1、 尾座体加工工艺及夹具设计尾座体加工工艺及夹具设计 毕业设计（论文） 摘 要 I 摘 要 本课题主要是设计某机床尾座体的加工工艺及夹具的设计， 在设计中采用先 设计该尾座体的加工工艺在根据加工工艺来选取夹具的设计的方案和夹具的具 体设计；而设计的重点是夹具的设计。由于工件的孔 17 和 14 都要以底面做为基 准加工，故首先得做出底面的加工夹具。由于孔 17 的精度要求高，和定位尺寸 误差小， 为保证孔的位置和加工准确性我们一定在加工底面的时间通过画线找出 底面的加工余量。这样就可以更好的保证孔 17 的位置和加工精度！加工孔 14 的夹具其实就是在加工底面夹具的基础上加了一个 45 度斜度板
2、。 加工孔 17 的时 间为保证相对于A和B面的平行度我们就得要准确的设计出以 A和B面定为的夹 具！还考虑到工件的圆度和圆柱度的误差小，我们设计的夹具就具有对孔 17 的 夹具定位准确，和加工时间的震动小，那就得在孔 17 的附近找个定位加紧点！ 关键词 加工工艺，夹具，尾座体，设计 攀枝花学院本科毕业设计（论文） ABSTRACT II ABSTRACT This topic is mainly design that designs the tail a body of some tool machine to process the craft and tongses, adoptin
3、g to design first in the design a body of that tail processes the craft at according to process the craft to select by examinations the tongs of the project of the design and concrete design of the tongs;But the point of design is the design of the tongs.Because the bore of the work piece 17 and 14
4、all want to face to be used as the basis to process with the bottom, past have to do a bottom to face first of process the tongs.Because bore 17 of accuracy have high request, and position the size error margin small, for guarantee the position of the bore and process the accuracy we certainly at process the bottom to face of time pass to draw the line to find out the bottom to face of process the amount of remaining.Thus can wit
