[0020] The technical solutions of the present application will be described below in conjunction with the embodiments, obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0021] Please refer to Figures 1-3 The aircraft detection component installation error measuring tool shown in the figure, including butt joint seat 1, the top of butt joint seat 1 is connected with measuring body 3 through connecting plate 4, the bottom of connecting plate 4 is connected with the top of butt joint seat 1, the top of one side of connecting plate 4 extends to the outside of the upper part of butt joint seat 1 and is connected with the bottom of measuring body 3.

[0022] ​Specifically, the docking seat 1 is arranged in a rectangular shape, the bottom is arranged horizontally, and a fixing hole 7 is arranged through the thickness direction at each of the four corners of the docking seat 1. The horizontal smooth arrangement facilitates the close contact of the bottom of the docking seat 1 with the mounting surface on the machine body, and can improve the installation accuracy. The fixing hole 7 facilitates the penetration of the bolt, so that the bolt penetrating the fixing hole 7 can be connected with the machine body, thereby fixing the docking seat 1 with the machine body by using the bolt.

[0023] Specifically, the fixing hole 7 is used for the installation of the bolt, and the outer side of the fixing hole 7 is arranged in a 90° countersunk head. The 90° countersunk head fixing bolt is used in cooperation with the fixing hole 7 arranged in a 90° countersunk head on the outer side, which can improve the repeated installation accuracy.

[0024] Specifically, a handle hole is arranged through the middle of the connecting plate 4. The handle hole can facilitate the taking and placing of the entire tooling by the workers, and can also reduce the weight of the connecting plate 4, thereby ensuring the rigidity and reducing the overall weight.

[0025] The connecting plate 4 increases the transverse displacement, thereby ensuring that the measuring body 3 is coaxial with the CCD sensor of the detection component.

After the tooling is installed, the main measurement surface 5 and the secondary measurement surface 6 are at a preset angle with the mounting surface of the detection component on the machine body. Through the measurement of the main measurement surface 5 and the secondary measurement surface 6 by the laser radar, the installation error of the detection component on the machine body can be equivalent obtained through a preset algorithm.

[0027] Specifically, the outer walls of the main measurement surface 5 and the secondary measurement surface 6 are each provided with a layer of reflective coating. The measuring body 3 is made of aluminum material, and the surface is subjected to anodic oxidation treatment. After the treatment, the measuring body 3 is silver-white in color, forming a reflective coating.

When the tooling is used, the protective cover 2 is detached, and when the tooling is not used, the protective cover 2 is sleeved for protection.

[0029] Specifically, the top of the connecting plate 4 and the bottom of the measuring body 3 are also connected with an extension rod 8. The extension rod 8 can increase the distance between the measuring body 3 and the connecting plate 4, and through the extension of the extension rod 8 during use, the measuring body 3 can extend to the external wider measuring area, which is convenient for subsequent accurate measurement.
