基于proe的气门摇臂轴支座机械加工工艺规程及夹具设计
摘要
专用夹具在现在的机械加工过程中发挥着重要的作用，实现了加工件的定位和夹紧。本次设计研究的对象是气门摇臂轴支座。该零件是柴油机控制系统中不能缺少的零件之一，为柴油机能够调节气门以及正常工作提供保障。主要研究的内容包括零件的加工工艺设计、专用夹具以及夹具三维实体建模的设计。
在对加工工艺设计之前，首先完成了零件作用及零件图的分析，确定了零件的生产类型，制造方式及加工余量，绘制毛坯图。设计加工工艺路线，计算工序卡中涉及到的切削用量等。最后，完善了工艺卡及工序卡。
本次加工的零件设计钻Φ11孔钻床专用夹具。设计的内容为：确定零件的定位方案；选择夹紧装置还有夹紧元件；对夹具体进行了设计和确定；为保证零件的加工精度，选择对刀装置—钻套；对零件在装夹过程中的夹紧力和切削力进行计算等。利用Proe三维建模软件完成夹具的三维实体建模。完成专用夹具的夹具装配图还有所有非标准的零件图。

Abstract
Special fixtures play an important role in the current machining process, enabling the positioning and clamping of theworkpiece. The object of this design study is thevalve rocker shaft support. This part is one of the indispensable parts in the diesel engine control system,which guarantees the diesel engine can adjust thevalve and normalwork. The main research contents include the machining process design of parts, special fixtures and the design of 3D solid modeling of fixtures.
Before designing the machining process, the function of the parts and the analysis of the parts drawingswere first completed, and the production type, manufacturing method and machining allowance of the partswere determined, and the blank drawingwas drawn. Design the processing route, calculate the amount of cutting involved in the process card, and so on. Finally, the process card and process card have been improved.
This machined part is designed to drill a special fixture forΦ11 hole drilling machine. The design content is: determine the positioning scheme of the parts; select the clamping device and the clamping components; the specific design and determination of the clamp; to ensure the machining accuracy of the parts, select the tool setting device- the drill sleeve; The clamping force and cutting force in the process are calculated. The 3D solid modeling of the fixture is done using Proe 3D modeling software. Complete the fixture assembly drawing for the dedicated fixture and all non-standard parts drawings.
Keywords:valve rocker shaft bearing; machining process; drillingΦ11 hole; special fixture; Proe 3D modeling
