[0029] The wire stranding end includes a first fixed bracket 2 and a second fixed bracket 7. A corresponding first bearing 4 is installed on the first fixed bracket 2, and a corresponding second bearing 8 is installed on the second fixed bracket 7. One end of the main shaft 6 is connected to the first bearing 4, and the other end of the main shaft 6 is connected to the second bearing 8; an auxiliary wire stranding device 9 is embedded at the connection between the main shaft 6 and the second bearing 8; the main shaft 6 is a smooth hollow round rod. Among them, a sleeve 3 with a circular hole in the center is sleeved on the protruding part of the main shaft 6 extending out of the first bearing 4.

[0030] A miniaturized wire stranding end adjustable-speed motor 1 is provided on the first fixed bracket 2. The rotating shaft of the miniaturized wire stranding end adjustable-speed motor 1 passes through the first fixed bracket 2, and a motor drive gear 15 is provided at the other end of the first fixed bracket 2; a main shaft gear 14 that cooperates with the motor drive gear is provided at the corresponding position of the main shaft. The motor drive gear 15 and the main shaft gear 14 cooperate with each other to achieve transmission; the structural schematic diagram is shown in Figure 2 .

[0031] Two wire stranding wheels 5 are also provided on the main shaft 6. A plurality of spool supports are fixed on each wire stranding wheel, and a corresponding wire feeding spool 13 is equipped on each spool support; the wire feeding spool 13 can also be provided on the first fixed bracket 2 and feed wire through the circular hole of the sleeve 3 into the smooth hollow round rod that serves as the main shaft 6.

[0032] The wire receiving end includes a wire receiving end base 12. Above the wire receiving end base 12, a wire receiving end motor fixing bracket 10 is provided. One end of the wire receiving end motor fixing bracket 10 is provided with a miniaturized wire receiving end adjustable-speed motor 18. The rotating shaft of the miniaturized wire receiving end adjustable-speed motor 18 is connected to the wire receiving wheel 11 through the wire receiving end motor fixing bracket 10. The rotation of the miniaturized wire receiving end adjustable-speed motor 18 drives the wire receiving wheel 11 to rotate.

[0033] The wire stranding wheels 5 are distributed with inner ring hollow holes and outer ring hollow holes.

[0034] The auxiliary wire stranding device 9 includes a disc with N holes, which is arranged according to the arrangement of the stranded welding wires. The holes of the disc are set to achieve wire stranding with different angular differences in multiple ways. There is also an auxiliary wire strander 16 provided on the side of the second fixed bracket close to the wire receiving end; the auxiliary wire strander includes two wire stranding rods; the two wire stranding rods are spaced apart by a plastic sleeve 17. The structural schematic diagram is shown in Figure 3; Each wire twisting rod is provided with a merging hole; the disc with N holes is used to allow multiple welding wires to pass through, and according to the welding beam structure formed by the welding wires, pass through the corresponding merging holes to realize the wire twisting process of multiple welding wires, and are output by the wire twisting rod arranged at the rear end.

[0035] The installation method of the miniaturized heterogeneous metal multi-wire twisting device is as follows: first, fix the first fixed bracket above the working environment, fix the small twisting end adjustable speed motor shaft end through the hole reserved in the first fixed bracket, and set a motor transmission gear on the small twisting end adjustable speed motor shaft, and fix it by positioning screws, then fix the first bearing and one end of the main shaft on the first fixed bracket in an inlaid manner, then insert the main shaft gear into the main shaft at the corresponding position of the motor transmission gear, and insert the two wheels into the main shaft in sequence, and continue to fix them by positioning screws, and then combine the auxiliary twisting device with the second fixed bracket and the second bearing by embedding, connect it to the other end of the main shaft and fix it, and finally install the wire feeding spool to the corresponding position and fix it, including but not limited to the first fixed bracket, the first twisting wheel, and the second twisting wheel corresponding to the spool support; at this point, the wire feeding end is installed. Fix the wire receiving end base to one end near the auxiliary wire twisting device, and fix the wire receiving end motor fixing bracket, small wire receiving end adjustable speed motor and wire receiving wheel in sequence, and the whole device is assembled. After the overall assembled miniaturized heterogeneous metal multi-wire twisting device is placed in the working environment, add welding wire, and then start working.

[0036] Working status of the miniaturized heterogeneous metal multi-wire twisting device: Since the miniaturized heterogeneous metal multi-wire twisting device is equipped with multiple wire feeding spools (fixed in the pre-reserved holes of the spool support of the wire twisting wheel by screws), the type and quantity of the required twisted wires can be adjusted according to needs to achieve diversity of the finished products.

[0037] The specific operation process is as follows: In this embodiment, taking the stranding of four welding wires as an example, one of the welding wires is selected as the main wire, and the other three are used as auxiliary wires for stranding. The main wire is wound around the wire feeding spool on the first fixed bracket (or directly select a wire feeding spool with the main wire wound on it), passes through the round hole in the middle of the sleeve, enters the main shaft, and exits from the second fixed bracket and enters the merging hole of the first stranding rod of the auxiliary wire strander. The other three auxiliary wires are respectively wound around the wire feeding spools of the first stranding wheel near one end of the first fixed bracket and are evenly distributed (the angle between each two wire feeding spools is 120°). The auxiliary wires pass through the adjacent hollow parts on the outer ring of the stranding wheel in the same direction (clockwise or counterclockwise), extend towards the second stranding wheel close to the second fixed bracket, then pass through the corresponding three holes (the angle between each two is 120°) in its inner ring and move towards the auxiliary wire strander on the second fixed bracket. After passing through the holes on the disc of the auxiliary wire stranding device, they are merged with the main wire at the merging hole, and driven by the small wire stranding end adjustable speed motor, the main shaft and the two fixed rotating wheels and the auxiliary wire strander on it are driven to rotate through the gear transmission method, so that the main wire and the auxiliary wires are stranded at the merging hole. Finally, the stranded finished product will be collected by the wire collecting wheel driven by the small wire collecting end adjustable speed motor. Similarly, by removing the above-mentioned main wire, a stranding method for three welding wires without a main wire can be achieved.

[0038] Taking the stranding of seven welding wires as an example, one of the welding wires is selected as the main wire, and the remaining six are used as auxiliary wires for stranding. The main wire is wound around the wire feeding spool on the first fixed bracket, passes through the round hole in the middle of the sleeve, enters the main shaft, and exits from the second fixed bracket and enters the merging hole of the first stranding rod of the auxiliary stranding device. For the other six auxiliary wires, three of them are respectively wound around the wire feeding spools of the first stranding wheel near one end of the first fixed bracket (the included angle between the wire feeding spools is 120°). The auxiliary wires pass through the adjacent hollow parts on the outer ring of the stranding wheel in the same direction (clockwise or counterclockwise), extend towards the second stranding wheel near the second fixed bracket, then pass through the corresponding three holes in its inner ring (the included angle between them is 120°) and move towards the auxiliary stranding device on the second fixed bracket. After passing through the holes on the disc of the auxiliary stranding device, they enter the merging hole of the first stranding rod of the auxiliary stranding device. The other three auxiliary wires are respectively wound around the wire feeding spools of the second stranding wheel near one end of the second bracket (the included angle between the wire feeding spools is 120°), and the positions of their wire feeding spools are in a staggered relationship with the spools on the first stranding wheel (the included angle between the six wire feeding spools is 60°). The auxiliary wires pass through the adjacent hollow parts on the outer ring of the second stranding wheel in the same direction as the auxiliary wires on the first stranding wheel, move towards the auxiliary stranding device on the second fixed bracket, and after passing through the holes on the disc of the auxiliary stranding device, they merge with the main wire and the other three auxiliary wires at the merging hole. Driven by the small stranding end adjustable speed motor and through the gear transmission method, the main shaft and the two fixed rotating wheels and the auxiliary stranding device on it are driven to rotate, so that the main wire and the auxiliary wires are stranded at the merging hole. Finally, the stranded finished product will be collected by the wire collecting wheel driven by the small wire collecting end adjustable speed motor.

[0039] Taking the stranding of thirteen welding wires as an example, one of the welding wires is selected as the main wire, and the remaining twelve are used as auxiliary wires for stranding. The main wire is wound around the wire feeding spool on the first fixed bracket, passes through the round hole in the middle of the sleeve, enters the main shaft, and exits from the second fixed bracket and enters the merging hole of the first stranding rod of the auxiliary wire strander. Six out of the other twelve auxiliary wires are respectively wound around the wire feeding spools of the first stranding wheel near one end of the first fixed bracket (the angle between the wire feeding spools is 60° for each pair). The auxiliary wires pass through the adjacent hollow parts on the outer ring of the stranding wheel in the same direction (clockwise or counterclockwise), extend towards the second stranding wheel near the second fixed bracket, then pass through the corresponding six holes in its inner ring (the angle between each pair is 60°) and move towards the auxiliary wire strander on the second fixed bracket. After passing through the holes on the disc of the auxiliary wire stranding device, they enter the merging hole of the first stranding rod of the auxiliary wire strander. The other six auxiliary wires are respectively wound around the wire feeding spools of the second stranding wheel near one end of the second bracket (the angle between the wire feeding spools is 60° for each pair). The positions of the wire feeding spools are in a staggered relationship with the spools on the first stranding wheel (the angle between the twelve wire feeding spools is 30° for each pair). The auxiliary wires pass through the adjacent hollow parts on the outer ring of the second stranding wheel in the same direction as the auxiliary wires on the first stranding wheel, move towards the auxiliary wire strander on the second fixed bracket, and after passing through the holes on the disc of the auxiliary wire stranding device, they merge with the main wire and the other six auxiliary wires at the merging hole. Driven by the adjustable-speed motor at the small wire stranding end and through the gear transmission method, the main shaft and the two fixed rotating wheels and the auxiliary wire strander on it are driven to rotate, so that the main wire and the auxiliary wires are stranded at the merging hole. Finally, the stranded finished product will be collected by the wire collecting wheel driven by the adjustable-speed motor at the small wire collecting end.
