毕业设计（论文）-杠杆零件工艺及铣台阶面夹具设计.doc

常州机电职业技术学院毕业设计(论文)说明书作者: 学号: 系部: 专业: 题目: 杠杆零件工艺及铣台阶面夹具设计指导者: 评阅者: 年月毕业设计(论文)中文摘要本设计是基于杠杆零件的加工工艺规程及一些工序的专用夹具设计。杠杆零件的主要加工表面是外圆,台阶面及孔。一般来说,保证平面的加工精度要比保证孔系的加工精度容易。因此,本设计遵循先面后槽的原则。并将孔与平面的加工明确划分成粗加工和精加工阶段以保证孔系加工精度。主要加工工序安排是先以支承孔系定位加工出顶平面,在后续工序中除个别工序外均用顶平面和工艺孔定位加工其他孔系与平面。夹具选用专用夹具,夹紧方式多选用手动夹紧,夹紧可靠,机构可以不必自锁。因此生产效率较高。适用于大批量、流水线上加工。能够满足设计要求。关键词: 杠杆类零件;工艺;夹具全套图纸,加 153893706 I 毕业设计(论文)外文摘要 Abstract : This design isthe special fixture for machining process for long shaft parts and process design based on. The main processing surface oflong shaft parts iscylindrical and holes. Ingeneral, ensure the machining accuracy ofplane than toensure the accuracy ofthe processing easily. Therefore, follow the groove surface after the first principle ofthe design. And the hole and the plane processing clearly divided into roughing and finishing stages toensure machining precision. The main process ofmachining technology isfirst tosupport hole positioning processing the top plane, inaddition tothe follow-up processes are individual processes with the top plane positioning technology and other processing Kong and plane. The special fixture fixture, clamping means more choice ofmanual clamping, clamping reliable, agencies can not self-locking. Therefore, higher production efficiency. Suitable for large batch, the processing pipeline. Can meet the design requirements.
