Description

TECHNICAL FIELD

[0001] The present application relates to the field of assembly, in particular to a vertical assembly guide tool clamp for a magnetic suspension blower rotor. BACKGROUND

[0002] The magnetic suspension blower rotor adopts an active magnetic suspension bearing system, and realizes five-degree-of-freedom non-contact suspension through a high-precision sensor and a main controller. The suspension gap is extremely small. The rotor is directly connected with a high-speed permanent magnet motor and a precisely processed impeller, and is equipped with a protection bearing to prevent abnormal collision. The stator is integrated with an electromagnetic coil to form a stable suspension force field. In traditional manual assembly, due to the small operation space and low positioning accuracy, the rotor is prone to physical collision with other components in the motor shell, resulting in surface scratches, bearing damage or magnetic suspension system disorder. Not only the assembly efficiency is low, but also the equipment operation vibration, noise exceeding standard and long-term reliability decline may be caused.

[0003] The existing patent with publication number CN106625398B discloses an aero-engine rotor assembly method and device.

[0042] Step three, when the difference of any two first horizontal distance values is greater than the set difference threshold value, it indicates that the concentricity error of the motor housing 9 and the lifting ring 17 exceeds the allowable range, and further indicates that the motor housing 9 is not in the correct assembly position. The controller 26 starts the buzzer 27 to alarm and reminds the operator to repair, and ends the assembly operation; when the difference of any two first horizontal distance values is not greater than the set difference threshold value, it indicates that the concentricity error of the motor housing 9 and the lifting ring 17 is controlled within the allowable range, and further indicates that the motor housing 9 is clamped and fixed in the correct assembly position. Execute step four;

[0044] Step five, when the difference of any two second horizontal distance values is greater than the set difference threshold value, it indicates that the concentricity error of the rotor shaft 10 and the lifting ring 17 exceeds the allowable range, and further indicates that the rotor shaft 10 is not in the correct assembly position. The controller 26 starts the buzzer 27 to alarm and reminds the operator to repair, and ends the assembly operation; when the difference of any two second horizontal distance values is not greater than the set difference threshold value, it indicates that the concentricity error of the rotor shaft 10 and the lifting ring 17 is controlled within the allowable range, and further indicates that the rotor shaft 10 is clamped and fixed in the correct assembly position.

[0066] Specifically, after the horizontal degree of the lifting ring 17 is detected correctly, the driving motor 21 is started to make the lifting ring 17 rise to the outside of the calibration ring 8, and then a plurality of infrared distance sensors one 18 are started, since the center axes of the lifting ring 17 and the calibration ring 8 coincide, the distance between the inner wall of the lifting ring 17 and the outer wall of the calibration ring 8 is a standard value, and based on the standard value, the plurality of infrared distance sensors one 18 are zero-position calibrated, so as to improve the measurement accuracy of the infrared distance sensor one 18.
