一种检具

Testing fixture

Abstract

The utility model relates to a testing fixture comprises bottom plate, slide, float post, pressing tongs, flange ring, measuring round pin etc. During the use with workpiece setting on testing fixture, make unsteady posts I and II cooperations on the unsteady post on two location taper holes and the testing fixture on the work piece, the up end of slide I and slide II respectively with the work piece on the planes of two location taper holes develop, simultaneously, the top of support column I and support column II can be respectively with the work piece on two strong points contacts, this moment the work piece by positioned exactly, compress tightly the work piece with pressing tongs I, pressing tongs II and pressing tongs III. The utility model discloses in use can measure the position degree in knuckle work piece centre bore hole to whether can measure the relative altitude that work piece flange plane phase orders to X orientation qualified, simultaneously, have simple structure, performance safety and stability, high, the cost of manufacture low grade characteristics of detection precision.
本实用新型一种检具,由底板、滑座、浮动柱、压钳、法兰环、检测销等组成,使用时将工件安装在检具上,使工件上的两个定位锥孔与检具上的浮动柱Ⅰ和浮动柱Ⅱ配合;滑座Ⅰ和滑座Ⅱ的上端面分别与工件上两个定位锥孔的平面贴平;同时,支撑柱Ⅰ和支撑柱Ⅱ的顶端会分别与工件上的两个支撑点接触,此时工件被完全定位,用压钳Ⅰ、压钳Ⅱ以及压钳Ⅲ将工件压紧。本实用新型在使用中能够测量转向节工件中心孔孔的位置度,并且能够测量工件法兰平面相对于X方向定位点的相对高度是否合格;同时,具有结构简单、性能安全稳定、检测精度高、制作成本低等特点。
