气动式内园自动分类机

本机可将精纺机锭子滚柱轴承的外环的内经分为10类,每类公差为0.002毫米。全机分为三个部分:1.差动式气动量仪部分;2.自动机构部分;3.电气部分。本机的特点系采用压缩空气进行测量。气动量仪采取差动式,对进气压力的变化不敏感,因而提高了分类的精度。气动塞规的气路采取十字形,可以测量出内孔的平均直径。本机的生产率为300件/小时.     

A METHOD OF ANALYSIS OF MACHINE TOOL TRANSMISSION CHAIN ERROR

The indexing transmission chain error of gear cutting machines is an obviously periodic timefunction. If data are acquired properly while surveying and analyzing the error with grating typeinstrument attached to a micro-computer, the analysis will be easier and quicker. In this paper,such a system is introduced; a data acquiring interface is designed. Therefore, real-time samplingcan be performed. The results obtained from the indexing tramsmission chain error of several gearhobbing and shaping machines with this system were satisfactory.     

錠胆壳双孔同心度檢驗方法的探討

錠胆壳为精紡机上一个重要零件,其上有二个內孔規定其同心度<0.025毫米。由于錠胆壳的结構特殊,其双孔同心度的检验問题庄工厂中多年来末获得正确的解决。本文中分析了这个问题中的主要困难,同时对于运用气动測量方法来解决这个問題的可能性作了理論上的分析。
