三坐标测量机的应用领域及选择方式

YYD
YYD over 14 years ago

          主要用于机械、汽车、航空、军工、家具、工具原型、机器等中小型配件、模具等行业中的箱体、机架、齿轮、凸轮、蜗轮、蜗杆、叶片、曲线、曲面等的测量,还可用于电子、五金、塑胶等行业中,可以对工件的尺寸、形状和形位公差进行精密检测,从而完成零件检测、外形测量、过程控制等任务。

 坐标测量机可根据应用选择有两种方式:手动和自动。如果您只需要检测几何量和公差都比较简单的工件,或测量各种小批量的不尽相同的工件,手动机器是最佳选择。手动测量机的软件也可储存和调用测量程序,从而加快了重复性测量。如果需要检测大批量相同的工件,或要求较高的精度,要选择直接用计算机控制的测量机。数控测量机可自动检测并消除操作者对测量结果的影响。程序驱动意味着可实现无误差的高检测速度。

  公差也非常重要,手动测量机很难达到更小的公差要求,而数控测量机通过其连续的触测使其更适合具有严格公差要求工件的高精度和高重复性要求。

  数控测量机通过安装一个模拟扫描测头,用于测量要求大量的数据来定义它们的几何量的工件,如:齿轮、圆柱体、汽车车身、挡风玻璃的测量。对于那些完全用算术方法CAD定义或是完全未知的工件来说,这些测头能够提供连续的数据采集,并可从部分工件和模型上进行逆向工程。对于非常小轮廓形工件来说,扫描测头因其小的扫描面并需要大量数据来进行定义而成为理想的选择。

  测量机安装的场地也很重要。理想情况是,测量机应尽量靠近生产过程中制造工件的操作者附近安装。这些车间型测量机一般具有友好的用户操作接口,具有与机床类似的控制界面。

  不同型号的测量机可以共同工作。一台计量型的垂直式测量机一般使用的精密计量室,做为产品性能的主仲裁,工作型的测量机使用在生产线,对工件的质量进行评判,并提供实时的统计过程控制,并平滑地与整个制造流程规划进行过渡。
