Tubular part closed end wall thickness detection gauge

The invention discloses a gauge for detecting wall thickness of a closed end of a tubular part, which is suitable for the characteristics that one end of the tubular part and one end of a cylinder structure are open, and the size of the wall thickness of a closed end cannot be detected by adopting a conventional gauge, and accurate detection can not be realized. The detection gauge is based on a part mounting base which is consistent with the shape and size of an inner cavity of a part end, a dial indicator is driven to directly measure the wall thickness of the closed end of the part by detecting a series of movement of each part of the gauge, and the gauge has advantages of light and portable design, convenience and simplicity in use, higher measuring precision, wide application range, easiness in manufacturing, higher popularization and application value and the like. 本发明公开了一种管型零件封闭端壁厚检测量具，适用于管型件及缸体结构一端开敞特征，且无法采用常规量具检测封闭端壁厚尺寸，实现精准检测，该检测量具以与零件端头内腔形状尺寸一致的零件安装座为基准，通过检测量具各部件的一系列运动，带动千分表对零件封闭端壁厚尺寸进行直接测量，具有设计轻巧便
