technical field

The invention relates to the technical field of packing equipment, in particular to a winding machine.

Background technique

Most of the existing high-speed permanent magnet motors use scattered stators. Due to the high power density of the motor, the number of parallel windings of the motor coils is often large. The main method used by the existing winding machines on the market for this kind of coil winding with a large number of parallel windings is to use a multi-head tension pay-off frame, and the multiple winding barrels are wound simultaneously. The principle is to use the winding machine to wind the equivalent parallel winding. The number of wires in the wire barrel are wound on the coil mold at the same time. Since the perimeter of the coil mold has been calculated in the design, the coil with the specified number and length can be obtained when the coil is taken off the mold. However, when the number of parallel coils exceeds 80, the use of the existing winding method on the market will result in a large area of the wire barrel, and a large number of spare wire barrels are required, which is very uneconomical.

Detailed ways

The solution will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a winding machine includes a frame, a screw rod assembly and a winding mechanism; the screw rod assembly and the winding mechanism are installed on the frame in parallel;

As shown in FIG. 3 , the rack includes a base plate 11 and four support plates 12 fixed on the base plate 11 . The screw rod assemblies are fixedly connected above the two support plates 12 on one side of the base plate 11 , and the screw rod assemblies are fixed on the other side of the base plate 11 . A winding mechanism is fixedly connected above the two support plates 12 . The support plate 12 is rigidly connected and fixed to the bottom plate 11 through screws.

As shown in Figures 2 and 4, the screw rod assembly includes a screw rod 21, a nut, a screw rod seat 22, a first sprocket 41 and a wire harness 23. The screw rod seat 22 is provided on the frame, and the screw rod 21 is fixed On the screw rod seat 22, the nut is installed on the screw rod 21, the wire harness 23 is installed on the nut, and the axial movement is realized as the screw rod rotates, and the first sprocket 41 is installed on one end of the screw rod 21; 32 is adjustable in the position of the winding barrel 31.

As shown in FIG. 5 , the winding mechanism includes a winding barrel 31 , a pair of wire clamps 32 , a drive shaft 33 , a steering wheel 34 , a second sprocket 42 and a belt seat bearing 35 , and windings are provided on the surface of the winding barrel 31 slot, the winding barrel 31 is fixed on the frame through the belt seat bearing 35, the wire clamp 32 is fixed on both sides of the winding barrel 31, the winding barrel 31 is driven to rotate by the steering wheel 34, and the steering wheel 34 is driven by interference fit. The shaft 33 is connected, the second sprocket 42 is installed on one end of the drive shaft 33 , and the first sprocket 41 and the second sprocket 42 are synchronously transmitted through the chain 43 . The winding grooves provided on the surface of the winding barrels 31 are spiral V-shaped grooves; the winding barrels 31 and the drive shaft 33 are connected with screws for positioning with a stop.

In this scheme, the copper wire ends drawn from the tension pay-off rack are fixed on one side of the wire clamp 32 through the wire tie 23, the direction wheel 34 is rotated to rotate the winding barrel 31, and the copper wire is pulled to make the copper wire wound around the winding At the same time, the second sprocket 42 drives the first sprocket 41 to rotate through the chain 43, so that the screw rod 21 rotates, so that the wire harness 23 moves axially along the screw rod 21 under the pulling force of the copper wire, Therefore, the copper wire will spirally advance on the winding barrel 31, so that the copper wire enters the spiral V-shaped groove opened by the winding barrel 31.
