Problems solved by technology
[0002] After the nuclear power plant has been in operation for a long time, the aging equipment such as internal components of the reactor will have partial defects, and the reliability will be reduced. At this time, these equipments need to be overhauled. For some processing positions that require high positioning and can only be completed in a long-distance underwater operation, at the same time considering the maintenance period and cost, it is necessary to avoid designing, processing and using large-scale positioning devices

Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown in —3, the processing tool 6 can be customized separately according to the specific design requirements and can also be used as a general processing tool on the market, which can be a mechanical processing tool, a hydraulic processing tool, and an electric discharge machining tool, such as: screw taps, reamers, hydraulic pliers, electric pliers, etc. Spark processing heads and other forms. The processing tool 6 and the core rod 16 are connected through a unified interface, and the center of the processing tool 6 is adjusted according to the interface position and design requirements, and the movement in the design direction is completed through the positioning and guiding functions of the positioning frame 10 and the guide device 9 .
[0022] The positioning frame 10 provides connection and fixing interfaces ...

The invention belongs to the technical field of underwater positioning of nuclear power plants, and in particular, relates to a machining device for underwater machining with a precise repeated positioning function. A machining tool, a guide device and an operation extension handle are mounted on a positioning frame; the guide device provides guidance of a motion trajectory to the machining tool; a conversion plate is mounted at one end of the positioning frame; the front end of a V-shaped support is directly contacted with machined equipment, and back end is mounted on the conversion plate through a bolt; a position measurer is mounted and fixed on a measurer mounting base; the measurer mounting base is fixed in two or more different directions of the V-shaped support; suckers are mounted on sucker support legs; the sucker support legs are connected with sucker fixed blocks; the sucker fixed blocks are mounted on the conversion plate; the suckers are mounted around the V-shaped support; and the suckers are perpendicular to a sucker bonding surface of the machined equipment. The machining device is matched with related machining tool, and realizes precise positioning and fixing functions for the machined equipment under high-radioactivity environment underwater through remote operation.
Description
technical field [0001] The invention belongs to the technical field of underwater positioning of nuclear power plants, and in particular relates to a processing device which can be used for underwater processing and has the function of repeated and precise positioning. Background technique [0002] After the nuclear power plant has been in operation for a long time, the aging equipment such as the internal components of the reactor will have defects locally, and the reliability will be reduced. At this time, these equipment need to be overhauled. For some processes that have high positioning requirements for processing positions and can only be completed by underwater remote operations, and considering the maintenance period and cost, it is necessary to avoid designing, processing and using large positioning devices as much as possible. In the field remote operation work, it is necessary to perform various processes on the processed object, and at the same time, the processe...
