紧固螺栓加工工艺设计
摘要
机械加工工艺规程是指导车间生产的主要技术文件、生产准备和管理准备的重要资料、新建或扩建工厂和车间的基本依据、还便于交流与推广先进经验。正确的工艺规程可以稳定地保证产品的质量和获得较高的生产率经济效益、能使生产均衡顺利的进行。
本文给出的零件是紧固螺栓，紧固螺栓是一种很重要也很典型的轴类零件，主要起到传递运动和动力的作用。外圆表面设有键槽、圆柱孔及螺纹等等。通过对零件图纸的分析，培养自己树立正确的对产品的加工能力，完成加工及组装工艺。也可使自己进一步加深对所学理论的认识，学会运用所学知识去分析和解决一些实际问题。
本次设计对紧固螺栓的加工工艺规程进行了详细的分析。制定了加工紧固螺栓的机械加工工艺路线，详细计算了加工余量、切削用量、尺寸公差，确定各工序尺寸、工序加工余量、加工工时、机械加工三要素等，选择其加工设备。通过本设计掌握零件的加工过程分析、工艺卡片的编制和步骤。学会应用手册、标准、规范等资料。认识到工艺在机械制造中的重要性。了解刀具的选用规则，产品质量、精度、寿命等属性和节约材料，降低成本，最重要的是提高生产经验。
关键词：加工工艺、紧固螺栓、工艺路线、工序
ABSTRACT
Machining process planning is to guide theworkshop production of the main technical documents, production preparation and management of important information prepared for fundamental basis for new or expanded factories andworkshops, but also to facilitate the exchange and dissemination of advanced experience. Correct process can be stably procedures to ensure product quality and economic benefits of higher productivity, enabling the production of equilibrium smoothly.
Part of this paper is fastening bolts fastening bolt is avery important andvery typical of the shaft parts, mainly plays the role of transmitting motion and power. The outer surface has a keyway, cylindrical bore and thread, and so on. By drawing parts of the analysis, the right to develop their own set of products processing capacity to complete the processing and assembly processes. Also can deepen their own understanding of the theory, learn to use the knowledge to analyze and solve some practical problems.
The design of the processing procedure fastening boltswere analyzed in detail. We developed a mechanical process line processing fastening bolts, detailed calculation of the allowance, the amount of cutting, dimensional tolerances, determine the step size, step allowance, processing time, machining and other three elements, choose their processing equipment. Through this design master parts machining process analysis, process card preparation and procedures. Society, application notes, standards, specifications and other information. Recognizing the importance of technology in the machinery manufacturing. Learn the rules of the tool selection, product quality, accuracy, life and other attributes, and save materials and reduce costs, the most important is to improve the production experience.
Keywords: Processing technology, fastening bolts, routing, process
