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 [0001] The invention relates to an electroplating tooling, in particular to a partial electroplating device for a buffer shaft of a drive mechanism of a nuclear reactor control rod. Background technique [0002] The surface treatment of the buffer shaft includes hard chrome plating on small holes, hard chrome plating on the inner circle, and hard chrome plating on the outer circle. It belongs to partial electroplating and has very strict requirements on the control of the electroplating process. Very high requirements. After plating, the surface of the coating must be ground, and then PT non-destructive testing should be performed after grinding, which has high requirements for the compactness of the coating. However, in the traditional process, the protection of local electroplating is not in place, and there are defects such as plating overflow. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the in...
