Problems solved by technology

[0003] The wall of the inner tube of the existing buffer is provided with a number of orifices connected to the interlayer space of the outer tube. The orifices are arranged at intervals. When the piston moves, the orifices are closed one by one. A fluctuation of the damping force makes the buffering effect not smooth enough

Abstract

The invention discloses a buffer with a linear movement adjustable buffer assembly. The buffer comprises an inner pipe, a shaft core piston assembly arranged at one end in the inner pipe and the buffer assembly arranged at the other end in the inner pipe, wherein a relatively sealed buffer cavity is formed between the buffer assembly and the shaft core piston assembly; and an adjusting bolt in thebuffer assembly is linearly and relatively inserted into a throttling channel of the shaft core piston assembly in a moving mode and is in clearance fit with the throttling channel. The buffer achieves the stable and smooth buffer effect.

Description

technical field [0001] The invention belongs to the technical field of buffers, in particular to a buffer with a linearly movable adjustable buffer assembly. Background technique [0002] Industrial hydraulic shock absorbers are energy absorbing components used in the automation industry, which can absorb the kinetic energy of moving objects and make them decelerate smoothly and stop stably. It can improve production efficiency and prolong equipment life. According to the buffering effect, the hydraulic buffer is classified into adjustable type and non-adjustable type. The non-adjustable type means that the damping effect of the buffer is fixed and there is no flow adjustment hole for the oil circuit. There is a flow regulating hole inside the adjustable buffer, which can adjust the cross-sectional area of ​​the flow hole, so as to realize the change of the damping force. The larger the cross-sectional area of ​​the regulating hole, the easier it is for the hydraulic oil in...
