摘要
本文主要是汽车前钢板弹簧前后支架底五孔钻孔多轴头组合机床设计,多轴头是一个带有多个输出的闭式传动箱,利用它可在立式钻床上进行钻孔、扩孔、绞孔和攻丝等工序加工.由于它的结构简单不需要改变既有机床设备,投资少、见效快因此适应中小批量多孔零件加工
汽车前钢板弹簧前支架底盖有4个Φ14.5的孔后支架底盖有3个Φ14.5孔需同时加工按工艺安排在Z535机床上用一夹具既要能加工前支架4个孔又能加工底盖上3个孔为节省更换多轴头所需的辅助时间故设计一套两种零件都能加工的通用多轴头.这两种零件形状和尺寸大致相同但也有不同处,故需设计一套夹具可以分别满足两种零件装夹和定位.
为提高工效需把普通钻头改成群钻,因此对刀具也要进行必要的设计.这样的结果节约了制造成本、保证了加工质量、提高了生产效率、增加了工人安全操作可靠性.
主要考虑并解决以下主要问题：（1）加工表面要求的精度和粗糙度；（2）工件的生产批量；（3）工件的结构形状和尺寸；（4）钻床改装的实际可能性.对被改装钻床的分析分析被改装钻床时包括的主要内容有：（1）分析机床能否适应改装要求；（2）调查和了解机床的使用情况；（3）考虑机床的动力情况；（4）分析改装后机床的强度和刚度问题.

This paper is mainly auto leaf spring before the before and after five hole drilling stent multiaxial head combination machine tools design, the multiaxial head is a multiple output with closed transmission box, can use it in the vertical drilling machine drilling, reaming, wring holes and tapping the process such as processing. Because of its simple structure don't need to change both machine tool equipment, less investment, quick effect so adapt to small and medium-sized batch porous parts processing
Auto leaf spring before before four base of support Φ 14.5 after the hole of the base of support 3 Φ 14.5 hole shall also processing according to the arrangement of technology in Z535 with a fixture on the machine can not only four holes before processing stent and processing base for three holes to save more for replacement shaft head auxiliary time reason design a set of two parts will be the multiaxial head processing general. The two parts in shape and size of roughly the same but also have different place, reason need to design a fixture can meet the two parts are clamping and positioning.
In order to improve the efficiency of the common to drill to drill, so the tool will make the necessary design. The results of the production cost saving, that ensure the process quality, improve the production efficiency, increase the workers' safety operation reliability.
The main consideration and solve the following main problems: (1) processing surface requirements of precision and roughness; (2) the production batch; (3) the shape and size of workpiece structure; (4) drilling machine refitted practical possibility. The analysis of the drilling machine be modified to be modified analysis when the main content of the drill include: (1) to analyze the machine is ready to adjust to modified requirements; (2) to investigate and understand the use of machine tools; (3) considering the power of machine tools; (4) analysis modified strength and stiffness of the machine tool.
