我们试制了一种镗铣气门座的简易设备,结构简单,体积小,一般社队修造站就可以自制,现简介如下。简易气门座镗铣机主要由手电钻、偏心磨盘,主轴、U形压杆、滑套、镗铣刀杆等组成(图1)。装在支架11上的于电钻,通过安装在手电钻锥孔里的主轴(上端为锥体,下端为花键轴),带动滑套旋转。滑 We trial a boring and milling valve seat of the simple equipment, simple structure, small size, the general community building station can be self-made, are briefings are as follows. Simple valve boring and milling machine mainly by the hand drill, eccentric disc, spindle, U-shaped bar, sliding sleeve, boring cutter bar and other components (Figure 1). The electric drill installed on the bracket 11 drives the sliding sleeve to rotate through the main shaft (the upper end is a cone and the lower end is a spline shaft) installed in the taper hole of the electric drill. slip
