Technical Field

[0001] The utility model relates to a motor rotor, in particular to a winding machine for motor rotor coils. Background Art

[0002] A motor consists of two parts, a rotor and a stator. The motor rotor is the rotating part in the motor. It is a device used to realize the conversion between electrical energy and mechanical energy and between mechanical energy and electrical energy. The motor rotor is divided into a motor rotor and a generator rotor. Most electrical products need to be wound with enameled copper wires into inductance coils, so a winding machine is required.

[0003] After retrieval, the patent with the publication number CN220605737U discloses "a winding machine for motor rotor coils". This patent mainly clamps and fixes the rotor through a fixing plate, a driving motor, an electric telescopic rod and an arc-shaped clamping plate. However, it can only wind the rotor with a fixed size, and the winding position is fixed, and it is impossible to evenly wind the copper wire in the winding groove of the rotor. Summary of the Invention

[0004] The purpose of the utility model is to provide a winding machine for motor rotor coils, which can clamp rotors of different sizes, and can drive the rotor to rotate and move successively, improving the winding effect. At the same time, the structure is simple, convenient and practical, and is convenient for installation and use.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: to provide a winding machine for motor rotor coils, including a base. A mounting plate is fixedly installed at the center of the top of the base. A turntable is movably connected to the front of the mounting plate. A clamping component is fixedly connected to the front of the turntable. The clamping component includes a mounting table. A U-shaped chute is opened on the front of the mounting table. A bidirectional lead screw is installed inside the U-shaped chute. The left end of the bidirectional lead screw extends to the outside of the mounting table. A hand wheel is fixedly connected to the left end of the bidirectional lead screw. The outer surface of the bidirectional lead screw is threadedly connected with sliders. The number of the sliders is two. The bottoms of the two sliders are semi-circular. The two sliders are located inside the U-shaped chute. The surfaces of the two sliders are fixedly connected with retaining pieces. A mounting column is fixedly connected to the left side surface of the right retaining piece. A rotor is installed on the outer surface of the mounting column.

[0006] Optionally, a rotating groove is opened on the front of the mounting table. The rotating groove is located at the left end of the U-shaped chute.

[0007] Optionally, a rotating shaft is fixedly connected to the center of the back of the turntable. The rotating shaft penetrates through the mounting plate and extends to the rear of the mounting plate. A first bevel gear is fixedly connected to the outer surface of the rotating shaft.

[0008] Optionally, a motor is fixedly connected to the top of the base, a second bevel gear is fixedly connected to the output end of the motor, and the second bevel gear is meshingly connected to the first bevel gear.

[0009] Optionally, a connection block is fixedly connected to the back of the turntable, and there are multiple connection blocks, and fan-shaped blocks are fixedly connected to the bottoms of the multiple connection blocks.

[0010] Optionally, an annular groove is provided inside the mounting plate, and a plurality of the sector blocks are movably connected inside the annular groove.

[0011] Optionally, a pulley is fixedly connected to the bottom of the base, and the number of the pulleys is four.

[0012] Optionally, a platform is installed at the bottom of the base, and a roller slide groove is opened on the top of the platform. The number of the roller slide grooves is two, and four pulleys are respectively installed inside the two roller slide grooves.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the clamping part, motor, first bevel gear, second bevel gear, pulley, roller slide, turn the hand wheel to rotate the bidirectional screw during use, and the left slider will move to the left under the limit of the U-shaped slide. When the left slider moves to the rotating groove, turn the left slider to dislocate the left slider to provide space for placing the rotor. After the rotor is inserted into the mounting column, reset the left slider, and then reverse the hand wheel to reverse the bidirectional screw. The two sliders move close to each other under the limit of the U-shaped slide. The baffles on the two sliders will firmly fix the rotor, and then fix the copper wire in the winding groove of the rotor. The motor starts working, and the output end of the motor drives the second bevel gear. The gear rotates, and the second bevel gear then drives the first bevel gear to rotate. The first bevel gear drives the turntable to rotate through the rotating shaft, thereby rotating the rotor, allowing the copper wire to be wound in the winding groove of the rotor. At the same time, the base can be pushed to allow the pulley to move in the roller slide groove on the platform, so that the copper wire can be wound more evenly. Compared with the existing device that can only wind rotors of fixed sizes and the winding position is fixed, and the copper wire cannot be evenly wound in the winding groove of the rotor, the device can clamp rotors of different sizes and can drive the rotor to rotate and move forward and backward, thereby improving the winding effect. At the same time, the structure is simple, convenient and practical, and easy to install and use.

[0015] 2. Through the turntable, sector blocks and annular grooves, the rotating turntable drives multiple sector blocks to slide in a circle inside the annular groove during use, reducing the shaking caused by the rotation of the shaft, ensuring the stability of the turntable during rotation, making the rotor more stable during rotation, and improving the winding effect.

[0032] Working principle: During use, rotate the handwheel 404 to make the bidirectional lead screw 403 rotate. The left slider 405 will move leftward under the limitation of the U-shaped chute 402. When the left slider 405 moves to the rotating groove 409, rotate the left slider 405 to misalign it, providing space for placing the rotor 408. After sleeving the rotor 408 onto the mounting post 407, reset the left slider 405. Then reverse the handwheel 404 to make the bidirectional lead screw 403 reverse. The two sliders 405 move closer to each other under the limitation of the U-shaped chute 402. The retaining pieces 406 on the two sliders 405 will firmly fix the rotor 409. Then fix the copper wire in the wire winding groove of the rotor 408. The motor 7 starts to work. The output end of the motor 7 drives the second bevel gear 8 to rotate. The second bevel gear 8 then drives the first bevel gear 6 to rotate. The first bevel gear 6 drives the turntable 3 to rotate through the rotating shaft 5, thereby making the rotor 408 rotate and winding the copper wire around the wire winding groove of the rotor 408. At the same time, the base 1 can be pushed to make the pulleys 12 move in the roller chutes 14 on the platform 13, making the copper wire winding more uniform.
