Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stator production and processing equipment, specifically to a coating roller structure for a stator oil film coating device. Background Technology
[0002] During the stator oil film coating process, operators typically use hand-held oil-soaked felt or coating rollers to apply anti-rust oil to the inner and outer circumferential sidewalls of the stator. However, this method is not very effective. Because the stator core is made of stator laminations stamped from silicon steel coils, with a single layer thickness between 0.2mm and 0.25mm, the edges of keyways, small teeth, and other structures on the inner and outer circumferential sidewalls of the stator are quite sharp. Existing rollers typically use coating materials such as felt, which can be torn by the sharp edges of the stator's inner and outer walls during the coating process, resulting in foreign matter remaining on the inner and outer walls of the stator and affecting the production quality of the stator. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a coating roller structure for a stator oil film coating device, which can solve the problem of foreign matter residue on the stator surface caused by sharp edges such as keyways and small teeth on the stator surface scratching the coating material on the roller surface during the application of anti-rust oil.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0005] A coating roller structure for a stator oil film coating device includes a roller shaft, an oil storage box installed around the roller shaft, and the oil storage box being connected to an oil tank. Oil outlet holes are evenly opened on the outer wall of the oil storage box, and an external roller material is provided on the outer periphery of the oil storage box to absorb the rust-preventive oil flowing out of the oil outlet holes and apply it to the stator sidewall, while avoiding being scratched by the sharp structure of the stator surface.
[0006] The coating roller structure of the stator oil film coating device described above is made of polypropylene.
[0007] The above-mentioned stator oil film coating device has a coating roller structure in which the two ends of the roller oil storage box are respectively provided with inner grooves. A first deep groove ball bearing that is rotatably matched with the roller shaft is installed in the inner groove at the right end of the roller oil storage box, and a second deep groove ball bearing that is rotatably matched with the roller shaft is installed in the inner groove at the left end of the roller oil storage box.
[0008] The coating roller structure of the stator oil film coating device described above has a shoulder on the roller shaft located to the right of the first deep groove ball bearing to restrict the movement of the roller shaft.
[0009] In the above-mentioned stator oil film coating device, the coating roller structure is located on the left side of the first deep groove ball bearing, and the roller shaft is connected to the roller shaft fastener to prevent the roller shaft from moving to the right.
[0010] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.
[0011] This utility model provides a coating roller structure for a stator oil film coating device. By setting an external roller material made of polypropylene on the outer periphery of the roller oil storage box, the external roller material is prevented from being scratched by sharp edges such as keyways and small teeth on the stator surface during the oil film coating process. This solves the problem of foreign matter residue on the stator surface caused by sharp edges such as keyways and small teeth on the stator surface scratching the coating material on the roller surface during the application of anti-rust oil, thus improving the quality of stator oil film coating. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the specific structure of this utility model.
[0013] The components are: 1. Roller shaft, 2. Roller oil reservoir, 3. Roller external material, 4. First deep groove ball bearing, 5. Second deep groove ball bearing, 6. Roller shaft fastener, 7. Oil outlet. Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] A coating roller structure for a stator oil film coating device, such as Figure 1 As shown, it includes a roller shaft 1, a roller oil storage box 2 installed around the roller shaft 1, oil outlet holes 7 are evenly opened on the outer wall of the roller oil storage box 2, and roller external material 3 is provided on the outer periphery of the roller oil storage box 2, which can absorb the anti-rust oil flowing out from the oil outlet hole 7 and apply it to the stator side wall.
[0016] The outer coating material 3 of the roller is made of polypropylene to ensure that the outer coating material of the roller will not be snagged by the sharp structures on the inner and outer peripheral sidewalls of the stator during the coating process, so as not to cause part of the outer coating material of the roller to remain on the stator surface and affect the stator quality.
[0017] The roller oil storage box 2 has inner grooves at both ends. The first deep groove ball bearing 4, which is rotatably matched with the roller shaft 1, is installed in the inner groove at the right end of the roller oil storage box 2. A shoulder is provided on the roller shaft 1 located to the right of the first deep groove ball bearing 4 to restrict the movement of the roller shaft 1.
[0018] A second deep groove ball bearing 5 is installed in the inner groove at the left end of the roller oil storage box 2, which is rotatably matched with the roller shaft 1. The roller shaft 1 located to the left of the first deep groove ball bearing 5 is connected to the roller shaft fastener 6, thereby restricting the roller shaft 1 from moving to the right.
[0019] During use, the rust-preventive oil in the roller oil storage box 2 is discharged from the oil outlet 7 and absorbed by the roller external material 3 wrapped around the outside of the roller oil storage box 2. The roller external material 3 comes into contact with the stator surface, thereby applying the rust-preventive oil to the stator side wall. After the rust-preventive oil dries, an oil film is formed on the stator surface. In this process, because the roller external material is made of polypropylene, it is not easily scratched by the keyways, small teeth and other sharp edges on the stator surface, and no residual impurities are generated on the stator surface during the coating process, which improves the quality of the stator oil film coating.
[0020] This utility model provides a coating roller structure for a stator oil film coating device. By setting an external roller material made of polypropylene on the outer periphery of the roller oil storage box, the external roller material is prevented from being scratched by sharp edges such as keyways and small teeth on the stator surface during the oil film coating process. This solves the problem of foreign matter residue on the stator surface caused by sharp edges such as keyways and small teeth on the stator surface scratching the coating material on the roller surface during the application of anti-rust oil, thus improving the quality of stator oil film coating.
