安装轴装置、安装头、表面安装机
摘要：
安装轴装置(120)包括：花键轴(121)，贯通支撑部件(171)的轴孔(173)，在内部具有气压的供给通路；导入部件(161)，与阀(90)连通，将从所述阀(90)供给的气压向所述花键轴(121)的所述供给通路(131)导入；元件保持部(250)，位于所述花键轴(121)的轴端，通过所述花键轴(121)的所述供给通路(131)而接受所述气压的供给，来保持电子元件；花键螺母(151)，与所述花键轴(121)花键结合；及轴承部件(181)，在所述支撑部件的所述轴孔内，对所述花键轴以能够进行轴向上的直线动作与绕轴线的旋转动作这两种动作的状态进行轴支承，在所述花键轴的轴上，从所述元件保持部(250)起按照由近至远的顺序依次配置所述轴承部件、所述导入部件及所述花键螺母。
摘要（英）：

A mounting shaft device comprises a spline shaft including a supply passage for air pressure that extends through a shaft hole in a supporting member, an introducing member in communication with a valve and allowing the air pressure from the valve to be introduced to the supply passage, a component retainer disposed at an axial end of the spline shaft and configured to hold an electronic component by using the air pressure applied through the supply passage, a spline nut connected to the spline shaft through a spline mechanism, and a bearing supporting the spline shaft in the shaft hole in the supporting member both in a linearly movable manner in an axial direction and in a rotatable manner about an axis thereof. The bearing, the introducing member, and the spline nut are arranged on an axis of the spline shaft in this order from the component retainer.
