[0002] A cable is usually a rope-like cable formed by stranding several or several groups of wires. Each group of wires is insulated from each other, often twisted around a center and covered with a highly insulating covering layer on the outside. The cable has the characteristics of being energized inside and insulated outside. During the construction of a power cable renovation project, cables of different lengths are usually required, so it is necessary to cut the cable to a fixed length.

[0003] In the prior art, when cutting a cable, it is usually the staff who holds the cable by hand and then cuts the cable with a guillotine. This cutting method is not only unsafe, but also has a large cutting error, low processing efficiency, and consumes a lot of manpower and material resources. Summary of the Invention

[0006] By adopting the above technical solutions, when cutting and processing the cable, the cable is laid on the base, and one end of the cable is passed through the cutting frame and inserted into the clamping seat, so that the end of the cable abuts against the inner wall of the groove, and the cable is pressed and fixed by the pressing mechanism arranged in the groove. When cutting the cable to a fixed length, the driving mechanism drives the clamping seat to move, and the cutting length of the cable is adjusted by adjusting the distance between the clamping seat and the cutting frame. After the cutting length of the cable is adjusted, the first cylinder is started to drive the cutter to move down to cut the cable, conveniently realizing the fixed-length cutting of the cable, and reducing the trouble of manual cable cutting, which is time-consuming and laborious and has a large cutting error.

[0007] Preferably, the driving mechanism includes a lead screw and a motor; the lead screw is rotatably connected to the top surface of the base, and the lead screw is arranged along the moving direction of the clamping seat and penetrates through the clamping seat; the clamping seat is in threaded driving cooperation with the lead screw; the motor is installed on the top surface of the base, and a driving shaft is coaxially fixed to the output end of the motor; a first bevel gear is coaxially fixed to the end of the driving shaft away from the motor; a second bevel gear meshing with the first bevel gear is coaxially fixed to the outer wall of the lead screw close to the driving shaft.

[0008] By adopting the above technical solution, when the motor is started to drive the driving shaft and the first bevel gear to rotate, under the meshing cooperation of the first bevel gear and the second bevel gear, the driving shaft drives the lead screw to rotate, prompting the clamping seat to slide along the axial direction of the lead screw and pull the cable to move, realizing the adjustment of the distance between the clamping seat and the cutting frame, so as to cut the cable to a fixed length according to actual needs.

[0011] Preferably, a rubber pad is fixed to the bottom surface of the pressing plate.

[0018] By adopting the above technical solution, the cable is passed through the sleeve, so that the outer wall of the cable contacts the bristles. During the process that the lead screw rotates to drive the clamping seat to pull the cable to move, the lead screw drives the sleeve to move through the second transmission assembly, so that the bristles arranged on the inner circumferential surface of the sleeve clean the outer wall of the moving cable, removing impurities and stains on the outer wall of the cable, keeping the cut cable clean, and reducing the possibility of the impurities affecting the cutter and causing cutting wear.

[0029] The present invention discloses a cutting device for cable processing, as shown in Figure 1 and Figure 2 , which includes a base 1, a cutting frame 2, a clamping seat 3 and a driving mechanism 4. The cutting frame 2 is vertically fixed on the top surface of the base 1. There is a through hole on the cutting frame 2 for the cable to pass through. A pair of first cylinders 21 are vertically installed on the top surface of the cutting frame 2. The output ends of the two first cylinders 21 are fixed with the same cutter 22. The cutter 22 is located in the through hole. The clamping seat 3 is slidably installed on the top surface of the base 1 on one side of the cutting frame 2. The end of the cable can be clamped and installed on the side wall of the clamping seat 3 close to the cutting frame 2. The driving mechanism 4 is arranged on the top surface of the base 1. The driving mechanism 4 can drive the clamping seat 3 to move to adjust the distance between the clamping seat 3 and the cutting frame 2.

[0030] Lay the cable on the base 1, pass one end of the cable through the cutting frame 2 and clamp it on the clamping seat 3. Drive the clamping seat 3 to move through the driving mechanism 4, and adjust the distance between the clamping seat 3 and the cutting frame 2 to realize the adjustment of the cutting length of the cable. After the cutting length of the cable is adjusted, start the first cylinder 21 to drive the cutter 22 to move down to cut the cable, which can conveniently realize the fixed-length cutting of the cable, and reduce the trouble of manual cable cutting that is time-consuming, laborious and has large cutting errors.

[0031] As Figure 1 and Figure 3 shown, the driving mechanism 4 includes a lead screw 41, a motor 42, a first bevel gear 43 and a second bevel gear 44; the lead screw 41 is horizontally rotatably connected to the top surface of the base 1, the lead screw 41 is arranged along the sliding direction of the clamping seat 3 and penetrates through the clamping seat 3, the clamping seat 3 is in threaded transmission cooperation with the lead screw 41, the motor 42 is horizontally installed on the top surface of the base 1, the output end of the motor 42 is coaxially fixed with a driving shaft 421, the first bevel gear 43 is coaxially fixed on the outer wall of the end of the driving shaft 421 away from the motor 42, the second bevel gear 44 is coaxially fixed on the outer wall of the end of the lead screw 41 close to the driving shaft 421, and the second bevel gear 44 meshes with the first bevel gear 43.

[0032] Start the motor 42 to drive the driving shaft 421 and the first bevel gear 43 to rotate. Under the meshing cooperation of the first bevel gear 43 and the second bevel gear 44, the driving shaft 421 drives the lead screw 41 to rotate, prompting the clamping seat 3 to slide along the axial direction of the lead screw 41 and pull the cable to move, realizing the adjustment of the distance between the clamping seat 3 and the cutting frame 2, so as to adjust the cutting length of the cable as needed.

[0033] As Figure 1 and Figure 4 shown, a groove 31 for the cable to be inserted is formed on the side wall of the clamping seat 3 close to the cutting frame 2, and a pressing mechanism 32 for pressing and fixing the cable is arranged in the groove 31. The pressing mechanism 32 includes a second cylinder 321 and a pressing plate 322. The second cylinder 321 is vertically installed on the top surface of the clamping seat 3, the output end of the second cylinder 321 extends into the groove 31, the pressing plate 322 is fixed to the output end of the second cylinder 321, the bottom end of the pressing plate 322 is concave, and a rubber pad 323 is fixed to the bottom surface of the pressing plate 322.

[0034] Insert one end of the cable into the groove 31 so that the end of the cable abuts against the vertical inner wall of the groove 31. Start the second cylinder 321 to drive the pressing plate 322 to move down to press the cable, so as to prompt the clamping seat 3 to be able to pull the cable to move during the movement. The setting of the rubber pad 323 increases the friction force at the contact part between the pressing plate 322 and the cable, and improves the pressing and fixing effect of the pressing plate 322.

[0035] As Figure 1and Figure 4 As shown in Figure 4 , a scale 11 arranged along the axial direction of the lead screw 41 is fixedly connected to the top surface of the base 1. The starting scale position of the scale 11 corresponds to and is flush with the cutting position of the cutting tool 22. A laser indicator 33 that points obliquely downward to the scale 11 is provided on the outer wall of the clamping seat 3 close to the scale 11. The position where the laser indicator 33 indicates the scale corresponds to and is flush with the position where the end face of the cable contacts the inner wall of the groove 31.

[0036] When the clamping seat 3 drives the cable to move, the cooperation of the laser indicator 33 and the scale 11 can visually display the distance from the end of the cable to the cutting position of the cutting tool 22, facilitating the staff to observe the moving distance of the cable, so as to more accurately adjust the cutting length of the cable.

[0037] As Figure 1 and Figure 5 As shown in Figure 5 , a first support frame 5 is fixedly connected to the top surface of the base 1 on the side of the cutting frame 2 away from the clamping seat 3. A plurality of support rollers 51 arranged at intervals are horizontally rotatably connected to the inner wall of the first support frame 5. The support rollers 51 are arranged coaxially with the driving shaft 421. The tops of the plurality of support rollers 51 are at the same height as the bottom surface of the groove 31. A first transmission component 52 for enabling the driving shaft 421 to drive the plurality of support rollers 51 to rotate synchronously is provided on the outer wall of the driving shaft 421; The first transmission component 52 includes a first sprocket 521, a plurality of second sprockets 522 and a chain 523. The first sprocket 521 is coaxially fixedly connected to the outer wall of the driving shaft 421. The plurality of second sprockets 522 are respectively coaxially fixedly connected to the outer walls of the ends of the plurality of support rollers 51 close to the motor 42. The chain 523 is sleeved outside the first sprocket 521 and the plurality of second sprockets 522, and the chain 523 links the first sprocket 521 and the plurality of second sprockets 522.

[0038] When the driving shaft 421 rotates to cause the clamping seat 3 to pull the cable to move, the driving shaft 421 drives the plurality of support rollers 51 to rotate through the cooperation of the first sprocket 521, the plurality of second sprockets 522 and the chain 523, thereby reducing the moving resistance of the cable laid on the support rollers 51 and reducing the possibility of the cable falling off from the clamping seat 3 due to a large resistance.

[0039] As Figure 1 and Figure 6 As shown in Figure 6 , a cleaning frame 6 is vertically fixedly connected to the top surface of the base 1 between the first support frame 5 and the cutting frame 2. A sleeve 61 through which the cable can pass is horizontally rotatably connected to the cleaning frame 6. The sleeve 61 is coaxial with the lead screw 41. One end of the sleeve 61 extends outside the cleaning frame 6. Brush hairs 62 that can contact the outer wall of the cable are provided on the inner peripheral surface of the sleeve 61. A second transmission component 63 for enabling the lead screw 41 to drive the sleeve 61 to rotate is provided on the outer wall of the cleaning frame 6; The second transmission component 63 includes a spur gear 631, a gear ring 632, a first pulley 634, a second pulley 635 and a belt 636. The spur gear 631 is rotatably connected to the outer wall of the cleaning frame 6 through a rotating shaft 633. The gear ring 632 is coaxially fixed to the outer peripheral surface of the sleeve 61 extending outside the cleaning frame 6. The gear ring 632 meshes with the spur gear 631. The first pulley 634 is coaxially fixed to the outer wall of the lead screw 41 near one end of the rotating shaft 633. The second pulley 635 is coaxially fixed to the outer wall of the rotating shaft 633. The belt 636 is tensioned and sleeved outside the first pulley 634 and the second pulley 635. The belt 636 enables the first pulley 634 and the second pulley 635 to be linked.

[0040] Thread the cable through the sleeve 61 to make the cable contact the bristles 62. When the lead screw 41 rotates to drive the clamping seat 3 to pull the cable to move, the lead screw 41 drives the rotating shaft 633 to rotate through the cooperation of the first pulley 634, the second pulley 635 and the belt 636. Then, through the meshing cooperation of the spur gear 631 and the gear ring 632, the rotating shaft 633 drives the sleeve 61 to rotate, prompting the bristles 62 to clean the outer wall of the moving cable, removing impurities on the cable, keeping the surface of the cut cable clean, and reducing the possibility of the cutter 22 being worn by hard impurities.

[0041] As Figure 1 and Figure 7 shown, a second support frame 7 is fixedly connected to the top surface of the base 1 and is located between the cleaning frame 6 and the cutting frame 2. A plurality of straightening rollers 71 coaxial with the support rollers 51 are horizontally rotatably connected to the inner wall of the second support frame 7. The outer peripheral surfaces of the plurality of straightening rollers 71 cooperate to form a straightening channel for the cable to pass through and match the cable. The plurality of straightening rollers 71 are arranged at staggered intervals in the axial direction of the cable and are arranged on the upper and lower sides of the cable.

[0042] When the cable is cut, thread the cable through the straightening channel. When the clamping seat 3 pulls the cable to move, the straightening rollers 71 straighten the cable, reducing the large degree of bending of the cable during cutting and improving the cutting accuracy.

[0043] Working principle: When the cable is cut, lay one end of the cable on the support roller 51 of the first support frame 5, and thread the other end of the cable through the sleeve 61, the straightening channel and the cutting frame 2 in sequence and then insert it into the groove 31 of the clamping seat 3, so that the end of the cable abuts against the inner wall of the groove 31. Start the second cylinder 321 to drive the pressing plate 322 to move down to press the end of the cable, realizing the clamping and installation of the end of the cable on the clamping seat 3; When it is necessary to adjust the cutting length of the cable, start the motor 42 to drive the drive shaft 421 to rotate. Under the meshing cooperation of the first bevel gear 43 and the second bevel gear 44, the drive shaft 421 drives the lead screw 41 to rotate, prompting the clamping seat 3 to move along the axial direction of the lead screw 41 and pulling the cable to move, so as to adjust the distance from the end of the cable to the cutting position. When the clamping seat 3 moves to a suitable position, start the first cylinder 21 to drive the cutter 22 to move down to cut the cable to achieve fixed-length cutting of the cable; When the cable is pulled through the straightening channel, the straightening wheels will straighten the moving cable, prompting the cable to remain straight, reducing the possibility that the cable bends to a large extent when adjusting the cutting length of the cable, and improving the cutting accuracy of the cable; During the process of the drive shaft 421 rotating to prompt the clamping seat 3 to move, the drive shaft 421 will drive a plurality of support rollers 51 to rotate through the first transmission assembly 52, reducing the frictional resistance between the cable and the support rollers 51 during the pulling process, facilitating the clamping seat 3 to pull the cable to move, and reducing the possibility that the cable falls off the clamping seat 3 due to excessive resistance; During the rotation of the lead screw 41, it will drive the sleeve 61 to rotate through the second transmission assembly 63, prompting the bristles 62 provided on the inner peripheral surface of the sleeve 61 to clean the outer wall of the moving cable, reducing the possibility that hard impurities adhere to the outer wall of the cable, prompting the cut cable to remain clean, and reducing the possibility that the hard impurities cause wear of the cutter 22 during the cutting of the cutter 22.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
