The invention provides a micro-feeding control device, method and system for a double-wheel slot milling machine. The double-wheel slot milling machine comprises a slot milling winch and a speed reducer connected with the slot milling winch, the system low-speed feeding motor is connected with the low-speed feeding end of the speed reducer; the auxiliary valve is connected with the low-speed feeding motor through a feeding oil way and a lifting oil way respectively; and the rectifying valve group is arranged on the lifting oil way and is used for regulating and controlling the bidirectional speed in the feeding and lifting processes. The rectification assembly is arranged on the lifting oil way, so that in the micro-feeding control process of the double-wheel slot milling machine, bidirectional speed regulation and control in the feeding and lifting process can be achieved through the rectification assembly, a control dead zone caused by internal leakage of a motor is eliminated, and the control precision of micro-feeding is improved.
本发明提供一种双轮铣槽机的微量进给控制装置、方法及系统，双轮铣槽机包括：铣槽卷扬，以及与所述铣槽卷扬连接的减速机；系统低速进给马达，与减速机的低速进给端连接；辅阀，与低速进给马达分别通过进给油路和上提油路连接；整流阀组，设置于上提油路，用于实现进给和上提过程中双向速度的调控。本发明通过在上提油路上设置整流组件，使得双轮铣槽机在微量进给控制过程中，能够通过整流组件实现进给和上提过程中双向速度的调控，消除了马达内泄带来的控制死区，提高了微量进给的控制精度。
