Description

Technical Field

[0001] This invention belongs to the technical field of triaxial vibration testing instruments, and specifically relates to a triaxial vibration testing device and method. Background Technology

[0002] A triaxial vibration meter is a precision instrument that can simultaneously measure the vibration signals of an object in three orthogonal directions: X, Y, and Z. It can simultaneously acquire key vibration parameters such as acceleration, velocity, and displacement, and is widely used in fields such as industrial equipment monitoring, fault diagnosis, environmental vibration assessment, and human body vibration measurement.

[0003] Existing triaxial vibration testing instruments have many threaded holes on the table surface used to place products. These holes are used to install mounting rods to fix the products in place. However, during testing, the threaded holes without mounting rods are exposed, causing the bottom area of ​​the product corresponding to the threaded holes to be suspended when the bottom of the product contacts the table surface. This results in the vibration not being fully transmitted to the product, affecting the test results.

[0004] Therefore, it is necessary to invent a triaxial vibration detection device and method to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a triaxial vibration detection device and method to solve the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a triaxial vibration detection device, comprising: A testing station used for triaxial vibration testing; A work surface, set on the testing table, is used to place the product to be tested; Threaded holes are provided on the table surface; A plugging post, threadedly connected inside the threaded hole, is used to plug the threaded hole; A retaining ring, fitted over the outside of the sealing post, is used to restrict the position of the sealing post; The mounting rod can be threaded into the threaded hole, and the mounting rod is used to install a bracket to fix the product. A drive assembly, disposed outside the occlusion post, is used to drive the occlusion post to rotate.

[0007] Furthermore, the driving component includes: A circular shell is fitted over the outside of the sealing post, and the top of the circular shell is rotatably mounted on the bottom of the platform; A torsion spring is sleeved on the outside of the circular shell, and the two ends of the torsion spring are fixedly connected to the circular shell and the platform, respectively. A slider is symmetrically and fixedly installed on the inner side of the circular shell, and a groove is provided on the outer side of the sealing column to cooperate with the slider. The slider is slidably installed in the groove. A rotating component, disposed outside the circular shell, is used to drive the circular shell to rotate.

[0008] Furthermore, the rotating assembly includes: An adsorption plate is attached to the outside of the circular shell; An electromagnet, connected to the bottom of the platform, is used to attract the adsorption plate.

[0009] Furthermore, when the retaining ring abuts against the bottom of the platform, the torsion spring is in a state of torsional deformation.

[0010] Furthermore, the bottom of the mounting rod is provided with a lubrication component, which can lubricate the threaded hole.

[0011] Furthermore, the lubrication assembly includes: The extrusion chamber is located inside the mounting rod; A storage cavity is disposed inside the mounting rod and located above the extrusion cavity; A channel connects the extrusion chamber to the storage chamber; A nozzle is arranged around the outside of the mounting rod, and the nozzle communicates with the extrusion chamber; One-way valves are respectively installed in the channel and the nozzle; Both the extrusion chamber and the storage chamber are filled with lubricating fluid. An extrusion assembly, located at the bottom of the mounting rod, is used to extrude the lubricant from the extrusion chamber.

[0012] Furthermore, the extrusion assembly includes: A stopper plate is disposed inside the extrusion chamber; A spring connects the plug plate to the top wall of the extrusion chamber; A connecting rod is fixedly connected to the bottom of the plug plate, and the bottom of the connecting rod extends to the outside of the extrusion chamber; The pressure plate is rotatably mounted on the bottom of the connecting rod.

[0013] Furthermore, the stiffness coefficient of the torsion spring is greater than that of the spring.

[0014] The method for testing using the triaxial vibration testing device described above includes the following steps: S1. In use, the sealing column is driven to rotate forward by the drive component, so that the sealing column descends along the threaded hole. At this time, the upper part of the threaded hole opens. Then, the mounting rod is connected to the threaded hole, and then the bracket for fixing the product is installed with the mounting rod. S2. After installation, the drive assembly drives the sealing column to reverse, and the sealing column rises along the threaded hole. The sealing column that does not contact the mounting rod can be reset, so that the top is flush with the top of the platform. The sealing column that contacts the mounting rod cannot rise and reset, thus achieving the sealing of all threaded holes that do not have the mounting rod inserted. S3. Subsequently, the product is fixed on the table with the bracket. The testing table vibrates in conjunction with the table, and the vibration is transmitted to the product for testing. The sealing column fills the threaded hole on the table, so that the vibration energy is transmitted to the product more fully and evenly, improving the accuracy of the test results. After the test is completed, the mounting rod is removed, and the drive component continues to drive the sealing column to reverse until it is reset. This allows the sealing column to reset itself after the mounting rod is removed, improving the convenience of operation.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention can seal all threaded holes that are not fitted with mounting rods. By filling the threaded holes on the table with the sealing rod, the vibration energy is transmitted to the product more fully and evenly, improving the accuracy of the test results. After the test is completed, the mounting rod is removed, and the drive assembly continues to drive the sealing rod to reverse until it is reset. This allows the sealing rod to reset itself after the mounting rod is removed, improving the convenience of operation. 2. This invention can lubricate the threaded hole, thus preventing the sealing post from getting stuck when moving along the threaded hole, ensuring the smooth reset of the sealing post, and thus ensuring the sealing of the threaded hole.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides a triaxial vibration detection device, such as... Figures 1 to 4 As shown, it includes: a testing table 1, a table surface 2, a threaded hole, a sealing post 3, a retaining ring 4, a mounting rod 10, and a drive assembly; The testing table 1 is used for triaxial vibration testing. The testing table 1 is a triaxial vibration testing instrument in the prior art. The table surface 2 is set on the testing table 1 and is used to place the product to be tested. The table surface 2 is the table surface on the triaxial vibration testing instrument in the prior art. The threaded hole is set on the table surface 2. The sealing column 3 is threadedly connected to the threaded hole and is used to seal the threaded hole. The top of the sealing column 3 is flush with the top of the table surface 2. The retaining ring 4 is fixedly sleeved on the outside of the sealing column 3 and is used to restrict the position of the sealing column 3. The mounting rod 10 can be threadedly connected to the threaded hole. The mounting rod 10 is used to install the bracket for fixing the product. The lower outer part of the mounting rod 10 is provided with thread 12, which is adapted to the threaded hole. The mounting rod 10 is the mounting rod on the triaxial vibration testing instrument in the prior art used to connect the bracket for fixing the product to the table surface 2. The driving component is set on the outside of the sealing column 3 and is used to drive the sealing column 3 to rotate.

[0019] In use, the sealing post 3 is driven to rotate forward by the drive assembly, causing it to descend along the threaded hole. At this point, the upper part of the threaded hole opens, allowing the mounting rod 10 to connect to the threaded hole. The bracket for fixing the product is then installed using the mounting rod 10. After installation, the drive assembly drives the sealing post 3 to rotate in reverse, causing it to rise along the threaded hole. Sealing posts 3 that are not in contact with the mounting rod 10 can return to their original position, making their tops flush with the top of the platform 2. Sealing posts 3 that are in contact with the mounting rod 10 cannot rise to their original position, ultimately achieving the desired result without the mounting rod inserted. All threaded holes of mounting rod 10 are sealed. Subsequently, the product is fixed on the table 2 with the bracket. The testing table 1 vibrates in conjunction with the table 2, and the vibration is transmitted to the product for testing. The threaded holes on the table 2 are filled by the sealing rod 3, so that the vibration energy is transmitted to the product more fully and evenly, improving the accuracy of the test results. After the test is completed, the mounting rod 10 is removed, and the drive component continues to drive the sealing rod 3 to reverse until it is reset. This allows the sealing rod 3 to reset automatically after the mounting rod 10 is removed, improving the convenience of operation.

[0020] like Figure 2 and Figure 4 As shown, the drive assembly includes: a circular shell 5, a torsion spring 6, a slider 7, and a rotating assembly; The circular shell 5 is fitted outside the sealing column 3. The top of the circular shell 5 is rotatably mounted on the bottom of the platform 2. The torsion spring 6 is fitted outside the circular shell 5. The two ends of the torsion spring 6 are fixedly connected to the circular shell 5 and the platform 2 respectively. The slider 7 is symmetrically fixedly mounted inside the circular shell 5. The outer side of the sealing column 3 is provided with a groove that cooperates with the slider 7. The slider 7 is slidably mounted in the groove. The rotating component is set outside the circular shell 5 and is used to drive the circular shell 5 to rotate.

[0021] The rotating component drives the circular shell 5 to rotate forward. The circular shell 5, together with the slider 7, carries the sealing column 3 to rotate forward. At this time, the torsion spring 6 is torsionally deformed, and the sealing column 3 descends along the threaded hole. The rotating component cancels the drive on the circular shell 5, and the torsion spring 6 carries the circular shell 5 to rotate in reverse. Conversely, it can realize the reverse rotation of the sealing column 3, so that the sealing column 3 rises along the threaded hole to reset.

[0022] like Figure 2 As shown, the rotating assembly includes: an adsorption plate 8 and an electromagnet 9; The adsorption plate 8 is fixedly connected to the outside of the circular shell 5. The adsorption plate 8 is a plate-shaped component that can be magnetically adsorbed. It can be an iron plate, but is not limited to an iron plate. The electromagnet 9 is fixedly connected to the bottom of the table 2 and is used to adsorb the adsorption plate 8. The magnetism generated by the electromagnet 9 when it is energized will not affect the normal operation of the detection table 1.

[0023] When the electromagnet 9 is energized, it becomes magnetic, causing the attraction plate 8 to rotate the circular shell 5 in the forward direction. The circular shell 5 then twists the torsion spring 6, causing it to deform. When the electromagnet 9 is de-energized, the torsion spring 6 returns to its original position, thus causing the circular shell 5 to rotate in the reverse direction and return to its original position.

[0024] like Figure 4 As shown, when the retaining ring 4 contacts the bottom of the platform 2, the torsion spring 6 is in a state of torsional deformation.

[0025] This allows the torsion spring 6 to provide a torque to the sealing post 3, which keeps the top of the sealing post 3 flush with the top of the platform 2.

[0026] like Figure 3 As shown, the bottom of the mounting rod 10 is provided with a lubrication assembly, which can lubricate the threaded hole. The lubrication assembly includes: extrusion chamber 13, storage chamber 14, channel 15, spray hole 16, one-way valve, and extrusion assembly. The extrusion chamber 13 is located inside the mounting rod 10, and the storage chamber 14 is located inside the mounting rod 10 and above the extrusion chamber 13. The channel 15 connects the extrusion chamber 13 and the storage chamber 14. The nozzle 16 is arranged around the outside of the mounting rod 10 and is connected to the extrusion chamber 13. One-way valves are respectively arranged in the channel 15 and the nozzle 16. The extrusion chamber 13 and the storage chamber 14 are both filled with lubricating fluid. The extrusion assembly is located at the bottom of the mounting rod 10 and is used to extrude the lubricating fluid in the extrusion chamber 13 outward.

[0027] When the mounting rod 10 is connected to the threaded hole, the sealing column 3 rises and cooperates with the extrusion assembly to squeeze the lubricant in the extrusion chamber 13 outward. At this time, the one-way valve in the spray hole 16 opens and the one-way valve in the channel 15 closes. The lubricating oil is squeezed into the threaded hole through the spray hole 16 and slides down the threaded hole under the action of gravity to lubricate the inner wall of the threaded hole. When the mounting rod 10 is removed, the lubrication of the inner wall of the threaded hole prevents the sealing column 3 from getting stuck when it moves along the threaded hole, thus ensuring the smooth reset of the sealing column 3.

[0028] like Figure 3 As shown, the extrusion assembly includes: a stopper plate 17, a spring, a connecting rod 18, and a pressure plate 11; The stopper plate 17 is disposed inside the extrusion chamber 13. A spring connects the stopper plate 17 to the top wall of the extrusion chamber 13. The connecting rod 18 is fixedly connected to the bottom of the stopper plate 17. The bottom of the connecting rod 18 extends to the outside of the extrusion chamber 13. The pressure plate 11 is rotatably mounted on the bottom of the connecting rod 18. The outer side of the mounting rod 10 is provided with an oil filling hole communicating with the storage chamber 14. A plunger 19 is provided in the oil filling hole.

[0029] When the sealing column 3 rotates and rises, the top of the sealing column 3 abuts against the pressure plate 11, thereby pushing the pressure plate 11 and the connecting rod 18 and the plug plate 17 to rise, thereby squeezing the lubricating oil in the extrusion chamber 13 outward. At this time, the spring is compressed and deformed, and the pressure plate 11 is rotated to prevent the sealing column 3 from relying on friction to rotate the mounting rod 10 away from the threaded hole. After the mounting rod 10 leaves the threaded hole, the spring carries the plug plate 17 down, and at this time, lubricating oil is drawn into the extrusion chamber 13.

[0030] The stiffness coefficient of torsion spring 6 is greater than that of spring.

[0031] This ensures that when the sealing column 3 rotates and rises, it can squeeze the pressure plate 11, connecting rod 18, and plug plate 17 to compress the spring.

[0032] Working principle: When in use, energizing the electromagnet 9 makes it magnetic, causing the attraction plate 8 to rotate clockwise along with the circular shell 5. The circular shell 5, in conjunction with the slider 7, rotates the sealing column 3 clockwise. At this time, the torsion spring 6 is torsionally deformed, and the sealing column 3 descends along the threaded hole. Finally, the attraction plate 8 and the electromagnet 9 are attracted and fixed, opening the upper part of the threaded hole. The mounting rod 10 is then connected to the threaded hole, and the bracket for fixing the product is installed using the mounting rod 10. After installation, de-energizing the electromagnet 9 causes the torsion spring 6 to reset, thus rotating the circular shell 5 in reverse. Conversely, reversing the current allows the sealing column 3 to rotate in reverse, causing it to rise along the threaded hole. The sealing column 3 that is not in contact with the mounting rod 10 can reset, allowing the top to... The top of the platform 2 is flush with the surface, and the sealing column 3, which is in contact with the mounting rod 10, cannot rise and reset. This ultimately seals all the threaded holes that are not fitted with the mounting rod 10. Subsequently, the product is fixed on the platform 2 with the support bracket. The testing table 1 vibrates in conjunction with the platform 2, and the vibration is transmitted to the product for testing. The sealing column 3 fills the threaded holes on the platform 2, so that the vibration energy is transmitted to the product more fully and evenly, improving the accuracy of the test results. After the test is completed, the mounting rod 10 is removed. The torsion spring 6, together with the round shell 5 and the slider 7, continues to drive the sealing column 3 to reverse until it resets. This allows the sealing column 3 to reset itself after the mounting rod 10 is removed, improving the convenience of operation. When the sealing column 3 rotates and rises, the top of the sealing column 3 abuts against the pressure plate 11, thereby pushing the pressure plate 11 and the connecting rod 18 and the plug plate 17 to rise, thus squeezing the lubricating oil in the extrusion chamber 13 outward. At this time, the spring is compressed and deformed. At this time, the one-way valve in the spray hole 16 opens and the one-way valve in the channel 15 closes. The lubricating oil is squeezed into the threaded hole through the spray hole 16. Under the action of gravity, it slides down along the threaded hole to lubricate the inner wall of the threaded hole. Subsequently, when the mounting rod 10 is removed, the lubrication of the inner wall of the threaded hole prevents the sealing column 3 from getting stuck when it moves along the threaded hole, ensuring the smooth reset of the sealing column 3. After the mounting rod 10 leaves the threaded hole, the spring carries the plug plate 17 down. At this time, lubricating oil is drawn into the extrusion chamber 13. At this time, the one-way valve in the spray hole 16 closes and the one-way valve in the channel 15 opens. The lubricating oil in the storage chamber 14 enters the extrusion chamber 13 through the channel 15 for replenishment.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
