[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-3As shown, this embodiment proposes a cable cutting device, including a base plate 1, a cable winding and unwinding mechanism 2, a positioning and following mechanism 3, a cutting wheel 4 and an end grinding wheel 5, a first linear moving module 6 is provided on one side above the base plate 1, a second linear moving module 7 is provided on the other side above the base plate 1, a cable winding and unwinding mechanism 2 is installed above the base plate 1 between one end of the first linear moving module 6 and the second linear moving module 7, a positioning and following mechanism 3 is installed on one side of the cable winding and unwinding mechanism 2, and lifting tracks are provided on the side walls of the first linear moving module 6 and the second linear moving module 7. 8. The positioning following mechanism 3 is slidably connected with the lifting track 8. A first adjustable clamping mechanism 9 is provided above the first linear moving module 6. A second adjustable clamping mechanism 10 is provided above the second linear moving module 7. A mounting frame 11 is provided above the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10. A fixing plate 13 is rotatably installed on the mounting frame 11 through a rotating shaft 12. A driving shaft 14 is symmetrically installed on one side of the fixing plate 13. A cutting wheel 4 is installed on one group of the driving shafts 14, and an end grinding wheel 5 is installed on the other group of the driving shafts 14.

[0022] When the cable cutting device of the utility model is used, the cable to be cut is wound and fixed on the cable winding and unwinding mechanism 2, and one end of the cable is pulled out from the bottom of the positioning and following mechanism 3, and then the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 are respectively clamped (in the process, the clamping positions of the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 are kept on the cutting position side of the cutting wheel 4 to prevent the end grinding wheel 5 from grinding the cut cable end so that the cable can be subjected to the clamping support force of the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10, thereby preventing the cable end from being clamped and supported by the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10). The first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 clamp the cable respectively, and the rotating shaft 12 is controlled to rotate, so that the fixing plate 13 is turned over and the cutting wheel 4 installed on one side of the fixing plate 13 first contacts the cable in the clamping range between the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10. The feeding in the cutting process is provided by the synchronous rotation of the fixing plate 13 caused by the rotation of the rotating shaft 12. After cutting, the rotating shaft 12 is continued to be controlled to rotate, so that the end grinding wheel 5 rotates to the position of the cable end after cutting to grind the end surface. When performing the next cutting, first control the cutting wheel 4 and the end grinding wheel 5 to reset, then control the telescopic cylinder 20 on one side to reset, drive the first adjustable clamping mechanism 9 to retract to the position, control the second adjustable clamping mechanism 10 to move forward on the second linear motion module 7, and finally control the first adjustable clamping mechanism 9 to move backward on the first linear motion module 6. After reaching the specified position, control the telescopic cylinder 20 on this side to extend so that the first adjustable clamping mechanism 9 clamps the cable, and then waits for cutting.

[0023] The first linear motion module 6 and the second linear motion module 7 have the same structure, and both include an electromagnetic guide rail 15 and a slide plate 16. The slide plate 16 is slidably provided on the top of the electromagnetic guide rail 15, and the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 are both installed on the slide plate 16. The first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 can be controlled to move by moving the slide plate 16 on the electromagnetic guide rail 15.

[0024] The first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 have the same structure, both of which include an assembly slot 17, a curved clamping plate 18 and a bidirectional screw 19. A telescopic cylinder 20 is installed on the top of the slide 16, and an assembly slot 17 is installed on the output end of the telescopic cylinder 20. A bidirectional screw 19 is rotatably arranged inside the assembly slot 17. A curved clamping plate 18 is symmetrically arranged in a through slot on one side of the assembly slot 17 for sliding. One end of the curved clamping plate 18 is threadedly connected to the bidirectional screw 19. By driving the bidirectional screw 19 to rotate (which can be driven by a motor), the curved clamping plate 18 is relatively moved in the bidirectional screw 19 and the through slot, so that the cable is clamped and fixed inside the two sets of curved clamping plates 18.

[0025] The cable winding and unwinding mechanism 2 includes a bracket 201, a winding roller 202 and a side plate 203. The bracket 201 is provided with a winding roller 202 for rotation inside, and the winding roller 202 is provided with side plates 203 on both sides. The winding roller 202 is driven by an unwinding motor 204 installed on one side of the bracket 201. The cable is unwound by starting the unwinding motor 204 to cooperate with the first adjustable clamping mechanism 9 or the second adjustable clamping mechanism 10 to pull one end of the cable.

[0026] The positioning and following mechanism 3 includes a fixed frame 301, a connecting rod 302 and a positioning and following guide roller 303. The connecting rod 302 is provided on both sides of the fixed frame 301. One end of the connecting rod 302 is slidably connected to the lifting track 8. The positioning and following guide roller 303 is rotatably installed inside the fixed frame 301. The length of the positioning and following guide roller 303 is more than twice the length of the cable diameter. By setting the positioning and following mechanism 3, when the position height of the cable wound on the cable winding and unwinding mechanism 2 is the center height of the clamping range of the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10, in order to ensure smooth clamping of the cable, the center height of the positioning and following guide roller 303 can be adjusted to the same height as the center height of the clamping range of the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10, so that the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 can smoothly clamp the cable.

[0027] The rotating shaft 12 is driven by a first driving motor 21 , and the driving shaft 14 is driven by a second driving motor 22 .

[0028] The utility model symmetrically arranges the cutting wheel 4 for cutting and the end grinding wheel 5 for grinding on the fixed plate 13 driven to rotate by the rotating shaft 12, so that the cutting wheel 4 can be used to cut the cable first by driving the fixed plate 13, and then the end grinding wheel 5 after the cutting wheel 4 is rotated to grind the cable end after the cutting, so that the cut surface of the cable after cutting is smooth and burr-free, which effectively improves the quality of the cut cable, and the cut cable and the cable accessories can be closely overlapped and avoid the formation of tip discharge phenomenon, so that the use safety of the cut cable is improved; the utility model The first linear moving module 6 and the second linear moving module 7 are arranged to respectively drive the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10, so that the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10 can automatically clamp one end of the cable to wait for the cutting operation. During the process, there is no need to manually pull the cable, so that the efficiency and safety of the cutting operation are improved; the positioning following mechanism 3 can ensure that the cable unwound from the cable winding and unwinding mechanism 2 is always in a concentric state with the clamping range of the first adjustable clamping mechanism 9 and the second adjustable clamping mechanism 10, thereby ensuring the efficient implementation of the clamping and cutting operations.
