Problems solved by technology

[0005] However, when using the plating apparatus in which the electrodes are fixed as disclosed in Patent Document 1, the cylinder inner peripheral surface and the electrodes may come into contact with each other in attaching or detaching the cylinder block, thereby damaging the cylinder inner peripheral surface.
In particular, damage to the inner peripheral surface of the cylinder after the pre-plating process can cause defects such as plating adhesion and uneven plating film thickness
Therefore, the operator needs to carefully attach and detach the cylinder block, which leads to a decrease in operating efficiency

[0102] [The second embodiment ( Figure 11 )]

[0103] Figure 11 With Figure 8 Correspondingly, a schematic side view of the main part of the second embodiment of the electroplating apparatus according to the present invention is shown. In the second embodiment, parts similar to those of the first embodiment are identified by the same reference numerals, and descriptions thereof are simplified or omitted.

[0104] The electroplating apparatus 60 of the second embodiment is different from the electroplating apparatus 10 in the first embodiment in that the insertion guide 61 includes a prism portion 62, a cylindrical portion 63 integrally provided at the top end of the prism portion 62, and a tapered portion 64. and 65 , tapered portions 64 and 65 tapered toward their respective pointed ends, are formed on the top ends of the prismatic portion 62 and the cylindrical portion 63, respectively.

[0105] The taper angle of the tapered portion 64 at the top end of the prism por...

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 ...
