Abstract
The invention discloses a local electroplating device for a buffer shaft of a driving mechanism of a control rod of a nuclear reactor. The local electroplating device comprises the buffer shaft. The lower portion of the buffer shaft is fixed onto a pressure plate, the pressure plate is downwardly connected with a bearing plate, the upper portion of the pressure plate is connected with a conductive device, the conductive device is inserted in the buffer shaft and comprises a conductive stainless steel support pillar and a stainless steel solid tube, external windows of the buffer shaft are closed by stop pieces, barriers prevent external small holes of the buffer shaft from being electroplated, a plastic mold prevents a middle portion, which is not required to be electroplated, of the buffer shaft from being electroplated, and the stop pieces and the barriers are fixed by threaded fasteners and a plastic ring. The local electroplating device has the advantages that shortcomings of incomplete protection for local electroplating, overflow of electroplated coatings and the like of the traditional process are overcome, and the local electroplating device guarantees that electroplated coatings are formed on various electroplated portions of a product and are uniform and compact.
Description
Technical field
The present invention relates to a kind of electroplating tooling, relate in particular to a kind of command bundle rods for nuclear reactors driving mechanism buffer shaft local electroplating device.
Background technology
The buffer shaft surface treatment comprises the aperture hard chrome plating, the inner circle hard chrome plating, the cylindrical hard chrome plating belongs to parcel plating, and control requires very strict to electroplating technology, the chromium layer thickness is between 100um-120um, coating uniformity there is very high requirement, after having plated, carries out the coating surface grinding, carry out again the PT non-destructive test(ing)(NDT) after the grinding, the compactness of coating is had very high requirement.And not in place to the parcel plating protection in the traditional technology, there are the defectives such as coating overflows.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
