1965年第7期“机械工人”刊物曾刊登了广州机床厂关于“高速车螺纹自动退刀装置”一文,对我们很有启发。但他们所介绍的装置只实现了自动退刀,不能自动还原到进刀位置。我们在学习广州机床厂经验的基础上,设计制造了结构简单的“高速车螺纹自动退刀还原装置。”这种装置除能使刀具在切完整个螺纹长度后,实现自动快速退刀外,还能使刀具在返程(主轴反转)到切螺纹开始位置时,自动地使刀具推进到头一次走刀时的位置(简称还原)。此装置适合于高速
1965 No. 7 “mechanic ” publication has published in Guangzhou Machine Tool Plant on the “high-speed car thread automatic retractor ” article, very enlightening for us. However, the device they introduced only achieved automatic retraction, can not be automatically restored to the feed position. We learn from the experience of Guangzhou Machine Tool Plant, based on the design and manufacture of a simple structure “high-speed car thread automatic retractable reduction device. ” This device can not only enable the tool to cut the entire thread length, automatic rapid retraction In addition, the tool can also make the tool advance to the position when the first pass (return reduction) automatically when returning (spindle reversing) to the starting position of thread cutting. This device is suitable for high speed
