The cutter 500 is installed on the position adjustment mechanism 400, and the cutter 500 is used to cut the aluminum sheath of the cable 600. The position adjustment mechanism 400 is used to drive the cutter 500 and move along the radial direction of the cable 600. The position adjustment mechanism 400 can control the depth of the cutter 500 cutting the aluminum sheath of the cable 600. The length direction of the scale 111 is consistent with the moving direction of the cutter 500, and the pointer 451 moves with the cutter 500, and the pointer 451 points to the scale 111. The pointer 451 and the scale 111 are used to indicate the position information of the cutter 500.

[0074] The cable aluminum sheath longitudinal cutting device is easy to load and unload and simple to operate. The pointer 451 and the scale 111 are used to read the data, so that the cutting depth of the aluminum sheath of the cable 600 can be accurately controlled to avoid damaging the semi-conductive layer of the cable 600. The electric cutter 500 is used as the power source, and the cutting efficiency is high. The elastic component 300 is used, and the cable aluminum sheath longitudinal cutting device can adapt to the change of the diameter of the cable 600 to ensure smooth cutting.

[0075] In some embodiments, see Figure 1 and Figure 7The first guide assembly 210 is provided on the first mounting seat 200, and the first guide assembly 210 includes a first guide shaft 211, a first guide roller 212, a second guide shaft 213 and a second guide roller 214. The first guide shaft 211 and the second guide shaft 213 are installed on the first mounting seat 200, and the first guide roller 212 is rotatably connected to the first guide shaft 211, and the first guide roller 212 abuts against the aluminum sheath of the cable 600. The second guide roller 214 is rotatably connected to the second guide shaft 213, and the second guide roller 214 abuts against the aluminum sheath of the cable 600. The first guide shaft 211 and the second guide shaft 213 are both tilted relative to the first mounting seat 200, and the first guide shaft 211 and the second guide shaft 213 are away from each other in a direction away from the first mounting seat 200.

[0076] A first guide assembly 210 is provided on the first mounting seat 200, and a first guide roller 212 and a second guide roller 214 clamp the aluminum sheath of the cable 600. During the cutting process of the aluminum sheath of the cable 600 by the cable aluminum sheath longitudinal cutting device, the first guide roller 212 and the second guide roller 214 roll, and the friction resistance is small, and the cutting is effortless.

[0077] In some embodiments, see Figure 1 and Figure 7 , two guide mounting seats 215 are arranged on the first mounting seat 200, and the guide mounting seats 215 are arranged in an L shape. The two guide mounting seats 215 are arranged opposite to each other, and the two first guide shafts 211 are connected to the opposite sides of the guide mounting seat 215, and the two ends of the first guide shaft 211 are connected to the two ends of the guide mounting seat 215. The two second guide shafts 213 are connected to the opposite sides of the guide mounting seat 215, and the two ends of the second guide shaft 213 are connected to the two ends of the guide mounting seat 215. A avoidance groove is arranged on the guide mounting seat 215 corresponding to the position of the first guide roller 151. The guide mounting seat 215 is detachably connected to the first mounting seat 200 by bolts, and the first guide shaft 211 and the second guide shaft 213 are detachably connected to the guide mounting seat 215 by bolts, which can facilitate the disassembly and assembly of the first guide assembly 210.

[0078] In some embodiments, see Figure 1 , Figure 2 and Figure 3The position adjustment mechanism 400 includes a plurality of guide rods 410, a plurality of guide sleeves 420, an adjustment screw 430, a nut sleeve 440, a movable plate 450 and a rotating handle 460. The plurality of guide rods 410 are mounted on the bracket 100, and the plurality of guide sleeves 420 are slidably sleeved on the plurality of guide rods 410 in a one-to-one correspondence. One end of the adjustment screw 430 is rotatably connected to the bracket 100, and the other end is connected to the rotating handle 460. The nut sleeve 440 is threadedly connected to the adjustment screw 430, and the nut sleeve 440 and the plurality of guide sleeves 420 are mounted on the movable plate 450, and the cutter 500 and the pointer 451 are mounted on the movable plate 450.

[0079] The axial direction of the guide rod 410 is parallel to the axial direction of the adjusting screw 430. A plurality of guide sleeves 420 are slidably mounted on a plurality of corresponding guide rods 410, and the guide sleeves 420 are mounted on the movable plate 450 to ensure that the movable plate 450 is evenly stressed and moves stably, and that the movable plate 450 can only move along the axial direction of the guide rod 410. The rotating handle 460 is convenient for manual holding, and the adjusting screw 430 can be rotated with less effort. Rotating the rotating handle 460 drives the adjusting screw 430 to rotate, drives the nut sleeve 440 to move up and down along the axial direction of the adjusting screw 430, and drives the movable plate 450 to move up and down along the axial direction of the adjusting screw 430.

[0080] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The position adjustment mechanism 400 further includes an upper limit block 470, which is spaced apart from the bracket 100. A rotation hole is provided in the middle of the upper limit block 470, through which the adjustment screw 430 passes, and two guide rods 410 are connected at both ends of the upper limit block 470. The movable plate 450 is located between the upper limit block 470 and the bracket 100. The upper limit block 470 is provided to limit the upper and lower position adjustment range of the movable plate 450. The upper limit block 470 is connected to the two guide rods 410 to increase the stability of the assembly.

[0081] In some embodiments, see Figure 1 , Figure 7 , Figure 8 and Fig. 9, a fixing groove 220 is provided on the first mounting seat 200. The elastic component 300 includes a spring 310, a sliding guide sleeve 320, and a cover plate 330. The spring 310 is installed in the fixing groove 220, one end of which abuts against the bottom wall of the fixing groove 220, and the other end abuts against the sliding guide sleeve 320. One end of the sliding guide sleeve 320 extends into the fixing groove 220, and the other end of the sliding guide sleeve 320 abuts against the bracket 100. An annular protrusion 321 is provided on the outer side of the sliding guide sleeve 320 near one end of the spring 310. The cover plate 330 is installed on the first mounting seat 200, and a first through hole is provided on the cover plate 330. The first through hole is sleeved on the sliding guide sleeve 320, and the outer diameter of the annular protrusion 321 is greater than the inner diameter of the first through hole.

[0082] The cover plate 330 is used to limit the sliding guide sleeve 320, ensuring that the end of the sliding guide sleeve 320 with the annular protrusion 321 will not fall out of the fixing groove 220. After the first mounting seat 200 is mounted on the bracket 100, the first mounting seat 200 abuts against the aluminum sheath of the cable 600, and the bracket 100 can be adjusted to squeeze the sliding guide sleeve 320, and the sliding guide sleeve 320 squeezes the spring 310. When the bracket 100 is pushed along the axial direction of the aluminum sheath of the cable 600, when the diameter of the aluminum sheath of the cable 600 increases, the aluminum sheath of the cable 600 pushes the first mounting seat 200 away from the bracket 100, and the first mounting seat 200 squeezes the spring 310; when the diameter of the aluminum sheath of the cable 600 decreases, the spring 310 pushes the first mounting seat 200 against the aluminum sheath of the cable 600; it is ensured that the cable aluminum sheath longitudinal cutting device can adapt to the change of the diameter of the cable 600 to ensure smooth cutting.

[0083] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The bracket 100 includes a second mounting seat 110, and the second mounting seat 110 is spaced apart from the first mounting seat 200. The position adjustment mechanism 400 and the pointer 451 are both mounted on the second mounting seat 110. A limiting groove 112 is provided on the side of the second mounting seat 110 close to the first mounting seat 200. The limiting groove 112 is used to cooperate with the first mounting seat 200 to clamp the aluminum sheath of the cable 600. The two side walls of the limiting groove 112 are away from each other in the direction close to the first mounting seat 200, and the cross-section of the limiting groove 112 is trapezoidal. The two side walls of the limiting groove 112 are inclined, which can ensure that the aluminum sheath of the cable 600 is closer to the bottom wall of the limiting groove 112 and closer to the cutter 500, saving the working space of the cable aluminum sheath longitudinal cutting device and ensuring the compactness of the assembly. The two side walls of the limiting groove 112 can also abut against the aluminum sheath of the cable 600. When the aluminum sheath of the cable 600 is clamped, the aluminum sheath of the cable 600 can be restricted from shaking left and right, thereby ensuring the stability of the clamped aluminum sheath.

[0084] In some embodiments, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The second guide assembly 150 is provided on the second mounting seat 110. The second guide assembly 150 is located on the bottom wall of the limiting groove 112. The second guide assembly 150 abuts against the aluminum sheath of the cable 600. For the aluminum sheath of the cable 600 with a smooth surface, the second guide assembly 150 uses a roller 151. The roller 151 abuts against the aluminum sheath of the cable 600 and cooperates with the first guide assembly 210 to clamp the aluminum sheath of the cable 600, forming a three-point support for stable clamping. In addition, the roller 151 is provided. When the cable aluminum sheath longitudinal cutting device is in the process of cutting the smooth aluminum sheath cable 600, the roller 151 rolls, the friction resistance is small, and the cutting is not difficult.

[0085] For the corrugated aluminum sheathed cable 600, the roller 151 is removed from the second mounting seat 110, and the sliding pad 152 is installed on the second mounting seat 110. The contact length between the sliding pad 152 and the cable 600 must be greater than the distance between two adjacent wave peaks on the cable 600 to ensure normal cutting, so as to avoid the sliding pad 152 sliding into the trough between two adjacent wave peaks, causing the cable 600 to shake and affecting the cutting accuracy. The sliding pad 152 is set to abut against the corrugated aluminum sheathed cable 600, so as to ensure that the cable 600 will not shake during the cutting process of the aluminum sheathed cable 600 by the cable aluminum sheath longitudinal cutting device, thereby ensuring smooth and accurate cutting.

[0086] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The sliding pad 152 includes a sliding portion 1521 and a guide portion 1522. The sliding portion 1521 is connected to the bottom wall of the limiting groove 112. The guide portion 1522 is bent and extended in a direction away from the first mounting seat 200, and the guide portion 1522 extends out of the limiting groove 112. The guide portion 1522 and the sliding portion 1521 are bent and extended to ensure that the connection between the guide portion 1522 and the sliding portion 1521 is a smooth arc surface, so as to prevent the sliding pad 152 from scratching the aluminum sheath of the cable 600 and to prevent the edge of the sliding pad 152 from pressing against the aluminum sheath of the cable 600, so that the cable aluminum sheath longitudinal cutting device is difficult to move during the cutting process of the aluminum sheathed cable 600.

[0087] In some embodiments, see Figure 1 , Figure 2 and Fig.10The bracket 100 also includes a fixing rod 120, a pressing plate 130 and a locking nut 140. One end of the fixing rod 120 is connected to the second mounting seat 110, and the other end is provided with an external thread. The first mounting seat 200 is detachably connected to the fixing rod 120. A second through hole 131 is provided on the pressing plate 130, and the second through hole 131 is arranged corresponding to the position of the fixing rod 120. The fixing rod 120 passes through the second through hole 131, and the pressing plate 130 abuts against the elastic component 300. The locking nut 140 is threadedly connected to the fixing rod 120 and abuts against the pressing plate 130. The first mounting seat 200 and the second mounting seat 110 are connected through the fixing rod 120, and the fixing rod 120 is threadedly connected to the locking nut 140, which is convenient for disassembly and assembly. A pressure plate 130 is set to abut the elastic component 300, and the aluminum sheath of the cable 600 is placed behind the first mounting seat 200 and the second mounting seat 110. The first mounting seat 200 abuts the aluminum sheath of the cable 600. The pressure plate 130 can be used to extrude the elastic component 300, and the cable aluminum sheath longitudinal cutting device can adapt to the change of the diameter of the cable 600 to ensure smooth cutting.

[0088] In some embodiments, see Figure 1 , Figure 2 , Figure 8 and Fig.10 The fixing rod 120 includes a first section 121 and a second section 122. The diameter of the first section 121 is larger than the diameter of the second section 122. The first section 121 is connected to the second mounting seat 110, and an external thread is provided on the second section 122. A fixing guide sleeve 240 is provided on the first mounting seat 200. The fixing guide sleeve 240 is sleeved on the second section 122, and the inner diameter of the fixing guide sleeve 240 is smaller than the diameter of the first section 121. The diameter of the first section 121 is set to be larger than the diameter of the second section 122. The connection between the first section 121 and the second section 122 is in a step shape. The fixing guide sleeve 240 is sleeved on the second section 122. The connection between the first section 121 and the second section 122 can limit the moving range of the fixing guide sleeve 240, thereby limiting the minimum distance between the first mounting seat 200 and the second mounting seat 110, and preventing the cutter 500 from cutting the first mounting seat 200.

[0089] In some embodiments, see Figure 1 , Figure 2 , Figure 8 and Fig. 9 The bottom wall of the fixing groove 220 is provided with a third through hole 230, the fixing rod 120 passes through the third through hole 230 and the fixing groove 220, and the fixing rod 120 passes through the elastic component 300, the pressure plate 130 and is connected with the locking nut 140. The elastic component 300 is sleeved on the fixing rod 120, and the elastic component 300 can be compressed and restored along the axis direction of the fixing rod 120. The fixing rod 120 can limit the left and right shaking of the elastic component 300 when compressed, and can ensure the compression stability of the elastic component 300.

[0090] In some embodiments, see Figure 1 , Figure 2 , Figure 5 and Fig.10 The second mounting seat 110 is provided with a push handle 114, which is used for convenient manual holding, and can ensure that the cable aluminum sheath longitudinal cutting device can cut smoothly. The second mounting seat 110 is provided with a cutting hole 113, and the cutting hole 113 is connected to the limiting groove 112. The cutter 500 includes a saw blade 510. When the cable aluminum sheath longitudinal cutting device cuts the aluminum sheath of the cable 600, the saw blade 510 extends into the limiting groove 112 along the cutting hole 113 to cut the aluminum sheath of the cable 600.

[0091] See also Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig.11 The present application also provides a method for longitudinally cutting a cable aluminum sheath, comprising the following steps:

[0092] Step S1: Adjust the position adjustment mechanism 400 to drive the cutter 500 to be located at the farthest end of the bracket 100 away from the first mounting seat 200, and remove the first mounting seat 200 from the bracket 100. Adjust the rotating handle 460 to adjust the nut sleeve 440 to the position abutting the upper limit block 470, and then remove the locking nut 140, the pressure plate 130, and the first mounting seat 200 from the fixing rod 120 in sequence. Determine whether the aluminum sheath of the cable 600 is a corrugated aluminum sheath. If it is a corrugated aluminum sheath, remove the roller 151 from the second mounting seat 110, and install the sliding pad 152 on the second mounting seat 110.

[0093] Step S2: The bracket 100 is mounted on the aluminum sheath of the cable 600, and the first mounting seat 200 is mounted on the bracket 100. The first mounting seat 200 and the bracket 100 clamp the aluminum sheath of the cable 600. The bracket 100 is mounted on the cable 600, and the first mounting seat 200, the pressing plate 130 and the locking nut 140 are mounted on the fixing rod 120.

[0094] Step S3: Adjust the bracket 100 to squeeze the elastic component 300, and compress the length of the elastic component 300 by 3 to 4 mm. Adjust the locking nut 140, and compress the length of the spring 310 by 3 to 4 mm through the pressing plate 130 and the sliding guide sleeve 320.

[0095] Step S4: Adjust the position adjustment mechanism 400 to drive the cutter 500 to contact the aluminum sheath of the cable 600, and record the reading when the pointer 451 points to the scale 111. The reading at this time is the initial value. Adjust the rotating handle 460. When the saw blade 510 of the cutter 500 is attached to the aluminum sheath of the cable 600, stop adjusting and record the reading when the pointer 451 points to the scale 111 (initial value).

[0096] Step S5: Start the cutter 500, adjust the position adjustment mechanism 400, drive the cutter 500 to cut the aluminum sheath of the cable 600 in the direction close to the first mounting seat 200, observe the reading of the scale 111 pointed by the pointer 451, the reading at this time is the adjustment value, when the difference between the adjustment value and the initial value is equal to the thickness of the aluminum sheath of the cable 600, stop adjusting the position adjustment mechanism 400. Start the cutter 500, slowly adjust the rotating handle 460 again, and at the same time, observe the reading (adjustment value) pointed by the pointer 451 to the scale 111, when the difference between the adjustment value and the initial value is equal to the thickness of the aluminum sheath of the cable 600, stop adjusting the rotating handle 460.

[0097] Step S6: Push the support 100 along the axial direction of the cable 600 to perform longitudinal cutting. When the aluminum sheath of the cable 600 is longitudinally cut to a specified length, the longitudinal cutting is completed and the cutter 500 is closed. Hold the push handle 114 and slowly push the device along the cable 600 to perform longitudinal cutting. When the longitudinal cutting reaches a specified distance, the cutter 500 is closed.

[0098] Step S7: Adjust the position adjustment mechanism 400 to drive the cutter 500 away from the cable 600, remove the first mounting seat 200 from the bracket 100, and remove the bracket 100 from the cable 600. Adjust the rotating handle 460 to make the saw blade 510 leave the surface of the cable 600, then remove the locking nut 140, the pressure plate 130, and the first mounting seat 200 from the fixing rod 120, and finally remove the bracket 100 from the cable 600.

[0099] The cable aluminum sheath longitudinal cutting device is easy to load and unload and simple to operate. The pointer 451 and the scale 111 are used to read the data, so that the cutting depth of the aluminum sheath of the cable 600 can be accurately controlled to avoid damaging the semi-conductive layer of the cable 600. The electric cutter 500 is used as the power source, and the cutting efficiency is high. The elastic component 300 is used, and the cable aluminum sheath longitudinal cutting device can adapt to the change of the diameter of the cable 600 to ensure smooth cutting.
