Description

Technical Field

[0001] The present application relates to the technical field of nested cylinder adhesive curing, and in particular to a nested cylinder adhesive curing device. Background Art

[0002] A nested cylinder refers to a structure in which cylinders are combined together in a nested manner. This structure usually includes one or more internal cylinders (inner cylinders) and an external cylinder (outer cylinder). The inner cylinder and the outer cylinder are connected to form a whole through a specific connection method (such as floor slabs, connectors, etc.). The nested cylinder structure can form a compact and efficient spatial layout, which is particularly suitable for occasions that require a large space and high structural performance requirements, such as the core tube design of high-rise buildings. Through the nested design, the interaction between the cylinders can significantly improve the overall stiffness and stability of the structure and enhance the structure's ability to resist lateral forces. When subjected to horizontal loads, the nested cylinder structure can transfer force to the foundation like a cantilever beam, effectively reducing the lateral displacement and deformation of the structure. This structure is widely used in the industrial field.

[0003] As the instruction manual Figure 1 The figure shows a nested cylinder structure, which includes an outer cylinder, an intermediate cylinder, and an inner cylinder with a step-type sleeve within the intermediate cylinder. The outer cylinder is made of metal, providing good external strength, and the inner cylinder is formed by carbon fiber compression molding, which can achieve ablation resistance. The inner cylinder is made of graphite, which also has ablation resistance and is resistant to acid and alkali corrosion. However, compared with the metal outer cylinder, the carbon fiber intermediate cylinder and the graphite inner cylinder are not easy to machine. Therefore, the intermediate cylinder and inner cylinder cannot be threaded together and connected to the outer cylinder in a nested structure. Currently, an adhesive process is used to achieve the tightness of the three after nesting.

[0004] At present, the curing time of adhesive bonding is usually long, about more than ten hours, so the relative positioning of the three needs to be maintained for a long time during the curing process. Due to structural limitations, it is difficult to press the three cylinders for a long time. In addition, during the adhesive bonding curing process, the curing state of the adhesive along the circumference is different, which will also cause the radial relative offset of the three cylinders (the adhesive at the cured area will shrink and harden, while the adhesive at the uncured area will not shrink, and the curing force will drive the cylinder to shift). As a result, after the curing is completed, there is a position deviation between the three cylinders, which affects the quality of the assembled cylinders. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a nested cylinder adhesive curing device, which solves the physical burden of long-term curing of the cylinder and solves the coaxial deviation effect caused by the adhesive on the cylinder during the curing process.

[0006] To achieve the above object, the technical solution adopted by the present application is as follows: A nested cylinder adhesive curing device, wherein the nested cylinder includes an outer cylinder, an intermediate cylinder sleeved in sequence, and an inner cylinder step-sleeved in the intermediate cylinder. The intermediate cylinder and the inner cylinder have a through hole. It is characterized in that: the curing device includes an assembly member that drives and positions the intermediate cylinder and the inner cylinder from both ends of the outer cylinder, and a positioning structure for coaxially positioning the outer cylinder, the intermediate cylinder, and the inner cylinder is also provided in the assembly member.

[0007] Preferably, the assembly member includes a bottom cover sleeved at the bottom end of the outer cylinder. An assembly screw passing through the through holes of the intermediate cylinder and the inner cylinder is provided at the center of the bottom cover. A pressing plate and a fastening nut that are pressed against the top end faces of the outer cylinder, the intermediate cylinder, and the inner cylinder are sequentially sleeved on the top of the assembly screw.

[0008] Preferably, the positioning structure includes setting the inner side surface of the bottom cover as an inclined surface structure, setting the assembly screw as a tapered rod structure, and providing a tapered cylinder on the bottom surface of the pressing plate that is embedded in the gap between the inner cylinder and the assembly screw.

[0009] Preferably, removable anti-sticking layers are provided on the inner part of the bottom cover, the outer peripheral surface of the assembly screw, and the bottom surface of the pressing plate.

[0010] The beneficial effect of the present application is that: the curing device can synchronously press and statically cure the three cylinders through the assembly member, solving the physical burden of manual long-term pressing. And through this positioning mechanism, the relative positions of the three cylinders can be mechanically restricted, thereby overcoming the problem that the coaxial positioning between the cylinders is affected due to the inconsistent state of the adhesive during the curing process.

[0020] In order to enable ordinary technicians in the field to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the drawings and embodiments.

[0021] Referring to Figures 1-9 A nested cylinder body glue curing device shown in the figure, and as Figure 1 shown, the nested cylinder body includes an outer cylinder body 1, an intermediate cylinder body 2 sleeved in sequence, and an inner cylinder body 3 sleeved in a stepped manner in the intermediate cylinder body 2. The intermediate cylinder body 2 and the inner cylinder body 3 have a mutually penetrating middle hole. Before curing, glue is coated on the inner wall of the outer cylinder body 1, the inner and outer walls of the intermediate cylinder body 2, and the inner wall of the inner cylinder body 3, and then they are nested in sequence as Figure 2 shown, and after nesting, they are left to stand for curing.

[0022] In order to solve the problem of realizing the relative positioning of the three cylinder bodies during the long-term curing process, and to solve the problem that the coaxial accuracy of the three cylinder bodies is affected by the inconsistent curing state of the glue during curing, this application is provided with a curing device, as Figure 4 shown, which includes an assembly member that drives and positions the intermediate cylinder body 2 and the inner cylinder body 3 from both ends of the outer cylinder body 1. After the three cylinder bodies are nested with each other, the three cylinder bodies can be synchronously pressed and left to stand for curing through this assembly member from both ends of the outer cylinder body 1, solving the physical burden of manual long-term pressing.

[0023] And in order to solve the problem of coaxial deviation and the increase of coaxial deviation between the three cylinder bodies caused by the inconsistent curing state of the glue during the curing process, as Figure 6 shown, a positioning structure for coaxial positioning of the outer cylinder body 1, the intermediate cylinder body 2, and the inner cylinder body 3 is also provided in this assembly member. Through this positioning mechanism, the relative positions of the three cylinder bodies can be mechanically restricted, thereby overcoming the problem that the coaxial positioning between the cylinder bodies is affected by the inconsistent state of the glue during the curing process.

[0024] Specifically, as Figure 4As shown, the assembly member includes a bottom cover 4 sleeved at the bottom end of the outer cylinder 1, and the bottom of the outer cylinder 1 can be fitted and embedded into the bottom cover 4. An assembly screw 5 is provided at the center of the bottom cover 4 and passes through the middle holes of the middle cylinder 2 and the inner cylinder 3. At the top of the assembly screw 5, a pressing plate 6 and a fastening nut 7 are sequentially sleeved, which are pressed against the top end faces of the outer cylinder 1, the middle cylinder 2, and the inner cylinder 3. As Figure 4 shown, after gluing and nesting the three cylinders, the assembly screw 5 is passed through the middle holes of the middle sleeve 2 and the inner sleeve 3, and the bottom of the outer cylinder 1 is embedded into the bottom cover 4. Then, the pressing plate 6 is sleeved on the top of the assembly screw 5 and abuts against the top faces of the three sleeves. Subsequently, the fastening nut is tightened to press the pressing plate 6 against the top faces of the three sleeves. Then, it can be left standing for the curing operation. After curing and forming, the assembly member can be disassembled to complete the curing operation of a single nested cylinder.

[0025] To achieve the coaxial positioning of the three cylinders during the curing process, as Figures 6-8 shown, the positioning structure includes setting the inner side surface of the bottom cover 4 as an inclined surface structure, which makes the inner wall surface of the bottom cover 4 form a circumferential inverted conical surface structure. After the outer cylinder 1 is embedded, it is in circumferential contact with the inverted conical surface, which can eliminate the embedding gap between the outer cylinder 1 and the bottom cover 4, thereby resisting the acting force during the curing of the adhesive.

[0026] As Figures 8-9 shown, the assembly screw 5 is set as a conical rod structure, which is the same as the inverted conical surface structure on the inner side of the bottom cover 4. During the process of sleeving the middle cylinder 2, the inner wall surface of the middle cylinder 2 gradually comes into circumferential contact with the outer wall surface of the assembly screw 5, which can also eliminate the passing gap between the two and resist the acting force during the curing of the adhesive.

[0027] As Figure 9 shown, a conical cylinder 61 is provided on the bottom surface of the pressing plate 6 and is embedded into the gap between the inner cylinder 3 and the assembly screw 5. The outer wall surface of the conical cylinder 61 is set as a conical surface structure. During the process of pressing and fastening by the fastening nut, the conical cylinder 61 is embedded into the gap between the inner cylinder 3 and the assembly screw 5, and the outer wall surface of the conical cylinder 61 gradually comes into circumferential contact with the top port of the inner cylinder 3, thereby eliminating the passing gap between the inner cylinder 3 and the assembly screw 5 and also being able to resist the acting force during the curing of the adhesive. Through this positioning structure, the axial positioning and fastening of the three cylinders are realized, overcoming the influence of the acting force during the curing (solidification) of the adhesive and improving the forming accuracy of the nested cylinder after curing.

[0028] Since the above three cylinders are all formed by adhesive curing connection, there is glue overflow during the embedding process and the subsequent curing process. The glue overflow will adhere to the assembly components, making it inconvenient to disassemble the assembly components after curing. Therefore, to solve this problem, preferably, a removable anti-sticking layer is provided on the inner surface of the bottom cover 4, the outer peripheral surface of the assembly screw 5, and the bottom surface of the pressing plate 6 (including the outer wall surface of the conical cylinder 61). The anti-sticking layer can preferably be a plastic film. After curing and forming, the plastic film can be torn off from the assembly components, facilitating the disassembly operation of the assembly components and the formed cylinder.

[0029] The principle of this application is as follows: When curing and forming the outer cylinder 1, the middle cylinder 2, and the inner cylinder 3, the three cylinders are coated with glue and nested. Then, the assembly screw 5 is passed through the middle holes of the middle sleeve 2 and the inner sleeve 3. The bottom of the outer cylinder 1 is embedded in the bottom cover 4 and is in circumferential (coaxial) contact with the inner wall of its inverted cone structure. At the same time, the middle cylinder 2 is coaxially connected to the assembly screw 5. Then, the pressing plate 6 is sleeved on the top of the assembly screw 5 and is attached to the top surfaces of the three sleeves. The outer wall surface of the conical cylinder 61 gradually makes circumferential contact with the top end opening of the inner cylinder 3, eliminating the through-gap between the inner cylinder 3 and the assembly screw 5. Then, by tightening the fastening nut, the pressing plate 6 is pressed tightly on the top surfaces of the three sleeves. Subsequently, the curing operation can be carried out by standing still. After curing and forming, the assembly components can be disassembled to complete the curing operation of a single nested cylinder.

[0030] The above shows and describes the basic principle, main features, and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
