The utility model discloses a pin hole symmetry gauge, including installation seat, installation seat is provided with a shaft to be measured and matched to the mounting hole and shaft to be measured, installation bolt holes. Also included with the pin hole, the outer round surface of the symmetrical degree is qualified to detect pin hole to the mandrel axis, the installation seat is also provided with a measuring hole, and detection of mandrel, measurement of bolt holes and the axis and the axis of the mounting hole and the vertical intersection. Detection of mandrel used in the detection by one side of the measuring hole arranged on the mounting hole to be inserted into the pin hole measuring axis whether can the other side out of the hole by measuring the test pin hole on the axis of the outer circle of the symmetry is qualified. The utility model of the pin hole symmetrical degree detector to detect the pin hole on the axis of the outer circle of the symmetry is qualified, simple and rapid operation, can quickly determine the measured pin hole on the shaft to pass the outer circle of the symmetry, and high detection efficiency.

销孔对称度检具
本技术涉及轴类零件加工领域,特别地,涉及一种销孔对称度检具。
技术介绍
细长空心轴类零件,如附图图1所示,该待测轴10长约150mm,外圆直径约φ12mm,内孔直径约φ9.1mm,外圆表面加工有4个直径为φ3mm的销孔101,4个销孔101沿待测轴10的同一条母线依次布置,且各销孔101垂直贯穿待测轴10,销孔101对待测轴10的外圆面102的对称度为0.03。现有技术中,检测销孔101对待测轴10的外圆面102的对称度是否合格时,首先使用夹具固定装夹待测轴10,然后采用检测芯棒穿过销孔101,并使检测芯棒的两端均外露销孔101,接着采用千分表对检测芯棒的两端打表调平,然后再翻转夹具180度,重新对外露销孔101的检测芯棒的两端打表调平,最后根据千分表的读数判断销孔101对待测轴10的外圆面102的对称度是否合格。整个检测过程操作繁琐,检测时操作步骤多,需要不断打表调平,故而检测时操作难度大、检测效率非常低,且对工人的操作技能有一定要求,检测结果受操作人员影响大,检测结果不稳定。
