Description

Technical Field

[0001] This invention relates to the field of wire stripper technology, specifically a graded cable stripper. Background Technology

[0002] A cable stripper is a type of cable outer semiconductor layer stripper, specifically designed to strip the insulation layer outside the core wire to be connected.

[0003] Currently, the common method of using cable strippers to snap and press out the outer insulation layer of cables requires manual intervention based on feel. Since the thickness of the outer insulation layer varies among different cables, excessive manual pressure can cause the core wire to break. Additionally, due to the columnar structure of the cable, when the cable stripper cannot cut the insulation layer to the same depth, uneven ends will appear. These uneven insulation layer ends will compress the core wire, eventually leading to its breakage.

[0004] The key technical challenge that this invention aims to overcome is how to improve the accuracy of cutting and peeling the columnar insulation layer while ensuring the neatness of the cut. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted in this invention is as follows: A graded cable stripper includes a clamping mechanism, a cable straightening mechanism, and a cable ring-cutting mechanism. The clamping mechanism includes a first and second ring clamped onto the cable; two measuring rulers installed on both sides of the first ring and inserted into the external clamping grooves of the second ring; two main pressure components and two auxiliary pressure components respectively connected to the first and second rings; two pressure-increasing sleeves respectively assembled into the top holes of the first and second rings; two arc strips installed on both sides of the pressure-increasing sleeves; and two pull rods respectively connected to the bottom ends of the two arc strips. The cable straightening mechanism includes a main washer installed at one end of the first ring; a beam frame installed on the main washer; an auxiliary washer connected to the outer end of the beam frame; a cable tie end tube installed on the auxiliary washer; and a screw... The cable circumferential cutting mechanism includes two combined positioning components bolted to the beam frame, a motor installed within the two combined positioning components, a buckle plate bolted to the bottom of the main washer, and two screw rods installed at the end of the cable tie tube away from the secondary washer. The cable circumferential cutting mechanism includes a guide washer movably installed in the inner groove of the main washer, a fixed rotating wheel installed outside the guide washer using a U-shaped pull rod, a cutting end connected to the inside of the guide washer using a spring, two main sliders installed at the bottom of the beam frame, a first slip ring and a second slip ring movably installed on the two main sliders respectively, a screw cylinder threaded to the first slip ring, a crossbar installed inside the screw cylinder and penetrating into the first and second slip rings, and a sub-slider installed at the end of the crossbar away from the guide washer.

[0007] In a preferred embodiment, the present invention can be further configured such that: two buckles are installed on the sidewalls of the inner cavities of the first and second ring buckles, and the buckles are adapted to constrain the middle of the arc strip; and vertical holes are provided at the bottom of both the first and second ring buckles.

[0008] By adopting the above technical solution, the two buckles installed on the inner walls of the first and second rings respectively constrain and guide the two arc strips. As the inner screw of the main pressure component descends and drives the pressure-boosting sleeve and the two arc strips to move downward, the two arc strips can push the pull rod and the auxiliary pressure component in the opposite direction to tighten and clamp the cable, thereby ensuring that the cable located between the first and second rings is taut.

[0009] In a preferred embodiment, the present invention can be further configured such that: the main pressure component is composed of a screw and an arc-shaped main pad, and the secondary pressure component is composed of an end post and an arc-shaped secondary pad, wherein the arc-shaped main pad and the arc-shaped secondary pad are symmetrically distributed on the outside of the cable in a circular ring structure.

[0010] By adopting the above technical solution, when the screw inside the main pressure component descends clockwise, the arc-shaped main pad and arc-shaped secondary pad inside the main pressure component and the secondary pressure component can simultaneously clamp the outside of the cable. The cable located in the first ring buckle after the two combinations and inside the main pressure component can be in a taut state to prevent the cable from shaking.

[0011] In a preferred embodiment, the present invention can be further configured such that: the inner wall of the secondary pad ring is provided with an annular groove constraining the sub-slider; the wire harness end tube is generally T-shaped; two pads are installed at the end of the wire harness end tube away from the secondary pad ring; and the pads are provided with screw holes constraining the screw rod.

[0012] By adopting the above technical solution, the sub-slider is movably installed in the annular groove on the inner wall of the secondary pad ring, and the two main sliders installed at the bottom of the beam frame respectively position and constrain the first slip ring and the second slip ring. At this time, the combined crossbar, the first slip ring and the second slip ring can rotate as a whole with the guide washer. At this time, the cable located between the main pad ring and the secondary pad ring can be circumcised by the cutting end at a constant speed.

[0013] In a preferred embodiment, the present invention may be further configured such that the positioning element consists of a Y-shaped bracket, a clamping strip, and bolts.

[0014] By adopting the above technical solution, the clamping bar and the Y-shaped bracket are fixed with bolts. At this time, the motor located between the Y-shaped bracket and the clamping bar can be fixed. When the fixed motor starts and rotates, the track linked on the external shaft of the motor can drive the fixed wheel to rotate stably.

[0015] In a preferred embodiment, the present invention may be further configured such that: the end of the guide washer away from the main washer ring has an inclined slot, and the bottom end of the cut end extends into the inner cavity of the guide washer.

[0016] By adopting the above technical solution, the inner end of the guide washer is inserted into the groove of the main washer. When the crossbar is inserted into the inner slot of the guide washer, the rotating fixed wheel and the guide washer can drive the squeezed and stretched cutting end to perform precise deep circumferential stripping of the outer insulation layer of the cable.

[0017] In a preferred embodiment, the present invention can be further configured such that both the first slip ring and the second slip ring have annular grooves on their outer surfaces.

[0018] By adopting the above technical solution, the first slip ring and the second slip ring are positioned and constrained by two main sliders installed at the bottom of the beam frame. At this time, the first slip ring and the second slip ring located outside the cable can provide sufficient stability for the rotating guide washer and the fixed wheel.

[0019] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention involves installing a cutting end head at one end of the first ring buckle to guide the circumferential cutting of the cable's outer insulation layer, and setting a motor at the top of the beam frame. When the cable is taut, the user can adjust the screw to push the crossbar into the slot inside the guide washer. As the crossbar presses against the cutting end head, the cutting end head extends into the cable insulation layer. As the motor runs, the track connected to the external shaft drives the fixed rotating wheel and the combined guide washer to perform circumferential cutting on the cable's exterior. At this time, the device can perform precise thickness circumferential cutting on the cable's outer insulation layer, thereby ensuring that the cable's outer insulation layer can be circumferentially cut to a standardized degree.

[0020] 2. The present invention installs a first ring buckle at one end of the main pad ring and sets a second ring buckle on the side of the first ring buckle away from the main pad ring. At this time, the two main pressure members and two auxiliary pressure members connected in the first ring buckle and the second ring buckle respectively can be clamped to the outside of the cable as the screw applies pressure. At this time, the cable to be ring cut can remain stable during the ring cutting, avoiding the problem of cable shaking and twisting when the cutting end rotates. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a graded cable stripper provided by the present invention. Example 1:

[0026] Combination Figures 1-12 As shown, the present invention provides a graded cable stripper, including a clamping mechanism 100, a conduit straightening mechanism 200, and a cable circumferential cutting mechanism 300. The conduit straightening mechanism 200 is mounted on the clamping mechanism 100, and the cable circumferential cutting mechanism 300 is mounted inside the conduit straightening mechanism 200.

[0027] The clamping mechanism 100 includes a first ring buckle 110, a measuring ruler 120, a second ring buckle 130, a main pressure component 140, a secondary pressure component 150, a pressure-boosting sleeve 160, an arc strip 170, and a pull rod 180. The cable straightening mechanism 200 includes a main washer ring 210, a beam frame 220, a secondary washer ring 230, a cable end tube 240, a positioning component 250, a motor 260, a buckle plate 270, and a screw 280. The cable circumferential cutting mechanism 300 includes a guide washer 310, a main slider 320, a first slip ring 330, a second slip ring 340, a screw barrel 350, a crossbar 360, a sub-slider 370, a fixed rotating wheel 380, and a cutting end 390.

[0028] Specifically, two measuring tapes 120 are respectively installed on both sides of the first ring buckle 110 and inserted into the clamping grooves outside the second ring buckle 130. Two main pressure components 140 and two auxiliary pressure components 150 are respectively connected to the first ring buckle 110 and the second ring buckle 130. Two pressure-boosting sleeves 160 are respectively assembled into the holes at the top of the first ring buckle 110 and the second ring buckle 130. Two arc strips 170 are installed on both sides of the pressure-boosting sleeves 160. Two tie rods 180 are respectively connected to the bottom ends of the two arc strips 170. A main washer ring 210 is installed at one end of the first ring buckle 110. A beam frame 220 is installed on the main washer ring 210. An auxiliary washer ring 230 is connected to the outer end of the beam frame 220. A cable tie end tube 240 is installed on the auxiliary washer ring 230. Two combined positioning components 250 are bolted to the beam frame 220. A motor 260 is installed on the two combined positioning components. Inside the positioning component 250, the buckle plate 270 is bolted to the bottom of the main washer ring 210, two screws 280 are installed on the end of the cable tie tube 240 away from the secondary washer ring 230, the guide washer 310 is movably installed in the groove inside the main washer ring 210, the fixed rotating wheel 380 is installed on the outside of the guide washer 310 by a U-shaped pull rod, the cutting end 390 is connected to the inside of the guide washer 310 by a spring, two main sliders 320 are installed at the bottom of the beam frame 220, the first slip ring 330 and the second slip ring 340 are respectively movably installed on the two main sliders 320, the screw barrel 350 is threaded to the first slip ring 330, the crossbar 360 is installed inside the screw barrel 350 and passes through the inside of the first slip ring 330 and the second slip ring 340, and the sub-slider 370 is installed on the end of the crossbar 360 away from the guide washer 310.

[0029] A second ring 130 is provided on the side of the first ring 110 away from the main pad ring 210. At this time, the two main pressure members 140 and the two auxiliary pressure members 150 connected in the first ring 110 and the second ring 130 respectively can be clamped to the outside of the cable as the screw advances and applies pressure. At this time, the cable to be circumcised can remain stable during circumcising. After the cable is straightened, the user can adjust the screw cylinder 350 to push the crossbar 360 to insert into the slot inside the guide washer 310. As the crossbar 360 squeezes the cutting end 390, the cutting end 390 will extend into the cable insulation layer. With the operation of the motor 260, the track connected to its external shaft can drive the fixed rotating wheel 380 and the combined guide washer 310 to perform circumcising operation on the outside of the cable. At this time, the device can perform circumcising operation on the outer insulation layer of the cable with precise thickness, thereby ensuring that the outer insulation layer of the cable can be circumcised in a standardized manner. Example 2:

[0030] Combination Figures 4-6As shown, based on Embodiment 1, two buckles are installed on the side walls of the inner cavities of the first ring buckle 110 and the second ring buckle 130, and the buckles are adapted to constrain the middle of the arc strip 170. Vertical holes are opened at the bottom of the first ring buckle 110 and the second ring buckle 130. The main pressure component 140 is composed of a screw and an arc-shaped main pad, and the secondary pressure component 150 is composed of an end post and an arc-shaped secondary pad. The arc-shaped main pad and the arc-shaped secondary pad are symmetrically distributed on the outside of the cable in a circular ring structure.

[0031] The two buckles installed on the inner walls of the first ring buckle 110 and the second ring buckle 130 respectively constrain and guide the two arc strips 170. As the screw inside the main pressure member 140 descends and drives the pressure-boosting sleeve 160 and the two arc strips 170 to move downward, the two arc strips 170 can push the pull rod 180 and the auxiliary pressure member 150 to tighten and clamp the cable. This ensures that the cable between the first ring buckle 110 and the second ring buckle 130 is taut. As the screw inside the main pressure member 140 descends clockwise, the arc-shaped main pad and arc-shaped auxiliary pad inside the main pressure member 140 and the auxiliary pressure member 150 can simultaneously clamp the outside of the cable. The cable inside the first ring buckle 110 and the main pressure member 140 after the two combinations can be in a taut state to prevent the cable from shaking. Example 3:

[0032] Combination Figures 7-9 As shown, based on Embodiment 1, the inner wall of the secondary pad ring 230 is provided with an annular groove that constrains the sub-slider 370. The wire harness end tube 240 has an overall T-shaped structure. Two pads are installed at the end of the wire harness end tube 240 away from the secondary pad ring 230, and the pads are provided with screw holes that constrain the screw 280. The positioning component 250 is composed of a Y-shaped bracket, a clamping strip, and bolts.

[0033] By using the sub-slider 370 movably installed in the annular groove on the inner wall of the auxiliary pad ring 230, and cooperating with the two main sliders 320 installed at the bottom of the beam frame 220 to position and constrain the first slip ring 330 and the second slip ring 340 respectively, the combined crossbar 360, the first slip ring 330 and the second slip ring 340 can rotate as a whole with the guide washer 310. The cable located between the main pad ring 210 and the auxiliary pad ring 230 can be circumferentially cut by the cut end 390 at a constant speed, and the clamping strip and the Y-shaped bracket are fixed with bolts. The motor 260 located between the Y-shaped bracket and the clamping strip can be fixed. When the fixed motor 260 starts and rotates, the track linked on the external shaft of the motor 260 can drive the fixed rotating wheel 380 to rotate stably. Example 4:

[0034] Combination Figure 11 and Figure 12As shown, based on Embodiment 1, the guide washer 310 has an inclined slot at one end away from the main washer ring 210, and the bottom end of the cut end 390 penetrates into the inner cavity of the guide washer 310. The outer sides of the first slip ring 330 and the second slip ring 340 are both provided with annular grooves.

[0035] By inserting the inner end of the guide washer 310 into the groove of the main washer 210, when the crossbar 360 is inserted into the inner slot of the guide washer 310, the rotating fixed wheel 380 and the guide washer 310 can drive the squeezed and stretched cutting end 390 to perform precise deep circumferential cutting and peeling of the outer insulation layer of the cable. With the help of the two main sliders 320 installed at the bottom of the beam frame 220, the first slip ring 330 and the second slip ring 340 are positioned and constrained respectively. At this time, the first slip ring 330 and the second slip ring 340 located outside the cable can provide sufficient stability for the rotating guide washer 310 and the fixed wheel 380.

[0036] The working principle and usage process of this invention are as follows: First, a spring is used to connect the cutting end 390 to the slot in the inner wall of the guide washer 310. Then, multiple U-shaped tie rods are used to install the fixed rotating wheel 380 on the outside of the end of the guide washer 310. Next, the inner end of the guide washer 310 is inserted into the annular groove on the inner side of the main washer 210. The main washer 210 and the secondary washer 230 are connected using the beam frame 220. At this time, the two combined positioning parts 250 are bolted to the top of the beam frame 220, and the wire harness end tube 240 is assembled on the outside of the secondary washer 230. Then, the two combined screws 280 are threaded into the inserts on the outside of the wire harness end tube 240. Finally, the two main sliders 320 are installed on the beam frame 220. At the bottom, the two main sliders 320 will movably assemble the first slip ring 330 and the second slip ring 340, while the crossbar 360 will be assembled into the first slip ring 330 by the screw cylinder 350. At this time, the inner end of the crossbar 360 is adapted to extend through to the outside of the second slip ring 340, and the end of the inner end of the crossbar 360 is inserted into the slot on the inner side of the guide washer 310. The sub-slider 370 installed on the crossbar 360 will be movably installed in the annular groove on the inner side of the auxiliary washer 230. Then, the two main pressure members 140 and the two auxiliary pressure members 150 are respectively assembled into the inside of the first ring buckle 110 and the second ring buckle 130. The two measuring scales 120 installed on both sides of the first ring buckle 110 will be inserted into the two clamping grooves on the outside of the second ring buckle 130. The bolts inside will fix the measuring tape 120. Then, one end of the cable is passed through the inside of the first ring buckle 110 and the second ring buckle 130. Next, adjust the screws in the two main pressure members 140 inside the first ring buckle 110 and the second ring buckle 130. When the screws rotate clockwise, the main pressure members 140 will press down on the cable, and at the same time, drive the pressure boosting sleeve 160 and the two arc strips 170 to extend downward. At this time, the pull rod 180, which is movably connected to the bottom of the two arc strips 170, can push the auxiliary pressure member 150 to lift and tighten towards the bottom of the cable. At this time, the combined first ring buckle 110 and second ring buckle 130 can pre-tension the outer layer of the cable to be ring-cut vertically. Then, adjust the rotation of the screw cylinder 350. At this time, the screw cylinder 350 will... The crossbar 360 is moved closer to the guide washer 310 until the inner end of the crossbar 360 is inserted into the slot on the inner side of the guide washer 310. At this time, the cutting end 390 connected inside the guide washer 310 will press down towards the outer layer of the cable. When the cutting end 390 penetrates into the insulation layer of the cable, the user can start the motor 260 to run. At this time, the track connected to the shaft of the motor 260 can drive the fixed wheel 380 and the guide washer 310 to rotate synchronously. At this time, the guide washer 310 inserted by the crossbar 360 can drive the second slip ring 340 and the first slip ring 330 to rotate along the outside of the cable. At this time, the cutting end 390 can perform circumferential cutting of the cable at a stable speed.
