Hollow part electroplating device

Abstract

The invention discloses a hollow part electroplating device which belongs to the technical field of electroplating. The device comprises an electroplating slot, an anode assembly and a cathode assembly, wherein a plurality of anode rods which are arranged side by side are arranged above the electroplating slot; a cathode anode is arranged between adjacent two anode rods above the electroplating slot; the cathode assembly is used for placing a hollow part; the anode assembly is detachably connected to the cathode assembly and is positioned at the inner side of the cathode assembly; the anode assembly and the cathode assembly are kept insulated; the cathode assembly is electrically connected to the cathode rods; and the anode assembly is electrically connected to the anode rods. In an electroplating process, the anode rods are mounted inside the hollow part, and anode plates are mounted outside the hollow part, so that inner and outer surfaces of the hollow part are good in electroplating effect and are high in electroplating efficiency. The hollow part is supported by a hanger, so that the hollow part can be effectively limited, placed and taken, and thus, electroplating efficiencyis favorably improved.

Description

technical field [0001] The invention relates to an electroplating device for hollow parts, belonging to the technical field of electroplating. Background technique [0002] At present, in the electroplating of parts, some parts are cavity parts. Using the traditional electroplating method, because the inner surface of the cavity of the part needs to be electroplated, it needs to absorb the metal ions in the electroplating bath, and the flow speed of the electroplating bath is difficult to reach the level of electroplating. The speed required results in poor plating on the inner surface of the cavity of the part. [0003] The Chinese patent document with the publication number CN202830208U discloses a jig for electroplating copper on the inner surface of bearing rings. During the production process of electroplating copper, the bearing rings are stacked one by one in the sleeve, and the end faces with the same width need to be opposite to each other. Stacking: If the big end...

Problems solved by technology

[0004] However, before electroplating, it is necessary to stack the bearing rings one by one in the sleeve, then install the sleeve on the gland, insert the electrode rod into the sleeve, and finally place the fixture in the copper electroplating solution tank to start electroplating , After the electroplating is completed, the above steps are reversely completed to remove the bearing ring from the sleeve, and the electroplating efficiency is low

In addition, the bearing ring is not effectively limited. For example, if the outer circle of the bearing ring is positioned through the sleeve, since the outer circle of the bearing ring is in contact with the inner wall of the sleeve, there will be an inner and outer circular surface of the bearing ring. The problem that electroplating cannot be performed at the same time; if the outer diameter of the bearing ring is smaller than the inner diameter of the sleeve, the bearing ring will be dislocated due to the lack of effective limit, and the inner circular surface of some bearing rings will contact the electrode rod, giving the inner The quality of round surface plating is badly affected
