A kind of buffer suitable for preventing the sliding block from rebounding after hitting

Abstract

The invention relates to a buffer suitable for preventing a sliding block from rebounding after collision. The buffer comprises a cylinder. A cylinder cover is arranged at the opened end of the cylinder in a sealed mode and seals an opening. A center through hole is formed in a central axis of the cylinder cover. A piston rod penetrates through the center through hole and a piston body assembly is arranged at the top end of the piston rod. When buffering is performed, the right end face of the cylinder serves as a contact face which is collided with the sliding block. An electromagnet is axially arranged in a side wall of the cylinder. A pressure sensor for detecting pressure of media is arranged on the right end face of the piston body assembly and connected with a processor module. When the sliding block is collided with the right end face of the cylinder, based on a medium pressure value, the processor module controls a current drive module to output currents matched with the media pressure value so as to make the electromagnet generate a corresponding magnetic field to be combined with the sliding block in an attracted mode until the medium pressure value detected by the processor module is a balanced value; the processor module controls the current drive module to cut off outputting of the currents to release the sliding block.

Description

technical field [0001] The invention relates to a buffer, in particular to a buffer using elastic colloid as a buffer medium. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] However, when the slider hits the buffer, due to the excessive impact energy, the piston in the buffer has no time to work, causing the slider to rebound. How to avoid this scene is a technical problem in this field. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a buffer suitable for preventing the rebound of the slider after being hit. The buffer solves the technical problem of the rebound of the slider when the slider hits the buffer. [0005] The invention provides a buffer suitable for preventing the rebound of the slider after being hit, comprising: a cylindrical cylinder fo...
