Technical Field
[0001] The utility model relates to the technical field of rotor winding, in particular to a disc structure of a rotor winding machine for fixing a rotor. Background Art
[0002] The rotor is a rotating part in an electric motor. The electric motor consists of two parts, a rotor and a stator. It is a device for converting electrical energy into mechanical energy and vice versa. The motor rotor is divided into a motor rotor and a generator rotor. During the assembly process of the rotor, winding needs to be carried out on the rotor. The existing rotor installation methods of rotor winding machines are mostly fixed clamping. Since the winding part of the rotor has a certain width, but due to the fixed position, there will be problems such as too thick and uneven winding. In addition, the existing fixing method during rotor winding easily causes the rotor to swing, resulting in an unsatisfactory winding effect. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is a disc structure of a rotor winding machine for fixing a rotor, which is convenient for installing the rotor, can make the winding uniform, and has a good fixing effect.

A transmission area is arranged inside the outer frame, which is used to drive the rotor body to displace and rotate. A power area is arranged inside the outer frame below the transmission area to provide power for displacement and rotation. A partition is arranged between the transmission area and the power area. Above the partition is a rectangular base, which can slide on the partition. Telescopic rods are fixed between both sides of the rectangular base and both inner sides of the outer frame to drive the rectangular base to displace. Above the rectangular base is a rotating disc. In the middle of the upper surface of the rotating disc is fixed a fastening groove one for clamping the rotor body. A through hole is opened in the middle of the rectangular base, and a spline through hole one is opened in the middle of the partition. A motor is arranged in the power area. In the middle of the lower side of the rotating disc is fixed a transmission shaft, and the other end of the transmission shaft passes through the through hole and the spline through hole one and is fixedly connected to the output end of the motor. On both sides in the power area are respectively fixed a telescopic control device and a motor control device to respectively control the telescopic displacement and the rotation angle. A spline through hole two is opened in the middle of the top surface of the outer frame for limiting the rotor body. On one side of the top of the outer frame is fixed a support arm, and on one side of the top of the support arm is opened a telescopic sleeve to facilitate the telescopic movement of the locking structure. A locking structure is arranged in the telescopic sleeve. The locking structure includes a telescopic block. A round hole is opened on the upper side of the telescopic block, and a cylindrical groove is opened on the inner side of the round hole. A lock head is slidably connected in the cylindrical groove. A round table is fixed on the side of the lock head, and a tension spring is fixed between the round table and the cylindrical groove to pull the lock head downward. A fastening groove two is opened on the lower side of the lock head for clamping the rotor body. The rotor body is clamped between the fastening groove one and the fastening groove two.
[0005] First, insert the bottom end of the rotor body into the through hole and the first spline through hole, and fix it in the first fastening groove. Then, pull the lock head to fasten the top end of the rotor body in the second fastening groove. Pulling the lock head will tighten the tension spring. When it is fixed, release the lock head, and the tension spring will return to the tightened state. When winding the wire, the telescopic rod will push the rectangular base to move. The rectangular base will drive the rotating disc and the motor to displace, and at the same time, it will also drive the rotor body to displace in the second spline through hole, making the winding more uniform.
[0006] Both of the telescopic rods are connected to the telescopic control device.
[0007] The motor and the motor control device are both electrically connected to an external power source.
[0008] The minimum width of the first spline through hole and the second spline through hole is equal to the minimum diameter of the rotor body.
[0009] The transmission shaft slides in the first spline through hole.
[0010] One end of the telescopic block is inserted into the telescopic sleeve.
[0011] One end of the tension spring is fixed under the frustum, and the other end of the tension spring is fixed on the bottom surface of the cylindrical groove.
[0012] A number of small sliding beads are inlaid at the edge of the bottom surface of the rotating disc, and the number of the small sliding beads is in contact with the top surface of the rectangular base, reducing the rotation resistance.
[0013] The advantages of the present utility model compared with the prior art are as follows: The present utility model adds a telescopic rod structure, which can drive the rotor to move, so that the winding is more uniform.
