WP-13发动机吊挂支架的工装设计 摘 要 在机械制造企业的生产过程中，夹具被广泛应用于机械加工、检验、装配、焊接及热处理等冷、热加工工艺中，用以安装加工对象，确保加工对象正确的加工位置。其中应用最为广泛的是金属切削机床中的夹具，我们称之为机床夹具。它在发挥设备潜力，确保优秀的产品质量、提高产量的同时降低成本，以及方便加工工人掌握复杂零件和精密零件的加工技术，以减轻加工工人劳动量等方面发挥着巨大的积极作用。因此，机床夹具在机械加工中是一种重要的工艺装备。[2] 根据任务说明书的要求，本毕业设计论文针对WP-13发动机吊挂支架的工装设计进行说明。主要内容是通过对WP-13吊挂支架零件尺寸精度、位置精度和几何精度的工艺分析，根据已经制定的工艺路线，在保证加工表面对其他表面满足要求的尺寸和位置精度的前提下，对定位、夹紧进行正确选择。查阅资料，结合资料和以往经验进而设计N055钻铰孔和N0120镗球面的专用夹具。本设计力求正确、实用、简单，满足提高劳动生产率、降低劳动强度、保证加工质量的基本要求。 关键词：吊挂支架、机床、夹具设计 The design of the WP-13 engine?mounted?hanging support爓ork 架Abstract:In the process of production machinery manufacturing enterprises, the fixture is widely used in mechanical processing, inspection, assembly, welding and heat treatment, such as cold, hot working process, to install the processing object, ensure machining position of object correctly. One of the most widely used in metal cutting machine tool fixture, we call it for machine tool fixture. It in play equipment potential, to ensure excellent product quality, improve production and reduce cost, and convenient processing workers master the complex parts and precision parts processing technology, in order to reduce processing workers labor aspects play an enormous positive role. Therefore, machine tool fixture is an important process in the mechanical processing equipment. According to the requirement of the task description, this graduation design paper for WP - 13 engine hanging bracket tooling design. Is the main content of WP - 13 hanging bracket parts dimensional accuracy, position accuracy and geometric accuracy of process analysis, according to already make craft route, the guarantee to meet the requirements of other surface machined surface under the premise of size and location accuracy, correct selection of positioning, clamping. Check data, combined with data and past experience and design N055 drilling and reaming and N0120 boring spherical special fixture. This design makes every effort to correct, practical, simple, improve
