Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing and testing aircraft skins, and in particular relates to a sliding skin testing tool. Background Art

[0002] In the entire aircraft manufacturing process, the manufacturing cost of the skin accounts for a relatively large proportion of the total cost. The skin has many types, different shapes, complex surfaces and multiple curvatures. Inspection of the produced skin requires various special tools, which consumes a lot of manufacturing costs.

[0003] Traditional skin tooling is a special type, and one skin requires one set of tooling. There are many skins in an aircraft, and the cost of skin tooling is also increasing. Traditional tooling is in the form of internal surface inspection, and there is no more effective way to check whether the parts are qualified. This kind of traditional skin tooling has prominent problems:

[0004] 1. Traditional skin tooling is not universal, which increases the production cost of tooling;

[0005] 2. Traditional skin tooling cannot effectively test whether the aerodynamic shape of the parts is qualified;

[0006] 3. Traditional skinning tooling is relatively large and inconvenient to carry and operate.

[0007] The above problems not only bring troubles to the skin manufacturing, but also affect the delivery quality of the product. Therefore, it is necessary to design a new inspection tool to inspect the skin and save the skin manufacturing cost. Utility Model Content

[0008] In order to solve the above problems, the utility model proposes a sliding skin inspection tool for conveniently inspecting skins with different curvatures, which solves the problem that skins with different curvatures require different tooling for inspection, the inspection tooling is troublesome to replace, and the manufacturing cost is high.

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme, including a working platform, on which two slide rails are arranged in parallel, and on which several pairs of slide seats with corresponding positions are arranged, and a clamping plate seat is fixed by a pair of slide seats with corresponding positions, and the clamping plate seat and the slide seat are connected by two second angle seats and screws, and a mounting groove arranged in the vertical direction is provided on the clamping plate seat, and a replacement clamping plate is arranged in the mounting groove, and the shape of the upper end of the replacement clamping plate matches the skin to be inspected.

[0010] As a preferred solution of the utility model, a pressure plate for assisting in fixing the replacement card plate is also provided in the installation groove, a threaded hole communicating with the installation groove is provided on the side of the card plate seat close to the pressure plate, and a first bolt for tightening the replacement card plate is provided in the threaded hole.

[0011] As a second preferred solution of the utility model, a first angle seat is arranged on the side of the clamping plate seat, and a second bolt is arranged on the first angle seat.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model has good versatility. By replacing the card plate and the sliding design, it can inspect skins of different sizes, and both single and double curvature skins can be inspected;

[0014] 2. Replacing the pallet saves time and effort. At the same time, the sliding detection speeds up the acceptance time of the skin, reduces the rework rate of the skin, and improves the product quality of the skin. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation plan

[0019] The utility model adopts the following technical scheme, including a working platform 1, two slide rails 2 are arranged in parallel on the working platform 1, a plurality of pairs of corresponding slide seats 3 are arranged on the slide rails 2, scales are arranged on the slide rails 2, so as to accurately adjust the position of the slide seat 3, a card plate seat 4 is fixed by a pair of corresponding slide seats 3, the card plate seat 4 is connected to the slide seat 3 by two second angle seats 10 and screws, a mounting groove is arranged in the vertical direction on the card plate seat 4, a replacement card plate 5 is arranged in the mounting groove, the shape of the upper end of the replacement card plate 5 matches the skin 11 to be inspected, and skins of different shapes can be inspected by replacing different replacement card plates 5, the replacement card plate 5 is simple to replace, takes less time, and has high inspection efficiency.

[0020] As a preferred solution of the utility model, a pressure plate 6 for assisting in fixing the replacement card plate 5 is further provided in the installation groove, and a threaded hole communicating with the installation groove is provided on the side of the card plate seat 4 close to the pressure plate 6, and a first bolt 7 for tightening the replacement card plate 5 is provided in the threaded hole. By tightening the first bolt 7, the replacement card plate 5 is fixed and tightened by the pressure plate 6.

[0021] As a second preferred embodiment of the present invention, a first angle seat 9 is provided on the side of the clamping seat 4, and a second bolt 8 is provided on the first angle seat 9. By tightening the second bolt 8 downward, the second bolt 8 contacts the working platform 1 to lock the clamping seat 4.

[0022] The use of the utility model:

[0023] For a single-curvature skin 11, at least three replacement card plates 5 and their corresponding mounting devices are required; adjust the position of the slide seat 3 on the slide rail 2, and achieve precise adjustment through the scale on the slide rail 2. After reaching the target position, use the second bolt 8 to lock the card seat 4 on both sides to prevent errors in part manufacturing and inspection; use the pressure plate 6 and the first bolt 7 to install the replacement card plate 5 in the mounting groove on the card seat 4, and move the replacement card plate 5 in the middle position left and right to make the replacement card plate 5 move in a straight line along the slide rail 2 to verify whether the outer shape of the skin 11 is qualified. If the sliding is smooth, it proves that the shape and size of the skin 11 to be inspected meet the standards; it can effectively inspect arc parts and can comprehensively verify the entire outer shape arc surface of the parts.

[0024] For the skin 11 with double curvature, at least three replacement card plates 5 are required to support the skin 11, and the position of the slide seat 3 corresponding to the replacement card plate 5 on the slide rail 2 is adjusted, and the second bolt 8 is used to lock all the card plate seats 4 after reaching the target position. The pressure plate 6 and the first bolt 7 are used to cooperate to install the replacement card plate 5 corresponding to the shape of the skin 11 in the installation groove of the card plate seat 4; for the skin 11 with double curvature, the intermediate sliding inspection can no longer be used, but all the card plate seats 4 are locked, and the contact surface between the replacement card plate 5 and the skin 11 is checked to see whether the profile of the skin and the replacement card plate 5 fit. Whether the gap is uniform and whether the gap meets the tolerance requirements of the parts.
