Description

Technical Field

[0001] The invention relates to the technical field of cable cutting, in particular to a cable positioning and cutting device. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cable is a wire product used to transmit electrical (magnetic) energy, information and complete electromagnetic energy conversion. It is mainly used for multiple functions such as control installation, connecting equipment, and transmitting electricity. During the use of cables, the cables need to be cut to a certain length to meet the different usage requirements of the cables.

[0003] The utility model patent with authorization announcement number CN202121485331.0 discloses a cable shearing device for electric power engineering, which includes a base, a bracket fixedly installed on the top of the base, a motor fixedly installed on the top of the bracket, the output shaft of the motor extends into the bracket and is fixedly installed with a first bevel gear, first threaded rods are rotatably installed on the inner walls of both sides of the bracket, and the ends of the two first threaded rods close to each other are fixedly installed with second bevel gears, the first bevel gears are meshed with the two second bevel gears, and the outer sides of the two first threaded rods are threadedly sleeved with movable plates, and the sides of the two movable plates away from each other are fixedly installed with fixed plates, and the inner sides of the two fixed plates are threadedly connected with second threaded rods, and the bottom ends of the two second threaded rods are rotatably installed with bottom plates, and the sides of the two bottom plates close to each other are fixedly installed with arc pressure plates, and circular holes are opened on one side of the two movable plates, and the two arc pressure plates are located in the corresponding circular holes. A cylinder is fixedly installed in the bracket, and a cutter is fixedly connected to the piston shaft of the cylinder. By rotating the two second threaded rods, the two arc-shaped pressure plates can be driven to move downward through the two bottom plates to press the cable and fix the cable, and the motor can be started. Through the meshing transmission of the first bevel gear and the two second bevel gears, and the threaded connection between the two moving plates and the corresponding first threaded rods, the two moving plates can be moved away from each other, and then the two moving plates can straighten the cable, thereby ensuring that the cut of the cable is smooth during shearing and the shearing effect is good.

[0004] Although the cable cutting device for power engineering has the advantage of good cutting effect, the device still has the following problems in actual use: when the device is cutting the cable, the cable worker needs to manually place the cable under the cutter.

[0046] It should be added that, in the present embodiment, the thread winding directions of the two ends of the first double-ended screw 21 and the second double-ended screw 36 are opposite. When the first double-ended screw 21 rotates, the movable plates 24 on both sides can move relative to each other synchronously, and the movable plates 24 drive the mounting frame 25 to move relative to each other, thereby facilitating the adjustment of the spacing between the two conveyor belts 27 to transport cables of different sizes; when the second double-ended screw 36 rotates, the clamping blocks 37 on both sides move relative to each other synchronously, thereby driving the clamping grooves 370 to clamp and fix the cables.

[0047] It is worth noting that the first motor 23 and the second motor 39 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0048] During specific use, the user first passes the end of the cable through between the two rollers 11 located on the rear side, and places the cable between the two conveyor belts 27. At the same time, the user turns on the power of the electric roller 26, and the electric roller 26 drives the conveyor belt 27 to move, and the conveyor belt 27 drives the cable to move horizontally to the front side. At this time, the user guides the front end of the cable to pass between the two rollers 11 located on the front side, and guides the front end of the cable to pass through the cable groove 300. When the cable moves to the appropriate position, the user stops the power of the electric roller 26, and then the user turns on the power of the second motor 39. The second motor 39 starts to work, the output shaft of the second motor 39 rotates to drive the second double-headed screw 36 and the pulley 360 to rotate, and under the drive of the belt 361, the two second double-headed screws 36 rotate synchronously. At this time, the clamping blocks 37 on both sides move synchronously toward the middle. When the clamping groove 370 clamps the cable, the cable is fixed. The user stops the power supply of the second motor 39, and then the user turns on the power supply of the electric cylinder 32. The piston rod of the electric cylinder 32 extends and drives the connecting plate 33 and the cutter 34 to move downward, and the cutter 34 enters the cutting groove 301 synchronously. When the cutter 34 contacts the cable, the cable is cut.
