柱塞泵连杆制造工艺及其工艺装备设计

柱塞泵连杆制造工艺及其工艺装备设计(任务书,开题报告,毕业论文说明书16000字,CAD图纸3张)
【摘 要】    连杆零件是柱塞泵的主要传动件之一，本文主要论述了连杆的加工工艺及其夹具设计。连杆的尺寸精度、形状精度以及位置精度的要求都很高，而连杆的刚性比较差，容易产生变形，因此在安排工艺过程时，就需要把各主要表面的粗精加工工序分开。逐步减少加工余量、切削力及内应力的作用，并修正加工后的变形，就能最后达到零件的技术要求。

Manufacture technology of piston pump connecting rod and design of its process equipment
【ABSTRACT】   The connecting rod is one of the main driving medium of diesel engine, this text expounds mainly the machining technology and the design of clamping device of the connecting rod. The precision of size, the precision of profile and the precision of position , of the connecting rod is demanded highly , and the rigidity of the connecting rod is not enough,easy to deform, so arranging the craft course, need to separate the each main and superficial thick finish machining process. Reduce the function of processing the surplus , cutting force and internal stress progressively , revise the deformation after processing, can reach the specification requirement for the part finally

【Keyword】: Connecting rod  clamping device
