1变矩器花键套—零件图A1
摘要
夹具是零件加工的夹紧装置，是加工零件的一种必不可少的装置。夹具利用率高，经济性好，对功能组件的使用和数量少。随着零件的尺寸变化，越来越多的夹具被淘汰了，因此，设计一套专用夹具是十分有必要的。在设计专用夹具时要考虑工件的定位方案，工件的夹紧方案和设计夹紧机构，夹具的其他组成部分，夹具的结构形式等。
本次设计的是对变矩器花键套零件的加工工艺分析及夹具设计。根所选的零件图，在掌握零件作用的基础上，对零件的工艺进行分析。对零件加工过程中铣宽15槽工序进行专用夹具设计。本夹具体是以保证加工精度，生产效率和便于工人操作为宗旨展开的设计。
设计之初我查阅相关数据及国内外关于机床夹具的文献，在看懂零件图的同时对零件的结构和工艺进行分析，明确粗基准和精基准的选择，确定零件的加工余量与毛坯的尺寸、从而确定零件的加工工艺过程、计算各工序的切削用量及工时。最终完成了本次设计所需的夹具。

Abstract
Fixture is a clamping device for parts processing, and it is an indispensable device for parts processing. The fixture has the advantages of high utilization rate, good economy and less use and quantity of functional components. With the size change of parts, more and more fixtures are eliminated, so it is necessary to design a set of special fixtures. When designing special fixture,we should consider the positioning scheme ofworkpiece, the clamping scheme ofworkpiece and the clamping mechanism, the other components of fixture, the structure form of fixture, etc.
This design is to analyze the processing technology of the spline sleeve parts of the torque converter and design the fixture. On the basis of mastering the function of the parts, the process of the parts is analyzed. The special fixture is designed for milling 15 slots in the process of parts processing. This fixture body is designed to ensure the processing accuracy, production efficiency and easy operation forworkers.
At the beginning of the design, I consulted the relevant data and the literature about machine tool fixture at home and abroad, analyzed the structure and process of the partswhile reading the part drawings, made clear the selection of rough and precise reference, determined the processing allowance of the parts and the size of the blank, thus determined the processing process of the parts and calculated the cutting of each process. Dosage andworking hours. Finally, the fixture required for this design has been completed.
Keywords: special fixture; positioning scheme; torque converter spline sleeve; processing technology; cutting parameters
