Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing a damaged portion of a composite component for repairing a small-scale damage generated in the composite component.

[0002]

2. Description of the Related Art Composite materials are used in a wide range of fields from aircraft parts to vehicles and containers.
Although the composite material has sufficient strength and rigidity of the whole part, its surface and the like are relatively easily damaged. When such damage occurs, a method for repairing a composite material article having a damaged portion is to first remove the periphery of the damaged portion by machining or the like, and then bury a resin or adhere a patch or a core plug. And the like. In any case, it is necessary to first remove the damaged portion by machining or the like. In this case, the processing differs depending on the degree and size of the damage. FIG. 12 shows an example of these processing modes and restoration. In FIG. 12A, when the surface portion of the solid panel is damaged, the solid panel is processed into a shallow bowl shape, an oval shape in plan view, or the like according to the depth of the damage.
This restoration fills and buries the resin material. FIG. 12 (B) shows a case where damage is found in the internal space of the solid panel, in which perforation removal or taper removal is performed depending on the degree of damage. These restorations are performed by filling with a resin material, bonding with a patch, or the like. FIG. 12C shows an example in which the composite material has a relatively shallow flaw in the honeycomb panel, and a perforation process that does not penetrate the panel is performed, and a core plug or a patch is bonded.

[0003] As a prior art which discloses a method of repairing such a damaged composite material, Japanese Patent Application Laid-Open No. 50199/1990 has been proposed.
No. 8 is found. According to this example, a pre-cured composite or metal repair patch is adhered to the damaged part by bonding, or the damaged part is removed and heat and pressure are applied to rebuild it in the same way as the original part was made However, any means such as mechanical grinding with a hand or a suitable tool, a portable sanding tool, etc. are only possible, and no specific structural apparatus is shown. This prior art is directed to obtaining an adhesive or binder resin composition that is curable at low temperatures and has sufficient thermal properties, cure strength and water resistance to be suitable for repairing damaged composites. Because it is.

As a prior art of a tool for repairing a flat portion, there is Japanese Patent Application Laid-Open No. Hei 5-337429. This is a tool for repairing defective painted parts of the top coat applied in the painting process of the car body.It has a disc-shaped grinding blade and a grinding holder that has a regulating part that slides on the painted surface and holds the grinding blade. Therefore, it is difficult to adapt to various kinds of machining as described above when repairing a damaged portion of a composite material, and is significantly different from the present invention described below. This is not intended for composite materials.

[0005]

As described above, in machining for removing a damaged portion, machining with a manual tool requires not only skill but also various problems. In other words, in the case of removing the surface layer, the dimensional accuracy is difficult to be obtained because the processing depth is small. In the processing of the tapered shape, a dedicated blade must be prepared according to the size of the damaged portion, which increases costs and man-hours. Even if an umbrella-shaped tool that fits the appropriate taper shape is used, a sufficient peripheral speed can be obtained because the umbrella-shaped tip, that is, the cutting edge of the blade tip is close to the center of rotation, from the physical shape of the umbrella. There was a problem in the cutting properties. Furthermore, since the blade rotation axis is perpendicular to the processing surface, the distance from the edge of the cutting edge to the tool rotation center is different from the distance from the cutter bottom to the tool rotation center. There is a problem in that the cut surface does not have a smooth finish and the quality of the repair / repair work performed after removing the damaged portion is adversely affected. In addition, such machining generally involves cutting most of the time at the tip of the blade, so that the life of the blade is short, and this tends to increase the cost.

[0006] The optimal mechanical device for repairing and repairing such a damaged composite article could not be found heretofore. The present invention has been made in view of the above problems, and in a machining device for removing a damaged portion of a composite material component, any of machining processes such as surface layer removal, perforated portion removal, and tapering depending on the degree of damage. An object of the present invention is to provide a device for removing a damaged portion of a composite component, which is capable of improving a cutting efficiency and a life of a cutting tool, has no unevenness on a cutting surface, and can obtain a good cutting surface.

The spindle 8 is adjusted in the cutting direction and fixed by the spindle fixing mechanism B (FIG. 4). The blade 22 having a large diameter and a short blade length is selected and attached. Next, while cutting, the cutting surface of the blade is lowered from the surface of the component to the processing depth by the handle H, and then the rail 16 is changed by the handle K of the tilt angle adjusting mechanism C to process the damaged portion into an R shape ( See FIG. 11).

The inclination of the rail 16 is adjusted by the handle K so that the taper angle to be cut is obtained (inclination angle adjustment mechanism C). The handle H is used to adjust the position of the blade tip to the taper start position on the panel surface of the composite component. Thereafter, the height of the blade with respect to the panel surface is not changed, and the side surface of the end mill is used, and the rail 16 is used.
The cutter is moved to the center by the cutter device position adjusting mechanism D along the axis and the main shaft 8 is turned to cut the tapered shape.

[0030]

As described above, according to the present invention, various types of mechanical processing such as removal of a surface layer, drilling, and tapering can be easily performed according to various types of damage to a composite component. Since it can be performed with high accuracy, it can contribute to quality improvement of repair / repair parts.

By continuously changing the rotation axis of the blade by adjusting the handle of the inclination adjusting mechanism, it is possible to remove a particularly shallow surface layer.

Since the rotation axis of the blade can be set at two positions parallel or perpendicular to the rail, various cutting processes using the bottom surface of the blade and the side surfaces of the blade can be performed. Therefore, the peripheral speed of the blade does not change even at the center of rotation of the blade, a smooth cut surface without irregularities can be obtained, and good cutting properties and a long life of the blade can be achieved.
