    • PROBLEM TO BE SOLVED: To provide: a rotary table device that can prevent loosening of a positioning screw for stopping a rotary table at a predetermined indexing position; and a machine tool.SOLUTION: Pitch of a screw thread of a second male screw portion 103 of a first positioning screw 100 is smaller than pitch of a screw thread of a first male screw portion 102. That is, the pitch of the screw thread of the first male screw portion 102 is larger than pitch of the screw thread of the second male screw portion 103. Therefore, when the first male screw portion 102 rotates as much as the second male screw portion 103 rotates, the first male screw portion 102 moves toward a rear end portion 106 more than the second male screw portion 103. This can cause tension A to act on between an end portion 105 and a rear end portion 106 of a shaft portion 101 of the first positioning screw 100, preventing the first positioning screw 100 from loosing.
    • 要解决的问题:提供一种旋转台装置,其能够防止在预定的分度位置使旋转台停止的定位螺丝的松动; 和机床。解决方案:第一定位螺钉100的第二外螺纹部分103的螺纹的间距小于第一外螺纹部分102的螺纹的间距。也就是说,螺纹的螺距 第一阳螺纹部102的旋转大于第二阳螺纹部103的螺纹的间距。因此,当第一阳螺纹部102与第二阳螺纹部103旋转一样多时,第一阳螺纹部102 比第二外螺纹部分103向后端部106移动。这可能导致张力A作用在第一定位螺钉100的轴部101的端部105和后端部106之间,从而防止第一 定位螺钉100松动。

    • PROBLEM TO BE SOLVED: To provide a machine tool having a small number of parts and capable of finely adjusting the position of a tool attached to a turret member.SOLUTION: A machine tool has a direct drive in which a rotor 48b of a built-in motor 48 is directly attached to a rotation shaft section 46b of the turret member 46. In addition, when a desired tool T is determined from a plurality of tools T attached to the turret member 46 and a workpiece W is processed, the machine tool drives a hydraulic mechanism 54 and clamps a brake disk 51 with a brake pad 52, thereby fixing the turret member 46 to be unrotatable to a housing 42 by frictional force.
    • 要解决的问题:提供一种具有少量部件并能够精细调节附接到转台构件的工具的位置的机床。 解决方案:机床具有直接驱动,其中内置马达48的转子48b直接附接到转塔构件46的旋转轴部分46b。另外,当所需的工具T由 处理附接到转塔构件46和工件W的多个工具T,机床驱动液压机构54并用制动衬块52夹紧制动盘51,从而将转塔构件46固定成不可旋转的壳体 42由摩擦力。 版权所有(C)2012,JPO&INPIT
