偏心轴的钻Φ4夹具设计及机械加工工艺规程装备含4张CAD图+说明书

偏心轴

摘要
本次课程设计主要工作是设计偏心轴的加工工艺规程，特定工序的设计，以及偏心轴专用夹具的设计，以上工作的意义在于熟悉工件的加工过程，并给定该加工过程的方法、使用工具和加工顺序等，通过实际操作，熟悉零件加工过程，并锻炼拥有自主设计的能力，同时也对特定工序进行设计，能够加强对工序的了解和掌握基本设计工序的能力，之后就是偏心轴夹具的设计，设计时需要掌握六点定位原理，首先对偏心轴进行定位，在保证了六个自由度被限制之后要进行加紧装置的设计以及夹紧力的计算，夹具体的设计等等，通过以上过程，可以加深对六点定位原理的认识，以及其他细节性的东西的全方面的了解。
Abstract
The main work of this course design is to design the process procedure of eccentric shaft, the design of specific processes, and the design of special fixtures for eccentric shaft. The significance of the above work is to be familiar with the processing process of the workpiece. And given the method of the processing process, the use of tools and the processing order, etc., through the actual operation, familiar with the parts processing process, and exercise the ability to have independent design, but also to design specific processes, Can strengthen the understanding of the process and master the ability of the basic design process, followed by the design of the eccentric shaft fixture, the design needs to master the six-point positioning principle, first of all the eccentric axis positioning. After ensuring that the six degrees of freedom are limited, the design of the tightening device and the calculation of the clamping force, the specific design, etc., can be carried out. Through the above process, the understanding of the six-point positioning principle and other details can be deepened.
