Dynamic balancing machine accuracy fault detection and elimination method, the sensor is one of the most important accessories in a dynamic balancing machine, the collection and transmission of various data are completed by sensors. If a dynamic balancing machine is compared to a human body, the sensor can be regarded as a human eye. Due to the high degree of integration of the sensor, its reliability is very strong. The probability of sensor damage and burnout in the case of proper use of the dynamic balancing machine is not very high, but the phenomenon of sensor damage and burnout caused by human factors cannot be excluded.

In general, the fault after the sensor is damaged is very easy to judge. When the sensor is damaged, the most direct fault is that the dynamic balancer measures no data. If the above phenomenon occurs, it can be basically concluded that there is a problem with the sensor.

So what problems should we pay attention to when using the dynamic balancing machine? Which aspects should we start to check and troubleshoot after the dynamic balance machine measurement accuracy fails? In general, we can press the following steps to judge and exclude.

1. Firstly calibrate the dynamic balancing machine. The calibration procedure can be seen before the small series or the manual.
2. After the calibration is completed, the unbalanced amount of the workpiece is measured by the dynamic balancing machine system. For example, the left correction surface of the workpiece has an unbalanced amount of 20g at an angle of 100 degrees, and the right correction surface needs 30g at an angle of 150 degrees. Heavy, then find 2 10g weights as the verification weight, and add 2 10g weights to the left 100 degrees and the right 150 degrees, then measure the unbalance, if left The unbalanced amount increases the weight of about 10% of 10g, and the unbalanced amount on the right side increases the weight of about 10% of 10g, which indicates that the accuracy of the dynamic balancing machine meets the accuracy requirement, and the dynamic balancing machine has no problem. On the contrary, there is a fault in the equipment of the dynamic balancing machine, and the following five fault factors need to be repaired.

There are many factors affecting the accuracy of the dynamic balancing machine, which are roughly divided into the following aspects:
1. Human factors: The operator's operation of the balancing machine is improper, the calibration value or angle is deviated, and the calibration position is deviated from the calibration position.
2, balance the workpiece itself factor: the processed workpiece does not meet the production process requirements, the dynamic balance machine swing support position surface is unqualified
3, the mechanical part of the balance machine affects the balance accuracy, such as: the roller has beating, the surface of the roller is not smooth, the overall connection of the pendulum is not strong, the bed is unstable, etc. If there is a process tool, it is necessary to consider the influence of the tolerance of the tooling and the workpiece ( ≤0.03mm).
4. Sensor and sensor line factors: The piezoelectric sensor is damaged or the assembly is too tight, too loose, the speed sensor is damaged or the speed is not in accordance with the actual speed (in addition to the artificial mark in the belt type balance machine, there are also photosensitive points affecting the speed measurement), The sensor line is open or shorted.
5, software measurement factors: data acquisition card damage or other electronic components are damaged.

The above is how to check the dynamic balancing machine accuracy fault method introduction, have you learned? hope that it can help us!
