3MZ1420是双头自动球轴承外沟磨床.pdf

摘 要 本文首先对 3MZ1310轴承内沟磨床进行了总体的概述，在对 3MZ1310轴承内沟磨床的加工工艺进行分析时，重点讲解了磨床的加 工工艺路线，砂轮成形及沟道磨削的方法，质量控制等一些问题， 其次将原磨床的规格，主要部件的结构和功能等也都一一讲述。在 磨头的设计与计算中本文主要对带，砂轮轴进行了受力分析以及各 方面的校核与保证质量。 砂轮在磨削时不可避免地将发生磨损，磨损后工件与砂轮的相 对位置发生变化，为保持工件与砂轮的相对位置不变，设计补偿机 构对3MZ1310轴承内沟磨床进行改进。随后本文又对夹具进行了设 计分析，其中对电磁无心夹具的结构等都做了介绍，使之达到要求。 关键词：沟道磨削 电磁无心夹具 磨头 1 Abstract In this paper, firstly, we summarized several aspects about the 3MZ1310 inner groove grinding system. When anslysing the machining technics of this system, emphases were attached to the machining route, the figuration of gringing wheels, grooving method and quality control. Furthermore, we introduced standards of the grinding system. Also the structure and function of each main components was presented respectively. Finally, in the design and analysis of grinding head, we mainly dealed with force analysis, examining and quality guarantee of belt and grinding wheel bearing. The grinding system was improved by adding a compensation mechanism. In all grinding process, the abrasion of grinding wheel is inevitable and this causes the relative position of gringding wheel to the workpiece changed. The compesation mechanism was developed for solving this problem. In succession, we designed and analysed the fixture. In this part, the structure and positioning errors of electromeganetic centreless fixture obtained particular introduce.
