Description

一种花键轴凸缘叉一体化生产工艺
技术领域
本发明涉及传动轴总成装配工艺领域，具体为一种花键轴凸缘叉一体化生产工艺。
背景技术
花键轴是机械传动一种，和平键、半圆键、斜键作用一样，都是传递机械扭矩的，在轴的外表有纵向的键槽，套在轴上的旋转件也有对应的键槽，可保持跟轴同步旋转。在旋转的同时，有的还可以在轴上作纵向滑动，如变速箱换档齿轮等。
在现如今的传动轴总成装配工艺中，大多数企业还是采用人工或者人工操作机械的方法，并且花键轴和凸缘叉都是分开铸造的，这样不仅投资高，还十分耗费人力物力，同时不能完全保证花键轴和凸缘叉的质量，同时降低了生产效率。

本发明的目的在于提供一种花键轴凸缘叉一体化生产工艺，以解决上述背景技术中提出的问题。
本发明的目的是通过下述技术方案予以实现:一种花键轴凸缘叉一体化生产工艺，具体工艺步骤如下：
第一步：将合金钢加热至熔点得到合金钢溶液；
第二步：将合金钢溶液放置花键轴模具和凸缘叉模具中，冷却成合金钢固体工件；
第三步：将合金钢固体工件缓慢升温至900℃，保持3小时，随后进行退火；
第四步：将退火后的合金钢固体工件再次加热进行双液淬火：
第五步：将进行双液淬火后得到的合金钢固体工件进行正火工艺，随后进行有机溶液淬火，等待冷却后进行工件表面淬火，得到半成品花键轴凸缘叉；
第六步：采用脉冲扫描仪对半成品花键轴凸缘叉进行扫描；
第七步：采用五轴联动数控机床对半成品花键轴凸缘叉进行加工；
第八步：将加工过的半成品花键轴凸缘叉进行化学镀，得到花键轴凸缘叉一体件。
与现有技术相比，本技术方案使传将花键轴和凸缘叉结合成一体件，采用模具铸造的方法，同时采用淬火技术，并且使用脉冲扫描仪对工件进行扫描，采用五轴联动数控机床进行加工，同时提高效率，保证质量。
