Description

Technical Field

[0001] This application relates to the field of cable cone cutting technology, and more specifically, to a cable main insulation layer stress cone cutting device. Background Technology

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. At the cable splice, due to the two different insulating materials, the cable body insulation and the additional insulation, the electric field distribution is different from that of the cable body. This causes a certain potential difference between two adjacent points on the same layer of insulation, that is, the axial field strength, or axial stress. This causes the insulation near the conductor connection end to be cut into a conical surface, that is, the reactive force cone.

[0003] Currently, the stress cone cutting of the main insulation layer of cables is usually carried out manually with hand-held cutting tools. This results in poor quality of the stress cone cutting position, makes it difficult to standardize, and causes high labor intensity, which also affects the overall work process.

[0004] To address the aforementioned problems, this application provides a cable main insulation layer stress cone cutting device. Summary of the Invention

[0007] The rotating support assembly includes a rotating cylinder. A support clamp is provided on the lower side inside the rotating cylinder. Two fixing rods are fixedly installed at the connection between the bottom of the support clamp and the inner wall of the bottom end of the rotating cylinder. Movable clamps are symmetrically distributed on both sides above the support clamp.

[0014] Through the above technical solution, the drive component realizes the synchronous rotation drive of the two rotating cylinders.

[0015] Furthermore, the support adjustment assembly includes support plates fixedly connected to both sides of the bottom of the platform plate. A groove is provided in the middle of the bottom end of the support plate. Multiple rollers are linearly and uniformly fixedly installed on the inner wall of the upper end of the groove. The bottom ends of the multiple rollers roll in contact with a slide rail.

[0017] Furthermore, multiple mating holes are provided, all of which are opened on one side of the top of the base plate, and the multiple mating holes are linearly and uniformly distributed on one side of the top of the base plate.

[0018] Through the above technical solution, the support adjustment component can not only provide stable support for the platform plate, but also adjust the cutting position of the stress cone of the positioned cable.

[0036] Example:

[0037] This application discloses a cable main insulation layer stress cone cutting device. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The system includes a base plate 1, a platform plate 2 located above the middle of the base plate 1, rotating support components on both sides of the top of the base plate 1, and two sets of rotating support components symmetrically distributed on both sides of the platform plate 2. A drive component is located on the lower side of the middle of the platform plate 2, and the drive component is located between the lower sides of the two sets of rotating support components. A support adjustment component is located at the outer end of the bottom of the platform plate 2. A special-shaped frame 3 is fixedly installed on one side of the top of the platform plate 2, and a tapered cutting component is located at the top of the special-shaped frame 3.

[0038] The rotating support assembly includes a rotating cylinder 4. A support clamping plate 5 is provided on the lower side inside the rotating cylinder 4. Two fixing rods 6 are fixedly installed at the connection between the bottom of the support clamping plate 5 and the inner wall of the bottom end of the rotating cylinder 4. Movable clamping plates 7 are symmetrically distributed on both sides above the support clamping plate 5. A clamping cylinder 8 is fixedly installed at the connection between one end of the two movable clamping plates 7 and the inner wall of the upper side of the rotating cylinder 4. A ring groove 9 is embedded in the outer wall of the middle part of the rotating cylinder 4. A positioning seat 10 is rotatably sleeved on the outer wall of the middle part of the rotating cylinder 4 through the ring groove 9. The bottom of the positioning seat 10 is fixedly connected to the base plate 1. A first gear 11 is fixedly sleeved on the outer wall of one side of the rotating cylinder 4. A second gear 12 is provided directly below the first gear 11. A transmission chain 13 meshes with the outer wall of the second gear 12 and the first gear 11. Multiple anti-slip triangular grooves are linearly and evenly distributed on the opposite end faces of the support clamping plate 5 and the two movable clamping plates 7. The top of the support clamping plate 5 is at the same horizontal line as the top of the platform plate 2.

[0039] The drive assembly includes a rotating rod 14 located below the center of the platform plate 2. The two sides of the rotating rod 14 are respectively fixedly sleeved through the central cavities of two second gears 12. I-shaped shafts 15 are fixedly sleeved on both sides of the center of the rotating rod 14. Supports 16 are rotatably sleeved on the outer wall of the center of the I-shaped shafts 15, and the supports 16 are fixedly installed on the top of the base plate 1. The rotational cooperation between the I-shaped shafts 15 and the supports 16 allows for the passive rotation of the rotating rod 14 without hindering its passive rotation, while also ensuring the stability of the rotating rod 14. The rotating rod 14 has a fixed movable support and limiting effect. Both ends of the rotating rod 14 are fitted with metal bearings, and both ends of the rotating rod 14 are rotatably connected to the opposite end faces of the two positioning seats 10 on the lower side through the metal bearings. The drive assembly also includes a third gear 17 fixedly fitted to the outer wall of the middle part of the rotating rod 14. A fourth gear 18 is meshed on one side end of the third gear 17. A drive motor 19 is connected to one end face of the fourth gear 18 through a rotating shaft. The bottom end of the drive motor 19 is fixedly installed on the top of the base plate 1 through a pad.

[0040] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6The support and adjustment assembly includes support plates 20 fixedly connected to both sides of the bottom of the platform plate 2. A groove 21 is formed in the middle of the bottom end of each support plate 20. Multiple rollers 22 are linearly and uniformly fixedly installed on the inner wall of the upper end of the groove 21. The bottom ends of the multiple rollers 22 collectively roll in contact with a slide rail 23. The slide rail 23 is slidably sleeved through the inner wall of the lower side of the groove 21, and its bottom is fixedly connected to the base plate 1. The arrangement of multiple rollers 22 on the inner wall of the upper side of the groove 21 enables the support plate 20 to slide on the slide rail 23. While connecting, it can also effectively avoid the wear problem caused by direct contact between the two. The support adjustment component also includes an extension block 24 fixedly installed on the outer surface of the lower end of a front support plate 20. A screw rod 25 is threaded through one side of the extension block 24. A rotating wheel 26 is fixedly installed on the top of the screw rod 25, and a mating hole 27 is movably inserted into the bottom end of the screw rod 25. Multiple mating holes 27 are provided. Multiple mating holes 27 are all opened on one side of the top of the base plate 1, and multiple mating holes 27 are linearly and evenly distributed on one side of the top of the base plate 1.

[0041] The tapered cutting assembly includes a drive cylinder 28 fixedly installed on the inner side wall of the upper end of the irregular frame 3. A metal sleeve 29 is fixedly connected to the drive end of the bottom of the drive cylinder 28. A tapered cutting tool 30 is movably sleeved in the inner cavity of the lower side of the metal sleeve 29. The tapered cutting tool 30 is located above the middle of the platform plate 2. The upper end of the tapered cutting tool 30 and the metal sleeve 29 are fixedly assembled by locking bolts. The locking bolts include metal bolts and metal nuts that are screwed together. The locking bolts provided between the tapered cutting tool 30 and the metal sleeve 29 can not only make it easy to lock and fix the two in a stable sleeved state, but also make it easy to disassemble, maintain or replace the tapered cutting tool 30 when needed.

[0042] The implementation principle of this application embodiment is as follows: When in use, the whole is in a fully assembled state. The end of the cable to be cut is passed through the inside of the two rotating cylinders 4 in sequence. At this time, the cable is supported by the top of the platform plate 2 and the two supporting clamping plates 5 respectively. Then, while each clamping cylinder 8 is started synchronously, each movable clamping plate 7 is driven to move and achieve stable clamping and positioning of the cable.

[0043] While the screw 25 is being screwed by the rotating wheel 26, it can be inserted and fitted with different mating holes 27. During this process, the horizontally moving platform plate 2 is adjusted to the position of the cable to be cone-cut and supports it. At this time, the two side support plates 20 slide linearly on the outer wall of the two side slide rails 23, and each roller 22 slides on the slide rail 23. The platform plate 2 is passively displaced, which also drives the irregular frame 3 to be adjusted synchronously. The cone-cutting tool 30 is indirectly driven downward by the drive cylinder 28, so that its cutting head abuts against the upper outer surface of the cable. Based on the pre-measured value of the thickness of the main insulation layer of the cable, the subsequent downward driving distance of the drive cylinder 28 can be set.

[0044] When the drive motor 19 is started, the meshing of the fourth gear 18 and the third gear 17 indirectly causes the rotating rod 14 to rotate. While the rotating rod 14 drives the second gears 12 on both sides, the transmission chains 13 on both sides link the second gears 12 and the first gear 11, ultimately achieving the synchronous rotation of the rotating cylinders 4 on both sides. In conjunction with the rotational cooperation between the two positioning seats 10 and the outer wall grooves 9 of the two rotating cylinders 4, the cable is indirectly driven to rotate. During this process, the drive cylinder 28 sets the feed distance of the conical cutting tool 30 to achieve the main insulation layer stress cone cutting work at the required position of the cable, which facilitates the subsequent stripping operation of the insulation sheath at the conical cutting end of the cable.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
