去年以来,我们模拟射流控制原理,在轴承套圈精车内孔、倒角、车沟槽三道工序中,采用了气动控制。设计改装了十一台半自动机床,经过一年多的使用实践,效果颇好,可降低劳动强度,提高单机产量,且质量稳定,达到了简单、易行和节约的目的。 气动控制主要由三大部分组成,即发讯装置,转换装置和工作装置。 Since last year, we have simulated the principle of jet control and adopted pneumatic control in the three processes of the inner bore, chamfer and car groove in the bearing ring fine car. Design and modification of eleven semi-automatic machine tools, after more than a year of practice, the effect is quite good, can reduce labor intensity and improve stand-alone production, and the quality of stability, reached a simple, easy and save the purpose. Pneumatic control is mainly composed of three parts, namely, sending device, converting device and working device.
