Description

Technical Field

[0001] This utility model relates to the field of heat insulation coating preparation technology, and specifically provides a roller coating preparation device for heat insulation coating of cylindrical parts. Background Technology

[0002] Cylindrical parts typically refer to parts with a cylindrical shape. They are widely used in various fields such as machinery manufacturing, aerospace, and automotive industries. The roller coating process for cylindrical parts is a technique used to coat the inner surface of the parts with paint, which has advantages such as high paint utilization and good coating thickness consistency.

[0003] In the production process of roller coating of cylindrical parts, the inconsistent adjustment of the distance between the two ends of the drive shaft and driven shaft of the roller coating machine makes it impossible to adjust the axis of the cylindrical shell to a horizontal state, which easily causes uneven coating thickness. In addition, due to the insufficient roundness of the parts during roller coating, irregular circles are formed during rolling, which will cause the cylindrical shell to jump during the roller brushing, thus affecting the leveling of the inner surface of the coating and ultimately resulting in poor uniformity of the prepared coating.

[0004] For the roll coating of thermal insulation coatings on cylindrical parts, the existing preparation method usually involves placing the cylindrical part directly on a roller and using limiting devices at both ends. During the roll coating process, the thermal insulation coating is first introduced into the inner cavity of the part, and then the part is rolled by the rotation of the roller, so that the coating is applied to the inner cavity of the part. After a long roll coating period, when the coating solvent evaporates, the coating adheres to the inner cavity of the part.

[0005] Existing preparation methods have the following drawbacks: 1. The structure of the roller coating device is unreasonable, which can easily cause parts to fall off the roller, posing a safety hazard; 2. The uniformity of the coating after roller coating is not high, which may lead to quality problems; 3. The roller coating time is long and the production efficiency is low. To avoid the above problems, it is necessary to design a roller coating preparation device for thermal insulation coatings on cylindrical parts. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-4 The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and do not constitute a limitation thereof.

[0026] A roller coating apparatus for preparing a heat-insulating coating on cylindrical parts, such as Figure 1 As shown, it includes a worktable 1, on which a heating assembly and a clamping assembly located to the side of the heating assembly are provided. Figure 1 On the left, the supporting component is located Figure 1 On the right side, the clamping assembly includes a chuck assembly for clamping the cylindrical part 5 and a drive motor 3 for driving the cylindrical part 5 to rotate. The heating assembly includes a carrier 6 slidably disposed on the worktable 1 and a heating plate assembly located on the carrier 6.

[0027] The number of chuck groups is two or more arranged sequentially from top to bottom. Each chuck group includes multiple multi-jaw chucks, and each multi-jaw chuck clamps a cylindrical part 5. The multi-jaw chucks in different chuck groups can clamp cylindrical parts 5 of different lengths. For example... Figure 1 , Figure 2 As shown, the multi-jaw chuck is a three-jaw chuck 2. The three-jaw chuck 2 includes three clamping jaws 8 evenly arranged in a 360° direction. The inner wall of the clamping jaws 8 is provided with at least three stepped clamping platforms 9. The clamping inner diameter of the clamping platforms 9 increases sequentially from bottom to top.

[0028] The number of chuck groups is three sets arranged from top to bottom. Each chuck group is driven by a drive motor 3. The three-jaw chuck 2 can hold cylindrical parts 5 with different outer diameters through the stepped clamping table 9, which has high versatility. At the same time, each set of three-jaw chucks 8 is driven by a different drive motor 3, which can further improve concentricity and ensure the uniformity of the heat insulation coating.

[0029] The three-jaw chuck 2 in the bottommost chuck group can clamp cylindrical parts 5 with a length greater than that clamped by the three-jaw chuck 2 in the uppermost chuck group. The heating plate 7 in the bottommost heating plate group has a length greater than that in the uppermost heating plate group. The chuck group in this application can clamp cylindrical parts 5 of different lengths at the same time, which further improves versatility. At the same time, the bottommost chuck group can clamp long cylindrical parts 5, which can process heat-insulating coatings on cylindrical parts 5 in various scenarios.

[0030] like Figure 1 , Figure 4 As shown, the workbench 1 is equipped with a support frame 10 for supporting the cylindrical part 5 in the lowest set of chucks. The support frame 10 includes a central receiving groove 11 and a second receiving groove 12 perpendicular to the receiving groove 11. The second receiving groove 12 is arranged parallel to the axis of the cylindrical part 5, and the axis of the cylindrical part 5 is as follows. Figure 4 As shown in the F direction, support wheels 13 are provided on both sides of the receiving groove 2 12. The support wheels 13 are housed in the receiving groove 1 11. The support wheels 13 and the support frame 10 can stably support the long cylindrical part 5.

[0031] The heating assembly includes a carrier 6 slidably mounted on the worktable 1 and a heating plate group located on the carrier 6. The heating plate group is matched and corresponding to the chuck group. Specifically, there are two or more heating plate groups arranged sequentially from top to bottom. In this embodiment, there are three heating plate groups matched and corresponding to the chuck group. Each heating plate group includes multiple heating plates 7. The heating plates 7 heat the cylindrical part 5 on the outside of the cylindrical part 5. Each heating plate 7 is used to heat one cylindrical part 5. The heating plates 7 in different heating plate groups can heat cylindrical parts 5 of different lengths respectively. In this embodiment, the heating plates 7 in the bottommost heating plate group have a larger length and width to match the heating requirements of the bottommost long cylindrical part 5.

[0032] A protective device 4 is provided at one end of the cylindrical part 5 near the heating assembly, and the protective device 4 prevents the paint inside the cylindrical part 5 from flowing out, such as... Figure 3As shown, the protective device 4 specifically includes a feed through hole 14, which is matched with the inner hole of the cylindrical part 5. The wall of the feed through hole 14 extends inward and is provided with an anti-overflow platform 15. The anti-overflow platform 15 is used to prevent the heat insulation coating inside the cylindrical part 5 from flowing out. Multiple mounting grooves 16 are evenly distributed on the anti-overflow platform 15. The mounting grooves 16 are fan-shaped groove structures. The mounting grooves 16 are used to prevent tooling from being used to install the protective device 4 onto the cylindrical part 5 more conveniently. The outer end face of the protective device 4 includes a straight section 17. Since the outer end face of the protective device 4 is a whole circle, it is easy to wear and inconvenient to stack and store. The straight section 17 makes the protective device 4 easier to place. At the same time, the outer end face of the protective device 4 is not easy to wear, which can improve the service life and quality of use.

[0033] like Figure 1 As shown, the workbench 1 is provided with a sliding rail 18 located below the heating plate 7. The lower end of the carrier 6 is provided with a slider that matches the sliding rail 18. The carrier 6 can drive the heating plate 7 to slide on the sliding rail 18 toward the cylindrical part 5. A driving member 19 is provided at the end of the carrier 6 away from the cylindrical part 5.

[0034] In this embodiment, each chuck group includes four three-jaw chucks 2, and each heating plate group includes four heating plates 7, totaling 12 three-jaw chucks 2 and 12 heating plates 7, which can simultaneously perform heat insulation coating roller coating operation on 12 cylindrical parts 5.

[0035] In use, first clean the cylindrical part 5 with compressed air. Scratches should be sanded with fine sandpaper and then cleaned again. Any small amounts of debris should be cleaned with a towel soaked in anhydrous ethanol. Install the protective gear 4 onto the cylindrical part 5. Then place the cylindrical part 5 onto the three-jaw chuck 2. The three-jaw chuck 2 clamps and centers the cylindrical part 5. After clamping the cylindrical part 5 onto the three-jaw chuck 2, the coaxiality between the cylindrical part 5 and the three-jaw chuck 2 should be ≤0.2mm. Next, prepare the heat-insulating coating according to the usage requirements. Introduce the required amount of heat-insulating coating into the inner cavity of the cylindrical part 5 through the feed port 14 of the protective gear 4. Then perform pre-coating by starting the drive motor 3 and rotating the cylindrical part 5 at a uniform speed to evenly coat the heat-insulating coating into the inner cavity of the cylindrical part 5. The uniform rotation time during pre-coating is 15-30 minutes. Then, heating is performed. The heating assembly is moved to the outside of the cylindrical part 5 on the sliding track 18 by the driving component 19. The heating power and the heating distance between the heating assembly and the outer surface of the cylindrical part 5 are controlled to control the surface temperature of the cylindrical part 5. Then, heating and roller coating are performed. The cylindrical part 5 is rotated at a uniform speed, and the heating plate 7 on the heating assembly continues to heat until the heat insulation coating stops flowing.

[0036] While the cylindrical part 5 is heated and cured, it is rolled. Centrifugal force can be used to completely and evenly cover the heat insulation coating on the cylindrical part 5, thus preparing a heat insulation coating with high uniformity. Heating can also accelerate the reaction speed of the coating, shorten the production cycle, and improve production efficiency.

[0037] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
