在立车上车削如图1所示盘类零件的锥面,采用扳动垂直刀架角度的方法是无法加工的。工艺科王瑜同志为我车间设计了一套挂轮架,装在C523立车垂直四方刀架进给箱的手动轴端,使垂直四方刀架在水平方向和垂直方向按一定比例进给,实现大锥角锥面的车削,效果良好,现介绍如下。一、进给运动的合成假如刀尖在维面上的进给速度为S,由图2可知,它在水平方向的进给速度S_x和在垂直方向的进给速度S_v分别为: S_x=S·sina S_v=S·cosa两式相除整理得: S_x=tga·S_v (1) 从(1)式知,只要垂直四方刀架横进给速度和垂直进给速度按比值tga(锥面斜度值)进行搭配,那末
In the vertical turning on the car shown in Figure 1 disc cone parts, with a vertical angle to pull the knife method is unable to process. Technology Branch Wang Yu comrades for my workshop designed a set of wheel carrier, installed in the vertical axis C515 vertical carriages feed box manual shaft end, so that the vertical square turret in the horizontal and vertical direction by a certain percentage of feed, To achieve a large cone angle taper turning, the effect is good, are presented below. First, the synthesis of feed motion If the tip in the dimensional plane of the feed rate of S, from Figure 2 we can see that it in the horizontal direction of the feed speed S_x and vertical feed speed S_v were: S_x = S · Sina S_v = S · cosa Two types are divided: S_x = tga · S_v (1) From equation (1), as long as the vertical square turret feed speed and vertical feed rate according to the ratio of tga Degree value) with the match, then
