本文介绍了一种使镗杆产生弹性弯曲变形来消除镗孔退刀划痕的让刀机构。此机构由液压系统实现动作,工作可靠,生产效率高。文中简要地介绍了机构的工作原理和镗杆变形量的设计计算方法。
This paper introduces a let boring bar elastic bending deformation to eliminate boring retractable knife letting knife mechanism. This mechanism by the hydraulic system to achieve action, reliable, high production efficiency. The paper briefly introduces the working principle of the mechanism and the design calculation method of boring bar deformation.
