螺旋夹紧器机构方案设计.docVIP

PAGE PAGE 19 摘 要 螺旋夹紧器是利用人力作用使螺杆上下做直线运动为原理的简单机械机构,使用起来比较方便，可用于科研、化工、工业等场所。本设计是用于较小工件、零件等机加工时常用的螺旋夹紧器装置,它可以将螺旋运动转换为直线运动，实现使用较小的人力去固定和夹紧物体，从而达到减轻人类劳动、提高劳动生产效率。其工作原理是通过人力作用，将动力传导到螺旋副，使螺杆上下作直线运动达到固定和夹紧作用。 所设计的螺旋夹紧器是以零件的设计计算与校核为主要内容的设计，包括螺旋副、螺杆和螺母的设计计算与校核及其它零部件的选择确定，最后运用AutoCAD软件分别画出所设计的螺旋夹紧器的各个零部件及装配图。 关键词：螺旋，夹紧器，设计 ABSTRACT Screw Clamp is the use of human role to screw up and down to do a simple linear motion machinery for the principle of agency, so that it is more convenient to operate, can be used for research, chemicals, industry and other places. This design is used for spiral clamping device where small parts and machine parts are processed, which can convert the spiral movement to linear motion. It can make an achievement of using smaller manpower to fix and clamp objects. Therefore, human labor is relieved and working productivity is improved. Its principle is that through the manpower, the power is transmitted to the screw to make it up and down in a straight line to reach the effect of fixing and clamping. The main content of the design of the spiral clamp is calculation and checking of machine parts, which include screw pair, screw and nut and other parts’ selection. Finally using AutoCAD software respectively work out all the parts and assembly drawing of the Screw Clamp design.
