    • PROBLEM TO BE SOLVED: To provide a machine tool, surely supporting a tool to be held on both sides without any influence of a change in work diameter and abrasion of a tool. SOLUTION: A tool support unit 20 is composed of a movable part 21 having a support member 22 for rotatably supporting the other end of a hob H, one end of which is mounted on the spindle head 9, through an arbor A and a fixed part 35 fixedly set on a turret 14 to slidably support the movable part 21. The movable part 21 includes: a first holding member 24 rotatably holding the support member 22; second holding members 25a, 25b holding the first holding member 24 to rotate around the axis orthogonal to the rotating shaft of the support member 22; and a slide member 27 fitted to a slide guide connected to the second holding members 25a, 25b and formed on the fixed part 35. When the tool support unit 20 is indexed to a tool support position, the movable part 21 is moved forward and backward in the Y-axis direction. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了提供一种机床,确保将工具保持在两侧,而不会影响工件直径和工具磨损的变化。 解决方案:工具支撑单元20由具有支撑构件22的可移动部分21组成,支撑构件22用于可旋转地支撑滚刀H的另一端,其一端通过心轴A安装在主轴头9上, 固定部35固定地设置在转台14上以可滑动地支撑可动部21.可动部21包括:可旋转地保持支撑部件22的第一保持部件24; 保持第一保持构件24围绕与支撑构件22的旋转轴正交的轴线旋转的第二保持构件25a,25b; 以及滑动构件27,该滑动构件27安装到与第二保持构件25a,25b连接并形成在固定部35上的滑动引导件。当工具支撑单元20被转位到工具支撑位置时,可动部21向前和向后移动 在Y轴方向。 版权所有(C)2005,JPO&NCIPI
