[0022] The present invention is described in detail below with reference to the embodiments.

[0023] like Figure 1 As shown, a high-voltage power supply vibration test platform device includes a carrier 1, a rotating body 2, and a base 3.

[0024] like Figure 2 and Figure 3 As shown, the carrier 1 is composed of a platform 11, a universal ball bearing 12, a shock absorbing spring 13 and a limit guide rod 14. The platform 11 is square, and a plurality of holes 111 are processed on the surface to facilitate the fixing of the vibrated object. The limit guide rods 14 are installed at the four corners below, which can be welded or screwed. Each limit guide rod 14 is sleeved with a shock absorbing spring 13, so that when the platform vibrates, it is limited to up and down movement to prevent left and right swinging; three universal ball bearings 12 are evenly installed on a circumference in the middle part of the same side, which can be connected by screws or fixed by welding.

[0025] like Figure 4 and Figure 5 As shown, the rotating body 2 is composed of a vibration slope 21, a rotating table 22, a rotating shaft 23, and a tapered roller bearing 24, wherein the rotating table 22 is a circular steel plate, and the thickness of the steel plate should be appropriately thicker (thickness is 15-20mm) to ensure that it does not deform during vibration impact. Three vibration slopes 21 are evenly welded on the circular steel plate. The cross-section of the vibration slope 21 is trapezoidal, and the slopes on both sides are suitable for not hitting the universal ball bearing during movement. The height is moderate (height is 25mm-45mm). Too low will not have a vibration effect, and too high vibration will cause excessive damage. The bottom of the rotating table 22 is connected to the rotating shaft 23, which can be welded or connected by bolts. The rotating shaft 23 is in a step shape, with a flange at the top, which can be welded to the rotating table 22 or connected by bolts. The second is the shaft, which matches the bearing. The shaft is a transitional shaft, with a diameter slightly smaller than the diameter of the bearing installation part and slightly larger than the lower end diameter. The length is moderate, which makes it easy to install the tapered roller bearing 24 and also increases the torsional strength of the shaft. The shaft at the bottom of the rotating shaft 23 matches the output hole of the reducer, including the length of the shaft, the diameter of the shaft and the keyway.

[0026] The base 3 is in a square shape with an appropriate height. A bearing seat 32 is processed in the middle of the upper surface of the base. There are circular holes 311 at the four corners for assembling the limiting guide rod 14. Support feet 34 are processed at the four corners below the base for easy placement and transportation. A motor reducer 33 is installed at an appropriate position on the side of the base 3.

[0027] The carrier 1 is placed on the rotating table 22 of the rotating body 2 through three universal ball bearings 12, the limiting guide rods 14 on the four corners are placed in the circular holes 311 on the base, and the shock-absorbing springs are placed between the carrier 1 and the rotating body 2 to prevent the two from colliding and damaging the equipment, thus playing a buffering role. During operation, the motor reducer drives the rotating table 22 to rotate, and the three vibration slopes 21 on the rotating table rotate on the same circumferential surface as the rotating table. When it rotates to the universal ball bearing 12 at the bottom of the carrier 1, the trapezoidal surface of the vibration slope 21 realizes the vibration effect on the universal ball bearing, thereby driving the carrier to vibrate up and down, achieving the experimental purpose.

[0028] From the prototype trial production effect, the utility model is reliable and feasible, and the structure is simple and easy to realize.
