Description

Technical Field

[0001] The utility model belongs to the technical field of winding machine accessories, in particular to a clamping device of a clamping shaft winding machine. Background Art

[0002] The motor is an important device for realizing the mutual conversion between electrical energy and mechanical energy. It usually includes a rotor and electrons. The rotor is usually composed of an iron core, a winding (copper wire) and a shaft. Among them, the winding is the key part of the rotor. The magnetic field is generated in the winding by electric current, which interacts with the magnetic field of the stator to realize the rotation of the motor.

[0003] With the development of science and technology, the winding of copper wire on the rotor has evolved from the initial manual winding, to the later mechanical winding, and then to the current automated winding equipment (i.e., clamping shaft winding machine), which has greatly improved the efficiency and performance of rotor production.

[0004] In traditional shaft winding machines, clamps are usually used to fix the rotor. For example, Chinese patent application No. (CN202011616777.2) discloses a feeding device for a micromotor rotor winding machine. The application fixes the rotor through clamps, while traditional clamps are usually pulled to clamp the shaft on the rotor. For example, Chinese patent application No. (CN201720547357.0) discloses a locking device, in which a pull rod pulls the clamp to clamp the shaft. However, this method is carried out by pulling the clamp. When the clamp contracts radially, axial movement will occur, which can easily cause the height of the rotor to change, affecting the regularity of the copper wire winding on the rotor and the quality of the rotor, which needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping device for a clamping shaft winding machine in view of the above-mentioned technical problems, so as to achieve the effect of preventing the rotor from being displaced in the axial direction when being clamped and fixed.

[0007] Base, mounted on the workbench;

[0008] The clamping claw is coaxially mounted in the base, and the top end extends out of the base to form a plurality of claw heads;

[0009] A sleeve is coaxially sleeved on the surfaces of the plurality of claw heads and is provided with a necking section for radially clamping and resetting the plurality of claw heads;

[0023] The synchronous belt is connected between the synchronous wheel and the second driving member, and is used for the linkage between the output end of the second driving member and the synchronous wheel.

[0024] In the above technical solution, further, it also includes:

[0025] A first connecting block connected to the bottom end of the pull rod;

[0026] A second connecting block connected to an output end of the first driving member;

[0027] Wherein, the second connecting block is rotatably connected to the first connecting block.

[0035] In the above technical solution, further:

By setting the third driving member and the second support plate, and coordinating the clearance between the base and the workbench, the height of the base (i.e., the height of the clamping claw) can be adjusted to ensure that rotors with different shaft lengths can be effectively clamped and fixed, thereby improving applicability.
