摘要:
以TX1600G数控镗铣加工中心为例,主要研究在移动热源施加条件下,不同的进给速度以及冷却液流量对系统热平衡的影响。为得到滚珠丝杠在实际工作中的状态,利用ANSYS建立丝杠的简化三维模型,施加移动热源来模拟螺母和轴承的传动热量,从而得到丝杠的温度模型,建立热误差补偿模型。结果表明,进给速度的增加可以缩短系统的热平衡时间,但热平衡温度有所升高; 冷却液可以有效地降低热平衡温度和缩短热平衡时间。热误差模型建立和温度场分析,为系统的热补偿提供必要的理论依据。
Abstract:
This paper takes TX1600G CNC boring and milling machining center as example and mainly studies the impact of different feed speed and coolant flow on the system heat balance, under the conditions of the moving heat source. To understand the ball screw in actual working conditions, ANSYS was first used to establish a simplified three-dimensional model of the ball screw, and then the heat source was moved to simulate heat transmission on nut and bearing, so the temperature model and thermal error compensation model of lead screw are established. Results show that the increase of feed speed can shorten the time for heat balance of the system, but the thermal equilibrium temperature was increased; coolant fluid can effectively reduce the thermal equilibrium temperature and the thermal equilibrium time. Thermal error modeling and the analysis of temperature field also provide necessary theoretical basis to the thermal compensation of the system.
