Description

Technical Field

[0001] The invention relates to the field of vibration aging technology, and in particular to a small-size component clamping device for a high-frequency vibration aging system. Background Art

[0002] High-frequency vibration aging technology has a series of advantages such as good treatment effect, fast and convenient, low energy consumption, short processing time, and low environmental pollution. It has been widely used in various processes of mechanical processing and manufacturing, and has become a highly regarded energy-saving and environmentally friendly residual stress elimination technology. In the high-frequency vibration aging process, it is necessary to clamp the small-sized components on the working platform of the high-frequency vibration energy amplification device, and use vibration to eliminate residual stress on the small-sized components. Due to the high natural frequency of small-sized components, the types of available optional fixtures are limited. "High-frequency vibration aging system and method for eliminating residual stress of small-sized components" (patent number: ZL201410037981.7) discloses a high-frequency vibration aging system for eliminating residual stress of small-sized components and a high-frequency vibration aging method adapted to the system. In the patent, small-sized components are clamped on the upper support table of the vibration level amplification device through a U-shaped pressing block device, and the small-sized components are subjected to high-frequency vibration aging treatment at the excitation frequency with the maximum ratio of the output vibration level of the vibration level amplification device to the output vibration level of the vibration table, which can achieve the purpose of eliminating residual stress of small-sized components. However, in this patent, the small-sized components are directly and rigidly fixed on the upper support table, which makes it difficult for the small-sized components to vibrate according to their vibration mode shape, reducing the effect of high-frequency vibration aging in eliminating the residual stress of small-sized components. In order to solve the above problems, the present invention proposes a small-sized component clamping device for a high-frequency vibration aging system. The clamping device proposed in the present invention has the advantage of being able to make small-sized components vibrate according to their vibration mode shape, thereby improving the effect of high-frequency vibration aging in eliminating the residual stress of small-sized components, and facilitating the promotion and application of high-frequency vibration aging technology in the field of mechanical engineering.
