[原创]把Meffert's二阶改装成弹簧结构（参赛作品）

一叶知秋

Meffert's 二阶买来转了一星期后，整体感觉很松散了！遂有了要改成弹簧结构的想法 ^_^

问了老大，说是Meffert's 二阶在国内尚无人改成功过，这更勾起了我的好奇心！

一、总体构思：    

拆去八个角块，发现M2里面的小循环是三阶捆绑而成，轨道只有三面可以活动，可以活动的三个面的十字轴中间，是卡榫结构的固定栓（不是螺栓），而且三个卡榫的卡口就集中在十字轴的中心点上，离卡口1/3处还有个肩夹的设计，要想加弹簧就得把卡榫结构的固定栓的卡口给锯掉，和把离卡口1/3处的肩夹疏通（磨损后间隙在弹簧作用下能够变小）。使得固定栓在十字轴上可以自由转动和伸缩。

此结构的优点是：新品转动超级灵活。缺点是：磨损后间隙无法改小。

三个卡榫的卡口就集中在十字轴的中心点上，中心点的旁边有个空间可以容下弹簧。我起先想在这里安装三个弹簧，但是三个轴通过的是同一个点，弹簧之间互相抵触，难以产生弹力效果。后来想到三个轴是相互成90°的直角坐标状，何不把三支弹簧合并成一支一起作用呢！弹簧与三个轴各成135°角，螺栓之类的结构在这里不能起作用了，就选用细钢丝来传递弹力，细钢丝一头连接弹簧上面的帽头，帽头上钻有两孔，让钢丝对折通过，另一头穿透卡榫结构的固定栓，此时压缩弹簧，调整好细钢丝长度后留5~6mm放余量折弯，折弯处用插销固定。为了能让弹簧稳定的起作用，我做了个一端三角形一端圆柱型中空的弹簧底座（既稳定了弹簧，又能使得三根细钢丝索合并通过弹簧内部）。

这是思路图片，只是说明一下问题，具体操作在后面

因为图片过大，我的裁图水平不过关，分两图传上来，让大家见笑了

二、制作工具：    

      Φ1；Φ2：Φ4.8 的钻头

 

三、制作材料：

    ①　细钢丝选用丝织机换下的（俗称：棕丝），是两根粘在一起，扁体的，因为单根比较细小，我就没有撕开，笔直，很容易操作。

    ②  弹簧是三相异步电机控制接触器里面拆下来的，规格：Φ0.7*Φ8*22mm

    ③  弹簧底座选用的是推杆式汽缸的进气连接螺栓（铜制，中空）稍加打磨后即成。

    ④  弹簧上面的帽头是用0.5mm厚的不锈钢板材，剪下比弹簧直径稍大的圆片，因为弹簧直径是Φ8，找一根Φ8的铁棒和一块铁板，在铁板上钻Φ9.0左右一孔，把剪好的圆片放在孔上，用Φ8的铁棒一冲成型。帽头上面的两个穿钢丝的孔是用Φ2的钻头打出。

    ⑤  三个插销用Φ0.7弹簧制成S型，一端成45°，稍微磨尖，便于操作，另一端成直角。

<P>哈哈，顺路去修车行向老板要了个带管的喷头！好东西！用着就是爽~~！</P>
<P>&nbsp;</P>
<P>五、总结：</P>
<P>&nbsp;</P>
<P>此结构的不足之处：</P>
<P>&nbsp;</P>
<P>①　弹簧拉力不能微调。（只能是换弹簧,软一点的手感才好）我也是换到第三根才感觉比较满意的，弹簧底座的圆柱长度可以配合弹簧长度调整弹力的。</P>
<P>&nbsp;</P>
<P>②　折弯钢丝时不容易控制长度。这个就看你的精工水平喽~~注意要用尖嘴钳的平面来折才平整，不能用有齿的部分来折。</P>
<P>&nbsp;</P>
<P>最后的插插销也是个细工活，我一开始钢丝留得较长，安装插销很容易，弊病就是棱块要出轨。理论上分析，留1mm弹力范围是允许的，因为此结构是一动群动的，一根钢丝受力后，弹簧被压缩1mm，另外两根自动放松1mm，作用在各个块上的游隙至多是3mm，而块的滑道宽是4mm，应该还是保险的。所以安装的时候弹簧要压缩到底(弹簧底座的圆柱会顶住），折弯钢丝的时候可以在折痕外打弯。（多试几次就可以掌握）~~~~</P>
<P></P>
<P>&nbsp;</P>
<P>总算又更新了一次，只是有些图片拍得不是很理想 </P>
