Description

Technical Field

[0001] The present application relates to the technical field of rotor dynamic balancing, and in particular to a correction device for rotor dynamic balancing. Background Art

[0002] Rotor dynamic balancing refers to the dynamic balancing of the rotor when it rotates at high speed, so that the rotor will not vibrate or resonate when it rotates at high speed, ensuring that the equipment runs smoothly, safely and reliably.

[0003] In order to measure and correct the dynamic balance of the rotor, a special correction device is generally used. The correction device usually needs to detect the rotor first, determine the imbalance of the rotor by rotating measurement, and determine the position and size of the imbalance point on the rotor based on the test results. Then, balancing mass can be added to the rotor by sticking balancing blocks on the rotor or drilling holes and adding lead blocks at specific locations. After adding the balancing mass, a balancing test is performed again to ensure that the vibration of the rotor is effectively controlled when it rotates at high speed.

[0004] However, conventional correction devices can only detect and correct rotors of a single size. Therefore, when faced with rotors of different sizes, it is necessary to prepare correction devices that are compatible with them. This results in poor flexibility of the correction device and reduces the working range of the correction device. Therefore, it is necessary to provide a rotor dynamic balancing correction device to solve the above problem.

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0040] like Figure 1-Figure 2 As shown, the present application provides a correction device for the dynamic balance of a rotor, including a fixed base 1, a fixed plate 11 is fixedly installed on the upper end of the fixed base 1, an arc groove is opened on the upper end of the fixed plate 11, so as to facilitate the placement of the rotor 5 to be corrected, and a driving mechanism 2 is installed on one side of the fixed plate 11, and the driving mechanism 2 is used to place and drive the rotor 5 to rotate, so as to facilitate the dynamic balance detection of the rotor 5.

[0041] In order to improve the rotation stability of the rotor 5, two groups of support plates 12 are fixedly installed on the upper end of the fixed seat 1, and the two groups of support plates 12 are arranged on both sides of the fixed plate 11, and two groups of rotating wheels 13 are rotatably connected to one end surface of the support plate 12 facing the fixed plate 11. The two groups of rotating wheels 13 are symmetrically arranged with respect to the central axis of the support plate 12, and the two groups of rotating wheels 13 protrude from the support plate 12. In the present application, the distance between the rotating wheels 13 is smaller than the diameter of the rotating shaft of the rotor 5, so as to facilitate the rotation of both sides of the rotor 5 for placement and transmission.

[0042] The driving mechanism 2 has a first pulley 21 and a second pulley 22 rotatably connected to one side of the fixed plate 11, and the first pulley 21 and the second pulley 22 are respectively located on both sides of the arc groove on the fixed plate 11, and a driving wheel 23 is rotatably connected to the fixed plate 11, and the driving wheel 23 is located below the second pulley 22, and a driving motor 26 is fixedly installed on the side of the fixed plate 11 away from the driving wheel 23, and the output shaft of the driving motor 26 passes through the fixed plate 11 and is fixed on the driving wheel 23, thereby driving the driving wheel 23 to rotate.

[0043] And an adjusting wheel 24 is provided on one side of the driving wheel 23, and the adjusting wheel 24 is provided on the fixed plate 11. In the present application, a synchronous belt 25 is wound around the outer sides of the first pulley 21, the second pulley 22, the driving wheel 23 and the adjusting wheel 24. Under normal conditions, the synchronous belt 25 is not in a completely taut state, and the synchronous belt 25 has a certain elasticity.

[0044] At the same time, a telescopic rod 3 is provided on the outer side of the two groups of support plates 12. The telescopic rod 3 is a prior art that can be telescopic. The telescopic rod 3 is installed at the upper end of the fixed seat 1. The upper end of the telescopic rod 3 is rotatably connected to a detection wheel 31. The height of the detection wheel 31 can be adjusted by the telescopic rod 3, so that the detection wheel 31 can adapt to rotors 5 of different heights. In the present application, a test system is provided on the detection wheel 31. The test system is a prior art, and the balance of the rotation speed of the rotor 5 is tested by the detection wheel 31.

[0045] A slide groove 34 is provided at the upper end of the fixed seat 1, a slider 33 is slidably connected in the slide groove 34, a base 32 is fixedly installed on the upper end of the slider 33, and the base 32 is fixed to the lower end of the telescopic rod 3, so that the telescopic rod 3 can slide in the slide groove 34 through the slider 33;

[0046] Meanwhile, a threaded hole 36 is provided on the slider 33, and a bolt 35 is connected to the inner thread of the threaded hole 36. Therefore, when the bolt 35 is tightened, the bolt 35 will be pressed into the slide groove 34, thereby fixing the slider 33 and the telescopic rod 3 to prevent the detection wheel 31 from shaking and affecting the detection effect.

[0047] Therefore, when testing the rotor 5, the rotor 5 is first placed on the synchronous belt 25. At this time, the gravity of the rotor 5 itself will press the synchronous belt 25 downward, so that the rotor 5 is attached to the synchronous belt 25. At the same time, the shaft of the rotor 5 is placed between the wheels 13 and attached to the detection wheel 31. Then, the drive motor 26 is started to drive the drive wheel 23 to rotate, thereby driving the synchronous belt 25 to transmit, so that the rotor 5 rotates. At this time, the rotation range of the rotor 5 shaft will be detected and recorded by the detection wheel 31. Then, the test system is used to judge whether the vibration range of the rotor 5 shaft is consistent, and weights are added at the inconsistent end until the data are the same.

[0048] like Figure 2-Figure 4 As shown, in order to adapt to rotors 5 of different sizes, an adjusting mechanism 4 is provided between the fixed plate 11 and the adjusting wheel 24, and the adjusting mechanism 4 has an adjusting slot 41 opened on the fixed plate 11, and an adjusting block 42 is slidably connected in the adjusting slot 41. At the same time, the adjusting wheel 24 is mounted on the adjusting block 42, and a cylinder 43 is fixedly mounted on one side of the fixed plate 11, and the output shaft of the cylinder 43 is fixedly mounted on the adjusting block 42. Therefore, starting the cylinder 43 can drive the adjusting block 42 to slide in the adjusting slot 41, thereby adjusting the position of the adjusting wheel 24 to adjust the tension of the synchronous belt 25, so that the synchronous belt 25 can be placed on rotors 5 of different sizes.

[0049] To sum up: when encountering rotors 5 of different sizes, first loosen the bolts 35, then adjust the telescopic rod 3 and the detection wheel 31 outward, then start the cylinder 43 to adjust the position of the adjusting wheel 24, so as to loosen the tension of the synchronous belt 25, then place the rotor 5 to be detected and corrected on the synchronous belt 25, and press the synchronous belt 25 downward by its own gravity to tighten the synchronous belt 25, then push the telescopic rod 3 and the detection wheel 31 toward the rotor 5 until the detection wheel 31 is attached to the rotating shaft of the rotor 5, thereby adapting to rotors 5 of different sizes, improving the flexibility of the correction device, and increasing the working range of the correction device.

For those skilled in the art, the present application may have various modifications and variations.
