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, particularly relate to a kind of command bundle rods for nuclear reactors driving mechanism buffer shaft local electroplating device.
Background technology
Buffer shaft surface treatment comprises aperture hard chrome plating, inner circle hard chrome plating, cylindrical hard chrome plating, belongs to parcel plating, very strict to electroplating technology control overflow, layers of chrome thickness is between 100um-120um, there is very high requirement to coating uniformity, after having plated, coating surface grinding be carried out, carry out PT non-destructive test(ing)(NDT) again after grinding, have very high requirement to the compactness of coating.And not in place to parcel plating protection in traditional technology, there is the defects such as coating spilling.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide and a kind ofly ensure that product is respectively electroplated position and all had coating and even, the fine and close command bundle rods for nuclear reactors driving mechanism buffer shaft local electroplating device of coating.
The technical solution used in the present invention is:
Command bundle rods for nuclear reactors driving mechanism buffer shaft local electroplating device, comprise buffer shaft, described buffer shaft bottom is fixed on pressing plate, described pressing plate connects bearing plate downwards, described pressing plate top is connected with electric installation, described electric installation inserts in buffer shaft, described electric installation comprises conduction stainless steel pillar stiffener and stainless steel solid pipe, the window of described buffer shaft outside is closed by block, the aperture of described buffer shaft outside is by baffle plate resistance plating, do not plate part in the middle of described buffer shaft and adopt mould of plastics resistance plating, described block and baffle plate are fixed by threaded fastener and plastic circle ring.
Described pressing plate is stainless steel platen.
Described block is stainless steel block.
Described baffle plate is stainless steel baffle plate.
Beneficial effect of the present invention: buffer shaft is inner to be connected with a stainless steel solid pipe by a conduction stainless steel pillar stiffener; window is adopted to be closed by block; increase plating piece electroconductibility; to change in traditional technology defects such as not in place, the coating spillings of parcel plating protection, ensure that product is respectively electroplated position and all had coating and coating is even, fine and close.
