It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Please combine Figure 1 and Figure 2 As shown, a cable cutting device includes an angle grinder 1, a guide assembly 5, a clamping assembly 3, a feed assembly 4 and a protective shell 2. The angle grinder 1 includes an electric angle grinder 11, a switch 12 and a cutting blade 14. The electric angle grinder 11 drives the cutting blade 14 to rotate. The switch 12 is used to start the electric angle grinder 11. The protective shell 2 is installed on the electric angle grinder 11 through the guide assembly 5 and covers the outer surface of the cutting blade 14. The feed assembly 4 and the clamping assembly 3 are installed on the protective shell 2, and the feed assembly 4 is respectively connected to the clamping assembly 3 and the guide assembly 5, and is used to drive the angle grinder 1 to feed.

[0021] Specifically, the protective shell 2 includes a protective shell body 23 and a protective shell flip cover 21. The protective shell flip cover 21 is hingedly arranged on the protective body 23 to facilitate opening the protective shell 2 to replace the cutting blade 14. The protective shell 2 is designed to be open to facilitate the entry of cables into the protective shell 2.

[0022] Specifically, the clamping assembly 3 includes a clamping ring 33, an open rotating ring 32, a ratchet paddle 34 and an open rotating head 31. The open rotating head 31 is mounted on the protective shell 2. The open rotating ring 32 is fixed on the open rotating head 31. The shapes of the open rotating head 31 and the open rotating ring 32 match the shape of the protective shell 2, so that the cable can enter the clamping assembly 3. The clamping ring 33 is fixed on the open rotating ring 32, and the ratchet paddle 34 is fixed in the clamping ring 33. The clamping ring 33 includes a clamping ring movable piece 331, a clamping ring fixed piece 332 and a clamping bolt 333. The clamping ring fixed piece 332 is fixed on the open rotating ring 32. The clamping ring movable piece 331 is hingedly arranged on the clamping ring fixed piece 332. The clamping bolt 333 passes through the clamping ring fixed piece 332 and is threadedly connected with the clamping ring movable piece 331, thereby fixing the cable in the clamping ring 33.

[0023] Specifically, the guide assembly 5 includes a guide rail 52 and a slide 51 . The guide rail 52 is mounted on the protective shell 2 . The slide 51 is mounted on the angle grinder 11 . The slide 51 is connected to the feed assembly 4 , and the slide 51 moves along the guide rail 52 .

[0024] Specifically, the feed assembly 4 includes a ratchet structure 41, a limit structure 42, a spur gear 43 and a non-return spring pin 44. The spur gear 43 is fixed on the slide 51. The ratchet structure 41 is meshed with the spur gear 43. The limit structure 42 limits the movement distance of the ratchet structure 41. The non-return spring pin 44 abuts against the ratchet structure 41 to prevent the ratchet structure 41 from rotating in the reverse direction. The ratchet structure 41 includes a ratchet 411 and a gear shaft 412. The ratchet 411 is fixed at the end of the gear shaft 412. The ratchet 411 is meshed with the ratchet paddle 34, and the gear shaft 412 is meshed with the spur gear 43. The limiting structure 42 includes a limiting bracket 424, an adjusting screw 422, a limiting plate 423 and an adjusting knob 421. The limiting bracket 424 is provided with a limiting hole 425. The adjusting knob 421 is fixed to the end of the adjusting screw 422. The limiting plate 423 is meshed with the adjusting screw 421. The adjusting screw 422 rotates to drive the limiting plate 423 to move along the limiting hole 425. When the gear shaft 412 touches the limiting plate 423, the electric angle grinder 11 stops moving forward, thereby achieving the goal of controlling the cutting depth as required to meet the cutting requirements.

[0025] Before using the above-mentioned cable cutting device, first operate the adjusting knob 421 according to the cutting depth, so that the adjusting screw 422 rotates to drive the limit plate 423 to move along the limit hole 425, and operate the clamping bolt 333 to loosen it, open the clamping ring movable piece 331 relative to the clamping ring fixed piece 332, and insert the cable into the open rotating ring 32 and the open rotating head 31 so that it enters the clamping ring 33, and the clamping ring movable piece 331 is closed relative to the clamping ring fixed piece 332, operate the clamping bolt 333 to lock, turn on the switch 12, and the angle grinder 1 rotates relative to the cable. After the angle grinder 1 rotates one circle, the ratchet paddle 34 drives the ratchet 411 to rotate one grid, thereby driving the gear shaft 412 to rotate, so as to drive the electric angle grinder 11 to move one grid relative to the protective shell 2, thereby driving the cutting blade 14 to go deeper, thereby realizing cutting of the cable.

[0026] Method 1: Cut a certain length of cable

[0027] According to the length of the cable to be cut, mark the cutting point, open the clamping ring movable piece 331 relative to the clamping ring fixed piece 332, insert the cable into the open rotating ring 32 and the open rotating head 31, so that it enters the clamping ring 33, close the clamping ring movable piece 331 relative to the clamping ring fixed piece 332, operate the clamping bolt 333 to lock until the cable is clamped. Turn on the switch 12, rotate the handle of the electric angle grinder 1, drive the protective shell 2 to rotate, the ratchet paddle 34 to paddle the ratchet 411 to rotate, touch the drive feed ratchet 411 to rotate, and make the cutting blade 14 cut the cable. The electric angle grinder and the protective shell continuously rotate around the cable, and can continuously touch the drive ratchet 411, push the electric angle grinder 11 and the cutting blade 14 to move, and cut the cable until it is cut off. When cutting the cable, different cutting blades need to be used according to the material of the cable.

[0028] Usage method 2: Making steel core aluminum stranded wire crimping terminals

[0029] According to the size and shape of the wire crimping joint, determine the length of the aluminum layer that needs to be stripped, and mark the cutting point. According to the depth of the aluminum layer stripped, operate the adjustment knob 421 to rotate the adjustment screw 422 to drive the limit plate 423 to move along the limit hole 425, and adjust the position of the limit plate 423. Open the clamping ring movable piece 331 relative to the clamping ring fixed piece 332, insert the cable into the open rotating ring 32 and the open rotating head 31, so that it enters the clamping ring 33, and the clamping ring movable piece 331 is closed relative to the clamping ring fixed piece 332, and the clamping bolt 333 is operated to lock, turn on the switch 12, rotate the handle of the electric angle grinder 1, drive the protective shell 2 to rotate, and the ratchet paddle 34 to paddle the ratchet 411 to rotate, and touch the drive feed ratchet 411 to rotate, so that the cutting blade 14 cuts the cable. The electric angle grinder and the protective shell continuously rotate around the wire, and can continuously touch the driving ratchet 411, pushing the electric angle grinder 11 and the cutting blade 14 to move toward the wire, cutting the cable until the cutting depth limit is reached. The cut aluminum layer wire is removed, and the wire crimping connector of the required size can be obtained.
