Description

Technical Field

[0001] This utility model relates to the field of industrial aluminum profile technology, and in particular to spliced ​​modular heat-resistant industrial aluminum profiles. Background Technology

[0002] The current improvement in the range of new energy vehicles and the popularization of fast charging technology have further increased the instantaneous temperature of battery packs. Industrial automation equipment is developing towards higher precision and higher load, and the continuous operation time is extended. In both scenarios, the demand for aluminum profiles to resist deformation in high-temperature environments (40-100℃) has increased significantly. For example, the long-term working temperature of battery packs reaches 60-80℃, which requires aluminum profiles to provide stable support and deformation that does not affect the assembly of components.

[0003] Traditional industrial aluminum profiles have significant drawbacks: First, the high coefficient of thermal expansion of 6061 aluminum alloy (approximately 23×10^-6 / ℃) and thermal deformation exceeding 0.5mm / m at 100℃ can easily lead to misalignment in equipment assembly. Second, the fixed structural design cannot adapt to different equipment specifications, requiring a complete replacement when needed, increasing costs by more than 30%. Third, long-term use at high temperatures can easily lead to fatigue cracking, resulting in a service life of only 2-3 years, which is insufficient to meet the long-term operating requirements of equipment.

[0004] To address this, a modular, heat-resistant industrial aluminum profile with splicing design is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular, heat-resistant, deformation-resistant industrial aluminum profile, comprising three aluminum profile bodies arranged in a three-dimensional layout and a splicing connection structure, wherein the splicing connection structure is located at the connection point of the three aluminum profile bodies, and the surface of the aluminum profile body is provided with a composite protective coating structure.

[0007] The splicing connection structure includes a connecting seat, which is located at the connection point of three aluminum profile bodies and is bolted to the bottom aluminum profile body.

Two positioning posts integral with the elastic sheets are fixedly connected to the inner wall of the elastic sheets. A positioning block is engaged on the opposite side of the two positioning posts, and a connecting block is fixedly connected to the side of the positioning block near the aluminum profile body. The other side of the connecting block is fixedly connected to the aluminum profile body.

The bottom of the middle locking bolt extends into the interior of the bottom aluminum profile body and is threaded to it. The bottom of the right and rear locking bolts extends into the interior of the positioning block and is threaded to it.

[0009] Preferably, countersunk holes are provided in the middle, right and rear sides of the connector, and the locking bolt is located inside the countersunk holes.

[0010] Preferably, the countersunk hole is filled with a removable sealing post, and the bottom of the sealing post is in contact with the locking bolt.

[0011] Preferably, the end of the positioning block away from the connecting block is provided with a curved protrusion, and the connection between the curved protrusion and the positioning block is provided with an arc transition portion, and the surface of the positioning post is in contact with the arc transition portion.

[0012] Preferably, both sides of the connecting block are provided with integrated guide blocks, and an anti-misalignment protrusion is provided on the outer side of one guide block, and both the guide block and the anti-misalignment protrusion are slidably disposed inside the connecting seat.

[0013] Preferably, the connecting seat has guide grooves on both the right and rear sides, and the guide block and the anti-misalignment protrusion are located inside the guide grooves.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application enables modular splicing and assembly between aluminum profile bodies by setting up a splicing connection structure, thereby adapting to equipment frames of different specifications, reducing customized production cycles, and lowering equipment maintenance and replacement costs. Furthermore, by setting up high and low temperature resistant elastic sealing gaskets at the splicing points of the aluminum profile bodies, it can offset slight thermal deformation under high temperatures, ensuring the sealing of the splicing gaps and improving positioning accuracy, thus meeting the stringent requirements of high-temperature industrial scenarios.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] The modular heat-resistant and deformation-resistant industrial aluminum profile consists of three aluminum profile bodies 1 arranged in a three-dimensional layout and a splicing connection structure 2. The splicing connection structure 2 is located at the connection of the three aluminum profile bodies 1, and the surface of the aluminum profile body 1 is provided with a composite protective coating structure 3.

[0030] The splicing connection structure 2 includes a connecting seat 21, which is located at the connection of three aluminum profile bodies 1 and is bolted to the bottom aluminum profile body 1. The right and front sides of the inside of the connecting seat 21 are provided with elastic pieces 22. The inner wall of the elastic piece 22 is fixedly connected to two positioning posts 23 integral with it. The opposite side of the two positioning posts 23 is engaged with a positioning block 24, and the side of the positioning block 24 close to the aluminum profile body 1 is fixedly connected to a connecting block 25. The other side of the connecting block 25 is fixedly connected to the aluminum profile body 1.

[0031] In this embodiment: By using the splicing connection structure 2, during splicing, the connecting seat 21 is initially positioned with the bottom aluminum profile body 1. Through the cooperation of the elastic sheet 22, positioning post 23, positioning block 24 and connecting block 25 inside the connecting seat 21, the aluminum profile body 1 on the right and front sides is connected to the connecting seat 21. The connecting block 25 drives the positioning block 24 to be inserted between the two positioning posts 23. The positioning post 23 clamps the positioning block 24 under the elastic action of the elastic sheet 22, realizing the three-dimensional connection of the three aluminum profile bodies 1, thereby adapting to equipment frames of different specifications, reducing the customized production cycle, and reducing equipment maintenance and replacement costs.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, locking bolts 4 penetrate the middle, right and rear sides of the connector 21. The bottom of the middle locking bolt 4 extends into the interior of the bottom aluminum profile body 1 and is threaded to it. The bottom of the right and rear locking bolts 4 extends into the interior of the positioning block 24 and is threaded to it.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, countersunk holes 5 are provided in the middle, right and rear sides of the connector 21, and the locking bolt 4 is located inside the countersunk holes 5.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, the countersunk hole 5 is filled with a removable sealing post 6, and the bottom of the sealing post 6 is in contact with the locking bolt 4.

[0035] In this embodiment: by installing locking bolts 4 through the middle, right, and rear sides of the connecting seat 21 and using countersunk hole 5 design, a reliable final locking in stages and functions is achieved. The middle bolts rigidly anchor the main body of the connecting seat 21 to the bottom aluminum profile body 1, establishing a stable foundation, while the bolts on the right and rear sides pass through the connecting seat 21 and are finally connected to the threads inside the positioning block 24. By tightening these locking bolts 4, the tension of the bolts firmly pulls the positioning block 24 toward the main body of the connecting seat 21, thereby tightly binding the aluminum profile body 1 to the connecting seat 21 through the connecting block 25, eliminating all assembly gaps and ensuring the connection strength at the connection point; the countersunk hole 5 is filled by the sealing post 6 to prevent dust, moisture and other impurities from entering the hole, avoid rusting and corrosion of the locking bolts 4, and ensure the flexibility of bolt disassembly and service life.

[0036] Specifically, such as Figure 3 As shown, the end of the positioning block 24 away from the connecting block 25 is provided with a curved protrusion, and the connection between the curved protrusion and the positioning block 24 is provided with an arc transition part, and the surface of the positioning post 23 is in contact with the arc transition part.

[0037] In this embodiment, the design of the curved protrusion and the arc transition reduces the difficulty of docking the positioning block 24 and the positioning post 23, enabling fast and accurate splicing and improving assembly efficiency. At the same time, the uniform contact area ensures that the clamping force is evenly distributed, ensuring that the positioning block 24 is firmly fixed and avoiding misalignment caused by uneven force under high temperature, thus improving splicing accuracy.

[0038] Specifically, such as Figure 5 As shown, guide blocks 7 are provided on both sides of the connecting block 25. An anti-misalignment protrusion is provided on the outer side of one guide block 7. Both the guide block 7 and the anti-misalignment protrusion are slidably disposed inside the connecting seat 21.

[0039] Specifically, such as Figure 5 As shown, guide grooves 8 are provided on the right and rear sides of the connecting seat 21, and guide blocks 7 and anti-misalignment protrusions are located inside the guide grooves 8.

[0040] In this embodiment: by setting guide blocks 7 and anti-misalignment protrusions on both sides of the connecting block 25, during the assembly process, the assembler only needs to align the connecting block 25 with the guide groove 8. The design of the anti-misalignment protrusions ensures that the connecting block 25 cannot be inserted in the wrong direction or position, so that the guide block 7 slides smoothly along the guide groove 8, bringing the positioning block 24 into the correct connection position with the positioning post 23. This not only facilitates the connection between the positioning post 23 and the positioning block 24, but also facilitates the subsequent connection between the locking bolt 4 and the positioning block 24.

[0041] Specifically, such as Figure 2 , Figure 3As shown, the connection between the connecting seat 21 and the aluminum profile body 1 is provided with a high and low temperature resistant elastic sealing gasket 9. The four corners of the connecting seat 21 near the aluminum profile body 1 are fixedly connected with guide posts 10, and the other end of the guide post 10 passes through the high and low temperature resistant elastic sealing gasket 9 and extends into the interior of the aluminum profile body 1.

[0042] In this embodiment, a high- and low-temperature resistant elastic sealing gasket 9 is provided between the contact surfaces of the connecting seat 21 and the aluminum profile body 1, and is positioned by a guide post 10. This achieves the triple functions of interface sealing, stress buffering, and precise alignment. During assembly, the guide post 10 is first inserted into the corresponding hole of the aluminum profile to complete the precise pre-positioning of the connecting seat 21 and the profile. The high- and low-temperature resistant elastic sealing gasket 9 is compressed between the two. The sealing gasket can maintain good elasticity at both high and low temperatures. It can seal the interface to prevent foreign objects from entering, and also act as a soft buffer layer to absorb and compensate for microscopic mismatches and displacements caused by manufacturing tolerances, installation stress, and temperature changes, thereby improving the long-term stability of the connection.

[0043] Specifically, such as Figure 6 As shown, the composite protective coating structure 3 includes a high-temperature resistant layer 31, which is uniformly coated on the outer surface of the aluminum profile body 1, and an anti-corrosion coating 32 is provided on the outer surface of the high-temperature resistant layer 31.

[0044] Specifically, such as Figure 6 As shown, the aluminum profile body 1 adopts an aluminum-aluminum nitride composite substrate, the high-temperature resistant layer 31 is a high-temperature resistant ceramic coating, and the anti-corrosion coating 32 is composed of polyurethane anti-corrosion varnish.

[0045] In this embodiment, the selection of the aluminum-aluminum nitride composite substrate of the aluminum profile body 1 reduces the coefficient of thermal expansion of the aluminum profile from the source, suppresses thermal deformation, and solves the core pain point of severe thermal deformation of traditional aluminum alloys. The high-temperature resistant ceramic coating has excellent high-temperature resistance and works synergistically with the composite substrate to further enhance the anti-thermal deformation effect. In addition, the anti-corrosion coating 32 composed of polyurethane anti-corrosion varnish has reliable anti-corrosion performance, is suitable for industrial environments, and extends the service life of the aluminum profile.

[0046] Working principle: During the assembly of the aluminum profile body 1, the connecting seat 21 is first connected to the bottom aluminum profile body 1. The middle bolts rigidly anchor the main body of the connecting seat 21 to the bottom aluminum profile body 1. Then, the middle sealing post 6 is filled into the middle countersunk hole 5. Then, the guide post 10 passes through the high and low temperature resistant elastic sealing gasket 9 and is inserted into the corresponding hole of the corresponding aluminum profile body 1 to achieve precise pre-positioning. Subsequently, the connecting blocks 25 of the right and front aluminum profile bodies 1 are aligned with the guide groove 8 of the connecting seat 21. The anti-misinstallation protrusion ensures the correct installation direction. The guide block 7 slides along the guide groove 8, driving the positioning block 24 to be inserted between the two positioning posts 23 of the elastic sheet 22. The starting part and the arc transition part are guided and connected. The positioning post 23 clamps the positioning block 24 under the action of the elastic plate 22 to complete the pre-fixation. Then, the locking bolts 4 on the right side and the rear side are tightened. The bolts on the right side and the rear side pass through the countersunk hole 5 and are screwed into the positioning block 24 to tighten the aluminum profile body 1 to eliminate the assembly gap. Finally, the sealing post 6 is filled into the countersunk hole 5 to achieve sealing protection. During the use of the aluminum profile body 1, the aluminum-aluminum nitride composite matrix of the aluminum profile body 1 and the high temperature resistant layer 31 work together to suppress thermal deformation, the anti-corrosion coating 32 resists corrosion, and the high and low temperature resistant elastic sealing gasket 9 buffers the stress caused by temperature changes. The elastic plate 22 and the positioning component offset slight thermal expansion and contraction to ensure the stability of the splicing structure.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
