Description

Technical Field

[0001] This utility model relates to the field of vibration testing equipment technology, specifically a vibration testing platform. Background Technology

[0002] A vibration testing platform is a specialized device used to simulate vibration environments and test the vibration resistance of objects (such as mechanical parts, structural components, and electronic equipment). It generates vibrations of different frequencies, amplitudes, and waveforms to verify the reliability, stability, and fatigue life of the tested object under vibration conditions. It is widely used in aerospace, automotive manufacturing, electronic communications, and construction engineering.

This means that some vibration testing platforms can only detect vertical vibration data during vibration tests, and cannot detect horizontal vibration factors. As a result, the vibration test data is not comprehensive and the accuracy of the vibration test data is reduced. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: Referring to 1-5, in this embodiment, a vibration test platform includes: a base 1; a vibration table 2, movably mounted on the base 1, the vibration table 2 being inclined; a fixed platform 3 slidably mounted on the vibration table 2, the fixed platform 3 having a horizontal top surface; a connecting frame 4, fixedly mounted on the bottom end of the vibration table 2; a drive motor 5, fixedly mounted on the base 1; an eccentric wheel 6, driven by the output end of the drive motor 5, the surface of the eccentric wheel 6 always in contact with the surface of the connecting frame 4, and the eccentric wheel 6 being configured to cause the vibration table 2 to vibrate vertically under the drive of the connecting frame 4 when it rotates; and an adjusting rod 7, which is rotated... Placed on the base 1, the other end of the adjusting rod 7 is rotatably set to one side of the fixed platform 3. When the vibration table 2 is set to vibrate in the vertical direction, the adjusting rod 7 drives the fixed platform 3 to vibrate in the horizontal direction. By tilting the vibration table 2, the pressure on the vibration table 2 can be reduced when the adjusting rod 7 pulls the fixed platform 3 to move, making the movement of the fixed platform 3 more convenient and stable. By setting the eccentric wheel 6, the vibration table 2 can vibrate under the drive of the drive motor 5. By setting the adjusting rod 7, the fixed platform 3 can be pushed and pulled in the horizontal direction under the drive of the vibration table 2, realizing the horizontal vibration of the fixed platform 3.

[0022] It also includes: a guide rod 9, symmetrically arranged on the base 1, with the connecting frame 4 slidingly disposed inside the guide rod 9; and a limiting cover 10, fixedly disposed on the top of the guide rod 9, which can guide and position the connecting frame 4 to prevent it from tilting during movement.

[0023] It also includes a return spring 11, which is sleeved on the guide rod 9. The two ends of the return spring 11 abut against the surfaces of the limiting cover 10 and the connecting frame 4, respectively, so that the connecting frame 4 can be reset, so that the connecting frame 4 is always in contact with the surface of the eccentric wheel 6, thereby improving the stability during vibration.

[0024] It also includes: roller 8, which is rotatably mounted on the connecting frame 4. The surface of roller 8 abuts against the surface of eccentric wheel 6, reducing the friction between the connecting frame 4 and eccentric wheel 6 and improving service life.

[0025] It also includes: a T-shaped slide groove 13, which is formed on the vibration table 2; and a T-shaped slide rail 14, which is fixedly set on the fixed table 3. The surface of the T-shaped slide rail 14 slides with the inside of the T-shaped slide groove 13 to improve the stability of the connection and prevent the fixed table 3 from shaking during vibration.

[0026] It also includes: a number of balls 15, which are rotatably mounted on the T-shaped slide rail 14. The balls 15 are evenly distributed along the axial direction of the T-shaped slide rail 14. The surface of the balls 15 rolls into contact with the bottom surface inside the T-shaped slide groove 13 to reduce friction.

[0027] It also includes: four telescopic columns 16, which are fixedly installed on the base 1, with the telescopic ends of the telescopic columns 16 fixedly installed at the bottom of the vibration table 2; and a pad 12, which is fixedly installed on the base 1, with the top of the pad 12 fixedly connected to the surface of the drive motor 5.

[0028] This utility model provides a vibration testing platform, the specific working principle of which is as follows:

[0029] The staff fixed the parts to be tested onto the fixed platform 3, and then started the drive motor 5. The drive motor 5 drove the eccentric wheel 6 to rotate, which caused the eccentric wheel 6 to intermittently push the connecting frame 4 up and down, causing the vibration table 2 to vibrate. During the vibration of the vibration table 2, the adjusting rod 7 pulled the fixed platform 3 to slide back and forth along the surface of the vibration table 2, so that the fixed platform 3 vibrated in the vertical direction and also in the horizontal direction.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
