[0021] like Figure 1As shown in Figure 6, a wind turbine coil winding machine includes an electric rotary table 1. A feed reduction gearbox 2 is installed at the top center of the electric rotary table 1. An AC cycloidal pinwheel reducer motor 3 is installed on one side of the outside of the feed reduction gearbox 2. A horizontal worm gear 4 is installed inside the feed reduction gearbox 2. The worm gear 4 is fixedly connected to the drive end of the AC cycloidal pinwheel reducer motor 3.
[0022] Above the worm 4, a worm wheel 5 and a gear a6 are installed in the feed reduction gearbox 2. The worm wheel 5 and the gear a6 are coaxial and mesh with the worm 4. A support seat 7 is installed on the top of the feed reduction gearbox 2. A horizontal transmission shaft 8 is installed inside the support seat 7. A gear b9 is fixed on the transmission shaft 8 and meshes with the gear a6.
[0023] A winding mold 11 arranged horizontally is provided above the support base 7. A connecting plate 10 is fixed on the drive shaft 8. The connecting plate 10 is fixedly connected to the bottom of the winding mold 11 by a cross key.
[0024] A wire feeding roller frame 12 is provided on one side of the electric rotary table 1. Three sets of roller frames 13 that serve as angle guide accessories are installed on the top of the wire feeding roller frame 12. The roller frames 13 are arranged in a straight line on the wire feeding roller frame 12 and are evenly spaced. Each roller frame 13 is provided with two rollers 1301 arranged horizontally or two rollers 1301 arranged inclined vertically.
[0025] In the axial direction of the drive shaft 8, an electrically controlled travel limit switch 14 is installed on the upper ends of both sides of the feed reduction gearbox 2; the orientation of the drive shaft 8 and the worm wheel 5 shaft is consistent with the length direction of the winding mold 11, and the worm 4 and the worm wheel 5 shaft are arranged in a cross shape.
[0026] This wind turbine coil winding machine is a specialized piece of equipment customized according to the process requirements of the motor coil branch and the motor factory. It is mainly used for reciprocating winding of wind turbine coils at angles of 45 to 90 degrees. During operation, the output end of the AC cycloidal pinwheel reducer motor 3 drives the worm gear 4 to rotate under the support of bearings at both ends. Simultaneously, the worm gear 4 drives the worm wheel 5 to rotate, which in turn drives its axle and gear a6 to rotate together under the support of bearings at both ends. Gear a6 drives the meshing gear b9. The gear 9 rotates, and its axle rotates under the support of the bearings at both ends. The axle of the gear 9 rotates through the connecting plate 10 fixed to it, which in turn drives the winding mold 11 to rotate. In this way, the speed is reduced by an AC cycloidal pinwheel reducer motor 3, and the direction is changed by the transmission between the worm gear 5 and the worm 4 in the feed reducer 2 and the transmission between gear a6 and gear b9, which drives the transmission shaft 8 and the winding mold 11 to rotate. By electrically controlling the two sets of travel limit switches 14, the winding mold 11 can oscillate back and forth within the working angle between 0 degrees and 90 degrees and between 90 degrees and 180 degrees. Then, the rotational motion of the electric rotary table 1 is coordinated with the three-dimensional spatial curve fitting to realize the winding process of this special coil.
[0027] Because the angle of the wire bar needs to be changed during the winding process, a roller frame 13 that acts as an angle guide accessory is added to the wire feeding roller frame 12. The horizontally placed wire bar is converted to 90-degree winding through two reversals by three sets of split roller frames 13 to ensure the normal winding process.
[0028] The electrical control box of the equipment is installed on the table of the electric rotary table 1. Two sets of operation buttons are also provided at both ends of the winding mold 11. The rotation control of the electric rotary table 1 is achieved by a foot switch, which is convenient for the operator. All the power supply on the upper part of the table of the electric rotary table 1 is supplied by through-hole conductive slip rings. The slip rings are installed at the bottom of the main shaft of the electric rotary table 1 and are powered by carbon electrodes, allowing for 360° continuous and unrestricted rotation to ensure the power supply requirements for operation.
[0029] The main shaft of the electric rotary table 1 of the wind turbine coil winding machine adopts a hollow shaft structure. The bottom end of the main shaft is equipped with a conductive slip ring and carbon brush for power supply of the swing reduction gearbox and signal circuit on the rotary table, so as to achieve unobstructed operation of the power supply for rotating power. The electric rotary table 1 consists of a worktable, a worktable base and a gearbox. The worktable is driven to rotate by a main motor, and stepless speed regulation can be achieved through electrical means. The wire feeding roller frame 12 is arranged longitudinally on the outside of the electric rotary table 1. Three sets of roller frames 13 are installed on it. Through the action of two rollers 1301 in each set of roller frames 13, pressure is applied to the copper wire busbar in both vertical and inclined directions to straighten the copper wire busbar and play a guiding role.
