Description

Technical Field

[0001] This utility model relates to the technical field of connecting pipe shearing, and in particular to a connecting pipe shearing device. Background Technology

[0002] Air conditioner split units often require connecting pipes for assembly. These connecting pipes arrive in rolls, meaning they are wound up for transport. For these rolls, manual secondary cutting to the appropriate length is necessary before use. Different air conditioner models or connecting pipes used to assemble different components require different lengths. Manual production necessitates using length measuring fixtures to correct the pipe lengths, making the unwinding and cutting process cumbersome and labor-intensive.

[0003] Patent CN114918990A discloses an automatic cutting device for drain hoses in cabinet air conditioners, including a roll release mechanism, a guiding mechanism, a feeding roller pressing mechanism, and a cutting mechanism. These mechanisms are mounted on a base plate. The cutting mechanism includes a cutter fixing plate, a cutter, and a cutting motor. The cutter is fixed to the cutter fixing plate, which is connected to the cutting motor. This technical solution, through the cooperation of an active feeding roller, a stepper motor, a controller, and a driven feeding roller, can realize the conveying, measurement, and pressing of the drain hose to be cut. By connecting the cutting motor to the controller, automatic fixed-length cutting of the drain hose can be achieved, reducing the labor intensity of employees and directly realizing staff reduction and efficiency improvement. However, this technical solution uses two pressure rollers to convey the hose from back to front. The conveyed portion is affected by friction at the front, making it difficult to discharge quickly and prone to stacking. It may also be caught in the pressure rollers again. At the same time, the hose is conveyed by the friction between the two pressure rollers, which is relatively unstable. Under long-term use, it is impossible to accurately guarantee the hose length. Furthermore, the hose is squeezed by the two pressure rollers, which causes deformation after conveying, posing a quality hazard and making it difficult to maintain the performance stability of the cut hose. Utility Model Content

[0004] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a connecting pipe cutting device. This device transmits the connecting pipe by clamping the front end of the connecting pipe with a clamp and driving the clamp and the connecting pipe to move. At the same time, the length of the connecting pipe is accurately defined by the driving status of the driving component, which improves the cutting accuracy and avoids the performance of the connecting pipe being affected during transmission.

[0005] A connecting pipe shearing device, comprising:

[0006] Unwinding assembly for supplying connecting tubing;

[0007] A clamping guide includes a clamp and a drive, the clamp being used to clamp a connecting pipe, and the drive driving the clamp to move away from the shearing member;

[0008] A shearing component is located between the unwinding assembly and the clamping guide, and is electrically connected to the driving component, for shearing the connecting tube according to the driving state of the driving component.

[0009] This application can determine the moving distance of the clamp and the front end of the connecting pipe based on the driving situation of the driving component. For example, if the driving component is a stepper motor or a cylinder, the moving distance of the clamp and the front end of the connecting pipe can be determined by the operation of the driving component. In this way, the length of the connecting pipe can be determined without measuring the length of the clamp and the connecting pipe it holds. At the same time, this application moves the connecting pipe by clamping it with the clamp. The clamp only abuts against the front end of the connecting pipe, which will not cause errors in the performance and length of the connecting pipe, ensuring the accurate determination of the length of the connecting pipe and improving the cutting efficiency and accuracy of the connecting pipe.

[0010] In a preferred embodiment of this invention, the unwinding assembly is provided with a rotating shaft, and the connecting tube is wound into a roll and nested on the outer periphery of the rotating shaft.

[0011] In this application, the connecting tube is a flexible tubular structure that is wound into a coil before being placed in the unwinding assembly. This facilitates the storage and handling of the connecting tube. When the connecting tube needs to be cut, the coiled connecting tube can be simply nested around the outside of the rotating shaft to achieve unwinding. By cooperating with the rotating shaft, this application improves unwinding efficiency while ensuring that the connecting tube is easy to store and transport.

[0012] In a preferred embodiment of this invention, the axis of rotation is perpendicular to the driving direction of the driving component.

[0013] In this application, if the axis of rotation is vertical, the direction of movement of the clamp is horizontal. When the clamp moves the front end of the connecting tube, the coiled connecting tube can be unwound around the axis of rotation, which improves the unwinding stability of the connecting tube in the unwinding assembly. At the same time, the tension of the clamp on the connecting tube can be kept to a minimum, which helps to reduce the power consumption of the drive component and ensures that the connecting tube can be unwound and moved smoothly.

[0014] In a preferred embodiment of this invention, a first support frame and a second support frame are also included. The unwinding assembly is disposed in the first support frame, and the clamping guide and the shearing member are disposed in the second support frame.

[0015] This application places the unwinding assembly in the first support frame and integrates the clamping guide and the shearing component in the second support frame. By adjusting the height of the first and second support frames, it ensures that the unwinding assembly, the clamping guide, and the shearing component are located in the same plane, such as in the same horizontal plane or the same inclined plane. This ensures that the movement, shearing, and unwinding of the connecting tube are all carried out in the same plane, thereby ensuring that the connecting tube remains on the same straight line as it passes through the shearing component and during the movement process, avoiding bending of the connecting tube's movement trajectory, and helping to improve the accuracy of the connecting tube length measurement.

[0016] In a preferred embodiment of this invention, a positioning component is provided in the first support frame, and the positioning component is located on the side of the unwinding component near the shearing component.

[0017] The positioning component is used to fix the front end of the connecting tube. Specifically, the positioning component can be a buckle or clamping element located in the first support frame. The driving component can move the clamp to the position of the positioning component to clamp the front end of the connecting tube. The front end of the connecting tube refers to the very front end of the coiled connecting tube on the rotating shaft. As the connecting tube is continuously cut, the front end of the coiled connecting tube is always defined as the new front end position, meaning that clamping, moving, and cutting to form the next fixed-length connecting tube begins from this point. In this application, the positioning component is used to fix the front end of the connecting tube, ensuring that the clamp can accurately clamp the connecting tube in the next clamping operation, avoiding the need for manual operation to place the connecting tube in the clamp position each time; it also avoids the need for the clamp to move to different positions on the coiled connecting tube each time to clamp the front end of the connecting tube. By limiting the front end of the connecting tube to a fixed position through the positioning component, the clamping efficiency of the clamp can be improved.

[0018] In a preferred embodiment of this invention, a collection box is provided on the side of the second support frame, and a conveyor belt is provided between the collection box and the clamp.

[0019] In this application, a collection box is used to collect and place the cut connecting pipe. A conveyor belt is provided between the collection box and the clamp. The conveyor belt can be an existing component with a transmission function. When the clamp moves the connecting pipe a set distance, it indicates that the length of the connecting pipe has reached a preset value. At this time, the shearing element intermittently cuts the connecting pipe. After being cut, the connecting pipe only needs to be released by the clamp to fall into the conveyor belt. The conveyor belt is used to transport the fallen connecting pipe to the collection box for collection and placement. In this application, the clamp and the shearing element can be electrically connected. Once the clamp receives the shearing signal from the shearing element, it can release the clamp, allowing the connecting pipe to fall. Preferably, the conveyor belt can be located below the clamp, so that the gravity of the connecting pipe can be used to make the connecting pipe fall onto the conveyor belt. In this application, the conveyor belt is located below the fixture, meaning that the conveyor belt is located below the movement stroke of the fixture. This is because the position of the fixture is not fixed during the movement of the connecting pipe driven by the fixture. Its specific position depends on the driving force of the driving component. In this application, the transmission line is set to be relatively long, which can cover all the movement trajectories of the fixture. This ensures that when the fixture drives the connecting pipe to different positions, the transmission from the connecting pipe in the fixture to the collection box can be realized.

[0020] In a preferred embodiment of this invention, the clamp drives the connecting pipe to move horizontally, and the conveyor belt is an inclined baffle disposed between the collection box and the clamp.

[0021] This application sets the axis of rotation vertically and the travel of the clamp horizontally. An inclined baffle is positioned below the clamp's travel distance, and a collection box is located at the bottom of the inclined baffle. After the clamp moves the front end of the connecting tube a set distance, the shearing component cuts the connecting tube. After shearing, the clamp releases the connecting tube, which then falls into the inclined baffle under gravity. The inclined baffle is a smooth plane, and under gravity, the connecting tube continues to fall along the inclined baffle into the collection box. The inclined baffle in this application allows for automatic collection of the connecting tube using its own weight and the inclined baffle, avoiding the additional power consumption associated with tube collection. Furthermore, the collection box and inclined baffle have a simple structure, eliminate power consumption, improve the collection efficiency of the cut connecting tube, and avoid the need for individual collection and placement of each cut connecting tube.

[0022] In a preferred embodiment of this invention, the driving component is a single-axis robot, and the clamp is fixedly connected to the single-axis robot.

[0023] A single-axis robot refers to a robot that moves in a straight line, meaning it drives a gripper and connecting pipe to reciprocate along the same straight line. When the single-axis robot moves the gripper and connecting pipe horizontally, a tilting baffle can be placed directly below the robot. Single-axis robots enable intelligent control, which helps improve the driving accuracy of the gripper, thereby precisely determining the movement distance of the gripper and connecting pipe, and improving the accuracy of connecting pipe shearing.

[0024] In a preferred embodiment of this invention, the single-axis robot includes a servo motor and a lead screw, wherein the servo motor drives the clamp to move away from the shearing workpiece via the lead screw.

[0025] The single-axis robot is equipped with a servo motor and a lead screw. By controlling the number of rotations of the servo motor and the lead screw, the movement distance of the gripper and the connecting pipe it holds can be precisely controlled. Since the starting point of the connecting pipe's movement is fixed, the length of the connecting pipe can be determined once the movement distance is determined. Therefore, it is possible to accurately control the timing of cutting connecting pipes of different lengths. At the same time, the servo motor drives the lead screw, which in turn drives the gripper and the connecting pipe to move. The overall accuracy is controllable and will not decrease after long-term use.

[0026] In a preferred embodiment of this invention, the shearing component includes a shearing blade and a shearing cylinder, the output end of which is connected to the shearing blade, and the shearing blade is located between the unwinding assembly and the clamping guide.

[0027] In this application, the shearing blade can be a component such as scissors, controlled by a shearing cylinder. When the shearing cylinder extends, it pushes the shearing blade to close, thus shearing the connecting pipe. When the shearing cylinder retracts, it drives the shearing blade to open, ensuring that the connecting pipe can pass smoothly between the shearing blades. The shearing cylinder of this application can be electrically connected to a clamp. After a preset time following the extension and retraction of the shearing cylinder, the clamp opens, causing the connecting pipe to fall, completing the shearing of a fixed length of connecting pipe. This application has a simple structure, is easy to operate, and helps improve the accuracy and efficiency of connecting pipe shearing.

[0028] The beneficial effects of this utility model are as follows:

[0029] This utility model provides a connecting pipe cutting device, including an unwinding assembly, a clamping guide, and a cutting component. The unwinding assembly supplies the connecting pipe; the clamping guide includes a clamp and a driving component. The clamp is used to clamp the connecting pipe, and the driving component drives the clamp to move away from the cutting component. The cutting component is located between the unwinding assembly and the clamping guide, and is electrically connected to the driving component, used to cut the connecting pipe according to the driving condition of the driving component. This application can determine the moving distance between the clamp and the front end of the connecting pipe based on the driving condition of the driving component. For example, the driving component is a stepper motor or a cylinder, and the moving distance between the clamp and the front end of the connecting pipe can be determined by the operation of the driving component. In this way, the length of the connecting pipe can be determined without measuring the length of the clamp and the connecting pipe it holds. At the same time, this application moves the connecting pipe by clamping it, and the clamp only abuts against the front end of the connecting pipe, which will not cause errors in the performance and length of the connecting pipe, ensuring accurate determination of the connecting pipe length and improving the cutting efficiency and accuracy of the connecting pipe.

[0038] Example 1

[0039] like Figures 1-3 As shown, a connecting pipe shearing device includes:

[0040] Unwinding assembly for supplying connecting tube 13;

[0041] A clamping guide includes a clamp 24 and a drive member, wherein the clamp 24 is used to clamp the connecting pipe, and the drive member drives the clamp 24 to move away from the shearing member;

[0042] A shearing member is located between the unwinding assembly and the clamping guide, and is electrically connected to the driving member, for shearing the connecting tube 13 according to the driving state of the driving member.

[0043] This application can determine the moving distance of the clamp 24 and the front end of the connecting tube 13 based on the driving situation of the driving component. For example, if the driving component is a stepper motor or a cylinder, the moving distance of the clamp 24 and the front end of the connecting tube 13 can be determined by the operation of the driving component. In this way, the length of the connecting tube 13 can be determined without measuring the length of the clamp 24 and the connecting tube 13 it holds. At the same time, this application moves the connecting tube 13 by clamping it with the clamp 24. The clamp 24 only abuts against the front end of the connecting tube 13, which will not cause errors in the performance and length of the connecting tube 13, ensuring the accurate determination of the length of the connecting tube 13 and improving the cutting efficiency and accuracy of the connecting tube 13.

[0044] Specifically, the driving component can be a servo motor. By controlling the number of rotations of the servo motor, the movement distance between the clamp 24 and the front end of the connecting tube 13 can be achieved. When the number of rotations of the servo motor reaches a preset value, it stops running. At this time, the shearing component cuts the connecting tube 13, thus achieving the cutting of a fixed length of connecting tube 13. In actual operation, the relationship between the number of rotations of the servo motor and the length of the connecting tube 13 can be determined through empirical values. Alternatively, the relationship between the servo motor and the length of the connecting tube 13 can be tested in advance to form a graph showing their correspondence. In actual operation, the corresponding number of rotations of the servo motor can be directly set according to the requirements of different lengths of connecting tube 13.

[0045] Specifically, the driving component can be a cylinder. By controlling the extension length of the cylinder, i.e., the extension stroke of the cylinder's extended end, the movement distance between the clamp 24 and the front end of the connecting pipe 13 can be achieved. When the extension length of the cylinder reaches a preset value, the cylinder stops running. At this time, the shearing component cuts the connecting pipe 13, thus achieving the cutting of a fixed length of connecting pipe 13. In actual operation, the relationship between the extension length of the cylinder and the length of the connecting pipe 13 can be determined through empirical values. Alternatively, the relationship between the lengths of the cylinder and the connecting pipe 13 can be tested in advance to form a graph showing their correspondence. In actual operation, the corresponding extension length of the cylinder can be directly set according to the requirements of different lengths of connecting pipe 13.

[0046] In this application, the movement direction of the clamp 24 is a straight line, that is, the driving component drives the clamp 24 and the front end of the connecting tube 13 it holds to move along a straight line. The translation along the straight line helps to determine the length of the connecting tube 13. At the same time, this application can also improve the shearing efficiency of the connecting tube 13 by increasing the running speed of the driving component, such as increasing the rotation speed of the servo motor or increasing the extension speed of the cylinder.

[0047] The driving precision of the driving component in this application is high. Even after running for a long time, its driving precision remains at a high level. This can maintain the accuracy of shearing the connecting pipe 13 in this application and avoid inaccurate control of the length of the connecting pipe 13 due to the long running time of the connecting pipe shearing device.

[0048] The clamp 24 of this application only abuts against the front end of the connecting pipe and clamps it, without interfering with the middle or rear end of the connecting pipe 13. During the stretching process of the connecting pipe 13, it will not cause deformation of the connecting pipe 13, thus avoiding the compression and deformation of the connected pipe 13 after shearing. It eliminates the quality risks that exist in the transmission and shearing process of the connecting pipe 13, and improves the quality stability of the connected pipe 13 after shearing while ensuring the accurate length of the connecting pipe 13.

[0049] In this application, the connecting tube 13 refers to a tubular structure with a certain degree of flexibility, ensuring that it can be clamped by the clamp 24. The connecting tube 13 in the unwinding assembly is a single unit, and its length is much greater than the required length of the connecting tube 13, that is, much greater than the length of the cut connecting tube 13. In the unwinding assembly, the connecting tube 13 can be wound into a roll or stacked, as long as it is ensured that when the clamp 24 clamps the front end of the connecting tube 13, it can smoothly pull the connecting tube 13 out of the unwinding assembly.

[0050] Example 2

[0051] like Figures 1-3 As shown, a connecting pipe shearing device includes:

[0052] Unwinding assembly for supplying connecting tube 13;

[0053] A clamping guide includes a clamp 24 and a drive member, wherein the clamp 24 is used to clamp the connecting pipe, and the drive member drives the clamp 24 to move away from the shearing member;

[0054] A shearing member is located between the unwinding assembly and the clamping guide, and is electrically connected to the driving member, for shearing the connecting tube 13 according to the driving state of the driving member.

[0055] Furthermore, the unwinding assembly is provided with a rotating shaft 12, and the connecting tube 13 is wound into a roll and nested on the outer periphery of the rotating shaft 12.

[0056] In this application, the connecting tube 13 is a flexible tubular structure. Before being placed in the unwinding assembly, it is wound into a coil, which facilitates the storage and handling of the connecting tube 13. When the connecting tube 13 needs to be cut, the coiled connecting tube 13 can be directly nested on the outside of the rotating shaft 12 to achieve unwinding. Through the cooperation of the coiled connecting tube 13 and the rotating shaft 12, this application can improve the unwinding efficiency while ensuring that the connecting tube 13 is easy to store and transport.

[0057] Furthermore, the axis of the rotating shaft 12 is perpendicular to the driving direction of the driving member.

[0058] In this application, if the axis of rotation shaft 12 is vertical, the movement direction of clamp 24 is horizontal. When clamp 24 moves the front end of the connecting tube, the coiled connecting tube 13 can be unwound around the axis of rotation shaft 12, which improves the unwinding stability of the connecting tube 13 in the unwinding assembly. At the same time, in this case, the tension of clamp 24 on the connecting tube 13 can be kept to a minimum, which helps to reduce the power consumption of the drive component and ensures that the connecting tube 13 can be unwound and moved smoothly.

[0059] Furthermore, it also includes a first support frame 11 and a second support frame 20, with the unwinding assembly disposed in the first support frame 11 and the clamping guide and shearing member disposed in the second support frame 20.

[0060] This application places the unwinding assembly in the first support frame 11 and integrates the clamping guide and the shearing component in the second support frame 20. By adjusting the height of the first support frame 11 and the second support frame 20, it ensures that the unwinding assembly, the clamping guide, and the shearing component are located in the same plane, such as in the same horizontal plane or the same inclined plane. This ensures that the movement, shearing, and unwinding of the connecting tube 13 are all carried out in the same plane, thereby ensuring that the connecting tube 13 remains on the same straight line as it passes through the shearing component and during the movement process, avoiding bending of the moving trajectory of the connecting tube 13, and helping to improve the accuracy of the length measurement of the connecting tube 13.

[0061] Furthermore, the first support frame 11 is provided with a positioning component 14, which is located on the side of the unwinding component near the shearing member.

[0062] The positioning component 14 is used to fix the front end of the connecting tube. Specifically, the positioning component 14 can be a buckle or clamping element set in the first support frame 11. The driving component can drive the clamp 24 to move to the position of the positioning component 14 to achieve clamping of the front end of the connecting tube 13. Here, the front end of the connecting tube 13 refers to the foremost position of the coiled connecting tube 13 on the rotating shaft 12. As the connecting tube 13 is continuously cut, the front end of the coiled connecting tube is always defined as the new front end position, that is, from this point onwards, clamping, moving, and cutting are performed to form the next fixed length of the connecting tube 13. In this application, the positioning component 14 is used to fix the front end of the connecting tube 13, which can ensure that the clamp 24 can accurately clamp the connecting tube 13 in the next clamping, avoiding the need for manual operation each time to place the connecting tube 13 in the position of the clamp 24; it can also avoid the need for the clamp 24 to move to different positions of the coiled connecting tube 13 each time to achieve clamping of the front end of the connecting tube 13. By limiting the front end of the connecting tube 13 to a fixed position by the positioning component 14, the clamping efficiency of the clamp 24 can be improved.

[0063] Furthermore, a collection box 26 is provided on the side of the second support frame 20, and a conveyor belt is provided between the collection box 26 and the clamp 24.

[0064] In this application, the collection box 26 is used to collect and place the cut connecting pipe 13. A conveyor belt is provided between the collection box 26 and the clamp 24. The conveyor belt can be an existing component with a transmission function. When the clamp 24 moves the connecting pipe 13 a set distance, it indicates that the length of the connecting pipe 13 has reached a preset value. At this time, the shearing component interrupts the connecting pipe 13. After being cut, the connecting pipe 13 only needs to be released by the clamp 24 to fall into the conveyor belt. The conveyor belt is used to transport the fallen connecting pipe 13 into the collection box 26 for collection and placement. In this application, the clamp 24 and the shearing component can be electrically connected. Once the clamp 24 receives the shearing signal from the shearing component, it can be released to allow the connecting pipe 13 to fall. Preferably, the conveyor belt can be set below the clamp 24, so that the connecting pipe 13 can fall onto the conveyor belt by gravity. In this application, the conveyor belt is located below the clamp 24, meaning that the conveyor belt is located below the travel distance of the clamp 24. This is because the position of the clamp 24 is not fixed during the movement of the connecting pipe 13 driven by the clamp 24. Its specific position depends on the driving force of the driving component. In this application, the transmission line is set to be relatively long, which can cover all the movement trajectories of the clamp 24. This ensures that when the clamp 24 drives the connecting pipe 13 to different positions, the transmission from the connecting pipe 13 to the collection box 26 can be achieved.

[0065] Furthermore, the clamp 24 drives the connecting pipe 13 to move in the horizontal direction, and the conveyor belt is an inclined baffle 25 disposed between the collection box 26 and the clamp 24.

[0066] In this application, the axis of rotation 12 is vertical, and the travel of clamp 24 is horizontal. An inclined baffle 25 is positioned below the travel of clamp 24, and a collection box 26 is located at the bottom of the inclined baffle 25. After clamp 24 moves the front end of connecting pipe 13 a set distance, the shearing component cuts the connecting pipe 13. After cutting, clamp 24 releases the connecting pipe 13, which then falls into the inclined baffle 25 under gravity. The inclined baffle 25 is a smooth plane, and under gravity, the connecting pipe 13 continues to fall along the inclined baffle 25 into the collection box 26. The inclined baffle 25 in this application enables automatic collection of the connecting pipe 13 using the weight of the connecting pipe 13 and the inclined baffle 25, avoiding the additional power consumption generated during collection. Furthermore, the collection box 26 and the inclined baffle 25 have simple structures, do not waste power, improve the collection efficiency of the cut connecting pipe 13, and avoid the need for individual collection and placement of the cut connecting pipe 13.

[0067] Furthermore, the driving component is a single-axis robot 23, and the clamp 24 is fixedly connected to the single-axis robot 23.

[0068] The single-axis robot 23 refers to a robot whose movement direction is linear, meaning that the single-axis robot 23 drives the gripper 24 and the connecting pipe 13 to reciprocate along the same straight line. When the single-axis robot 23 drives the gripper 24 and the connecting pipe 13 to move horizontally, the tilting baffle 25 can be directly placed below the single-axis robot 23. The single-axis robot 23 can achieve intelligent control, which helps to improve the driving accuracy of the gripper 24, thereby accurately determining the moving distance of the gripper 24 and the connecting pipe 13, and improving the cutting accuracy of the connecting pipe 13.

[0069] Furthermore, the single-axis robot 23 includes a servo motor and a lead screw, and the servo motor drives the clamp 24 to move away from the shearing workpiece via the lead screw.

[0070] The single-axis robot 23 is equipped with a servo motor and a lead screw. By controlling the number of rotations of the servo motor and the lead screw, the movement distance of the clamp 24 and the connecting tube 13 can be precisely controlled. Since the starting point of the movement of the connecting tube 13 is fixed, the length of the connecting tube 13 can be determined once the movement distance is determined. Therefore, the timing of cutting connecting tubes 13 of different lengths can be precisely controlled. At the same time, the servo motor drives the lead screw, which in turn drives the clamp 24 and the connecting tube 13 to move. The overall accuracy is controllable and there will be no problem of accuracy degradation after long-term use.

[0071] Furthermore, the shearing component includes a shearing blade 21 and a shearing cylinder 22, the output end of which is connected to the shearing blade 21, and the shearing blade 21 is located between the unwinding assembly and the clamping guide.

[0072] In this application, the shearing blade 21 can be a component such as scissors, and it is controlled by the shearing cylinder 22. When the shearing cylinder 22 extends, it pushes the shearing blade 21 to close, thereby cutting the connecting pipe 13. When the shearing cylinder 22 retracts, it drives the shearing blade 21 to open, ensuring that the connecting pipe 13 can pass smoothly between the shearing blades 21. The shearing cylinder 22 can be electrically connected to the clamp 24. After a preset time following the extension and retraction of the shearing cylinder 22, the clamp 24 opens, causing the connecting pipe 13 to fall, completing the cutting of a fixed length of connecting pipe 13. This application has a simple structure and is easy to operate, which helps to improve the cutting accuracy and efficiency of the connecting pipe 13.

[0073] Example 3

[0074] like Figures 1-3 As shown, a connecting pipe shearing device includes an unwinding assembly, a clamping guide, and a shearing component.

[0075] like Figure 1As shown, the unwinding assembly is located in the first support frame 11 and is used to supply the connecting tube 13. Specifically, the top of the first support frame 11 is a planar structure used to house the rotating shaft 12. The rotating shaft 12 is rotatably connected to the first support frame 11 and does not require a driving force. When the connecting tube 13 is unwound, the rotating shaft 12 can drive the coiled connecting tube 13 to rotate, causing the connecting tube 13 to be stretched out. In other words, the rotational driving force of the rotating shaft 12 comes from the pulling force of the clamp 24 on the connecting tube 13, thereby realizing the unwinding of the connecting tube 13.

[0076] A positioning component 14 is provided on the side of the first support frame 11 near the second support frame 20. The positioning component 14 is specifically an openable and closable latch, which is electrically connected to the shearing component or the driving component. When the shearing component cuts the connecting pipe 13, the latch closes to fix the front end of the connecting pipe. Alternatively, when the driving component stops driving the clamp 24, the latch closes to fix the front end of the connecting pipe. Similarly, when the shearing component is not running, or when the driving component is moving the clamp 24, the latch opens to ensure that the connecting pipe 13 can move smoothly through the latch.

[0077] like Figure 2 As shown, the clamping guide and the shearing component are integrated in the second support frame 20. The clamping guide and the shearing component are located at the top of the second support frame 20. The clamping guide includes a clamp 24 and a single-axis robot 23. The clamp 24 is used to clamp the connecting pipe, and the single-axis robot 23 drives the clamp 24 to move away from the shearing component, that is, away from the first support frame 11. The single-axis robot 23 includes a servo motor and a lead screw. The servo motor drives the clamp 24 to move away from the shearing component via the lead screw. The single-axis robot 23 has a servo motor and a lead screw inside. By controlling the number of rotations of the servo motor and the rotation of the lead screw, the movement distance of the clamp 24 and the clamped connecting pipe 13 can be precisely controlled. Since the starting point of the movement of the connecting pipe 13 is fixed, the length of the connecting pipe 13 can be determined after the movement distance is determined. Therefore, precise control of the shearing timing of connecting pipes 13 of different lengths can be achieved.

[0078] The shearing assembly includes a shearing blade 21 and a shearing cylinder 22. The output end of the shearing cylinder 22 is connected to the shearing blade 21, which is located between the unwinding assembly and the clamping guide. The shearing blade 21 includes a first blade and a second blade hinged together. The first blade can be fixed in position. The output end of the shearing cylinder 22 is connected to the second blade. By extending and retracting the shearing cylinder 22, the second blade can be driven to close or open with the first blade. When the first and second blades are closed, the connecting tube 13 is sheared; when the first and second blades are open, the connecting tube 13 can pass smoothly through the shearing blade 21.

[0079] The shearing cylinder 22 of this application can be electrically connected to the clamp 24. After the shearing cylinder 22 extends and retracts within a preset time, the clamp 24 opens, causing the connecting pipe 13 to fall, thus completing the shearing of a fixed length of connecting pipe 13.

[0080] The shearing cylinder 22 described in this application is electrically connected to the single-axis robot 23. When the number of rotations of the servo motor in the single-axis robot 23 reaches a preset value, it indicates that the length of the connecting pipe 13 being stretched has reached a preset value. At this time, the servo motor stops rotating, the positions of the connecting pipe 13 and the clamp 24 are fixed, and the shearing cylinder 22 extends, so that the connecting pipe 13 is sheared.

[0081] A collection box 26 is provided on the side of the second support frame 20 of this application. Specifically, the collection box 26 is located below the side of the single-axis robot 23, that is, the height of the collection box 26 is less than the height of the single-axis robot 23. In this embodiment, the axis of rotation 12 is vertical, and the stroke of the single-axis robot 23 is horizontal. An inclined baffle 25 is provided below the single-axis robot 23, and the collection box 26 is provided at the bottom of the inclined baffle 25. That is, there is a height difference between the top of the single-axis robot 23 and the top of the collection box 26. The top of the collection box 26 is an open structure to facilitate the entry of the connecting pipe 13. After the clamp 24 moves the front end of the connecting pipe 13 a set distance, the shearing blade 21 cuts the connecting pipe 13. After cutting, the clamp 24 releases the connecting pipe 13. At this time, the connecting pipe 13 falls into the inclined baffle 25 under the action of gravity. The inclined baffle 25 is a smooth plane. Under the action of gravity, the connecting pipe 13 continues to fall into the collection box 26 along the inclined baffle 25.

[0082] In this application, the movement direction of the clamp 24 is a straight line, that is, the single-axis robot 23 drives the clamp 24 and the front end of the connecting tube 13 it holds to move along a straight line. The translation along the straight line helps to determine the length of the connecting tube 13. At the same time, this application can also improve the cutting efficiency of the connecting tube 13 by increasing the running speed of the single-axis robot 23, for example, by increasing the rotation speed of the servo motor.

[0083] The single-axis robot 23 in this application has high driving precision. Even after running for a long time, its driving precision remains at a high level. This can maintain the accuracy of shearing the connecting pipe 13 in this application and avoid inaccurate control of the length of the connecting pipe 13 due to the long running time of the connecting pipe shearing device.

[0084] The clamp 24 of this application only abuts against the front end of the connecting pipe and clamps it, without interfering with the middle or rear end of the connecting pipe 13. During the stretching process of the connecting pipe 13, it will not cause deformation of the connecting pipe 13, thus avoiding the compression and deformation of the connected pipe 13 after shearing. It eliminates the quality risks that exist in the transmission and shearing process of the connecting pipe 13, and improves the quality stability of the connected pipe 13 after shearing while ensuring the accurate length of the connecting pipe 13.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0086] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
