Description

Technical Field

[0001] This invention relates to the field of cable processing, and in particular to a cable outer sheath circumferential cutting device and its control system. Background Technology

[0002] Cable sheath stripping is a core process in cable processing, inspection and maintenance. Its quality directly affects the insulation performance and service life of the cable. Traditional cable sheath stripping is mostly done manually with hand-held stripping tools or with simple mechanical assistance. This is not only inefficient, but also prone to scratching the internal core of the cable due to uneven force applied by the operator, leading to safety hazards such as cable insulation failure and short circuits. It is difficult to meet the needs of large-scale, high-precision production and maintenance. Summary of the Invention

[0003] The purpose of this application is to provide a cable outer sheath circumferential cutting device and its control system to solve the problem that traditional cable outer sheath stripping is mostly done manually with hand-held stripping tools or with simple mechanical assistance. This not only results in low work efficiency, but also easily damages the internal wire core of the cable due to uneven manual force, leading to cable insulation failure, short circuits and other safety hazards, and is difficult to meet the needs of large-scale, high-precision production and maintenance.

[0004] The cable outer sheath circumferential cutting device provided in this application adopts the following technical solution: It includes a workbench, a controller fixedly mounted on one side of the upper end of the workbench, two sliding grooves opened inside one end of the workbench, a movable seat slidably mounted inside the two sliding grooves, a fixed frame fixedly mounted on the upper end of the movable seat, multiple photoelectric sensors mounted on the side of the fixed frame via mounting strips, and the photoelectric sensors are electrically connected to the controller, first slide rails fixedly mounted on both sides of the fixed frame surface, two first sliders slidably mounted on the surfaces of the two first slide rails, a lifting platform fixedly mounted on the surfaces of the four first sliders, a photoelectric sensing sheet corresponding to the photoelectric sensors mounted on the surface of the lifting platform, a connecting frame fixedly mounted on the upper end of the lifting platform surface, a second slide rail fixedly mounted inside the connecting frame, a second slider slidably mounted on the surface of the second slide rail, a knife holder fixedly mounted on the surface of the second slider, a knife fixedly mounted inside the knife holder, and a micro switch electrically connected to the controller mounted on the surface of the connecting frame via a C-shaped frame, with the control button of the micro switch facing the knife holder. A mounting flange is fixedly installed on the lower end of one side of the workbench. A transmission spindle is rotatably installed inside the mounting flange via a bearing. A third driven synchronous wheel is fixedly sleeved on the outside of the transmission spindle. A fixed plate is fixedly installed on the upper end of the transmission spindle through the workbench. A three-jaw chuck is fixedly installed on the upper end of the fixed plate. By adopting the above technical solution, in actual use, the second motor is started. The second motor drives the second lead screw to rotate through the second active synchronous pulley, the second synchronous belt, and the second driven synchronous pulley, thereby driving the moving seat to move towards the cable. This causes the tool holder and the tool to approach the cable and cut. When the cutting force of the tool is too large, the tool will be subjected to the reaction force of the cable, which will push the tool holder to slide along the guide post towards the micro switch. At the same time, the spring will be compressed. When the tool holder contacts the control button of the micro switch, the micro switch will be triggered and send a signal to the controller. After receiving the signal, the controller controls the second motor to stop running, which in turn controls the moving seat to stop moving. In use, this can avoid the internal wire core being scratched or damaged due to excessive cutting of the cable, which could lead to cable insulation failure, short circuits, and other safety hazards.

[0005] Preferably, two first lead screw mounting seats are fixedly provided on the surface of the fixed frame, and a first lead screw is rotatably provided between the two first lead screw mounting seats. The first lead screw is threadedly connected to the lifting platform. By adopting the above technical solution, when the first lead screw rotates, it will drive the lifting platform to move, which in turn will drive the connecting frame, the tool holder, and the tool to move.

[0007] Preferably, a third slide rail is fixedly provided on both sides of the workbench surface, and two third sliders are slidably provided on the surfaces of the two third slide rails. One end of the movable seat passes through the sliding groove and is fixedly connected to the third slider. By adopting the above technical solution, the two third slide rails can play a guiding role when the moving seat moves, which can ensure that the moving seat moves smoothly during use, thereby increasing the stability of the moving seat.

[0008] Preferably, two second lead screw mounting seats are fixedly arranged on the surface of the worktable between two third slide rails, and a second lead screw is rotatably arranged between the two second lead screw mounting seats. A slide is threaded onto the external side of the second lead screw, and the slide is fixedly connected to the movable seat. Multiple photoelectric sensors are arranged on the surface of the worktable through mounting strips, and all multiple photoelectric sensors are electrically connected to the controller. The surface of the movable seat is provided with photoelectric sensing sheets corresponding to the photoelectric sensors. By adopting the above technical solution, when the second lead screw rotates, it will drive the slide table to move, which in turn will drive the moving seat to move, thereby driving the tool holder and the tool to move synchronously through the fixed frame.

[0009] Preferably, a second driven synchronous pulley is fixedly installed at one end of the second lead screw, a second motor mounting bracket is fixedly installed on the surface of the worktable, a second motor is fixedly installed on the surface of the second motor mounting bracket, the second motor is electrically connected to the controller, the output end of the second motor passes through the second motor mounting bracket and is fixedly installed with a second driving synchronous pulley, and a second synchronous belt is sleeved on the outside of the second driving synchronous pulley and the second driven synchronous pulley.

[0010] Preferably, two guide posts are fixedly provided on the surface of the connecting frame, one end of each guide post penetrates through the tool holder and is slidably connected to the tool holder, and springs are sleeved on the outside of each guide post, with both ends of the springs abutting against the surfaces of the connecting frame and the tool holder, respectively. By adopting the above technical solution, when the cutting force of the tool is too large during use, the tool will be subjected to the reaction force of the cable, which will push the tool holder to slide along the guide column, while the spring will be compressed.

[0011] Preferably, a third motor mounting bracket is fixedly installed at the lower end of the worktable corresponding to the mounting flange, and a third motor is fixedly installed at the lower end of the third motor mounting bracket. The third motor is electrically connected to the controller.

The controller is used to control the start, stop, and operating status of each motor and actuator of the device, and can preset and store multiple operating parameters. The micro switch is used to detect the moving position of the cutter holder and send a trigger signal to the controller. The photoelectric sensor is used to detect the lifting position of the lifting platform and the sliding position of the moving seat. The micro switch and the photoelectric sensor are electrically connected to the controller. The controller receives the detection signals sent by the micro switch and the photoelectric sensor, and controls the first motor, the second motor, the third motor, and the fourth motor in combination with the preset parameters. At the same time, the preset parameters can be adjusted and the operating status can be viewed through the controller's operating interface. Beneficial effects

[0013] In summary, this application includes at least one of the following beneficial technical effects: This invention provides a cable outer sheath circumferential cutting device and its control system. By incorporating a micro switch, spring, blade holder, guide column, second slide rail, second slider, and controller, the device activates a second motor during operation. The second motor, via a second driving synchronous pulley, a second synchronous belt, and a second driven synchronous pulley, drives a second lead screw to rotate, thereby moving the slide table and subsequently the moving seat towards the cable. This causes the blade holder and cutting tool to approach the cable and perform cutting. When the cutting force is excessive, the cutting tool experiences a reaction force from the cable, pushing the blade holder along the guide column towards the micro switch. Simultaneously, the spring is compressed. When the blade holder contacts the control button of the micro switch, the micro switch is triggered, sending a signal to the controller. Upon receiving the signal, the controller stops the second motor, which in turn stops the moving seat. This design prevents excessive cable cutting that could scratch or damage the internal wire core, leading to cable insulation failure, short circuits, and other safety hazards.

[0014] 2. This invention provides a cable outer sheath circumferential cutting device and its control system. The device comprises a first motor, a first motor mounting bracket, a first driving synchronous pulley, a first synchronous belt, a first driven synchronous pulley, a first lead screw mounting base, a first lead screw, a lifting platform, a first slide rail, a first slider, a mounting bracket, a controller, a second motor, a second driving synchronous pulley, a second driven synchronous pulley, a second synchronous belt, a second lead screw, a slide platform, a three-jaw chuck, a third motor, a fourth motor, a transmission spindle, a third driven synchronous pulley, a third driving synchronous pulley, and a third synchronous belt. In use, the third motor and the three-jaw chuck work together to clamp and fix the cable. Then, the first and second motors are started, driving the cutter to the cable cutting position. Then, the fourth motor is started, which drives the third active synchronous pulley to rotate. The third active synchronous pulley drives the third driven synchronous pulley to rotate synchronously via the third synchronous belt. This, in turn, drives the fixed plate, the three-jaw chuck, and the cable to rotate via the transmission spindle. At the same time, the second motor is started. The second motor drives the second driven synchronous pulley and the second lead screw to rotate via the second active synchronous pulley and the second synchronous belt. This drives the slide table and the moving seat to move. As the moving seat moves, it drives the tool holder and the tool to move towards the cable, so that the tool contacts the cable outer sheath and cuts the cable sheath. This achieves automated circumferential cutting of the cable outer sheath, reduces manual labor intensity, and improves work efficiency, making it suitable for large-scale cable circumferential cutting operations.

Two guide posts 20 are fixedly installed on the surface of the connecting frame 15. One end of each guide post 20 passes through the tool holder 18 and is slidably connected to the tool holder 18. Springs 21 are sleeved on the outside of each guide post 20. The two ends of the springs 21 abut against the surfaces of the connecting frame 15 and the tool holder 18, respectively. When the cutting force of the tool is too large during use, the tool will be subjected to the reaction force of the cable, which will push the tool holder 18 to slide along the guide post 20. At the same time, the springs 21 will be compressed. A mounting flange 33 is fixedly installed on the lower end of one side of the worktable 1. A transmission spindle 35 is rotatably installed inside the mounting flange 33 via a bearing. A third driven synchronous wheel 38 is fixedly sleeved on the outside of the transmission spindle 35.

The first lead screw 6 is threadedly connected to the lifting platform 9.

The worktable 1 is fixedly provided with third slide rails 25 on both sides of the surface. Two third sliders 26 are slidably provided on the surface of the two third slide rails 25. One end of the moving seat 3 passes through the sliding groove 2 and is fixedly connected to the third sliders 26. The two third slide rails 25 can guide the moving seat 3 when it moves, which can ensure that the moving seat 3 moves smoothly when in use, thereby increasing the stability of the moving seat 3. Two second lead screw mounting seats 22 are fixedly installed on the surface of the worktable 1 between two third slide rails 25. A second lead screw 23 is rotatably installed between the two second lead screw mounting seats 22. A slide table 24 is threaded onto the external surface of the second lead screw.

Multiple photoelectric sensors are installed on the surface of the worktable 1 via mounting strips, and all photoelectric sensors are electrically connected to the controller. The surface of the movable seat 3 is provided with photoelectric sensing plates corresponding to the photoelectric sensors. When the second lead screw 23 rotates, it will drive the slide table 24 to move, which in turn drives the movable seat 3 to move.

A second driven synchronous pulley 30 is fixedly installed at one end of the second lead screw 23. A second motor mounting bracket 27 is fixedly installed on the surface of the worktable 1. A second motor 28 is fixedly installed on the surface of the second motor mounting bracket 27. The second motor 28 is electrically connected to the controller 43. The output end of the second motor 28 passes through the second motor mounting bracket 27 and is fixedly installed with a second driving synchronous pulley 29. The second driving synchronous pulley 29 and the second driven synchronous pulley 30 are together fitted with a second synchronous belt 31. When the second motor 28 is started, the second motor 28 drives the second lead screw 23 to rotate through the second driving synchronous pulley 29, the second synchronous belt 31, and the second driven synchronous pulley 30. A third motor mounting bracket 32 ​​is fixedly installed at the lower end of the worktable 1, corresponding to the mounting flange 33. A third motor 34 is fixedly installed at the lower end of the third motor mounting bracket 32. The third motor 34 is electrically connected to the controller 43.

The third active synchronous pulley 41 and the third driven synchronous pulley 38 are together fitted with a third synchronous belt 42. The third motor 34 and the three-jaw chuck 37 cooperate to clamp the cable. Then the fourth motor 40 is started. The fourth motor 40 drives the third active synchronous pulley 41 to rotate. The third active synchronous pulley drives the third driven synchronous pulley 38 to rotate synchronously through the third synchronous belt 42. In turn, the transmission main shaft 35 drives the fixed disk 36, the three-jaw chuck 37 and the cable to rotate. This application also provides a control system for a cable sheath circumferential cutting device, including a controller 43, a photoelectric sensor, and a micro switch. The controller 43 is used to control the start-stop and operation status of each motor and actuator of the device. It can preset and store multiple operating parameters. The micro switch is used to detect the moving position of the cutter holder 18 and send a trigger signal to the controller 43. The photoelectric sensor is used to detect the lifting position of the lifting platform 9 and the sliding position of the moving seat 3. The micro switch and the photoelectric sensor are electrically connected to the controller 43. The controller 43 receives the detection signals sent by the micro switch and the photoelectric sensor, and controls the first motor 12, the second motor 28, the third motor 34, and the fourth motor 40 in combination with the preset parameters. At the same time, the preset parameters can be adjusted and the operating status can be viewed through the operating interface of the controller 43.

[0019] The implementation principle of this application embodiment is as follows: First, the cable to be processed is placed in the three-jaw chuck 37. Then, the third motor 34 is started. The output end of the third motor 34 drives the rotating shaft inside the three-jaw chuck 37 to rotate, causing the jaws of the three-jaw chuck 37 to retract and clamp the cable. Then, the first motor 12 is started. The first motor 12 drives the first driving synchronous pulley 13 to rotate. The first driving synchronous pulley 13 drives the first driven synchronous pulley 10 and the first lead screw 6 to rotate through the first synchronous belt 14. Since the first lead screw 6 is threadedly connected to the lifting platform 9, the rotation of the first lead screw 6 will drive the lifting platform 9 to move. The lifting platform 9 will drive the connecting frame 15, the tool holder 18 and the tool 19 to rise and fall synchronously until the tool 19 reaches the preset height. Then the second motor 28 will be started. The second motor 28 will drive the second active synchronous wheel 29 to rotate. The second active synchronous wheel 29 will drive the second driven synchronous wheel 30 to rotate synchronously through the second synchronous belt 31, which will drive the second lead screw 23 to rotate, thereby driving the slide table 24 to move, which will then drive the moving seat 3 to move along the third slide rail 25. The movement of the moving seat 3 will drive the fixed frame 4, the lifting platform 9, the tool holder 18 and the tool 19 to move horizontally until the tool 19 contacts the cable. Then, the fourth motor 40 and the second motor 28 are started simultaneously. The fourth motor 40 drives the third active synchronous pulley 41 to rotate. The third active synchronous pulley 41 drives the third driven synchronous pulley 38 to rotate synchronously through the third synchronous belt 42. At the same time, the rotation of the third driven synchronous pulley 38 will drive the transmission main shaft 35 to rotate. The transmission main shaft 35 will then drive the fixed plate 36, the three-jaw chuck 37 and the clamped cable to rotate. At the same time, the second motor 28 will drive the second active synchronous pulley 29 to rotate. The second active synchronous pulley 29 drives the second driven synchronous pulley 30 to rotate synchronously through the second synchronous belt 31. This will then drive the second lead screw 23 to rotate, thereby driving the slide table 24 and the moving seat 3 to move in the direction of the cable. The moving seat 3 will drive the tool holder 18 and the tool 19 to move towards the outer sheath of the cable.
