The vibration mode of vibration equipment is particularly important. Current vibration equipment uses a single vibration mode, primarily horizontal or triaxial X, Y, and Z vibration. These modes offer unsatisfactory results, poor stability, and low safety. Therefore, a new technical solution is urgently needed to address these issues. Summary of the Invention

The outer ring of the platform bearing is fixed on the platform seat, and the inner ring of the platform bearing is connected to the top end of the main shaft. The top surface of the main shaft is not horizontal. After the inner ring and outer ring of the platform bearing are fastened, the overall cross-section of the platform bearing is not horizontal, and the platform bearing drives the platform seat to be non-horizontal.

At the same time, each damping pillar is also mounted with two upper and lower damping springs. The two damping springs clamp the platform seat in the middle. A damping adjustment nut is provided on the top of the damping pillar. The elasticity of the damping spring is adjusted by the damping adjustment nut, thereby adjusting the vibration amplitude of the platform seat, and at the same time absorbing the impact and harmonics generated by the unbalanced rotation of the main shaft.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 5 As shown, the three-dimensional vector vibration device of the present invention includes a bottom support device 1, a power device 2, a platform device 3, and a main shaft 4 driven to rotate by the power device 2. The bottom support device 1 includes a square base plate 11 located on the ground. The power device 2 is placed on the base plate 11. A frame-like frame 12 is fixed upward in the middle of the base plate 11. Columnar damping struts 14 are respectively installed at the four corners of the base plate 11. The top ends of the damping struts 14 are connected to the platform device 3. The main shaft 4 is fixed above the power device 2 by the frame 12, passes through the frame 12, and is inserted into the platform device 3. The platform device 3 is vibrated by the rotation of the main shaft 4.

[0020] like Figure 2 and Figure 3 As shown, the power device 2 includes a motor 21 fixed on the base 11, a gear box 22 connected to the motor 21, a coupling 23 connected above the gear box 22, and the main shaft 4 is connected above the coupling 23.

[0021] like Figure 3 As shown, the frame 12 is a cubic frame as a whole, and the top surface of the frame 12 is a plate-shaped machine base 13. The main shaft 4 passes through the machine base 13 and is fixed by the machine base 13 so that it cannot swing. A main shaft bearing 41 is provided between the main shaft 4 and the machine base 13 to enable the main shaft 4 to rotate in the machine base 13. The outer ring of the main shaft bearing 41 is fixed to the machine base 13 by bolts, and the inner ring is fixedly connected to the middle part of the main shaft 4 by bolts. The cross section of the main shaft bearing 41 is horizontal.

[0022] like Figure 3 and Figure 5 As shown, the platform device 3 includes a square plate-shaped platform base 31 supported by damping struts 14. A work platform 32 is located above the platform base 31. The work platform 32 has at least four regularly distributed threaded holes 321, which are used to secure tooling, fixtures, or products. The platform base 31 has holes at its four corners, which fit over the tops of the four damping struts 14. Each damping strut 14 also has two damping springs 33 mounted on top and below. These two damping springs 33 clamp the platform base 31 in place, buffering the mechanical shock and harmonics generated by the unbalanced rotation of the spindle 4. A damping adjustment nut 34 is located at the top of the damping strut 14. This nut adjusts the elasticity of the damping spring 33, thereby adjusting the vibration amplitude of the platform base 31.

[0023] like Figure 2 and Figure 4 As shown, the top of the spindle 4 is inserted upwardly into the middle of the platform seat 31, with a platform bearing 42 positioned between the spindle 4 and the platform seat 31. The outer ring of the platform bearing 42 is bolted to the platform seat 31, while the inner ring of the platform bearing 42 is bolted to the spindle 24. The platform bearing 42 is sturdy and stable. The top surface of the spindle 4 is not horizontal. After the inner ring of the platform bearing 42 is connected to the spindle 4, the overall cross-section of the platform bearing 42 forms an angle with the horizontal plane, preferably 1°. As the spindle 4 rotates, the platform seat 31 is fixed and prevented from rotating by the damping strut 14. Therefore, the non-horizontal top surface of the spindle 4 causes vibration. Adjusting the damping adjustment nut 34 adjusts the elasticity of the damping spring, thereby adjusting the amplitude of the platform seat 31's vibration.

[0024] The main shaft bearing 41 and the platform bearing 42 are preferably bidirectional thrust angular contact ball bearings, which have the advantages of large load, fast speed, and can simultaneously bear the combined load of radial and axial loads, limiting the axial displacement of the shaft in both directions.
