Description
技术领域technical field
本发明涉及轴承套圈滚道加工设备,具体是一种卧式双主轴轴承套圈磨床。The invention relates to bearing ring raceway processing equipment, in particular to a horizontal double-spindle bearing ring grinding machine.
背景技术Background technique
轴承是当代机械设备中一种重要零部件。它的主要功能是支撑机械旋转体,降低其运动过程中的摩擦系数,并保证其回转精度。在机械设备的运行过程中,尤其是一些重要设备的运行过程中,对轴承进行定期检修和维护更换是保证设备正常运转的必要手段,在某些特殊情况下,出于对设备整机性能的保证,甚至要求定期对设备上的同一型号的轴承全部更换,这就要求对这些轴承的使用寿命有一个较为合理的预测,而对整批轴承的使用寿命进行预测时,整个批次的同型轴承之间,各项指标具有高度的一致性才能保证预测结果的合理有效。Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the operation of mechanical equipment, especially during the operation of some important equipment, regular maintenance and replacement of bearings is a necessary means to ensure the normal operation of the equipment. It is even required to replace all the bearings of the same type on the equipment on a regular basis. This requires a reasonable prediction of the service life of these bearings. When predicting the service life of the entire batch of bearings, the same type of bearings in the entire batch In order to ensure the reasonable and effective prediction results, the indicators have a high degree of consistency.
在轴承内圈的磨削加工中,内圈滚道的半精磨和精磨加工对保证内圈滚道的一致性有着决定性作用。现有的内圈滚道磨床,包括数控内圈滚道磨床,基本都采用单一主轴的加工方式,在对轴承套圈批次加工时,一台机床对应某一固定的工序,半精磨和精磨是分开的,这样加工效率高;但反映到轴承内圈滚道的一致性时,由于不同的机床之间存在装夹误差和磨头尺寸外形之间的误差,即使加工出的合格产品之间,也必然存在一些细小的差距,从而影响到整批产品的一致性。In the grinding process of the inner ring of the bearing, the semi-finishing and fine grinding of the inner ring raceway play a decisive role in ensuring the consistency of the inner ring raceway. Existing inner ring raceway grinders, including CNC inner ring raceway grinders, basically use a single spindle processing method. When batch processing of bearing rings, one machine tool corresponds to a fixed process, semi-finishing and The fine grinding is separated, so the processing efficiency is high; but when reflecting the consistency of the bearing inner ring raceway, due to the clamping error and the error between the size and shape of the grinding head between different machine tools, even if the qualified product is processed There must be some small gaps between them, which will affect the consistency of the entire batch of products.
目前,国内对内圈滚道的加工中,较为先进的是采用自动流水线的加工方式,但其半精磨和精磨两个工序也分别在不同的设备上完成,其中也必须经过两次上下料和两次装夹,不论其装夹定位机构有多精密,二次装夹过程中仍必然存在一定的定位误差,这就造成内圈滚道表面外形尺寸的一致性较差,即使经过超精,也无法彻底消除这种不一致的现象,从而影响轴承装配后的整体质量,生产出的轴承整体一致性也不是很好,从而影响对轴承寿命的预判。At present, in the domestic processing of the inner ring raceway, the more advanced processing method is the use of automatic assembly lines, but the two processes of semi-finishing and fine-grinding are also completed on different equipment, which must also go through two up and down processes. No matter how precise the clamping and positioning mechanism is, there must still be a certain positioning error during the second clamping process, which results in poor consistency of the outer dimensions of the inner ring raceway surface. It is impossible to completely eliminate this inconsistency, thus affecting the overall quality of the bearing after assembly, and the overall consistency of the produced bearing is not very good, thus affecting the prediction of bearing life.
