Technical Field
[0001] This utility model relates to the field of coating devices for uniformly applying composite materials to the outer wall of shafts, specifically a uniform coating device for polymer composite materials. Background Technology
[0002] Polymer composite materials have excellent wear resistance and impact resistance. When pits or dents appear on the surface of metal parts during use, a more economical and practical repair method is to apply polymer composite materials to the surface of the metal parts to cover the damaged areas. After the composite material has been thermo-cured, it can then be polished.
[0003] In the existing technology, during the process of applying composite polymer material to the surface of the shaft, it is not easy to smooth the bottom of the shaft, which will result in the composite polymer material at the bottom of the shaft being in a thicker state, increasing the workload of subsequent grinding.

[0018] 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.
[0019] Please see Figures 1-5In this embodiment of the present invention, a polymer composite material uniform coating device includes two semi-annular coupling clamps 1. The coupling ends of the two coupling clamps 1 are integrally formed with outwardly protruding coupling heads 2. The upper and lower coupling heads 2 are fixedly connected by bolts and nuts. When the coupling head 2 is in a tightened state, it drives the coupling clamp 1 to be clamped on the outer periphery of the shaft to be repaired. One side of the coupling clamp 1 is formed with an inwardly recessed first annular groove 3, and another side of the coupling clamp 1 is formed with an inwardly recessed second annular groove 4. The second annular groove 4 is located on the inner periphery of the first annular groove 3. The inner walls of the first annular groove 3 and the second annular groove 4 are connected by connecting mechanisms. One end of the connecting mechanism is fixedly installed with a scraper 5.
[0020] In this embodiment: when repairing the worn surface of a shaft with composite material coating, two mating clamps 1 are clamped onto the surface of the shaft and the mating joint 2 is fixed with bolts and nuts. At this time, the two mating clamps 1 are clamped to the outer wall of the shaft. Then, a scraper 5 of suitable length is selected and connected to the connecting mechanism. During the connection process, attention should be paid to the thickness between the bottom end of the scraper 5 and the shaft. This thickness should meet the preset thickness of the composite material coating. After the connection is completed, the scraper 5 can be rotated around the outer circumference of the shaft by rotating the scraper 5. During this process, the scraper 5 can evenly coat the composite coating on the outer circumference of the shaft to achieve a consistent coating thickness.
[0021] Please refer to this carefully. Figure 2 and Figure 3 The connecting mechanism includes a first sliding block 6 that is slidably connected to the inner wall of the first annular groove 3 and a second sliding block 7 that is slidably connected to the inner circumference of the second annular groove 4. The outer side of the first sliding block 6 is integrally formed with a first locking post 8 that extends to the outside of the docking hoop 1. The outer side of the second sliding block 7 is integrally formed with a second locking post 9 that extends to the outside of the docking hoop 1. One end of the first locking post 8 and the second locking post 9 is provided with an inwardly recessed docking groove. A scraper 5 is inserted into the inner wall of the docking groove.
[0022] In this embodiment: When installing the scraper 5, one end of the scraper 5 is engaged with the mating groove inside the first locking post 8 and the second locking post 9, and then installed. After installation, when the scraper 5 is pulled to rotate circumferentially, the scraper 5 drives the first sliding block 6 to rotate in the first annular groove 3 through the first locking post 8 and the second locking post 9, and drives the second sliding block 7 to move in the second annular groove 4, thereby achieving the purpose of circumferential rotation of the scraper 5.
[0023] Please refer to this carefully. Figure 4 and Figure 5 The first snap-fit post 8 has a through hole 10 longitudinally inside, and the scraper 5 has a groove 11 that is aligned with the through hole 10 inside. The groove 11 is vertically arranged, and the back end of the first snap-fit post 8 is shorter than the front end of the first snap-fit post 8.
[0024] In this embodiment: After one end of the scraper 5 is engaged with the mating groove, the distance between the scraper 5 and the outer periphery of the shaft is measured. If the distance is not up to standard, the height of the scraper 5 is adjusted by pulling it up and down until the bottom end of the scraper 5 and the outer periphery of the shaft meet the requirements. At this time, the bolt is passed through the through hole 10 and the groove 11, and the nut is used to tighten it until it is completely tightened, so that the scraper 5 can be fixed.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
