磨床砂轮动平衡中平衡块调整量计算方法研究

针对配有三个平衡块的磨床砂轮动平衡装置,根据磨床砂轮不平衡量的大小提出两种不同的平衡块调整量计算方法。三配平块移动平衡法解决了当砂轮初次动平衡或砂轮不平衡量较大时如何计算各平衡块目标角度的问题,摄动移块平衡法解决了当砂轮需要精确动平衡或砂轮在使用一段时间后需要再次动平衡时如何计算平衡块调整量的问题。最后通过实验验证了在磨床砂轮动平衡时采用上述两种方法能提高磨床砂轮的动平衡效率,降低磨床在砂轮动平衡过程中的启停次数。

Study on Calculation Method of Balance Block Quantity Adjustment During Dynamic Balance of Grinding Wheel

Aiming at the grinding wheel balance device equipped three balance blocks, according to the unbalance value of the grinding wheel puts forward two different calculation methods of the balance blocks quantity adjustment. When the grinding wheel is taking dynamic balance for the first time or the grinding wheel owns a lot of unbalance, the problem that how to calculate the target angle of the three balance blocks has been solved through the moving three balance blocks balancing method. When the grinding wheel needs to take precise dynamic balance or needs to take dynamic balance again after a period of time, the problem that how to calculate the quantity of the balance blocks adjustment has been solved through the perturbation moving the balance block balancing method. At last it is proved by experiments that using the two methods during the dynamic balance of the grinding wheel can improve the grinding wheel balancing efficiency and reduce the grinding machine start and stop times.
