机械式低频振动钻削装置设计
摘 要
我的毕业设计题目是机械式低频振动钻削装置设计。通过该装置使工作台产生振动频率为100Hz，200HZ，300Hz，固定振幅为0.05mm的振动。
电动机经一级皮带传动，使输入轴产生一定的转速，输入轴通过齿轮啮合使中间轴产生更高的转速。在中间轴上有三个不同的齿轮，三联滑移齿轮通过导向花键连接在输出轴上，这个三联滑移齿轮可移换左、中、右三个位置，使传动比不同的三对齿轮啮合，因而中间轴转速不变，输出轴可以得到三级不同转速。偏心轮安装在输出轴上，推动推杆上下往复运动，推杆另一端顶着工作台，通过调整偏心轮的偏心距，使得推杆产生0.05mm的振幅，即工作台产生0.05mm的振幅。

Abstract
The title of my graduation design is mechanical low frequency vibration drilling device design. The device makes the working table vibration frequency of 100Hz,200HZ,300Hz,0.05mm fixed amplitude vibration.
The motor through a belt transmission, the input shaft to produce a certain speed, the input shaft through the gear of the intermediate shaft to generate higher speed. On the intermediate shaft with three different gear, a triple slide gear through a guide connected through splines on the output shaft, the triple gear shift left, right, in three position, The transmission ratio of gear meshing with three different, so the intermediate shaft rotating speed, the output shaft can be three at different speed. Eccentric wheel mounted on the output shaft, push up and down reciprocating motion, rod against the table, by adjusting the eccentric distance of the eccentric wheel handspike, makes the 0.05mm amplitude, i.e. table have 0.05mm amplitude.
