Description

一种曲轴锥度长度测量装置 技术领域
本发明涉及一种曲轴检测工具，更确切地说，是一种曲轴锥度长度测量装置。
背景技术
曲轴或曲柄零件在输出端常设有锥度结构，如图4所示，锥度面至曲柄平面的长度为锥度长度，一般公差带为0.2mm～0.3mm，原始检测方法为游标卡尺检测或者三坐标检测，游标卡尺测量虽然方便但因为锥度与杆径部位为圆滑过渡，测量点难以固定，加之测量误差，所测量的数据未尽准确，三坐标检测属于精密检测仪器，需要专门送检，耗费时间长，确认结果慢，锥度长度值不能有效获取和验证。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种曲轴锥度长度测量装置。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种曲轴锥度长度测量装置，其特征在于，所述的曲轴锥度长度测量装置包含一平板和一检测组件，所述的检测组件包含一锥度盘，所述的锥度盘的上表面的边缘设有一安装槽口，所述的安装槽口上设有一安装孔，所述的锥度盘的底部中心设有一贯穿的锥形的锥度腔，所述的安装槽口上设有一可拆卸的固定块，所述的固定块上设有一第一固定孔和一第二固定孔，所述的第一固定孔内设有一可拆卸的百分表，所述的锥度盘的下方设有一连接测量杆，所述的连接测量杆的内部设有一连接螺纹孔，所述的百分表的指针与所述的连接螺纹孔固定连接，一固定螺钉分别贯穿所述的第二固定孔和安装孔。
本发明的曲轴锥度长度测量装置具有以下优点：本发明的曲柄类锥度长度检测装置能够快速高效的解决游标卡尺测量不准确和三坐标检测费时费力的问题，在线对曲轴或曲柄类的锥度长度进行检测确认，以产品质量得到管控，提升产品品质稳定性，同时也提高了生产效率。
