CYLINDER PLATING EQUIPMENT

Japanese Patent JP3276044

B2

PURPOSE: To uniformize the plated film thickness and the hardness, and to improve the working efficiency by setting a cylinder loading surface of a plating jig lower table in the horizontal direction, and projectingly forming an electrode supporting table in the direction of the cylinder in plating cylinder holes of a V type engine.
CONSTITUTION: When a V type cylinder 14 is loaded on a jig lower table 13 of a plating jig, the loading surface is set horizontal, and an anode electrode 15 and the tip part of a gate set to the tiltation of cylinder holes 14a, 14c are inserted in the cylinder holes 14a, 14c. An anode supporting table 20 of triangular section is arranged on the jig lower table 13, and an electrode supporting part is formed thereon. The cylinder 14 is loaded in a stable condition to obtain the uniform contact with the jig lower table 13, and when the current is applied from a power supply 21, the current flows uniformly, and the plated layer of uniform thickness can be formed. In addition, the row of the cylinder holes 14a can be simultaneously plated with that of the cylinder holes 14c to save the plating time and to reduce the deterioration of the plating solution.
