As shown in the figure, the metal surface repairing instrument according to the present embodiment includes each configuration of a grip portion 10, an electrode head 20, an electrolytic solution impregnating member 30, and an electrode head support member 40.

The grip portion 10 is a portion for a worker to grip and operate a metal surface repairing instrument (hereinafter, also abbreviated as “the instrument”) according to the present embodiment during repair work, and is electrically operated. It is made of an insulating material (eg, wood, synthetic resin, synthetic rubber).

The electrode head 20 is made of a conductive metal material. The electrode head 20 is a main part for forming a plating film on the surface of a metal product by the principle of electroplating or electroplating. Therefore, the electrode head 20 may be formed of, for example, a metal material capable of effectively electroforming or electroplating depending on the metal material of the plating film formed on the surface of the metal product to be treated. preferable.
Further, it is preferable that the electrode head 20 is formed in a shape that can correspond to the shape of the surface to be treated of the assumed metal product and the condition of the repaired portion on the surface to be treated. For example, since it is desired to keep the distance between the electrode head 20 and the surface to be processed of the metal product uniform during the processing, it is possible to form the surface of the electrode head 20 in a shape corresponding to the shape of the surface to be processed. preferable. However, the present invention is not limited to this.

The electrolytic solution impregnating member 30 is attached to the electrode head 20 so as to wrap the surface of the electrode head 20. The electrolytic solution impregnating member 30 is used by impregnating an electrolytic solution containing metal ions used for plating during repair work. That is, by bringing the electrolytic solution impregnated member 30 into contact with the surface to be treated of the metal material, a layer of the electrolytic solution impregnated in the member is formed between the electrode head 20 and the surface to be treated of the metal material. To. This makes it possible to form a plating film on the surface to be treated of a metal material by the principle of electroforming or electroplating without immersing the metal product in a large electrolytic solution tank.
The electrolytic solution impregnating member 30 is preferably made of a material (for example, cotton cloth or sponge) capable of impregnating the electrolytic solution.

In the present embodiment, as shown in FIGS. 1A and 1B, the electrode head 20 is fitted into the rod-shaped electrode head support member 40 and integrated. Then, a connected portion 41 is formed at the base end portion of the electrode head support member 40. On the other hand, a connecting portion 11 is formed at the tip of the grip portion 10, and the connected portion 41 of the electrode head support member 40 is rotatably connected to the connecting portion 11.
The connected portion 41 and the connecting portion 11 thus connected form an angle-adjusting rotating portion that rotatably connects the electrode head 20 to the grip portion 10. That is, the connecting portion 11 and the connected portion 41 are fastened by fasteners 50 such as bolts and nuts. Then, by loosening the fastener 50, the fastener 50 can be used as a support shaft to rotate between the fasteners 50. By this rotation operation, the electrode head 20 can be tilted at an arbitrary angle with respect to the grip portion 10, and the electrode head 20 can be adjusted to a suitable arrangement with respect to the surface to be processed of the metal product.

For example, as shown in FIGS. 2A to 2C, the inclination angle of the electrode head 20 with respect to the grip portion 10 is adjusted according to the position of the repaired portion 1a on the surface 1A to be processed of the metal product 1. The worker can operate the instrument by gripping the grip portion 10 in a constant posture that is easy to operate.

In this state, the electrode head 20 is brought close to the repaired portion 1a on the surface to be processed 1A of the metal product 1, and the electrolytic solution impregnating member 30 is in contact with the surface to be processed 1A.

While maintaining this state, the operation of rubbing the electrode head 20 and the electrolytic solution impregnating member 30 against the surface to be processed 1A of the metal product 1 is repeated (see FIG. 5A). By repeating this operation, the plating film is formed in multiple layers on the repaired portion 1a (for example, the portion where wear or dent is generated) on the surface 1A to be processed of the metal product 1 by the principle of electrocasting or electroplating. Then, the repaired portion 1a is overlaid (see FIG. 5B). Then, the overlay 2 is polished using the polishing tool 70 to finish the repaired portion 1a according to the surrounding surface to be processed 1A (see FIG. 5C).
With such a procedure, the surface to be processed 1A of the metal product 1 can be easily repaired.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications and applications can be implemented as needed.

Further, as shown in FIG. 6, the electrode head 20 can be detachably attached to the electrode head support member 40. With this configuration, the electrode head 20 can be replaced more easily without removing the fastener 50. Specifically, the rod-shaped portion of the electrode head support member 40 constitutes the electrode head mounting portion 42, and the fitting recess 21 is formed along the central axis from the proximal end surface of the electrode head 20 toward the inside. The electrode head 20 is mounted on the electrode head support member 40 by fitting the fitting recess 21 into the electrode head mounting portion 42. On the other hand, the electrode head 20 is removed from the electrode head support member 40 by pulling out the electrode head mounting portion 42 from the fitting recess 21.
