一种定起点螺纹检测装置
摘要：
本实用新型公开了一种定起点螺纹检测装置，包括定起点外螺纹检测装置与定起点内螺纹检测装置；所述定起点内螺纹检测装置的螺纹样柱定位台阶的外圆上设有划线刃口，定位台阶的划线刃口与定起点外螺纹检测装置的划线样板的划线刃口重合，螺纹样柱的另一端面为基准面，螺纹样柱的螺纹起点与定起点外螺纹检测装置的螺纹起点样圈的螺纹起点一致。本实用新型结构简单、稳定可靠、测量准确、易操作，能准确检测外螺纹起点位置，并传递到内螺纹，保证零件快速、准确装配。
摘要（英）：

The utility model discloses a decide starting point thread detection device, thread detection device in deciding the outer thread detection device of starting point and decide the starting point, decide to be equipped with on the screw appearance post location step's of thread detection device in the starting point the excircle marking off blade, the marking off blade coincidence of location step's marking off blade and the face template of deciding the outer thread detection device of starting point, another terminal surface of screw appearance post be the reference surface, the screw starting point of screw appearance post with decide the starting point outside the screw sample application of the thread detection device screw starting point of enclosing unanimously. The utility model discloses simple structure, reliable and stable, measure accurate, easy operation, can accurately detect external screw thread starting point position to transmit the internal thread, guarantee quick, the accurate assembly of part.
