TECHNICAL FIELD

[0001] The utility model relates to the electric wire stranding technical field, more exactly relates to a kind of electric wire stranding machine. BACKGROUND

[0002] Stranding machine is a kind of stranding mechanical equipment that can be widely applied to various soft / hard conductors, for example: various soft / hard conductors (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) and electronic wires (such as: power cord, earphone cord, telephone cord, PVC cord, network cable, etc.), so that multiple single conductors are twisted into a strand, meeting the process requirements of wire rod.

[0003] The existing stranding machine is mostly used to twist multiple single long conductors into a long conductor wire, with a length of several kilometers. Such equipment performs well when processing long wires, ensuring uniform stranding and high-quality output of the wires. However, it is not suitable for some double-stranded short wires (such as sensor lead wires, internal wires of electrical connectors and balanced signal wires in audio equipment), which are several centimeters to one meter long. Manual stranding is usually used, which is low in efficiency. SUMMARY

[0004] The utility model aims at providing an electric wire stranding machine, which reduces labor intensity and is suitable for double-stranded short wires of different lengths and types.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] An electric wire stranding machine includes a workbench, a vertical plate fixedly connected to the workbench, a first mounting plate fixedly installed at one end of the vertical plate, a second mounting plate provided at the other end of the vertical plate, and a horizontal displacement mechanism for driving the second mounting plate to move horizontally. The first mounting plate and the second mounting plate are oppositely arranged, and each side of the first mounting plate and the second mounting plate opposite to each other is provided with a U-shaped frame. A rotary motor is installed on the first mounting plate and the second mounting plate for driving the U-shaped frame to rotate. A clamping mechanism is provided on the U-shaped frame.

[0007] Further, a first sliding groove and a second sliding groove are parallelly provided on the vertical plate. The horizontal displacement mechanism includes a lead screw provided in the first sliding groove and a lead screw motor for driving the lead screw to rotate. A guide rod is fixedly provided in the second sliding groove, and the second mounting plate is slidably sleeved on the guide rod. The second mounting plate is threadedly connected with the lead screw.

[0008] Further, the clamping mechanism comprises a slide rod fixedly connected between two ends of the U-shaped frame, a bidirectional screw rod is rotationally arranged between the two ends of the U-shaped frame, a drive motor for driving rotation of the bidirectional screw rod is installed on the U-shaped frame, and clamping plates are threadedly connected to two ends of the bidirectional screw rod and slide on the slide rod.

[0009] Further, a groove is formed in the inner side of one clamping plate, and a protruding portion corresponding to the groove is arranged on the inner side of the other clamping plate.

[0010] Further, a receiving groove is formed in the upper surface of the workbench.

[0011] Compared with the prior art, the workbench has the following beneficial effects:

[0012] The wire twisting process is driven by the rotary motor, and the operator only needs to put the two ends of the wire into the clamping mechanism and start the equipment to complete the twisting, thereby simplifying the operation process and reducing the labor intensity; the distance between the two clamping mechanisms is adjusted by the horizontal displacement mechanism, which is suitable for double-strand short wire rods of different lengths and types and meets the needs of different application scenarios.

DETAILED DESCRIPTION

[0016] As Figure 1 and Figure 2 shown, a wire twisting machine comprises a workbench 1, a vertical plate 2 is fixedly connected to the workbench 1, a first mounting plate 3 is fixedly installed at one end of the vertical plate, a second mounting plate 4 and a horizontal displacement mechanism for driving the second mounting plate 4 to move horizontally are arranged at the other end of the vertical plate 2, the first mounting plate 3 and the second mounting plate 4 are oppositely arranged, U-shaped frames 5 are arranged on the opposite sides of the first mounting plate 3 and the second mounting plate 4, rotary motors 6 for driving rotation of the U-shaped frames 5 are installed on the first mounting plate 3 and the second mounting plate 4, and clamping mechanisms are arranged on the U-shaped frames 5.

[0017] The vertical plate 2 is provided with a first sliding groove 201 and a second sliding groove 202 in parallel. The horizontal displacement mechanism includes a lead screw 7 disposed in the first sliding groove 201 and a lead screw motor 8 for driving the lead screw 7 to rotate. A guide rod 9 is fixedly disposed in the second sliding groove 202. The second mounting plate 4 is slidably sleeved on the guide rod 9. The second mounting plate 4 is threadedly connected to the lead screw 7.

[0018] The clamping mechanism includes a slide rod 10 fixedly connected between the two ends of the U-shaped frame 5. A bidirectional screw 11 is rotatably arranged between the two ends of the U-shaped frame 5. A drive motor 12 for driving the bidirectional screw 11 to rotate is installed on the U-shaped frame 5. Both ends of the bidirectional screw 11 are threadedly connected to a clamping plate 13, and the clamping plate 13 is slidably sleeved on the slide rod 10.

[0019] One of the clamping plates 13 has a groove 131 on its inner side, and the other clamping plate 13 has a protrusion 132 on its inner side corresponding to the groove 131.

[0020] The upper surface of the workbench 1 is provided with a storage groove 101.

[0021] Working principle:

[0022] The operator places one end of the short double-strand wire to be twisted into the U-shaped frame 5 on the first mounting plate 3, and controls the bidirectional screw 11 to rotate by the drive motor 12, causing the two clamping plates 13 to move relative to each other, thereby firmly clamping the wire. The operator then drives the lead screw 7 to rotate by the lead screw motor 8, adjusts the position of the second mounting plate 4, places the other end of the short double-strand wire into the U-shaped frame 5 on the second mounting plate 4, and uses the clamping mechanism to fix the wire. The operator then starts the rotary motor 6, causing the U-shaped frames 5 on the first mounting plate 3 and the second mounting plate 4 to rotate synchronously, driving the wire clamped between them to twist. After twisting is completed, the rotary motor 6 is turned off, the drive motor 12 drives the bidirectional screw 11 to rotate, the two clamping plates 13 separate, and the twisted wire falls into the storage slot 101.

[0023] This invention achieves a fast and efficient stranding process through an automated clamping and rotation mechanism, which can adapt to short wires of various types and lengths to meet the needs of different application scenarios.
