为适应在车床上加工较长和斜度较小的外圆锥面,我们设计制造了一种专用顶尖(如右图),结构简单,使用方便。它由尾部体和顶尖体两部分构成。尾部体作成莫氏锥度插入尾座套筒内,尾部体与顶尖体连接处有燕尾槽,可使顶尖体水平移动,移动结束后可用螺钉2和5使两者锁紧固定。 设:顶尖 In order to adapt to machining longer and less tapered outer conical surface in lathe, we designed and manufactured a special top (pictured right), simple structure, easy to use. It consists of the tail body and the top body of two parts. The tail body is made into a Morse taper inserted into the tailstock sleeve. The dovetail groove at the connection between the tail body and the top body allows the top body to move horizontally. After the movement is completed, the two can be locked and fixed by the screws 2 and 5. Set: top
