图示为直轴式柱塞泵(马达)小规格柱塞在车床上用三滚轮辗压收口组合的示意图。滑履夹头夹持在车头上,收口器安装在车床尾座上。使用时,滑覆放置在弹簧夹头内,柱塞体放置在收口器内,通过弹性顶尖将柱塞体顶在滑履上,转动螺母夹紧滑履。工作时,主轴旋转,转动螺旋套,三滑块沿阿基米德螺旋线下降,带动滚轮向中心运动,作用于滑履裙部,边滚边挤,使滑展裙部沿柱塞体球面流动,达到包容(组合)的目的。经试验组合,记取主轴转速和螺旋套进给参数,便可进行批量加工。
The schematic diagram shows the combination of a small-size plunger of a direct-axis piston pump (motor) on a lathe with a three-roller rolling port. Traction chuck clamped in the front of the car, shuttlecock installed on the lathe tailstock. When in use, the slippage is placed in the collet, the plunger body is placed in the retractor, the plunger body is placed on the shoe by the elastic tip, and the nut is tightened to grip the shoe. Work, the spindle rotation, turning the spiral sleeve, the three slide along the Archimedes spiral down, driving the wheel to the center of the role of the skate skirt, squeezing the edge of the roller so that the skating skirt along the plunger body of the spherical flow , To achieve inclusive (combination) purposes. After the test combination, take the spindle speed and screw feed parameters, can be batch processing.
