[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Figure 1 A schematic structural diagram of a low-friction cable ring cutting machine in the present invention is shown, wherein the low-friction cable ring cutting machine comprises: a driving device 100 and a ring cutting device 200, wherein the driving device 100 is used to drive the cable to be processed to rotate or feed forward, and the ring cutting device 200 is used to cut the cable to be processed.

[0032] Figure 2 The schematic diagram of the structure of the ring cutting device 200 in the present invention is shown. The ring cutting device 200 includes: a C-shaped rotating tool 3 and a C-shaped fixed frame 4. The C-shaped rotating tool 3 is mounted on the C-shaped fixed frame 4. The C-shaped rotating tool 3 is driven by the first drive motor 6 to rotate. The C-shaped rotating frame is used to place the C-shaped rotating tool 3, and the C-shaped ring cutting tool is used to cut cables. The position where the C-shaped rotating tool 3 is placed on the rotating frame is also provided with a C-shaped placement area. When not in operation, the opening of the C-shaped rotating tool 3 coincides with the opening of the C-shaped placement area to facilitate the insertion of the cable into the corresponding position.

[0033] Furthermore, the C-shaped rotary cutter 3 includes a C-shaped gear 31 and a blade 32, wherein the blade 32 is embedded in the C-shaped gear 31; the C-shaped gear 31 has protrusions on both sides forming limiting bosses 33, which are connected to the rotating frame based on multiple bearings 5. The blade 32 is used to cut the cable, and the C-shaped gear 31 drives the blade 32 to rotate, thereby processing the surface of the cable. In this embodiment, the limiting bosses 33 are connected to the rotating frame based on thirty bearings 5, of which fifteen bearings 5 ​​abut against the limiting bosses 33 raised on one side of the C-shaped gear 31, and the remaining fifteen bearings 5 ​​abut against the limiting bosses 33 raised on the other side of the C-shaped gear 31. The thirty bearings 5 ​​are used to reduce friction between the C-shaped gear 31 and the rotating frame, improve the smoothness of the rotation of the C-shaped gear 31, and extend the service life of the C-shaped gear 31. Moreover, the thirty bearings 5 ​​abut against the limiting boss 33, which can limit the position of the C-shaped gear 31 on the rotating frame, thereby preventing the C-shaped rotating tool 3 from being detached during use, thereby improving the safety of the low-friction cable cutting machine.

[0034] Furthermore, a first drive motor 6 is provided on one side of the C-shaped fixing frame 4, and the C-shaped gear 31 is driven to rotate by the first drive motor 6. A driving gear is provided on the output end of the first drive motor 6, and two driven gears are provided above the driving gear. The distance between the two driven gears is larger than the opening of the C-shaped gear 31, so that the C-shaped gear 31 is meshed with at least one of the driven gears, ensuring that the first drive motor 6 can drive the driving gear to rotate, so that the driving gear drives the driven gear to rotate, and then the driven gear drives the C-shaped gear 31 to rotate, which is beneficial to improving the stability of the low-friction circular cable cutting machine.

[0035] The driving device 100 includes a rotating mechanism 1 and a moving mechanism 2. The rotating mechanism 1 is connected to the moving mechanism 2 based on the circular cutting device 200. That is, the circular cutting device 200 is located between the rotating mechanism 1 and the moving mechanism 2, and one side of the circular cutting device 200 is connected to the rotating mechanism 1, and the other side of the circular cutting device 200 is connected to the moving mechanism 2. The rotating mechanism 1 is used to drive the cable to be processed to rotate about its axis to facilitate cutting; the moving mechanism 2 is used to drive the cable to be processed forward to facilitate cutting; the rotating mechanism 1 and the moving mechanism 2 cooperate with each other to cause the cable to be processed to advance in a spiral manner.

[0036] Figure 3 It shows the structural diagram of the rotating mechanism 1 in the present invention. Figure 4 A cross-sectional view of the first limit block 111 of the present invention is shown. The rotation mechanism 1 includes: a first fixed seat 11 and a first lifting seat 12. The first fixed seat 11 is provided with one or more first limit blocks 111. Each of the first limit blocks 111 is mounted with a plurality of first rotating balls 112, which are distributed on the first fixed seat 11. The first lifting seat 12 is provided with a plurality of first pulleys 121. In this embodiment, the first fixed seat 11 is provided with two first limit blocks 111, each of the first limit blocks 111 is mounted with six first rotating balls 112, and the first lifting seat 12 is provided with five first pulleys 121. The five first pulleys 121 are used to drive the cable to rotate. The first balls are used to reduce friction between the cable and the rotation mechanism 1, preventing the cable from getting stuck during feeding and reducing the time required for repeated processing during cable feeding.

[0037] Furthermore, the middle area of ​​any of the first limiting blocks 111 is recessed downward to form a first arc surface, and a plurality of first connection holes 113 are provided on the first arc surface, and a plurality of first rotating balls 112 are inserted into the corresponding first connection holes 113. The arc surface conforms to the outer surface of the cable to be processed, and six first connection holes 113 are provided on the first arc surface, wherein the six first rotating balls 112 correspond to one of the six first connection holes 113, that is, the first connection holes 113 and the first rotating balls 112 have a one-to-one correspondence. The depth at which the first rotating ball 112 is installed in the first connection hole 113 is greater than the radius of the first rotating ball 112, thereby preventing the first rotating ball 112 from falling off during rotation, which helps to ensure that the first rotating ball 112 maintains contact with the cable surface.

[0038] Furthermore, a first buffer mechanism 114 is provided in each of the first connection holes 113. Each of the buffer mechanisms includes a first connection block 1141 and a first spring 1142. The first connection block 1141 is located below the first rotating sphere 112, and the first spring 1142 is connected to the first rotating sphere 112 based on the first connection block 1141. One end of the first spring 1142 is connected to the first connection block 1141, and the other end of the first spring 1142 is connected to the bottom of the first connection hole 113. When the cable is placed on the first limiting block 111, the cable exerts pressure on the first rotating sphere 112, causing the first rotating sphere 112 to move toward the bottom of its corresponding first connection hole 113, thereby compressing the first spring 1142. After the first spring 1142 is compressed, a reaction force is exerted on the corresponding first rotating sphere 112, so that the first rotating sphere 112 exerts an axial force on the geometric center of the cable, so that the surface of the first rotating sphere 112 fits the surface of the cable, thereby fixing the position of the cable on the first limit block 111, avoiding the risk of offset during processing, and improving the processing accuracy of the low-friction circular cable cutting machine.

[0039] Figure 5 It shows the structural diagram of the moving mechanism 2 in the present utility model. Figure 6A cross-sectional view of the second limit block 211 of the present invention is shown. The moving mechanism 2 includes: a second fixed seat 21 and a second lifting seat 22. The second fixed seat 21 is provided with one or more second limit blocks 211. Each second limit block 211 is mounted with multiple second rotating balls 212, which are distributed on the second fixed seat 21. The second lifting seat 22 is provided with multiple second pulleys 221. In this embodiment, the second fixed seat 21 is provided with two second limit blocks 211, each second limit block 211 is mounted with six second rotating balls 212, and the second lifting seat 22 is provided with twenty-four second pulleys 221, which are used to drive the cable feed. The second balls are used to reduce friction between the cable and the rotating mechanism 1, preventing the cable from getting stuck during the feed process and reducing the time required for repeated processing during the cable feed process.

[0040] Furthermore, a second limiting block 211 is provided on the second fixing seat 21. The middle area of ​​the second limiting block 211 is recessed downward to form a second arc surface, and a plurality of second connection holes 213 are provided on the arc surface. A plurality of second rotating balls 212 are inserted into the corresponding second connection holes 213. The second arc surface fits the outer surface of the cable to be processed. Six second connection holes 213 are provided on the second arc surface, wherein the six second rotating balls 212 correspond to one of the six second connection holes 213, that is, the second connection holes 213 and the second rotating balls 212 correspond one to one. The depth of the second rotating ball 212 installed in the second connection hole 213 is greater than the radius of the second rotating ball 212, which prevents the second rotating ball 212 from falling off during rotation, and helps to ensure that the second rotating ball 212 maintains contact with the cable surface.

[0041] Furthermore, a second buffer mechanism 214 is provided in each of the second connection holes 213. Each of the buffer mechanisms includes a second connection block 2141 and a second spring 2142. The second connection block 2141 is located below the second rotating sphere 212, and the second spring 2142 is connected to the second rotating sphere 212 based on the second connection block 2141. One end of the second spring 2142 is connected to the second connection block 2141, and the other end of the second spring 2142 is connected to the bottom of the second connection hole 213. When the cable is placed on the second limiting block 211, the cable exerts pressure on the second rotating sphere 212, causing the second rotating sphere 212 to move toward the bottom of its corresponding second connection hole 213, thereby compressing the second spring 2142. After the second spring 2142 is compressed, a reaction force is exerted on the corresponding second rotating sphere 212, so that the second rotating sphere 212 exerts an axial force on the geometric center of the cable, so that the surface of the second rotating sphere 212 fits the surface of the cable, thereby fixing the position of the cable on the second limit block 211, avoiding the risk of offset during processing, and improving the processing accuracy of the low-friction circular cutting cable machine.

[0042] Furthermore, a first height adjustment rod is inserted into the first limit block 111, and the first limit block 111 is connected to the first fixing seat 11 based on the first height adjustment rod. The first height adjustment rod is used to adjust the position of the first limit block 111 on the first fixing seat 11 so that the first limit block 111 can fit the surface of the cable to be processed; similarly, a second height adjustment rod is inserted into the second limit block 211, and the second limit block 211 is connected to the second fixing seat 21 based on the second height adjustment rod. The second height adjustment rod is used to adjust the position of the second limit block 211 on the second fixing seat 21 so that the second limit block 211 can fit the surface of the cable to be processed. The first height adjustment rod and the second height adjustment rod ensure that the first limit block 111 and the second limit block 211 are on the same horizontal plane, ensuring that the low-friction cable cutting machine can clamp the cable to be processed, reducing the phenomenon of one end of the cable being higher than the other end during processing, and helping to improve the processing accuracy of the low-friction cable cutting machine.

[0043] Furthermore, the first rotating sphere 112 is a hollow sphere, and the second rotating sphere 212 is a hollow sphere. Both the first rotating sphere 112 and the second rotating sphere 212 are hollow spheres. Hollow spheres are much lighter than solid spheres of the same volume, effectively reducing the weight of the low-friction cable cutting machine and facilitating the user's transport of the low-friction cable cutting machine to other work locations. Furthermore, the light weight of the hollow spheres facilitates quick replacement by maintenance personnel, reducing the maintenance time of the low-friction cable cutting machine.

[0044] To sum up, the utility model sets a first rotating sphere and a second rotating sphere, and the first rotating sphere and the second rotating sphere can rotate in any direction, which is beneficial to reducing the friction between the cable and the rotating mechanism, avoiding the cable from getting stuck during the feeding process, and reducing the time of repeated processing during the cable feeding process.
