为了改善键槽铣刀的工作条件,增加铣刀的刚性,延长刀具的使用寿命,我们设计了键槽铣刀通用刚性支承,使用效果很好。安装时,锥度套筒10安装在支架内,并由悬梁把支架固定在确定的位置上,两头用二个圆螺母调整距离后拼紧,其内孔与顶尖轴的套筒3做成间隙配合。径向球轴承12、推力轴承13连同顶尖轴1一起安装在套筒3内,保证了铣刀工作时的同轴度和减轻摩
In order to improve the working conditions of the key groove milling cutter, increasing the rigidity of the cutter and prolonging the service life of the cutter, we designed the universal rigid support of the key groove milling cutter, and the effect is very good. During installation, the taper sleeve 10 is installed in the bracket, and the bracket is fixed in a certain position by the suspending beam. The two ends are fastened with two round nuts to adjust the distance, and the inner hole is in clearance fit with the sleeve 3 of the top shaft . Radial ball bearings 12, thrust bearings 13 along with the top shaft 1 installed in the sleeve 3 to ensure that the work of the milling cutter coaxiality and reduce friction
