Abstract

The invention relates to a buffer capable of automatically sucking and releasing a sliding block. The buffer comprises a cylinder, wherein a cylinder cover is arranged at the opening end of the cylinder body and closes an opening, and a central through hole is formed in the central axis of the cylinder cover; a piston rod penetrates through the central through hole, and a piston body component is arranged at the top end of the piston rod; during buffering work, the right end surface of the cylinder is taken as a contact surface colliding with the sliding block; the side wall of the cylinder is wound with an electromagnetic coil, and a pressure sensor used for detecting medium pressure is arranged on the right end surface of the piston body component and connected with a processor module; when the sliding block collides with the right end surface of the cylinder, the processor module is suitable for controlling a direct current drive module to output direct current matched with a medium pressure value according to the medium pressure value, so that the electromagnetic coil can produce a corresponding magnetic field to suck the sliding block; and the processor module controls the direct current drive module to output reverse current to release the sliding block until the processor module detects that the medium pressure value is equal to an equilibrium value.

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 that automatically engages and releases the slider, which solves the technical problem that the slider rebounds when the slider hits the buffer. [0005] The present invention provides a buffer for automatically attracting and releasing sliders. The buffer includes: a cylinder body that is cylindrical and filled ...
