Various revolving bodies in engineering have various factors such as asymmetrical geometric shapes and the like due to uneven materials or blank defects, errors generated in processing and assembling, even design, so that centrifugal inertia force generated by each tiny mass point on the revolving bodies cannot be counteracted mutually when the revolving bodies rotate, the centrifugal inertia force acts on machinery and the foundation through a bearing to cause vibration, noise is generated, bearing abrasion is accelerated, the service life of the machinery is shortened, and destructive accidents can be caused in severe cases. For this purpose, the rotor must be balanced to the level of precision permitted for balancing, or to the extent that the amplitude of the mechanical vibrations thus generated falls within the permitted range.
The dynamic balance of the rotor is affected by the state that the motor magnetic shoe is assembled in the motor shell. Specifically, if the actual thickness of the motor magnetic shoe exceeds the design specification (the thickness is larger than the design specification or smaller than the design specification), the rotor is unbalanced due to insufficient balance weight after being installed in the motor shell; if the angle of the motor magnetic shoe is deviated when the motor magnetic shoe is installed in the casing, the assembly quality error can lead the gravity center of the rotor not to coincide with the rotation center line, the rotor can also be unbalanced, and the phenomenon of motor magnetic shoe breakage can also occur in severe cases.
Both of the above two cases are embodied in that, in the assembling process, the pressure for pressing the motor magnetic shoe into the motor housing is abnormal, that is, when the thickness of the motor magnetic shoe is too small, the pressing pressure of the magnetic shoe is too small, and when the thickness of the motor magnetic shoe is too large or the assembling angle is deviated, the pressing pressure of the magnetic shoe becomes large.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The press-fitting mechanism with the pressure detection function can be used for but not limited to pressing the motor magnetic shoe into the motor shell, and can detect the press-fitting pressure in real time in the press-fitting process, so that a worker can judge whether the press-fitting pressure is in a normal range, and further judge whether the motor magnetic shoe is a good product or a defective product after being installed into the motor shell.
As shown in fig. 1 to 3, the press-fitting mechanism with pressure detection of the present embodiment mainly includes: a shell 1 with an inner cavity, a pressure sensing element 2, a press fitting 4 and a connecting rod 3. Wherein, casing 1 mainly used installs or spacing to pressure sensing component 2 and connecting rod 3, specifically, pressure sensing component 2 fixed connection in the inner chamber of casing 1, and the one end of connecting rod 3 sets up in the inner chamber of casing 1, and this end of connecting rod 3 can move about but do not break away from the inner chamber in the inner chamber of casing 1, and the other end of connecting rod 3 sets up outside the inner chamber of casing 1 in order to be connected with the pressure equipment piece 4 that sets up outside the inner chamber. Because connecting rod 3 is connected (preferred fixed connection) with pressure equipment 4, can receive effort (pressure) from the motor magnetic shoe when pressure equipment 4, this effort can make pressure equipment 4 drive connecting rod 3 move in order to support on pressure sensing element 2 towards pressure sensing element 2, when pressure sensing element 2 received connecting rod 3 and supported the pressure, can collect and feed back this pressure to whether the personnel judge this assembled state is qualified.
