[0033] The utility model is further described below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 6 As shown, a core wire lengthening and shortening mechanism described in the utility model includes a wire pulling linear module and a wire pulling clamping assembly D2 connected to the wire pulling linear module;

[0035] The wire pulling clamping assembly D2 includes a clamping lower fixed seat D203 and a clamping front fixed seat D201 fixed on the clamping lower fixed seat D203; a plurality of wire clamping modules are arranged on the clamping lower fixed seat D203; the wire clamping module includes a wire pulling clamping plate D202, a wire pulling cylinder D204 fixed at one end on the clamping lower fixed seat D203 and a wire pulling slide seat D206 slidably connected to the clamping front fixed seat D201; the number of the wire pulling clamping plates D202 is two; the wire pulling clamping plates D202 are in an "L" shape;

[0036] The clamping front fixing seat D201 is rotatably connected to two wire pulling shafts D205; the two wire pulling clamping plates D202 are rotatably connected to the two wire pulling shafts D205 respectively;

[0037] The upper and lower sides of the wire pulling slide D206 are both provided with wire pulling sliding grooves D206a; one end of the wire pulling clamp D202 extends into the wire pulling sliding groove D206a; the other end of the wire pulling cylinder D204 is fixed on the wire pulling slide D206;

[0038] The wire pulling cylinder D204 is used to drive the wire pulling slide D206 to move, and the front and rear inner walls of the wire pulling slide groove D206a respectively push or pull the wire pulling clamp D202, and the wire pulling clamp D202 rotates around the wire pulling shaft D205, so that the two wire pulling clamps D202 are flipped, and the two wire pulling clamps D202 clamp or release the wire core;

[0039] After the wires are arranged, they are aligned with the corresponding clamping modules respectively. The wire-pulling linear module moves the two open wire-pulling clamps D202 until the wire core is inserted between the two open wire-pulling clamps D202. Then the wire-pulling cylinder D204 is actuated, so that the two wire-pulling clamps D202 clamp the wire core. The wire-pulling linear module drives the wire-pulling clamping assembly D2 to translate to the manipulator that feeds the wire core into the twisted copper wire. After the manipulator clamps the wire core, the wire-pulling clamping assembly D2 releases the clamping of the wire core. Through this structure, multiple wire cores are synchronously pulled into place, which reduces labor intensity, improves wire-pulling efficiency, and the length of the wire pull can be precisely controlled, improving the quality of the twisted copper wire.

[0040] As a preferred embodiment of the utility model, it also includes a wire positioning component; the wire positioning component includes a wire pulling and clamping component D1 and a wire clamping plate D9; a plurality of wire clamping line groups are arranged on the wire clamping plate D9; the wire clamping line group is composed of two wire clamping lines D901 and a wire limiting top block D902 arranged between the two wire clamping lines D901; the gap between the wire clamping lines D901 is a wire clamping gap; the width of the wire clamping gap gradually decreases as it approaches the wire limiting top block D902; the inner side wall of the wire clamping line D901 close to one end of the wire limiting top block D902 is provided with a wire clamping line concave D901a;

[0041] The wire-pulling and clamping assembly D1 includes a wire-pulling and clamping cylinder D101 and a wire-pulling and clamping block D102; the wire-pulling and clamping block D102 is connected to the piston rod end of the wire-pulling and clamping cylinder D101; and a plurality of wire-pulling and clamping cone blocks D102a are arranged on the wire-pulling and clamping block D102;

[0042] The wire positioning assembly is fixed to the external bracket;

[0043] The two clamping wires D901 are made of elastic material and have a certain elasticity. After the wire is inserted into the top of the two clamping wires D901, the wire core is clamped and fixed on the two clamping wires D901 through the concave shapes D901a of the clamping wires on both sides, waiting for the wire clamping assembly D2 to grab it; the wire clamping cylinder D101 drives the wire clamping cone block D102a on the wire clamping block D102 to move, and the wire clamping cone block D102a is inserted between the two clamping wires D901 on the same clamping wire group, and then as the wire is pulled, the wire is clamped. The wire opening and clamping cone block D102a gradually penetrates into the two clamping lines D901, and the inclined surface of the wire opening and clamping cone block D102a is pressed against the inner wall of the two clamping lines D901, gradually opening the two clamping lines D901. The two clamping lines D901 release their clamping of the wire core, and the wire pulling and clamping assembly D2 can pull the wire core to a specified extent. Then the wire opening and clamping cone block D102a is released, and the two clamping lines D901 clamp the wire again, so that the wire is straightened in the section from the wire clamp plate D9 to the wire pulling and clamping assembly D2.

[0044] As a preferred embodiment of the present invention, the number of the wire clamping modules is at least two; the number of the wire clamping modules is paired according to the number of wire cores of the cable.

[0046] The two ends of the wire drawing motor D8 are respectively fixed on the wire drawing screw rod D6 and the wire drawing fixed seat D5; the wire drawing sliding seat D3 is fixed on the clamping lower fixed seat D203;

[0047] After the wire pulling motor D8 is started, it drives the wire pulling screw D6 to rotate. The wire pulling screw D6 rotates in the wire pulling screw nut. The wire pulling screw D6 pushes the wire pulling screw nut, the wire pulling sliding seat D3 and the clamping lower fixed seat D203 to slide along the length direction of the wire pulling guide rail D4, thereby realizing precise control of the wire pulling distance of the wire pulling clamping assembly D2.
