摘要
曲轴是传动设备,特别是汽车上主要的轴类零件,其质量的好坏直接影响传动性能的强弱,其加工过程任何一道工序都不可掉以轻心,用于曲轴锻造毛边磨削的专业磨床,是曲轴生产中必不可少的重要设备之一。
本毕设课题,在对现有曲轴磨削设备充分了解的基础之上,阅读了大量文献资料,运用大学四年所学的机械设计、机械加工、机械电子等多专业知识,从整体上对设备进行宏观设计,细节上微观调整,尽量使设计出来的设备是切实可用的。在设计过程中,充分考虑到机械加工的难度和可信性,充分考虑标准件和外购件的选用,尽量减少自加工的零件,这样可大大增加设备的灵活性和组装难度。同时,考虑到操作人员的操作感受,降低操作人员的劳动强度,增加其操作安全性,相信这样一款设备必定具有一定的实践意义。
首先,基于现有的曲轴磨床结构,提出了升级版的整体结构设计和自动化实现方式。
其次,基于整体结构设计方案,集合所学知识和文献资料,将整台设备分解成若干功能组件,对各个组件进行细节化实现设计。
最后,在三维软件SolidWorks 2013里建模,模拟设备的整体组装效果和检验所做设计。

Summary
The crankshaft is the transmission equipment, especially the main axle parts in the car. The quality of the crankshaft directly influences the transmission performance. It can't be taken lightly in any process of the machining process. The professional grinding machine for crankshaft forging and flashing is One of the most important equipments in crankshaft production.
This completed project, based on a thorough understanding of the existing crankshaft grinding equipment, read a large amount of literature and materials, and used the multi-disciplinary knowledge of mechanical design, mechanical processing, and mechanical electronics learned by the university for four years. The equipment is designed in a macro-scale and the details are fine-tuned to make the designed equipment as practical and usable as possible. In the design process, full consideration is given to the difficulty and credibility of the machining process. Full consideration will be given to the selection of standard parts and purchased parts to minimize self-manufactured parts. This will greatly increase equipment flexibility and ease of assembly. At the same time, taking into account the operator's operating experience, reduce the labor intensity of the operator, increase its operational safety, I believe that such a device must have a certain practical significance.
First, based on the existing crankshaft grinding machine structure, an upgraded version of the overall structural design and automation is proposed.
Secondly, based on the overall structure design scheme, the collected knowledge and literature materials are collected, the entire equipment is decomposed into several functional components, and the detailed design of each component is implemented.
Finally, modeling in 3D software SolidWorks 2013 simulated the overall assembly effect of the device and verified the design.

课题背景和研究意义
课题背景
曲轴是好多行业应用非常广泛的零件,其作用是将直线运动和转动做相互转换。例如发动机、冲压机、剪板机等行业机械,均使用到曲轴零件。曲轴的特点就是结构复杂,工作条件恶劣,受力情况多变,因此,对曲轴零件提出了更高的加工精度和力学性能要求。
近年来,随着制造业的再度发展,相关科学技术的进步,各行各业对制造业提出了更高的要求。其中磨削技术就是高精度制造中必不可少的关键工序。磨削技术的高低,直接影响产品最终的质量。
现今,磨削加工技术向着高速度、高精度、高效率方向发展,自动化程度也是衡量标准之一。但是,采用传统磨削技术的磨床仍然占据着很大一部分加工份额。所以,对传统磨床的结构设计仍然具有现实意义。在整个机械加工领域,磨削加工占据着加工足量的30%~40%,相应的磨削设备种类繁多,结构各异,满足了不同行业、不同零件的加工要求。
