Abstract

The invention relates to a hydraulic buffer which comprises a casing, a rear cover, an oil seal, an inner pressure cylinder block, a piston, a piston rod, an impact head, a bearing, a spring, an accumulator, a flow adjusting bolt and a flow adjusting knob. An oil storage cavity is reserved at the end of the piston rod located inside the inner pressure cylinder block. Two check valves are arranged at the rear cover and the end of the piston rod respectively. The piston rod with the check valve is charged into the casing and is closed through the oil seal. The accumulator is then charged in, and the inner pressure cylinder block is charged into the casing. The spring is charged into the inner pressure cylinder block, and the casing is closed through the rear cover. The flow adjusting bolt and the flow adjusting knob are mounted on the rear cover. The inner pressure cylinder block is provided with an oil hole.

Description

technical field [0001] The invention belongs to the field of shock absorbers, in particular to an oil pressure buffer. Background technique [0002] The oil pressure buffer is a hydraulic device that converts the impact kinetic energy into the heat energy of the hydraulic oil, and realizes the linear deceleration of the object and finally a smooth stop. [0003] In the field of decompression, the spring, rubber, and cylinder cushioning continue at the lowest linear level at the beginning of the moving object's stroke, and the reaction force gradually increases as the stroke increases. Absorbed instead of temporarily stored, the moving object eventually inevitably rebounds greatly, causing mechanical damage. At present, dampers are used as shock absorbing devices, but the defects of the damper in the oil hole system will cause the moving object to stop instantly with the peak reaction force at the beginning of the shock absorbing stroke, causing a huge mechanical shock, and ...
