The invention belongs to the technical field of mechanical operation, and particularly discloses a hydrostatic pressure guide rail oil supply device. The hydrostatic pressure guide rail oil supply device comprises a device frame body, a driving mechanism, an oil distribution component, an oil pressure adjusting mechanism and an oil temperature adjusting mechanism; the driving mechanism, the oil distribution component and the oil pressure adjusting mechanism are all mounted on the device frame body; the driving mechanism is connected with an external oil supply tank and communicates with an external hydrostatic pressure guide rail through the oil distributing component; and the oil pressure adjusting mechanism monitors and adjusts the oil pressure of the driving mechanism; the oil temperature adjusting mechanism monitors and adjusts the oil temperature of the driving mechanism; during use, the oil pressure adjusting mechanism can calculate a reasonable voltage and current and power of the driving mechanism according to a difference value between a preset pressure value and a sampled real-time pressure value, so that the voltage and current and the power of the driving mechanism reach preset values; and the oil supply pressure can be flexibly and conveniently adjusted according to a load, and meanwhile, the oil supply temperature is basically constant, so that the operation requirement of the hydrostatic pressure guide rail is accurately guaranteed, the operation rigidity and linearity of the guide rail are improved, and the energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of mechanical operation, and more specifically relates to an oil supply device for an ultra-precision hydrostatic guide rail. Background technique [0002] At present, with the development of ultra-precision manufacturing and the demand for difficult-to-machine materials, there are more and more applications of ultra-precision hydrostatic guide rails with high rigidity characteristics. The stability of the output oil pressure and oil temperature of the hydrostatic guide rail oil supply device directly It affects its running accuracy and positioning accuracy. The existing products basically use the pressure control valve to control the oil supply pressure, not only the energy loss is large, there is a large pressure fluctuation, but also the oil temperature rises, which seriously affects the oil viscosity and the control accuracy of the hydrostatic guide rail. . [0003] Therefore, how to provide an oil del...
