[0002] In a motor, the rotor is the rotating part, which mainly consists of a rotating shaft, a rotor core and a rotor winding. Before the rotor is installed in the motor, dynamic balance detection is required. A rotor with good dynamic balance will not generate vibration and noise during rotation. After the rotor is produced and processed, balance detection needs to be carried out on the rotor.

[0003] According to the Chinese patent with the publication number: CN219935196U, a dynamic balance detection device for a motor rotor includes a base and support frames arranged on both sides of the base. Rotating support parts for supporting the rotation of the rotor are arranged on both support frames, and a synchronous transmission mechanism is arranged on the base; the synchronous transmission mechanism includes a mounting plate arranged on the base, a synchronous pulley set mounted on the mounting plate, and a synchronous belt body that cooperates with the synchronous pulley set. A driving motor for connecting with the synchronous pulley set to drive the synchronous belt body to transmit is arranged on the mounting plate, and the synchronous belt body is used to abut against the outer surface of the rotor.

[0004] In the above solution, the rotor is driven to rotate by the driven synchronous pulley and the synchronous belt body, and then detected by a photoelectric sensor, resulting in the following disadvantages: when using this detection device, for rotors produced in large quantities, each needs to be detected one by one, making the detection process time-consuming and extending the entire production cycle.

[0005] The purpose of the utility model is to provide a balancing mechanism for rotor detection to solve the problem that when using this detection device, for rotors produced in large quantities, each needs to be detected one by one, making the detection process time-consuming and extending the entire production cycle.

[0006] To achieve the above-mentioned utility model object, the present utility model adopts the following technical solutions: A balancing mechanism for rotor detection, including a base, on which a number of rotor bodies are placed. At the middle position of the top surface width of the base, a support plate is fixed. On the top surface of the base, two movable plates are movably arranged, and the two movable plates are respectively located on the front and rear sides of the support plate. On the top surfaces of the two movable plates, a number of U-shaped seats are respectively fixed. At the top end of the U-shaped seat, a rotating wheel is rotatably arranged. The end of the rotor body is placed between two adjacent rotating wheels. At the front side of the outer wall of the support plate, a synchronous belt body is rotatably arranged. The inner wall of the synchronous belt body is in contact with the outer walls of a number of rotor bodies. At the rear side of the outer wall of the support plate, a driving motor is fixed. At the left and right ends of the front wall of the support plate, two first synchronous belt wheels are respectively rotatably arranged. The two first synchronous belt wheels are respectively in transmission connection with the synchronous belt body. The right first synchronous belt wheel is fixed to the output shaft of the driving motor. At the front side of the outer wall of the support plate, two second synchronous belt wheels are rotatably arranged. The two second synchronous belt wheels are respectively in transmission connection with the synchronous belt body. At the rear end of the top surface of the base, a number of L-shaped frames are fixed. Inside the top surfaces of the number of L-shaped frames, photoelectric sensors are respectively detachably arranged.

[0007] Preferably, a baffle is fixed between two adjacent U-shaped seats, and a stop block is arranged inside the baffle.

[0008] Preferably, two installation grooves are formed on the top surface of the base corresponding to the movable plates. Inside the two installation grooves, first hydraulic push rods are respectively fixed.

[0013] 1. During use, several rotating wheels are beneficial for supporting multiple rotor bodies, and several photoelectric sensors are beneficial for simultaneously detecting the dynamic balance of multiple rotor bodies. Thus, it is not necessary to perform individual detections, which is conducive to improving the detection efficiency and shortening the production cycle.

[0014] 2. During use, the front end and the rear end of the rotor body are blocked by a baffle and a stopper, which is beneficial for preventing the rotor body from falling during detection, thereby improving the stability of the rotor body during detection. By starting the first hydraulic push rod, the moving plate can be adjusted up and down, which can drive the U-shaped seat and the rotating wheel to move up and down, thereby driving the rotor body to move up and down, realizing the tension adjustment of the synchronous belt body, and being beneficial for detecting rotor bodies of different sizes.

[0015] 3. During use, the moving plate is limited by a limiting hole and a limiting post, which is beneficial for preventing the moving plate from shifting, thereby improving the stability of the moving plate during lifting. The photoelectric sensor can be disassembled and assembled by the staff through a connecting plate and bolts, which is convenient for the staff to maintain or replace the photoelectric sensor. By starting the second hydraulic push rod, the stopper can be moved back and forth, so as to block rotor bodies of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS

Several U-shaped seats 5 are respectively fixed on the top surfaces of the two moving plates 4. A rotating wheel 6 is rotatably arranged at the top end of the U-shaped seat 5. The end of the rotor body 2 is placed between two adjacent rotating wheels 6. A synchronous belt body 7 is rotatably arranged on the front side of the outer wall of the support plate 3, and the inner wall of the synchronous belt body 7 is in contact with the outer walls of several rotor bodies 2. A driving motor 8 is fixed on the rear side of the outer wall of the support plate 3. Two first synchronous belt wheels 9 are respectively rotatably arranged at the left and right ends of the front wall of the support plate 3, and the two first synchronous belt wheels 9 are respectively in transmission connection with the synchronous belt body 7.

[0023] In use, the staff first place the rotor bodies 2 between the two front rotating wheels 6 and the two rear rotating wheels 6 respectively, so that several rotor bodies 2 are respectively within the synchronous belt body 7 and are supported by the rotating wheels 6. Then, the driving motor 8 is started to make the first synchronous belt wheel 9 rotate, and then the synchronous belt body 7 rotates, and at the same time the second synchronous belt wheel 10 rotates, so as to drive several rotor bodies 2 to rotate simultaneously. Then, several photoelectric sensors 12 are respectively used to detect the dynamic balance of several rotor bodies 2. The rotating wheels 6 are beneficial to supporting multiple rotor bodies 2, and the photoelectric sensors 12 are beneficial to simultaneously detecting the dynamic balance of multiple rotor bodies 2, so that it is not necessary to detect them one by one, which is beneficial to improving the detection efficiency and shortening the production cycle.

[0024] As Figures 1-3 shown, a baffle 13 is fixed between two adjacent U-shaped seats 5, and a stopper 14 is arranged on the inner side of the baffle 13.
