Description

Technical Field

[0001] This utility model relates to the field of foam interlayer compaction technology, and in particular to a compaction device for bonding foam interlayers. Background Technology

[0002] Foam-skin interlayer bonding is a technique that connects the skin and foam core material with adhesive to form a sandwich structure with specific properties. Aluminum alloys and composite materials are commonly used for the skin, and foams such as PVC and polyurethane are used for the core material. The process involves surface treatment, adhesive coating, bonding assembly, and curing. It is widely used in aviation, shipbuilding and other fields.

[0003] After bonding the foam interlayer, it is usually necessary to use the hydraulic rod on the compaction device to compact the foam interlayer. The above and existing technologies have the following defects: Since the position of the hydraulic rod is fixed, the hydraulic rod can only compact a certain position of the foam interlayer, resulting in uneven force on the foam interlayer at different distances from the hydraulic rod. This reduces the quality of the compaction of the bonded interlayer and causes the product to be unqualified.

[0004] Therefore, a compaction device for bonding foam interlayer skin is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when using a hydraulic rod on a compaction device to compact the foam interlayer, the fixed position of the hydraulic rod results in uneven stress on the foam interlayer at different distances from the hydraulic rod, which reduces the quality of the compaction of the bonded interlayer and causes the product to be unqualified. Therefore, a compaction device for bonding foam interlayer is proposed.

Springs are fitted on the surfaces of the lifting frames.

[0011] The two ends of the spring are fixedly connected to the connecting plate and the mounting plate respectively, and the two lifting frames are fixedly inserted with locking rods.

[0012] The effect achieved by the above components is as follows: by setting up a compaction structure, the position of the hydraulic rod can be adjusted to compact different positions of the foam interlayer, effectively avoiding bonding defects caused by excessive or insufficient local pressure, and effectively ensuring the quality and reliability of the bonding of the skin foam interlayer.

The surfaces of the stops are fixedly installed with two clamping plates. The internal threads of the clamping plates are connected to positioning rods, and the surfaces of the positioning rods abut against the base frame.

[0020] The effect achieved by the above components is as follows: by setting the auxiliary structure, foam interlayers of different sizes can be limited, thereby reducing the shaking and displacement of the foam interlayers during the compaction process, greatly facilitating the compaction operation for workers, and effectively improving work efficiency and bonding quality.

[0021] Preferably, two fixing plates are fixedly installed on the surface of the base frame, and guide plates are rotatably connected to the surface of the fixing plates, with the surface of the guide plates abutting against the base frame.

[0034] 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.

[0035] 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.

[0036] like Figure 1-5 As shown, this utility model provides a compaction device for bonding foam interlayer, including a base frame 1. The surface of the base frame 1 is provided with a compaction structure 2. By setting the compaction structure 2, the position of the hydraulic rod 209 can be adjusted to compact different positions of the foam interlayer, effectively avoiding bonding defects caused by excessive or insufficient local pressure, and effectively ensuring the quality and reliability of the bonding of the foam interlayer. The surface of the base frame 1 is provided with an auxiliary structure 3. By setting the auxiliary structure 3, foam interlayers of different sizes can be limited, reducing the shaking and displacement of the foam interlayer during the compaction process, greatly facilitating the compaction operation for workers, and effectively improving work efficiency and bonding quality.

[0037] The specific setup and function of its compaction structure 2 and auxiliary structure 3 will be discussed below.

[0038] like Figure 2 , Figure 4 and Figure 5As shown, the compaction structure 2 includes two limiting rods 201. The surfaces of both limiting rods 201 are fixedly connected to the base frame 1. The arc surfaces of the two limiting rods 201 are slidably fitted with mounting plates 203. Several locking holes 202 are evenly distributed on the surfaces of the two limiting rods 201. Hydraulic rods 209 are fixedly installed inside the mounting plate 203. Two lifting frames 204 are slidably connected inside the mounting plate 203. The dimensions of the lifting frames 204 are adapted to the dimensions of the locking holes 202. The cross-section of the lifting frames 204 is "U" shaped. Locking rods 205 are fixedly installed on the surfaces of the two lifting frames 204. A connecting plate 2 is fixedly fitted on the surface of the lifting frames 204. 06. A spring 207 is fitted on the surface of the lifting frame 204. The two ends of the spring 207 are fixedly connected to the connecting plate 206 and the mounting plate 203 respectively. A locking rod 205 is fixedly inserted inside the two lifting frames 204. A support plate 208 is fixedly installed on the surface of the mounting plate 203. The surface of the support plate 208 abuts against the locking rod 205. The support plate 208 can prevent the lifting frame 204 from sliding further down with the help of the locking rod 205. The output end of the hydraulic rod 209 is rotatably connected to the pressure frame 212. Four positioning grooves 213 are evenly opened on the surface of the pressure frame 212. A balance plate 210 is fixedly installed on the output end of the hydraulic rod 209. The balance plate 210 has a sliding connection with a pin 211. The size of the pin 211 is adapted to the size of the positioning groove 213. With the help of the pressure frame 212, the staff can press the foam interlayer. Magnets 214 are fixedly installed on the inner walls of the four positioning grooves 213. The four pins 211 are iron pins. The magnets 214 can help limit the pins 211 in the positioning grooves 213.

[0039] like Figure 3 As shown, the auxiliary structure 3 includes two balance frames 36, the surfaces of which are fixedly connected to the base frame 1. Two baffles 37 are slidably mounted on the surfaces of the two balance frames 36. Several guide wheels 33 are uniformly rotatably connected to the surfaces of the baffles 37. Two clamping plates 34 are fixedly installed on the surfaces of the baffles 37. Positioning rods 35 are threadedly connected to the inside of the clamping plates 34. The surfaces of the positioning rods 35 abut against the base frame 1. Two fixing plates 32 are fixedly installed on the surfaces of the base frame 1. Guide plates 31 are rotatably connected to the surfaces of the fixing plates 32. The surfaces of the guide plates 31 abut against the base frame 1. The foam interlayer can move along the guide plates 31 onto the base frame 1. The cross-section of the two baffles 37 is U-shaped. The baffles 37 are made of iron, which increases the strength of the baffles 37.

[0040] The overall working principle is as follows: When it is necessary to compress the foam interlayer, the hydraulic rod 209 is activated. The hydraulic rod 209 drives the pressing frame 212 to move downward. During the movement of the pressing frame 212, the surface of the pressing frame 212 squeezes the foam interlayer, thereby compacting the foam interlayer. When it is necessary to compress other parts of the foam interlayer, the locking rod 205 is slid upward. While the locking rod 205 is sliding, it drives the lifting frame 204 to slide. After the lifting frame 204 slides a certain distance, it slides out of the inner wall of the locking hole 202 on the limiting rod 201. At this time, the mounting plate 203 and the limiting rod 201 are no longer fixed. Then the mounting plate 203 is slid. While the mounting plate 203 is sliding, it drives the hydraulic rod 209 to slide. After the hydraulic rod 209 slides to the desired position, the sliding of the mounting plate 203 is stopped, and then the locking rod 209 is released. 05. At this time, the connecting plate 206 on the lifting frame 204 slides downward under the tension of the spring 207. While the lifting frame 204 slides, it also drives the locking rod 205 to slide. After the locking rod 205 slides a certain distance, the surface of the locking rod 205 abuts against the support plate 208, so that the locking rod 205 cannot slide. At this time, the lifting frame 204 also engages with the inner wall of the corresponding locking hole 202 on the limiting rod 201, so that the mounting plate 203 and the limiting rod 201 are fixed together, and the hydraulic rod 209 is also fixed. At this time, the hydraulic rod 209 can be activated to compact the foam interlayer. By setting the compaction structure 2, the position of the hydraulic rod 209 can be adjusted to compact different positions of the foam interlayer, effectively avoiding bonding defects caused by excessive or insufficient local pressure, and effectively ensuring the quality and reliability of the bonding of the skin foam interlayer.

[0041] When it is necessary to compact foam interlayers of different sizes, the foam interlayer is first slid along the guide plate 31 onto the base frame 1. Then, the guide plate 31 is rotated so that it does not obstruct the sliding of the baffle 37. The baffle 37 is then slid towards the foam interlayer. As the baffle 37 slides, it drives the guide wheel 33 to slide. After the guide wheel 33 has slid a certain distance, its surface contacts the foam interlayer. Then, the positioning rod 35 is rotated. The positioning rod 35 moves towards the base frame 1 via the thread. After the positioning rod 35 has moved a certain distance, its surface presses against the base frame 1. At this point, the base frame 1 and the baffle 37 are fixed together. When compacting the foam interlayer, the shaking and displacement of the foam interlayer are reduced due to the limiting effect of the baffle 37. By setting the auxiliary structure 3, foam interlayers of different sizes can be limited, reducing the shaking of the foam interlayer during compaction. This greatly facilitates the compaction operation for workers and effectively improves work efficiency and bonding quality.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
