【摘要】：為實(shí)現(xiàn)活塞橢圓銷(xiāo)孔加工的新方法,需要主軸軸心沿著期望的小橢圓軌跡運(yùn)動(dòng)。對(duì)一種液壓伺服回路系統(tǒng)進(jìn)行深入研究,利用回路中的電液伺服閥來(lái)主動(dòng)控制軸心的運(yùn)動(dòng)軌跡。首先建立主軸的動(dòng)力學(xué)方程,并聯(lián)立雷諾方程、流量連續(xù)性方程及承載力公式,獲得了軸心運(yùn)動(dòng)坐標(biāo)與電液伺服閥控制參數(shù)的定量關(guān)系。最后利用MATLAB軟件得到軸心運(yùn)動(dòng)軌跡為橢圓時(shí),伺服閥的控制參數(shù)及靜壓油腔的壓力參數(shù),這為活塞橢圓銷(xiāo)孔精密加工新方法的后續(xù)實(shí)現(xiàn)奠定了理論基礎(chǔ)。
[Abstract]:In order to realize the new machining method of piston elliptic pin hole, it is necessary for the spindle axis to move along the desired small elliptical trajectory. A kind of hydraulic servo loop system is deeply studied. The electro-hydraulic servo valve in the loop is used to actively control the motion trajectory of the axis. Firstly, the dynamic equations of the spindle, the parallel vertical Reynolds equation, the flow continuity equation and the bearing capacity formula are established. The quantitative relationship between the axis motion coordinate and the control parameters of the electro-hydraulic servo valve is obtained. Finally, the control parameters of the servo valve and the pressure parameters of the hydrostatic oil chamber are obtained by using MATLAB software when the axis motion track is elliptical. This lays a theoretical foundation for the following realization of the new precision machining method for piston elliptical pin holes.
