However, traditional positioning toolings for drilling holes in special-shaped joints have problems such as inaccurate positioning, low production efficiency, and difficult tooling adjustment, especially for parts with complex shapes.

[0003] Such as Figure 3 the special-shaped joint shown, its structure is relatively special. When drilling and positioning are required for it, there is no specific tooling for positioning it. Usually, multiple clamps are needed to clamp and fix it. On the one hand, it is more difficult to adjust the clamps and the positioning is not accurate enough. On the other hand, the clamps are likely to damage the special-shaped joint during the clamping process. Summary of the Invention

[0004] This application aims to solve at least one of the above technical problems in the prior art to some extent. For this reason, an embodiment of this application provides a positioning tooling for drilling holes in special-shaped joints. Since the positioning groove is adapted to the shape of the special-shaped joint, it can more precisely clamp and position the special-shaped joint, and the clamping and positioning are more convenient.

[0005] A positioning tooling for drilling holes in special-shaped joints, used for clamping special-shaped joints, includes:

[0006] A base, on which a positioning groove is provided, and the positioning groove matches the shape of the special-shaped joint;

[0009] In an optional or preferred embodiment, one end of the positioning groove is provided with an outwardly expanding avoidance groove.

[0010] In an optional or preferred embodiment, the base is provided with a plurality of the positioning grooves, and the positioning grooves are arranged at intervals relative to each other, and the pressing plate can press on each of the special-shaped joints.

[0011] In an alternative or preferred embodiment, two of the positioning grooves are provided on the base, and the two positioning grooves are respectively located on both sides of the first threaded hole and are arranged opposite to each other.

[0012] Based on the above technical solution, the embodiments of the present application have at least the following beneficial effects: In the above technical solution, during use, the special-shaped joint is assembled into the positioning groove, and then the pressing plate is pressed on the special-shaped joint and the pressing plate is connected to the base, so that the pressing plate presses the special-shaped joint tightly on the base to achieve positioning of the special-shaped joint. Then, drilling can be performed on both ends of the special-shaped joint. This positioning tooling is specifically used to position the special-shaped joint. Since the positioning groove is adapted to the shape of the special-shaped joint, it can clamp and position the special-shaped joint more precisely, and the clamping and positioning are more convenient.

[0022] The complex shapes and precise requirements of aerospace industry parts make special-shaped joints a key part for connecting different components. The accurate positioning of these joints is crucial for ensuring the structural stability, performance safety, and long-term reliable operation of aircraft. However, traditional positioning fixtures for drilling special-shaped joints have problems such as inaccurate positioning, low production efficiency, and difficult fixture adjustment, especially for parts with complex shapes.

[0023] As Figure 3 shown in the special-shaped joint, its structure is relatively special. When it is necessary to perform drilling and positioning on it, there is no specific fixture for positioning it. Usually, multiple clamps are required to clamp and fix it. On the one hand, it is relatively difficult to adjust the clamps and the positioning is not accurate enough. On the other hand, the clamps are likely to damage the special-shaped joint during the clamping process.

[0024] Referring to Figure 1 、 Figure 2, this application provides a positioning tooling for punching an irregular joint, which is used to clamp the irregular joint 100 and includes a base 200 and a pressing plate 300.

[0025] The base 200 is provided with a positioning groove 210, the positioning groove 210 matches the outer shape of the irregular joint 100, the pressing plate 300 is used to press on the irregular joint 100, and the pressing plate 300 is detachably connected to the base 200.

[0026] During use, the irregular joint 100 is assembled into the positioning groove 210, then the pressing plate 300 is pressed on the irregular joint 100 and the pressing plate 300 is connected to the base 200, so that the pressing plate 300 presses the irregular joint 100 on the base 200 to achieve the positioning of the irregular joint 100, and then the two ends of the irregular joint 100 are punched. This kind of positioning tooling is specifically used to position the irregular joint 100, which can clamp and position the irregular joint 100 more accurately. Since the positioning groove 210 matches the outer shape of the irregular joint 100, it effectively prevents the irregular joint 100 from being clamped and damaged.

[0027] The first end 110 of the irregular joint 100 is used to horizontally process a through hole, and the second end 120 is used to vertically process a through hole.

[0028] In some embodiments, the base 200 is provided with a first threaded hole 310, the pressing plate 300 is provided with a second threaded hole 220, and the first threaded hole 310 is aligned with the second threaded hole 220 and can be connected by a fastener.

[0029] After the irregular joint 100 is assembled into the positioning groove 210, the pressing plate 300 is pressed on the irregular joint 100 to align the second threaded hole 220 with the first threaded hole 310, and then a fastener is screwed into the first threaded hole 310 and the second threaded hole 220 to make the pressing plate 300 press the irregular joint 100.

[0030] In some embodiments, the base 200 is provided with a plurality of positioning grooves 210, and the positioning grooves 210 are arranged at intervals relative to each other. The pressing plate 300 can press on each irregular joint 100. In this way, multiple irregular joints 100 can be positioned at one time, improving the punching efficiency of the irregular joint 100.

[0031] In some embodiments, the base 200 is provided with two positioning grooves 210, and the two positioning grooves 210 are respectively located on both sides of the first threaded hole 310 and are arranged opposite to each other.

[0032] As Figure 2 shown in the embodiment, the two positioning grooves 210 are arranged opposite to each other on the base 200 and are located on both sides of the first threaded hole 310. In this way, the pressure of the pressing plate 300 on the two irregular joints 100 is more uniform.

[0033] In this application, the pressing plate 300 is in a plate-like structure, and the second threaded holes 220 thereon are directly opened in the middle of the pressing plate 300.

[0034] In order to facilitate the removal of the special-shaped tooling from the positioning groove 210, in some embodiments, one end of the positioning groove 210 is provided with an outwardly expanding avoidance groove 230.

[0035] As Figure 1 shown, two outwardly expanding semi-circular avoidance grooves 230 are provided at the position of the positioning groove 210 corresponding to the first end 110 of the special-shaped joint 100. The avoidance grooves 230 facilitate the staff to insert their fingers to pick up the special-shaped joint 100.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0037] The above has described the embodiments of the present application in detail with reference to the drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
