砂轮不平衡是引起砂轮系统振动的主要原因之一。特别是随着高速磨削和高精度磨削的发展,对砂轮的平衡提出越来越高的要求,为此有必要在高速磨床或高精度磨床上采用砂轮动态平衡装置,以减小磨床振动,提高磨削质量。平衡块重心作螺旋扫描运动的砂轮动态平衡装置具有传动控制简单、便于机床改装的优点。本文论述这种螺旋扫描式砂轮动态平衡装置的平衡机理、平衡精度和平衡过程对磨床振动的影响,并提出了主要结构和传动参数的合理范围及计算公式。一、平衡机理螺旋扫描式砂轮动态平衡装置的原理如图1所示。它根据砂轮不平衡量与砂轮系统的振幅成正比,通过振动传感器、测量装置和指示装置来检测砂轮系统的振动,然后自动或
Wheel imbalance is caused by vibration of the wheel system is one of the main reasons. Especially with the development of high-speed grinding and high-precision grinding, higher and higher demands are placed on the balance of the grinding wheel. Therefore, it is necessary to adopt a wheel dynamic balancing device on a high-speed or high-precision grinding machine to reduce the vibration of the grinding machine , Improve the quality of grinding. Balance weight center of gravity spiral scanning movement of the wheel dynamic balance device with transmission control is simple, easy to machine modification advantages. This paper discusses the balance mechanism, the balance accuracy and the balance process on the vibration of the grinding machine, and proposes the reasonable range and the calculation formula of the main structure and transmission parameters. First, the balance of mechanism Spiral scanning wheel dynamic balancing device principle shown in Figure 1. It is proportional to the wheel imbalance and the amplitude of the grinding wheel system is proportional to the vibration sensor, measuring device and indicating device to detect the vibration of the wheel system, and then automatically or
