequentially to the third bevel gear 56 through a set transmission component. The third bevel gear 56 meshes with a rotating ring 55 located on its side, thereby driving the rotating ring 55 to rotate synchronously. The rotation of the rotating ring 55 further drives the second bevel gear 54, which meshes with it, to rotate; the second bevel gear 54 meshes with the first bevel gear 53 at an angle, and the first bevel gear 53 rotates accordingly, driving the rotating shaft 52, which is coaxially connected to it, to rotate. The rotation of the rotating shaft 52 drives the second three-jaw chuck 51 to operate through a linkage structure, realizing automatic clamping of the stainless steel pipe. When the stainless steel pipe is not the required length, the isolation plate 5733 is slid between the first magnetic wheel 5731 and the second magnetic wheel 5732. Rotating the second magnetic wheel 5732 releases the stainless steel pipe from the second three-jaw chuck 51. Reversing the rotation of the first magnetic wheel 5731 allows the moving platform 43 to continue moving. When the moving platform 43 is locked and the stainless steel pipe is clamped, the isolation plate 5733 is moved away from the first magnetic wheel 5731. At this point, the moving platform 43 is locked, the first magnetic wheel 5731 cannot rotate, and the second magnetic wheel 5732 is also difficult to rotate, ensuring the stainless steel pipe is clamped. After cutting, during the resetting process of the moving platform 43, the screw 441 rotates, causing the second three-jaw chuck 51 to release the stainless steel pipe, shortening the time for adjusting the device during the next cut and improving cutting efficiency.

[0092] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
