The invention relates to electroplating of parts, in particular, equipment for coating a part of a complex configuration with deep and blind holes.

The purpose of the invention is to increase labor productivity,

Figure 1 schematically shows a General view of the device; FIG. 2 is a section A-A in FIG. one .

The device dp of galvanic machining of parts contains a current-carrying rod 1 connected to the electric drive 2. The cathode elements 3 are made in the form of hooks for accommodating parts 4 welded to disks 5 fixed on the current-carrying rod 1 on an equal footing distance from each other, the holder 6, which protects the parts from falling off the hook. The current from the power source is supplied to the supply prism 7.

The device works as follows.

. Parts 4 are hung on hooks 3 and covered with holder 6, then transported by vehicles over process baths (not shown. When the device is immersed in the electrolyte from the power source, it is fed to the current carrying prism 7, which through the rod 1 and disks 5 with hooks 3 goes to the parts to be machined. 4. When the rod rotates by means of an electric drive 2, the parts move around the circumference, make a reciprocating motion along the pin of the hook due to the gap

between the hook 3 and the holder 6 and rotate around its axis due to the displacement of the center of gravity of the part 4, thereby ensuring a good exchange of electrolyte in deep and blind holes, accelerating the electrodeposition of the metal on the surface of the parts, obtaining a quality uniform coating.

The number of disks and hooks is selected based on the dimensions of the part, the calculated current strength and the contact area.

All metal parts found in the electrolyte, with the exception of the hook, are insulated.

The removal of the coating from the hook occurs in a special bath built into the automatic line. I

The proposed device allows to obtain a uniform coating of parts with a complex configuration with blind and through holes, prevent deformations on the surface of parts, and increase productivity.
