摘 要
本设计主要围绕发动机曲轴的工艺规程和专用夹具设计进行研究，其内容包括了解曲轴结构，确定曲轴的生产类型，相关的技术要求。在此基础上，选择毛坯，确定毛坯的尺寸公差和机械加工余量，绘制毛坯图。CAD绘制标准零件图，并在认真详细分析零件图后，进行基准的选择，制定了表面加工方法，划分加工阶段，根据生产类型确定工序的集中和分散，合理地安排工序，编排合适的工艺路线；进行详细的大量计算，包括：加工余量、工序尺寸和公差的确定、切削用量的计算及时间定额的计算。从而制定出一套合理的机械加工工艺卡片和机械加工工序卡片。
第二部分的设计是本课题的重点也是难点，主要围绕专有钻床类夹具的设计，用卧式双面中心孔钻床，为铣断面打中心孔这道工序设计一钻床夹具。首先明确夹具设计的主要任务，通过确定定位元件，导向装置，夹紧机构得出夹具的结构方案，查阅相关国家标准，绘画夹具装配图。
本课题研究的发动机曲轴应用在汽车发动机中，
总之，曲轴加工工艺的安排以及专用夹具的设计是一项非常复杂的高难度工作，。它是一种需大批量生产的零件。且技术要求比较高，为了确保产品的质量和水平，设计工作按照科学的程序进行，分清主次，合理取舍。

Abstract
The design was studied that was focused on transmission with the shift fork of the protocols and proprietary drilling fixture design, whose contents were included that the use of blades, the blades type of production and the relevant technical requirements. On this basis, the rough was chosen, and the size of the rough was determined, and the mechanical allowances were determined. A rough map was drawn. After carefully detailed analysis of the parts map, the benchmark was chosen, the development of surface processing methods was determined, and the demarcation of the processing stages was divided. According to the production process the type of centralization and decentralization was determined, the process was reasonably arranged, and the order and orchestrates a suitable process line were set up. Then some detail was calculated, such as allowance, processes size and the determination of tolerance. The amount of calculation and the calculation of the fixed time was cut. Thus a set of reasonable card processing machinery and mechanical processes cards were drawn up.
The second part of the design was the focus of this issue which was difficult, who was mainly centered on proprietary drilling fixture design, Z525-use vertical drilling, drilling screw hole design process by which a drilling fixture. Firstly fixture was designed to clear the major tasks identified by positioning components, guidance devices, clamping body fixture structure, access to the relevant national standards, painting fixture assembly.
The study of the subject transmission blades was used in the transmission gearbox shift agencies. Through the design of the transmission plectrum shift gearbox bodies changed stalls, thus it changed the speed of automobile.
This paper transmission plectrum design of technical rules, transmission truly achieved the change stalls and shift function, against drilling fixture design, realization of the drilling screw hole of this procedure.
In short, the design of transmission plectrum was a complex task. It was the typical products in mass production. To ensure the quality of products and the level of design the work must be produced in accordance with the scientific procedure, prioritize, reasonable choice
Keywords: Plectrum, machining, technical rules, manufacturing technology, fixture
