The transition guide shaft is formed by assembling the guide sleeve, the position of the A-shaped flat key on the surface of the guide sleeve is consistent with that of the flat key of the rotating shaft, and the assembly can be easily completed, so that the assembly quality is ensured, and unnecessary risks caused by repeated assembly are reduced.
Description
Technical Field
The utility model relates to the technical field of permanent magnet motor assembly, in particular to a permanent magnet motor rotor assembly auxiliary tool.
Background
At present, when a permanent magnet rotor motor is assembled, as the rotating shaft exceeds the end part of the stator less, the rotating shaft is provided with a key slot and is provided with an A-shaped flat key, when the outer rotor is slowly approaching, the outer rotor can be attracted with the stator due to the action of magnetic force, the key slot on the inner side of the outer rotor can not accurately enter the position of the flat key on the shaft, and the assembly can be successfully completed after the position is repeatedly operated for many times, thereby wasting time and labor.
Disclosure of utility model
Aiming at the problems that in the prior art, the magnetic force acts on the stator to attract the stator in the process of installing the rotor, so that the key groove at the inner side of the outer rotor cannot accurately enter the position of the flat key on the shaft, and the assembly can be smoothly completed after repeated operation and position adjustment for many times, the utility model takes time and labor, and provides the following technical scheme:
Permanent magnet motor rotor assembly assists utensil includes:
The guide sleeve, the keyway has been seted up on the guide sleeve surface, the inside joint of keyway has an A flat key, installation screw has been seted up to guide sleeve one end.
Through the technical scheme, the problem that the assembly fails because the magnetic force cannot accurately align with the key slot on the rotating shaft when the rotor is close to the stator during assembly of the outer rotor motor is effectively solved, and the assembly quality and the work efficiency of the motor are effectively improved.
As an improvement of the technical scheme, the guide sleeve is made of a cylindrical member.
Through the technical scheme, the rotor can be sleeved in the mounting process more conveniently, and the rotor is assembled.
As the improvement of the technical scheme, the diameter of the installation screw hole is matched with the motor rotating shaft, and the inner wall is provided with an installation thread.
Through above-mentioned technical scheme, can be more convenient connect motor shaft and this device to the installation is emboliaed with the rotor more convenient.
The utility model has the beneficial effects that:
the transition guide shaft is formed by assembling the guide sleeve, the position of the A-shaped flat key on the surface of the guide sleeve is consistent with that of the flat key of the rotating shaft, and the assembly can be easily completed, so that the assembly quality is ensured, and unnecessary risks caused by repeated assembly are reduced.

Reference numerals: 1. a guide sleeve; 2. a key slot; 3. installing a screw hole; 4. a-type flat key.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments.
Examples
Permanent magnet motor rotor assembly assists utensil includes:
The guide sleeve 1 is provided with a key groove 2 on the surface of the guide sleeve 1, an A-shaped flat key 4 is clamped in the key groove 2, and one end of the guide sleeve 1 is provided with a mounting screw hole 3;
The guide sleeve 1 is screwed into the motor rotating shaft by using threads through the installation screw hole 3, and the A-shaped flat key 4 is installed inside the key groove 2 formed in the auxiliary tool, and as the A-shaped flat key 4 on the guide sleeve 1 is consistent with the motor rotating shaft in size, the two A-shaped flat keys 4 are calibrated on one line through the A-shaped flat key 4 or other tools, so that the rotor can be accurately sleeved on a motor shaft after the rotor is transited through the guide sleeve 1, and the assembly of the rotor is completed.
As an improvement of the technical scheme, the guide sleeve 1 is made of a cylindrical member, so that the guide sleeve can be sleeved into the rotor more conveniently during installation, and the assembly of the rotor is completed.
As the improvement of the technical scheme, the diameter of the installation screw hole 3 is matched with that of the motor rotating shaft, and the inner wall is provided with the installation screw thread, so that the motor rotating shaft can be more conveniently connected with the device, and the rotor can be more conveniently sleeved and installed.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting.
