加工直齿离合器的传统工艺方法一般有两种:奇数齿是一次对刀加工而成;偶数齿却要分两次对刀才能加工出来。就是说工件要重新对一次刀才能铣出齿槽的另一侧。这里介绍一种一次对刀法加工偶数直齿离合器。笔者师徒在加工一批偶数直齿离合器时,开始分两次对刀加工,这种方法较麻烦,而且容易出差错。后来改进为一次对刀,具体方法如下:首先将刀子一侧对好中心,从外往中心进刀并且不要让刀子过工件中心, There are two kinds of traditional processing methods for machining straight-tooth clutches: Odd-numbered teeth are formed from one pair of knives; Even-numbered teeth need to be cut into two knives in order to be processed. This means that the workpiece must be re-paired once to cut the other side of the tooth gap. Here is a one-time knife method to deal with even-numbered straight-tooth clutch. When the mentor in the process of processing a group of even-numbered straight-tooth clutch, the beginning of two pairs of knife processing, this method is more troublesome, and prone to error. Later improved to a knife, the specific method is as follows: First, the knife on the right side of the center, from the outside to the center of the knife and do not let the knife over the workpiece center,
