Description

Cable stripping device and cable stripping method Technical Field

[0001] The invention relates to the technical field of cable stripping, in particular to a cable stripping device and a cable stripping method. Background Art

[0002] During power supply construction, a large number of cables are required. When a single cable needs to be connected to other equipment or two cables need to be connected, a certain length of insulation needs to be stripped. Currently, most workers use electrician's knives to remove the insulation of the cables. However, this method of hand-held electrician's knives can easily scratch the cable core, so it requires a high level of worker experience. When performing large-scale cable stripping operations, the high labor intensity leads to low overall work efficiency.

[0003] Prior art invention patent CN112242673A discloses an insulated cable stripper and stripping method. This patent's technical solution uses a size-adjusting mechanism to raise or lower a cutting blade. The cable to be stripped is then placed within a stripping chamber, with two bevel gears clamping the cable. A power mechanism is activated to drive the bevel gears forward, and the cutting blade cuts the insulation on the cable to the desired length. However, after stripping the insulation, the device requires circumferential cutting to remove the cable, which reduces the efficiency of large-scale stripping. Summary of the Invention

[0008] The end of the first turntable is provided with a central axis rotatably connected to the sleeve, and the end of the central axis is symmetrically provided with a protrusion. The base is provided with an annular groove and a spiral groove connected to the annular groove along the circumferential direction. The protrusion slides on the annular groove and the spiral groove in turn, driving the cutting knife to move circumferentially and spirally on the cable surface respectively.

[0009] Furthermore, a plurality of limiting wheels are rotatably connected to the central shaft, a plurality of limiting blocks are slidably connected to the sleeve, the ends of the limiting blocks are provided with inclined surfaces in contact with the limiting wheels, and a reset spring is provided between the limiting blocks and the limiting wheels.

[0011] Furthermore, an adjusting block is slidably connected to the base, a guide rod slidably connected to the adjusting block is provided on one side of the clamping block, the clamping spring is arranged between the clamping block and the adjusting block, and a stop block is provided at the end of the guide rod that contacts the adjusting block.

[0012] Furthermore, a first screw is threadedly connected to the base, a protrusion is provided at the end of the first screw, and a groove rotatably connected to the protrusion is provided on the adjustment block, and both sides of the protrusion are in contact with the groove.

[0013] Furthermore, the end of the cutting knife is tapered, the support rod is provided with a mounting block slidably connected to the cutting knife, the mounting block is threadedly connected to a fixing rod, and the end of the fixing rod is threadedly connected to the cutting knife.

[0014] Furthermore, a friction block is symmetrically and slidingly connected to the base, and the end of the friction block is provided with a plurality of friction parts that contact the positioning block.

[0015] Furthermore, the base is rotatably connected to a second screw threadedly connected to the friction block, the end of the second screw is provided with a first conical tooth, the base is provided with a rotating motor, and the movable end of the rotating motor is provided with a second conical tooth that simultaneously engages with the two first conical teeth.

[0016] A cable stripping method comprising the following steps:

[0017] S1. According to the required cable stripping thickness, slide the cutting knife on the support rod in advance and adjust the position of the cutting knife on the support rod so that when the roller contacts the cable stripping, the cutting knife just pierces the cable skin. According to the required cable stripping length, change the position of the positioning block;

[0018] S2. Pass the cable between the two clamping blocks. The rebound force generated by the compression of the clamping spring drives the two clamping blocks to slide on the base until the ends of the clamping blocks contact the cable. Continue to move the cable radially until the head of the cable contacts the end of the positioning block, thus limiting the movement of the cable along the axis.

[0019] S3. After the overall balance is restored, the second turntable is rotated on the sleeve so that the arc groove contacts the support rod, and the component force generated drives it to move inward in the arc groove, and cooperates with the guide groove to guide the support rod, so that the support rod moves radially inward, driving the roller and cutting knife provided on the support rod to move until the roller contacts the side of the cable, so that the cutting knife just pierces the cable skin; then the second turntable is further rotated on the sleeve to drive the support rod to continue moving, and the force generated after the support rod contacts the guide groove will drive the first turntable to rotate together with the second turntable, so that the roller moves on the cable skin; at the same time, the protrusion slides on the annular groove and the spiral groove in turn, driving the cutting knife to move circumferentially and axially on the cable surface respectively, so that the cutting knives on both sides of the cable cut the cable skin circumferentially and axially spirally in turn.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Pass the cable between the two clamping blocks. The rebound force generated by the compression of the clamping spring drives the two clamping blocks to slide on the base until the ends of the clamping blocks contact the cable, thereby achieving radial positioning and clamping of the cable, preventing the cable from shifting during the cutting process and affecting the effect of cable stripping;

[0022] Continue to move the cable radially until the cable head contacts the end of the positioning block, limiting the cable's movement along the axis and positioning the cable axially, ensuring that the length of the cable remains consistent after stripping, thereby improving the stripping effect. At the same time, the position of the positioning block can be changed as needed to change the cable stripping length.

[0023] 2. Rotate the second turntable on the sleeve. Through the coordination among the sleeve, the second turntable, the arc groove, the support rod, the guide groove, the roller and the cutting knife, the roller contacts the side of the cable. In addition, by sliding the cutting knife on the support rod in advance, the position of the cutting knife on the support rod is adjusted so that the cutting knife can just pierce the cable skin. When cutting the skin of cables with the same thickness at the same time, since the positions of the cutting knife and the roller are relatively fixed, there is no need to reposition the position of the cutting knife. The positioning of the cutting knife can be achieved by only contacting the roller with the cable skin, thereby improving the stripping efficiency of large quantities of cables with consistent skin thickness.

[0024] The second rotary disc is further rotated on the sleeve, and the first rotary disc rotates together with the second rotary disc through the cooperation among the support rod, the roller, the cable, and the guide groove, driving the roller to move on the cable surface; at the same time, through the cooperation among the protrusion, the annular groove, and the spiral groove, the cutting knife is driven to move circumferentially and axially on the cable surface, respectively, so that the cutting knives on both sides of the cable cut the cable surface circumferentially and axially in spiral cutting in turn, thereby realizing circumferential cutting of the cable surface and axial spiral cutting of the cable surface. There is no need to replace the knife group or change the direction subsequently, and cutting in two different directions can be realized, and there is no need to manually cut the cable, thereby improving the efficiency and effect of cutting;

[0025] 3. The second turntable rotates on the sleeve through the cooperation between the driving motor, the driving gear, and the driven gear. When the second turntable starts to rotate, the cooperation between the limit block, the inclined surface, the limit wheel, and the return spring prevents the second turntable from directly driving the first turntable to move, so that the second turntable can smoothly drive the support rod to move radially on the first turntable.

[0026] Until the roller on the support rod contacts the surface of the cable, the resistance generated limits the movement of the support rod on the first turntable. When the second turntable is further rotated, the first turntable moves along with the second turntable through the cooperation between the first turntable, the return spring, the limit wheel and the limit block, so that the first turntable rotates spirally on the base to achieve cutting of the cable surface. At the same time, there is no need to drive the first turntable and the second turntable to rotate separately, which reduces the cost of manufacturing the power device and the space required for installation.

[0027] 4. By cooperating among the base, the first screw, the protrusion, the groove, and the adjusting block, the compression amount of the clamping spring is changed, so that the size of the clamping force applied to the clamping block can adapt to cables with different outer diameters, achieve stable clamping of cables with different outer diameters, and improve the effect of cable stripping; the clamping spring is sleeved on the outside of the guide rod to guide the clamping spring, preventing it from popping out of the base after compression, thereby ensuring overall stability; when the cable is removed, the stopper contacts the adjusting block, preventing the clamping block from sliding out of the base, thereby ensuring overall stability;

[0028] 5. The cutting knife is fixed on the support rod through the cooperation among the mounting block, fixing rod, cutting knife and support rod, which avoids the cutting knife from being offset during the cutting process, which affects the cutting effect of cable stripping. In addition, the tapered cutting knife can better cut along the circumferential direction and radial spirally on the cable surface, thus improving the effect of cutting and stripping the cable.

[0029] 6. By rotating the motor, the second conical teeth, the first conical teeth, the second screw, the base, the friction block, the friction part and the positioning block, the positioning block is released, which makes it easier to adjust the position of the positioning block and change the cable stripping length to meet the requirements of the cable wiring process. Similarly, the two friction blocks are driven by the rotating motor to move inward at the same time, so that the friction part contacts the positioning block to fix the positioning block, avoiding the cable contacting the positioning block after a long period of stripping, causing it to deviate from its original position, resulting in the subsequent cable stripping length being inconsistent with the initially set length, thereby improving the effect of cable stripping. At the same time, there is no need to drive the two friction blocks to move separately, reducing the cost of power device manufacturing and the space required for installation.

DETAILED DESCRIPTION

[0042] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0043] The present invention provides a cable stripping device, as shown in Figures 1-6, comprising a clamping mechanism 3 and a rotary cutting mechanism 4 arranged on a base 1 and used in conjunction with a cable 2, respectively realizing the clamping of the cable 2 and the cutting of the cable 2 skin, thereby eliminating the need for manual cutting of the cable 2 skin and improving the efficiency and effect of batch cutting of the cable 2 skin; the clamping mechanism 3 comprises clamping blocks 5 symmetrically arranged on both sides of the cable 2, the clamping blocks 5 being slidably connected to the base 1, and a clamping spring 6 being provided between the clamping blocks 5 and the base 1, and the cable 2 is passed through the two clamping blocks 5, and the rebound force generated by the compression of the clamping spring 6 drives the two clamping blocks 5 to slide on the base 1 until the ends of the clamping blocks 5 contact the cable 2, thereby realizing radial positioning and clamping of the cable 2, and preventing the cable 2 from shifting position during the cutting process, which affects the effect of the cable 2 after stripping;

[0044] The base 1 is slidably connected with a positioning block 7 in contact with the end of the cable 2, so that the head of the cable 2 contacts the end of the positioning block 7, restricting the movement of the cable 2 along the axis, and playing a role in axial positioning of the cable 2, ensuring that the length of the cable 2 after stripping remains consistent, thereby improving the effect of the cable 2 stripping; at the same time, the position of the positioning block 7 can be changed as needed, thereby changing the length of the cable 2 stripping;

[0045] The rotary cutting mechanism 4 includes a sleeve 8 slidably connected to the base 1, and a first turntable 9 rotatably connected to the sleeve 8, a plurality of guide grooves 10 are provided on the first turntable 9 in the radial direction, a plurality of support rods 11 are slidably connected in the guide grooves 10, and a roller 12 that is in rolling contact with the side of the cable 2 is rotatably connected to the support rods 11, wherein two of the support rods 11 are slidably connected to cutters 13 used in conjunction with the surface of the cable 2; and a second turntable 14 rotatably connected to the sleeve 8 is provided on the second turntable 14, and an arc groove 15 that is in sliding contact with the support rod 11 is provided on the second turntable 14. By rotating the second turntable 14 on the sleeve 8, the arc groove 15 is rotatably connected to the second turntable 14. The component force generated by the contact with the support rod 11 drives it to move inward in the arc groove 15, and cooperates with the guidance of the guide groove 10 on the support rod 11, so that the support rod 11 moves radially inward, driving the roller 12 and the cutting knife 13 provided on the support rod 11 to move until the roller 12 contacts the side of the cable 2. In addition, by sliding the cutting knife 13 on the support rod 11 in advance, adjusting the position of the cutting knife 13 on the support rod 11, so that the cutting knife 13 can just pierce the skin of the cable 2. When cutting the skin of the cable 2 of the same thickness at the same time, since the positions of the cutting knife 13 and the roller 12 are relatively fixed, there is no need to reposition the position of the cutting knife 13, and only the roller 12 needs to be moved. 2 contacts the surface of the cable 2, the positioning of the cutting knife 13 can be achieved, thereby improving the stripping efficiency of a large number of cables 2 with uniform surface thickness; then, the second turntable 14 is further rotated on the sleeve 8 to drive the support rod 11 to continue to move. Since the roller 12 contacts the surface of the cable 2, the support rod 11 is restricted from moving radially inward. Therefore, the force generated after the support rod 11 contacts the guide groove 10 will drive the first turntable 9 to rotate together with the second turntable 14, so that the roller 12 moves on the surface of the cable 2, cooperates with the cutting knife 13 to cut the surface of the cable 2, and then realizes the cutting of the cable 2 surface. At the same time, there is no need to manually cut the surface of the cable 2, which improves the efficiency of batch production. Efficiency and effect of cutting the surface of the cable 2; the end of the first turntable 9 is provided with a central axis 16 rotatably connected to the sleeve 8, and the end of the central axis 16 is symmetrically provided with a protrusion 17. The base 1 is circumferentially provided with an annular groove 18 and a spiral groove 19 connected to the annular groove 18. The protrusion 17 slides on the annular groove 18 and the spiral groove 19 in turn, driving the cutting knife 13 to move circumferentially and spirally on the surface of the cable 2, respectively, to achieve circumferential cutting of the surface of the cable 2 and spiral cutting along the axial direction.

The end of the limiting block 21 is provided with an inclined surface 22 that contacts the limiting wheel 20, and a return spring 23 is provided between the limiting block 21 and the limiting wheel 20. When the second turntable 14 just starts to rotate, the inclined surface 22 provided on one side of the limiting block 21 contacts the limiting wheel 20, driving the limiting block 21 to move outward and compressing the return spring 23, so that the return spring 23 generates a rebound force, which limits the limiting wheel 20 from passing through the limiting block 21, thereby preventing the second turntable 14 from directly driving the first turntable 9 The movement allows the second turntable 14 to smoothly drive the support rod 11 to move radially on the first turntable 9 until the roller 12 on the support rod 11 contacts the surface of the cable 2. The resistance generated limits the movement of the support rod 11 on the first turntable 9. When the second turntable 14 is further rotated, the force driving the first turntable 9 to rotate is greater than the rebound force generated by the compression of the return spring 23, so that the limiting wheel 20 smoothly passes through the limiting block 21, and then the first turntable 9 moves with the second turntable 14 to achieve cutting of the cable 2 surface.

[0053] The present invention provides a cable stripping method, as shown in FIG1-6, comprising the following steps:

[0054] S1. According to the required cable 2 stripping thickness, slide the cutting knife 13 on the support rod 11 in advance, and adjust the position of the cutting knife 13 on the support rod 11 so that when the roller 12 contacts the cable 2 stripping, the cutting knife 13 just pierces the cable 2 skin. According to the required cable 2 stripping length, change the position of the positioning block 7;

[0055] S2. Pass the cable 2 through the two clamping blocks 5. The rebound force generated by the compression of the clamping spring 6 drives the two clamping blocks 5 to slide on the base 1 until the end of the clamping block 5 contacts the cable 2, thereby achieving radial positioning and clamping of the cable 2, avoiding the cable 2 from shifting position during the cutting process, which affects the effect of the cable 2 after peeling; continue to move the cable 2 radially until the head of the cable 2 contacts the end of the positioning block 7, limiting the movement of the cable 2 along the axis, playing a role in axial positioning of the cable 2, ensuring that the length of the cable 2 after peeling remains consistent, and improving the effect of the cable 2 after peeling;

[0056] S3. After the whole body returns to balance, the arc groove 15 is brought into contact with the support rod 11 by rotating the second turntable 14 on the sleeve 8. The component force generated drives it to move inward in the arc groove 15. Cooperating with the guide groove 10 to guide the support rod 11, the support rod 11 is moved radially inward, driving the roller 12 and the cutting knife 13 provided on the support rod 11 to move until the roller 12 contacts the side of the cable 2, so that the cutting knife 13 just pierces the skin of the cable 2. When cutting the skin of cables 2 of the same thickness, since the positions of the cutting knife 13 and the roller 12 are relatively fixed, there is no need to reposition the position of the cutting knife 13. Only the roller 12 needs to contact the skin of the cable 2 to achieve the positioning of the cutting knife 13, thereby improving the stripping efficiency of large quantities of cables 2 with consistent skin thickness; then the second turntable 14 is further rotated on the sleeve 8, Driving the support rod 11 to continue moving, the roller 12 contacts the surface of the cable 2, limiting the support rod 11 from moving radially inward. Therefore, the force generated after the support rod 11 contacts the guide groove 10 will drive the first turntable 9 to rotate together with the second turntable 14, so that the roller 12 moves on the surface of the cable 2. At the same time, the protrusion 17 slides on the annular groove 18 and the spiral groove 19 in turn, driving the cutting knife 13 to move circumferentially and spirally on the surface of the cable 2 respectively, so that the cutting knives 13 on both sides of the cable 2 cut the cable 2 skin circumferentially and spirally in the axial direction in turn, realizing circumferential cutting of the cable 2 skin and spiral cutting in the axial direction. There is no need to replace the knife group or change the direction subsequently, and cutting in two different directions can be achieved. There is no need to manually cut the cable 2, thereby improving the cutting efficiency and effect.

[0057] Example 1

[0058] The present invention provides a cable stripping device and a cable stripping method. As shown in FIG1-6, a cable 2 is passed between two clamping blocks 5. The two clamping blocks 5 are driven to slide on a base 1 by the resilience generated by the compression of a clamping spring 6 until the ends of the clamping blocks 5 contact the cable 2, thereby achieving radial positioning and clamping of the cable 2, and preventing the cable 2 from shifting during the cutting process, thereby affecting the effect of the cable 2 after stripping. The cable 2 is continued to be moved radially until the head of the cable 2 contacts the end of a positioning block 7, thereby limiting the movement of the cable 2 along the axis, and playing a role in axial positioning of the cable 2, ensuring that the length of the cable 2 after stripping remains consistent, thereby improving the effect of the cable 2 after stripping. At the same time, the position of the positioning block 7 can be changed as needed, thereby changing the length of the cable 2 after stripping.

[0059] After the whole returns to balance, the second turntable 14 is rotated on the sleeve 8 so that the arc groove 15 contacts the support rod 11. The component force generated drives it to move inward in the arc groove 15, and cooperates with the guide groove 10 to guide the support rod 11, so that the support rod 11 moves radially inward, driving the roller 12 and the cutting knife 13 provided on the support rod 11 to move until the roller 12 contacts the side of the cable 2. In addition, by sliding the cutting knife 13 on the support rod 11 in advance, the position of the cutting knife 13 on the support rod 11 is adjusted so that the cutting knife 13 just pierces the skin of the cable 2. When cutting the skin of cables 2 of the same thickness at the same time, since the positions of the cutting knife 13 and the roller 12 are relatively fixed, there is no need to reposition the position of the cutting knife 13. Only the roller 12 needs to contact the skin of the cable 2 to achieve the positioning of the cutting knife 13, thereby improving the efficiency of stripping large quantities of cables 2 with consistent skin thickness. After that, the second rotary disc 14 is further rotated on the sleeve 8, driving the support rod 11 to continue to move. However, due to the contact between the roller 12 and the surface of the cable 2, the support rod 11 is restricted from moving radially inward. Therefore, the force generated after the support rod 11 contacts the guide groove 10 will drive the first rotary disc 9 to rotate together with the second rotary disc 14, so that the roller 12 moves on the surface of the cable 2. At the same time, the protrusion 17 slides on the annular groove 18 and the spiral groove 19 in turn, driving the cutting knife 13 to move circumferentially and spirally on the surface of the cable 2 respectively, so that the cutting knives 13 on both sides of the cable 2 cut circumferentially and spirally cut the cable 2 skin in turn, realizing circumferential cutting of the cable 2 skin and spiral cutting in the axial direction. There is no need to replace the knife group or change the direction subsequently, and cutting in two different directions can be achieved, and there is no need to manually cut the cable 2, thereby improving the cutting efficiency and effect.

[0060] Example 2

[0061] On the basis of Example 1, as shown in Figure 1-9, the driving motor 25 drives the active gear 26 to rotate, driving the driven gear 24 meshing with the active gear 26 to rotate, so that the second turntable 14 rotates on the sleeve 8; when the second turntable 14 just starts to rotate, the inclined surface 22 provided on one side of the limit block 21 contacts the limit wheel 20, driving the limit block 21 to move outward and compressing the return spring 23, so that the return spring 23 generates a rebound force, limiting the limit wheel 20 from passing through the limit block 21, preventing the second turntable 14 from directly driving the first turntable 9 to move, so that the second turntable 14 smoothly drives the support rod 11 to move radially on the first turntable 9 until the roller 12 on the support rod 11 contacts the surface of the cable 2, and the resistance generated is limited. When the support rod 11 moves on the first turntable 9 and further rotates the second turntable 14, the force driving the first turntable 9 to rotate is greater than the rebound force generated by the compression of the return spring 23, so that the limiting wheel 20 passes through the limiting block 21 smoothly, thereby causing the first turntable 9 to move along with the second turntable 14, so that the first turntable 9 rotates spirally on the base 1, thereby achieving cutting of the surface of the cable 2. At the same time, there is no need to drive the first turntable 9 and the second turntable 14 to rotate separately, thereby reducing the cost of manufacturing the power device and the space required for installation; at the same time, the two sides of the limiting wheel 20 are in contact with the sleeve 8, driving the sleeve 8 to slide on the base 1, so that the driving motor 25 on the sleeve 8 can continuously drive the first turntable 9 to rotate, thereby ensuring the stability of the overall structure;

[0062] In addition, the second turntable 14 and the first turntable 9 are connected by the bearing 29, which limits the relative movement of the second turntable 14 and the first turntable 9 along the axial direction to ensure the overall stability; at the same time, the friction between the two is reduced, so that the second turntable 14 can rotate better relative to the first turntable 9, and the driving roller 12 and the cable 2 are prevented from contacting.

[0063] Example 3

[0064] On the basis of the first embodiment, as shown in FIG10 , when the outer diameter of the cable 2 changes, the first screw 33 is rotated on the base 1. Since the first screw 33 is threadedly connected to the base 1, the first screw 33 moves on the base 1. Since the second protrusion 34 provided at the end of the first screw 33 contacts the groove, the adjustment block 30 is driven to move on the base 1, thereby changing the compression amount of the clamping spring 6. The magnitude of the clamping force applied to the clamping block 5 is adapted to cables 2 with different outer diameters, thereby achieving stable clamping of cables 2 with different outer diameters and improving the stripping effect of the cable 2.

[0065] In addition, the clamping spring 6 is sleeved on the outside of the guide rod 31 to guide the clamping spring 6, preventing it from popping out of the base 1 after compression, thereby ensuring the overall stability; when the cable 2 is removed, the stop block 32 contacts the adjustment block 30, preventing the clamping block 5 from sliding out of the base 1, thereby ensuring the overall stability.

[0066] Example 4

[0067] On the basis of Example 1, as shown in Figures 2 and 3, after adjusting the position of the cutting knife 13, the fixing rod 36 is rotated on the mounting block 35 to move it on the mounting block 35 until its end contacts the cutting knife 13, thereby achieving the fixation of the cutting knife 13 on the support rod 11, avoiding the deviation of the cutting knife 13 during the cutting process, which affects the cutting effect of the cable 2 peeling; in addition, the conical setting of the cutting knife 13 can better cut along the circumferential direction and radial spiral cutting on the surface of the cable 2, thereby improving the effect of cutting and peeling the cable 2.

[0068] Example 5

[0069] On the basis of Example 1, as shown in Figure 11, when it is necessary to fix the positioning block 7, the second conical tooth 42 is driven to rotate by the rotating motor 41, and the two first conical teeth 40 are driven to rotate in the opposite direction, so that the two second screws 39 rotate in the opposite direction on the base 1, driving the two friction blocks 37 to move outward at the same time, releasing the contact between the friction part 38 and the positioning block 7, thereby releasing the fixation of the positioning block 7, facilitating the adjustment of the position of the positioning block 7, changing the stripping length of the cable 2, and meeting the requirements of the cable 2 wiring process; similarly, the two friction blocks 37 are driven to move inward at the same time by the rotating motor 41, so that the friction part 38 contacts the positioning block 7, thereby fixing the positioning block 7, avoiding the cable 2 from deviating from its original position after long-term stripping, resulting in the subsequent cable 2 stripping length being inconsistent with the initially set length, thereby improving the effect of the cable 2 after stripping; at the same time, there is no need to drive the two friction blocks 37 to move separately, reducing the cost of manufacturing the power device and the space required for installation.
