切点跟踪磨削是提高汽车凸轮制造精度的一种重要加工手段。某型号凸轮磨削时发现砂轮架切点跟踪时机床振动噪声较大,并且对凸轮磨削质量有很大的影响。本文针对该磨床工作过程中出现的砂轮架振动过大、噪声较大等问题通过对砂轮架模态测试、响应测试、砂轮架各工况下振动测试等原型试验方法,探明砂轮架非正常工作的根本原因与解决方案。 Tangent point tracking grinding is to improve the manufacturing precision of the car cam is an important processing means. When a certain type of cam grinding is found, the vibration and noise of the machine tool is large when the grinding wheel frame is tangent point tracking and has a great influence on the quality of the cam grinding. In this paper, the grinder appeared during the work of the wheel frame vibration is too large, noise and other issues through the modal testing of the wheel frame, the response test, the vibration test under various conditions of the wheel frame and other prototype test methods to prove the wheel frame is not normal The root cause of work and solutions.
