The elastic component includes an extension arm 120 fixed on the cutting frame 115, and the cutting frame 115 is rotatably matched with the rack sliding frame 123 through a swing shaft 122, wherein the swing shaft 122 is fixedly matched with the rack sliding frame 123, and the swing shaft 122 is rotatably matched with the cutting frame 115, and a swing rod 121 is fixed on the swing shaft 122, and the swing rod 121 is elastically connected to the extension arm 120 through an elastic belt 119, and a magnetic block 118 is movably installed on the swing rod 121, and a separation electromagnet 117 that magnetically cooperates with the magnetic block 118 is fixedly installed on the cutting frame 115. The cutting frame 115 is fixed on the annular rotating frame 112, and the annular rotating frame 112 is rotatably mounted on the toothless ring 114, and the toothless ring 114 is fixed on the supporting side plate 109, and the supporting side plate 109 and the positioning frame 101 are both fixed on the base 113.The toothless ring 114 is provided with multiple sections of toothless teeth, so that the loose gear 116 and the toothless ring 114 form intermittent meshing transmission. A driving motor 110 is fixedly installed on the supporting side plate 109, and the output shaft of the driving motor 110 is connected to the annular rotating frame 112 through a transmission belt 111.

[0020] The working principle of a high-voltage cable insulation stripping device disclosed in the present invention is as follows: insert the high-voltage cable that needs to be stripped of the insulation layer into the cable sleeve 106 (cables with different diameters correspond to cable sleeves 106 with different inner diameters, and the outer diameters of the cable sleeve 106 are the same, so that it can better cooperate with the positioning frame 101), and then insert the lower pressing block 105 into the positioning groove 107 and the limiting groove 108 to fix the cable sleeve 106, and then start the locking electromagnet 104, the locking electromagnet 104 generates magnetic force, and the locking electromagnet 104 will attract the lower pressing block 105 to squeeze the cable, thereby fixing the cable on the cable sleeve 106. Before fixing the cable, it is necessary to first determine the length of the insulation layer to be stripped, so pull the scale rod 102 so that the limiting conductive sheet 103 contacts one end of the cable, and determine the length of the insulation layer to be stripped by the scale on the scale rod 102.

[0021] Before the cable is inserted into the cable sleeve 106, the cutter 126 needs to be manually lifted, and the elastic belt 119 is stretched. When the position of the cable is determined, the cutter 126 is lowered, and the cutter 126 is on the surface of the cable insulation layer.

[0022] Start the drive motor 110, and the output shaft of the drive motor 110 drives the annular rotating frame 112 to rotate through the transmission belt 111, and the annular rotating frame 112 will rotate on the toothed ring 114. At this time, the cutting frame 115 on the annular rotating frame 112 will also rotate accordingly, and the rack sliding frame 123 on the cutting frame 115 will also rotate accordingly, and the rack 124 on the rack sliding frame 123 will also rotate accordingly, and the tool frame 125 and the tool 126 on the rack 124 will also rotate accordingly, and at this time the tool 126 will rotate on the surface of the insulation layer of the cable. At the same time, when the cutter 126 rotates, the floating gear 116 on the rack sliding frame 123 will also rotate accordingly. The floating gear 116 is in meshing relationship with the toothed ring 114. Therefore, when the floating gear 116 rotates, it will also rotate. The rotation of the floating gear 116 will drive the input shaft of the planetary gearbox 132 to rotate, and the output shaft of the planetary gearbox 132 will drive the driving gear 131 to rotate. The rotation of the driving gear 131 will drive the rack 124 to move linearly. The linear movement of the rack 124 will drive the tool holder 125 and the cutter 126 to move linearly. At this time, the cutter 126 will cut the insulation layer of the cable. When the floating gear 116 rotates to the toothed section position of the toothed ring 114, under the action of the reset spring 129, the rack 124 will return to its initial position. At this time, the cutter 126 will move in the opposite direction, thereby cutting the insulation layer of the cable again.

[0023] The conductive copper core of the cable is electrically connected to the limiting conductive sheet 103, and then a power supply and a separation electromagnet 117 are connected in series between the limiting conductive sheet 103 (or directly connected to the conductive copper core of the cable) and the cutter 126. When the cutter 126 finishes cutting the insulation layer of the cable, the cutter 126 will contact the conductive copper core inside the cable, thereby forming a closed loop (or an NPN transistor is used to control the start state of the separation electromagnet 117, and the NPN transistor is used as a trigger switch for starting the separation electromagnet 117, that is, the collector and emitter of the NPN transistor are connected in series in the circuit controlling the start of the separation electromagnet 117, and the base and emitter of the NPN transistor are connected in series in the circuit of the cutter 126, the power supply and the limiting conductive sheet 103 or the cable copper core). ), at this time, the separation electromagnet 117 is started, and the separation electromagnet 117 will attract the magnetic block 118 after being started. The magnetic block 118 is installed on the swing rod 121, so the swing rod 121 will swing towards the separation electromagnet 117, so that the elastic belt 119 is in a stretched state. At the same time, the swing of the swing rod 121 will drive the rack slide frame 123 to swing through the swing shaft 122, thereby lifting the tool frame 125 and the tool 126, that is, the tool 126 is separated from the cable. A limit trigger button is set on the swing rod 121 and the cutting frame 115. The button is used to control the stop of the drive motor 110. When the magnetic block 118 is attracted by the separation electromagnet 117, the swing rod 121 will swing to the position of the button, thereby stopping the drive motor 110. This can effectively prevent the tool 126 from excessively cutting the cable insulation layer, thereby causing damage to the copper core.
