托脚托架零件的机械加工工艺规程及钻φ35孔夹具设计说明书
托架机械加工工艺及工装设计
摘 要
本论文通过对托架进行分析,在给定的生产条件下,总结实际生产经验和科学
分析的基础上,由多个加工工艺方案优选制定出加工工艺过程。工艺规程是指导生产
的重要技术文件,实际生产必须按照工艺规程规定的加工方法和加工顺序进行。制定
工艺规程应在一定的生产条件下,以最少的劳动量和最低的生产成本,在规定的期
间内,可靠地加工出符合图样及技术要求的零件。
在编制零件的工艺规程时,提出了相应的夹具,量具和刀具设计任务书。根据任
务书进行夹具的结构设计。确定夹具的结构方案中,在定位、夹紧、对定等各个部分
的结构以及总体布局等方面的几个不同方案中,经过分析比较,确定合理的方案,
最后绘制出夹具总图。就像上述的设计方法,我同样设计了量具和刀具。

Abstract
The graduation thesis analyze to the trestle,seltting at the given production
condition,on the summing up the actual production experience and science analysis base,be
processed by many the craft optimization establish to process planning.The rules of the
craft is the important technique which guide the produce document, the actual production
must rule according to the craft gage distance of process the method and process the in
proper order progress. The parts that establishment craft gage distance is at the request of
under certainly of the production condition, with at least of labor quantisty and minimum
production cost, in the prescriptive the inside of term, process to match drawing and
techniques dependablely.
At the craft gage distance of the establishment parts hour, put forward the
homologous fixture,gauge and tool design mission book. Proceed the construction design
of the fixture according to the mission book. The construction project inside of the certain
fixture, in position, clip tightly, to a few and different project that settle a partial
construction and total layout etc., compare through analysis, make sure the reasonable
project, draw the fixture general drawing finally. As mentioned above, I also designed rule
and knife.
Key words: process planning sheduling fixture manufacturing gauge tool
