Description

Technical Field

[0001] This invention relates to the field of cable stripping, and more particularly to a cable stripping device for electrical equipment maintenance. Background Technology

[0002] A cable is a conductor used to transmit electrical energy, signals, and other information. It typically consists of multiple insulated conductors encased in a robust protective layer. Cables are more complex in structure than wires, often having two or more layers of insulation and potentially containing multiple cores.

[0003] When splicing cables, the sheath at the end needs to be cut off. This operation is usually done manually, that is, using pliers to cut open the outer sheath and then pulling it off. However, because it is a manual operation, the force used during cutting cannot be precisely controlled, which can easily damage the core and is quite laborious.

[0004] Therefore, it is necessary to provide a new cable stripping device for electrical equipment maintenance to solve the above-mentioned technical problems. Summary of the Invention

A mounting ring plate, concentric with the second hole, is rotatably arranged on one side of the third mounting frame. A set of cutting components and three sets of rollers are fixed on one side of the mounting ring plate in a ring shape. One set of rollers and the cutting components are symmetrically arranged and in the same vertical plane to counteract the force exerted on the cable by the cutting components during the cutting process. The remaining two sets of rollers are symmetrically arranged and not in the same vertical plane as the cutting components. They are used to symmetrically clamp the cable and create dense gaps between the cable sheath and the core through roller pressing.

A sleeve rod is also fixed at one end of the clamping block, and a rubber block for clamping the cable is sleeved and fixed through the sleeve rod.

[0008] Preferably, a concentric transmission ring plate is also fixed to one side of the adjusting ring plate, and the outer circumferential wall of the transmission ring plate has a section of teeth; A second mounting bracket is also fixed to one side of the first mounting bracket. A first motor is fixed on the second mounting bracket. A first gear is fixed to the output end of the first motor. The first gear meshes with the teeth of the first motor to drive the adjusting ring plate to rotate circumferentially.

[0009] Preferably, a second ring plate concentrically arranged with the second hole is fixed on one side of the third mounting bracket, and an external toothed ring is rotatably connected to the outer circumferential wall of the second ring plate, and a mounting ring plate is fixed on the other side of the external toothed ring; A second motor is also fixed on one side of the third mounting bracket. A second gear is fixed to the output end of the second motor. The second gear meshes with the external gear ring to drive the mounting ring plate to rotate circumferentially.

[0010] Preferably, the cutting component includes a first positioning foot plate, which is fixed to the mounting ring plate. A first cylinder is installed on one side of the first positioning foot plate. The output end of the first cylinder is radially along the mounting ring plate and is fixed with a first positioning bracket. A circumferential cutting blade is fixed on the first positioning bracket for cutting the outer sheath of the cable.

[0011] Preferably, the roller pressing unit includes a second positioning foot plate, which is fixed to the mounting ring plate. A second cylinder is installed on one side of the second positioning foot plate. The output end of the second cylinder is radially along the mounting ring plate and is fixed with a second positioning bracket. The other end of the second positioning bracket is fixed with a bearing seat through a right-angle bracket. Two rollers are rotatably connected to the bearing seat. In the two roller pressing parts that are not on the same horizontal plane as the cutting part, the second positioning foot plate is fixed to the mounting ring plate by an auxiliary bracket.

[0012] Preferably, a single helical screw arranged along the length direction is mounted on the base frame via a foot bracket, and a light rod parallel to the single helical screw is also fixed thereon, as well as a third motor that drives the single helical screw to rotate. A transmission seat is connected to the single helical screw, and the fourth mounting bracket is fixed to the transmission seat.

[0013] Preferably, a strip is fixed to the outer circumference of the circular plate, and an extension frame arranged radially along the circular plate is fixed to the strip. A fourth motor is also fixed on the fourth mounting bracket. A transmission plate is vertically fixed to the output end of the fourth motor.

[0015] Compared with related technologies, the cable stripping device for electrical equipment maintenance provided by the present invention has the following advantages: 1. The second motor drives the mounting ring plate to rotate in a circular motion, which in turn drives the cutting parts to rotate. After the circumferential cutting blade contacts the cable sheath, the circumferential cutting operation of the cable is realized, which has higher cutting efficiency and cutting accuracy. 2. When the tube sheet is installed and rotated, it can also drive the roller pressing parts to rotate together. The rollers are used to perform roller pressing on the cable sheath, so that a dense gap is created between the sheath and the core, making it easier to remove the cut sheath later. 3. The circular plate can reciprocate in a circular motion. Therefore, after the cable sheath is held by the clamping device, the sheath can be twisted repeatedly and pulled at the same time, which makes it easier to remove the sheath and will not damage the core due to excessive torque.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 14 The present invention provides a cable stripping device for electrical equipment maintenance. The cable stripping device for electrical equipment maintenance includes a base frame 1, a cutting unit 2 and a stripping unit 3 installed on the base frame 1, and a waste discharge hopper 11 located between the cutting unit 2 and the stripping unit 3 on the base frame 1. It should be noted that in this device, the cutting unit 2 is used to perform automated circumferential cutting of the outer sheath of the cable, and after cutting, the sheath is removed by the stripping unit 3. Compared with traditional manual operation, it has higher processing accuracy and processing efficiency.

[0021] The cutting unit 2 includes a fixing mechanism and a cutting mechanism. Please see Figures 3 to 5The fixing mechanism includes a first mounting frame 21, which has holes 22 for passing cables through it. The first mounting frame 21 also has multiple strip-shaped slides 23 arranged in a ring around the center of the holes 22. The length of the strip-shaped slides 23 is along the radial direction of the holes 22. A first ring plate 28, which is concentric with the holes 22, is also fixed to one side of the first mounting frame 21. An adjusting ring plate 29 is rotatably connected to the first ring plate 28. The adjusting ring plate 29 has arc-shaped grooves 210 that correspond to the number and position of the strip-shaped slides 23. A concentric transmission ring plate 211 is also fixed on one side of the adjusting ring plate 29. A section of teeth 212 is provided on the outer circumference of the transmission ring plate 211. A second mounting bracket 213 is also fixed on one side of the first mounting bracket 21. A first motor 214 is fixed on the second mounting bracket 213. A first gear 215 is fixed at the output end of the first motor 214. The first gear 215 and the teeth 212 mesh and drive the adjusting ring plate 29 to rotate circumferentially. Multiple clamping blocks 24 are movably mounted on one side of the first mounting bracket 21 with hole 22 as the center. A transmission pin 25 is vertically fixed on one side of the clamping block 24. The transmission pin 25 passes through the strip slide 23 and extends into the arc-shaped slide groove 210. A sleeve rod 26 is also fixed at one end of the clamping block 24, and a rubber block 27 for clamping the cable is sleeved and fixed through the sleeve rod 26.

[0022] It should be noted that the cable needs to be fixed before the circumferential cutting operation to prevent the cable from swinging or shaking during the cutting process, thereby ensuring the cutting accuracy. During the fixing operation, the cable is passed through the first mounting bracket 21 and the third mounting bracket 216 along the first hole 22 and the second hole 217. Then, the first motor 214 drives the first gear 215 to rotate, thereby driving the transmission ring plate 211 to rotate, and then driving the adjusting ring plate 29 to rotate. The transmission pin 25 on the clamping block 24 extends into the arc-shaped slide groove 210. Therefore, when the adjusting ring plate 29 rotates, it can exert a force on the transmission pin 25. At the same time, the transmission pin 25 is limited by the strip slide 23, realizing the synchronous movement of multiple clamping blocks 24 along the radial direction of the first hole 22. There is a rubber block 27 at the other end of the clamping block 24, which is used to achieve stable clamping of the cable. The rubber block 27 can be directly fitted onto the sleeve rod 26, making it easy to disassemble and replace.

[0023] Please see Figures 6 to 9The cutting mechanism includes a third mounting frame 216, which is fixed to the first mounting frame 21. The third mounting frame 216 has a second hole 217 corresponding to the first hole 22. A second ring plate 218, which is concentrically arranged with the second hole 217, is fixed on one side of the third mounting frame 216. An external gear ring 219 is rotatably connected to the outer circumference of the second ring plate 218. A mounting ring plate 220 is fixed on the other side of the external gear ring 219. A second motor 221 is also fixed on one side of the third mounting frame 216. A second gear 222, which is concentrically arranged, is fixed at the output end of the second motor 221. The second gear 222 and the external gear ring 219 mesh and drive each other. A set of cutting parts and three sets of roller pressing parts are fixed on one side of the mounting ring plate 220. One set of roller pressing parts and cutting parts are symmetrically arranged and located in the same vertical plane. The cutting component includes a first positioning foot plate 223, which is fixed on the mounting ring plate 220. A first cylinder 224 is installed on one side of the first positioning foot plate 223. The output end of the first cylinder 224 is along the radial direction of the mounting ring plate 220 and is fixed with a first positioning bracket 225. A ring cutting blade 226 is fixed on the first positioning bracket 225. The rolling unit includes a second positioning foot plate 227, which is fixed on the mounting ring plate 220. A second cylinder 228 is installed on one side of the second positioning foot plate 227. The output end of the second cylinder 228 is along the radial direction of the mounting ring plate 220 and is fixed with a second positioning bracket 229. The other end of the second positioning bracket 229 is fixed with a bearing seat 231 through a right angle bracket 230. Two rollers 232 are rotatably connected on the bearing seat 231. Among the two roller pressing parts that are not on the same horizontal plane as the cutting part, the second positioning foot plate 227 is fixed to the mounting ring plate 220 by the auxiliary bracket 233.

[0024] It should be noted that during the cable circumferential cutting operation, the second motor 221 drives the second gear 222 to rotate, which in turn drives the outer gear ring 219 and the mounting ring plate 220 to rotate. Then the cutting component and the roller component move synchronously, so that the circumferential cutting blade 226 and the roller 232 both contact the cable. During the circumferential rotation, the circumferential cutting blade 226 performs circumferential cutting on the cable sheath. At the same time, a set of roller components symmetrical to the cutting component can support the cable to counteract the pressure exerted by the circumferential cutting blade 226 on the cable and improve the cutting effect of the circumferential cutting blade 226 on the cable. The remaining two sets of rollers are symmetrically arranged, and their contact points with the cable are the positions where the cable will be removed. Therefore, the pressure they exert on the cable can be relatively increased, and the cable is circumferentially rolled during the circumferential rotation. During the rolling process, a dense gap is created between the cable sheath and the core, making it easier to remove the sheath later.

[0025] For peeling unit 3; Please see Figures 10 to 12 It includes a single helical screw 31 mounted on a base frame 1 via a bracket, and a smooth rod 32 parallel to the single helical screw 31. A third motor 33 that drives the single helical screw 31 to rotate is mounted on the base frame 1. A transmission seat 34 is connected to the single helical screw 31. A fourth mounting bracket 35 is fixed on the transmission seat 34. A circular plate 36 is rotatably connected to the fourth mounting bracket 35. A strip plate 37 is also fixed to the outer circumference of the circular plate 36. An extension bracket 38 arranged radially along the circular plate 36 is fixed on the strip plate 37. A fourth motor 39 is also fixed on the fourth mounting bracket 35. A transmission plate 310 is vertically fixed to the output end of the fourth motor 39. A connecting pin 311 is fixed to the other end of the transmission plate 310. The connecting pin 311 passes through the extension bracket 38.

[0026] It should be noted that the third motor 33 can drive the single helical screw 31 to rotate, which is used to drive the transmission seat 34 and the fourth mounting bracket 35 to move, thereby changing the distance between the peeling unit 3 and the cutting unit 2, realizing the pulling of the skin layer and the removal of the skin layer. The fourth motor 39 can drive the transmission plate 310 to rotate in a circle. The connecting pin 311 at the other end of the transmission plate 310 is slidably connected to the extension frame 38. Therefore, during the movement of the connecting pin 311 in the vertical plane, the circular plate 36 can be driven to reciprocate through the extension frame 38.

[0027] Please see Figure 13 and Figure 14 A clamping component is also installed on the circular plate 36. The clamping component includes a fifth motor 312, which is concentrically fixed on the circular plate 36. A worm gear 313 is fixed at the output end of the fifth motor 312. On the other side of the circular plate 36, a plurality of ring-shaped third positioning brackets 314 are fixed. A first shaft and a second shaft are rotatably connected to the third positioning brackets 314. A worm wheel 315 that meshes with the worm 313 is fixed on the first shaft. An active transmission arm 316 is also fixed on the first shaft. An auxiliary positioning arm 317 that is parallel to the active transmission arm 316 is fixed on the second shaft. A positioning frame 318 is rotatably connected to the other end of the active transmission arm 316 and the auxiliary positioning arm 317. A rubber plate 319 is fixed on the positioning frame 318.

[0028] It should be noted that when fixing cables, the clamps can also directly clamp the cables, further enhancing the cable restraint without affecting the cable circumferential cutting operation. The fifth motor 312 can directly drive the worm 313 to rotate, and then drive the active transmission arm 316 to rotate through the worm wheel 315. In conjunction with the positioning function of the auxiliary positioning arm 317, the positioning frame 318 will generate relative displacement to achieve clamping of the cable. After achieving stable clamping, the sheath can be removed after the circumferential cutting operation is completed. Because the circular plate 36 can rotate in a circular reciprocating motion, the entire clamping component will also rotate. During the process of pulling the skin, it can also continuously twist the skin, so the peeling operation will be faster and will not damage the core. After the outer layer is removed, it can be directly placed into the waste discharge hopper 11, which will then remove the outer layer for convenient subsequent centralized processing.

[0029] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
