Description

Technical Field

[0001] This application relates to the field of cable processing technology, and more specifically, to a cable outer layer circumferential cutting and chamfering integrated trimming tool. Background Technology

[0002] As society's reliance on electricity continues to increase and the need for urban beautification grows, the cable coverage rate in urban areas is rising year by year. As the difficulty of cable operation gradually increases, 10kV medium-voltage distribution networks are the most common and widely used distribution network systems. Due to the limitations of high-voltage cable manufacturing processes, the maximum length of seamless cable manufacturing is 10km. It is necessary to process the joints of individual cables and splice multiple cables together to achieve ultra-long-distance transmission.

[0003] Currently, in the installation and connection of cables, it is usually necessary to remove the outer insulation layer of the cable and simultaneously perform chamfering and trimming of the cut edges of the outer insulation layer. However, the current method is usually done manually, which results in high labor intensity, poor quality of cable outer layer circumferential cutting and chamfering, and low work efficiency.

[0004] To address the aforementioned issues, this application provides an integrated tool for cable outer layer circumferential cutting and chamfering. Summary of the Invention

[0005] The technical solution of the integrated cable outer layer circumferential cutting and chamfering trimming tool provided in this application is as follows:

[0006] A cable outer layer circumferential cutting and chamfering integrated trimming tool includes a main rotating drum. Two fixed cylinders slide against each other on both sides of the main rotating drum. A U-shaped seat is fixedly installed at the connection point of the bottom outer walls of the two fixed cylinders, with the U-shaped seat located on the outer side of the bottom of the main rotating drum. A first gear is fixedly sleeved on the outer wall of the middle part of the main rotating drum. A second gear meshes with the bottom end of the first gear. One end face of the second gear is connected to a first motor via a first rotating shaft. The first motor is fixedly installed through the inner cavity of one side of the upper end of the U-shaped seat. A circumferential cutting tool and a chamfering tool are symmetrically arranged inside the main rotating drum. A first cylinder and a second cylinder are fixedly connected to opposite ends of the circumferential cutting tool and the chamfering tool. The non-driving ends of the opposite sides of the first cylinder and the second cylinder are fixedly installed on the inner side wall of the main rotating drum. Side cylinders are provided on opposite sides of the two fixed cylinders, and positioning components are provided on both side cylinders.

[0007] Through the above technical solution, the U-shaped seat achieves the function of connecting and supporting the structure above it.

[0008] Furthermore, each of the two fixed cylinders has a circular groove on one end face facing each other. Each side of the groove has a plurality of limiting shafts slidably sleeved on its inner wall. The plurality of limiting shafts are fixedly installed on both ends of the main rotating cylinder in a circumferentially uniform manner.

[0009] Through the above technical solution, the embedded groove and the limiting shaft achieve a rotating support effect for the main rotating drum.

[0010] Furthermore, a base plate is fixedly connected to the bottom of the U-shaped base, and mounting holes are provided through the four corners of the base plate. A control panel is fixedly installed on the middle of one side of the top of the base plate.

[0011] Through the above technical solution, the control panel realizes the connection and control of its powered devices.

[0012] Furthermore, the inner and outer diameters of the two side cylinders are the same as those of the main rotating cylinder and the fixed cylinder. The left side cylinder is fixedly connected to the left fixed cylinder, while a gap is left between the right side cylinder and the right fixed cylinder.

[0013] Furthermore, four through holes are evenly distributed around the circumference of the right-side side cylinder, and a sliding rod is slidably connected to the inner wall of each through hole, and each sliding rod is fixedly installed on one end face of the right-side fixed cylinder.

[0014] Through the above technical solution, the through hole and the sliding rod realize the displacement support function of the right side cylinder.

[0015] Furthermore, an extension plate is fixedly connected to one side of the outer wall of the bottom end of the right-side side cylinder, and a driving cylinder is fixedly connected to one side wall of the bottom end of the extension plate. The non-driving end of the driving cylinder is fixedly sleeved through the middle of the bottom end of the U-shaped seat.

[0016] Through the above technical solution, the extension plate and the drive cylinder provide driving force for the right side cylinder in its displacement state.

[0017] Furthermore, the positioning component includes a V-shaped wide plate located inside the side cylinder. The two ends of the middle part of the V-shaped wide plate are provided with notches, and a V-shaped narrow plate is fitted onto the middle part of the V-shaped wide plate without contact through the two notches. The V-shaped narrow plate and the V-shaped wide plate are distributed axially symmetrically on the upper and lower sides inside the side cylinder, and the outer ends of the middle parts of the V-shaped narrow plate and the V-shaped wide plate are jointly provided with a driving structure.

[0018] Through the above technical solutions, V-shaped wide plates and V-shaped narrow plates can achieve stable clamping and positioning of cables.

[0019] Furthermore, the driving structure includes a rotating rod located on one side outside the side cylinder. The outer walls on both sides of the rotating rod are provided with threaded grooves, and connecting arms are screwed onto the outer walls on both sides of the rotating rod through the threaded grooves. Connecting rods are fixedly connected to the side of each connecting arm away from the rotating rod. Both connecting rods are slidably sleeved through the inner cavity of the outer end of the side cylinder, and one end of each connecting rod is fixedly connected to the outer surface of the middle part of the V-shaped wide plate and the V-shaped narrow plate, respectively. I-shaped shafts are fixedly sleeved on both outer walls of the middle part of the rotating rod, and support plates are rotatably sleeved on the outer walls of the middle parts of the two I-shaped shafts. Both support plates are fixedly installed on the outer surface of the side cylinder.

[0020] Furthermore, the drive assembly also includes a third gear fixedly sleeved on the outer wall of the middle part of the rotating rod, a fourth gear meshing on one side of the third gear, a second motor connected to the bottom of the fourth gear through a second rotating shaft, and the second motor being fixedly installed through the inner cavity of one side of the lower support plate.

[0021] Through the above technical solution, the driving structure achieves a stable connection and position-driving positioning effect for the V-shaped wide plate and V-shaped narrow plate.

[0022] Furthermore, limit plates are fixedly installed on both the upper and lower end faces of the rotating rod, and both limit plates are designed with a circular plate structure.

[0023] Through the above technical solution, the limiting plate achieves the limiting function of the two ends of the rotating rod 7528.

[0038] Example:

[0039] This application discloses an integrated tool for cable outer layer circumferential cutting and chamfering. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a main rotating drum 1, with fixed drums 2 slidingly contacting both sides of the main rotating drum 1. A U-shaped seat 3 is fixedly installed at the connection of the bottom outer walls of the two fixed drums 2, and the U-shaped seat 3 is located on the outer side of the bottom of the main rotating drum 1. A first gear 4 is fixedly sleeved on the outer wall of the middle part of the main rotating drum 1. A second gear 5 meshes with the bottom end of the first gear 4. A first motor 6 is connected to one end face of the second gear 5 through a first rotating shaft. The first motor 6 is fixedly installed through one side of the inner cavity of the upper end of the U-shaped seat 3. A ring cutting tool 7 and a chamfering tool 8 are respectively arranged axially symmetrically inside the main rotating drum 1. A first cylinder 9 and a second cylinder 10 are fixedly connected to the opposite ends of the ring cutting tool 7 and the chamfering tool 8. The non-driving ends of the opposite sides of the first cylinder 9 and the second cylinder 10 are fixedly installed on the inner side wall of the main rotating drum 1. A side cylinder 11 is provided on the opposite side of the two fixed drums 2, and a positioning component 12 is provided on the two side cylinders 11.

[0040] Two fixed cylinders 2 each have a circular groove 13 on one end face facing each other. Multiple limiting shafts 14 are slidably sleeved on the inner wall of each side of the groove 13. The multiple limiting shafts 14 are fixedly installed on both ends of the main rotating cylinder 1 in a circumferential manner. A base plate 19 is fixedly connected to the bottom of the U-shaped seat 3. Mounting holes are opened through the four corners of the base plate 19. A control panel 20 is fixedly installed on the middle of one side of the top of the base plate 19.

[0041] The inner and outer diameters of the two side cylinders 11 are the same as those of the main rotating cylinder 1 and the fixed cylinder 2. The left side cylinder 11 is fixedly connected to the left fixed cylinder 2, while there is a gap between the right side cylinder 11 and the right fixed cylinder 2. Four through holes 15 are evenly opened on the circumference of the right side cylinder 11. A sliding rod 16 is slidably connected to the inner wall of each through hole 15.

A drive cylinder 18 is fixedly connected to one side wall of the bottom end of the extension plate 17.

[0042] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 The positioning component 12 includes a V-shaped wide plate 121 located inside the side cylinder 11. Both ends of the middle section of the V-shaped wide plate 121 have notches 122. A V-shaped narrow plate 123 is fitted onto the middle section of the V-shaped wide plate 121 without contact with the notches 122. The V-shaped narrow plate 123 and the V-shaped wide plate 121 are axially symmetrically distributed on the upper and lower sides inside the side cylinder 11. A driving structure is provided at the outer ends of the middle sections of the V-shaped narrow plate 123 and the V-shaped wide plate 121. With the relative arrangement and cooperation of the V-shaped narrow plate 121 and the V-shaped narrow plate 123, the cable to be processed is stably supported and clamped and positioned, while achieving effective applicability to cables of different diameters. The inner walls of the V-shaped wide plate 121 and the V-shaped narrow plate 123 are fixedly installed with anti-slip rubber pads. The anti-slip rubber pads can effectively improve the anti-slip contact effect with the outer surface of the cable and effectively ensure the stability of the stripping operation after the outer insulation layer of the cable is circumferentially cut.

[0043] The driving structure includes a rotating rod 124 located on one side of the side cylinder 11. Threaded grooves are provided on the outer walls of both sides of the rotating rod 124, and connecting arms 125 are screwed onto the outer walls of both sides of the rotating rod 124 through these threaded grooves. Connecting rods 126 are fixedly connected to the sides of the two connecting arms 125 away from the rotating rod 124. Both connecting rods 126 are slidably sleeved into the inner cavity of the outer end of the side cylinder 11, and one end of each connecting rod 126 is fixedly connected to the outer surface of the middle portion of the V-shaped wide plate 121 and the V-shaped narrow plate 123, respectively. I-shaped shafts 127 are fixedly sleeved on the outer walls of both sides of the middle portion of the rotating rod 124. The outer wall of the middle part of the shaft 127 is rotatably sleeved with a support plate 128, and the two support plates 128 are fixedly installed on the outer surface of the side cylinder 11. The drive assembly also includes a third gear 129 fixedly sleeved on the outer wall of the middle part of the rotating rod 124. A fourth gear 1210 is meshed on one side of the third gear 129. The bottom of the fourth gear 1210 is connected to a second motor 1211 through a second rotating shaft. The second motor 1211 is fixedly installed in the inner cavity of one side of the lower support plate 128. Limiting discs are fixedly installed on both the upper and lower end faces of the rotating rod 124, and both limiting discs are designed as circular plate structures.

[0044] The control panel 20 is electrically connected to and controls the first motor 6, the first cylinder 9, the second cylinder 10, the drive cylinder 18, and the second motor 1211 via wires. The connection and control functions of the control panel 20 can be implemented by programming, which is existing technology and will not be elaborated on here.

[0045] The implementation principle of this application embodiment is as follows: Before use, the whole is in a complete assembly state. The mounting holes at the four corners of the base plate 19 are used to realize the positioning and assembly of the whole on the receiving plane. When in use, the end of the cable to be processed is inserted from left to right through the inside of the left side cylinder 11 and out through the inside of the right side cylinder 11. Under the control of the second motor 1211, the meshing state of the fourth gear 1210 and the third gear 129, and the movable receiving and limiting state of the two support plates 128 on the I-shaped shaft 127 and the rotating rod 124, indirectly realize the rotation of the rotating rod 124. Under the relative or opposite movement of the two connecting arms 125, the relative movement between the V-shaped wide plate 121 and the V-shaped narrow plate 123 is realized, thereby realizing the stable receiving and clamping of the cable near its processing end.

[0046] While controlling the start of the first cylinder 9, the cutting head of the circumferential cutting tool 7 is brought into contact with the outer surface of the cable. The feed distance of the first cylinder 9 is set according to the pre-measured thickness of the outer sheath of the cable being processed. At the same time, the first motor 6 is started, and the meshing state of the second gear 5 and the first gear 4 causes the main drum 1 and its upper structure to rotate. This, in conjunction with the first cylinder 9, pushes the circumferential cutting tool 7 to feed, thereby realizing the circumferential cutting operation on the outer layer of the cable insulation. When the main drum 1 is passively rotated, the multiple limiting shafts 14 on its two end faces respectively perform a bearing-type sliding limiting function on the inner wall of the groove 13 on both sides.

[0047] After the outer layer of the cable is circumcised, the first cylinder 9 is used to reset the circumcising cutter 7. Then, the starting drive cylinder 18 is controlled to push the extension plate 17, which indirectly realizes the horizontal pushing motion of the right side cylinder 11 and its upper structure. At the same time, it drives the cable processing end held inside to move synchronously, thus realizing the stripping action of the outer insulation layer of the cable processing end after circumcising. This exposes the inner core near the circumcised position. When the right side cylinder 11 is passively displaced, it slides through each through hole 15 on the outer wall of each slide rod 16. Then, the second cylinder 10 is controlled to drive the chamfering cutter 8. With the passive rotation of the main rotating cylinder 1, the chamfering trimming work of the circumcised position of the cable insulation layer is realized. The chamfering trimming process continues until the end of the chamfering cutter 8 touches the exposed outer surface of the core.

[0048] The device can periodically clean the cable insulation dander remaining inside the main rotating drum 1, the two fixed drums 2, and the side drum 11 by bringing it close to the whole unit with a device such as a hair dryer.

[0049] 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.
