摘要
本设计是关于可变轴距多轴钻床的设计。设计一种钻床用钻轴均布可调多轴头。该多轴头各轴在圆周方向均布却可方便地沿直径方向同步调整，普通钻床为单轴机床，但安装上多轴箱就会成为多轴的钻床，改造成多轴钻床后，能大大地缩短加工时间，提高生产效率。本设计涉及一种可调间距的多轴钻床，包括机身，底座，工作台，主电机，主轴箱设置在机身上并位于工作台的上方，所述的主轴箱内设有万向节，万向节的上端通过齿轮或带轮与主电机相连接，万向节的下端与钻头主轴相连接，设计内容包括齿轮分布与选用、轴的设计、多轴箱的选用、导向装置设计等。不过国内现在多轴钻床传动箱大都采用万向节连杆式传动结构，其缺点是钻杆位置调节由万向节和连杆实现，调节麻烦，调节位置不准确，万向节的存在还使传动箱的轴向尺寸增大，传动刚性很差，这些缺点都可使工件孔的位置精度和尺寸精度不易保证，造成装配困难。

Abstract

This design is about the variable wheelbase multi-axis drilling machine design. Introduction of a drilling machine drill shaft can be adjustable multi spindle heads. The multiple spindle axis in are uniformly distributed in the circumference direction can easily along the diameter direction synchronous adjustment, the ordinary drill is a single axis machine tool, but mounted on the spindle becomes a multi-axis drilling machine, transformed into a machine, can greatly shorten the processing time, improve production efficiency. The utility model relates to a adjustable multi spindle drilling machine, comprising a body, do more, work table, the main motor, the spindle box is arranged in the body and is positioned on the worktable, wherein the spindle box is provided with a universal joint, the upper end of the universal joint through gear or belt wheel is connected with the main motor, universal joint the lower end of the drill bit is connected with the main shaft, the design includes the selection and distribution of gear wheel, shaft design, selection of the multiple spindle heads, guiding device design. But now the domestic machine transmission box adopts universal joint connecting rod type transmission structure, its disadvantages are the drill rod position adjustment by the universal joint and the connecting rod to realize the trouble, regulation, regulation of position is not accurate, universal existence also causes gearbox axial size increases, drive rigidity is poor, these shortcomings can make the workpiece bore location accuracy and dimensional accuracy can not be guaranteed, causing difficulty in fitting.
