技术领域 technical field
本发明属于测试技术领域，涉及轴承套圈测量装置，具体涉及一种轴承内外套圈圆度测量装置。 The invention belongs to the technical field of testing, and relates to a measuring device for bearing rings, in particular to a measuring device for roundness of inner and outer rings of a bearing.
背景技术 Background technique
内外套圈的圆度是轴承的重要结构参数之一，影响轴承的装配精度，产生由装配带来的预应力，改变滚动轴承游隙，进而影响轴承受载情况下的载荷分布，最终影响轴承的疲劳寿命。 The roundness of the inner and outer rings is one of the important structural parameters of the bearing, which affects the assembly accuracy of the bearing, generates prestress brought by assembly, changes the clearance of the rolling bearing, and then affects the load distribution of the bearing under load, and finally affects the bearing. fatigue life.
目前在生产线上的轴承套圈圆度测量，主要依靠两点式直径测量方法，该方法从原理上不符合圆度的定义，仅为一种近似测量方法，所以测量误差较大，且不能表征套圈的形貌误差。同时由于依赖手工操作测量，测量的可重复性较差，不稳定性较高。在轴承的试验检测，一般依靠圆度仪作为主要测量手段，但是该方法测量时间长，对操作人员要求高，无法实现对所有轴承的精确检测，只能按轴承批次进行抽检。同时，圆度仪的成本高，价格昂贵，对操作环境和条件的要求严格，通常仅限于计量室中使用，不适用于车间现场的大批量检测，无法与生产流水线对接。因此，亟需一种能够快速检测轴承套圈内、外径圆度的自动检测装置，并能够与轴承生产线无缝对接，从而实现轴承内外套圈圆度快速准确测量，提高整条生产流水线的效率。 At present, the roundness measurement of bearing rings on the production line mainly relies on the two-point diameter measurement method, which does not meet the definition of roundness in principle, and is only an approximate measurement method, so the measurement error is relatively large, and it cannot be characterized The shape error of the ferrule. At the same time, due to the dependence on manual measurement, the repeatability of the measurement is poor and the instability is high. In the test and detection of bearings, the roundness meter is generally used as the main measurement method. However, this method takes a long time to measure and requires high requirements for operators. It cannot realize accurate detection of all bearings, and can only conduct random inspections according to bearing batches. At the same time, the cost of the roundness meter is high, expensive, and has strict requirements on the operating environment and conditions. It is usually only used in the measurement room, and is not suitable for mass testing on the workshop site, and cannot be connected with the production line. Therefore, there is an urgent need for an automatic detection device that can quickly detect the roundness of the inner and outer diameters of the bearing rings, and can seamlessly connect with the bearing production line, so as to realize the rapid and accurate measurement of the roundness of the inner and outer rings of the bearing, and improve the efficiency of the entire production line. efficiency.
