偏心螺杆零件普车加工工艺设计
摘要
零件的加工工艺分析是加工过程中最重要而又极其复杂的环节，必须在普车加工方案制定前完成。普通车床是目前使用最广泛的机床之一。普通车床主要用于加工轴类、盘类等回转体零件。也可以实现加工内外圆柱面、圆锥面、外形表面、螺纹和端面等需要加工的的内容，并且可以进行切槽、钻孔、扩孔、铰孔等加工。
本次设计说明书以普通车床车削典型的偏心螺杆零件为例，根据被加工工件的材料、轮廓形状、加工精度等选用合适的机床，制定加工方案，确定零件的加工顺序，各工序所用刀具，夹具和切削用量等。
关键词：加工工艺；偏心螺杆；轮廓形状；加工顺序；切削用量
Abstract
In the manufacturing process of parts machining process analysis is the most important and extremely complex link, must be finished before the car's processing plan formulation. Ordinary lathe is currently the most widely used one of nc machine tools. Ordinary lathe is mainly used for machining shaft, plate axisymmetrical parts. Also can realize processing inner and outer cylinder, cone surface, surface appearance, such as thread and end face of the machining of content, and can carry out cutting, drilling, reaming, reaming, such as processing.
The design specification to ordinary lathe turning typical eccentric screw parts as an example, according to the shape of the material, the outline of the processed workpiece, choose suitable machine tools machining precision, processing plan formulation, determine the machining sequence of parts, each working procedure used cutting tools, fixture, cutting dosage, etc.
Key words: process; Eccentric screw; Contour shape; Processing order; Cutting parameter
