DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 A cable cutting device in this embodiment includes a workbench 1, a cutting table 2 is fixed at the center of the top surface of the workbench 1, a support frame 3 is fixed to the top surface of the workbench 1, electric push rods 4 are fixedly installed on the left and right sides of the top wall of the support frame 3, a mounting plate 5 is fixed to the bottom ends of the two electric push rods 4, a guillotine 6 is provided just below the mounting plate 5, and a disassembly mechanism 7 is provided on the guillotine 6.

[0024] See also Figure 1-3 In order to facilitate the replacement or maintenance of the guillotine 6, the disassembly and assembly mechanism 7 includes a driving assembly arranged on the mounting plate 5, a disassembly and assembly assembly arranged on the driving assembly, and a limit assembly arranged on the disassembly and assembly assembly.

[0025] Among them, the top surface of the cutting table 2 is provided with arc grooves 8 distributed front to back, which is convenient for placing cables. The center of the top surface of the cutting table 2 is provided with a cutting groove 9 distributed left to right and connected to the arc groove 8. The guillotine 6 can be inserted into the cutting groove 9 to cut the cable.

[0026] At the same time, the driving assembly includes a fixed plate 701 fixed on the left and right sides of the bottom surface of the mounting plate 5, a threaded rod 702 rotatably connected between the opposite sides of the two fixed plates 701 through a bearing, and a driven bevel gear 703 fixed at the middle position of the outer surface of the threaded rod 702. The driving assembly also includes a rotating rod 705 rotatably connected to the center of the top surface of the mounting plate 5 through a bearing, an active bevel gear 704 fixed at the bottom end of the rotating rod 705 and meshing with the driven bevel gear 703, and a turning handle 706 fixed at the top end of the rotating rod 705. The driving assembly utilizes the rotation of the rotating rod 705 and the cooperation of the active bevel gear 704 and the driven bevel gear 703 to make the threaded rod 702 rotate forward and reverse.

[0027] In addition, the threads on the outer surface of the threaded rod 702 are in opposite directions, and the rotating rod 705 extends to the top of the mounting plate 5, so that the rotating rod 705 can be driven to rotate by the turning handle 706.

[0028] In addition, the disassembly and assembly component includes a movable plate 707 threadedly connected to the left and right sides of the outer surface of the threaded rod 702, the disassembly and assembly component also includes a fixed seat 708 fixed on the left and right sides of the top surface of the guillotine 6, and a limiting groove 709 opened on the opposite side of the two fixed seats 708. The disassembly and assembly component also includes a fixed box 710 fixed on the left and right sides of the bottom surface of the mounting plate 5 and respectively located directly above the two fixed seats 708, and a limiting rod 711 fixed to the bottom end of the opposite side of the two movable plates 707. The disassembly and assembly component mainly realizes the fixing and disassembly process of the guillotine 6 by using the limiting rod 711 in conjunction with the limiting groove 709, and the operation is simple and convenient.

[0029] It should be noted that threaded holes are provided on the sides of the two movable plates 707, and the left and right sides of the outer surface of the threaded rod 702 respectively penetrate the two threaded holes and are threadedly connected thereto. When the threaded rod 702 rotates forwards and backwards, it can drive the two movable plates 707 to move to the opposite side or the back side.

[0030] It can be understood that the two fixed seats 708 extend from the bottom ends of the two fixed boxes 710 to the interior of the fixed boxes 710 respectively, and the opposite ends of the two limit rods 711 extend into the two limit grooves 709 respectively and cooperate with the gaps therewith. The limit rods 711 are inserted into the limit grooves 709 to achieve the limiting effect on the fixed seats 708. When the limit rods 711 are pulled out of the limit grooves 709, the disassembly process of the guillotine 6 can be realized.

[0031] Finally, the limiting assembly includes a slider 712 fixed on the top of the two movable plates 707, and the limiting assembly also includes a slide groove 713 opened on the left and right sides of the bottom surface of the mounting plate 5 and respectively for the two sliders 712 to be inserted into and slidably connected with them. The coordinated use of the slider 712 and the slide groove 713 can improve the stability of the movable plate 707 during the movement process.

[0032] The working principle of the above embodiment is:

[0033] When cutting the cable, first place the cable in the arc groove 8 on the top surface of the cutting table 2, then start the electric push rod 4, and drive the guillotine 6 to move downward under the action of the electric push rod 4, and insert the guillotine 6 into the cutting groove 9 on the cutting table 2 to cut the cable. When the guillotine 6 is blunted or damaged after long-term use, it can be replaced or maintained. Specifically, the rotating rod 705 is rotated by the turning handle 706, and the active bevel gear 704 is further driven to rotate by the rotating rod 705. The active bevel gear 704 drives the driven bevel gear 703 to rotate during the rotation process, and further drives the threaded rod 702 to rotate. The threaded rod 702 is rotated during the rotation process. The two movable plates 707 are driven to move to the opposite side. During the movement, the limiting rod 711 is pulled out from the limiting groove 709 on the fixed seat 708. At this time, the guillotine 6 can be pulled downward until the fixed seat 708 is completely pulled out of the fixed box 710. During installation, it is only necessary to push the guillotine 6 upward and insert the fixed seat 708 into the fixed box 710 from the bottom, and then rotate the rotating rod 705 in the opposite direction through the turning handle 706. At this time, the threaded rod 702 rotates in the opposite direction, and drives the two movable plates 707 to move to the opposite side, and pushes the limiting rod 711 to be inserted into the limiting groove 709 to complete the installation process.

[0034] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
