Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering wiring, in particular to an electrical engineering wiring device. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. In order for the cables to meet the requirements of use, they need to be cut, stripped, heat-shrink tubing baked, steel strands cut, bent, and punctured with wire clamps. However, most of the above operations are done manually, which is very laborious and inefficient.

[0003] Through searching, Chinese patent publication number CN113851909B discloses an electrical engineering wiring device, including a base, a vertical plate provided on the top of the base, a horizontal plate provided on one side of the vertical plate, a groove provided on the bottom surface of the horizontal plate, a first screw and a second screw provided in the groove, a first gear and a first movable block provided on the outer surface of the first screw, a clamping mechanism provided on the bottom surface of the first movable block, a second gear and a second movable block provided on the outer surface of the second screw, and a movable stripping mechanism fixedly connected to the bottom surface of the second movable block. In this solution, during the stripping process, the movable stripping mechanism is always located between the fixed stripping mechanism and the clamping mechanism on the first movable block, so that when the stripping length of the wire is long, an additional cut can be added in the middle to divide the stripping length into two, and the two sections of insulation layer can be stripped at the same time, reducing the pressure when stripping the insulation layer, protecting the wire core, and avoiding multiple operations that reduce work efficiency. For convenience, existing wiring devices directly twist two wires together during wiring. However, this connection method is prone to falling apart after the two wires are pulled, and when cutting the insulation layer, not only is the length difficult to control, but the wire core is also easily damaged. Therefore, an electrical engineering wiring device is proposed to solve the above problems. Summary of the Invention

The end face of the winding sleeve 104 is in a "C" shape, and the outside of the winding sleeve 104 is provided with teeth and engages with the teeth of the pushing tooth 103. The wire stripping ring 10 can be pushed by two groups of pushing teeth 103 to make the winding sleeve 104 rotate around the wire, and can be directly taken out from the gap after the wire is connected.

[0029] The wire clamping assembly 2 also includes a winding shell 12, and an array of induction knife groups 11 is arranged on the surface of the winding sleeve 104. The induction knife group 11 includes a supporting shell 111, and a stripping blade 112 is slidingly arranged on the inner side of the supporting shell 111. A pushing mechanism 113 is arranged on the inner side of the supporting shell 111 for driving the extension and retraction of the stripping blade 112. A resistance sensor 114 is arranged on the top of the stripping blade 112 for controlling the start and stop of the pushing mechanism 113. The induction knife group 11 can pierce the insulation layer of the wire by extending the stripping blade 112, and the resistance sensor 114 is used to control the pushing mechanism 113 to stop in time to prevent the wire core from being damaged.

[0030] A winding assembly 13 is arranged inside the winding shell 12, and the winding shell 12 includes a winding motor 121. A sprocket is provided at the output end of the winding motor 121.

The winding telescopic rod 132 is arranged on the inner side of the twisting sleeve 123 to drive the winding frame 131 to clamp the cable. The winding assembly 13 can not only clamp the insulation layer to prepare for removing the insulation layer, but also clamp the wire core so that the opposite wire core ends can be wound around the wire at the central axis position, so that the wires at both ends are connected.

[0032] When in use, first place the two wires that need to be connected on the surface of the wire clamping wheels 8 at both ends, and start the wire routing motor 81 to drive the wire routing wheel 82 to rotate, so that the rubber sleeve 83 drives the wire into the gap between the wire clamping wheel 8 and the wire lifting platform 6, and starts the wire control motor 61 according to the diameter of the wire, so that the wire is placed in the chute of the wire platform 63, and starts the driving source 74 to drive the connection shaft 73 to rotate, so that the connection shaft 73 rotates and drives the flip columns 72 on both sides to rotate, so that the two groups of flip columns 72 drive the wire clamping wheel 8 to rotate, so that the outer circumference of the rubber sleeve 83 fits on the wire. The surface of the wire insulation layer is controlled by extending the telescopic rod 75 to squeeze and fit the rubber sleeve 83 with the wire insulation layer. By starting the wire running motor 81 to drive the wire running wheel 82 to rotate, the wire clamping wheel 8 rotates to push the wire into the inner side of the wire stripping shell 9. When the wire is extended to a suitable length, the stripping blade 112 is driven to be inserted into the insulation layer of the wire by starting the pushing mechanism 113. The resistance sensor 114 is set to control the pushing mechanism 113 to stop in time to prevent the wire core from being damaged. By starting the winding motor 102 to drive the pushing tooth 103, the winding sleeve 10 4 is pushed, so that the induction knife group 11 rotates around the wire following the winding sleeve 104, so that the insulation layer on the outside of the wire is cut off, and the winding frame 131 is driven by starting the winding telescopic rod 132, so that the winding frame 131 is clamped on the outside of the cut insulation layer, and the stripping blade 112 is retracted and reset. The wire is pulled out in the opposite direction by the stripping blade 112 and the wiring motor 81 is driven to remove the wire, so that the insulation layer clamped by the winding frame 131 is stripped off and pulled away, and the winding frame 131 releases the insulation layer, and the clamping wheel 8 pushes the wire again, and then the adjusting screw 5 is rotated to control The spacing between the center axes of the left and right groups of movable seats 4 is achieved by starting the positioning clamp 3 to clamp the middle section of the connection position of the two wires, and by starting the winding assembly 13 to clamp the outside of the two wires, and by starting the twisting motor 121 to drive the winding shaft 122, the twisting sleeve 123 is pushed to rotate, so that the two groups of winding assemblies 13 rotate about their own central axes, so that the wire ends at both ends are wound around the outside of the opposite wires, so that the two wires are connected. After the cable is connected, the stripping shell 9 and the winding shell 12 are rotated to remove the connected wires from the top.
