Turbine blade cover plate height size control mechanism and cover plate height detection device

The utility model relates to a turbine blade cover plate height size control mechanism and a cover plate height detection device. The turbine blade cover plate height size control mechanism comprises a mold core, a longitudinal positioning assembly and a lateral positioning assembly. The longitudinal positioning assembly used for controlling the height of the turbine blade cover plate is arranged on the mold core, the longitudinal positioning assembly comprises at least one main positioning column, and the lateral positioning assembly is installed on the main positioning column. The height size of the blade cover plate is accurately controlled, and defective products are prevented from flowing into the next machining procedure. 本实用新型涉及一种涡轮叶片盖板高度尺寸控制机构及盖板高度检测装置，包括型芯、纵向定位组件和侧向定位组件；所述型芯上设置有用于控制涡轮叶片盖板高度的所述纵向定位组件，所述纵向定位组件包括至少一个主定位柱，所述主定位柱上安装有所述侧向定位组件。本实用新型精确控制叶片盖板高度尺寸，避免残次品流入下一加工工序。
