摘要
本次设计是对后钢板弹簧吊耳零件的加工工艺规程及一些工序的专用夹具
设计。后钢板弹簧吊零件的主要加工表面是平面及孔。由加工工艺原则可知,保
证平面的加工精度要比保证孔的加工精度容易。所以本设计遵循先面后孔的原
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加工精度。基准
选择以后钢板弹簧吊耳大外圆端面作为粗基准,以后钢板弹簧吊耳大外圆端面与
两个工艺孔作为精基准。主要加工工序安排是先以后钢板弹簧吊耳大外圆端面互
为基准加工出端面,再以端面定位加工出工艺孔。在后续工序中除个别工序外均
用端面和工艺孔定位加工其他孔与平面。整个加工过程均选用组合机床。

攀枝花学院毕业设计(论文) ABSTRACT
ABSTRACT
The design of the plate after spring lug parts of the processing order of the
processes and some special fixture design. Spring plate after hanging parts of the main
plane of the surface and pore. By the principle known Processing , the plane guarantee
precision machining holes than guarantee the machining precision easy. So the design
follows the surface after the first hole principle. Plane with holes and the processing
clearly divided into roughing and finishing stages of processing to ensure accuracy.
After selecting base plate spring lug large cylindrical face as a rough benchmark,
After the leaf spring lug large cylindrical end with two holes as a precision technology
benchmarks. main processes arrangements after the first spring plate lug large
cylindrical face each other benchmarks machined face, End position to further
processing out of holes. In addition to the follow-up processes are individual
processes with end-positioning technology and other processing Kong and plane. The
entire process of processing binations were selected.
Key words The empress steel plate spring coil mourns the ear,Process the
