Description

Technical Field

[0001] This invention relates to the field of vibration table technology, specifically to an electromagnetic vibration table system. Background Technology

[0002] Electromagnetic vibration tables are mainly used to test the shock resistance of products and evaluate the stability of product performance. The working principle of an electromagnetic vibration table is that a current-carrying conductor moves under the action of electromagnetic force in a magnetic field. When an alternating current signal passes through the moving coil in the magnetic circuit of the electromagnetic vibration table, an excitation force is generated to produce vibration in the magnetic circuit. It is mainly used in industries such as defense, aviation, aerospace, communications, electronics, automobiles, and home appliances.

[0003] The working principle of an electromagnetic vibration table is as follows: the moving part of the table body, the moving coil, will move when current flows through it. According to Fleming's left-hand rule, the current-carrying coil in a constant magnetic field (generated by the excitation coil of the vibration table body) will move, driving the moving coil and the table surface to move, thereby generating an excitation force. Therefore, electromagnetic vibration tables generally need to be used with a power supply and a computer to facilitate the acquisition of test data. However, existing electromagnetic vibration tables are not convenient to move, have many accessories, require wiring during movement, are inconvenient to operate, and have a relatively simple vibration mode and narrow testing range.

[0030] Please see Figures 1-5 This invention provides a technical solution: an electromagnetic vibration table system, including a movable base plate 1 and a vibration table body 2 mounted on the outside of the movable base plate 1. A mounting frame 3 is mounted on the bottom surface of the movable base plate 1, and a movable wheel 4 is movably mounted on the outer surface of the mounting frame 3. The movable wheel 4 drives the movable base plate 1 to move, thereby moving the vibration table body 2 to the location to be tested. An auxiliary mechanism is mounted on the top surface of the movable base plate 1. The auxiliary mechanism is used to store accessories used in the operation of the vibration table. A moving mechanism is mounted on the top surface of the movable base plate 1 on one side of the auxiliary mechanism. One side surface of the vibration table body 2 is connected to the moving mechanism. The moving mechanism is used to move the vibration table body 2. A spatial vibration mechanism is movably mounted on the top surface of the vibration table body 2. The spatial vibration mechanism is used to enhance the vibration test effect.

[0031] Specifically, the auxiliary mechanism includes an equipment bracket and a power supply box 5. The equipment bracket is installed on the top surface of the movable base plate 1, and the power supply box 5 is installed inside the equipment bracket. The vibration table body 2 is electrically connected to the power supply box 5.

[0032] Furthermore, the equipment support includes vertical plates 6 and horizontal mounting plates 7. The two vertical plates 6 are fixedly mounted on the top surface of the movable base plate 1, and the horizontal mounting plate 7 is mounted on the top surface of the two vertical plates 6. A placement groove 8 is opened on the top surface of the horizontal mounting plate 7. Horizontal support shafts 9 are mounted on the opposite sides of the two vertical plates 6. The power supply box 5 is installed between the vertical plates 6 below the horizontal support shaft 9. The spatial vibration mechanism is installed on the top surface of the horizontal support shaft 9. The laptop is placed in the placement groove 8 and electrically connected to the vibration table body 2 to acquire detection data.

[0033] Furthermore, the moving mechanism includes a drive assembly and a connector. The drive assembly is mounted on the top surface of the moving base plate 1. One side of the connector is mounted on the outer surface of the drive assembly, and the other side of the connector is mounted on one side surface of the vibration table body 2. The drive assembly includes a hydraulic pump 10 and a telescopic connecting shaft 11. The hydraulic pump 10 is mounted on the top surface of the moving base plate 1, and the telescopic connecting shaft 11 is mounted on the outer surface of the output end of the hydraulic pump 10. An inclined plate 12 is mounted on the top surface of the moving base plate 1. The hydraulic pump 10 drives the telescopic connecting shaft 11 to extend, thereby driving the connector to move along the inclined plate 12, moving the vibration table body 2 to one side of the moving base plate 1, thereby placing the vibration table body 2 at the fixed position.

[0034] Furthermore, the connector includes a connector body 13 and a connecting plate 14 mounted on the top surface of the connector body 13. One side surface of the connector is connected to one side surface of the vibration table body 2, and one side surface of the connecting plate 14 is connected to the end surface of the telescopic connecting shaft 11. One side surface of the connector body 13 is provided with a contact slope 15, which is in active contact with one side surface of the inclined plate 12.

[0035] Furthermore, the spatial vibration mechanism includes a fixed housing 16 and vibration components. A test platform 27 is installed on the top surface of the vibration table body 2. The fixed housing 16 is installed on the outside of the test platform 27. The test platform 27 is in movable contact with the inner wall of the fixed housing 16. A limit component is installed on the outer surface of the fixed housing 16. Several vibration components are installed on the inner wall of the fixed housing 16. The product to be tested is placed on the test platform 27, and then the surface of the fixed housing 16 is grasped and the fixed housing 16 is removed from the horizontal support shaft 9.

[0036] Furthermore, the limiting assembly includes an adjusting shaft 17 and an inclined support plate 18. The adjusting shaft 17 is movably mounted on the outer two sides of the fixed housing 16. One side surface of the inclined support plate 18 is mounted on the outer side surface of the adjusting shaft 17, and the other side surface of the inclined support plate 18 is mounted with a limiting long shaft 19. A limiting long groove 20 is formed on the top surface of the vibration table body 2. The limiting long shaft 19 and the limiting long groove 20 are used in conjunction to rotate the adjusting shaft 17 on both sides of the fixed housing 16, so that the inclined support plate 18 forms an inclined angle, thereby inserting the limiting long shaft 19 into the limiting long groove 20, and fitting the fixed housing 16 onto the outside of the test table surface 27.

[0037] Furthermore, the vibration assembly includes a connecting spring 21 and a first mounting plate 22. One end of the connecting spring 21 is mounted on the inner wall of the fixed housing 16, and the first mounting plate 22 is mounted on the other end surface of the connecting spring 21. A second mounting plate 23 is movably mounted on the top surface of the first mounting plate 22. Both the outer surfaces of the first mounting plate 22 and the second mounting plate 23 are equipped with striking components. According to the size of the test product, the relative position between the second mounting plate 23 and the first mounting plate 22 is adjusted. Then, the angle of the connecting shaft 24 on the second mounting plate 23 is adjusted so that the vibrating ball 26 on the second mounting plate 23 can contact the surface of the product to be tested. The tilt angle of the transmission support shaft 25 on the first mounting plate 22 is further adjusted so that the vibrating ball 26 on the first mounting plate 22 can contact the test platform 27.

[0038] Furthermore, the striking assembly includes a connecting shaft 24 and a transmission support shaft 25. The connecting shaft 24 is movably mounted on the outer surfaces of the first mounting plate 22 and the second mounting plate 23, respectively. Several transmission support shafts 25 are mounted on the outer surfaces of the connecting shaft 24. Vibrating balls 26 are mounted on the end surfaces of the transmission support shafts 25. The test platform 27 is controlled by the control system to perform vibration testing. At the same time, the vibrating balls 26 on the first mounting plate 22 vibrate synchronously, transmitting the vibration to the vibrating balls 26 on the second mounting plate 23. Thus, the vibrating balls 26 on the second mounting plate 23 strike and vibrate the side of the product under test, achieving a three-dimensional and comprehensive vibration effect, enhancing the test effect, and improving the comprehensiveness of product testing.

[0039] During use (operation), the moving base plate 1 is moved by the moving wheel 4, thereby moving the vibration table body 2 to the location to be tested. Then, the hydraulic pump 10 drives the telescopic connecting shaft 11 to extend, thereby moving the connecting body 13 along the inclined panel 12, moving the vibration table body 2 to one side of the moving base plate 1, thereby placing the vibration table body 2 at the fixed location. The laptop is placed in the placement slot 8 and electrically connected to the vibration table body 2 to acquire test data.

[0040] Place the product to be tested on the test platform 27, then hold the surface of the fixed housing 16 and remove the fixed housing 16 from the horizontal support shaft 9. According to the size of the product to be tested, adjust the relative position between the second mounting plate 23 and the first mounting plate 22. Then adjust the angle of the connecting shaft 24 on the second mounting plate 23 so that the vibrating ball 26 on the second mounting plate 23 can contact the surface of the product to be tested. Further adjust the tilt angle of the transmission support shaft 25 on the first mounting plate 22 so that the vibrating ball 26 on the first mounting plate 22 can contact the test platform 27.

[0041] Then, the adjusting shafts 17 on both sides of the fixed housing 16 are rotated so that the inclined support plate 18 forms an inclined angle, thereby inserting the limiting long shaft 19 into the limiting long groove 20. The fixed housing 16 is then fitted onto the outside of the test platform 27. The test platform 27 is controlled by the control system to perform vibration testing. At the same time, the vibrating ball 26 on the first mounting plate 22 vibrates synchronously, transmitting the vibration to the vibrating ball 26 on the second mounting plate 23. Thus, the vibrating ball 26 on the second mounting plate 23 strikes and vibrates the side of the product under test, achieving a three-dimensional and comprehensive vibration effect, enhancing the test effect and improving the comprehensiveness of product testing.
