The dynamic balancing machine is a typical mechatronic device, which can be divided into a mechanical body, a driving part and a transmission part, a signal collecting part, and a central processing unit, each of which performs its own functions and cooperates with each other. Then follow the manufacturer of the Vibratory Finishing Machine to find out how the dynamic balancing machine performs rotor dynamic balance detection.
The mechanical body is mainly divided into three parts: the bed body, the swing frame and the head box. It is used for the support of the rotor. The rotors of different weights and specifications need to be equipped with corresponding mechanical bodies to ensure the accuracy of the rotor dynamic balance and the safety of the operators. .
The drive section provides the power to rotate the rotor, and the drive section refers to the process shaft, link shaft or fixture required for the rotor to rotate.
The signal acquisition part is used for the collection and preliminary processing of the rotor vibration signal. It is divided into the speed collection and the centrifugal force. The balance machine first needs to measure the rotation speed of the workpiece to determine the magnitude of the centrifugal force. When the rotor rotates, it will cause the vibration of the mechanical part. The sensor collects the vibration signal and, after some processing, transmits it to the central processing unit.
The central processing unit is mainly divided into a main board, a filter board, an A/D acquisition card, and a passive backplane, which are used for conversion, screening, and calculation of the rotor vibration signal, thereby obtaining the phase and size of the rotor unbalance amount, and then displayed on the screen of the computer. on.
