Embodiment 1

[0029] refer to Figure 1-4

[0030] The vibration time-effect vibration level amplifying device is composed of an upper supporting platform 1 for installing workpieces, a lower chassis 3 fixed on the vibrating table surface 4 of the vibrating table, and a connecting rod 2 connecting the upper supporting platform 1 and the lower chassis 3. The upper end of the rod 2 is affixed to the upper pallet 1, and the lower end is affixed to the lower chassis 3. The cross-sectional area of ​​the connecting rod 2 is smaller than the cross-sectional area of ​​the upper pallet 1, and the cross-sectional area of ​​the connecting rod 2 The area is smaller than the cross-sectional area of ​​the lower chassis 3 described above.

[0031] The upper pallet 1, the connecting rod 2 and the lower chassis 3 are integrally formed.

[0032] The upper pallet 1 and the lower chassis 3 are both symmetrical figures, the centroids of the upper pallet 1 and the lower chassis 3 coincide with the symmetrical ...

Embodiment 2

[0051]The difference between this embodiment and the first embodiment is that the connecting rod 2 is fixedly connected to the upper pallet 1 and the lower chassis 3 respectively through fasteners. The rest are the same.

[0052] The connecting rod, the upper support platform and the lower chassis are connected by fasteners, and the three parts can be processed separately, which is convenient for processing and low in processing cost.

Abstract

The invention relates to a vibratory stress relief vibration level amplifying device which consists of an upper supporting table, a lower base plate fixed and a connecting rod, wherein the upper supporting table is used for installing a workpiece; the lower base plate is fixed on an exciting vibration table top of a vibration table; the connecting rod is used for connecting the upper supporting table and the lower base plate; and the cross-sectional area of the connecting rod not only is smaller than that of the upper supporting table, but also is smaller than that of the lower base plate. The vibratory stress relief vibration level amplifying device has the beneficial effects that in the resonance, the vibration level of the exciting vibration table top of the vibration table can be remarkably amplified, the effects of improving the vibratory stress relief and eliminating the residual stress can be realized, the structure is simple and practical, and the operation is convenient.

Description

technical field [0001] The invention relates to a vibration time-effect vibration level amplification device. technical background [0002] The low-frequency sub-resonance aging technology searches for the natural frequency of the workpiece by sweeping the frequency. However, due to the limited speed of the motor, when the natural frequency of the workpiece exceeds the frequency range of the exciter, the low-frequency sub-resonance aging cannot effectively age the workpiece. At present, the high-frequency vibration aging technology based on the vibration table has pointed out the direction for the aging treatment of small workpieces with high natural frequencies, but the output vibration level of the high-frequency vibration table is small, and it is difficult to provide sufficient dynamic stress for the workpiece. Therefore, this paper The invention designs a vibration aging vibration level amplification device, which can significantly amplify the vibration level of the vib...
