Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, and in particular to a glue scraping mechanism and sealing device. Background Technology

[0002] The most commonly used materials in aircraft parts manufacturing are carbon fiber and glass fiber. The matrix of these composite materials is mostly made of epoxy resin. Resin-based composite parts are easily affected by humid air. Moisture in humid air can easily penetrate into the interior of the parts and cause damage, and may even affect the mechanical properties. In order to prevent performance degradation and improve surface condition, and reduce adverse effects such as crack propagation and electrochemical corrosion, it is necessary to seal the cut edges of composite parts.

[0003] Currently, composite materials have diverse configurations. Sealing the edges of composite parts typically involves applying sealant. After application, some sealant needs to be scraped off to ensure consistent sealant thickness at different locations along the edge's extension direction (e.g., length or width). A consistent sealant thickness evenly distributes stress at the cut edge, inhibiting microcrack propagation. However, in existing technologies, after applying sealant, a layered progressive scraping method is commonly used to remove some of the sealant. This method involves using a specialized scraper (such as a carbide tip) to scrape off the sealant in multiple stages: the first layer removes approximately 90% of the sealant, followed by fine finishing to the target thickness. This method is inefficient and makes it difficult to control the sealant thickness at different locations along the edge of the composite part's extension direction.

[0004] Therefore, there is an urgent need for a glue scraping mechanism and sealing device to solve the above problems. Utility Model Content

[0006] The second objective of this invention is to provide a sealing device that improves the sealing effect on the edges of composite material parts.

[0007] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0012] Furthermore, the scraping mechanism also includes a fixing structure. The guide plate has mounting holes spaced apart from the V-groove, and the scraper has an elongated hole. The fixing structure can pass through and be fixed to the mounting holes and the elongated hole to fix the scraper to the guide plate.

[0013] Furthermore, the length direction of the elongated hole is parallel to the length direction of the scraper, and the scraper can move relative to the guide plate along the length direction of the elongated hole.

[0014] Furthermore, the scraping part is one end of the scraper in its length direction.

[0015] Furthermore, the guide plate is also provided with a guide groove, the mounting hole is located in the guide groove, part of the scraper is located in the guide groove, and the length direction of the elongated hole is parallel to the length direction of the guide groove.

[0016] Furthermore, the guide groove is a through groove, and the shape of the scraper matches the shape of the guide groove.

[0023] The beneficial effects of this utility model are:

[0024] This invention provides a sealant scraping mechanism, including a guide plate and a scraper. The guide plate has a V-groove that aligns with the workpiece to be processed. The bottom of the V-groove is spaced at a preset distance from the workpiece, and the guide plate can move along the edge of the workpiece. The scraper is adjustablely mounted on the guide plate and has a scraping portion. In the thickness direction of the guide plate, a portion of the scraping portion is projected into the V-groove. This scraping portion is used to scrape off a portion of the sealant at the edge of the workpiece. During use, the bottom of the V-groove is spaced at a preset distance from the workpiece. The scraper is adjustablely mounted on the guide plate to adjust the distance between the scraping portion and the edge of the workpiece, thus adjusting the target thickness.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This invention provides a sealant scraping mechanism that has high sealant scraping efficiency and accurate control of sealant thickness.

[0043] For example, such as Figures 1-6 As shown, the adhesive scraping mechanism includes a guide plate 1 and a scraper 2. The guide plate 1 has a V-groove 11, which can mate with the workpiece to be processed (not shown in the figure). The bottom of the V-groove 11 is spaced at a preset distance from the workpiece to be processed, and the guide plate 1 can move along the edge of the workpiece to be processed. The scraper 2 is adjustablely mounted on the guide plate 1 and has an adhesive scraping part 21. In the thickness direction of the guide plate 1, the projection of part of the adhesive scraping part 21 is located in the V-groove 11. The adhesive scraping part 21 is used to scrape off part of the sealant at the edge of the workpiece to be processed. During use, the bottom of the V-groove 11 is spaced at a preset distance from the workpiece to be processed. The scraper 2 is adjustablely mounted on the guide plate 1 to adjust the distance between the scraping part 21 and the edge of the workpiece to be processed, thereby adjusting the target thickness. As the guide plate 1 moves along the edge of the workpiece to be processed, the scraper 2 moves accordingly to scrape off the already applied sealant, making the sealant layer thickness consistent along the extension direction of the workpiece edge, i.e., at different positions in the direction of movement of the guide plate 1. The sealant scraping efficiency is high, the operation is simple, and the relative position of the scraper 2 and the guide plate 1 remains unchanged during the movement of the guide plate 1, so the sealant thickness control is more accurate.

[0044] Furthermore, since the scraper 2 is adjustablely mounted on the guide plate 1 to adjust the distance between the scraper part 21 and the edge of the workpiece to be processed, different target thicknesses can be determined according to actual usage requirements. In other words, different thicknesses of sealant to be retained can be determined according to actual usage requirements, which are suitable for different production needs.

[0045] It should be noted that, in this embodiment, the workpiece to be processed refers to the composite material part to which sealant is to be applied. The sealant is applied to the cut edge of the composite material part, referred to as the edge of the workpiece to be processed. The target thickness refers to the thickness of the sealant to be retained.

[0046] In this embodiment, as Figure 1 and Figure 5 As shown, the V-groove 11 is an inverted V-shape. The V-groove 11 is formed at one end of the guide plate 1. When the V-groove 11 is connected to the workpiece to be processed, part of the workpiece to be processed is located inside the V-groove 11 and abuts against the groove wall of the V-groove 11. The V-groove 11 can be made by forming an isosceles triangular block on one side of the guide plate 1.

[0047] Furthermore, such as Figures 1-3 As shown, the adhesive scraping mechanism also includes a fixing structure 3. The guide plate 1 has mounting holes 12 spaced apart from the V-groove 11, and the scraper 2 has an elongated hole 22. The fixing structure 3 can pass through and be fixed to the mounting holes 12 and the elongated hole 22 to fix the scraper 2 to the guide plate 1. It can be understood that by setting the fixing structure 3, mounting holes 12, and elongated holes 22, during installation, the scraper 2 can be fixed to the guide plate 1 directly by passing the fixing structure 3 through and fixing it to the mounting holes 12 and the elongated hole 22. This facilitates installation and enables a detachable connection between the guide plate 1 and the scraper 2. After the adhesive scraping mechanism completes the scraping process, the guide plate 1 and the scraper 2 can be thoroughly cleaned, improving the cleaning effect.

[0048] In this embodiment, as Figure 4 As shown, the length direction of the elongated hole 22 is parallel to the length direction of the scraper 2, allowing the scraper 2 to move relative to the guide plate 1 along the length direction of the elongated hole 22. Specifically, the depth direction of the V-groove 11 is parallel to the length direction of the scraper 2. When the scraper 2 moves relative to the guide plate 1 along the length direction of the elongated hole 22, the area of ​​the scraper 2 covering the V-groove 11 gradually increases or decreases. In other words, when the scraper 2 moves relative to the guide plate 1 along the length direction of the elongated hole 22, the distance between the scraper 2 and the workpiece gradually increases or decreases. That is, the position of the scraper 2 relative to the guide plate 1 is adjusted through the elongated hole 22 to meet actual usage requirements.

[0049] Furthermore, such as Figure 4 As shown, the scraping part 21 is one end of the scraper 2 along its length. It can be understood that by setting one end of the scraper 2 along its length as the scraping part 21, when the scraper 2 moves relative to the guide plate 1 along its length, the distance between the scraping part 21 and the edge of the workpiece to be processed gradually increases or decreases to determine the target thickness.

[0050] Furthermore, such as Figure 5 and Figure 6 As shown, the guide plate 1 is also provided with a guide groove 13, the mounting hole 12 is located in the guide groove 13, part of the scraper 2 is located in the guide groove 13, and the length direction of the elongated hole 22 is parallel to the length direction of the guide groove 13. It can be understood that by setting the guide groove 13, when the scraper 2 moves along the length direction of the guide groove 13, the guide groove 13 can guide the scraper 2, so that the scraper 2 moves smoothly.

[0051] In this embodiment, the guide groove 13 is formed on one side of the guide plate 1, and the V-shaped groove 11 is formed on the bottom wall of the guide groove 13 and located at one end of the guide plate 1, so that the scraper 2 moves relatively smoothly.

[0052] Furthermore, such as Figure 1 and Figure 6 As shown, the guide groove 13 is a through groove, and the shape of the scraper 2 matches the shape of the guide groove 13. It can be understood that the matching shape of the scraper 2 with the guide groove 13 facilitates the movement of the scraper 2 within the guide groove 13, improving the stability of the scraper 2's movement. Simultaneously, it guides the movement of the scraper 2, keeping its length parallel to the length of the guide groove 13, thereby ensuring that the scraping part 21 is perpendicular to the length of the guide groove 13, and preventing the sealant plane of the workpiece after scraping from tilting in the direction of the scraping mechanism's movement.

[0053] For example, the width of the scraper 2 is the same as the width of the guide groove 13. When the scraper 2 moves along the length direction of the guide groove 13, the two side walls of the guide groove 13 in its width direction can limit the scraper 2, so that the scraper 2 can continue to move relative to the guide groove 13 in its length direction. When adjusting the position of the scraper 2, it can prevent the scraper 2 from deviating or tilting.

[0054] As another example, the length of the scraper 2 is the same as the length of the guide groove 13. It can be understood that by setting the length of the scraper 2 to be the same as the length of the guide groove 13, the scraper 2 can be completely located within the guide groove 13, which reduces the space occupied by the scraping mechanism during transportation and facilitates transportation.

[0055] As another example, the thickness of the scraper 2 is the same as the depth of the guide groove 13. It can be understood that the scraper 2 does not protrude from the guide groove 13 along its length, resulting in a flatter overall appearance, reducing the space occupied by the scraping mechanism, and facilitating transportation.

[0056] In this embodiment, in addition to the scraping part 21, the edge of the scraper 2 can be chamfered to facilitate the installation of the scraper 2 into the guide groove 13.

[0057] To further improve the control accuracy of sealant thickness, in this embodiment, the sealant scraping mechanism also includes a feeler gauge (not shown in the figure). The feeler gauge can be positioned between the sealant scraping section 21 and the workpiece to be processed. Before applying the sealant, the feeler gauge is placed between the workpiece to be processed and the sealant scraping section 21 of the scraper 2 to ensure that the gap size is the same as the sealant thickness, thereby ensuring that the sealant thickness obtained after scraping is the target thickness. In this embodiment, the feeler gauge is a conventional feeler gauge, which is prior art and will not be described in detail here.

[0058] In this embodiment, the fixing structure 3 includes bolts and nuts. The bolts and nuts cooperate to fix the scraper 2. When it is necessary to fix the scraper 2, the bolts pass through the fixing hole and the elongated hole 22, and then cooperate with the nuts to fix the scraper 2.

[0059] Furthermore, the angle range of the V-groove 11 is 15°-45°, that is, the included angle between the two inclined groove walls of the V-groove 11 ranges from 15° to 45°. In this embodiment, the angle of the V-groove 11 can be 15°, 20°, 25°, 30°, 35°, 40°, and 45°, etc., and the specific angle can meet the actual usage requirements.

[0060] In this embodiment, the top corner (not shown in the figure) of the V-groove 11 is rounded, and the position where the V-groove 11 contacts the guide plate 1 can be rounded. The edges on the guide plate 1 are cut into arc surfaces, which makes it smoother to use and can avoid damaging the workpiece and affecting the surface quality of the workpiece when docking with it.

[0061] This embodiment also provides a sealing device, including the above-mentioned adhesive scraping mechanism, which improves the sealing effect on the edges of composite material parts.

[0062] In this embodiment, the above-mentioned scraping mechanism is used to scrape off the sealant after it has been applied. The sealant scraping efficiency is high, the sealant thickness is controlled more accurately, and the sealing effect on the edges of composite material parts is improved.

[0063] In this embodiment, the sealing process for the edge of the workpiece to be processed is as follows: First, the scraper 2 is installed on the guide plate 1, and the V-groove 11 is secured to both sides of the edge of the workpiece. Then, a feeler gauge is placed between the workpiece and the scraper 2 to ensure that the gap size is the same as the thickness of the sealant to be retained, and the guide plate 1 and the scraper 2 are fixed using the fixing structure 3. Next, sealant is applied, and excess sealant is evenly applied to the edge of the workpiece to be processed, ensuring that the amount of sealant per unit area is approximately the same. Then, keeping the guide plate 1 perpendicular to the surface to be sealed, the sealant is scraped along the edge of the workpiece.

[0064] Furthermore, after sealing the edge of the workpiece to be processed, the fixing structure 3 can be removed, the guide plate 1 and the scraper 2 can be disassembled, and the workpiece to be processed, the guide plate 1 and the scraper 2 can be cleaned.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
