[0036] In this embodiment, as Figure 1And Figure 2 As shown in the figure, a multi-strand cable layered cutting and peeling device with double-sided fastening includes a U-shaped seat 1. A circumferential cutting assembly 2 is installed on the U-shaped seat 1. The circumferential cutting assembly 2 is used for layer-by-layer circumferential cutting of the cable. The circumferential cutting assembly 2 includes two connecting pipes 21, a cutting cylinder 22, a bearing plate 23, an adjusting member 24, a first motor 25, a cutter 26 and a driving member 27. The two connecting pipes 21 are symmetrically distributed at both ends of the cutting cylinder 22. The connecting pipes 21 are rotatably connected to the U-shaped seat 1 through bearings. The bearing plate 23 is installed in the cavity of the cutting cylinder 22. The adjusting member 24 is used to adjust the distance between the bearing plate 23 and the axis of the cutting cylinder 22. The first motor 25 is fixedly connected to the bearing plate 23. The cutter 26 is installed at the output end of the first motor 25. The driving member 27 is used to drive the bearing plate 23 to drive the cutter 26 to move horizontally, thereby changing the cutting depth of the cutter 26 on the cable. The cutter 26 drives the cutting cylinder 22 to rotate in the U-shaped seat 1 through the connecting pipe 21, and thus the cutter 26 in the cutting cylinder 22 performs circumferential cutting on the cable.

[0037] Therefore, the cable is passed through the cutting cylinder 22 and the connecting pipe 21, and both ends of the cable are fixed. The first motor 25 is started to drive the cutter 26 to rotate. The driving member 27 provides power to drive the bearing plate 23 to move. Then, the cutter 26 on the bearing plate 23 gradually approaches the axis of the cable, and the cable is cut at different depths. The connecting pipe 21 and the cutting cylinder 22 are rotated in the U-shaped seat 1. At the same time, the cutter 26 makes a circular motion along the outer wall of the cable to achieve circumferential cutting of the cable.

[0038] Furthermore, the U-shaped seat 1 is used to carry the connecting pipe 21 and the cutting cylinder 22. The connecting pipe 21 and the cutting cylinder 22 are interconnected. The connecting pipes 21 are symmetrically distributed at both ends of the cutting cylinder 22. The output end of the first motor 25 drives the cutter 26 to rotate, and the cutter 26 cuts the outer layer of the cable.

[0039] In some embodiments, as Figure 2 and Figure 3 shown, the driving member 27 includes a bushing 271, a transmission shaft 272, a second motor 273 and a backing plate 274. The bushing 271 is fixedly connected to the bearing plate 23. The transmission shaft 272 is threadedly connected to the bushing 271. The rotation of the transmission shaft 272 drives the bearing plate 23 to move horizontally through the bushing 271. The output end of the second motor 273 is connected to the transmission shaft 272 through a coupling. The backing plate 274 is fixedly connected to the bottom of the second motor 273. The backing plate 274 is fixedly connected to the cutting cylinder 22.

[0040] Furthermore, the second motor 273 is a servo motor. The second motor 273 provides power for the rotation of the transmission shaft 272. The backing plate 274 supports the second motor 273. The outer wall of the transmission shaft 272 is machined with threads. When the transmission shaft 272 rotates, it drives the bearing plate 23 to move laterally through the bushing 271.

[0041] In some embodiments, as Figure 3 shown, the adjusting member 24 includes a support rod 241 and a limiting cylinder 242. The support rod 241 is fixedly connected to the cutting cylinder 22. The limiting cylinder 242 is inserted on the support rod 241, and the limiting cylinder 242 is fixedly connected to the bearing plate 23.

[0042] Furthermore, there are two support rods 241 and two limiting cylinders 242 respectively. The support rod 241 moves horizontally in the limiting cylinder 242, and the bearing plate 23 drives the limiting cylinder 242 to move to adjust the position of the cutting knife 26.

The two fastening assemblies 3 are used to fix the two ends of the cable. The fastening assembly 3 includes a mounting disc 31, a connecting member 32, a double-headed threaded rod 33, a slider 34, a clamping plate 35 and a guiding member 36. The mounting disc 31 is connected to the connecting pipe 21 through the connecting member 32. The double-headed threaded rod 33 is rotatably connected to the mounting disc 31 through a bearing. The slider 34 is threadedly connected to the double-headed threaded rod 33. The clamping plate 35 is fixedly connected to the slider 34. The guiding member 36 restricts the clamping plate 35 to move in the horizontal direction.

[0044] Furthermore, a cavity is machined in the mounting disc 31. A turning knob is provided on the double-headed threaded rod 33. There are two sliders 34 on the double-headed threaded rod 33. When the double-headed threaded rod 33 rotates, it drives the two clamping plates 35 to move through the sliders 34.

[0045] In some embodiments, as Figure 4 shown, the connecting member 32 includes a bolt 321 and a mounting plate 322. The mounting plate 322 is fixedly connected to the connecting pipe 21. The mounting disc 31 is connected to the mounting plate 322 through the bolt 321.

[0046] Furthermore, two bolts 321 are provided in each mounting disc 31. The mounting plates 322 are symmetrically fixed on the outer wall of the connecting pipe 21. The bolts 321 connect the mounting disc 31 and the mounting plate 322.

[0047] In some embodiments, as Figure 3 shown, the guiding member 36 includes a through-hole plate 361 and a guiding rod 362. The through-hole plate 361 is fixedly connected to the clamping plate 35. The guiding rod 362 is inserted into the through-hole of the through-hole plate 361, and the guiding rod 362 is fixedly connected to the mounting disc 31.

[0048] Furthermore, through-hole plates 361 are fixedly connected to the bottom ends of the two clamping plates 35. Circular through-holes are machined in the through-hole plates 361. The through-hole plates 361 move on the outer wall of the guiding rod 362, so that the two clamping plates 35 move towards each other to clamp the cable.

[0049] In some embodiments, such as Figure 5 shown, a rubber pad 351 is fixedly connected in the splint 35, and strip-shaped lines are processed on the rubber pad 351.

[0050] Furthermore, the rubber pad 351 has plasticity, and the design of processing strip-shaped lines on the rubber pad 351 increases the friction between the rubber pad 351 and the cable.

[0051] In some embodiments, such as Figure 1 shown, a base 11 is fixedly connected to the U-shaped seat 1, and an installation chute 12 is provided in the base 11.

[0052] Furthermore, the base 11 bears the overall mechanism, the installation chutes 12 are distributed at the four corners of the base 11, and the setting of the installation chutes 12 facilitates the fixing of the installation position of the base 11 by expansion bolts.

[0053] In some embodiments, such as Figure 1 shown, a plurality of handwheels 211 are fixedly connected to one of the connecting pipes 21, and the handwheels 211 are evenly distributed along the connecting pipe 21.

[0054] Furthermore, four handwheels 211 are provided on one of the connecting pipes 21, and the connecting pipe 21 is driven to rotate in the U-shaped seat 1 by the handwheels 211.

[0055] In some embodiments, such as Figure 4 shown, an observation window 221 is provided in the cutting cylinder 22, and the observation window 221 is made of transparent plastic.

[0056] Furthermore, the design of the observation window 221 facilitates observing the cutting condition of the cable in the cutting cylinder 22.

[0057] The working principle of the present application will be described below with a relatively preferred embodiment:

[0058] First, pass the cable to be cut through one connecting pipe 21. The cable passes through the cutting cylinder 22 and exits from the other connecting pipe 21. Subsequently, rotate the double-headed threaded rod 33 in the mounting plate 31. When the double-headed threaded rod 33 rotates, it drives the clamping plates 35 to move towards each other through the sliders 34. At the same time, the clamping plates 35 drive the through-hole plate 361 to move along the guiding rod 362. The rubber pads 351 in the two clamping plates 35 clamp the cable. Then, start the second motor 273. The second motor 273 drives the transmission shaft 272 to rotate through the coupling. Further, the transmission shaft 272 pulls the bearing plate 23 to move horizontally through the sleeve 271. The bearing plate 23 drives the limiting cylinder 242 to move on the outer wall of the support rod 241. At the same time, the cutter 26 cuts into the cable. Subsequently, drive the connecting pipe 21 to rotate in the U-shaped seat 1 through the handwheel 211. At this time, the U-shaped seat 1 drives the cutter 26 to perform a circumferential cut on the cable. Drive the bearing plate 23 to move horizontally through the sleeve 271 to change the depth at which the cutter 26 cuts into the cable, thereby realizing circumferential cuts at different levels of the cable.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
