手电钻省力装置设计(含CAD图,SolidWorks三维图)(任务书,开题报告,外文翻译,论文说明书11000字,CAD图纸2张,SolidWorks三维图24张,仿真视频2个)
摘要
电钻进给力主要靠人提供。为达到省力目的，目前的解决方案都是将电钻固定在电钻夹具上，形成一种小型钻床，但也使电钻失去了原有方便灵活的特性。
本文设计了一类可安装在手电钻上并能灵活使用的装置，该装置使电钻夹具成为电钻的辅件。本装置由电钻固定模块，省力机构，进给机构，装置固定模块组成。根据装置与工件之间不同的固定方式，通过对比分析得出对应的最优方案。
方案一，只适用于钻边缘孔。电钻固定模块，采用环形件套住电钻并紧固；省力机构，采用杠杆原理；进给运动，采用曲柄滑块机构；装置的固定，采用卡爪直接扣住工件底面。省力机构与进给机构复合，在曲柄与连杆连接处，延伸曲柄形成杠杆。
方案二，只适用于平面钻孔且工件粗糙度不能过大的场合。电钻固定模块，采用环形件套住电钻并紧固；省力机构，采用杠杆原理实现；进给运动，采用曲柄滑块机构实现；装置的固定，采用负压吸盘吸附于工件表面。省力机构与进给机构复合，在曲柄与连杆连接处，延伸曲柄形成杠杆。
以方案二思路的延伸,可以设计一种吸附于工件表面具有可移动平台的机床，这将是进一步研究的方向。
本论文提出的是一种可以装在电钻上的省力装置，目的是减轻工人的操作负担。具体的创新点如下：
1、改变传统方式下依靠人提供进给力。
2、在简易的结构下，达到设计要求，本身还能灵活使用。
3、舍弃工作台，将操作范围扩大。

Hand electric drill labor-saving device design
Abstract
Electric drill to force were raised, mainly by people. To achieve energy saving purpose, the current solution is to drill on the drill jig, forming a small drilling machine, but also make the electric drill lost the original characteristics of the convenient and flexible.
This paper design a class can be installed in hand electric drill and flexible use of the device, the device makes a drill jig drill accessaries. This device by electric drill fixed module, save Labour institutions, feed mechanism, unit of fixed modules. According to the different fixed way of between device and artifacts, through the analysis of the corresponding optimal solution are obtained.
Plan a, only applies to the edge of the hole. Electric drill fixed module, using the circular woolly live electric drill and fastening; Institutions, adopts lever principle; Feed movement, the use of slider-crank mechanism; Device is fixed, use the jaw buckle workpiece bottom directly. Energy institutions and compound feed mechanism, the crank and connecting rod joint, extension of crank lever.
Plan b, ionly applicable to the surface of the drill and the workpiece roughness cannot too big occasions. Electric drill fixed module, using the circular woolly live electric drill and fastening; Institutions, adopts lever principle; Feed movement, using slider-crank mechanism; Device fixed, adsorbed on the surface using negative pressure suction cups. Energy institutions and compound feed mechanism, the crank and connecting rod joint, extension of crank lever.
The extension based on the plan b, adsorbed on the surface can design a machine tool with mobile platforms, this will be the direction of further research.
This paper presents a kind of labor-saving devices can be installed on the electric drill, the purpose is to reduce the burden of workers. Specific innovation points are as follows:
1、Change the traditional way to rely on people in under force.
2、Under the simple structure, meet the design requirements, itself can be used.
3、Abandon the workbench, expanded the scope of operation.
Keywords: electric drill ，energy, simple and easy
