Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipes, in particular to a novel exhaust pipe bracket. Background Art

[0002] Lightweighting of aircraft has been a development trend in the aircraft industry. The wall thickness of the exhaust manifold involved in the present invention is only 0.8mm, so it is crucial for the bracket welded on the exhaust manifold to serve as a fixed support structure to have a reasonable structure. The original bracket is welded on the manifold with three-sided welds, so the welds are not closed and are very likely to crack at the sharp parts of the starting or ending points of the welds. In addition, the original bracket is designed as two "L" structures, which need to be welded twice. The two weldings will cause the exhaust pipe area between the two brackets to be repeatedly and unevenly heated, resulting in welding defects. At the same time, the angle of the "L" is very easy to deform during use, affecting the use effect. Therefore, a new type of exhaust pipe bracket is needed to overcome the occurrence of the above problems. Utility Model Content

[0003] In order to solve the above problems, the present invention provides an exhaust manifold bracket with a new structure. To solve the above technical problems, the technical solution adopted by the present invention is:

[0004] A thin-walled exhaust manifold bracket includes an arc-shaped bracket and a U-shaped bracket. The end of the arc-shaped bracket is provided with a U-shaped mounting hole for adjusting the distance. The arc-shaped edge of the arc-shaped bracket and the U-shaped bracket are uniformly provided with edge ribs to improve the rigidity and strength of the bracket.

[0005] Furthermore, the structures of the arc-shaped bracket and the U-shaped bracket are contoured structures.

[0006] Furthermore, the arc-shaped bracket is stamped in one piece.

[0007] Furthermore, a contoured structural base is provided under the U-shaped bracket, and a mounting hole for connecting to the exhaust pipe is provided on the base.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] 1. The curved bracket 1 was modified from two independent brackets into a single integrated bracket. Ribs were added around the bracket to improve its rigidity and strength. The bracket's contoured structure was welded all around, avoiding repeated uneven heating of the exhaust pipe area between the two brackets, which could cause welding defects. This also prevented sharp weld toes from forming on the unwelded surface of the original bracket, which could cause exhaust manifold tearing.

[0010] 2. The U-shaped bracket 2 changes the installation position from above the exhaust pipe to below, and the exhaust pipe is changed from hoisting to supporting. At the same time, the contact part between the bracket and the exhaust manifold is changed to a contoured structure to increase the contact area with the exhaust manifold, so that the bracket supports the exhaust pipe like two hands, thereby improving the supporting strength of the exhaust manifold. This bracket changes the structure from "L" type to "U" type, and the force on the bracket is changed from tension to pressure perpendicular to the "U" section. The stability of the bracket is significantly improved to ensure the accuracy of the bracket mounting hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0019] Example 1: See Figure 1-3The embodiment of the present invention provides a novel exhaust manifold bracket structure, comprising an arc-shaped bracket 1 and a U-shaped bracket 2 fixed to the exhaust pipe. The end of the arc-shaped bracket 1 is provided with a U-shaped mounting hole 4 for adjusting the distance, which is used to connect to the exhaust pipe. The arc-shaped edge of the arc-shaped bracket 1 and the U-shaped bracket 2 are uniformly provided with edge ribs 3, which can effectively improve the rigidity and strength of the bracket. The arc-shaped bracket 1 adopts a contoured structure and can be directly welded all around, avoiding repeated uneven heating of the exhaust pipe area between the two brackets due to two weldings, thereby causing welding defects. At the same time, it also avoids the formation of sharp weld toes on the unwelded surface of the original bracket, which may cause exhaust manifold tearing.

[0020] A base 6 is provided under the U-shaped bracket 2, and a mounting hole 5 for connecting to the exhaust pipe is provided on the base 6 for fixing to the exhaust pipe. The stability of the bracket is significantly improved to ensure the accuracy of the bracket mounting hole.

[0021] Beneficial effects:

[0022] 1. The arc-shaped edge of the arc-shaped bracket 1 and the upper part of the U-shaped bracket 2 are formed with edge ribs 3, which can improve the rigidity and strength of the bracket, while increasing the contact area with the exhaust pipe and improving the supporting strength of the bracket.

[0023] 2. The bionic structure adopted by the arc-shaped bracket 1 can be directly welded all around, avoiding repeated uneven heating of the exhaust pipe area between the two brackets due to two weldings, thereby causing welding defects, and at the same time avoiding the formation of sharp weld toes on the unwelded surface of the original bracket, which may cause the exhaust manifold to tear.

[0024] 3. Bracket 2 is changed from L-shape to U-shape, and the force on the bracket is changed from tension to pressure perpendicular to the "U" section. The stability of the bracket is significantly improved to ensure the accuracy of the bracket installation hole.

[0025] Example 2 is a further improvement based on Example 1, in which the arc-shaped bracket 1 and the U-shaped bracket 2 are an integrated contour-matching structure.
