DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Specifically, a fast wire twisting device for electric wires includes a workbench 1, a connecting plate 2 is installed at one end of the workbench 1, a first servo motor 3 is installed on the connecting plate 2, an output shaft of the first servo motor 3 passes through the connecting plate 2 and is connected to a rotating disk 4, a plurality of wire outlet rollers 5 are installed on the rotating disk 4, two support plates 6 are installed on the workbench 1, the same first twisting wheel 7 is rotatably installed on the two support plates 6, a second twisting wheel 8 is arranged below the first twisting wheel 7, and both ends of the second twisting wheel 8 are slidably installed on the corresponding support plates 6, A wire take-up frame 9 is installed on the workbench 1, and a first connecting block 10 and a second connecting block 11 are relatively installed on the top of the wire take-up frame 9, a second servo motor 12 is installed on the first connecting block 10, and a threaded rod 13 is installed on the output shaft of the second servo motor 12, and the end of the threaded rod 13 away from the second servo motor 12 is rotatably connected to the workbench 1, and a threaded block 14 is threadedly connected to the threaded rod 13, and the threaded block 14 is slidably connected to the wire take-up frame 9, and a third motor 15 is installed on the threaded block 14, and an electric telescopic rod 16 is movably connected to the output end of the third motor 15, and a wire take-up drum 17 is slidably connected to the output shaft of the electric telescopic rod 16.

[0022] When it is necessary to twist the wires, the staff first pulls out the wires on the wire delivery drum 5 and places them between the first twisting wheel 7 and the second twisting wheel 8, and then turns on the first servo motor 3. The operation of the first servo motor 3 drives the rotating disk 4 connected thereto to rotate, so that the wires on the wire delivery drum 5 rotate and entwine with each other, thereby achieving the effect of twisting the wires. After that, the wires after twisting are wound around the take-up drum 17, and the third motor 15 is turned on. The rotation of the third motor 15 drives the take-up drum 17 to rotate, thereby achieving the purpose of winding the wires after subsequent twisting onto the take-up drum 17. When it is necessary to remove the take-up drum 17 from the device, the third motor 15 is turned on. The second servo motor 12 drives the threaded rod 13 installed thereon to rotate synchronously. When the threaded rod 13 rotates, the threaded block 14 threadedly connected thereon is driven to move vertically downward along the direction of the threaded rod 13, thereby driving the third motor 15 installed on the threaded block 14 to move downward synchronously, so that the electric telescopic rod 16 movably connected to the third motor 15 moves downward, thereby driving the wire-taking drum 17 slidably installed on the electric telescopic rod 16 to move downward, and then the electric telescopic rod 16 is retracted, so that the wire-taking drum 17 falls off the electric telescopic rod 16, thereby achieving the purpose of removing the wire-taking drum 17 from the device.

[0023] Specifically, in the present embodiment, a rotating hole 18 is opened on the connecting plate 2, and the centers of the rotating hole 18, the first servo motor 3 and the rotating disk 4 are on the same axis, so that the output shaft of the first servo motor 3 can pass through the connecting plate 2 through the rotating hole 18 and be connected to the rotating disk 4. Thus, while the connecting plate 2 provides support for the first servo motor 3, the first servo motor 3 will not be blocked by the connecting plate 2, thereby avoiding the situation that the first servo motor 3 cannot be connected to the rotating disk 4, so that when the first servo motor 3 is running, it can drive the rotating disk 4 to run synchronously through the rotating hole 18.

[0024] Specifically, in the present embodiment, a first slide groove 19 is provided on both support plates 6, both ends of the second stranding wheel 8 are matched with the first slide groove 19, and both ends of the second stranding wheel 8 are threadedly connected with nuts 20, so that the second stranding wheel 8 can be slidably connected to the two support plates 6 through the first slide groove 19. When the specifications of the wires are different, the specifications of the stranded wires can be adjusted by manually sliding the second stranding wheel 8 in the first slide groove 19. When adjusted to a suitable position, the position of the second stranding wheel 8 can be positioned by tightening the nut 20 to prevent it from shifting under pressure.

[0025] Specifically, in the present embodiment, a connecting shaft 21 is installed at the center of the rotating disk 4, and a wire drum 22 is installed at one end of the connecting shaft 21 away from the rotating disk 4. A plurality of holes are opened on the wire drum 22, and the number and position of the holes correspond to the number and position of the wire outlet rollers 5, so that the wires on the wire outlet rollers 5 can be led out through the corresponding holes on the wire drum 22, and thus be placed on the first twisting wheel 7 and the second twisting wheel 8, thereby avoiding the situation that the wires on the wire outlet rollers 5 are pulled out but not twisted in time, causing the wires to be tangled around the rotating disk 4.

[0026] Specifically, in the present embodiment, a support shaft 23 is installed on the second connecting block 11, and one end of the support shaft 23 away from the second connecting block 11 is installed on the workbench 1, a moving block 24 is slidably connected to the support shaft 23, and one end of the moving block 24 close to the threaded rod 13 is installed with a bearing 25, and one end of the electric telescopic rod 16 away from the third motor 15 is sleeved in the bearing 25, so that when the third motor 15 drives the electric telescopic rod 16 to rotate, since the end of the electric telescopic rod 16 away from the third motor 15 is connected to the bearing 25, the electric telescopic rod 16 can be rotated, thereby driving the wire-winding drum 17 slidably connected thereto to rotate, thereby rolling the twisted wires onto the wire-winding drum 17.

[0027] Specifically, in this embodiment, a second slide groove 26 is provided on the wire take-up frame 9, and the second slide groove 26 is adapted to the electric telescopic rod 16, so that the electric telescopic rod 16 can be slidably connected to the wire take-up frame 9 through the second slide groove 26, and when the threaded block 14 moves, the electric telescopic rod 16 can be driven to move on the wire take-up frame 9.

[0028] Specifically, in this embodiment, a threaded hole 27 is provided on the threaded block 14, and the threaded hole 27 is adapted to the threaded rod 13, so that the threaded block 14 can be threadedly connected to the threaded rod 13 through the threaded hole 27, so that when the threaded rod 13 rotates, the threaded block 14 threaded thereon can move synchronously along the direction of the threaded rod 13.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
