Description

Technical Field

[0001] The present invention relates to the technical field of automobile high-voltage cable production, in particular to an automobile high-voltage cable production device. Background Art

[0002] Cables are usually composed of several or several groups of wires, usually a rope-like cable formed by twisting several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation. During the processing and use of the cable, the cable needs to be cut, so the corresponding cutting device is required.

[0003] For example, the Chinese patent with publication number "CN209902121U" discloses "a cable cutting device", whose main structure includes a mounting seat, a pressure plate fixedly installed on the front of the mounting seat, and a fixed block fixedly installed on one side of the top of the pressure plate, a fixed rod fixedly installed on the top of the fixed block, and a connecting rod slidably installed on one end of the fixed rod, a connecting block fixedly installed on the other side of the fixed block, and a connecting groove is provided on the connecting block, and the connecting block is movably connected to the connecting rod through the connecting groove, a mounting block fixedly installed at the central position of the front of the mounting seat, and a lower cutter fixedly installed on the top of the mounting block. In this cable cutting device, the lower cutter and the upper cutter cooperate to cut the cable through an electric hydraulic rod. Therefore, the power required comes from the electric hydraulic rod, which uses the electric hydraulic rod to drive the lower cutter and the upper cutter to approach each other, thereby performing an extrusion-type cutting on the cable located between the lower cutter and the upper cutter.

[0004] However, the maximum cutting force between the lower cutter and the upper cutter is fixed, and the maximum cutting force is related to the maximum power of the motor in the electric hydraulic rod. Once the compressive strength of the cable is greater than the above-mentioned maximum cutting force, since the above-mentioned cable cutting device does not protect the electric hydraulic rod, it is very likely to cause damage to the motor in the electric hydraulic rod. Summary of the Invention

[0020] See also Figure 1 and Figure 2 A production device for automotive high-voltage cables includes a component mounting sleeve 1 with a component mounting cavity 2 provided therein and a drive motor 4 fixedly mounted on the top of the component mounting sleeve 1 through a motor fixing housing 3. The power of the drive motor 4 is used as the power required for cutting, and the cutting or component resetting function can be achieved by controlling the rotation direction of the rotor 5 in the drive motor 4.

[0021] To achieve the thread cutting function, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , it is necessary to set up a threaded rotating cutting mechanism 6, which is internally provided with a rotatable threaded sleeve 64, an externally threaded rod 66 connected to the threaded sleeve 64 through a threaded structure and capable of longitudinal movement, a longitudinal telescopic rod 68 that can move with the externally threaded rod 66 and prevent the externally threaded rod 66 from rotating, and a movable cutting blade 611 that moves longitudinally with the longitudinal telescopic rod 68 and can perform extrusion cutting on the cable. When the threaded sleeve 64 rotates, due to the threaded structure connection and the longitudinal telescopic rod 68 being able to prevent the externally threaded rod 66 from rotating, the externally threaded rod 66 will undergo longitudinal displacement, thereby driving the longitudinal telescopic rod 68 to drive the movable cutting blade 611 to move downward. At this time, the cable between the movable cutting blade 611 and the bottom cutting base 69 will be squeezed and cut until the cutting is completed, thereby realizing the threaded cutting function.

[0022] For the specific structure of the threaded rotary cutting mechanism 6, please refer to Figure 3 and Figure 4, including a longitudinal hollow shell 61, the interior of the longitudinal hollow shell 61 is provided with a No. 1 component movable cavity 62, the top of the longitudinal hollow shell 61 is provided with a No. 2 component installation cavity 63, the cylinder at the bottom of the threaded sleeve 64 is installed in the interior of the No. 2 component installation cavity 63 through a bearing, the bottom end of the longitudinal hollow shell 61 is provided with a No. 1 rod body through-hole 67 connecting the space below it and the bottom end of the No. 1 component movable cavity 62, and a bottom cutting base 69 is fixedly installed directly below the longitudinal hollow shell 61 through a longitudinal limiting slide rod 610, and a limiting slide hole 612 capable of axial movement along the longitudinal limiting slide rod 610 is provided on one side of the movable cutting blade 611, and an internal threaded hole 65 installed on the rod body of the external threaded rod 66 through a threaded structure is provided in the center of the threaded sleeve 64, and a through-hole is fixedly installed at the bottom end of the external threaded rod 66. The longitudinal telescopic rod 68 is through-hole 67 of the rod body, and the bottom end of the longitudinal telescopic rod 68 is fixedly connected to the top of the movable cutting blade 611. The threaded structure includes an internal threaded structure arranged inside the internal threaded hole 65 and an external threaded structure arranged at the rod body of the external threaded rod 66, and the internal threaded structure matches the external threaded structure. The structural shape of the cross section of the No. 1 rod body through-hole 67 is consistent with the structural shape of the cross section of the longitudinal telescopic rod 68, both of which are polygonal structures, and the structural dimensions of the cross section of the No. 1 rod body through-hole 67 match the structural dimensions of the cross section of the longitudinal telescopic rod 68.

The disk 711 rotates, and the lower rotating disk 711 will drive the inserted protrusion column 713 to rotate. During the cutting process, once the cutting resistance is greater than the elastic pressure of the coil spring 78, the torsion between the lower rotating disk 711 and the upper rotating disk 710 will cause the coil spring 78 to be compressed, and the ball 715 will disengage from the interior of the hemispherical groove 714 located above, so that the rotor 5 can continue to drive the upper rotating disk 710 to rotate, and the lower rotating disk 711 will not form a greater torsional resistance to the upper rotating disk 710, and thus will not further increase the resistance to the drive motor 4 without affecting the basic rotation of the drive motor 4, thereby forming an effective protection measure for the drive motor 4.

[0024] For the specific structure of the clutch linkage mechanism 7, please refer to Figure 5 and Figure 6, including a coil spring 78, a rotor fixing groove 72 for fixing the rotor 5 is provided at the top of the rotating shell 71, and a No. 2 component movable chamber 73 located above and a No. 3 component movable chamber 75 located below are provided inside the rotating shell 71, and the No. 2 component movable chamber 73 and the No. 3 component movable chamber 75 are connected through the No. 2 rod body through-hole 74, and the bottom end of the No. 3 component movable chamber 75 is connected to the outside space through the shaft body mounting hole 76, and a built-in movable plate 77 capable of moving along its axial direction is placed inside the No. 2 component movable chamber 73, and a coil spring 78 is installed above the built-in movable plate 77 to generate downward elastic pressure thereon, and a longitudinal movable rod 79 is fixedly installed at the bottom end of the built-in movable plate 77 passing through the No. 2 rod body through-hole 74, and an upper rotating disk 710 is fixedly installed at the bottom end of the longitudinal movable rod 79 located inside the No. 3 component movable chamber 75. A rotatable longitudinal rotating shaft 712 is installed inside the body mounting hole 76 through a bearing, and a lower rotating disk 711 is fixedly installed on the top of the longitudinal rotating shaft 712. The lower rotating disk 711 and the upper rotating disk 710 are respectively provided with a plurality of hemispherical grooves 714 arranged in a circular array on the opposite end faces, and a ball 715 is installed between the two corresponding hemispherical grooves 714. The bottom end of the longitudinal rotating shaft 712 is provided with an inserted protruding column 713 with an integral structure therewith. The structural shape of the cross section of the movable cavity 73 of the second component is consistent with the structural shape of the cross section of the built-in movable plate 77, both of which are polygonal structures, and the structural dimensions of the cross section of the movable cavity 73 of the second component match the structural dimensions of the cross section of the built-in movable plate 77, the structural radius of the hemispherical groove 714 matches the structural radius of the ball 715, and the depth of the hemispherical groove 714 is smaller than the structural radius of the ball 715.

[0025] To provide different gear ratios as required, please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , it is necessary to set up a belt-type linkage mechanism 8, which is internally provided with a No. 1 pulley 84 that rotates with the insertion of the protruding column 713, a No. 2 pulley 86 that can drive the threaded sleeve 64 to rotate, and a belt 88 that links the No. 1 pulley 84 and the No. 2 pulley 86. The insertion of the protruding column 713 will drive the No. 1 pulley 84 to rotate, and the No. 1 pulley 84 drives the No. 2 pulley 86 to rotate through the belt 88, and the No. 2 pulley 86 can drive the threaded sleeve 64 to rotate, thereby achieving a linkage effect. At the same time, the user can adopt different radius ratios of the No. 1 pulley 84 and the No. 2 pulley 86, so as to provide different rotation ratios as needed.

[0026] For the specific structure of the belt-type linkage mechanism 8, please refer to Figure 7 and Figure 8, including a connecting plate 81, the upper surface of which is fixedly mounted with a fixing ring 83 through a longitudinal connecting rod 82, and the fixing ring 83 is fixedly mounted on the outer periphery of the rotating shell 71, and a No. 1 pulley 84 and a No. 2 pulley 86 that can rotate are mounted in the plate body of the connecting plate 81 through bearings, and the No. 1 pulley 84 and the No. 2 pulley 86 are linked by a belt 88, and the upper end of the No. 1 pulley 84 is provided with an inner concave structure and a limiting insertion groove 85 for fixing and installing the inserted protruding column 713, and the center of the No. 2 pulley 86 is provided with a component fixing cavity 87 fixedly mounted on the outside of the cylinder of the threaded sleeve 64.

[0027] When in use, the drive motor 4 is started, the rotor 5 will drive the rotating shell 71 to rotate, and the rotating shell will force the ball 715 to drive the lower rotating disk 711 to rotate through the built-in movable plate 77, the longitudinal movable rod 79 and the upper rotating disk 710, and the lower rotating disk 711 will drive the inserted protruding column 713 to rotate, and the inserted protruding column 713 will drive the No. 1 pulley 84 to rotate, and the No. 1 pulley 84 drives the No. 2 pulley 86 to rotate through the belt 88, and the No. 2 pulley 86 can drive the threaded sleeve 64 to rotate. When the threaded sleeve 64 rotates, the threaded structure connection and the longitudinal telescopic rod 68 can prevent the external threaded rod 66 from rotating, and the external threaded rod 66 will undergo longitudinal displacement, thereby driving the longitudinal telescopic rod 68 to drive the mobile cutting The blade 611 moves downward, and at this time the cable between the movable cutting blade 611 and the bottom cutting base 69 will be squeezed and cut until the cutting is completed, thereby realizing the threaded cutting function. Once the cutting resistance is greater than the elastic pressure of the coil spring 78, the torsion between the lower rotating disk 711 and the upper rotating disk 710 will cause the coil spring 78 to be compressed, and the ball 715 will be separated from the interior of the hemispherical groove 714 located above, so that the rotor 5 can continue to drive the upper rotating disk 710 to rotate, and the lower rotating disk 711 will not form a greater torsional resistance to the upper rotating disk 710, and thus will not further increase the resistance to the drive motor 4 without affecting the basic rotation of the drive motor 4, thereby forming an effective protection measure for the drive motor 4.
