Abstract
Description
Technical Field
[0001] This invention relates to the field of laser cutting technology, specifically to a follow-up intersecting line cutting machine and its application in the processing of parts in a prefabricated refrigeration station. Background Technology
[0002] The follow-up intersecting line cutting machine is a device that can accurately cut pipes, steel profiles and their assemblies. It is widely used in the cutting of intersecting line joints in many fields such as construction, shipbuilding, chemical industry, mechanical engineering, metallurgy, and power.
[0003] The working principle of the follow-up intersection line cutting machine is based on the mathematical principle of intersection lines and CNC cutting technology. The cutting head is controlled by a high-precision CNC system to move along the preset intersection line trajectory. The high temperature generated by the cutting wire melts the material to be cut, thus achieving precise cutting.
[0004] Because refrigeration plants need to conduct heat and prevent leaks, the connection strength and sealing of the corresponding pipelines are extremely important. For example, at the "T"-shaped connection between pipelines, if flanges are used directly, the gaskets may age or deform due to the large gas flow and pressure conditions in the application environment, which may lead to sealing failure. Therefore, intersecting line cutting and sealing welding are often used. Before welding, the intersecting line needs to be cut at the corresponding position.
[0005] In the actual cutting process, the trajectory of the intersection line is a three-dimensional trajectory, which is the common line of two intersecting solid surfaces. In modern CNC technology, the cutting head of the intersection line performs the cutting action according to the preset trajectory, which is obtained by computer simulation. The specific method is to input the diameter of one pipe and the diameter of the other pipe, and then use computer simulation to obtain the three-dimensional intersection curve between the two, which is the intersection line.
[0006] For the construction of refrigeration plants, there are a large number of pipelines. Before the construction of the refrigeration plant, materials need to be prepared. After batches of pipelines of different specifications are transported to the construction site, they are processed again according to the actual construction requirements, layout and other factors. Due to the large number and specifications of pipes and the long actual construction period, under the long-term pressure deformation, collision and scratch deformation during loading and unloading, as well as natural oxidation and corrosion, the surface of the pipes will inevitably produce micro deformation, rust and other phenomena.
[0007] If the pipe is cut according to the theoretical dimensions during the cutting process, the actual dimensions will deviate from the theoretical dimensions due to the deformation of the pipe. This will cause the actual cutting point to protrude from the theoretical point or be recessed from the theoretical point. As a result, the distance between the cutting head and the pipe will decrease, which may cause the pipe to overheat and deform locally, resulting in the destruction of the uniformity of the cut and the decrease in accuracy. Alternatively, when the cutting head moves to the recessed position of the pipe, the increased distance between the cutting head and the pipe may cause uneven heating of the pipe, resulting in the pipe not being completely heated and cut. Summary of the Invention

[0015] A rotary measuring component is disposed on the follow-up cutting mechanism. A translation component connected to the follow-up cutting mechanism is disposed on the rotating plate. The translation component can adjust the distance between the cutting head and the rotary measuring component through the rotary measuring component.

[0018] As a further embodiment of the present invention: the guiding mechanism includes an inner ring sleeve fixed on the receiving plate, a first fixing block and a second fixing block fixed on the inner ring sleeve, a first guide groove that slides and engages with the limiting post on the outer wall of the inner ring sleeve, and a first guide rod that can be oscillatingly mounted on the inner ring sleeve and can respectively abut against the first fixing block and the second fixing block.
[0019] As a further embodiment of the present invention: the guiding mechanism further includes an outer ring sleeve fixed on the inner ring sleeve, a third fixing block and a fourth fixing block are fixed on the outer ring sleeve, a second guide groove is opened on the inner wall of the outer ring sleeve to slide and fit with the limiting post, and a second guide rod is oscillatingly installed on the outer ring sleeve to abut and cooperate with the third fixing block and the fourth fixing block respectively.
[0020] As a further embodiment of the present invention: the rotating assembly includes a second motor fixed on the receiving plate, and a transmission rod connected to the output shaft of the second motor is rotatably mounted on the receiving plate, the transmission rod being fixedly connected to the rotating plate.
[0021] As a further embodiment of the present invention: the rotating measuring component includes a positioning post slidably mounted on the sliding block, a limit ring fixed on the positioning post, and a first spring sleeved on the positioning post, with the two ends of the first spring abutting against the sliding block and the limit ring respectively.

[0023] As a further embodiment of the present invention: the translation component includes a bidirectional lead screw rotatably mounted on the rotating plate, a second threaded sleeve symmetrically arranged and threadedly connected to the bidirectional lead screw, the second threaded sleeve being fixedly connected to the sliding block, a guide post fixedly mounted on the rotating plate, a guide sleeve symmetrically arranged and slidably mounted on the guide post, the guide sleeve being fixedly connected to the sliding block.
[0024] The application of the follow-up intersecting line cutting machine in the processing of parts for prefabricated refrigeration stations includes the aforementioned follow-up intersecting line cutting machine.
[0025] Compared with the prior art, the beneficial effects of the present invention are: the present application can achieve precise cutting of pipes by cooperating with the positioning column and the cutting head. Specifically, the rotating measuring component can collect data on the trajectory of the required cutting on the pipe surface before cutting. After the data collection is completed, the cutting head is controlled to move to the required cutting point by the guiding mechanism and the follow-up cutting mechanism, so as to perform cutting processing on the pipe according to the collected data. This prevents the problem that the distance between the cutting head and the pipe surface is too large or too small due to unevenness or rust on the pipe surface, which would cause the cutting head to interfere with the pipe and be damaged, or that the heat source generated by the cutting head fails to melt the pipe, resulting in incomplete cutting.
[0026] The first spring ensures that the positioning pin remains in contact with the pipe surface. As the drive rod rotates, the positioning pin moves vertically according to the undulations of the pipe surface, and the detector collects the position data of the positioning pin in real time. When the drive rod completes its first rotation, data collection is finished, and the controller receives and processes this data in real time to understand the unevenness of the pipe surface.
[0027] When the cutting head cuts at protruding or recessed areas on the pipe surface, its position can be precisely adjusted based on collected data to allow for clearance or fill gaps, thus ensuring uniformity and accuracy in the cut. Simultaneously, this precise control effectively prevents interference between the cutting head and the pipe's outer wall, avoiding damage to the cutting head due to collisions, and improving the equipment's reliability and lifespan.
[0028] By utilizing the coordinated operation of the limiting post, the first guide groove, and the second guide groove, precise control is achieved to ensure the cutting head accurately reaches the predetermined cutting height when it moves to the initial detection point of the positioning post, regardless of the rotational speed of the transmission rod. Subsequently, the pipe is precisely cut based on the trajectory data collected by the positioning post. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0043] Please see Figures 1 to 11 In this embodiment of the invention, the follow-up intersecting line cutting machine includes:
[0044] A processing table 1 and a lifting assembly disposed on the processing table 1. The lifting assembly includes a guide rail 101 fixed on the processing table 1. A first motor 2 is fixed on the processing table 1. A one-way lead screw 3 connected to the output shaft of the first motor 2 is rotatably mounted on the processing table 1. A first threaded sleeve 4 is threadedly connected to the one-way lead screw 3. A sliding plate 5 slidably connected to the guide rail 101 is fixed on the first threaded sleeve 4. A receiving plate 6 is fixed on the sliding plate 5. A controller 7 is fixed on the receiving plate 6.
[0045] Also includes:
[0046] A rotating assembly is disposed on the receiving plate 6, and a rotating plate 10 is connected to the rotating assembly;
[0047] A follow-up cutting mechanism is provided on the rotating plate 10. A cutting head 25 is connected to the follow-up cutting mechanism. A guide mechanism is provided on the receiving plate 6. The guide mechanism can control the cutting head 25 to move in the vertical direction through the follow-up cutting mechanism.
[0048] A rotary measuring component is disposed on the follow-up cutting mechanism. A translation component connected to the follow-up cutting mechanism is disposed on the rotating plate 10. The translation component can adjust the distance between the cutting head 25 and the rotary measuring component through the rotary measuring component.
[0049] Specifically, when it is necessary to perform intersecting line cutting on the pipe, the pipe to be cut can be fixed at the clamping workpiece, and the required cutting position of the pipe is positioned to match the cutting head 25. At this time, under the action of the lifting component, the height of the receiving plate 6 is adjusted so that the rotating measuring component moves to a position that is in contact with the surface of the pipe. The movement of the translation component can be controlled according to the required cutting size of the pipe to adjust the distance between the cutting head 25 and the rotating measuring component. Under the action of the rotating component, the rotating plate 10 is controlled to move, thereby driving the rotating measuring component to move through the follow-up cutting mechanism. Under the action of the rotating measuring component, data is collected on the surface of the steel pipe to be cut. During the data collection process, under the action of the guiding mechanism, the cutting head 25 is controlled to move towards the pipe through the follow-up cutting mechanism. When the data collection is completed, the cutting head 25 moves to the required cutting position. At this time, the rotating plate 10 continues to move. Under the action of the controller 7, the movement of the cutting head 25 is precisely controlled through the follow-up cutting mechanism to achieve precise cutting of the pipe.
[0050] Preferably, since the intersecting line cutting requires high processing precision, uneven steel surfaces or rust may affect the cutting precision. Therefore, the data of the pipe to be cut is first collected by the rotating measuring component, and then the feed amount of the cutting head 25 is precisely controlled to achieve accurate cutting of the pipe.
[0051] Please see Figures 1-4 The rotating assembly includes a second motor 8 fixed on the receiving plate 6, and a transmission rod 9 rotatably mounted on the receiving plate 6 and connected to the output shaft of the second motor 8. The transmission rod 9 is fixedly connected to the rotating plate 10.
[0052] Please see Figures 1-4 , Figure 6 , Figure 10 , Figure 11 The follow-up cutting mechanism includes symmetrically arranged sliding grooves 1001 on the rotating plate 10. A sliding block 13 is slidably installed in the sliding groove 1001. A movable rod 19 is slidably installed on the sliding block 13. A limit post 20 is slidably installed on the movable rod 19. A driven component is provided on the movable rod 19. The driven component includes a movable plate 21 fixed to the end of the movable rod 19. A second spring 22 is sleeved on the movable rod 19. The two ends of the second spring 22 abut against the movable plate 21 and the sliding block 13, respectively. A cylinder 23 is fixed on the movable plate 21. A connecting plate 24 is fixed to the telescopic end of the cylinder 23. The connecting plate 24 is fixedly connected to the cutting head 25.
[0053] The rotation measurement assembly includes a positioning post 16 slidably mounted on the sliding block 13, a limit ring 1601 fixed on the positioning post 16, a first spring 17 sleeved on the positioning post 16, the two ends of the first spring 17 abutting against the sliding block 13 and the limit ring 1601 respectively, and a detector 18 fixed to the end of the positioning post 16.
[0054] Please see Figure 10 Specifically, detector 18 can detect the distance between transmission rod 9 and sliding block 13 when the transmission rod 9 rotates and collect this data. Controller 7 receives the data collected by detector 18 and controls the precise movement of cylinder 23 based on this data to ensure the feed depth of cutting head 25. At this time, the pipe can be fixed by clamping the workpiece, and the central axis of the pipe is aligned with the cutting head 25 and positioning post 16 on the same vertical reference plane. To ensure the cutting accuracy of the pipe, data on the required cutting trajectory on the pipe surface needs to be collected before cutting. The receiving plate 6 can be lowered to a certain height by the lifting assembly, so that the positioning column 16 abuts against the surface of the pipe and the distance between the detector 18 and the sliding block 13 is at the required processing position. Under the action of the limiting ring 1601, the first spring 17 is in a compressed state. At this time, under the action of the guiding mechanism, the movable rod 19 is controlled to move up and down by the limiting column 20 so that the distance between the movable plate 21 and the rotating plate 10 is minimized. The second spring 22 is in a compressed state. Under the action of the cylinder 23, the extension of the cutting head 25 is minimized by the connecting plate 24.
[0055] Subsequently, under the action of the translation component, the two sliding blocks 13 are controlled to move synchronously and at the same speed along the length direction of the slide groove 1001 according to the required cutting size, and the two sliding blocks 13 move in opposite directions to adjust the distance between the positioning post 16 and the cutting head 25, ensuring that the cutting head 25 and the positioning post 16 move to the required cutting position, and that the distance between the cutting head 25 and the positioning post 16 and the transmission rod 9 is equal. At this time, the second motor 8 works and drives the rotating plate 10 to move through the transmission rod 9, thereby controlling the movement of the positioning post 16 through the sliding block 13. The positioning post 16 will move in a circle along the circumferential side wall of the pipe. Under the action of the first spring 17, the positioning post 16... While moving around the transmission rod 9, the cutting head 25 continuously moves vertically to ensure that the positioning post 16 is always in contact with the pipe surface, thus ensuring the acquisition of the data required for the cutting position. When the transmission rod 9 rotates one revolution, it indicates that the data acquisition is complete. When the transmission rod 9 rotates half a revolution, the cutting head 25 moves to the initial position of the detection point of the positioning post 16. The guiding mechanism will control the movable rod 19 to move away from the receiving plate 6 through the limit post 20, causing the movable plate 21 to move. This, in turn, controls the cutting head 25 to move to the required cutting position through the cylinder 23, leaving a certain distance from the pipe surface. The transmission rod 9 continues to rotate, and the cutting head 25 cuts the pipe surface.
[0056] Preferably, the cutting head 25 uses high-temperature melting to achieve cutting. If the pipe surface is uneven or corroded, the first rotation of the transmission rod 9 is for data acquisition. During this process, the first spring 17 ensures that the positioning pin 16 remains in contact with the pipe surface. As the transmission rod 9 rotates, the positioning pin 16 moves vertically according to the undulations of the pipe surface, and the detector 18 collects the position data of the positioning pin 16 in real time. When the transmission rod 9 completes the first rotation, data acquisition is complete, and the controller 7 receives and processes this data in real time to understand the unevenness of the pipe surface.
[0057] When the transmission rod 9 completes half a turn, the cutting head 25 moves to the initial detection point of the positioning post 16. Based on the collected data, the controller 7 precisely controls the extension and retraction of the cylinder 23. This allows the cutting head 25 to precisely adjust its position according to the actual situation when cutting protruding or recessed areas on the pipe surface, enabling it to make way or compensate for gaps, thus ensuring the uniformity and accuracy of the cut. Simultaneously, this precise control effectively prevents interference between the cutting head 25 and the outer wall of the pipe, avoiding damage to the cutting head 25 due to collisions, and improving the reliability and service life of the equipment.
[0058] Please see Figures 3-9The guiding mechanism includes an inner ring sleeve 26 fixed on the receiving plate 6. A first fixing block 2605 and a second fixing block 2606 are fixed on the inner ring sleeve 26. A first guide groove is formed on the outer wall of the inner ring sleeve 26 to slide and engage with the limiting post 20. A first guide rod 27 is oscillatingly mounted on the inner ring sleeve 26 to abut against the first fixing block 2605 and the second fixing block 2606 respectively. The guiding mechanism also includes an outer ring sleeve 28 fixed on the inner ring sleeve 26. A third fixing block 2805 and a fourth fixing block 2806 are fixed on the outer ring sleeve 28. A second guide groove is formed on the inner wall of the outer ring sleeve 28 to slide and engage with the limiting post 20. A second guide rod 29 is oscillatingly mounted on the outer ring sleeve 28 to abut against the third fixing block 2805 and the fourth fixing block 2806 respectively.
[0059] It should be noted that the inner ring sleeve 26 is composed of two tubes with different inner diameters. One tube is sleeved on the transmission rod 9 and fixedly connected to the receiving plate 6. The first guide rod 27 and the second guide rod 29 can be controlled by an electromagnetic device to swing their angles. The electromagnetic device is fixed at the positions of the second fixed block 2606 and the fourth fixed block 2806, respectively. When the electromagnetic device is energized, the first guide rod 27 and the second guide rod 29 swing to the positions of the second fixed block 2606 and the fourth fixed block 2806, respectively. The first guide groove can be divided into multiple segments, namely the first annular groove 2601, the first spiral groove 2602, the second annular groove 2603, and the second spiral groove 2604. The second guide groove is also divided into multiple segments, namely the third annular groove 2801, the third spiral groove 2802, the fourth annular groove 2803, and the fourth spiral groove 2804. The spiral grooves 2604 are symmetrically arranged, with one end connected to each other and the other end connected to both ends of the first annular groove 2601. The connection point of the first spiral groove 2602 and the second spiral groove 2604 is connected to the second annular groove 2603. The third spiral groove 2802 and the fourth spiral groove 2804 are also symmetrically arranged, with one end connected to each other and the other end connected to both ends of the third annular groove 2801. The connection point of the third spiral groove 2802 and the fourth spiral groove 2804 is connected to the fourth annular groove 2803. The spiral number of the first spiral groove 2602, the second spiral groove 2604, the third spiral groove 2802, and the fourth spiral groove 2804 is one-quarter of a turn. Therefore, the opening size of the first annular groove 2601 and the third annular groove 2801 in the circumferential direction is half a turn, and the opening size of the second annular groove 2603 and the fourth annular groove 2803 is one turn.
[0060] Please see Figure 7 , Figure 8Before cutting, the two ends of the limiting post 20 are located in the first annular groove 2601 and the third annular groove 2801, respectively, and the two ends of the limiting post 20 are located in the middle position of the first annular groove 2601 and the third annular groove 2801, respectively. Under the action of the limiting post 20, the movable plate 21 is controlled by the movable rod 19 to be located at the end of the stroke in the direction of the rotating plate 10, so that the distance between the cutting head 25 and the rotating plate 10 is minimized, ensuring that the cutting head 25 will not interfere with the pipe before cutting. The initial measurement point of the positioning post 16 is half a circle away from the initial position of the cutting head 25. The two electromagnets are in the energized state and provide electromagnetic force to the first guide rod 27 and the second guide rod 29, respectively, so that the first guide rod 27 abuts against the second fixing block 2606 and the second guide rod 29 abuts against the fourth fixing block 2806. Under the action of the first guide rod 27, the second spiral groove 2604 is blocked, and under the action of the second guide rod 29, the fourth spiral groove 2804 is blocked.
[0061] When the required cutting trajectory needs to be measured, the second motor 8 controls the transmission rod 9 to rotate, thereby driving the rotating plate 10 to move. This, in turn, controls the positioning post 16 and the cutting head 25 to move around the transmission rod 9 via the sliding block 13. The sliding block 13 also drives the two ends of the limiting post 20 to slide along the trajectory of the first annular groove 2601 and the third annular groove 2801 via the movable rod 19. When the limiting post 20 moves away from the first annular groove 2601 and the third annular groove 2801, the two ends of the limiting post 20 will simultaneously enter the first spiral groove 2602 and the third spiral groove 2802 respectively, so that the movable plate 21 moves away from the rotating plate 10 via the movable rod 19. The cutting head 25 gradually moves towards the surface of the pipe. When the transmission rod 9 rotates half a turn, the cutting head 25 moves to the initial detection point of the positioning post 16. At this time, the two ends of the limiting post 20 are respectively located at the connection positions of the first spiral groove 2602, the second spiral groove 2604, the second annular groove 2603, the third spiral groove 2802, the fourth spiral groove 2804, and the fourth annular groove 2803, so that the cutting head 25 moves to the required cutting point. Under the action of the first guide rod 27 and the second guide rod 29, it is ensured that the two ends of the limiting post 20 can only slide along the trajectory of the second annular groove 2603 and the fourth annular groove 2803, respectively.
[0062] Subsequently, the transmission rod 9 continues to rotate. Since the subsequent movement trajectory of the cutting head 25 has been collected by the positioning post 16, under the action of the detector 18, the cylinder 23 can be controlled to precisely control the feed amount of the cutting head 25 according to the trajectory measured by the positioning post 16, so as to achieve precise cutting of the pipe. During this process, the two ends of the limiting post 20 always slide along the trajectory of the second annular groove 2603 and the fourth annular groove 2803. At this time, the limiting post 20 is located in the second annular groove 2603 and the fourth annular groove 2803, and is offset from the connection position of the first spiral groove 2602 and the third spiral groove 2802. The cutting head 25 is in the cutting state, and the solenoid can be controlled to be de-energized. Under the action of gravity, the first guide rod 27 and the second guide rod 29 move to the first fixed block 2 respectively. 605 and the third fixing block 2805 abut to seal the second annular groove 2603 and the fourth annular groove 2803 respectively. When the transmission rod 9 rotates one revolution again, the cutting head 25 moves to the initial detection point of the positioning post 16 again. The two ends of the limiting post 20 abut with the first guide rod 27 and the second guide rod 29 respectively. The cutting head 25 completes the cutting of the pipe. At this time, the transmission rod 9 continues to move, so that the two ends of the limiting post 20 enter the second spiral groove 2604 and the fourth spiral groove 2804 along the first guide rod 27 and the second guide rod 29 respectively, so that the movable rod 19 moves toward the initial height. When the transmission rod 9 rotates half a revolution again, the limiting post 20 returns to the initial position, and the positioning post 16 also returns to the initial position. The above steps are repeated to achieve precise cutting of the pipe.
[0063] Preferably, during the pipe cutting process, the difference between the pipe wall thickness and the required cutting size necessitates corresponding adjustments to the rotational speed of the transmission rod 9. This alters the cutting rate of the cutting head 25, ensuring optimal cutting accuracy. This application, through the coordinated operation of the limiting post 20 with the first and second guide grooves, successfully achieves precise control of the cutting head 25 to accurately reach the predetermined cutting height when it moves to the initial detection point of the positioning post 16, regardless of the rotational speed of the transmission rod 9. Subsequently, based on the trajectory data collected by the positioning post 16, precise cutting of the pipe is performed.
[0064] In contrast, if hydraulic or other drive sources are used to control the lifting and lowering of the movable rod 19, the lifting and lowering rate of the movable rod 19 must be frequently adjusted during the cutting operation to adapt to changes in pipe wall thickness and cutting dimensions. This undoubtedly increases the complexity and difficulty of the operation significantly. More seriously, this traditional method may cause the cutting head 25 to reach the cutting height prematurely. If there are uneven parts on the outer wall of the pipe, the risk of the cutting head 25 interfering with them will increase significantly, potentially leading to damage to the cutting head 25 and causing unnecessary trouble and economic losses to the production operation.
[0065] Please see Figures 1-4 , Figure 6 , Figure 10 The translation component includes a bidirectional lead screw 11 rotatably mounted on the rotating plate 10, a second threaded sleeve 12 symmetrically arranged and threadedly connected to the bidirectional lead screw 11, the second threaded sleeve 12 being fixedly connected to the sliding block 13, a guide post 14 fixedly mounted on the rotating plate 10, a guide sleeve 15 symmetrically arranged and slidably mounted on the guide post 14, the guide sleeve 15 being fixedly connected to the sliding block 13.
[0066] Furthermore, since the required cutting size varies each time, the rotation radius of the cutting head 25 and the positioning post 16 needs to be adjusted according to the cutting size. Therefore, when the cutting size needs to be adjusted, the bidirectional lead screw 11 rotates, and through the second threaded sleeve 12, it drives the sliding block 13 to slide along the length direction of the slide groove 1001, thereby driving the guide sleeve 15 to slide along the length direction of the guide post 14. Under the action of the guide post 14 and the guide sleeve 15, the stability of the movement of the sliding block 13 is increased. The sliding block 13 also drives the positioning post 16 and the movable rod 1 The movement of the transmission rod 9 drives the cutting head 25 to move. Since the threaded portions on both sides of the bidirectional lead screw 11 are symmetrically arranged, the second threaded sleeve 12 moves at the same speed on the bidirectional lead screw 11, ensuring that the distance between the cutting head 25 and the positioning post 16 and the transmission rod 9 is always equal. After the adjustment is completed, the bidirectional lead screw 11 stops rotating. The bidirectional lead screw 11 can be driven by a motor and has a self-locking effect, which ensures that the cutting head 25 and the positioning post 16 are fixed in position after moving to the required position, thereby ensuring the accuracy of cutting.
