Compact form hole sealing mechanism rises

The utility model relates to a compact form hole sealing mechanism rises belongs to part sealing performance or lets out leakage quantity's detection technique technical field. This compact form hole sealing mechanism rises comprises dabber, sealing ring, spacing sleeve, main shaft cover, elastic component, jump ring, pin, the power supply passes through threaded connection to be promoted the main shaft cover and removes, the unevenness end face contaction of spacing sleeve one side and workpiece for measurement at first, and after this the dabber through the pegging stops to remove with spacing sleeve, and the main shaft cover is then continue to remove to the crush seal ring makes the sealing ring warp, thereby reaches the purpose of the tight hole shutoff of rising. This patent adopts the hole compact form sealing method that rises, has solved the difficulty of the unable shutoff of cavity spare terminal surface. 本实用新型涉及一种涨紧式内孔密封机构，属于零件密封性能或泄漏量的检测技术技术领域。该涨紧式内孔密封机构由芯轴、密封环、限位套筒、主轴套、弹性件、卡簧、销子组成；动力源通过螺纹连接推动主轴套
