At the same time, the chip collection barrel facilitates the centralized processing of cutting chips, thereby improving work efficiency.

It has the advantages of high cutting efficiency, wide cutting range, and easy portability.

[0053] The cutting device has two functions: automatic feed and retract, and automatic cutting. The automatic feed and retract mechanism is an innovative design inspired by the three-jaw chuck.

[0054] This mechanism utilizes the principle of a planetary gear system, where each planetary gear orbiting a central sun gear rotates in the same direction and over the same distance. The meshing of two bevel gears transmits motion, rotating the direction of motion 90 degrees in a plane. When the lead screw and lead nut are mated, if the lead screw nut rotates along a fixed axis and has only one degree of freedom, the lead screw nut will move linearly along the lead screw without rotating.

[0055] In summary, the mechanism realizes the function of automatic advance and retract of the tool.

[0056] This mechanism offers the advantage of higher precision compared to traditional three-jaw chucks. Common three-jaw chucks come in two types. In both types, the forward and backward movement of the clamping mechanism relies on friction between the components. Therefore, compared to three-jaw chucks, this mechanism is less susceptible to wear and has a longer lifespan. Furthermore, when internal parts need to be replaced, since this mechanism has more internal parts than a three-jaw chuck, the replacement parts are generally smaller and less expensive. Furthermore, because this mechanism has more internal space, it is also lightweight.

[0057] The inspiration for the automatic cutting mechanism comes from the form of a lathe driving a three-jaw chuck to rotate. A stepper motor is used to drive the entire knife part of the mechanism to rotate. Gear transmission is used, which has high precision and strong load. BRIEF DESCRIPTION OF THE DRAWINGS

[0095] The first gear 403 drives the first bevel gear to rotate via the rotating shaft. The first bevel gear meshes with the second bevel gear, driving the lead screw 404 to rotate. The nut on the lead screw 404 drives the tool 406 to move axially along the lead screw 404 via the first slider 405, driving the tool 406 to extend or retract from the through hole of the debris collection barrel 402, thereby adjusting the cutting size.

In this embodiment, three connecting rods 215 are preferably provided, evenly distributed on the large gear 205, achieving three-way alignment. Conveyor rollers 214 are also used to convey the cable. In addition to transporting the cable, they also straighten the cable, increasing the feasibility and effectiveness of subsequent processes. Moderate force is sufficient to achieve this function, effectively protecting the cable.

[0101] Further optimizing the solution, the clamping and straightening mechanism 3 includes:

[0102] A fifth stepper motor 301 is mounted on the base 1 via a motor support plate, and a second gear 302 is mounted on the output shaft of the fifth stepper motor 301;

The two clamping bodies 314 are synchronously closed or opened by the first fixed plate 312 and the second fixed plate 313, clamping and releasing the cable.

[0111] The clamping and straightening mechanism 3 is driven by a worm gear, which has a self-locking characteristic and can prevent the device from sliding due to being squeezed by the cable.

[0112] As a further optimization, V-shaped slots 315 are formed on the opposing end surfaces of the two gripper bodies 314. The V-shaped clamp, with its unique geometric shape, has excellent adaptive properties and can automatically adjust its clamping posture according to the actual diameter of the cable, ensuring that the cable is evenly and stably clamped.

[0113] The modular design allows for easy replacement of V-shaped clamps of varying sizes and models, flexibly adapting to a wide range of cable diameters. This enhances the system's versatility and compatibility, allowing for cable clamping and alignment, effectively preventing cable deviation, shaking, or twisting as it enters the cutting mechanism, and providing a stable and reliable baseline for the cutting operation. This significantly improves cutting accuracy and quality while reducing cutting errors and defects caused by cable instability during the cutting process.

[0114] According to a further optimized solution, an aluminum profile and a support plate are installed on the base 1, the second stepper motor 410 is placed on the top surface of the aluminum profile, and the outer wall of the cover 401 is rotatably connected to the top of the support plate.

[0115] As a further optimization solution, a first linear rail 413 is installed on the inner wall of the cover shell 401, and the first slider 405 is slidably connected to the first linear rail 413 to improve the stability of the movement process.
