[0003] As disclosed in the winding machine for motor coils with the publication number CN109038982B, in the prior art, there are various specifications of coils. When replacing winding molds with different radial and axial dimensions, different mounting shafts or pressing blocks need to be replaced simultaneously, which is cumbersome to operate and has a high labor intensity, resulting in low processing efficiency of motor coils. To solve such problems, the present application proposes a winding mechanism with a new structure. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a winding mechanism for motor coils with a high slot fill factor.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A winding mechanism for motor coils with a high slot fill factor includes a machine base. One end of the machine base is connected by a coupling to a hollow rotating rod for rotational winding. A winding mold for winding is sleeved on the outer side of the rotating rod. Support plates are provided at the top and bottom of the rotating rod. On one side of the two support plates, a plurality of convex blocks for clamping the winding mold from the inside to the outside are fixedly connected. A plurality of connecting plates are fixedly connected to the inner wall of the rotating rod. A plurality of sliding grooves corresponding to the connecting plates are opened at the top and bottom of the rotating rod. Avoidance grooves are opened on one side of the plurality of connecting plates. Two racks are provided in the avoidance grooves. The two racks respectively pass through the sliding grooves and are fixed to the two support plates. A power component for driving the racks to move is provided in the rotating rod.

[0007] As a further scheme of the utility model, the power component includes a fixing plate. The fixing plate is fixedly connected inside the rotating rod. A motor is fixedly connected to one side of the fixing plate. One end of the output shaft of the motor passes through the fixing plate and is connected by a coupling to a connecting shaft. The connecting shaft passes through a plurality of connecting plates and passes between two opposing racks. A gear is key-connected to the circumferential outer wall of the connecting shaft at a position between the two opposing racks, and the gear meshes with the racks.

[0008] As a further solution of the utility model, two telescopic rods are fixedly connected to the top and bottom of each of the plurality of connecting plates, and one end of the telescopic part of the telescopic rod passes through the sliding groove and is fixed to the support plate.

[0009] As a further solution of the utility model, rubber blocks are fixedly connected to the tops of the plurality of bumps.

[0010] As a further solution of the utility model, a plurality of heat dissipation holes are formed in the circumferential outer wall of the rotating rod near the machine base.

[0011] As a further solution of the utility model, two adjacent racks are in a state where the tooth blocks are opposite to each other.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Through the arrangement of the bumps, after the winding mold is sleeved on the outer side of the rotating rod, the two support plates are pushed to move in opposite directions through the rack, so that the bumps on the support plate support and clamp the winding mold from the inside of the winding mold, thereby fixing the winding mold. Therefore, when facing coils of different specifications, there is no need to replace different mounting shafts or pressing blocks, the operation is simple, convenient to use, and the efficiency of motor coil processing is improved.

[0014] 2. Through the arrangement of the rubber blocks, when the bumps support and clamp the winding mold, the rubber blocks can increase the friction between the bumps and the winding mold, so that the winding mold will not move easily, and the stability of the winding mold installation is improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] It should be noted that the terms "first", "second", etc. in the description, claims and the above-mentioned drawings of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. For the embodiments of the present application described herein, based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Referring to Figures 1 - 3 , a motor coil winding mechanism with a high slot fill factor, includes a machine base 1. One end of the machine base 1 is connected by a coupling to a hollow rotating rod 3 for rotational winding. A winding mold for winding the wire is sleeved outside the rotating rod 3. Support plates 7 are provided at the top and bottom of the rotating rod 3. On one side of each of the two support plates 7, a plurality of bumps 8 are welded to clamp the winding mold from the inside to the outside. A plurality of connecting plates 5 are welded to the inner wall of the rotating rod 3. A plurality of chutes 13 corresponding to the connecting plates 5 are opened at the top and bottom of the rotating rod 3. Avoidance grooves 11 are opened on one side of each of the plurality of connecting plates 5. Two racks 10 are provided in the avoidance grooves 11. The two racks 10 respectively pass through the chutes 13 and are fixed to the two support plates 7. A power assembly for driving the racks 10 to move is provided inside the rotating rod 3. The winding mold is sleeved outside the rotating rod 3, and then the power assembly is used to drive the two opposite racks 10 to move in opposite directions. The two opposite racks 10 will push the two support plates 7 to move in opposite directions. The support plates 7 will drive the bumps 8 to move, so that the bumps 8 support and clamp the winding mold from the inside of the winding mold, completing the installation of the winding mold. Since the winding mold is clamped and installed, it is not necessary to replace different mounting shafts or pressing blocks when facing coils of different specifications, the operation is simple, convenient to use, and the efficiency of motor coil processing is improved.

[0021] In the present utility model, the power assembly includes a fixing plate 4, which is fixed inside the rotating rod 3 by bolts. One side of the fixing plate 4 is fixed with a motor by bolts. One end of the output shaft of the motor passes through the fixing plate 4 and is connected to a connecting shaft 6 through a coupling. The connecting shaft 6 passes through a plurality of connecting plates 5 and passes between two opposing racks 10. A gear 14 is key-connected to the circumferential outer wall of the connecting shaft 6 at a position between the two opposing racks 10, and the gear 14 meshes with the rack 10. By driving the connecting shaft 6 to rotate with the motor, the connecting shaft 6 drives the gear 14 to rotate. The gear 14 drives the two opposing racks 10 to move in opposite directions through meshing with the rack 10. Both the top and bottom of the plurality of connecting plates 5 are fixed with two telescopic rods 12 by bolts, and one end of the telescopic part of the telescopic rod 12 passes through the sliding groove 13 and is fixed to the support plate 7. Rubber blocks 9 are bonded to the tops of the plurality of bumps 8. The rubber blocks 9 can increase the friction between the bumps 8 and the winding mold, so that the winding mold will not move easily, thereby making the installation of the winding mold more stable. A plurality of heat dissipation holes 2 are provided on the circumferential outer wall of the rotating rod 3 near the machine base 1. The heat dissipation holes 2 can dissipate the heat generated during the operation of the motor. The two adjacent racks 10 are in a state where the tooth blocks are opposite to each other.

[0022] Working principle: When in use, the winding mold is sleeved on the outside of the rotating rod 3, and then the connecting shaft 6 is driven to rotate by the motor. The connecting shaft 6 drives the gear 14 to rotate. The gear 14 drives the two opposing racks 10 to move in opposite directions through meshing with the rack 10. The two opposing racks 10 push the two support plates 7 to move in opposite directions. The support plate 7 drives the bump 8 to move, so that the bump 8 supports and clamps the winding mold from the inside of the winding mold, completing the installation of the winding mold. Since the winding mold is clamped and installed, it is not necessary to replace different installation shafts or pressing blocks when facing coils of different specifications. The operation is simple and convenient to use, improving the efficiency of motor coil processing.
