Description

一种有速度放大效应及力矩比较功能的机构 【技术领域】
本发明涉及一种运动机构，尤其涉及一种有速度放大效应及力矩比较功能的机构。
【背景技术】
传统地，当采用一个马达或者一个其它动力源而需要两个执行动作时，一般的设计是通过齿轮、凸轮或者连杆机构将一个输入运动转化为两个输出支路，这两个支路同时按设计的周期规律运动，要停止一个执行动作就必须让两个执行动作同时停止；这两个执行动作实际上是“刚性”关联的。
要使上述的两个执行动作具有一定的独立性或者称之为“柔性”，普遍的设计会采用两个马达或者两个其他动力源来分别驱动两个执行动作。这样的设计成本高，采用两个动力源时，其利用率往往不高，而且结构尺寸大，当需要两个动有关联地工作时，需要加传感器及信号处理系统来分别控制两个执行动作按顺序进行，这样反应速度就相对慢了。
【发明内容】
本发明的目的在于解决传统地，当采用一个马达或者一个其它动力源而需要两个执行动作时，一般的设计是通过齿轮、凸轮或者连杆机构将一个输入运动转化为两个输出支路，这两个支路同时按设计的周期规律运动，要停止一个执行动作就必须让两个执行动作同时停止；这两个执行动作实际上是“刚性”关联的，设计成本高，采用两个动力源时，其利用率往往不高，而且结构尺寸大，当需要两个动有关联地工作时，需要加传感器及信号处理系统来分别控制两个执行动作按顺序进行，这样反应速度就相对慢了的不足而提供的一种有速度放大效应及力矩比较功能的机构。

进一步地，还包括拔销，所述拔销位于所述行星轮底座外侧。
进一步地，所述可调节的运动控制装置包括调节螺杆、游标、调节弹簧、滑块，所述游标、调节弹簧、滑块同轴安装在所述调节螺杆上，所述调节螺杆的一端套接在机架上并且所述调节螺杆只能绕其自身的轴线转动，所述调节螺杆的其它自由度被机架限制，所述游标与所述调节螺杆采用螺纹连接，所述游标上有防止转动的结构，转动所述调节螺杆，所述游标沿着所述调节螺杆轴线移动并压缩或释放所述调节弹簧，所述行星轮底座上方设有叉形结构，所述滑块紧邻行星轮底座上方的叉形结构布置，所述调节弹簧的弹力作用在所述滑块上，所述滑块再将所述弹力作用在所述行星轮底座上方的叉形结构上并使行星轮底座上方的叉形结构紧靠所述机架，所述可调节的运动控制装置利用弹力锁定行星轮底座，当行星轮底座被弹力锁定，也就是行星轮轴被锁定，当太阳齿轮转动时，所述行星齿轮只能绕所述行星轮轴作定轴转动，所述行星齿轮带动所述内外齿轮转动，当内外齿轮所受的负载较小时，所述内外齿轮便不停地转动，当所述内外齿轮所承受的负载增大到一定程度甚至被外负载堵转时，所述调节弹簧将被迫压缩，所述行星轮底座将绕所述太阳齿轮中心转动，所述行星齿轮将绕所述太阳齿轮作公转运动或者是所述行星齿轮的自转与公转的复合运动，拧转所述调节螺杆即调节弹力的大小，即可设定行星轮底座运动的阈值。
进一步地，所述可调节的运动控制装置也可以由扭转弹簧、棘轮、棘齿、旋钮组成，通过控制扭转弹簧的扭力设定所述行星轮底座运动的阈值；所述可调节的运动控制装置也可以是恒定的重物的重力，所述恒定的重物的重力作用在所述行星轮底座上，通过控制加载的重力设定所述行星轮底座运动的阈值；所述可调节的运动控制装置也可以是外部输入的其它有源的运动输入，外部输入的其它有源的运动或扭矩作用在所述的行星轮底座上，使所述的行星轮底座或锁定、或正转、或反转；当一个恒定的动力或运动从所述内外齿轮输入，另 一个附加的运动或动力作用在所述行星轮底座上，则所述太阳齿轮输出的运动就是两个输入运动的合成，当改变作用在所述行星轮底座上的输入转速，在所述太阳齿轮上将会得到按比例放大的输出转速，此时，就相当于一个有放大效应“机械式三极管”，因此利用“速度放大效应”来测量低速运转或速度变化的运动，提高测量精度，或利用速度放大效应达到速度控制的目的。
本发明的有益效果在于：
1、提供一个小巧的机构，无需电控系统，便可将一个运动转化为两个独立或相关的运动输出，将它运用于扎带机设计，就可以将一个复杂、笨重的自动扎带“机”简化为一个自动扎带“枪”(手持式工具)；类似地，本发明也可运用在其它需要两路或以上独立或相关的输出的情形中，可使机构大大简化、尺寸缩小、反应迅捷、可靠。
2、提供一个简便的基础设计，通过与不同的控制装置或附加输入运动组合可以实现“力或力矩比较器”、“速度放大器”；
3、提供一个简便的基础设计，类似电器元件中的“三极管”，通过将部分部件并联或将本发明逐级串联或者串、并联的混合可以实现多路或多级的独立的或相关连的输出，运用非常灵活。
4、本发明不仅可以将一个输入运动转化为两个或以上的独立的或相关的输出；可逆地，它也可以将两个或以上的运动合成为一个输出。
5、本发明另外一个有益效果是：选择不同的输入端，两个输出端的旋向或者是同轴同向、或者同轴反向,利用本发明这个特性可以设计出小巧的扭线、扭绳、及缠绕工具。
