Description

Technical Field

[0001] This utility model relates to the technical field of rotor processing equipment, and in particular to a rotor sealing device. Background Technology

[0002] After the automotive generator rotor is assembled, it still needs to undergo dynamic balancing, rebalancing, and painting. To prevent iron filings and paint impurities from adhering to the magnets, a thin film or tape is usually applied to the circumference of the rotor to cover the magnets. The tape application is usually done manually, requiring workers to rotate the rotor while simultaneously winding the tape around its surface, which is very cumbersome and may even require two people to work together to ensure the smooth progress of the work. There is an urgent need for a simple rotor sealing device to improve work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a rotor sealing device to solve the problem of manual operation of rotor coating, which is time-consuming, labor-intensive, and has extremely low work efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rotor sealing device includes a base plate and a film coating mechanism, a rotating mechanism, and positioning columns disposed on the base plate. The tops of the two positioning columns are adapted to the two ends of the rotor. The rotating mechanism clamps the two end faces of the rotor and rotates the rotor. The film coating mechanism applies an adhesive film to the outer peripheral surface of the rotor.

[0005] A further technical solution is as follows: the coating mechanism includes a bracket, a cylinder, a U-shaped frame, hook plates, and a rotating shaft. The bracket is slidably mounted on the base plate and locked with bolts. The cylinder and the two hook plates are both mounted on the bracket. The U-shaped frame is mounted on the power output end of the cylinder. The two rotating shafts are rotatably mounted on the U-shaped frame and the hook plates, respectively. The film roll is set on the rotating shaft of the hook plate, and the soft roller is mounted on the rotating shaft of the U-shaped frame.

[0006] A further technical solution is that the soft roller is a rubber roller or a sponge roller.

[0007] A further technical solution is as follows: the rotating mechanism includes a motor, a main shaft, and a pin tailstock. The main shaft and the pin tailstock are disposed opposite to each other on the base plate. The working ends of the main shaft and the pin tailstock clamp the two end faces of the rotor. The power output end of the motor is connected to the power input end of the main shaft.

[0008] A further technical solution is: a limiting post is provided on the working end of the spindle, and the outer end of the limiting post is adapted to the fan of the rotor.

[0009] A further technical solution is: the positioning column includes an outer cylinder, an inner rod, and a locking screw. The outer cylinder is vertically mounted on the base plate, the inner rod is slidably mounted inside the outer cylinder, and the locking screw is threaded onto the outer cylinder and abuts against the inner rod.

[0010] A further technical solution is that a V-groove is provided at the top of the inner rod.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a rotor sealing device. The device uses a positioning pin to quickly position the rotor, then uses a rotating mechanism to clamp and rotate the rotor. Finally, the adhesive tape on the coating mechanism is pulled to the outer circumference of the rotor. The rotor rotates and pulls the adhesive tape, and the working end of the coating mechanism presses the adhesive tape tightly onto the rotor, ensuring that the adhesive tape can tightly cover the rotor's magnets and prevent the magnets from being affected by impurities. The device is easy and labor-saving to operate and greatly improves work efficiency. Attached Figure Description

[0022] This implementation example Figure 1 As shown, a rotor sealing device includes a base plate 1 and a film covering mechanism 2, a rotating mechanism 3, and positioning columns 4 disposed on the base plate 1. The tops of the two positioning columns 4 are adapted to the two ends of the rotor 5. The rotating mechanism 3 clamps the two ends of the rotor 5 and rotates the rotor 5. The film covering mechanism 2 covers the outer peripheral surface of the rotor 5 with adhesive film.

[0023] The two ends of the rotor 5 are respectively placed on the top of the two positioning posts 4. The film coating mechanism 2 is equipped with a rotatable roll of adhesive tape. The outer end of the adhesive tape is pulled to the outer periphery of the rotor 5. The rotating mechanism 3 rotates the rotor 5 and pulls the adhesive tape to rotate together, thus wrapping it around the rotor 5. When the rotor 5 rotates, the film coating mechanism 2 will also press the adhesive tape tightly onto the rotor 5, and finally complete the film coating work of the rotor.

[0024] Preferably, such as Figure 3 As shown, the laminating mechanism 2 includes a bracket 6, a cylinder 7, a U-shaped frame 8, a hook plate 9, and a rotating shaft 10. The bracket 6 is slidably mounted on the base plate 1 and locked by bolts. The cylinder 7 and the two hook plates 9 are both mounted on the bracket 6. The U-shaped frame 8 is mounted on the power output end of the cylinder 7. The two rotating shafts 10 are respectively rotatably mounted on the U-shaped frame 8 and the hook plate 9. The film roll 11 is fitted on the rotating shaft 10 of the hook plate 9, and the soft roller 12 is mounted on the rotating shaft 10 of the U-shaped frame 8.

[0025] The adhesive tape roll is mounted on the rotating shaft 10 and placed on the hook plate 9. The soft roller 12 is mounted on the rotating shaft 10 and placed on the U-shaped frame 8. During operation, the adhesive tape roll is pulled onto the rotor 5. The rotating mechanism 3 is started to rotate the rotor 5. During rotation, the adhesive tape is also pressed onto the rotor 5 by the soft roller 12, thus completing the coating process.

[0026] It is worth noting that the hook plate 9 facilitates the placement of the rotating shaft 10, thereby facilitating the replacement of the tape roll.

[0027] Preferably, the soft roller 12 is a rubber roller or a sponge roller.

[0028] Rubber rollers are harder and suitable for shallower magnets, resulting in tight compaction; sponge rollers are softer and suitable for deeper magnets, resulting in insufficient compaction.

[0029] Preferably, the rotating mechanism 3 includes a motor 13, a main shaft 14 and a pin tail seat 15. The main shaft 14 and the pin tail seat 15 are arranged opposite each other on the base plate 1. The working ends of the main shaft 14 and the pin tail seat 15 clamp the two end faces of the rotor 5. The power output end of the motor 13 is connected to the power input end of the main shaft 14.

[0030] Motor 13 drives main shaft 14 to rotate, which in turn rotates rotor 5. Ejector pin tailstock 15, in conjunction with main shaft 14, clamps both ends of rotor 5. Preferably, a limit post 16 is provided on the working end of the main shaft 14, and the outer end of the limit post 16 is adapted to the fan of the rotor 5.

[0031] The limit post 16 rotates with the working end of the spindle 14, and the limit post 16 rotates together with the fan.

[0032] Preferably, such as Figure 2As shown, the positioning post 4 includes an outer cylinder 17, an inner rod 18, and a locking screw 19. The outer cylinder 17 is vertically mounted on the base plate 1, the inner rod 18 is slidably mounted inside the outer cylinder 17, and the locking screw 19 is threaded onto the outer cylinder 17 and abuts against the inner rod 18.

[0033] The height of the inner rod 18 is adjustable and locked by the locking screw 19 to accommodate different diameters of the central shaft on the rotor 5.

[0034] Preferably, the top of the inner rod 18 is provided with a V-shaped groove.

[0035] The central shaft of rotor 5 is located on the V-groove, which serves as a temporary limit.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
