[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1-5 A rotor dynamic balancing test bench includes a casing 1, a conveyor belt 2 and a motor to be tested 3. The conveyor belt 2 is located at the input end of the casing 1. A fixing seat 4 matching the motor to be tested 3 is provided on the surface of the conveyor belt 2. A sleeve 5 is provided on the top of the casing 1. A loading and unloading assembly is provided at the output end of the casing 1 corresponding to the conveyor belt 2. A testing assembly is provided at the output end of the loading and unloading assembly. A driving assembly is provided on the top of the testing assembly.

[0025] It should be noted that the conveyor belt 2 is of prior art and is driven by an intermittent motor.

[0026] Furthermore, a recovery slope 6 is fixedly connected to the output end of the corresponding conveyor belt 2 between the casings 1, and a unloading slope 7 is fixedly connected to the output end of the casing 1. When the fixed seat 4 leaves the output end of the conveyor belt 2, it falls into the unloading slope 7 under the action of gravity and slides out along the unloading slope 7.

[0027] Furthermore, the loading and unloading assembly includes a loading chute 8 and a unloading plate 9, a connecting frame 10 is fixedly connected between the loading chute 8, a fixed plate 11 is hinged at the output end of the loading chute 8, the bottom of the fixed plate 11 is fixedly connected to the casing 1, the unloading plate 9 is located at the bottom of the connecting frame 10, the bottom of the center of the unloading plate 9 passes through the surface of the casing 1 and is fixedly connected to the unloading push cylinder 12, and a limiting inclined surface 13 is provided on one side of the unloading plate 9.

[0028] A further advantage of adopting the above method is that the unloading plate 9 is pushed up by the unloading push cylinder 12, and the motor to be tested 3 is pushed out of the mounting seat 14 through the limiting inclined surface 13, thereby realizing the unloading function. The unloading push cylinder 12 continues to push the unloading plate 9 to rise, pushing the loading slide 8 to rotate along the fixed plate 11, and one end of the loading slide 8 contacts the two ends of the motor to be tested 3 and lifts it, so that the motor to be tested 3 slowly rolls into the mounting seat 14 along the loading slide 8. When the unloading push cylinder 12 is reset, the motor to be tested 3 enters between the positioning wheels 15 under the action of gravity, thereby realizing the loading function.

[0029] Furthermore, the test assembly includes multiple mounting seats 14, one side of the mounting seat 14 is rotatably connected to multiple positioning wheels 15, and the other side of the mounting seat 14 is fixedly installed with a vibration sensor 16, which collects dynamic balancing data of the rotor of the motor 3 to be tested.

[0030] Furthermore, the driving assembly includes a driving bow 17, and a plurality of driven wheels 18 are provided on one side of the driving bow 17 corresponding to the motor 3 to be tested, and a driving belt 19 is provided between the driven wheels 18. One side of the driving bow 17 is connected to a driving wheel 20 for rotation away from the motor, and one side of the driving wheel 20 passes through the driving bow 17 and is rotationally connected to the driving motor 21. A transmission belt 22 is provided between the driving wheel 20 and the driven wheel 18. An arc groove 23 is provided at the bottom of the driving bow 17 corresponding to the motor 3 to be tested, which is used to avoid the motor 3 to be tested. The top of one end of the driving bow 17 passes through the top of the shell and is fixedly connected to an adjusting push cylinder 24, and the top of the other end of the driving bow 17 is fixedly connected to a limiting rod 25, and the limiting rod 25 is slidably connected to the sleeve 5.

[0031] A further advantage of adopting the above method is that when the test is completed, the push cylinder 24 is adjusted to drive the drive bow 17 to reset, reserving space for the motor 3 to be tested to roll down. After the loading is completed, the push cylinder 24 is adjusted to drive the drive bow 17 to descend, and the drive motor 21 and the transmission belt 22 drive the driven wheel 18 to rotate, and the driven wheel 18 drives the drive belt 19 to run, and the drive belt 19 drives the motor 3 to be tested to rotate.

[0032] When the present invention is in use, the motor to be tested 3 placed in the fixed seat 4 is conveyed to the working area by the conveyor belt. At this time, the unloading pushing cylinder 12 continues to push the unloading plate 9 to rise, so that the middle section of the unloading plate 9 contacts and pushes the connecting frame 10, and the loading slide 8 is driven by the connecting frame 10 to rotate along the fixed plate 11. One end of the loading slide 8 contacts the two ends of the motor to be tested 3 and lifts it. After being lifted, the motor to be tested 3 slowly rolls into the mounting seat 14 along the loading slide 8 and is blocked by the right-angled part of the limiting inclined surface 13. When the unloading pushing cylinder 12 is reset, the motor to be tested 3 enters between the positioning wheels 15 under the action of gravity, and the loading is completed.

[0033] After the loading is completed, the push cylinder 24 is adjusted to drive the driving bow 17 to descend, and the driving motor 21 and the transmission belt 22 drive the driven wheel 18 to rotate, and the driven wheel 18 drives the driving belt 19 to run, and the driving belt 19 drives the motor 3 to rotate to realize the driving function, and the dynamic balance data of the rotor of the motor 3 to be tested is collected through the vibration sensor 16;

[0034] After the test is completed, the push cylinder 24 is adjusted to drive the driving bow 17 to reset, reserving space for the motor 3 to be tested to roll down. At the same time, the conveyor belt transports the next motor 3 to be tested to the input end of the loading and unloading assembly. At this time, after the fixed seat 4 retained in the previous process leaves the output end of the conveyor belt 2, it falls into the unloading slope 7 under the action of gravity and slides out along the unloading slope 7. Finally, the unloading push cylinder 12 pushes the unloading plate 9 to rise, and pushes the motor 3 to be tested out of the mounting seat 14 through the limiting slope 13. The pushed out motor 3 to be tested rolls out of the unloading slope 7 to realize the unloading effect. The unloading push cylinder 12 rises again to load again, so that the dynamic balancing test can be carried out continuously, thereby improving work efficiency.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
