通过对汽车发动机曲轴某一段主轴颈的加工工艺研究,以及对曲轴加工刀盘工作原理的分析,提出了刀盘结构的设计要求,并对刀盘单元切削模块进行了分类,实现了刀盘结构的模块化设计。针对车梳拉刀盘模块中的刀夹-刀盘组合进行尺寸链的优化设计,刀盘的尺寸公差值从原来的12μm放宽到25μm,制造的经济性和合理性得到了提高。根据曲轴加工工艺要求,完成了车-车梳(拉)实验刀盘驱动装置的设计和切削力校核。曲轴加工实验刀盘已成功应用于车-车梳(拉)切削实验。

Based on the characteristics of the crankshaft machining process and the analysis of the cutting principle of the disk, the requirements of the disk structure was proposed, and the unit of the cutter module is classified to design the turn-turn chasing ( broaching) disk. Through the calculations of the cutting forces on rough machining condition, the stability of the turn-turn chasing ( broaching ) disk while cutting the crankshaft is verified. Based on the dimension chain theory, the assembly chain between the tool disk and the tool holder was optimized and redesigned. The related tolerance value of the cutting disk has been ampli-fied from 12 μm to 25 μm which improved the rationality and efficiency. According to the technological re-quirements of the crankshaft machining process,thedesign of the turn-turn chasing ( broaching) disk drive and the verification of the cutting force were carried out. The cutting disk has been succeed in the application of the experiment of the turn-turn chasing ( broaching) process.
