AI Technical Summary
In the existing technology, piston-type hydraulic accumulators lack reliable clamping fixtures during vibration, shock, and acceleration tests, leading to product failure and low testing efficiency.
A vibration clamping device for a piston-type hydraulic accumulator was designed. Utilizing the characteristics of the upper and lower clamps and the rotating cylindrical shape of the piston-type hydraulic accumulator, the clamps are fixed by welding or threaded connection, and the product is protected by a fluoroplastic gasket, achieving safe and reliable clamping and convenient disassembly.
It achieves safe and reliable fixation of piston-type hydraulic accumulators in vibration, shock, and acceleration tests, improves test efficiency, and is applicable to various test benches, facilitating disassembly and reuse.
