Abstract

A crank-pin anode holder (1) for the electro-plating industry follows the movement of a crank-pin to be plated which is rotating horizontally. During operation, non-metallic shoes (12) of a jaw plate (4) centralize themselves and sit on the crank-pin inside a plating solution. As the ends of the non-metallic shoes (12) are situated away from the jaw plates (4), it can prevent the holder (1) from contacting with the thrust produced and remove studs formed during the plating process. Anodes (2) with anode bags (11) are placed in both sides of the jaw plate (4) and each extend to an anode seat (5). Two parallel channel chacks (3) can slide up and down with a preset button die therebetween mounted on a metal bar above the solution for electro-plating. A handle (7) is welded on the upper part of the right-hand channel chack (3) for use by the operator in carrying and setting. In the middle, there is a current copper bar (8), insulated from the channel chacks (3) by non-metallic bushes (9), and electrically connected with the two anodes (2). A cable (10) passes current from a bus bar to the copper bar (8) and thence to the anodes (2).
