在加工一些精密孔的生产实践中,常常需要进行光整加工。例如:在一次安装下进行抛光或用滚压进行表面强化。为此,制成半自动光整加工镗床用主轴头,这种主轴头装在2706型机床的桥形支承垫板上。根据生产的需要,最多可装六个主轴头。图1为主轴头的传动系统。它是由与可调节的偏心轮2相连的花盘1、传动轴3、齿轮4、丝杠5、横架6、齿轮轴8、行星机构9、皮带轮10、电机11、高速电轴12、软轴13
In the production of some precision hole production practice, often need finishing. For example: Polishing in one installation or surface hardening with rolling. To this end, made of semi-automatic finishing machine head with boring head, headstock mounted on the 2706-type bridge on the bearing plate. According to production needs, can hold up to six spindle head. Figure 1 for the spindle head drive system. The utility model is composed of a faceplate 1, a transmission shaft 3, a gear 4, a screw shaft 5, a horizontal frame 6, a gear shaft 8, a planetary gear 9, a pulley 10, a motor 11, a high speed electric shaft 12, a soft Shaft 13
