Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an auxiliary device used when separately painting a workpiece having a curved surface such as a cowling for a motorcycle.

(Prior art) In order to paint different colors on a motorcycle cowling, as shown in Figure 3, the main color A is first painted on the entire surface of the cowling w, and then the surface of the cowling w is painted with the main color A. I applied masking a for color separation, and then painted the color apertures over the entire surface, but with this alone, when I painted the main color A and the color apertures on the front side, the scattered mist could spread to the back side. Because it adheres to the surface and makes the appearance unsightly, it is necessary to mask the area around the back side of the cowling w, apply black paint to the entire back side, and finally remove the masking b from around the back side. It was.

For this reason, this type of painting not only requires a lot of work such as applying and removing masking, but also has disadvantages such as having to apply unnecessary black paint.

(Purpose) The present invention was created in view of these inconveniences, and the purpose is to provide a simple auxiliary device for separate painting that can eliminate the labor of masking and unnecessary painting processes. be.

(Means for Achieving the Object) That is, the present invention is an auxiliary device for separate painting to achieve the above object, which has a surface that follows the curved shape of the workpiece w to be painted in order to hold it in close contact with the workpiece w. In addition, the jig body 1 is provided with a guiding cylinder 3 for discharging the paint to the back side corresponding to the position of the window hole h of the workpiece w, and a curved surface shape of the workpiece w is attached to the jig body 1 to airtightly cover the unpainted base portion. A cover member 6 having a back surface that conforms to the cover member and having an elastic band-like body 8 on its peripheral edge is removably attached.

(Example) The details of the present invention will be explained below based on the illustrated example.

The drawing shows one embodiment of the present invention, and the jig body 1 is made of FRP and has a SP material core formed to match the outer shape and curved shape of the cowling w to be painted. Hole h, h (Fig. 4)
Cylindrical bodies 3, 3 as shown in FIG. 2 are integrally formed in the portions 2, 2 where the cowling w is located, facing toward the back side of the cowling w.

This jig main body 1 is fixed on a support stand 4 to ensure a certain height for convenience of work.
Further, a cover 6 is attached to the upper edge of the jig main body 1 so as to be openable and closable by a hinge 7, which opens the portion 5 to be painted separately and covers the other portions. This cover 6, like the jig main body 1, is formed to match the curved shape of a part of the cowling w,
Further, an elastic band-like body 8 such as a sponge is integrally attached to the periphery of the back surface to prevent paint mist of different colors from entering the covered portion.

Note that the reference numeral 9 in the figure indicates a clamp member of the cover 6 provided at the lower edge of the jig main body 1.

In the apparatus configured as described above, first, the cover 6 is opened and the cowling w to be painted is placed in close contact with the surface of the jig main body 1, and in this state, the main color is applied to the entire surface of the cowling w. By the way, the paint mist scatters during this painting, but since the periphery of the cowling w is in close contact with the surface of the jig body 1,
The mist does not adhere to the back side of the cowling w. In addition, the parts 2, 2 of the jig main body 1 where the window holes h, h of the cowling w are located are formed with cylinders 3, 3 protruding toward the back side, so as in this example, the cowling w Even if there are two window holes h, h, when painting one window hole h, the paint that escapes to the back side through the cylinder 3 will be transferred to the other cylinder 3.
The paint will not flow back onto the surface of the cowling w again due to being blocked by the paint, and therefore will not cause paint stains on the periphery of the window hole h.

After painting the main body color, the cover 6 is turned over and clamped onto the cowling w, and the entire surface is painted with a different color from above. As a result, the color-coded portions of the cowling w are protected by the elastic band 8 provided on the back surface of the cover 6 and can be neatly painted.

In the above-mentioned embodiment, the cover 6 is attached to the jig body 1 with a hinge 7 so that it can be opened and closed. It is also possible to configure the cover 6 to be attached.

(Effects) As described above, according to the present invention, the cover member that covers the underlying portion to be left is removably attached to the jig body formed to match the curved shape of the workpiece, so that it can be attached for masking, Different coatings can be easily applied by simply attaching and detaching the cover member without requiring a peeling process. In addition, by tightly holding the workpiece between the jig body and the cover member that match the curved surface of the workpiece, distortions during forming can be corrected, and at the same time, distortions of the workpiece that may occur during painting can be avoided. Further, there is no room for paint mist to enter the gap between the workpiece and the jig body or the cover member and the workpiece, so that only the surfaces to be painted can be reliably coated.

In addition, since a guide tube for discharging paint is provided in the part of the jig body that corresponds to the window hole of the workpiece, even if the workpiece has multiple windows, this guide tube can be used when painting one window hole. This guiding cylinder can prevent the paint that has come out from the back side of the workpiece through the cylinder from flowing back onto the surface of the workpiece from the other window hole, and the paint that flows back can prevent the paint from flowing back onto the workpiece surface. It is possible to prevent stains from forming on the surface.
