一种异型工件检测用夹具
本技术涉及一种异型工件检测用夹具。
技术介绍
工件在完成加工后一般都需要对其尺寸进行检测,以确保工件的加工精度。由于工件尺寸大小和形状各式各样,变得越来越不规则,我们即称之为异型工件。异型工件的形状不规则,在对异型工件的尺寸进行检测时,现有的夹具在对其进行固定时的操作较为繁琐,且夹持工件的稳定性较差。
技术实现思路
本技术的目的在于提供一种异型工件检测用夹具,其结构合理,能有效的夹持异型工件,以便对异型工件的尺寸进行检测。为实现上述目的,本技术的技术方案是设计一种异型工件检测用夹具,所述异型工件整体呈环状,该异型工件的外壁上部设有径向向外凸出的环形凸檐,该环形凸檐上均布有若干通孔;所述夹具包括底座以及与所述若干通孔一一对应的若干支撑块,所述底座呈圆盘状,该底座外壁面上均匀设置有若干定位槽,该若干定位槽与若干支撑块一一对应,所述若干支撑块分别卡接在对应定位槽上,各支撑块顶面高于底座顶面,且各支撑块顶面设有螺纹孔;所述异型工件的环形凸檐平置于支撑块上,且环形凸檐上的通孔与对应支撑块上的螺纹孔共轴心,各通孔中穿设有双头螺钉,各双头螺钉下端的螺纹与支撑块上的螺纹孔连接,且各双头螺钉上端的螺纹连接有锁紧螺母。优选的,所述锁紧螺母与环形凸檐之间设有垫片。优选的,所述底座上设有中心孔以及沿中心孔周向均布的若干减重孔。优选的,所述底座上设有两个以中心孔对称的吊耳。本技术的工作原理为:装夹时,将异型工件的环形凸檐平置于支撑块上,并使环形凸檐上的通孔与支撑块上的螺纹孔相对应,然后通过双头螺钉和锁紧螺母将环形凸檐压紧在支撑块上,从而将异型工件固定;并且,通过在锁 ...
