摘  要
随着市场对产品质量要求的日益严格和国际上对环保要求力度的加强，我国精密零件清洗工业受到极大的挑战，长期在精密零件清洗领域占据主导地位的ODS类清洗工艺由于破坏臭氧层而被禁止使用，作为代替品出现的一些氯代烃清洗剂，水基清洗剂和碳氢溶剂由于分别具有毒性，水处理繁琐，清洗效果较差以及不易干燥，安全性较差等缺点。阻碍了国内清洗工业的发展。
本文主要对EG-6203型的轴承的生产中的清洗的工序的清洗设备的设计，它也是利用当今的科技超声波清洗代替了原来的机械清洗，工作过程如下：将要清洗的轴承放入自动上料机构的上料圆盘，上料圆盘在减速电机的带动下旋转，通过离心力的作用，轴承在挡料板的作用下，推料进入导归轨，再依次进入推料气缸的位置，在感应接触开关控制气缸在送料之前，上料台的导轨下有退磁器将轴承的磁性去掉，然后进入超声波清洗槽，然后是甩干槽，最后进入注脂包装生产线。本次设计的EG-6203型轴承超声波清洗机是PLC控制的全自动超声波清洗机。其具备了自动送料、自动感应退磁、自动记数、全程清洗喷淋风干、全程监控报警的功能。为现在的轴承制造业大大提高效率，使产品合格率大大提升。

 Abstract
With the market increasingly stringent requirements on product quality and the strengthening of the international requirements of environmental protection. Our precision parts cleaning industry is facing a great challenge. For the destruction of the ozone layer , the ODS class cleaning crafts are prohibited from using which has dominated for a long time in the field of precision parts cleaning. As a substitute for the emergence of some chlorinated hydrocarbon cleaning agents, Water-based cleaning agent and hydrocarbon solvents are toxic, water treatment is cumbersome. Besides, cleaning effect is less effective and hard to dry, what’s more, the security is low and other shortcomings. All those shortcomings have hindered the development of the domestic cleaning industry.
This paper focuses on the cleaning apparatus of the cleaning step in the production of the type EG-6203 bearing’s design. It uses current technology ultrasonic cleaning instead of the original mechanical cleaning, work processes are as follows: we take the bearing which has been cleaned  in the automatic feed mechanism feeding disc, The feeding disc were rotated by the gear motor. Through the effects of Centrifugal force, and bearing in the role of a blocking plate Pusher are   putted into the rail. And then turn into the pusher cylinder position. Sensor contact switch control cylinder before feeding back porcelain magnetic bearing is removed, and then into the ultrasonic cleaning tank, and then drying tank, and finally into the greasing packaging production line, feed station on the rail. The design of the EG-6203 bearing ultrasonic cleaning machine is PLC controlled automatic ultrasonic cleaning machine. With automatic feeding, auto-sensing demagnetization, automatic counting, the entire cleaning spray dried, monitor the entire alarm function. Now bearing manufacturing greatly improve efficiency, greatly enhance the rate of qualified products.

Key words: Ultrasonic wave；Bearing cleaning machine；Feeding mechanism；Automatic control.
