Description

Technical Field

[0001] The utility model relates to the technical field of rubber pad cutting, in particular to a cutting tool. Background Art

[0002] The main body of the lampshade at the wing tip and wing root of the aircraft is glass, and there is a circle of rubber pads on the outer circle of the lampshade, and the outermost rubber pad is about 5mm higher than the surface of the lampshade. After the lampshade at the wing tip and wing root of the aircraft is installed, the lampshade and the skin are adjacently spliced, the surface of the lampshade and the skin are basically flush, the rubber pad is located between the lampshade and the skin, and the rubber pad protruding from the surface of the lampshade on the outer periphery of the lampshade also protrudes from the surface of the skin. According to production requirements, the part of the rubber pad on the outer circle of the lampshade protruding from the skin and the lampshade surface must be cut off.

[0003] Since the lampshade is installed on the outer surface of the aircraft wing, it has a great impact on the startup and appearance, and requires high flatness and uniformity after the rubber is cut. The traditional cutting method is that the operator directly holds a utility knife and uses the blade to cut the protruding skin and the rubber on the lampshade surface. The traditional operation method has the following shortcomings:

[0004] 1. When cutting with a handheld utility knife, the cutting thickness is controlled manually, which is very difficult to control. A slight deviation will cause the thickness of the cut rubber pad to be inconsistent in different places.

[0005] 2. As the rubber pad has a low hardness, it must be shaped in one go when the blade is cutting. If the amount of cutting in one go is insufficient and there is still a small part of the rubber pad protruding from the surface of the skin and the lampshade, it will be difficult to cut again based on what has already been cut.

[0006] 3. Half of the outermost rubber pad is on the lampshade, and the other half is on the outside of the glass lampshade. If the cutting amount is too large, the blade will scratch the edge of the glass lampshade and cause damage. Utility Model Content

[0038] like Figures 1 to 3 As shown, this embodiment provides a cutting tool, the outermost circle of the aircraft lampshade has a rubber pad higher than the lampshade, after the aircraft lampshade is installed, the lampshade surface and the skin are basically flush, and the cutting tool is used to cut the rubber pad protruding from the skin surface and the lampshade surface between the skin and the lampshade.

[0039] In some embodiments, the cutting tool includes a mounting part 1 and a cutting part 2, the mounting part 1 includes a first abutting portion 11, a second abutting portion 12 and a placing portion 13, the first abutting portion 11 and the second abutting portion 12 are arranged at intervals and respectively form contact planes, the placing portion 13 is arranged between the first abutting portion 11 and the second abutting portion 12, and has a discharge groove 4; the first abutting portion 11 and the second abutting portion 12 are both used to abut the skin and the lampshade; the cutting part 2 is arranged on the placing portion 13, the cutting part 2 covers the discharge groove 4, and at least the cutting blade of the cutting part 2 is located above the contact plane.

[0040] The first abutting portion 11 and the second abutting portion 12 can abut against the skin and the lampshade, and are not directly cut by a manual utility knife, so that the cutting piece 2 will not scratch the skin and the lampshade. And when in use, the first abutting portion 11 and the second abutting portion 12 are respectively formed with contact planes, so that when cutting, the mounting member 1 can slide on the skin and the lampshade along the setting direction of the rubber pad, thereby achieving one-time cutting and forming; at least the cutting blade of the cutting member 2 is located above the contact plane, so that the cutting member 2 can easily cut off the protruding rubber pad. The tooling structure is simple and easy for operators to operate. During the cutting process, the position of the cutting member 2 set on the mounting member 1 does not need to be changed, and the distance between the cutting member 2 and the surface of the lampshade is fixed, so that the thickness of the rubber pad after cutting is consistent at all places.

[0041] Specifically, in this embodiment, the placement portion 13 is inclined along a direction perpendicular to the first direction X toward a side away from the first abutting portion 11 and the second abutting portion 12. In order to facilitate cutting off the protruding rubber pad, the inclination angle α of the placement portion 13 is 6°-10°. The material of the mounting member 1 is resin, which has flexibility. When the mounting member 1 slides on the surface of the skin and the lampshade, it will not scratch the skin of the lampshade, which plays a role in protecting the skin and the lampshade; and the resin material is transparent, and the contact between the cutting member 2 and the rubber pad can be intuitively seen during cutting, which is conducive to improving the cutting yield.

[0042] The first abutting portion 11 includes a first abutting surface 111 and a second abutting surface 112, and the second abutting portion 12 includes a third abutting surface 121 and a fourth abutting surface 122. The first abutting surface 111 and the third abutting surface 121 are both used to abut the skin, and the second abutting surface 112 and the fourth abutting surface 122 are both used to abut the lampshade. Since the placement portion 13 is arranged at an angle, in order for the first placement portion 132 and the second placement portion 133 to be located at the same horizontal height when in use, the second abutting portion 12 is arranged to protrude from the placement portion 13.

[0043] In order to facilitate the discharge of excess waste during the cutting process, the mounting member 1 is provided with a discharge chute 4, which passes through the two side surfaces of the mounting member 1 along the first direction X. The placement portion 13 includes a first placement portion 132 and a second placement portion 133, and a discharge chute 4 is formed between the first placement portion 132 and the second placement portion 133. The discharge chute 4 is used to discharge the waste rubber pad after cutting. Specifically, according to the width of the rubber pad and the height of the rubber pad protruding from the skin surface and the lampshade surface, the width of the discharge chute 4 is 9mm-11mm, and the depth of the discharge chute 4 is 6mm-8mm.

[0044] Specifically, the first abutment portion 11 is divided into two parts by the discharge chute 4, and the first abutment surface 111 and the second abutment surface 112 are respectively located at two parts of the discharge chute 4; the second abutment surface 112 is divided into two parts by the discharge chute 4, and the second abutment surface 112 and the third abutment surface 121 are respectively located on both sides of the discharge chute 4.
