我厂在试制某项新产品的过程中,有一只与配套件相连接的齿轮,内孔是渐开线花键,尺寸和精度如图一。因一时无法解决花键拉刀或其它加工刀具,决定采用单齿成形法加工。在制造单齿插刀的过程中,刀具组陈志合师付根据齿轮齿条相啮合原理,改革了一套工具,在M6025C万能工具磨床上较好地解决了单齿插刀的磨削问题。经过磨削的插刀齿形见图2。 I plant in the trial of a new product in the process, there is a connection with the accessory gear, the hole is an involute spline, size and accuracy shown in Figure 1. For a moment can not solve the spline broach or other processing tools, decided to use single-tooth forming method. In the process of manufacturing single-tooth insert cutter, the cutter group Chen Zhihe pay according to the principle of gear rack engagement, the reform of a set of tools, M6025C universal tool grinder to better solve the single-tooth knife grinding problem. After grinding the knife tooth shape shown in Figure 2.
