Description

Technical Field

[0001] This utility model relates to the field of motor rotor processing technology, specifically to a device for cleaning the surface of silicon steel sheets for motor rotors. Background Technology

[0002] The wound rotor is one of the main structural forms of induction motor rotors. Its core is usually made of laminated silicon steel sheets, with evenly distributed slots on the surface to accommodate the three-phase windings. The rotor windings are mostly connected in a star (Y) configuration, with each phase lead connected to slip rings on the shaft and then to an external circuit via brushes. This structure allows external resistors or control devices to be connected to the rotor circuit, thereby adjusting the motor characteristics and making it suitable for applications requiring high starting torque or speed regulation.

[0003] During the cutting and stamping processes, silicon steel sheets can accumulate stains on their surface. To avoid affecting their use, the surface of the hardware components needs to be cleaned. Simple rinsing with water or blowing with a fan is insufficient to remove stubborn stains such as residual cutting fluid and oil. Therefore, this paper provides a device for cleaning the surface of silicon steel sheets on motor rotors to solve the above problems. Utility Model Content

Two third support plates 11 are provided. A third servo motor 12 is fixedly installed on one side of the upper end of the third support plate 11. The third servo motor 12 is a forward and reverse reversible motor. A threaded rod 16 is connected to the output end of the third servo motor 12. A slide rod 13 is fixedly connected to the opposite side of the third support plate 11 and the third servo motor 12. The slide rod 13 facilitates the smooth movement of the movable block 14. The movable block 14 is slidably connected to the slide rod 13. An electric telescopic rod 15 is fixedly connected to one side of the top of the movable block 14. A pressure head 17 is fixedly connected to the output end of the electric telescopic rod 15 through the movable block 14. The threaded rod 16 is threaded inside the movable block 14. The pressure head 17 has a convex structure. Figure 6 As shown, the pressure head 17 has an internal shaft connected to a pressure roller 1701 at its bottom end. The pressure roller 1701 is directly opposite the cleaning belt 8. The pressure roller 1701 facilitates contact with the cleaning belt 8 and also facilitates the movement of the cleaning belt 8.

[0026] Combination Figure 3 and Figure 4As shown, a water pump 1801 is installed on the bottom side of the inside of the cleaning agent coating box 18. The output pipe of the water pump 1801 is connected to a nozzle 1802. The nozzle of the nozzle 1802 is directly facing the cleaning belt 8, so as to facilitate the spraying of cleaning agent on the bottom of the cleaning belt 8. The cleaning belt 8 runs through the upper interior of the cleaning agent coating box 18. A scraper 1901 is provided inside the upper interior of the impurity removal box 19. Several scrapers 1901 are provided. A drawer compartment 1902 is provided on the bottom side of the inside of the impurity removal box 19. The drawer compartment 1902 facilitates the cleaning of collected impurities. The cleaning belt 8 runs through the upper interior of the impurity removal box 19, and the scraper 1901 contacts the bottom side of the cleaning belt 8.

[0027] Combination Figure 2 As shown, the tensioning mechanism 9 includes a rocker arm 901, a limiting roller 902, a fixed rod 903, and a tension spring 904. Two tensioning mechanisms 9 are provided. The upper end of the rocker arm 901 is connected to the limiting roller 902 via a shaft. The fixed rod 903 is fixedly connected to the end of the rocker arm 901 away from the limiting roller 902. Tension springs 904 are connected to both sides of the middle of the fixed rod 903. The end of the rocker arm 901 away from the limiting roller 902 is hinged to the worktable 1. The end of the tension spring 904 away from the fixed rod 903 is connected to the worktable 1. The tension spring 904 can be used to... After the pressure head 17 rises, the dragging fixing rod 903 keeps the swing rod 901 vertical, which facilitates the bottom of the cleaning belt 8 to be tensioned upwards, and facilitates the placement and removal of silicon steel sheets. The limiting roller 902 rolls and connects the cleaning belt 8. A silicon steel sheet placement seat 10 is provided on the upper end of the worktable 1, located on one side of the pressure head 17.

At the same time, the third servo motor 12 drives the threaded rod 16 to rotate, and the threaded rod 16 drives the movable block 14 to reciprocate. When the cleaning belt 8 moves through the cleaning agent coating tank 18, the water pump 1801 draws the cleaning agent in the cleaning agent coating tank 18 to the spray nozzle 1802, and the cleaning agent is sprayed onto the cleaning belt 8 through the spray nozzle 1802. Then, when the cleaning belt 8 moves to the silicon steel sheet, the surface of the silicon steel sheet can be wiped and cleaned. After passing the silicon steel sheet, the cleaning belt 8 enters the impurity removal tank 19, and the impurities attached to the surface of the cleaning belt 8 can be scraped off by the scraper 1901, and the scraped impurities fall into the drawer compartment 1902.
