一种精密控制油缸
摘要：
本实用新型公开了一种精密控制油缸，主要包括控制器、位移传感器、脉冲油缸、单向阀、电磁阀a、脉冲泵、电磁阀b、受控油缸，其特征在于：脉冲油缸的活塞杆伸出端与位移传感器相连接，控制器与位传感器、脉冲泵、电磁阀a、电磁阀b控制连接；脉冲泵通过电磁阀a和单向阀与脉冲油缸连接，脉冲油缸的出油口通过电磁阀b与受控油缸连接。本实用新型通过位移传感器检测脉冲油缸的活塞杆位移量，通过控制器反馈控制脉冲泵，以精确控制脉冲油缸的油液输出量，进而提高受控油缸的位移精度，本实用新型所述的一种精密控制油缸结构简单，行程控制精度可达到亚微米级。
摘要（英）：

The utility model discloses a fine control hydro -cylinder mainly includes controller, displacement sensor, pulse hydro -cylinder, check valve, solenoid valve a, pulse pump, solenoid valve b, controlled hydro -cylinder, its characterized in that: the piston rod of pulse hydro -cylinder stretches out the end and is connected with displacement sensor, controller and position sensor, pulse pump, solenoid valve a, solenoid valve b control connection, the pulse pump passes through solenoid valve an and the check valve is connected with the pulse hydro -cylinder, and the oil -out of pulse hydro -cylinder passes through solenoid valve b and is connected with controlled hydro -cylinder. The utility model discloses a displacement sensor detects the piston rod displacement volume of pulse hydro -cylinder, through controller feedback control pulse pump to the fluid output quantity of accurate control impuls hydro -cylinder, and then improve the displacement precision of controlled hydro -cylinder, a fine control hydro -cylinder simple structure, stroke control accuracy can reach submicron.
