in the initial origin position, the lifting mechanism 10 drives the lifting positioning block 8 to ascend. The rotor 7 to be tested is placed on the lifting positioning block 8, and the rotor 7 to be tested is supported by the lifting positioning block 8. When the unbalance is tested, the lifting mechanism 10 drives the lifting positioning block 8 to descend, and the rotor 7 to be tested is pressed down onto the driving belt 11. During testing, the driving motor 12 rotates to drive the tested rotor 7 and the driven wheel 9 to rotate through the driving belt 11, and testing action is completed. After the test is finished, the driving motor 12 stops rotating, and the lifting mechanism 10 drives the lifting positioning block 8 to ascend, so as to drive the tested rotor 7 to ascend.
When the unbalance amount is measured, the rotation axis of the measured rotor 7 is supported on the support pendulum L5 and the support roller 13 of the support pendulum R6. When the measured rotor 7 rotates, a centrifugal force due to the unbalance amount acts on the backup roller 13. The vibration caused by the unbalance is further transmitted to the spring 14 and further to the piezoelectric sensor 15 through the left and right swing links 16. After the piezoelectric sensor 15 receives the vibration signal, the output current/voltage signal is transmitted to the electric control system, so that the electric control system can analyze and calculate the equivalent position and the equivalent value of the unbalance.
When the measured rotor 7 is measured to obtain the equivalent position and the equivalent value of the unbalance, the electric control system controls the de-weight mechanism L3 and the de-weight mechanism R4 to perform de-weight processing on the measured rotor 7. The Y-axis servo motor 18 will automatically move to the proper position according to the equivalent position of the unbalance, so as to drive the drill bit to be coaxial with the rotor to be de-emphasized. The drill driving motor 19 rotates to drive the drill to rotate for cutting. The X-axis servo motor 20 drives the whole mechanism to move so as to control the drilling depth of the drill bit and further control the weight removal value.
The weight removing mechanism is used for simultaneously stretching out the left mechanism and the right mechanism when removing the weight, the drill bit rotates to remove the weight in a weight removing direction, and the weight removing mechanism stretches out the drill bit to contact the rotor in the opposite direction of the weight removing, so that the drill bit is prevented from rotating in the weight removing direction, the rotor transversely shifts, and the weight removing is greatly out of control.
Fig. 5 is a two-sided test URR evaluation chart of the measured values of the present invention (an evaluation item for a balancing machine in the national standard for detecting the rate of reduction of the unbalance amount). The testing is according to the descriptive examination and evaluation of the balance machine of the national standard GB/T4201-2006/ISO 2953: 1999. By evaluating the figure, the dots and crosses both fall within the concentric circle of 95% URR, and thus the balancing machine can be considered to have reached 95% URR.
