[0002] As a core component of rotating machinery such as motors, fans, pumps, turbines, and drive shafts, the rotor's dynamic balance accuracy directly determines the stability, noise level, and service life of the entire machine. During machining and assembly, rotors are prone to mass eccentricity and imbalance due to factors such as uneven material composition, machining errors, and assembly deviations. When the rotor rotates at high speed, it generates periodic centrifugal force, causing problems such as equipment vibration, bearing wear, and machine body shaking. In severe cases, this can lead to mechanical failure, equipment downtime, and even safety accidents. Therefore, dynamic balancing tests before rotors leave the factory and after maintenance are essential and critical procedures in the manufacturing and maintenance of rotating machinery.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8 In this embodiment of the invention, a rotor dynamic balancing test device with self-clamping function includes a support frame 1. A test platform 2 is bolted to the upper end of the support frame 1, and an automatic clamping loading frame mechanism 7 is installed at one corner of the upper end of the test platform 2. An automatic clamping test frame mechanism 8 is provided at the upper end of the test platform 2, and a rotating plate 4 is provided above the test platform 2. A pressure wheel 41 is installed on the upper side of the rotating plate 4, a first driven wheel 42 is installed at one end of the side of the rotating plate 4, a second driven wheel 43 is installed at the lower side of the side of the rotating plate 4, and a driving wheel 44 is installed on the upper side of the side of the rotating plate 4. The driving wheel 44 is connected to the first driven wheel 42 and the second driven wheel 43 via a transmission belt 45, and the pressure wheel 41 is located at the upper end of the transmission belt 45.

[0028] More specifically, the automatic clamping loading rack mechanism 7 includes a second motor 71, a second cylinder 72 is mounted on the upper end of the second motor 71, a fixed frame 73 is mounted on the upper end of the second cylinder 72, a third cylinder 74 is bolted inside the fixed frame 73, and a drive frame 75 is mounted on one end of the third cylinder 74; a rotating clamping box mechanism 76 is mounted on the bottom end of the drive frame 75, a third motor 77 is mounted on the upper end of the rotating clamping box mechanism 76, and a clamping block 78 is mounted on the lower end of the rotating clamping box mechanism 76.

[0029] More specifically, the rotating clamping box mechanism 76 includes a fixed box 761. A lifting tube 762 is provided in the middle of the interior of the fixed box 761, and sliding holes 763 are symmetrically opened at the lower front and rear ends of the fixed box 761. A threaded column 764 is movably arranged inside the lifting tube 762. A sliding rod 765 is movably arranged inside the sliding hole 763. A drive frame 766 is connected to the middle of both sides of the lifting tube 762 through a U-shaped seat, and the sliding rod 765 passes through the interior of the drive frame 766. The threaded column 764 passes through the middle of the interior of the fixed box 761.

[0030] Through the above technical solution, when the third motor 77 is working, it drives the threaded column 764 to rotate. Through the threaded connection between the threaded column 764 and the lifting tube 762, the lifting tube 762 rises. When the lifting tube 762 rises, it works with the U-shaped frame to drive the frame 766, causing the frame 766 to rotate. When the frame 766 rotates, it drives the clamping block 78 to move outward. Then, in conjunction with the second motor 71, the second cylinder 72, and the third cylinder 74, the clamping block 78 is moved to the outside of the rotor. Then, the third motor 77 reverses its operation and drives the clamping block 78 to move closer to the center position, thus clamping the rotor and facilitating loading and unloading operations.

[0031] More specifically, the automatic clamping test rack mechanism 8 includes a test bracket 81, with a base 82 penetrating through the bottom end of the test bracket 81; a connecting seat 83 is installed on the upper part of one end of the test bracket 81, and a clamping groove 84 is opened in the middle of the upper end of the test bracket 81; a pressing strip 85 is connected to the upper end of the connecting seat 83 by a pin, and a pressing block 86 is provided at the bottom end of the pressing strip 85.

[0032] With the above technical solution, when loading and unloading the rotor, the two ends of the rotor are inserted into the inside of the clamping groove 84, and the two ends of the rotor are pressed and stabilized by the pressing block 86 during the testing process to prevent the rotor from shaking and affecting the test results.

[0033] More specifically, a first cylinder 3 is installed on one side of the bottom of the test bench 2, and a first motor 5 is bolted to the side of the rotating plate 4; a connecting frame 6 is bolted to the bottom of the rotating plate 4, a protective plate 9 is installed on the lower part of one side of the rotating plate 4, and a connecting block 10 is provided below the protective plate 9.

[0034] More specifically, the third motor 77 is bolted to the upper middle position of the fixed box 761; the upper end of the threaded column 764 is connected to the output shaft of the third motor 77 through a coupling; the drive frame 766 is configured as an inverted L-shape, and the bottom bolt of the drive frame 766 is installed at the upper middle position of the clamping block 78; the upper bolt of the fixed box 761 is installed at the bottom end of the drive frame 75.

[0035] More specifically, the second motor 71 is bolted to one corner of the bottom of the test bench 2, and the second cylinder 72 is located at one corner of the top of the test bench 2.

[0036] More specifically, the test bracket 81 is symmetrically installed on one side of the upper end of the test bench 2.

[0037] More specifically, the drive wheel 44 is mounted on the outer wall of the output shaft of the first motor 5.

[0038] More specifically, the first cylinder 3 penetrates the test bench 2, and the upper end of the first cylinder 3 is installed inside the connecting frame 6 through a T-shaped connection. The protective plate 9 is set in an L-shape, and the bottom end of the protective plate 9 is connected to the upper end of the connecting block 10 through an inverted T-shaped rod.

[0039] The working principle of this invention is as follows: When in use, the rotor is clamped by the clamping block 78, and the rotor is moved by the cooperation of the second motor 71, the second cylinder 72 and the third cylinder 74. The rotor is moved to the test bracket 81 so that both ends of the rotor pass through the clamping slots 84. Then, the first motor 5 is controlled to start working, driving the drive wheel 44 to rotate. The drive belt 45 drives the first driven wheel 42 and the second driven wheel 43 to rotate respectively. The first cylinder 3 pushes the connecting frame 6, causing the connecting frame 6 to drive the rotating plate 4 to rotate, and the drive belt 45 to contact the upper end of the rotor, thus realizing the rotor detection work. During the testing process, the third motor 77 drives the threaded column 764 to rotate. Through the threaded connection between the threaded column 764 and the lifting tube 762, the lifting tube 762 rises. As the lifting tube 762 rises, it works in conjunction with the U-shaped frame to drive the frame 766, causing the frame 766 to rotate. When the frame 766 rotates, it drives the clamping block 78 to move outward. Then, in conjunction with the second motor 71, the second cylinder 72, and the third cylinder 74, the clamping block 78 is moved to the outside of the rotor. The third motor 77 then reverses its operation, causing the clamping block 78 to move towards the center position, thus clamping the rotor for easy loading and unloading. During the testing process, when loading and unloading the rotor, the two ends of the rotor are inserted into the clamping groove 84, and the two ends of the rotor are pressed and stabilized by the pressing block 86 during the testing process to prevent the rotor from shaking and affecting the test results.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
