铲齿车床用来加工铲齿背的铣刀和滚刀,这是大家熟知的。可是,根据我们的经验,利用铲齿车床的运动特点,还能加工一些用其它方法很难加工的零件。这种方法也适合于螺纹磨床。现将有关工艺介绍如下。一、加工压辊的扁身图1是带锯的锯路压辊。该压辊中间部分的扁身处要求并不高。但是加工却不省事,需铣扁,钳工手工锉,形状靠样板控制,热处理后再打光。后征得设计者同意,中间部分改为椭圆,如图2a所示。加工时我们在铲齿车床上装一个如图2b的偏心轮,就可以在铲齿车床上铲车和热处理后铲磨该零件了,加工起来很方便。铲齿车床的挂轮保证工件转一转,凸轮转两转。
It is well-known that shovel-type lathes are used to machine shovels and hobs. However, based on our experience, using the movement characteristics of a shovel lathe, it is also possible to machine parts that are otherwise difficult to machine. This method is also suitable for thread grinders. Now the process described below. First, the processing of flat roll pressure Figure 1 is a band saw saw pressure roller. The pressure roller in the middle part of the flat body at the request is not high. But the processing is not a problem, milling flat, fitter manual file, the shape of the model control, and then light after heat treatment. After the consent of the designer, the middle part is changed to ellipse, as shown in Figure 2a. Machining we have a scraper toothbrush as shown in Figure 2b Eccentric wheel, you can shovel in the shovel lathe and heat treatment shovel the parts, and processing is very convenient. Sprocket wheel to ensure that the workpiece turn a turn, turn the cam two.
