利用磨削火花辅助测评产品加工质量
发布时间：2018-10-21 08:20
【摘要】：轴承圆锥滚子的外径磨削加工是在无心磨床上进行的,其加工模式属大批量连续作业。通常状况下,其加工过程的质量控制是采用仪器仪表抽样检查的方法来测量被磨削工件,质量抽检贯穿于整个加工流程,如果正常时的产品可以达到免选标准,即在每个单元接料装盘中的滚子相互差符合轴承配套装配公差的工艺要求。但随着机床加工条件的动态变化和砂轮的消耗,即使利用新式自动补偿技术的机床也未必能满足加工不断变化而质量要求能够稳定的条件,稍有疏忽不合格产品就会批量出现,这时假若具备磨削火花产生和变化判断的基本常识,对于产品质量的测评和控制以及防止混料是大有帮助的。凭借观察磨削火花变化规律,直观正在磨削运行中的滚子质量概况,适时调整无心磨床的各相关辅助工装从而达到及时控制产品质量的目的,这是一种全新的思路,观点也只是一种尝试,正确与否值得商榷。
[Abstract]:The outside diameter grinding of bearing cone roller is carried out on the centerless grinding machine. In general, the quality control of the machining process is to measure the grinding workpiece by means of instrumentation sampling inspection, and the quality sampling inspection runs through the whole process, if the normal product can reach the non-selection standard, In other words, the roller difference in each unit meets the requirements of bearing assembly tolerance. However, with the dynamic change of machine tool processing conditions and the consumption of grinding wheels, even the machine tools using the new automatic compensation technology may not be able to meet the changing conditions of machining and the quality requirements can be stable, and any neglect of unqualified products will appear in batches. At this time, if we have the basic knowledge of the generation and change judgment of grinding sparks, it will be of great help to evaluate and control the quality of products and prevent mixing. By observing the changing law of grinding spark, we can visualize the general situation of roller quality in grinding operation, and adjust the relevant auxiliary tools of centerless grinder in time to control the quality of products in time. This is a new way of thinking. The point of view is only an attempt, and whether it is correct or not is open to question.
