Description

Technical Field

[0001] The invention relates to the technical field of dynamic balancing, and in particular to a performance detection device for an electric roller. Background Art

[0002] An invention patent with application number 202410004445.0 discloses a dynamic balancing test device for a permanent magnet synchronous frequency conversion integrated electric drum, and specifically discloses the technical solution that "when the drum rotates, the internal magnetic poles and the detection permanent magnet block will undergo two actions of attraction and repulsion. When the magnetic steel is opposite to the detection permanent magnet block, the magnetism is maximum. At this time, the attraction or repulsion reaches the highest value. After being processed by the control terminal, a time displacement icon is generated. At this time, the graph curve has multiple peaks and troughs, and the time intervals between the peaks and troughs are the same, which indicates a uniform distribution, and the time interval error indicates a distribution error."

[0003] Although the application measures the distribution error state of the magnetic steel inside the electric drum by detecting the magnetic attraction and repulsion between the permanent magnet block and the magnetic steel inside the electric drum, the imbalance factors when the electric drum rotates are not only the uneven distribution of the internal magnetic poles, but also the uneven distribution of the internal mass, blank defects, errors in processing and assembly, etc. Only detecting the distribution of the magnetic poles inside the electric drum cannot fully indicate the dynamic balance performance of the electric drum.

[0055] When the outer driving clamping claw 2022 is in contact with the outer shaft head 102 , the axial guide column 205 is in contact with the end surface of the roller body 101 at the same time.

[0056] like Figure 1 to Figure 12 As shown, the self-driving three-jaw chuck 5 includes a self-driving chuck 501 and a self-driving jaw 502 . The self-driving chuck 501 is fixed on the self-driving seat 4 , and the self-driving jaw 502 is slidably disposed on the self-driving chuck 501 . The self-driving jaw 502 is abutted against the outer shaft head 102 .

[0057] like Figure 1 to Figure 12 As shown, the external drive positioning assembly 2, the self-drive seat 4 and the self-drive three-jaw chuck 5 are all symmetrically provided with two groups relative to the axial mid-section of the drum body 101;

[0058] An external drive assembly 3 is provided on the base 6, and the external drive assembly 3 includes an external drive motor 301, a worm 302, a worm wheel 303 and a connecting ring 304. The external drive motor 301 is fixed on the base 6, the worm 302 is fixed on the output end of the external drive motor 301, the worm wheel 303 is meshingly connected with the worm 302, and the connecting ring 304 is fixed on the worm wheel 303, and the connecting ring 304 is fixedly connected to the inner ring of a bearing seat 201.

[0059] like Figure 1 to Figure 12As shown, the base 6 is provided with an electric trolley 9 which slides along the axial direction of the roller body 101, and the electric trolley 9 is fixedly provided with an approach electric push rod 10 and an approach electric push rod 2 11, the approach electric push rod 10 is fixedly connected to the indicating platform 701, and the approach electric push rod 2 11 is fixedly provided with a roundness meter 12, and the detection head of the roundness meter 12 is fitted on the roller body 101.

[0060] like Figure 1 to Figure 12 As shown, the roundness meter 12 is connected to the micro-motion electric push rod 801 by signal, and the micro-motion electric push rod 801 is extended and retracted according to the roundness change of the roller body 101 measured by the roundness meter 12, so that the contact force between the closed belt 805 and the outer circumference of the roller body 101 tends to be constant.

[0061] like Figure 1 to Figure 12 As shown, the edge sound indication component 7 also includes a sound insulation cover 706 , which is fixed on the indication platform 701 , and the sound level meter 705 is located in the sound insulation cover 706 .

[0062] like Figure 1 to Figure 12 As shown, the micro-touch sealing unit 8 also includes two lubricating grease blocks 807 . The two lubricating grease blocks 807 are both fixedly disposed on the indicating platform 701 . The two lubricating grease blocks 807 are respectively fitted and connected to the two sealing belts 805 .

[0063] When in use, the roller body 101 and the outer shaft head 102 are first positioned using the external drive positioning assembly 2, and the roller body 101 and the outer shaft head 102 are driven by the external drive assembly 3 to rotate at a constant speed. When the roller body 101 and the outer shaft head 102 rotate, the detection head of the roundness meter 12 maintains contact with the roller body 101, and detects and records the roundness of the roller body 101;

[0064] Subsequently, the positioning relationship between the external drive positioning component 2 and the roller assembly 1 is released, and then the self-driving seat 4 and the self-driving three-jaw chuck 5 are used to position the external shaft head 102;

[0065] The approaching electric push rod 2 11 is retracted to make the roundness meter 12 away from the drum body 101, and the approaching electric push rod 1 10 is extended to make the edge sound indicating assembly 7 close to the drum body 101;

[0066] The power cord 103 is energized, and the drum assembly 1 is controlled to rotate. At this time, the edge sound indicator component 7 detects and records the dynamic balance performance of the drum body 101.

[0067] The working principle of the edge sound indicator assembly 7 is as follows: the air pump 702 and the air outlet nozzle 703 eject airflow at a constant speed, and the airflow goes down through the airflow channel surrounded by the drum body 101, the indicator platform 701, the contour plate 806 and the closed belt 805, and enters the air inlet of the indicator whistle 704. The airflow produces an edge sound effect in the indicator whistle 704 and emits a whistle, and the sound level meter 705 records the volume change of the whistle;

[0068] When the drum assembly 1 rotates, the drum assembly 1 vibrates periodically due to uneven distribution of internal magnetic poles, uneven distribution of internal mass, defects in the blank, errors in processing and assembly, etc., so that the outer circumferential surface of the drum body 101 has a periodic property of approaching and moving away from the ideal outer circumferential surface, that is, the width of the air flow channel between the air outlet nozzle 703 and the indicator whistle 704 will change periodically;

[0069] When the air pump 702 sprays a constant airflow, the closer the distance between the drum assembly 1 and the indicating platform 701 is, the narrower the airflow channel is, the faster the airflow speed entering the indicating whistle 704 is, the faster the sound wave vibration speed of the whistle is and the larger the sound wave amplitude is, and the louder the whistle volume detected by the sound level meter 705 is.

[0070] The working principle of the micro-touch sealing unit 8 is as follows: the sealing motor 803 and the sealing pulley 804 rotate, so that the sealing belt 805 attached to the roller body 101 maintains the same linear speed as the roller body 101, and the block grease 807 makes the sealing belt 805 have a smooth outer contact surface, and on the basis of maintaining the integrity of the air flow channel between the sealing belt 805 and the profiling plate 806, the adverse effect of the contact between the sealing belt 805 and the roller body 101 on the dynamic balance performance detection is reduced;

[0071] During the dynamic balancing performance test, the micro-motion electric push rod 801 is extended and retracted according to the roundness change previously measured by the roundness meter 12. The extension and retraction action of the micro-motion electric push rod 801 drives the closed motor 803, the closed pulley 804, the contour plate 806 and the closed belt 805 to move horizontally through the micro-motion connecting component 802, thereby compensating for the circular runout error of the outer cylindrical surface of the roller body 101, so that a constant contact force is maintained between the closed belt 805 and the roller body 101.

[0072] The working principle of the external drive positioning assembly 2 is as follows: when the external drive three-jaw chuck 202 is adjusted so that the external drive clamping claw 2022 moves toward the center of the external drive chuck 2021, the axial guide column 205 connected to the external drive clamping claw 2022 slides through and moves synchronously toward the center of the external drive chuck 2021, and at the same time, the track ball 204 fixedly connected to the axial guide column 205 moves in the axial constraint rail 203 and enters the inner inclined rail 2032 from the edge flat rail 2031;

[0073] When the outer driving clamping claw 2022 is pressed against the outer shaft head 102 , the rail ball 204 moves to the end of the inner inclined rail 2032 and makes the axial guide column 205 press against the end surface of the roller body 101 .

[0074] The working principle of the external drive component 3 is as follows: after the external drive positioning component 2 locks and supports the roller body 101 and the external shaft head 102, the external drive motor 301 drives the connecting ring 304 to rotate through the meshing relationship between the worm 302 and the worm wheel 303, thereby causing the inner ring of the bearing seat 201, the external drive three-jaw chuck 202, the roller body 101 and the external shaft head 102 to rotate synchronously.

[0075] The working principle of the self-driving seat 4 and the self-driving three-jaw chuck 5 is: adjust the self-driving three-jaw chuck 5 to move the self-driving jaws 502 toward the center of the self-driving chuck 501 until the self-driving jaws 502 lock the outer shaft head 102.

[0076] The electric trolley 9 slides on the base 6 along the axial direction of the drum body 101, thereby adjusting the positions of the roundness meter 12 and the edge sound indicator assembly 7 relative to the drum body 101, so as to perform dynamic balancing detection on multiple areas on the outer circumference of the drum body 101.

[0077] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
