[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] like Figures 1 to 5 As shown, this utility model provides a controller cable cutting device, including: a cable feeder 1 for feeding controller cables, a cutting structure arranged on one side of the cable feeder 1 for cutting controller cables, and a positioning structure arranged on the cutting structure for pressing down the controller cables.

[0051] The cutting structure includes a support frame 2 arranged on one side of the cable feeder 1, two cutting blades 201 slidably installed inside the support frame 2, and hydraulic rods 202 arranged on both sides of the support frame 2. The output ends of the two hydraulic rods 202 are respectively arranged on the two cutting blades 201. When the hydraulic rods 202 on both sides are opened, the two hydraulic rods 202 push the two cutting blades 201 closer to each other. The two cutting blades 201 that continue to move closer can cut the cable.

[0052] The positioning structure includes a linkage plate 3 arranged on one side of the cutting blade 201, a guide slide rod 301 slidably installed inside the linkage plate 3, a pressure plate 302 arranged at one end of the guide slide rod 301, a rubber strip 303 arranged on one side of the pressure plate 302 for pressing against the surface of the controller cable, and a limiting block 304 arranged at one end of the guide slide rod 301 for preventing the guide slide rod 301 from loosening from inside the linkage plate 3. When the cutting blade 201 moves, it can drive the corresponding linkage plate 3 to move, so that the linkage plate 3 drives the pressure plate 302 to move through the guide slide rod 301. The moving pressure plate 302 can drive the rubber strip 303 to press against the cable.

[0053] The positioning structure also includes a spring 305 arranged between the linkage plate 3 and the pressure plate 302 for pressing the pressure plate 302. The spring 305 is movably sleeved on the guide slide rod 301. The moving pressure plate 302 can drive the rubber strip 303 to press on the cable. At this time, the continuously moving linkage plate 3 will slide on the guide slide rod 301 and compress the spring 305. The force of the spring 305 when it is compressed will act on the pressure plate 302 and the rubber strip 303, so that the rubber strips 303 on both sides can clamp the cable.

[0054] Example 2:

[0055] Based on Example 1, in order to enable the cable to move into the cutting structure in a straight line and prevent the cable from skewing during cutting, a guide structure for guiding the movement of the controller cable is arranged on the cutting structure.

[0056] The guiding structure includes a support rod 4 arranged on one side of the support frame 2, a fixing ring 401 arranged at one end of the support rod 4, several lead screws 402 slidably installed inside the fixing ring 401, an inclined guide bar 403 arranged at one end of the lead screw 402, an adjusting component arranged on the lead screw 402 for adjusting the position of the lead screw 402, and a limiting component arranged on the inclined guide bar 403 for limiting the movement direction of the inclined guide bar 403. The cable feeder 1 is used to feed the controller cable, so that the cable passes through the four inclined guide bars 403 at one end. During the process, the cable will contact the four inclined guide bars 403. At the same time, under the guidance of the inclined surface of the inclined guide bar 403, the cable can be kept in a straight line and pass through the two cutting blades 201.

[0057] Specifically, the adjusting assembly includes a linkage bevel gear ring 404 rotatably mounted on a fixed ring 401 and a driven bevel gear ring 405 threaded onto a lead screw 402. The driven bevel gear ring 405 has a threaded hole inside that matches the lead screw 402. The driven bevel gear ring 405 meshes with the linkage bevel gear ring 404. Rotating the linkage bevel gear ring 404 can drive the driven bevel gear ring 405 to rotate through meshing with the driven bevel gear ring 405. The rotating driven bevel gear ring 405 can drive the lead screw 402 to move through threaded engagement with the lead screw 402. The moving lead screw 402 then drives the inclined guide bar 403 to move.

[0058] Specifically, the adjustment assembly also includes a limiting ring 406 arranged on the outer surface of the fixed ring 401 to limit the rotational position of the driven bevel gear ring 405. The limiting ring 406 is rotatably installed inside the driven bevel gear ring 405. The driven bevel gear ring 405, the limiting ring 406 and the lead screw 402 are all located on the same axis. The rotating driven bevel gear ring 405 can rotate on the limiting ring 406, thereby limiting the position of the driven bevel gear ring 405 when it rotates.

[0059] Specifically, the limiting component includes a linkage slide rod 407 arranged on one side of the inclined guide bar 403, a T-shaped groove 408 opened inside the linkage slide rod 407, and a T-shaped block 409 arranged on one side of the fixing ring 401 to guide the movement direction of the linkage slide rod 407. The T-shaped block 409 is slidably installed in the T-shaped groove 408. When the inclined guide bar 403 moves, it can drive the linkage slide rod 407 to move, so that the linkage slide rod 407 slides on the T-shaped block 409 through the T-shaped groove 408, thereby limiting the movement direction of the linkage slide rod 407 and the inclined guide bar 403.

[0060] Working principle:

[0061] In use, the spacing of the four inclined guide bars 403 is adjusted according to the thickness of the cable. During adjustment, the corresponding linkage bevel gear ring 404 is rotated. When the linkage bevel gear ring 404 rotates, it engages with the driven bevel gear ring 405, causing the driven bevel gear ring 405 to rotate. The rotating driven bevel gear ring 405 rotates on the limit ring 406, thus limiting its position during rotation. The continuously rotating driven bevel gear ring 405 can be engaged with the screw 402 through threaded contact... The lead screw 402 moves, which in turn moves the inclined guide bar 403. The movement of the inclined guide bar 403 causes the linkage slide bar 407 to move, allowing it to slide on the T-block 409 via the T-groove 408. Continuous rotation of the linkage bevel gear ring 404 causes the multiple inclined guide bars 403 to move closer to or further away from each other, thus adjusting the space between the multiple inclined guide bars 403 to match the cable size. The controller cable is then fed using a cable feeder 1, allowing it to pass through four inclined guide bars 403 at one end. During this process, the cable contacts the four inclined guide bars 403, and guided by the inclined surfaces of the guide bars 403, it remains straight as it passes through the two cutting blades 201. When cutting the cable, the hydraulic rods 202 on both sides are activated, causing them to push the two cutting blades 201 closer together. As the cutting blades 201 move, they move the corresponding linkage plate 3, which in turn moves the pressure plate 302 via the guide slide rod 301. The moving pressure plate 302 causes the rubber strip 303 to press against the cable. The continuously moving linkage plate 3 slides on the guide slide rod 301 and compresses the spring 305. The force of the compressed spring 305 acts on the pressure plate 302 and the rubber strip 303, causing the rubber strips 303 on both sides to clamp the cable. The two cutting blades 201, which continue to move closer together, can then cut the cable.

[0062] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
