| 摘要：近几年数控成型磨削技术已经迅速发展成为一种新型的加工技术,其高效的精密方式在机械工程上有着极其广泛的应用。基于成形磨削技术所具有的极大和极广的应用前景 ，本论文介绍了成型磨削的特点和发展前景以及分析了砂轮在磨削中保持高精度的重要性，同时也说明了设计本课题的目的和意义。29303 本次设计采用金刚滚轮修整，这种结构的修整器修整效率高，能在很短的时间内完成砂轮的整形和修锐，且修整时修整力小、修具本省磨损小、修整精度高。金刚石滚轮砂轮修整器具有修整效率高、寿命长、便于冷却、结构简单、体积小、安装方便等优点。金刚滚轮在修整过程中的磨损较小，能够很好的减少在对砂轮进行修整时由于滚轮本身的磨损而引起的误差。整个装置采用了十字交叉滚柱导轨、波纹管弹性联轴器以及角接触球轴承等各种能够保证精度的装置。另外为了更好的提高装置的精度，设计中还使用了高精度光栅尺以及闭环控制。 毕业论文关键词：滚轮；磨损；高精度 Design of high precision diamond roller CNC dressing Abstract: In recent years, CNC forming grinding technology has rapidly developed into a new processing technology and its highly efficient manner precision mechanical engineering has an extremely wide range of applications .Based on form grinding technology with great and very broad application prospects, this paper describes the characteristics and development prospects shaped grinding wheel and the analysis of the importance of maintaining high precision in grinding, but also shows the design of this project the purpose and meaning. The design uses a diamond roller dresser, high dresser dressing efficiency of this structure, to complete the shaping of the wheel in a very short period of time and dressing and trimming the trimming force is small, with the province to repair wear small, high precision finishing. Diamond Wheel Dresser has a high dressing efficiency, long life, easy to cool, simple structure, small size, easy installation, and other advantages. Diamond wheel trimming process less wear, very good to reduce errors in grinding wheel dressing wheel itself due to wear caused.The entire device uses a cross-roller guides, the bellows flexible coupling and angular contact ball bearings and other means to ensure accuracy. Furthermore, in order to better improve the accuracy of the device, the design also uses a high-precision encoders and closed-loop control.
