摘  要

轮对前盖的加工工艺及夹具的设计，包括零件加工的工艺设计、工艺设计和专用夹具的设计三个部分。大家都知道，我们必须在设计过程中，首先对零件的分析，了解设计过程的一部分，然后在好结构，在选择加工基准与零件设计过程的一部分，之后，将每一步的工艺尺寸的计算，在每个阶段的生产工艺主要由过程和减少设备的数量和随后的设计，各种零件的专用夹具设备的设计，如定位元件、夹紧元件、驱动元件、机床夹具，连接元件和其他元件，同时，我们计算设备产品。误差分析的植物结构好，好的和坏的，在未来的设计必须改进。

Abstract

Shell parts processing technology and design of drilling jig design process design, including the parts processing process design and fixture three. In the process of design should first carries on the analysis to the components and parts of the process to understand the design of blank structure, and choose the good components the processing datum, designs the process routes of the parts; then the parts of each step of process dimension calculation, is the key to decide the craft equipment and the cutting dosage of each working procedure; design then the special jig, fixture for the various components of the design, such as the connecting part positioning device, clamping device, guide device, clamp and the machine tool and other components; the positioning error calculate fixture positioning, analysis of the rationality and deficiency of fixture structure, pay close attention to the improvement and design in later.
