Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A rapid dynamic balancing calibration platform for a three-lobe rotor includes a base 1. A motor 3 is located on the left side of the top of the base 1. The output end of the motor 3 passes through a support plate 2 and is fixedly connected to a rotating seat 4. A lead screw 5 is rotatably connected to the left side of the inner cavity of the rotating seat 4. A worm gear 6 is fixedly sleeved on the left side of the outer side of the lead screw 5. A worm 7 adapted to the worm gear 6 is rotatably connected to the bottom of the inner cavity of the rotating seat 4. The right side of the lead screw 5 movably passes through the rotating seat 4. A movable plate 10 is screwed to the right side of the outer side of the rotating seat 4. A connecting rod 11 is rotatably connected to the outer side of the movable plate 10. A clamping plate 12 is rotatably connected to one side of the connecting rod 11. A clamping block 13 is fixedly installed on one side of the clamping plate 12. Limiting frames 17 are fixedly installed on the left and right sides and the front and rear sides of the base 1. A screw 18 is provided on the top of the limiting frame 17. The bottom of the screw 18 is threaded through the limiting frame 17 and rotatably connected to a foot pad 19.

[0021] In this embodiment, there are four sets of clamping plates 12, which are arranged in a circular array. The left side of the clamping plates 12 extends into the interior of the rotating seat 4. The right side of the rotating seat 4 is provided with a limiting groove 15 that matches the clamping plates 12. Limiting rods 16 are fixedly installed at the top and bottom of the right side of the rotating seat 4. The right side of the limiting rod 16 movably passes through the moving plate 10 and is fixedly connected to the vertical plate 9. The right side of the lead screw 5 is rotatably connected to the left side of the vertical plate 9. A telescopic rod 14 is fixedly installed on the outside of the vertical plate 9. One side of the telescopic rod 14 is fixedly connected to one side of the clamping plate 12. Through the mutual cooperation of the limiting groove 15 and the telescopic rod 14, the clamping plates 12 can be limited, which improves the movement stability of the clamping plates 12.

[0022] In this embodiment, a support frame 20 is fixedly installed on the rear side of the top of the base 1, a sensor 21 is fixedly installed on the front side of the support frame 20, and a display module 22 is fixedly installed on the right side of the front side of the support frame 20. The output end of the sensor 21 is electrically connected to the input end of the display module 22. A support plate 2 is fixedly installed on the left side of the top of the base 1, and a motor 3 is fixedly installed on the left side of the support plate 2. The top of the worm gear 7 moves through the rotating seat 4 and is fixedly connected to a handwheel 8. The handwheel 8 allows the operator to hold the worm gear 7 for easy rotation.

[0023] In this embodiment, during use, the screw 18 is rotated forward, which, through its interaction with the limiting frame 17, causes the foot pad 19 to move downward, thus leveling the base 1. The three-lobe rotor is then placed inside the clamping block 13. The handwheel 8 is rotated forward, causing the worm 7 to rotate, which in turn causes the worm wheel 6 to rotate, which in turn causes the lead screw 5 to rotate. The lead screw 5 causes the connected movable plate 10 to move to the left. The movable plate 10, through its interaction with the connecting rod 11, causes the clamping plates 12 to move closer together, which in turn causes the clamping blocks 13 to move closer together, clamping and limiting the three-lobe rotor. Then, the motor 3, sensor 21, and display module 22 are started by an external controller. The motor 3 rotates forward, causing the three-lobe rotor to rotate through the rotating seat 4. The sensor 21 performs dynamic balance detection on the three-lobe rotor, and the results are analyzed, processed, and displayed by the display module 22.
