Description

Technical Field

[0001] This utility model belongs to the field of generator rotor processing technology, and specifically relates to a generator rotor processing and flipping device. Background Technology

[0002] A generator rotor consists of a rotor core (or magnetic poles, yoke), windings, retaining rings, a center ring, slip rings, a fan, and a shaft. The rotor is the key component in a generator responsible for converting mechanical energy into electrical energy. It generates voltage and current by rotating and cutting magnetic lines of force, driving the output of electrical energy. During the machining of the generator rotor, periodic rotation is necessary to aid in maintenance, repair, and upkeep, ensuring its performance, balance, and reliability. This extends the rotor's lifespan and improves the generator's efficiency and reliability.

[0003] The existing patent, CN215452730U, entitled "A Tilting Device for Generator Rotor Processing," includes a base and an adjustment assembly. The base has bottom plates on both sides of its top, with the bottom of each plate connected to the top of a connecting block. The bottom of the connecting block penetrates the base and extends into the base to connect with the movable adjustment assembly. The adjustment assembly includes a dual-axis motor mounted at the center of the bottom of the inner wall of the base via a fixing plate. The output ends of the dual-axis motor are connected to one end of a threaded rod, and the end of the threaded rod away from the dual-axis motor is rotatably connected to both sides of the inner wall of the base.

[0004] Although the limiting plate of the above-mentioned flipping device can effectively fix the generator rotor, making it convenient for workers to adjust the flipping device according to different specifications of generator rotors, reducing the labor intensity of workers, improving the working efficiency of the flipping device, and effectively meeting the needs of workers, the limiting plate used in the clamping mechanism of the above-mentioned flipping device cannot be applied to the processing of rotors with different shapes and specifications, which has certain limitations.

[0028] The flipping mechanism 2 includes two first guide rails 201 mounted on the surface of the processing table 1 and extending longitudinally. A first guide block 202 is slidably connected to the surface of the first guide rail 201. A first movable seat 203 is fixed to the surface of the first guide block 202. Two transversely extending second guide rails 204 are fixed to the surface of the first movable seat 203. Two movable plates 205 are slidably connected to the surface of the second guide rails 204. A flipping shaft 206 is rotatably connected to the inner surfaces of the two movable plates 205. A connecting shaft 211 is rotatably connected to the surface of the two movable plates 205. One connecting shaft 211 is slidably connected to the inner wall of the other connecting shaft 211. A slot 213 is opened on the surface of one connecting shaft 211. A locking block 214 that matches the slot 213 is provided on the surface of the other connecting shaft 211. A first cylinder 210 is mounted on the inner surfaces of the two movable plates 205. A pulley 208 is fixedly connected to the surface of the flipping shaft 206 and the surface of the connecting shaft 211. The two pulleys 208 are rotatably connected through a transmission belt 209.

[0029] The lifting mechanism 3 includes two third guide rails 301 mounted on the surface of the processing table 1 and extending longitudinally. A second guide block 302 is slidably connected to the surface of the third guide rail 301. A second movable seat 303 is fixed to the surface of the second guide block 302. A lifting platform 304 is mounted on the upper surface of the second movable seat 303. The generator rotor can be placed and raised by the lifting mechanism 3. Then, rotors of different sizes can be clamped by the flipping mechanism 2. This reduces the labor intensity of the workers, improves the working efficiency of the flipping device, and enhances the practicality of the device.

[0030] Specifically, a servo motor 207 is mounted on the surface of one side of the movable plate 205, and the output shaft of the servo motor 207 is fixedly connected to one end of the flip shaft 206.

[0031] In a specific embodiment of this utility model, the servo motor 207 is started, and the output shaft of the servo motor 207 drives the one-sided flipping shaft 206 to rotate, thereby driving the generator rotor to flip.

[0032] Specifically, a second cylinder 212 is mounted on the back of the first movable seat 203, and the base of the second cylinder 212 is mounted on the surface of the processing table 1.

[0033] In a specific embodiment of this utility model, the piston rod of the second cylinder 212 is activated to drive the first movable seat 203 to move, thereby facilitating the movement of the generator rotor.

[0034] Specifically, a connecting seat 306 is installed on the inner side of the second movable seat 303, and a third cylinder 305 is rotatably connected to the surface of the connecting seat 306, and the base of the third cylinder 305 is rotatably connected to the surface of the processing table 1.

[0035] In a specific embodiment of this utility model, the piston rod of the third cylinder 305 is activated to drive the connecting seat 306 and the second moving seat 303 to move, thereby driving the generator rotor to move.

[0036] Specifically, rollers 307 are rotatably connected to both sides of the connecting seat 306, and the bottom height of the rollers 307 is less than the bottom height of the second movable seat 303.

[0037] In a specific embodiment of this utility model, the roller 307 prevents the second movable seat 303 from contacting the processing table 1, thereby increasing the service life of the second movable seat 303.

[0038] Specifically, the bottom of the processing table 1 is equipped with multiple support bases 4, and one side of each support base 4 is equipped with a corresponding reinforcing pad 5.

[0039] In a specific embodiment of this utility model, the combined use of the support base 4 and the reinforcing pad 5 increases the friction when the device contacts the ground, thereby increasing the stability of the device during use.

[0040] Working principle: First, the generator rotor is placed on the surface of the lifting platform 304. Then, the third cylinder 305 is activated. The piston rod of the third cylinder 305 drives the connecting seat 306 and the second moving seat 303 to move. At the same time, the second moving seat 303 drives the second guide block 302 to move on the surface of the third guide rail 301. At this time, the first cylinder 210 is activated, causing it to drive the two moving plates 205 to move on the surface of the second guide rail 204. At this time, the generator rotor is clamped by the flipping shaft 206. Then, the piston rod of the second cylinder 212 is activated, driving the first moving seat... 203 and the first guide block 202 move on the surface of the first guide rail 201, and then the servo motor 207 is started. The output shaft of the servo motor 207 drives a flip shaft 206 to rotate. At this time, under the action of the pulley 208 and the transmission belt 209 on one side, a connecting shaft 211 is driven to rotate. At this time, under the action of the slot 213 and the block 214, another connecting shaft 211 is driven to rotate. At the same time, under the action of the pulley 208 and the transmission belt 209 on the other side, another flip shaft 206 is driven to rotate, thereby realizing the flipping of the generator rotor.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
