[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a tube cutting device for automobile wiring harness production with a fixed structure, comprising a bottom support plate 1, both sides of the top end of the bottom support plate 1 are fixedly connected to a support frame 2, a cutting plate 5 is slidably connected to the inner side of the support frame 2, a cutting knife 6 is fixedly connected to the bottom end of the cutting plate 5, an electric push rod 7 is fixedly connected to the inside of the support frame 2, a mounting frame 12 is fixedly connected to the front side of the top end of the bottom support plate 1, a lower pressing roller 10 is rotatably connected to the rear side of the mounting frame 12, a driving motor 14 is fixedly connected to the left side of the rear of the mounting frame 12, and both sides of the top end of the bottom support plate 1 are fixedly connected to the front of the support frame 2. An adjusting rod 15 is installed on the outside of the limiting rod 15. The cutting and pressing assembly is fixedly connected to a cutting and placing table 17 at the rear side of the top end of the bottom support plate 1, and a limited fixing assembly is installed at the rear of the cutting plate 5. The limited fixing assembly includes a support rod 16 located outside the limit rod 15, and the middle part of the inner side of the support rod 16 is rotatably connected to an upper pressing roller 8. Both sides of the mounting frame 12 are rotatably connected to threaded rods 9, and the outer lower sides of the threaded rods 9 are fixedly connected to worm gears 3. The inside of the mounting frame 12 is rotatably connected to a worm 11, and the worm 11 is meshedly connected to the worm gear 3. The left side of the worm 11 is fixedly connected to a handle 13, and the driving end of the driving motor 14 is fixedly connected to the left side of the lower pressing roller 10, and the outer sides of the threaded rods 9 are respectively threadedly connected to the inside of the support rods 16;

[0025] The cable to be cut is placed in the compartment of the lower pressing roller 10. At this time, the handle 13 is rotated to drive the worm 11 to rotate. The outer part of the worm 11 is meshed with the worm wheel 3, thereby driving the threaded rod 9 to rotate. The threaded rods 9 on both sides rotate at the same time. As the outer thread of the threaded rod 9 contacts the support rod 16, the support rod 16 is moved downward, so that the upper pressing roller 8 squeezes and fixes the cable. At this time, the drive motor 14 is started to drive the lower pressing roller 10 to rotate, thereby pulling the cable and moving the cable to the rear side. The cable is located at the top of the cutting and placing table 17. At this time, the electric push rod 7 is started to move the cutting plate 5 downward, and the cutting knife 6 cuts the cable. The pressing rollers on both sides are parallel to each other, and the pressing transmission of the cable is more stable. It can be suitable for cables of various sizes and has a wider applicability.

[0027] When the cutting plate 5 moves downward, the limiting partition 18 limits the cable to prevent the cable from twisting. As the cutting plate 5 is pressed down, the rear pressing plate 19 contacts the top of the cable to fix it, and the force spring 22 rebounds due to the squeezing force of the pressing column 21. The thrust applied by the force spring 22 acts on the surface of the cable, thereby fixing the other side of the cable to prevent the cable on the other side from tilting upward due to the cutting force during cutting, thereby ensuring the quality of cable cutting.

[0028] Working principle: the cable to be cut is placed inside the compartment of the lower pressing roller 10, and the handle 13 is rotated at this time, thereby driving the worm 11 to rotate, thereby driving the threaded rod 9 to rotate, and the threaded rods 9 on both sides rotate at the same time to move the support rod 16 downward, so that the upper pressing roller 8 squeezes and fixes the cable, and at this time, the drive motor 14 is started to drive the lower pressing roller 10 to rotate, thereby pulling the cable and moving the cable to the rear side. The cable is located at the top of the cutting and placing table 17, and the electric push rod 7 is started at this time to move the cutting plate 5 downward, and the cutting knife 6 cuts the cable, and when the cutting plate 5 moves downward, the limiting partition 18 limits the cable, and as the cutting plate 5 is pressed down, the rear pressing plate 19 contacts the top of the cable to fix it, and the force spring 22 rebounds due to the extrusion force of the pressing column 21, and the thrust applied by the force spring 22 acts on the surface of the cable, thereby fixing the other side of the cable cut.
