A Two-Stage Buffer with Automatic Adjustment of Buffer Stages

Abstract

The invention relates to a two-stage buffer automatically adjusting buffering stages. During a buffering operation, the right end face of a cylinder body of a final-stage buffer part serves as a contact surface colliding with a slide block; an electromagnetic coil is arranged in a side wall of the cylinder body of the final-stage buffer part in a surrounding manner; a pressure sensor for detecting medium pressure is arranged on the right end face of a piston body component of the final-stage buffer part, and connected with a processor module; when the slide block collides with the right end face of the cylinder body, the processor module controls a current drive module to output current matched with a medium pressure value to allow the electromagnetic coil to generate a corresponding magnetic field to attract the slide block according to the medium pressure value; and the processor adjusts or closes the medium traffic flow in the corresponding cylinder body to control the movement speeds or buffering stages of the piston body components according to the medium pressure detected by the pressure sensor when the piston body components of all the buffer parts make piston motion.

Description

technical field [0001] The invention relates to a buffer, in particular to a two-stage buffer which automatically adjusts the number of buffer stages. 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 automatically adjust the number of buffer stages is a technical problem in the art. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a two-stage buffer that automatically adjusts the number of buffer stages. Slider in motion. [0005] The present invention provides a two-stage buffer that automatically adjusts the number of buffer stages, comprising: the two-stage buffer includes: a first-stage buf...
