Description

A three-phase asynchronous motor end cover punching device

technical field

The invention belongs to the technical field of motor processing equipment, and in particular relates to a three-phase asynchronous motor end cover punching device.

Background technique

Three-phase asynchronous motor is a kind of induction motor. It is a type of motor powered by simultaneous access to 380V three-phase AC power supply (phase difference 120 degrees). Since the rotor and stator of the three-phase asynchronous motor rotate in the same direction and different The rotational speed becomes rotation, and there is a slip, so it is called a three-phase asynchronous motor. After the stator is fed with current, part of the magnetic flux passes through the short-circuit ring and induces current in it. The current in the short-circuit ring hinders the change of the magnetic flux, resulting in a phase difference between the magnetic flux generated by the part with the short-circuit ring and the part without the short-circuit ring, thereby forming a rotating magnetic field. After energized and started, the electromotive force and current are induced between the rotor winding and the magnetic field, that is, the rotating magnetic field and the rotor have a relative speed, and interact with the magnetic field to generate electromagnetic torque to make the rotor rotate and realize energy conversion.

The prior art three-phase asynchronous motor end cap punching device has the following problems: 1. Most of the existing punching devices use electric telescopic rods to control the up and down movement of the drill bit, thereby punching the end cap. When the cover is put into the groove, it may not be able to fix the end cover well in the groove due to the difference in the specifications of the end cover. The cover cannot be used, which wastes materials; 2. The existing punching devices are all fixed and cannot be rotated. When the end cover is placed in the placement groove, the distance between the drill bit and the placement groove is relatively close, which may hinder the opening of the end cap. Putting it in, so that the end cap cannot be punched conveniently and quickly.

Preferably, the upper surface of the base is embedded with an end cap placement groove

Compared with prior art, the beneficial effect of the present invention is:

1. The three-phase asynchronous motor end cover punching device of the present invention manually operates the rotation of the rudder disc, and combines the mutual engagement of the gear and the teeth, thereby controlling the downward movement of the drill bit and performing the drilling operation on the end cover in the groove. If the end cover is not in the center or is not firmly fixed, the operation of turning the steering wheel may not be performed manually. After adjusting the end cover to a suitable position or fixing it firmly, then control the drill to move down, and turn the steering wheel slowly to control The speed of punching holes is improved, thereby improving the yield of punching holes and saving materials.

2. The three-phase asynchronous motor end cover punching device of the present invention is provided with a rotating seat at the bottom of the telescopic cavity. When the end cover needs to be put in, the front end bracket can be pushed to the right, so that the drill bit, motor, etc. take the telescopic cavity as the center of the circle. Turn 90 degrees to the right to prevent it from hindering the insertion of the end cap. After putting in, turn the front bracket back to punch the end cap, which is more convenient for the punching operation.
