Description

Technical Field

[0001] This utility model relates to the field of motor winding technology, specifically to a motor coil winding device. Background Technology

[0002] An electric motor generates driving torque and serves as a power source for electrical appliances or various machines. Its main function is to convert electrical energy into mechanical energy. The coil of the motor is an important component of the motor, and the quality of the coil affects the power of the motor. In the production process of the motor coil, a winding device is required to wind the coil.

[0003] However, existing winding devices typically use a winding spool to wind the conductor. Since the diameter of the winding spool is fixed, it is difficult to wind coils of different sizes, which can lead to a narrowing of the application range of the winding device and poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a motor coil winding device. Through the structural design of the winding adjustment component, pneumatic push rod and conical column, coils of different diameters can be wound conveniently, solving the problem of difficulty in winding coils of different sizes.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a motor coil winding device, comprising a base, a winding adjustment assembly, and an arc-shaped limiting plate. A fixing frame is provided on the base, and a T-shaped column is rotatably mounted on the fixing frame. One end of the T-shaped column has three receiving slots. The winding adjustment assembly has three components, each including an arc-shaped support plate and a vertical rod. One end of the arc-shaped support plate has a fixing ring, and the bottom of the fixing ring has an arc-shaped pressure block. The outer surface of the bottom end of the vertical rod mates with the fixing ring, and the vertical rod is vertically positioned in the receiving slot. The fixing ring mates with the receiving slot, and a spring mates with the outer surface of the vertical rod. One end of the T-shaped column has a circular groove, and a pneumatic push rod is provided in the circular groove. The output end of the pneumatic push rod has a conical column.

[0007] Furthermore, the fixing frame has a through hole, and a bearing is fitted inside the through hole. The outer surface of the end of the T-shaped column away from the circular groove fits with the inner ring of the bearing. The end of the T-shaped column away from the circular groove passes through the through hole to the outside of the fixing frame. A motor is installed on the fixing frame, and the output end of the motor is connected to the end of the motor away from the circular groove.

[0008] Furthermore, the cone column is located on the center line of the three arc-shaped pressure blocks, and two sliders are provided on the outer surface of the cone column. Two grooves are opened in the circular groove, and the sliders and grooves cooperate with each other.

[0009] Furthermore, a mounting block is provided on one side of the fixing ring, one end of the mounting block is connected to one end of the arc-shaped support plate, and a pressure rod is provided at the bottom of the mounting block, with the bottom end of the pressure rod connected to the top of the arc-shaped pressure block.

[0010] Furthermore, a limiting groove and two guide grooves are provided on the arc-shaped limiting plate, and a limiting block and two guide blocks are provided at the end of the arc-shaped support plate away from the fixed ring. The limiting block and the limiting groove cooperate, and there is friction between the limiting block and the limiting groove. The guide block and the guide groove cooperate.

[0011] Furthermore, a lever is provided on the side of the arc-shaped limiting piece away from the limiting groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of the winding adjustment component, pneumatic push rod and conical column, uses the output end of the pneumatic push rod to push the conical column to squeeze the three arc-shaped pressure blocks, so that the three arc-shaped support plates move outward simultaneously with the conical column as the center line, thereby realizing the adjustment of the required winding coil size. This allows for convenient winding of coils of different diameters, making it easy to operate, with good applicability, enriching the application range of the device, and improving the winding efficiency of the device.

[0014] 2. This utility model, through the structural design of the arc-shaped limiting piece, moves on the arc-shaped support plate, causing the arc-shaped limiting piece to extend beyond the outer arc surface of the arc-shaped support plate, thus restricting one end of the arc-shaped support plate. This prevents the wire from coming off the outer surface of the arc-shaped support plate during the winding process, effectively limiting the wire, improving the winding effect of the device, and facilitating the removal of the coils on the three outer surfaces.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a motor coil winding device, including a base 1, a winding adjustment component 4, and an arc-shaped limiting piece 407. A fixing frame 2 is provided on the base 1, and a T-shaped column 3 is rotatably mounted on the fixing frame 2. A through hole is opened on the fixing frame 2, and a bearing is fitted in the through hole. The outer surface of the end of the T-shaped column 3 away from the circular groove 301 is fitted with the inner ring of the bearing, so that the T-shaped column 3 can rotate. The end of the T-shaped column 3 away from the circular groove 301 passes through the through hole to the outside of the fixing frame 2. A motor 7 is provided on the fixing frame 2, and the output end of the motor 7 is connected to the end of the motor 7 away from the circular groove 301, so as to provide power for the rotation of the T-shaped column 3. Three receiving slots 302 are opened at one end of the T-shaped column 3.

[0025] The winding adjustment assembly 4 has three parts. The winding adjustment assembly 4 includes an arc-shaped support plate 401 and a vertical rod 403. A fixing ring 402 is provided at one end of the arc-shaped support plate 401. An arc-shaped pressure block 406 is provided at the bottom of the fixing ring 402. An installation block is provided on one side of the fixing ring 402. One end of the installation block is connected to one end of the arc-shaped support plate 401, which can facilitate the connection between the fixing ring 402 and the arc-shaped support plate 401. A pressure rod 405 is provided at the bottom of the installation block. The bottom end of the pressure rod 405 is connected to the top of the arc-shaped pressure block 406, which can ensure the connection between the arc-shaped pressure block 406 and the fixing ring 402. The outer surface of the bottom end of the vertical rod 403 is fitted with the fixing ring 402. The vertical rod 403 is vertically set in the receiving groove 302. The fixing ring 402 is fitted with the receiving groove 302. A spring 404 is fitted on the outer surface of the vertical rod 403.

[0026] One end of the T-shaped column 3 has a circular groove 301, and a pneumatic push rod 5 is installed in the circular groove 301. The output end of the pneumatic push rod 5 is provided with a conical column 6. The conical column 6 is located on the center line of the three arc-shaped pressure blocks 406. Two sliders 601 are provided on the outer surface of the conical column 6. Two sliding grooves 3011 are opened in the circular groove 301. The sliders 601 and the sliding grooves 3011 cooperate to ensure that the conical column 6 moves stably horizontally in the circular groove 301.

[0027] In use, according to the required coil size, the pneumatic push rod 5 in the circular groove 301 is activated. The output end of the pneumatic push rod 5 pushes the conical column 6 to slide horizontally outward within the circular groove 301. This causes the front arc surface of the conical column 6 to abut against the inner arc surfaces of the three arc-shaped pressure blocks 406, simultaneously compressing the three arc-shaped pressure blocks 406. After being compressed, the arc-shaped pressure blocks 406 are transmitted to the fixing ring 402 via the pressure rod 405, causing the fixing ring 402 to slide upward within the circular groove 301 and compress the spring 404. The spring 404 contracts after being compressed, thus... The fixing ring 402 slides upward on the outer surface of the upright 403 and drives the arc-shaped support plate 401 to move upward, so that the three arc-shaped support plates 401 move outward simultaneously with the cone column 6 as the center line until the distance that the three arc-shaped support plates 401 move outward matches the required coil size. Then the pneumatic push rod 5 stops. Similarly, when it is necessary to wind a smaller size coil, the output end of the pneumatic push rod 5 drives the cone column 6 to retract into the circular groove 301. The rebound force generated by the compression of the three springs 404 causes the three arc-shaped support plates 401 to retract inward simultaneously.

[0028] The arc-shaped limiting piece 407 has a limiting groove 4071 and two guide grooves 4072. The arc-shaped support plate 401 is provided with a limiting block 4011 and two guide blocks 4012 at the end away from the fixing ring 402. The limiting block 4011 cooperates with the limiting groove 4071, and there is friction between the limiting block 4011 and the limiting groove 4071, which can realize the movement and locking of the arc-shaped limiting piece 407 on the arc-shaped support plate 401. The guide block 4012 cooperates with the guide groove 4072 to ensure the stability of the movement of the arc-shaped limiting piece 407 at one end of the arc-shaped support plate 401. A paddle is provided on the side of the arc-shaped limiting piece 407 away from the limiting groove 4071, which can push the arc-shaped limiting piece 407.

[0029] After adjusting the required coil winding size, push the levers on the three arc-shaped limiting plates 407 in sequence. Through the engagement of the limiting block 4011 with the limiting groove 4071 and the guide block 4012 with the guide groove 4072, the arc-shaped limiting plates 407 move on the arc-shaped support plate 401, causing the arc-shaped limiting plates 407 to extend beyond the outer arc surface of the arc-shaped support plate 401, thus restricting one end of the arc-shaped support plate 401. After the coil winding is completed, the output end of the pneumatic push rod 5 drives the cone 6 to retract towards the inner side of the circular groove 301, causing the three arc-shaped support plates 401 to retract inward simultaneously. This causes the outer surfaces of the three arc-shaped support plates 401 to separate from the inner surface of the coil. Then push the levers to make the outer surface of the arc-shaped limiting plates 407 flush with the outer arc surface of the arc-shaped support plate 401. Finally, remove the coil from the three arc-shaped support plates 401 to complete the winding of a single coil.
