Abstract

An electroplating apparatus for pre-electroplating or electroplating the inner circumference surface of an air cylinder. In the electroplating apparatus, plane parts are formed on the external wall of the cylinder block on a crankshaft case side of an engine and opposite with each other, a shaft is vertical to the crankshaft case surface and parallel to a cylinder chamber, electrodes are projected from a workpiece mounting platform which contact with the crankshaft case surface of the cylinder block thereon, and a workpiece guide member including an insertion guide piece and an auxiliary guide piece is configured to parallel to a cylindrical electrode on a position of the insertion guide part and the auxiliary guide part facing to the plane parts and stands on the workpiece mounting platform vertically, wherein the insertion guide piece and the auxiliary guide piece are provided with sliding surfaces where the plane parts slide.

Description

technical field

[0001] The present invention relates to a plating apparatus for efficiently pre-plating or electroplating the cylinder inner peripheral surface of a cylinder block in an engine, for example, in which electrodes are opposed to the cylinder inner peripheral surface. Background technique

[0002] Japanese Patent Laid-Open No. 2001-193550 (Patent Document 1) discloses an electroplating apparatus that performs an electroplating process while a treatment liquid flows on a cylinder inner peripheral surface of a cylinder block. The plating apparatus flows the treatment liquid toward the inner peripheral surface of the cylinder as the surface to be treated, and in this case, performs a pre-plating or electroplating process or treatment. Such a plating apparatus has an advantage that a pre-plating or electroplating process can be performed regardless of the size of the cylinder block.

[0003] In addition, the plating apparatus can be easily installed on a production ...
