苏联明斯克拉床专业设计局设计了在主轴高速运转与钻深孔时保证工具冷却的装置。装置的壳体5用带螺纹的法兰盘6和管接头7刚性地固定于机床的顶针套筒上。主轴4上紧固具有四个叶片的导流叶轮11作为能量增强器,其圆周部份呈阿几米德螺旋线型。在主轴上安装工具2供零件1钻孔。润滑冷却液从机床的电动泵注入装置的管接头,并在压力作用下进入环形室9。当主轴启动时,导流叶轮转动,同时冷却液进入倾斜通道10,而后经通道8流入垂直通道3。通道10、8和3从一端通往另一端形成螺旋通道,该螺旋通道把螺旋涡流运动传给润滑冷却液流,从而在垂直通道3内形成高压区,这样便
The Minsk Claw Bed Design Bureau of the Soviet Union designed a device that ensures tool cooling when the spindle is running at high speed and drilling deep holes. The housing 5 of the device is rigidly secured to the thimble sleeve of the machine tool by means of a threaded flange 6 and a nipple 7. As the energy booster, the guide vane 11 with four vanes is fastened on the main shaft 4, and the circumferential portion thereof is in the form of an Archimedes helix. Install tool 2 on the spindle for part 1 drilling. Lubricating coolant is injected from the machine’s motor-driven pump into the pipe fitting of the device and enters the annular chamber 9 under pressure. When the spindle is started, the guide vane rotates, while the coolant enters the inclined channel 10 and then flows into the vertical channel 3 via the channel 8. Channels 10, 8 and 3 pass from one end to the other forming a helical passage that transmits the helical vortex motion to the flow of lubricating coolant to create a high pressure zone within the vertical passage 3 so that
