摘要

本文介绍了自动车床的工艺系统,特别是凸轮卡盘对生产条件下轴承套圈加工精度的影响。研究了单列圆锥滚子轴承32017X外径环的非圆度在加工过程中的变形值。在研究中,选择的样品是在不干扰工艺过程的情况下,直接在PJSC“SKF乌克兰”生产单元在相同条件下加工的。提出在卡盘设计中采用可更换式浮动凸轮,以提高加工精度和生产率。实验研究表明,被加工表面的椭圆度取决于卡盘凸轮的夹紧力。说明了统计数据的计算机处理对工程产品精度控制的有效性。介绍了利用Minitab计算机程序在生产中实现加工精度控制的方法。事实证明,产品的质量是在零件制造和控制的各个阶段使用现代计算机技术的影响下形成的,这确保了在大范围内技术参数变化的研究,并将个别研究与机器的实际加工条件进行比较,其结果具有足够的可靠性。

Impact of Technological System’s Characteristics on the Machining Accuracy of Bearing Rings
The article shows the influence of the technological system of an automated lathe, in particular cam chucks, on the accuracy of machining bearing rings for production conditions. The value of the deformation during machining, i.e., the non-circularity of the ring of a single row tapered roller bearing 32017X in outer diameter, was investigated. For the study, samples were selected that were processed under the same conditions directly in the production unit of PJSC “SKF Ukraine” without interference with the technological process. The use of replaceable floating cams in the chuck design was proposed to increase the accuracy and productivity of machining. Experimental studies have shown that the machined surface’s ovality depends on the chuck cams’ clamping force. The effectiveness of computer processing of statistical data on the accuracy control of engineering products was shown. Implementing machining accuracy control in production using the Minitab computer program was presented. It was proven that the quality of products is formed under the influence of the use of modern computer technologies at all stages of manufacturing and control of parts, which ensures research in a wide range of changes in technological parameters and comparison of individual studies with actual machining conditions on the machine, with the results of a sufficient level of reliability.
