毕业设计说明书 设计（论文）题目：变速器结合盖机械加工工艺规程及指定工序专用夹具设计（大批量） 学生姓名： 学 号： 专业班级： 学 部： 指导教师： 年 月 日 摘 要 汽车变速器左侧盖是汽车变速箱的重要组成部分。它与变速箱箱体装配，为变速箱内部的齿轮，轴等工作元件提供一个稳定的安全的工作环境，防止内部零件在暴露环境下工作。 本设计要求“以质量求发展，以效益求生存”，在保证零件加工质量的前提下，提高了生产率，降低了生产成本，是国内外现代机械加工工艺的主要发展方面方向之一。 Abstract Automobile speed aviator left cover is an important component of the gearbox. Box it and gearbox assembly, the internal gear for the transmission, axle components,and other word. It provides a stable and secure working environment to prevent exposure of internal components in the working environment. This Paper requires that with quality beg development, with benefits seek to live on to store , under the prerequisite of guaranteeing the quality of element processing , have raised productivity and reduced production cost, is one of mainly direction of domestic and international modern machining technology developing. Make the starting point of the process route, is to make the parts shall be geometric shape, size precision technology requirements get reasonable guarantee. In the production program has determined to be under the premise of mass production, can consider to use sex machine tools match with special jig, and try to make process to improve on productivity. In addition, also should consider economic benefit, so as to reduce the production cost as much as possible, in short, in making the process route when, should follow: high quality, high yield, low consumption principle, that make the process route in the current conditions the most reasonable Through knowing and analysis the the left side transmission cover part drawing for transmission, so as to analysis the process, make process explanation and analysis the technical requirement and the precision of the left side transmission cover. Then, carry out the design of clamping apparatus and analysis the precision and error for the processing of the contact plane of left side transmission cover, this technology and t
