| 摘 要： | 动力头是H钢三维数控钻孔机床的重要组成部件,本设计由于将动力头的主运动与进给运动高度集成.因此具有结构紧凑、重量轻、体积小,刚性好等特点,从而使H钢三维数控钻孔机床的结构简化,降低了制造成本.又由于动力头采用液压驱动,因此具有驱动力大、无级调速、可以在较大范围内进行孔的加工等优点.文章分别对外置液压缸式立式动力头和内置液压缸式卧式动力头的结构与工作原理作了介绍,并对卧式动力头的主运动、进给运动、控制系统以及机械结构特点等进行了分析.对动力头的主要参数和液压缸各部分参数的设计计算作了较详细的介绍.

| Abstract: | Hydraulic feed head is an important part of 3D NC drilling machine. Because of combination with main motion and feed motion, so not only it will be compact, light and rigid, but also it can reduce the cost, simplify structure, to achieve power and classless speed. In this paper, the working principles and basic structure of hydraulic feed head were introduced. Motional analysis, control system and feature of mechanical structure as well as main design calculation were detailed. |
