Liquid level control system of five-axis machining center spindle box

Abstract

A liquid level control system of a five-axis machining center spindle box comprises an oil liquid conveying device, the spindle box, an oil liquid recycling device and a liquid level electrical control program unit. The liquid level control system is characterized in that the oil liquid conveying device is provided with a liquid level alarming and flow monitoring electrical part and communicates with the liquid level electrical control unit; a communicating four-cavity structure is formed in the lower portion of the spindle box, and oil outlets in the two positions are located in the opposite angle positions of the front end of the spindle box correspondingly; a duplex gear pump is adopted in the oil liquid recycling device, pump oil extraction ports are connected with the oil outlets in the opposite angle positions of the spindle box through oil pipes, the control amount of the oil tank volume is the sum of the maximum dynamic oil liquid volume of an inner cavity of the spindle box and the pipeline volume, the liquid level electrical control program unit is input, automatic control is executed through a liquid level switch, the height of oil liquid in the spindle box is kept to be smaller than the height of the spindle connecting position during swinging, and the oil liquid is prevented from entering a spindle. Oil liquid recycling is good, the mechanical spindle is adopted, the rotation speed is increased to 4,000 r / min, and the machine tool efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a liquid level control system of a spindle box of a gantry / vertical five-axis machining center. Background technique [0002] The five-axis machining center can realize five-axis linkage to complete the processing of various complex plane and curved surface parts. During the machining process, the AB axis is constantly changing, and the swing range is large, and the liquid level in the spindle box is constantly changing with the swing of the AB axis. The liquid level refers to the height of the lubricating cooling oil entering the spindle box and accumulating liquid level due to the inability to completely flow out due to the angle of the oil return port under dynamic conditions. The ideal state is that the lubricating oil in the headstock flows against the wall without accumulation. If the liquid level in the spindle box cannot be effectively controlled, resulting in exce...
