Description

Technical Field

[0001] This utility model relates to the field of cable anti-tangle technology, specifically to a cable anti-tangle structure and a machine tool having the same. Background Technology

[0002] In modern industrial manufacturing, CNC machine tools, as key processing equipment, are widely used for their efficient and precise machining capabilities. The electric spindle, as a core component of CNC machine tools, directly affects the machining efficiency and accuracy. However, in actual machining processes, the pipeline connection between the rotating and stationary parts of the electric spindle becomes a significant challenge. These pipelines, including power lines, encoder lines, air pipes, and hydraulic pipes, need to move relative to the rotating axis to transmit electricity, signals, gas, or liquids, with rotation angles reaching ±360°. This relative movement leads to entanglement between the rotating and stationary pipelines, severely impacting the normal operation and machining accuracy of the machine tool.

[0003] Entangled pipelines not only cause machine tool instability but can also lead to various malfunctions such as electrical short circuits, gas leaks, and liquid seepage. These malfunctions not only endanger operator safety but also cause equipment downtime and production delays, increasing maintenance costs. Furthermore, entangled pipelines exacerbate wear between pipelines, affecting the lifespan of pipelines and joints, thereby reducing the reliability and service life of the machine tool.

[0004] Currently, various solutions have been adopted in the industry to address the problem of rotating cable entanglement, such as cable management systems and slip ring devices. However, these solutions still have many shortcomings. For example, cable management systems are complex to maintain, requiring frequent disassembly and adjustment to ensure the normal operation of the rotating cable; while slip ring devices can reduce entanglement, their large size limits the flexibility of machine tool design; furthermore, these anti-entanglement devices have poor compatibility and are difficult to adapt to rotating cables of different specifications and quantities, resulting in limited applicability. Utility Model Content

[0005] The main purpose of this utility model is to provide a cable anti-tangling structure and a machine tool having it, so as to solve the problems of cumbersome maintenance, large space occupation, and poor adaptability in the prior art in preventing rotating cables from tangling.

[0006] To achieve the above objectives, according to one aspect of the present invention, a cable anti-tangling structure is provided, comprising: a fixed spool having a hollow channel for the passage of a rotating cable; a fixed rotating reel rotatably mounted on the fixed spool and axially fixed relative to the fixed spool, the fixed rotating reel having a limiting groove for supporting and limiting the rotating cable; and a movable rotating reel rotatably mounted on the fixed spool and axially movable along the fixed spool to adjust its axial position relative to the fixed spool according to the rotation direction and tension changes of the rotating cable.

[0007] Furthermore, there are multiple movable rotating reels, including a first movable rotating reel and a second movable rotating reel, which are arranged alternately on the fixed reel.

[0008] Furthermore, the cable anti-tangling structure also includes a reset component. Both the fixed rotating reel and the movable rotating reel include a reel body and a reset component. The reset component is connected to the reel body and the fixed reel body respectively to generate a reset torque when the rotating pipeline twists, so that the rotating pipeline can automatically return to its initial position under the action of the reset component when it is not affected by external force.

[0009] Furthermore, the reset component is a reset spring, one end of which is connected to the main body of the wire reel, and the other end of which is connected to the fixed wire drum; and / or both the fixed rotating wire reel and the movable rotating wire reel include multiple reset components, which are arranged at circumferential intervals along the corresponding wire reel main body.

[0010] Furthermore, the movable rotating coil includes a coil body and a tension detection module. The tension detection module is mounted on the coil body and is used to monitor the tension of the rotating pipeline in real time in order to control the axial movement of the movable rotating coil.

[0011] Furthermore, the tension detection module includes a pressure sensor located on the coil body and in contact with the rotating cable to determine the tension of the rotating cable based on the pressure applied to the pressure sensor by the rotating cable; and / or the coil body is provided with a locking groove for locking the rotating coil, and the pressure sensor is installed in the locking groove.

[0012] Furthermore, the fixed spool is provided with a slide rail that extends axially along the fixed spool; and / or the movable rotating spool includes a spool body and a movable bearing mounted on the spool body, the movable bearing being sleeved on the fixed spool, and the movable bearing being provided with a slide rail that cooperates with the slide rail.

[0013] Furthermore, there are multiple fixed rotating reels, including a first fixed rotating reel and a second fixed rotating reel, which are spaced apart. A movable rotating reel is disposed between the first and second fixed rotating reels. The first fixed rotating reel has a first locking member for locking the rotating pipeline, so as to fix the rotating pipeline relative to the reel body of the first fixed rotating reel by means of the first locking member. The rotating pipeline is movably limited on the second fixed rotating reel along the axial direction of the second fixed rotating reel.

[0014] Furthermore, the movable rotating coil includes a coil body and a second locking component. The coil body is provided with multiple locking slots, which are arranged sequentially along the circumference of the coil body. The second locking component is arranged around the coil body to limit the multiple rotating pipelines one by one in the multiple locking slots.

[0015] According to another aspect of the present invention, a machine tool is also provided, including a machine tool bed and a cable anti-winding structure mounted on the machine tool bed, wherein the cable anti-winding structure is the aforementioned cable anti-winding structure.

[0016] Applying the technical solution of this utility model, the cable anti-tangling structure of this utility model includes a fixed spool with a hollow channel for the passage of a rotating cable; a fixed rotating reel, which is rotatably sleeved on the fixed spool and axially fixed relative to the fixed spool, and has a limiting groove for supporting and limiting the rotating cable; and a movable rotating reel, which is rotatably sleeved on the fixed spool and axially movable along the fixed spool to adjust its axial position relative to the fixed spool according to the rotation direction and tension changes of the rotating cable. Thus, this utility model, by setting up a fixed spool, a fixed rotating spool, and a movable rotating spool, with the fixed rotating spool and the movable rotating spool rotatably mounted on the fixed spool, effectively prevents the rotating pipeline 100 from tangling during high-speed rotation by rotating the fixed rotating spool and driving the fixed rotating spool and the movable rotating spool to rotate when the rotating pipeline 100 twists. Furthermore, the limiting groove on the fixed rotating spool ensures the orderly rotation of the rotating pipeline. During use, the movable rotating spool can automatically adjust its axial position according to the tension changes of the rotating pipeline, providing necessary length compensation for the rotating pipeline 100 and avoiding tangling caused by length changes during rotation and reverse rotation. The orderly management of the rotating pipeline in this utility model reduces the risks of electrical short circuits, gas leaks, or liquid leaks, and also reduces the probability of mechanical failures caused by pipeline tangling, ensuring the safe operation of the machine tool under various processing conditions.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 2 As shown, the cable anti-tangling structure of this utility model includes: a fixed cable drum 10, having a hollow channel for the passage of a rotating cable tube 100; a fixed rotating cable reel 20, which is rotatably sleeved on the fixed cable drum 10 and fixed relative to the axial direction of the fixed cable drum 10, and has a limiting groove 210 for supporting and limiting the rotating cable tube 100; and a movable rotating cable reel 30, which is rotatably sleeved on the fixed cable drum 10 and movable along the axial direction of the fixed cable drum 10, so as to adjust the axial position of the movable rotating cable reel 30 relative to the fixed cable drum 10 according to the rotation direction and tension change of the rotating cable tube 100.

[0027] As can be seen, this utility model, by setting up a fixed spool, a fixed rotating spool, and a movable rotating spool, and by rotatably mounting the fixed rotating spool and the movable rotating spool on the fixed spool, effectively prevents the rotating pipeline 100 from tangling during high-speed rotation by rotating the fixed rotating spool and driving the fixed rotating spool and the movable rotating spool to rotate. Furthermore, the limiting groove on the fixed rotating spool ensures the orderly rotation of the rotating pipeline. During use, the movable rotating spool can automatically adjust its axial position according to the tension changes of the rotating pipeline, providing necessary length compensation for the rotating pipeline 100 and avoiding tangling caused by length changes during rotation and reverse rotation. The orderly management of the rotating pipeline in this utility model reduces the risks of electrical short circuits, gas leaks, or liquid leaks, and also reduces the probability of mechanical failures caused by pipeline tangling, ensuring the safe operation of the machine tool under various processing conditions.

[0028] Optionally, there are multiple movable rotating reels 30, including a first movable rotating reel 310 and a second movable rotating reel 320, which are arranged alternately on the fixed reel 10.

[0029] By setting multiple movable rotating reels 30, the tension and position of the rotating cable can be controlled more precisely. This is suitable for equipment with long cables or requiring a larger rotation range, such as large robotic arms and aerial work platforms. It ensures that the rotating cable remains in good condition during complex movements and avoids equipment failures caused by cable problems.

[0030] like Figure 2 As shown, the cable anti-tangling structure also includes a reset component 40. Both the fixed rotating reel 20 and the movable rotating reel 30 include a reel body 50 and a reset component 40. The reset component 40 is connected to both the reel body 50 and the fixed reel 10 to generate a reset torque when the rotating cable 100 twists, so that the rotating cable 100 automatically returns to its initial position under the action of the reset component 40 when not affected by external forces. The reset component 40 enables the cable to automatically reset after twisting, reducing the need for manual intervention. It is suitable for equipment that requires frequent rotation, improving the automation level and operating efficiency of the equipment.

[0031] Preferably, the reset component 40 is a reset spring, with one end of the reset spring connected to the main body 50 of the wire reel and the other end of the reset spring connected to the fixed wire drum 10. Using a reset spring as the reset component results in a simple structure, low cost, and the ability to provide a stable reset force, making it suitable for equipment of various sizes.

[0032] Preferably, both the fixed rotating reel 20 and the movable rotating reel 30 include multiple reset components 40, which are arranged at circumferential intervals along the respective reel bodies 50. This arrangement of multiple reset components 40 allows for a more even distribution of the reset force, ensuring accurate cable reset during high-precision rotation operations, reducing measurement errors and experimental deviations, and improving the quality of scientific research and production.

[0033] In this invention, the movable rotating reel 30 includes a reel body 50 and a tension detection module. The tension detection module is mounted on the reel body 50 and is used to monitor the tension of the rotating pipeline 100 in real time to control the axial movement of the movable rotating reel 30. The introduction of the tension detection module enables the cable anti-tangling structure to automatically adjust according to the real-time tension of the cable, effectively preventing equipment malfunction caused by excessive stretching or slack in the cable, and enhancing the reliability of the equipment.

[0034] In this invention, both the first movable rotating coil 310 and the second movable rotating coil 320 are equipped with tension detection modules to monitor the tension of the pipeline in real time. Where the tension is low, the length of the released pipeline is reduced, and where the tension is high, the length of the released pipeline is increased. Then, the pipeline tension between the coils is kept consistent by axial movement.

[0035] In one embodiment of the present invention, the tension detection module includes a pressure sensor located on the coil body 50 and in contact with the rotating pipeline 100, so as to determine the tension of the rotating pipeline 100 based on the pressure applied to the pressure sensor by the rotating pipeline 100.

[0036] In another embodiment of this utility model, the main body 50 of the coil is provided with a locking groove 330 for locking the rotating coil, and the pressure sensor is installed in the locking groove 330. The design of the locking groove 330 makes the installation of the pressure sensor more stable, ensuring the stability and accuracy of the pressure sensor, effectively avoiding equipment failure caused by vibration and impact, and improving the reliability of the equipment.

[0037] like Figure 2 As shown, the fixed spool 10 is provided with a slide rail 110, which extends axially along the fixed spool 10; and / or the movable rotating spool 30 includes a spool body 50 and a movable bearing mounted on the spool body 50. The movable bearing is sleeved on the fixed spool 10, and a slide rail that mates with the slide rail 110 is provided on the movable bearing. The cooperation of the slide rail 110 and the movable bearing makes the movement of the movable rotating spool smoother, reduces cable wear and failures caused by frequent axial movement, improves the reliability and service life of the equipment, and reduces maintenance costs.

[0038] like Figure 1As shown, there are multiple fixed rotating reels 20, including a first fixed rotating reel 220 and a second fixed rotating reel 230. The first fixed rotating reels 220 and the second fixed rotating reels 230 are spaced apart, and a movable rotating reel 30 is disposed between the first fixed rotating reels 220 and the second fixed rotating reels 230. The first fixed rotating reel 220 has a first locking component for locking the rotating cable 100, thereby fixing the rotating cable 100 relative to the reel body 50 of the first fixed rotating reel 220. The rotating cable 100 is movably limited on the second fixed rotating reel 230 along its axial direction. By setting multiple fixed rotating reels 20 and locking components, the rotation and movement of the cable can be controlled more precisely. Through the synergistic effect of multiple fixed rotating reels and locking components, high-precision cable positioning is achieved, significantly improving the processing accuracy and measurement accuracy of the equipment.

[0039] Preferably, the movable rotating reel 30 includes a reel body 50 and a second locking component. The reel body 50 has multiple locking slots 330 arranged sequentially along the circumference of the reel body 50. The second locking component surrounds the reel body 50 to correspondingly limit the multiple rotating cables 100 within the multiple locking slots 330. This design can handle multiple cables simultaneously, improving equipment integration and work efficiency. It is suitable for equipment requiring simultaneous operation of multiple cables, such as multi-axis CNC machine tools and multi-sensor integrated intelligent robots, ensuring efficient equipment operation and operational flexibility.

[0040] This utility model also provides a machine tool, including a machine tool bed and a cable anti-tangling structure mounted on the machine tool bed, wherein the cable anti-tangling structure is the aforementioned cable anti-tangling structure. This cable anti-tangling structure can not only significantly reduce machine tool downtime and maintenance costs, but also adapt to more complex and variable working environments, such as high temperature, high humidity, high dust and other harsh conditions, ensuring that the machine tool can operate stably in various environments.

[0041] In actual operation, the first fixed rotating reel 220 is fixed in the axial direction and can rotate in the circumferential direction. The pipeline is fixed in the limiting slot 210 and locked by the first locking component. The first movable rotating reel 310 and the second movable rotating reel 320 can move in the axial direction and can rotate in the circumferential direction. The pipeline is fixed in the locking slot 330 and locked by the second locking component. The second fixed rotating reel 230 is fixed in the axial direction and can rotate in the circumferential direction. The pipeline can move in the locking slot 330.

[0042] Preferably, the fixed spool 10 of this invention is hollow, and the hollow part is used to carry the fixed pipeline. Before the rotating pipeline rotates, all pipelines of various specifications and sizes are fixed parallel to each other on the limiting slot 210 and the locking slot 330 by the spool. At this time, the first fixed rotating spool 220, the first movable rotating spool 310, and the second movable rotating spool 320 all lock the pipeline, and the movement of the pipeline is consistent with the movement of these spools. The second fixed rotating spool 230 does not fix the pipeline, and the pipeline can be dragged up and down on the locking position, but the twisting of the pipeline will cause the spool to twist synchronously. At this time, the return spring is in the initial state. Regardless of whether the pipeline rotates clockwise or counterclockwise, the return spring will generate a return torque. The magnitude of the return torque can be adjusted according to the elastic coefficient of the return spring. A certain pipeline length margin is left between the first movable rotating spool 310 and the second movable rotating spool 320 to compensate for the length stretched when the pipeline twists. Secondly, tension detection modules are installed at the first moving rotating coil 310 and the second moving rotating coil 320 to monitor the tension of the pipeline in real time. Where the tension is low, the length of the released pipeline is reduced, and where the tension is high, the length of the released pipeline is increased. Then, the pipeline tension between the coils is kept consistent by axial movement.

[0043] The specific implementation of this utility model is as follows:

[0044] When the pipeline rotates clockwise (or counterclockwise) from 0° to +360° (-360°), all reels rotate clockwise (or counterclockwise). The rotational torque and angle of the reels gradually increase. At this time, the pressure sensor of the second moving rotating reel 320 detects excessive tension, so the moving reel moves axially downward to release the length allowance, allowing the pipeline to operate within the normal tension range during rotation. The pipeline rotates synchronously with the same tension, reducing mutual wear and preventing tangling. Conversely, when the pipeline rotates counterclockwise (or clockwise) from +360° (-360°) to 0°, all reels rotate counterclockwise (or clockwise) to reset. The rotational torque and angle of the reels gradually decrease. At this time, the pressure sensor of the second moving rotating coil 320 detects that the tension is too low. Therefore, the second moving rotating coil 320 will move upward axially to tighten the length allowance, so that the pipeline can work within the normal tension range when rotating. The pipeline will reset synchronously with the same tension, reducing mutual wear between pipelines and avoiding tangling.

[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0046] The cable anti-tangling structure of this utility model includes: a fixed cable drum 10 having a hollow channel for the passage of a rotating cable tube 100; a fixed rotating cable reel 20, which is rotatably sleeved on the fixed cable drum 10 and fixed relative to the axial direction of the fixed cable drum 10, and has a limiting groove 210 for supporting and limiting the rotating cable tube 100; and a movable rotating cable reel 30, which is rotatably sleeved on the fixed cable drum 10 and movable along the axial direction of the fixed cable drum 10, so as to adjust the axial position of the movable rotating cable reel 30 relative to the fixed cable drum 10 according to the rotation direction and tension change of the rotating cable tube 100.

[0047] As can be seen, this utility model, by setting up a fixed spool, a fixed rotating spool, and a movable rotating spool, and by rotatably mounting the fixed rotating spool and the movable rotating spool on the fixed spool, effectively prevents the rotating pipeline 100 from tangling during high-speed rotation by rotating the fixed rotating spool and driving the fixed rotating spool and the movable rotating spool to rotate. Furthermore, the limiting groove on the fixed rotating spool ensures the orderly rotation of the rotating pipeline. During use, the movable rotating spool can automatically adjust its axial position according to the tension changes of the rotating pipeline, providing necessary length compensation for the rotating pipeline 100 and avoiding tangling caused by length changes during rotation and reverse rotation. The orderly management of the rotating pipeline in this utility model reduces the risks of electrical short circuits, gas leaks, or liquid leaks, and also reduces the probability of mechanical failures caused by pipeline tangling, ensuring the safe operation of the machine tool under various processing conditions.
