The main function of the Huake Zhichuang dynamic balancing machine is to measure the size and position of the unbalance of a rotating object (rotor); The main performance of a dynamic balancing machine is based on two comprehensive indicators: the minimum achievable residual unbalance and the reduction rate of the dynamic balancing machine. The former is the minimum value of the residual unbalance that the balancing machine can achieve for the rotor, and it is an indicator of the highest balancing capacity of the balancing machine; The latter is the ratio of the reduced imbalance after one correction to the initial imbalance.

Method for verifying the measurement accuracy and precision of a dynamic balancing machine:

1. First, calibrate the balancing machine. Please refer to the instruction manual for the calibration steps. Assuming that the outer circle of the rotor is used as the calibration surface of the workpiece (to facilitate the verification of the accuracy of the balancing machine).

2. After the calibration is completed, use the balancing machine software to measure the imbalance of the workpiece. For example, if there is a 20g imbalance on the left side of the workpiece at an angle of 100 degrees that needs to be weighed, and a 30g imbalance on the right side at an angle of 150 degrees that needs to be weighed, find two 10g weights as verification test weights, add each 10g weight to the left side at 100 degrees and the right side at 150 degrees, and then measure the imbalance. If the imbalance on the left side increases by about 90% of the weight of 10g and the imbalance on the right side increases by about 90% of the weight of 10g, it means that the accuracy of the balancing machine meets the accuracy requirements and there is no problem with the balancing machine. On the contrary, if there is a malfunction in the balancing machine equipment, the above 5 fault factors need to be repaired.

Factors affecting the measurement accuracy and precision of dynamic balancing machines:

1. Software measurement factors: data acquisition card damage or other electronic component damage.

2. Need to balance the factors of the workpiece itself: the processed workpiece does not meet the production process requirements, and the surface of the balancing machine swing support position is not qualified

3. Human factors: Improper operation of the balancing machine by the operator, deviation in calibration values or angles, and deviation between the calibration position and the calibration position.

4. The mechanical part of the balancing machine affects the balancing accuracy, such as roller jumping, uneven roller surface, unstable connection of the swing frame as a whole, and unstable bed. If there are process fixtures, the influence of the fixture and workpiece fit tolerance (≤ 0.03mm) needs to be considered.

5. Sensor and sensor wire factors: piezoelectric sensor is damaged or assembled too tightly or loosely, speed sensor is damaged or the speed measurement does not match the actual speed (in addition to manual marking, there are also photosensitive points that affect speed measurement in the belt balancing machine), sensor wire is open or short circuited.
