Description

Technical Field

[0001] This utility model relates to the field of aviation equipment manufacturing, and in particular to a tool for detecting the height of pod rivets. Background Technology

[0002] During the installation of a certain type of aircraft pod shell, a large number of countersunk rivets and screws are required. The installation accuracy of these rivets and screws significantly affects the safety and reliability of the aircraft pod, and also impacts the subsequent painting quality. Therefore, after installation, the exposed height of the rivets and screws needs to be checked to determine if they meet the installation accuracy requirements. Currently, the commonly used inspection method relies primarily on manual visual inspection, judging whether the height meets the installation accuracy requirements based on human experience. However, the exposed height is typically only 0.1mm, which is impossible to detect using manual visual inspection alone. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a tool for detecting the height of pod rivets. This tool can be used to detect the exposed height of countersunk rivets and screws on the outer surface of aircraft pod shells. Moreover, it has high detection accuracy and can effectively replace the traditional manual visual inspection process, thereby improving detection efficiency and quality.

[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a tool for detecting the height of a pod rivet includes a tooling body, the tooling body adopts a rectangular block structure, a rectangular notch is machined on one side of the bottom of the rectangular block structure, a hand-held part is formed at the location of the rectangular notch, a detection block is provided on the opposite side of the hand-held part, and a detection height difference A is set between the detection bottom surface of the detection block and the contact bottom surface of the tooling body.

[0005] Preferably, the tooling body is made of stainless steel block.

[0006] Preferably, the detection block adopts a rectangular block structure.

[0007] Preferably, the detection block is located at the lower middle part of the front end face of the tooling body.

[0008] Preferably, the detection height difference A is 0.1 mm.

[0009] Preferably, the detection block and the tooling body adopt an integrated structure and are machined by milling.

[0010] The present invention has the following beneficial effects: 1. The tool of this utility model can be used to detect the exposed height of countersunk rivets and screws on the outer surface of aircraft pod shells. Moreover, it has high detection accuracy and can effectively replace the traditional manual visual inspection process, thereby improving detection efficiency and quality.

[0011] 2. By setting the detection height difference A, the maximum height difference between countersunk rivets and screws can be limited. When the height difference exceeds 0.1mm, it will not pass through, thus achieving the purpose of detecting the installation accuracy of countersunk rivets and screws.

[0012] 3. The above-mentioned detection block can be used to subsequently detect the height of countersunk rivets and screws.

[0013] 4. The 0.1mm mentioned above represents the maximum permissible height for countersunk rivets and screws. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] See Figure 1-4 A tool for detecting the height of pod rivets includes a fixture body 1, which has a rectangular block structure. A rectangular notch 3 is machined on one side of the bottom of the rectangular block structure, forming a handhold 6. A detection block 2 is provided on the opposite side of the handhold 6. A detection height difference A is set between the detection bottom surface 5 of the detection block 2 and the mating bottom surface 4 of the fixture body 1. This tool can be used to detect the exposed height of countersunk rivets and screws on the outer surface of aircraft pod shells, and it offers high detection accuracy. It can effectively replace the traditional manual visual inspection process, significantly improving detection efficiency and quality.

[0022] Furthermore, the tooling body 1 is made of stainless steel. The use of stainless steel ensures the structural strength and stability of the tooling body 1, effectively preventing deformation. It also provides excellent rust prevention.

[0023] Furthermore, the detection block 2 adopts a rectangular block structure. The detection block 2 described above can be used for subsequent detection of the height of countersunk rivets and screws.

[0024] Furthermore, the detection block 2 is positioned at the lower middle part of the front end face of the tooling body 1. This arrangement ensures that the detection block 2 can make full contact with the countersunk rivets and screws during the inspection process, thereby improving inspection efficiency.

[0025] Furthermore, the detection height difference A is set to 0.1 mm. This 0.1 mm represents the maximum permissible height for countersunk rivets and screws.

[0026] Furthermore, the detection block 2 and the tooling body 1 adopt an integrated structure and are machined by milling. The integrated structure simplifies its structure.

[0027] The working process and principle of this utility model: In the specific working process, through machining, the outer surface of the shell is used as the reference surface for bonding, and the maximum protrusion height allowed by the process is milled out. The tail of the detection tool is designed with a hand-held part 6 for easy hand holding. By sliding the bonding bottom end surface 4 on the shell surface, the detection block 2 is used to detect the height of rivets or screws. When the rivets or screws exceed the height allowed by the process, the detection block 2 cannot pass through. The maximum allowable height is 0.1mm. In this way, rivets and screws that do not meet the process requirements can be quickly detected.
