工程陶瓷珩磨加工珩磨头的设计
摘要
本设计是对加工工程陶瓷材料的珩磨头的结构设计,我首先通过查阅有关的视频，了解了珩磨加工的特点，再查阅相关资料认识了解珩磨机的工作原理，清楚其结构组成，然后重点观察现有珩磨头的结构，对我国的珩磨机掌握其运动参数的选择原则、油石个数的选择油石的形状和密度及分布原理、涨锥的设计技术要求以及进给机构的运动装置等；然后通过和老师不断的沟通与交流，确定了设计方向。最后分析了现有珩磨头结构的缺点，确定了对工程陶瓷加工所用珩磨头的总体方案。
在确认方案后通过对珩磨头结构的设计对各个具体零件进行相应的设计，然后对一些有强度要求和扭矩要求的零件进行校核，使设计出的结构确保磨削可靠运行，最后绘制整套的珩磨头结构的装配图和零件图。
在通过对珩磨头的结构设计，使书本知识和理论与实际生产相结合，加强了对机械设计，工程材料，理论力学，机械原理等相关专业知识的理解，让自己能运用书本知识设计出基本符合生产要求的零部件。而且在论文中我充分地运用了大学期间所学到的知识进行了复习，巩固和深化，达到了预期的设计意图。

The design of the honing machining engineering ceramics honing head
Abstract
This design is the structure of the honing head of machining engineering ceramics material design, I first by looking at the video, understanding of the features of the honing process, and then understand the working principle of honing machine to consult the relevant information, know its structure, and then focus on observation of the structure of existing honing head, to our country of honing machine to master the principle of choosing the motion parameters, the number of the choice of sharpening stone shape and density, and distribution principle, design and technical requirements as well as the rise of cone motion device of can feed mechanism, etc: Then through constant communication and communication and the teacher, determine the design direction. In the final analysis the shortcoming of the existing structure of honing head, used for machining engineering ceramics was determined the overall scheme of the honing head.
After confirm scheme using the set of honing head structure design principle to each specific parts of the corresponding design, and then some, the strength and torque requirements of parts of the structure of the designed to ensure reliable operation of grinding, finally draw a complete set of the honing head structure of the assembly drawing and part drawing.
In through the structure of honing head design, make the book knowledge and theory combined with the actual production, strengthens the of mechanical design, engineering material, theoretical mechanics, mechanical principle and so on the understanding of the relevant professional knowledge, let oneself can apply book knowledge to design basic meet the requirements of the production parts. And in the thesis I fully apply the knowledge learned during the period of university has carried on the review, consolidate and deepen, achieved the desired design intent.
Key words: oil stone; Cone up; Honing head.
