Polishing motor pressing cylinder control device and system
The invention discloses a polishing motor pressing air cylinder control device and system which are used for controlling lifting or pressing operation of N pressing air cylinders, N is larger than or equal to 1, and the control device comprises N first branches and N second branches, the N first branches are uniquely connected to a rod cavity of one pressing air cylinder, and the N second branches are uniquely connected to a rodless cavity of one pressing air cylinder. The first branch comprises a first proportional pressure reducing valve, a first electromagnetic switch valve and a first flow amplifier which are sequentially connected in series, and the first proportional pressure reducing valve is connected to a rod cavity of the downward pressing air cylinder through the first electromagnetic switch valve and the first flow amplifier. The second branch comprises a second proportional pressure reducing valve, a second electromagnetic switch valve and a second flow amplifier which are sequentially connected in series, and the second proportional pressure reducing valve is connected to a rodless cavity of the pressing air cylinder through the second electromagnetic switch valve and the second flow amplifier. The technical problems that an existing downward pressing control device is high in cost, safety cannot be guaranteed, and downward pressing force output by an air cylinder cannot be accurately controlled can be solved.
本申请公开了一种打磨电机下压气缸控制装置及系统，用于控制N个下压气缸的提升或下压操作，N≥1，控制装置包括：N条唯一地连接至其中一个下压气缸的有杆腔的第一支路，及N条唯一地连接至其中一个下压气缸的无杆腔的第二支路。第一支路包括依次串联的第一比例减压阀、第一电磁开关阀及第一流量放大器，第一比例减压阀通过第一电磁开关阀、第一流量放大器连接至下压气缸的有杆腔。第二支路包括依次串联的第二比例减压阀、第二电磁开关阀及第二流量放大器，第二比例减压阀通过第二电磁开关阀、第二流量放大器连接至所述下压气缸的无杆腔。本申请能解决现有下压控制装置成本较高，安全性无法保证，气缸输出下压力无法精确控制的技术问题。
