Description

Technical Field

[0001] This utility model relates to the field of aviation sealant application technology, specifically to an automatic shaping and filling nozzle. Background Technology

[0002] In the field of aircraft manufacturing and maintenance, sealant application is a key step in ensuring the sealing performance of aircraft structures, and the filler process plays an important role in the sealing effect and structural integrity.

[0003] Currently, when applying sealant to corners in aviation applications, operators must first precisely apply masking tape around the area to be filled, then use a regular nozzle to extrude the adhesive line, followed by shaping the adhesive line with a scraper to meet requirements, and finally removing the masking tape to complete the application. This process is cumbersome and complex, not only consuming a lot of time but also resulting in low application efficiency. At the same time, the manual operation makes it difficult to ensure consistency and accuracy in each corner filling, leading to difficulties in forming the sealant and problems such as uneven adhesive line thickness and irregular shape, which affect the sealing quality and the appearance of the aircraft. Utility Model Content

[0004] This invention provides an automatic shaping filler nozzle to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic shaping and filling nozzle includes a connecting post and a shaping head. One end of the connecting post is provided with a glue gun connection part for detachable connection with an external glue gun. The surface of the shaping head is provided with a flat plane, and the flat plane of the shaping head is provided with a glue storage cavity. The glue storage cavity communicates with a through cavity inside the connecting post. A shaping port is opened on one side of the shaping head, which communicates with the glue storage cavity and is used for extruding and shaping the sealant.

[0007] Preferably, one end of the connecting column is connected to a universal rotating connecting part, the connecting column is rotatably connected to the shaping head through the universal rotating connecting part, and the universal rotating connecting part is used to adjust the shaping head to any angle and lock it.

[0008] Preferably, the universal rotating connector is provided with a through-hole, and the connecting column communicates with the glue storage cavity through the through-hole on the universal rotating connector.

[0009] Preferably, the shaping head has a positioning block on its plane, and the positioning block is located at the end of the glue storage cavity away from the shaping port.

[0010] Preferably, the shaping head has an L-shaped side plate on its flat surface, one end of which is connected to the surface of the positioning block, and the other end of which is located at the shaping opening.

[0011] Preferably, the top surface of the L-shaped side plate and the top surface of the positioning block are on the same plane, and the shaping head is integrally formed with the positioning block and the L-shaped side plate.

[0012] Preferably, the outer diameter of the glue gun connector is smaller than the outer diameter of the connecting post, and the glue gun connector and the connecting post are integrally formed.

[0013] Preferably, the glue gun connection includes a threaded section and a feed port, and the connecting post is threadedly connected to an external glue gun through the threaded section.

[0015] Preferably, the outer wall of the connecting column is connected with a plurality of anti-slip strips, and the plurality of anti-slip strips are equidistantly arranged along the circumferential direction of the connecting column.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-3 As shown, this utility model provides an automatic shaping and filling nozzle, including a connecting post 1 and a shaping head 2. One end of the connecting post 1 is provided with a glue gun connecting part 3 for detachable connection with an external glue gun. The surface of the shaping head 2 is provided with a flat surface, and the flat surface of the shaping head 2 is provided with a glue storage cavity 4. The glue storage cavity 4 communicates with the cavity inside the connecting post 1, and a shaping port 5 is opened on one side of the shaping head 2. The shaping port 5 communicates with the glue storage cavity 4 and is used for extruding and shaping the sealant.

[0026] Combination Figure 2 As shown, as a further step, one end of the connecting column 1 is connected to a universal rotating connecting part 6. The universal rotating connecting part 6 can be a universal adjustable ball joint, which is a technology that is well known and applied by those skilled in the art and will not be described in detail here. The connecting column 1 is rotatably connected to the shaping head 2 through the universal rotating connecting part 6, and the universal rotating connecting part 6 is used to adjust the shaping head 2 to any angle and lock it.

[0027] The universal rotating connector 6 allows for flexible adjustment of the shaping head 2 at any angle, and the adjusted angle can be firmly locked to ensure that the shaping head 2 can be stably maintained at the required angle during the corner filling process, meeting the construction needs under different working conditions.

[0028] As a further step, the universal rotating connector 6 is provided with a through-hole, and the connecting column 1 communicates with the glue storage cavity 4 through the through-hole on the universal rotating connector 6. The through-hole design ensures that the sealant injected through the connecting column 1 can flow into the glue storage cavity 4, which is beneficial for the corner filling construction of aviation sealant.

[0029] Combination Figure 1As shown, as a further step, the plane of the shaping head 2 is provided with a positioning block 7, and the positioning block 7 is located at the end of the glue storage cavity 4 away from the shaping port 5. The plane of the shaping head 2 is provided with an L-shaped side plate 8, one end of the L-shaped side plate 8 is connected to the surface of the positioning block 7, and the other end of the L-shaped side plate 8 is located at the shaping port 5.

[0030] Specifically, the positioning block 7 adopts a widened design. With its larger contact area and stable support structure, it can be accurately positioned when the construction and moving adhesive application work is carried out in this utility model, effectively preventing the deviation during the construction process, ensuring that the adhesive line is extruded evenly and smoothly, and effectively improving the quality and efficiency of corner filling construction.

[0031] As a further step, the top surface of the L-shaped side plate 8 and the top surface of the positioning block 7 are on the same plane. By making the top surface of the L-shaped side plate 8 perfectly flush with the top surface of the shaping head 2, they together form a continuous and flat operating plane, effectively avoiding the problem of sealant accumulation or poor flow caused by surface differences.

[0032] As a further step, the shaping head 2 is integrally formed with the positioning block 7 and the L-shaped side plate 8. This integral forming structure not only enhances the integrity and strength of the shaping head 2, but also avoids the problem of affecting the accuracy of the glue line due to the splicing of parts.

[0033] Furthermore, the outer diameter of the glue gun connecting part 3 is smaller than the outer diameter of the connecting post 1, and the glue gun connecting part 3 and the connecting post 1 are integrally formed. The integral forming of the connecting post 1 and the glue gun connecting part 3, as well as the integral forming of the shaping head 2, the positioning block 7, and the L-shaped side plate 8, are all made of plastic material, which can effectively reduce production costs. Moreover, the manufacturing process can adopt injection molding, which can reduce processing steps to a certain extent.

[0034] As a further step, the glue gun connection part 3 includes a threaded section 31 and a feed port 32, and the connecting post 1 is threadedly connected to the external glue gun through the threaded section 31.

[0035] The threaded interface design enables quick and secure installation of the nozzle with various compatible glue guns, ensuring stable delivery of sealant during transport and effectively preventing glue leakage.

[0036] Furthermore, the diameter of the connecting post 1 gradually decreases from the glue gun connecting part 3 towards the shaping head 2. The connecting post 1 adopts a gradient diameter design, with its diameter decreasing regularly from the glue gun connecting part 3 towards the shaping head 2. This design not only optimizes the flow path of the sealant and reduces flow resistance loss, but also ensures a better connection and fit with the shaping head 2. It also makes the connecting post 1 more ergonomic in terms of grip and operation, allowing construction personnel to operate it flexibly and accurately to complete corner filling operations under various complex working conditions.

[0037] As a further step, the outer wall of the connecting column 1 is connected with a plurality of anti-slip strips 9, which are equidistantly arranged along the circumference of the connecting column 1.

[0038] Specifically, the design of the anti-slip strip 9 effectively increases the friction when holding the nozzle, preventing slippage and loss of hand during operation, thus improving the construction experience and work accuracy.

[0039] The working principle and usage process of this utility model are as follows: In use, the connecting post 1 is connected to the glue gun through the threaded section 31 of the glue gun connecting part 3. Then, the glue gun push rod is pushed to move the sealant. During this process, the user adjusts the shaping head 2 to a suitable angle so that the positioning block 7 is attached to the surface of the area to be filled, and the glue storage cavity 4 corresponds to the area to be filled. As the sealant continues to move, it can be injected into the glue storage cavity 4 from inside the connecting post 1. Then, the connecting post 1 drives the shaping head 2 to move, so that the sealant accumulated in the glue storage cavity 4 can be squeezed out through the shaping port 5, achieving a shaping effect. Furthermore, when the shaping head 2 moves, the design of the positioning block 7 ensures accurate glue positioning and smooth movement without deviation, effectively guaranteeing the uniform and smooth extrusion of the glue line and improving the sealing quality.

[0040] Therefore, this utility model effectively simplifies the operation, saves time and effort, and ensures that the adhesive line is uniform and smooth, thereby improving the sealing quality and the appearance of the adhesive line.
