Technical Field

The invention belongs to the technical field of buffers, and particularly relates to a buffer with a linear-moving adjustable buffer assembly.

Background

The industrial oil pressure buffer is an energy absorption element applied to the automation industry, and can absorb the kinetic energy of a moving object to stably decelerate and stably stop the moving object. Can improve the production efficiency and prolong the service life of equipment. The hydraulic shock absorber is classified into an adjustable type and a non-adjustable type according to a damping effect, and the non-adjustable type means that the damping effect of the shock absorber is fixed and there is no flow rate adjusting hole of an oil passage. The adjustable buffer is internally provided with a flow adjusting hole, and the sectional area of the flow adjusting hole can be adjusted, so that the variation of the damping force is realized, and the larger the sectional area of the adjusting hole is, the easier the hydraulic oil in the buffer passes through the adjusting hole, and the smaller the damping force is buffered. On the contrary, the smaller the sectional area of the adjusting hole is, the less the hydraulic oil is easy to pass through, and the damping force of the buffer is increased.

The pipe wall of the inner pipe of the existing buffer is provided with a plurality of throttling holes communicated with the interlayer space of the outer pipe, the throttling holes are arranged at intervals, when the piston moves, the throttling holes are closed one by one, and the fluctuation of damping force is generated once when the piston passes through one throttling hole, so that the buffering effect is not stable and smooth enough.

Disclosure of Invention

The present invention is directed to solve the above problems, and an object of the present invention is to provide a buffer having a linearly movable adjustable buffer assembly, so as to achieve a smooth and stable buffering effect. In order to achieve the purpose, the technical scheme of the invention is as follows:

the buffer with the linear moving adjustable buffer assembly comprises an inner tube, a shaft core piston assembly arranged at one end in the inner tube and a buffer assembly arranged at the other end in the inner tube; a relatively sealed buffer cavity is formed between the buffer assembly and the shaft core piston assembly, the adjusting bolt in the buffer assembly moves linearly and is relatively inserted into the throttling channel of the shaft core piston assembly, and the adjusting bolt is in clearance fit with the throttling channel.

Specifically, the outer pipe is sleeved on the outer portion of the inner pipe in a fitting mode.

Specifically, one end of the inner tube is provided with an adjusting sleeve extending to the buffer cavity, the other end of the inner tube is provided with an end cover sealing the end of the inner tube, and an adjusting channel communicated with the outside is arranged in the adjusting sleeve.

Specifically, an O-shaped sealing ring and pressure accumulation cotton are clamped between the end cover and the inner wall of the inner pipe, and a baffle ring for blocking the side edge of the pressure accumulation cotton is arranged at the inner end, located in the buffer cavity, of the end cover.

Specifically, the shaft core piston assembly comprises a shaft core penetrating through the end cover and extending to the buffer cavity, a piston connected with the shaft core, and a spring clamped between the adjusting sleeve and the piston.

Specifically, a throttling channel axially penetrating through the piston is arranged in the shaft core, an overflow hole penetrating through the throttling channel is radially arranged on the shaft core, and an overflow gap is reserved between the overflow hole and the inner wall of the inner pipe.

Specifically, the inner end of the shaft core is provided with a stop block limited at the inner end of the stop ring.

Specifically, the buffering assembly comprises an adjusting screw movably arranged in the adjusting channel and an adjusting bolt connected with the adjusting screw and extending into the throttling channel through the adjusting sleeve.
