摘要
在机械工业中，产品由于在质量、效能和可靠性等方面有很高的要求，而且构造特点一般表现为形状复杂、壁雹刚度低、技术要求高等。因此，对它的制造与工艺就显得非常具有挑战性和严格性。
本次设计是针对阀导承的制造与工艺,详细地介绍了该产品的整个加工方案的拟订过程，并针对其中钻孔的工序所需的专用夹具进行了设计。工艺设计中依据现有的条件，仍选用传统的机械加工方式进行编制，但又根据零件斜孔特点及其结构性能的要求,部分按照非常规的加工路线进行加工，更好的确保了产品的质量和技术性能要求，也体现产品的加工特点。另外，在专用夹具的设计中，采用了螺栓联接式夹具体，与传统的焊接式相比，虽然成本略有提高，但更利于夹具以后更换、维修，提高了材料的利用率。此外为次道工序所加工的孔设计的夹具还要考虑到加工的孔是斜孔,夹具还要保证其与水平面的夹角,这也增加了夹具设计的难度。

Abstract
In the machinery industry, the products in the quality, performance and reliability requirements are high, and constructed for the general performance characteristics of the shape of complex, thin-walled, low stiffness, high technical requirements. Therefore, the manufacturing and process it becomesvery challenging and rigorous nature.
The design is for thevalve guide for the manufacturing and technology, detailed description of the product throughout the course of processing programs, and procedures forwhich required a special fixture designed. Process design based on existing conditions, still choose the traditional approach to the preparation of machining, but in accordancewith the characteristics of parts and the structure of their own performance requirements, some of the processing in accordancewith the non-conventional processing routes and better ensure that the products quality and technical performance requirements, but also the characteristics of their products. In addition, the dedicated fixture design, the use of the bolt-type connection specific folder, and compared to traditionalwelded, although slightly higher cost, but it is more beneficial after the replacement of fixtures, maintenance, improve the utilization of the material. In addition to the processing procedure at the hole of the fixture design must take into account the processing of the hole is the slant-hole, jig also its anglewith the horizontal plane,which also increased the difficulty of fixture design.
