Abstract
The invention discloses a selective electroplating device of a formation sleeve shaft of a reactor control rod drive mechanism. The selective electroplating device is characterized by comprising a formation sleeve shaft body, wherein a plastic pipe is sleeved on a non-electroplating part of the formation sleeve shaft body, the plastic pipe and the formation sleeve shaft body are fixed through a fixing member, a plating-resisting rubber belt is arranged on the surface of the plastic pipe, a solid pipe tightly matched with the formation sleeve shaft body is arranged inside the formation sleeve shaft body, and the bottom of the solid pipe is connected with a base. The invention has the advantages that the bottom of the solid pipe is connected with the base, and a gasket is arranged between the base and the formation sleeve shaft body, so that collision can be prevented, and a threaded plating of the formation sleeve shaft body is protected. The plastic pipe is sleeved outside the non-electroplating part of the formation sleeve shaft body, and the plating-resisting rubber belt is arranged on the surface of the plastic pipe, thus the defects of poor selective electroplating protection, plating overflowing and the like in the traditional process are avoided, and the threaded plating is uniform and compact.
Description
Technical field
The present invention relates to command bundle rods for nuclear reactors driving mechanism and form quill local electroplating device.
Background technology
The process of stroke sleeve surface needs to electroplate screw thread, and plating is hard chrome, and thickness is 12um-20um, belongs to parcel plating, very strict to electroplating technology control overflow.Stroke sleeve pipe overall length has 4 meters, weighs 1.5 tons, and the screw thread at plating position is nonstandard screw thread, and screw thread all has go-no go gauge requirement before plating with after plating, and plating difficulty is very high.How to carry out the protection of non-electrical surfacing and how to determine that the electroplating technology of flat of thread is very large difficult point.Therefore, a kind of technical scheme should be provided to solve the problem.
Summary of the invention
The object of the invention is: provide a kind of command bundle rods for nuclear reactors driving mechanism to form quill local electroplating device.
For achieving the above object, the technical solution used in the present invention is:
Command bundle rods for nuclear reactors driving mechanism forms quill local electroplating device, comprise and form quill axis body, the outside forming the non-electroplating part of quill axis body is arranged with plastics tubing, fixed by mounting block between described plastics tubing and formation quill axis body, the surface of described plastics tubing is provided with resistance plating adhesive tape, the inside of described formation quill axis body is provided with and forms the close-fitting solid tubes of quill axis body, the bottom of described solid tubes is connected with base, is provided with pad between described base and formation quill axis body.
Described mounting block comprises the vertical bolt through whole stroke quill axis body inside.
Described mounting block also comprises the steel ring be located between plastics tubing and the plating position forming quill axis body.
The material of described solid tubes and base is stainless steel.
The material of described pad is pure lead.
Advantage of the present invention is: the bottom of solid tubes is connected with base, and be provided with pad between base and formation quill axis body, such assembling mode can prevent from colliding with, and protection forms the screw thread coating of quill axis body.Adopt and be arranged with plastics tubing in the outside of the non-electroplating part forming quill axis body, the surface of plastics tubing is provided with resistance plating adhesive tape, adopts this kind of local resistance plating mode; avoid in traditional technology not in place to parcel plating protection; the defects such as coating spilling, ensure that product screw thread coating is even, fine and close.Accompanying drawing explanation
