Abstract
The utility model discloses a nuclear reactor control rod drive mechanism pipe seat omega bevel repair equipment, include: drive system, tool, detection head and locking device. Drive system can drive tool rotates around CRDM pipe seat to process omega bevel to form the machining surface, locking device is used for fixing nuclear reactor control rod drive mechanism pipe seat omega bevel repair equipment in CRDM pipe seat, drive system can drive detection head motion and with machining surface contact to measure the processing accuracy of bevel, therefore when the nuclear reactor control rod drive mechanism pipe seat omega bevel repair equipment of this embodiment is used to repair the omega bevel of CRDM pipe seat, after the processing of omega bevel is completed, can carry out accuracy detection to the machining surface of omega bevel through detection device, need not through other equipment to carry out additional measurement to improve the repair efficiency of omega bevel, and need not manual detection to reduce the risk of manual long -term exposure in high radiation environment.
