Description

Technical Field

[0001] This utility model belongs to the technical field of cable end stripping equipment, and in particular relates to a semi-rigid coaxial cable end stripping machine. Background Technology

[0002] Currently, most semi-rigid coaxial cable stripping machines on the market, whether domestically produced or imported, employ pneumatic clamping devices combined with servo motor-driven cutter movement systems to cut the outer sheath and dielectric layer of semi-rigid coaxial cables. However, these devices exhibit the following main problems in practical applications:

[0003] 1. The universality of the clamping mechanism leads to a decrease in accuracy: Traditional stripping machines use the same clamping mechanism for all specifications of semi-rigid coaxial cables, lacking adaptability to cables of different diameters. This results in low clamping accuracy, affecting the straightness and cylindricity of the cable, and even leaving clamp marks on the cable surface, affecting the product appearance and signal transmission quality.

[0004] 2. Blind spots in stripping small-diameter cables: For semi-rigid coaxial cables with smaller diameters (such as 1.2mm), existing equipment has blind spots that are difficult to control precisely during axial and radial stripping, which limits its application in precision machining.

[0005] 3. Complex structure and difficult maintenance: The complex mechanical structure not only increases the manufacturing cost of the equipment, but also often requires professional after-sales service in case of failure, resulting in long maintenance cycles and affecting production efficiency. Utility Model Content

[0006] In view of the above-mentioned problems in the prior art, the present invention aims to provide a semi-rigid coaxial cable end stripping machine, which solves the problem that existing semi-rigid coaxial cable stripping machines leave clamp marks on the cable surface when cutting the cable end, affecting the product appearance.

[0007] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: A semi-rigid coaxial cable end stripping machine is provided, which includes a driving component, and the output end of the driving component is provided with a cutting and fixing blade assembly, which includes a rotating shaft, two tension blocks, two tension levers and a cable holder.

[0008] The driving component drives the rotating shaft to rotate around its own axis; the two tension blocks are arranged in the direction of the fixed end of the rotating shaft, and the two tension blocks are symmetrically arranged with the axis of the rotating shaft as the center;

[0009] The cylindrical outer wall of the rotating shaft has two mounting slots for mounting the two tension levers. Each tension lever is rotatably connected to the mounting slot via a connecting shaft. The resistance end of the tension lever is flush with the free end of the rotating shaft, and a cutting blade is provided on the resistance end of the tension lever.

[0010] The tension block and the tension lever are matched one-to-one. The force-applying end of the tension block and the tension lever are fixedly connected. A pre-tension spring is provided between the tension block and the outer circumferential wall of the rotating shaft.

[0011] The cable holder is fixed to the free end of the rotating shaft, and both the rotating shaft and the cable holder have hollow channels for the cable to be cut to pass through.

[0012] The basic principle of this semi-rigid coaxial cable end stripping machine is as follows: When it is necessary to strip the end of the cable to be cut, the end of the cable to be cut is first passed through the hollow channel in the cable holder and placed inside the rotating shaft. The depth of the cable to be cut inside the rotating shaft can be determined according to the actual processing requirements. The cable to be cut and the hollow channel in the cable holder are in clearance fit to prevent the cable to be cut from rotating with the cable holder. Then, the drive unit is started to drive the rotating shaft to rotate around its own axis. The rotating shaft drives two tension blocks to rotate. After the two tension blocks rotate, they are displaced radially along the rotating shaft under the action of centrifugal force, which drives two tension levers to rotate around the connecting shaft. This causes the cutting blade on the resistance end of the tension lever to press against the outer wall of the cable to be cut, fixing the cable to be cut. At the same time, the cutting blade can also rotate to achieve the cutting and stripping of the end of the cable.

[0013] Furthermore, the connecting shaft is positioned close to the free end of the rotating shaft. This arrangement allows the cutting blade on the tension lever to have a large shearing force, making it easier to strip the insulation from the cable end to be cut.

[0014] Furthermore, each tension lever has an adjusting bolt threaded to its free end near the rotating shaft. The bottom of each adjusting bolt passes vertically through the tension lever and contacts the bottom of the mounting groove. By turning the adjusting bolt, the distance between the tension lever and the bottom of the mounting groove is adjusted, ultimately adjusting the maximum cutting depth of the cutting blade. This satisfies the cutting depth requirements of semi-rigid coaxial cables of different specifications, improving the stripping efficiency of semi-rigid coaxial cables.

[0015] Furthermore, an axial positioning device is provided within the hollow channel of the rotating shaft, the axial positioning device including a positioning rod fixedly disposed inside the rotating shaft. By adjusting the position of the positioning rod inside the rotating shaft, the cutting position of the cable to be cut is positioned by length, ensuring the consistency of stripping the end of semi-rigid coaxial cables of the same specification.

[0016] Furthermore, as a specific arrangement of the driving component, the driving component includes a drive motor and a coupling, and the fixed end of the rotating shaft is fixedly connected to the output end of the drive motor through the coupling.

[0017] Furthermore, the semi-rigid coaxial cable end stripping machine also includes a control device. The control device includes a housing for covering the drive motor, an operation panel on the housing, and a controller electrically connected to the operation panel and the drive motor inside the housing. By adjusting the speed of the drive motor, the shearing force of the cutting blade is adjusted. The principle is as follows: the speed of the drive motor causes the tension block to generate a corresponding centrifugal force. This centrifugal force is amplified proportionally and transmitted to the cutting blade through a tension lever, ultimately achieving the purpose of adjusting the shearing force of the cutting blade.

[0018] Furthermore, the semi-rigid coaxial cable end stripping machine also includes a base, with the housing and drive motor both located on the upper surface of the base.

[0019] Furthermore, without the action of external force, the pre-tensioned spring pulls the tension block to move toward the axis of rotation.

[0020] Furthermore, the cutting edge of each cutting blade is arranged facing the axis of the rotating shaft, and when the rotating shaft is not rotating, the distance between the cutting edges of the two cutting blades is greater than the diameter of the cable to be cut. The purpose of this arrangement is to facilitate passing the end of the cable to be cut through the two cutting blades and placing it inside the rotating shaft.

[0021] Furthermore, the cable holder includes a fixing plate, which is fixedly connected to the free end of the rotating shaft by screws. A hollow channel is provided at the center of the fixing plate. The hollow channel is a circular through hole, and the diameter of the circular through hole matches the outer diameter of the cable to be cut.

[0022] Compared with existing semi-rigid coaxial cable stripping machines, the advantages of this invention are as follows:

[0023] 1. This utility model discloses a semi-rigid coaxial cable end stripping machine. A rotating shaft drives two tension blocks to rotate. After the two tension blocks rotate, they are displaced radially along the rotating shaft under the action of centrifugal force, which drives two tension levers to rotate around the connecting shaft. This causes the cutting blades on the resistance end of the tension levers to press against the outer wall of the cable to be cut, thus fixing the cable. At the same time, the cutting blades can also rotate to cut and strip the end of the cable. This not only allows for clamping and fixing of semi-rigid coaxial cables of different specifications, expanding the application range of the equipment, but also ensures that the clamping position of the cable to be cut is the cutting position, avoiding clamping marks on the cable surface and guaranteeing the appearance and signal transmission performance of the product.

[0024] 2. The semi-rigid coaxial cable end stripping machine of this utility model, by setting an adjusting bolt on the tension lever, can fix the maximum cutting depth of the cutting blade by adjusting the height of the adjusting bolt, which can meet the cutting depth requirements of semi-rigid coaxial cables of different specifications and improve the stripping efficiency of semi-rigid coaxial cables.

[0025] 3. The semi-rigid coaxial cable end stripping machine of this utility model sets an axial positioning device inside the rotating shaft to locate the length of the cable to be cut, thereby ensuring the consistency of the end stripping of semi-rigid coaxial cables of the same specification.

[0030] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0031] like Figures 1-3 As shown, this utility model provides a semi-rigid coaxial cable end stripping machine, including a base 15 and a control device. The control device includes a housing 13 disposed on the upper end face of the base 15, a controller disposed inside the housing 13, and an operation panel 14 electrically connected to the controller disposed on the housing 13. A driving component located inside the housing 13 is also disposed on the upper end face of the base 15. Specifically, the driving component includes a drive motor 11 and a coupling 12. The drive motor 11 is located inside the housing 13, and the output end of the drive motor 11 is fixedly connected to the input end of the coupling 12. A cutting and fixing blade assembly is disposed at the output end of the coupling 12.

[0032] In this embodiment, the cutting and fixing blade assembly includes a rotating shaft 1, two tension blocks 2, two tension levers 3, and a cable retainer 4. The fixed end of the rotating shaft 1 is fixedly connected to the output end of the drive motor 11 via the coupling 12, and the drive motor 11 drives the rotating shaft 1 to rotate around its own axis. Two tension blocks 2 are positioned at the fixed end of the rotating shaft 1, symmetrically arranged around the axis of the rotating shaft 1. Two mounting slots 5 are formed on the cylindrical outer wall of the rotating shaft 1 for mounting two tension levers 3. Each tension lever 3 is rotatably connected to the mounting slot 5 via a connecting shaft 6. The resistance end of the tension lever 3 is flush with the free end of the rotating shaft 1, and a cutting blade 7 is mounted on the resistance end of the tension lever 3. Tension blocks 2 and tension levers 3 are matched one-to-one, with the force-applying ends of the tension blocks 2 and 3 fixedly connected. A pre-tension spring 8 is positioned between the tension blocks 2 and the circumferential outer wall of the rotating shaft 1. Without external force, the pre-tension spring 8 pulls the tension blocks 2 towards the axis of the rotating shaft 1. The cutting edges of each cutting blade 7 are arranged towards the axis of the rotating shaft 1. When the rotating shaft 1 is not rotating, the distance between the cutting edges of the two cutting blades 7 is greater than the diameter of the cable 16 to be cut. The purpose of this design is to facilitate passing the end of the cable 16 to be cut through the two cutting blades 7 and placing it inside the rotating shaft 1.

[0033] The cable retainer 4 is fixed to the free end of the rotating shaft 1. Both the rotating shaft 1 and the cable retainer 4 have hollow channels for the cable 16 to be cut to pass through.

[0034] As a specific configuration of the cable holder 4, the cable holder 4 includes a fixing plate, which is fixedly connected to the free end of the rotating shaft 1 by screws. A hollow channel is provided at the center of the fixing plate. The hollow channel is a circular through hole, the diameter of which matches the outer diameter of the cable 16 to be cut. Specifically, a bearing can be installed inside the hollow channel at the center of the fixing plate. The outer ring of the bearing is fixed to the hollow channel, and the semi-rigid cable to be cut is clamped using a micro-clearance fit between the inner ring of the bearing and the outer cylinder of the cable.

[0035] The working principle of the semi-rigid coaxial cable end stripping machine is as follows: When it is necessary to strip the end of the cable 16 to be cut, the end of the cable 16 to be cut is first passed through the hollow channel in the cable holder 4 and placed inside the rotating shaft 1. The depth of the cable 16 to be cut inside the rotating shaft 1 can be determined according to the actual processing requirements. The cable 16 to be cut and the hollow channel in the cable holder 4 are clearance fit to prevent the cable 16 to be cut from rotating with the cable holder 4. Then, the drive unit is started to drive the rotating shaft 1 to rotate around its own axis. The rotating shaft 1 drives the two tension blocks 2 to rotate. After the two tension blocks 2 rotate, they are displaced radially along the rotating shaft 1 under the action of centrifugal force, which drives the two tension levers 3 to rotate around the connecting shaft 6. This causes the cutting blade 7 on the resistance end of the tension lever 3 to press against the outer wall of the cable 16 to be cut, fixing the cable 16 to be cut. At the same time, the cutting blade 7 can also rotate to cut and strip the end of the cable 16 to be cut.

[0036] In this embodiment, the semi-rigid coaxial cable end stripping machine uses a rotating shaft 1 to drive two tension blocks 2 to rotate. After the two tension blocks 2 rotate, they are displaced radially along the rotating shaft 1 under the action of centrifugal force, which drives two tension levers 3 to rotate around the connecting shaft 6. This causes the cutting blades 7 on the resistance end of the tension levers 3 to press against the outer wall of the cable 16 to be cut, thus fixing the cable 16. At the same time, the cutting blades 7 can also rotate to cut and strip the end of the cable 16. This not only allows for clamping and fixing of semi-rigid coaxial cables of different specifications, broadening the application range of the equipment, but also ensures that the clamping position of the cable 16 is the cutting position, avoiding clamping marks on the cable surface and guaranteeing the appearance and signal transmission performance of the product.

[0037] Meanwhile, by adjusting the speed of the drive motor 11, the shearing force of the cutting blade 7 can be adjusted. The principle is as follows: by adjusting the speed of the drive motor 11, the tension block 2 generates a centrifugal force of a corresponding magnitude. This centrifugal force is amplified and transmitted to the cutting blade 7 through the tension lever 3 in a certain proportion, thereby achieving the purpose of adjusting the shearing force of the cutting blade 7.

[0038] Preferably, but not limited to, the connecting shaft 6 is positioned close to the free end of the rotating shaft 1. This arrangement allows the cutting blade 7 on the tension lever 3 to have a large shearing force, making it easier to strip the insulation from the end of the cable 16 to be cut.

[0039] Specifically, each tension lever 3 has an adjusting bolt 9 threadedly connected to its free end near the rotating shaft 1. The bottom of each adjusting bolt 9 vertically passes through the tension lever 3 and contacts the bottom of the mounting groove 5. By turning the adjusting bolt 9, the distance between the tension lever 3 and the bottom of the mounting groove 5 is adjusted, thereby adjusting the maximum cutting depth of the cutting blade 7. This satisfies the cutting depth requirements of semi-rigid coaxial cables of different specifications and improves the stripping efficiency of semi-rigid coaxial cables.

[0040] Preferably, an axial positioning device is provided within the hollow channel of the rotating shaft 1, the axial positioning device including a positioning rod 10 fixedly disposed inside the rotating shaft 1. By adjusting the position of the positioning rod 10 inside the rotating shaft 1, the cutting position of the cable 16 to be cut is positioned to ensure the consistency of stripping the end of semi-rigid coaxial cables of the same specification. The positioning rod 10 can be fixed to the inside of the rotating shaft 1 by a threaded connection, so that the position of the positioning rod 10 inside the rotating shaft 1 can be adjusted by rotating the positioning rod 10.

[0041] In summary, the semi-rigid coaxial cable end stripping machine of this utility model can not only clamp and fix semi-rigid coaxial cables of different specifications, thus broadening the application range of the equipment, but also ensures that the clamping position of the cable to be cut is the cutting position, avoiding leaving clamp marks on the cable surface, thus guaranteeing the appearance and signal transmission performance of the product. This solves the problem that existing semi-rigid coaxial cable stripping machines leave clamp marks on the cable surface when cutting the cable end, affecting the appearance of the product.
