Description

Technical Field

[0001] This invention relates to the field of cable sheath stripping technology, specifically a cable sheath stripping device. Background Technology

[0002] The outer surface of the metal core of a cable is covered with a thick insulating sheath made of rubber, which has a certain degree of elastic deformation and can follow the slight bending of the metal core. Cables are widely used to transmit electricity from power plants to cities, industrial areas, and residential areas. They carry high voltage and high current, transmitting electricity to various facilities such as residential and commercial buildings, factories, and public facilities. The thickness of the cable core varies depending on the amount of electricity to be transmitted.

[0003] The installation of cables or the recycling of scrap cables both require the removal of the cable insulation sheath. Since the thickness of the cable core varies, it is difficult for the cable stripper to fit tightly against the thinner cable. At the same time, the thickness of the insulation sheath covering the outer surface of cables of different thicknesses is also different. If the stripper cuts too deep, it can easily scratch the cable core. As a result, the existing cable sheath removal devices can only remove the sheath of cables of a fixed type.

[0004] The present invention aims to solve the technical problems existing in the prior art, and to this end, a cable sheath stripping device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cable sheath stripping device to solve the problems mentioned in the background art.

[0011] As a further aspect of the present invention: the clamping device includes a mounting frame, a connecting rod fixedly connected to one side of the mounting frame, the other end of the connecting rod extending into the second connecting groove and horizontally slidingly connected to the moving plate, and a rotating rod rotatably connected to the mounting frame, with two rotating blocks fixedly connected to the cylindrical surface of the rotating rod.

[0012] As a further embodiment of the present invention: the adjusting device includes a rotating cylinder, which is rotatably connected to the support frame. The rotating cylinder passes through a through groove, and a second sliding groove is provided on the cylindrical surface of the rotating cylinder. A driven gear is provided on the cylindrical surface of the rotating cylinder, and the driven gear meshes with a second rack. A guide rail is used to limit the driven gear. A second slider is fixedly connected to the inner surface of the driven gear. The second slider is located in the second sliding groove and slides in contact with the rotating cylinder. A first sliding groove is provided on the inner surface of the rotating cylinder, and the rotating cylinder slides in contact with the cable stripping assembly through the first sliding groove.

[0013] As a further aspect of the present invention: the cable stripping assembly includes a lead screw, one end of which extends into a rotating drum, and a first slider is fixedly connected to the cylindrical surface of the lead screw.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By rotating the bidirectional threaded rod, the two transmission mechanisms are driven to move closer together, and the two transmission mechanisms drive the two clamping devices to move respectively, thereby fixing the cable and preventing the cable from moving during the stripping process, which would cause the stripping depth to change.

[0016] 2. The drive mechanism drives the transmission mechanism to move horizontally, which in turn drives the adjustment device to rotate. The adjustment device then drives the cable stripping assembly to rotate. Since the cable stripping assembly is threadedly connected to the clamping device, the cable stripping assembly moves as it rotates, thus allowing the stripping depth to be adjusted according to the cable thickness, avoiding damage to the cable core.

[0027] Please see Figure 1-4 In this embodiment of the invention, a cable sheath stripping device includes a support frame body 1. Two transmission mechanisms 4 are arranged inside one side of the support frame body 1. The two transmission mechanisms 4 are located on both sides of the support frame body 1 and are threadedly connected to the support frame body 1. Adjustment devices 5 are rotatably connected to both sides of the support frame body 1. The two adjustment devices 5 pass through the two transmission mechanisms 4 and mesh with the transmission mechanisms 4. Clamping devices 6 are slidably connected to one side of each of the two transmission mechanisms 4. The transmission mechanisms 4 are used to drive the clamping devices 6 to move, and the clamping devices 6 clamp the cable. Cable stripping components 2 are slidably connected to each of the two adjustment devices 5. The adjustment devices 5 are used to drive the cable stripping components 2 to rotate. The other ends of the two cable stripping components 2 extend into the two clamping devices 6 respectively. The cable stripping components 2 are threadedly connected to the clamping devices 6 and are used to adjust the cable stripping depth.

[0028] The main body 1 of the support frame is rotatably connected to a drive mechanism 3. The drive mechanism 3 meshes with the transmission mechanism 4. The drive mechanism 3 is used to drive the transmission mechanism 4 to move, and the transmission mechanism 4 drives the adjustment device 5 to rotate.

[0029] Please see Figure 1-4 The main body 1 of the support frame includes a support frame 101. A motor 104 is provided on one side of the support frame 101. A rotating shaft 102 is fixedly connected to the other end of the motor 104. A conveying roller 103 is fixedly connected to the cylindrical surface of the rotating shaft 102. A scale 105 is provided on one side of the support frame 101. A rotating handle 107 is rotatably connected to one side of the support frame 101. A bidirectional threaded rod 106 is fixedly connected to one side of the rotating handle 107. The bidirectional threaded rod 106 passes through the transmission mechanism 4 and is threadedly connected to the transmission mechanism 4.

[0030] Please see Figure 1-4 The transmission mechanism 4 includes a movable plate 401 with a first connecting groove 402. A connecting block 408 is disposed inside the movable plate 401, and the connecting block 408 is horizontally slidably connected to the first connecting groove 402 via the movable plate 401. A bidirectional threaded rod 106 passes through the connecting block 408 and is threadedly connected to the connecting block 408. A first rack 403 is disposed on one side of the movable plate 401, and a guide rail 407 is fixedly connected to one side of the first rack 403. The movable plate 401 slides in contact with the first rack 403 via the guide rail 407. The first rack 403 meshes with the drive mechanism 3. A through groove 404 is disposed on one side of the movable plate 401, and a plurality of second racks 405 are fixedly connected to the movable plate 401. The second racks 405 are located in the through groove 404 and mesh with the adjusting device 5. A pin block 406 is provided on one side of the movable plate 401. The pin block 406 slides vertically with the movable plate 401. The other end of the pin block 406 extends into the through groove 404. A second connecting groove 409 is provided on one side of the movable plate 401. The movable plate 401 is horizontally slidably connected to the clamping device 6 through the second connecting groove 409. The drive shaft 303 is rotated by the handle 302, and the drive shaft 303 drives the drive gear 301 to rotate. Since the drive gear 301 meshes with the first rack 403, the drive gear 301 drives the first rack 403 to move. The first rack 403 drives the movable plate 401 to move through the guide rail 407. The movable plate 401 drives the second rack 405 to move. Since the second rack 405 meshes with the driven gear 505, the second rack 405 drives the driven gear 505 to rotate.

[0031] Please see Figure 1-4The clamping device 6 includes a mounting frame 601. A connecting rod 602 is fixedly connected to one side of the mounting frame 601. The other end of the connecting rod 602 extends into the second connecting groove 409 and is horizontally slidably connected to the moving plate 401. A rotating rod 603 is rotatably connected to the mounting frame 601. Two rotating blocks 604 are fixedly connected to the cylindrical surface of the rotating rod 603. By rotating the bidirectional threaded rod 106 through the rotating handle 107, the bidirectional threaded rod 106 drives the two connecting blocks 408 to move closer together. That is, the two connecting blocks 408 drive the moving plate 401 to move along the guide rail 407 through the first connecting groove 402. At the same time, the two moving plates 401 move through the second connecting groove 409 and the connecting rod 602 respectively. That is, the connecting rod 602 drives the mounting frame 601 to move. The mounting frame 601 drives the rotating blocks 604 to move through the rotating rod 603, so that the rotating blocks 604 clamp and fix the cable.

[0032] Please see Figure 1-4 The adjusting device 5 includes a rotating cylinder 501, which is rotatably connected to the support frame 101. The rotating cylinder 501 passes through a through groove 404. A second sliding groove 503 is provided on the cylindrical surface of the rotating cylinder 501. A driven gear 505 is provided on the cylindrical surface of the rotating cylinder 501. The driven gear 505 meshes with a second rack 405. A guide rail 407 is used to limit the driven gear 505. A second slider 504 is fixedly connected to the inner surface of the driven gear 505. The second slider 504 is located in the second sliding groove 503 and slides in contact with the rotating cylinder 501. A first sliding groove 502 is provided on the inner surface of the rotating cylinder 501. The rotating cylinder 501 slides in contact with the cable stripping assembly 2 through the first sliding groove 502.

[0033] Please see Figure 1-4 The cable stripping assembly 2 includes a lead screw 201. One end of the lead screw 201 extends into a rotating drum 501, and a first slider 202 is fixedly connected to the cylindrical surface of the lead screw 201. The first slider 202 is located in a first groove 502 and slides in contact with the rotating drum 501. The other end of the lead screw 201 extends into a mounting bracket 601 and is threadedly connected to the mounting bracket 601. A connecting plate 203 is rotatably connected to the other end of the lead screw 201. The connecting plate 203 slides horizontally in contact with the mounting bracket 601. A mounting frame 204 is fixedly connected to the other end of the connecting plate 203. 204 is located between two rotating blocks 604. A rotating rod 603 passes through and slides in contact with the mounting frame 204. A stripping blade 205 is fixedly connected to the other end of the mounting frame 204. A driven gear 505 drives a rotating drum 501 to rotate via a second slider 504 and a second groove 503. The rotating drum 501 drives a lead screw 201 to rotate via a first groove 502 and a first slider 202. Since the lead screw 201 is threadedly connected to the mounting bracket 601, it moves when it rotates, thus moving the mounting frame 204. The mounting frame 204 then moves 206, allowing the stripping depth to be adjusted according to the cable thickness.

[0034] Please see Figure 1-4 The drive mechanism 3 includes a drive shaft 303, which is rotatably connected to the support frame 101. A handle 302 is fixedly connected to one end of the drive shaft 303. An index 304 is fixedly connected to the cylindrical surface of the drive shaft 303. The index 304 slides in contact with the dial 105. A drive gear 301 is fixedly connected to the cylindrical surface of the drive gear 301. The drive gear 301 meshes with the first rack 403.

[0035] The working principle of this invention is as follows: Rotating the bidirectional threaded rod 106 via the handle 107 causes the two connecting blocks 408 to move closer together. Specifically, the two connecting blocks 408, through the first connecting groove 402, drive the moving plate 401 to move along the guide rail 407. Simultaneously, the two moving plates 401, through the second connecting groove 409, move via the connecting rod 602. This causes the connecting rod 602 to move the mounting bracket 601. The mounting bracket 601, through the rotating rod 603, drives the rotating block 604 to move, thereby clamping and fixing the cable with the rotating block 604, preventing movement of the cable during stripping and thus avoiding changes in the stripping depth. Simultaneously, the rotating rod 603 is rotatably connected to the mounting bracket 601, allowing the rotating block 604 to rotate, preventing cable movement. The handle 302 is rotated... The drive shaft 303 drives the drive gear 301 to rotate. Since the drive gear 301 meshes with the first rack 403, it moves the first rack 403. The first rack 403 then moves the moving plate 401 via the guide rail 407. The moving plate 401 moves the second rack 405. Since the second rack 405 meshes with the driven gear 505, it rotates the driven gear 505. The driven gear 505 then rotates the rotating drum 501 via the second slider 504 and the second slide groove 503. The rotating drum 501 rotates the lead screw 201 via the first slide groove 502 and the first slider 202. Since the lead screw 201 is threadedly connected to the mounting frame 601, its rotation causes movement, which in turn moves the mounting frame 204. The mounting frame 204 then moves the mounting bracket 206, allowing the stripping depth to be adjusted according to the cable thickness, thus preventing damage to the cable core.
