[0034] In order to make the present invention more obvious and easy to understand, the preferred embodiments are described in detail below with reference to the accompanying drawings.

[0035] The present invention provides an expandable rectangular wire motor stator automatic twist forming apparatus, which is suitable for flexible automatic wire assembly, such as Figures 1-7 As shown, it includes a workbench 1-9, and a ring-shaped spindle device 6-1 is fixed on the workbench 1-9. A first rotary power device 1-1, a second rotary power device 1-2, a third rotary power device 1-3, a fourth rotary power device 1-4, a fifth rotary power device 1-5, a sixth rotary power device 1-6, a seventh rotary power device 1-7, and an eighth rotary power device 1-8 are sequentially installed on the workbench 1-9 around the ring-shaped spindle device 6-1. Each rotary power device is configured with a high-precision servo actuator (which can be a servo motor), and a small gear is arranged at the top of each rotary power device and connected with the rotating end of the servo actuator.

[0036] The ring-shaped spindle device 6-1 is composed of a plurality of rotatable and interconnected ring-shaped spindles, as shown in Figure 4 The ring-shaped spindle device 6-1 is connected with the forming die device 5-1 at one end, and is connected with a fan-shaped tooth at the other end. The fan-shaped tooth is horizontally sleeved outside the ring-shaped spindle. The pinions on the rotating power devices are respectively engaged with the fan-shaped teeth of different layers on the ring-shaped spindle device 6-1, so as to drive the ring-shaped spindle device 6-1 to rotate the forming die device 5-1. Since the corresponding fan-shaped teeth of each ring-shaped spindle are stacked at different heights, the pinions on the corresponding rotating power devices are also arranged at different heights and do not interfere with the fan-shaped teeth at other positions. That is, the thickness of the pinion corresponds to the thickness of the fan-shaped tooth.

[0037] The forming die device 5-1 includes a plurality of forming dies, and each layer of wire pairs of the rectangular wire motor stator winding corresponds to a forming die. A plurality of wire insertion grooves are arranged in the circumferential direction of each forming die and are connected with the ring-shaped spindle in a clamping groove manner (a boss 5-2 is arranged on each forming die, a recess 6-2 is arranged on each ring-shaped spindle, and the boss 5-2 is matched and clamped with the recess 6-2), and no fastener is required for replacement, which is convenient and fast.

[0038] The ring-shaped spindle is a cylindrical structure, and each ring-shaped spindle corresponds to a forming die and is used to drive the forming die to rotate along the circumferential direction of the rectangular wire motor stator. The ring-shaped spindles are positioned and stacked layer by layer by means of bearing shoulder.

[0039] The ring-shaped spindle device 6-1 is a layer-by-layer nested structure, and the torsional forming of 4-12 layers of rectangular wire motor stators can be satisfied by controlling the rotating power devices. Each layer of ring-shaped spindle has independent servo control and Z-axis matching, and the forming curve is adjustable. The ring-shaped spindle device 6-1 adopts coaxial nesting technology, and the bottom and top of each ring-shaped spindle are positioned by high-precision bearings 8-1, so as to ensure the rotation accuracy and stability of the ring-shaped spindle, as shown in Figure 5 .

[0040] A modular design is adopted, and different configurations can be selected according to the number of layers of the stator product rectangular wire. The ring-shaped spindle device 6-1 is arranged below, each rotating power device is uniformly arranged around the ring-shaped spindle device 6-1, and the rectangular wire motor stator is placed above the device of the application. Full consideration is given to human engineering, which is convenient for observation during debugging.

[0041] The torsional forming die is quickly replaced. The clamping groove type connection without fasteners is adopted between the forming die device 5-1 and the ring-shaped spindle device 6-1. When replacing, the forming die device 5-1 can be directly lifted, separated from the ring-shaped spindle device 6-1, and then taken out. Then, the forming die device 5-1 of other products is replaced, so as to meet the common line production requirements of different products, as shown in Figure 6 , Figure 7 .

[0042] Standardized design, each rotating power device, annular spindle device 6-1, insulation paper protection mechanism (i.e. lower end insulation paper protection mechanism 2-1 and upper end insulation paper protection mechanism 3-1), insulation paper protection mechanism power device, parts have interchangeability.

[0043] Each rotating power device corresponds to an annular spindle, which can independently drive a forming mold to rotate.

[0044] The lower end insulation paper protection mechanism 2-1 and the upper end insulation paper protection mechanism 3-1 share a plurality of Z-direction guide rails 7-1, that is, the lower end insulation paper protection mechanism 2-1 and the upper end insulation paper protection mechanism 3-1 can slide up and down along the plurality of Z-direction guide rails 7-1, ensuring the coaxiality of the upper and lower end insulation paper protection mechanisms, as shown in Figure 2 One end of the plurality of Z-direction guide rails 7-1 is fixed on the top periphery of the annular spindle device 6-1, and the other end of the plurality of Z-direction guide rails 7-1 is connected together through a fixed plate.

[0045] The lower end insulation paper protection mechanism 2-1 is arranged above the forming mold device 5-1, and the upper end insulation paper protection mechanism 3-1 is arranged above the lower end insulation paper protection mechanism 2-1. The lower end insulation paper protection mechanism 2-1 and the upper end insulation paper protection mechanism 3-1 are both provided with through holes. The through hole in the lower end insulation paper protection mechanism 2-1 allows the lower end of the workpiece to pass through, but the upper end of the workpiece cannot pass through; the through hole of the upper end insulation paper protection mechanism 3-1 allows the driving end of the inner support power device 4-1 to pass through.

[0046] In this embodiment, the driving end of the first upper end insulation paper protection mechanism Z-direction power device 3-2 and the second upper end insulation paper protection mechanism Z-direction power device 3-3 is connected to the upper end insulation paper protection mechanism 3-1, and the first upper end insulation paper protection mechanism Z-direction power device 3-2 and the second upper end insulation paper protection mechanism Z-direction power device 3-3 are both fixed on the fixed plate; the driving end of the first lower end insulation paper protection mechanism Z-direction power device 2-2 and the second lower end insulation paper protection mechanism Z-direction power device 2-3 is connected to the lower end insulation paper protection mechanism 2-1, and the first lower end insulation paper protection mechanism Z-direction power device 2-2 and the second lower end insulation paper protection mechanism Z-direction power device 2-3 are both fixed on the upper end insulation paper protection mechanism 3-1.

[0047] The Z-axis compensation mechanism is as follows: as shown in Figure 8 When the copper wire of the rectangular wire stator 9-1 is twisted and formed, the copper wire will be bent from a straight line A state to a B state, and there will be a height difference C from the A state to the B state. Therefore, during the twisting and forming process, the rectangular wire stator 9-1 needs to be lowered to compensate for the height difference C. As shown in Figure 9As shown, the rectangular wire stator 9-1 is placed on the lower end insulation paper protection mechanism 2-1 and positioned by the positioning key 2-5, as shown in Figure 11 When the first lower end insulation paper protection mechanism Z-direction power device 2-2, the second lower end insulation paper protection mechanism Z-direction power device 2-3 drives the lower end insulation paper protection mechanism 2-1 and the rectangular wire stator 9-1 to descend to compensate for the height difference C. When the lower end insulation paper protection mechanism 2-1 descends, the first upper end insulation paper protection mechanism Z-direction power device 3-2, the second upper end insulation paper protection mechanism Z-direction power device 3-3 drives the upper end insulation paper protection mechanism 3-1 to descend synchronously.

[0048] The lower end insulation paper protection mechanism 2-1 and the upper end insulation paper protection mechanism 3-1 have the same structure, as shown in Figure 10 As shown, both include a base plate 2-9 with a through hole in the middle, a positioning disc 2-7 and a rotating disc 2-8, the upper surface of the base plate 2-9 is provided with a circular groove matching the positioning disc 2-7 and the rotating disc 2-8, the positioning disc 2-7 and the rotating disc 2-8 are arranged in the circular groove of the base plate 2-9, and the positioning disc 2-7 covers the rotating disc 2-8. One end of the rotating disc 2-8 is provided with a handle passing through the side of the base plate 2-9, and by turning the handle, the rotating disc 2-8 rotates around the center of the base plate 2-9, and the positioning key 2-5 is arranged on the inner wall of the positioning disc 2-7. The bottom of the circular groove in the base plate 2-9 is uniformly provided with a plurality of paper protection tooth grooves located on the radius of the base plate 2-9, and each paper protection tooth groove is provided with a paper protection tooth 2-6, which can move along the radial direction of the base plate 2-9 in the paper protection tooth groove, and the outer side end of each paper protection tooth 2-6 is provided with a roller, and the center axis of the roller is perpendicular to the paper protection tooth 2-6. The disc surface of the rotating disc 2-8 is provided with a plurality of arc-shaped holes penetrating through, one end of the arc-shaped hole is close to the center of the rotating disc 2-8, and the other end is away from the center of the rotating disc 2-8. The rollers on each paper protection tooth 2-6 are respectively arranged in a corresponding arc-shaped hole, and the rotating disc 2-8 is rotated, the rollers move along the arc-shaped hole, thereby driving the paper protection tooth 2-6 to stretch and contract in the paper protection tooth groove along the radial direction of the base plate 2-9.

[0049] Through the Z-axis compensation mechanism, the rectangular wire of the motor stator winding is transformed from a straight line to a Z shape during the compensation forming process; in the insulation paper protection mechanism, an insulation paper protection tooth 2-6 needs to be inserted between each adjacent two wire slots, as shown in Figure 11 to avoid tearing of the insulation paper 9-2 during the forming process; the inner support mechanism 4-2 is used to expand the motor stator core before forming to prevent the core from deforming during forming.

[0050] The workpiece (i.e., rectangular wire stator 9-1) is placed on the lower insulating paper protection mechanism 2-1. A latch (i.e., positioning key 2-5) is embedded in the lower insulating paper protection mechanism 2-1 to position the workpiece. The lower insulating paper protection mechanism power unit 2-4 drives the insulating paper protection mechanism to insert the paper guard teeth 2-6 between each adjacent wire slot.

[0051] The first upper insulating paper protection mechanism Z-direction power unit 3-2 and the second upper insulating paper protection mechanism Z-direction power unit 3-3 drive the upper insulating paper protection mechanism 3-1 and the internal support mechanism 4-2 to descend to a preset position. The upper insulating paper protection mechanism power unit 3-4 drives the insulating paper protection mechanism to insert the paper guard teeth 2-6 between each adjacent wire slot. The internal support power unit 4-1 drives the internal support mechanism 4-2 to tighten the rectangular wire motor stator. The internal support mechanism 4-2 is located in the middle of the bottom of the upper insulating paper protection mechanism 3-1. The drive end of the internal support power unit 4-1 passes through the upper insulating paper protection mechanism 3-1 and connects to the internal support mechanism 4-2.

[0052] The first lower end insulating paper protection mechanism Z-direction power device 2-2 and the second lower end insulating paper protection mechanism Z-direction power device 2-3 drive the lower end insulating paper protection mechanism 2-1, the first upper end insulating paper protection mechanism Z-direction power device 3-2 and the second upper end insulating paper protection mechanism Z-direction power device 3-3 drive the upper end insulating paper protection mechanism 3-1, and the lower end insulating paper protection mechanism 2-1 and the upper end insulating paper protection mechanism 3-1 descend synchronously to insert the workpiece into the forming mold device 5-1.

[0053] The present invention can be adapted for automated loading by robots or truss manipulators and docked with production lines. The present invention is modular in design. As the number of rectangular wire layers in the motor stator increases, a forming model device 5-1, an annular spindle device 6-1, and a rotary power device can be added, enabling rapid adaptive modification of existing equipment.
