夹具装配图
摘要
气门摇杆轴支座是柴油机一个主要零件,是柴油机摇杆座的结合部。本文主要论述了气门摇杆轴支座的加工工艺及其夹具设计。气门摇杆轴支座的尺寸精度、形状精度以及位置精度的要求都很高,而连杆的刚性比较差,形状复杂,容易产生变形,因此在安排工艺过程时,就需要把各主要表面的粗精加工工序分开,并使工序集中。逐步减少加工余量、切削力及内应力的作用,并修正加工后的变形,就能最后达到零件的技术要求。设计气门摇杆轴支座零件的机械加工工艺规程及铣左端面工艺装备夹具设计,使我学习到了许多机械加工的专业知识和实践内容。
Abstract
Valve rocker bearing is a major diesel engine parts, diesel engine is a combination of the rocker seat. This article discusses the main valve rocker bearing the processing technology and fixture design. Valve rocker bearing accuracy of the size, shape and location precision accuracy of the requirements are very high, and the rigid linkage relatively poor, the shape complex, prone to deformation, in the process of arrangement when it needs to the surface of the main crude Finishing processes to separate and focus on processes. Gradually reduce Jiagongyuliang, cutting force and the role of stress and deformation of the amendment process, will be able to reach parts of the final technical requirements. Design-valve rocker bearing parts of the machining process of order and milling 3mm groove equipment fixture design process, I learned a lot of machining expertise and practical content.
