Description

轴孔与铣平面垂直度检测工装 技术领域
本发明涉及一种轴孔与铣平面垂直度检测工装，属于工装设备的技术领域。
背景技术
在工件的加工、装配过程中，往往需要对工件的两个结构的垂直度进行测量，确定工件是否满足加工、装配等要求。现有的垂直度测量工具主要是直角尺、三坐标测量仪、线锤、激光测量仪等。这些仪器往往结构简单，可以用于直线与平面，平面与平面之间的测量。但是很多的工件的结构复杂，传统的垂直度检测装置不是不能在工件中放好位置测量，就是测量过程太复杂或者测量工具太昂贵，使得传统的简单垂直度检测装置不能很好应用到工件装配过程中去。有些垂直度的测量装置，虽然可以对工件进行垂直度测量，但是测量的结果不能很直观的展现出来。
 技术问题
本发明目的在于提供一种轴孔与铣平面垂直度检测工装，解决了现有技术存在的垂直度检测装置不能放入工件进行测量，垂直度测量过程太复杂，垂直度测量结果不直观等问题。
 技术解决方案
本发明的上述技术目的主要是通过以下技术方案解决的：
它包括底座，所述底座上设有垂直相交的水平平面和竖直平面，所述水平平面与竖直平面相交处设有竖直通孔，一定位片竖直设置且居于所述竖直通孔中间，所述定位片与竖直平面固定，所述定位片上设有水平通孔，所述水平通孔的轴线与竖直通孔的轴线垂直相交，所述底座上远离竖直通孔的位置设有两个竖直销杆，所述竖直销杆关于所述水平通孔的轴线对称，一呈长杆状结构的检测杆具有一个可插入水平通孔内的插入端，所述检测杆的长度大于竖直通孔轴线到两个竖直销杆的中点的距离，所述检测杆的另一端固定有一个检测杆手柄。
轴孔与铣平面垂直度检测工装主要检测的是带有铣平面与轴孔连通结构的工件。检测过程中，首先把待测工件插入到底座上的竖直通孔中，保证铣平面与定位片紧贴且轴孔与定位片上的水平通孔对准。然后让检测杆的插入端通过轴孔插入到定位片上的水平通孔中。在检测杆的另一端观察检测杆与竖直销杆的位置关系。如果检测杆经过两个竖直销杆的中点，则表示轴孔与铣平面垂直度高。如果检测杆偏向竖直销杆，则说明轴孔与铣平面不垂直。根据检测杆偏向竖直销杆的程度大小，可以直观判断轴孔与铣平面的垂直度是否满足加工、装配等要求。
本发明利用一个远远大于轴孔长度的检测杆，扩大了轴孔与铣平面的微小角度变化带来的边的位置变化，通过与竖直通孔轴线的位置比较直观、快速地对工件进行了垂直度检测。
作为优选，所述的底座上设有一个水平螺纹通孔，所述水平螺纹通孔与所述水平通孔同轴，一固定杆与所述水平螺纹通孔螺纹相配，所述的固定杆设有固定杆把手。
在使用过程中放入待测工件后，拧动固定杆，使得固定杆靠近竖直通孔一端对待测工件进行压紧，从而固定住工件。完成检测工作后，拧松固定杆，就可以取出工件了。在固定杆上设有固定杆把手，使得可以轻松拧动固定杆。固定杆的作用，使得待测工件稳定的放置在了轴孔与铣平面垂直度检测工装上，防止操作过程中产生的轻微抖动与位移对检测结果产生影响。
作为优选，所述固定杆靠近竖直通孔的端部为光滑球面结构。光滑球面结构可以保护待测工件免于损伤和磨损。
作为优选，所述的定位片呈扁平长方体结构。定位片与竖直平面通过两个螺钉固定。采用扁平长方体结构，可以让定位片在下端有一个平面与水平平面接触，可以让定位片的放置更稳定。
作为优选，所述的检测杆的长度大于所述竖直通孔的轴线到设有竖直销杆的底座边缘的距离。在实际的测量过程中，超出底座边缘的定位杆可以方面使用者拔出或插入检测棒。
作为优选，所述的检测杆的插入端为锥度为1：250～1：400的圆台形结构。圆台形结构使得检测杆前端出现锥度，有锥度的检测杆可以容易插入到定位片的水平通孔中去。
作为优选，所述的检测杆由硬质合金材料制成。在检测轴铣平面与孔的垂直度过程中，待检测的工件都是金属材料，在检测过程中很容易对检测工装造成磨损。同时，在检测过程中，检测杆是否笔直对检测结果十分重要。检测杆采用硬质合金材料，使得在长期的使用过程中，提高了检测杆的耐磨损能力，延长了使用寿命。硬质合金材料不容易变形，保证了检测结果的准确性。
作为优选，所述的检测杆手柄的长度关于检测杆的轴线对称。对称的检测杆手柄，使得检测杆的移动平稳。
 有益效果
本发明具有方便、直观的观察到轴孔与铣平面的垂直度关系，能够快速稳定固定待测工件，工装耐磨损等特点。
