Multi-stage buffer capable of automatically regulating buffering stage number

Abstract

The invention relates to a multi-stage buffer capable of automatically regulating buffering stage number. When buffering work is performed, the right end face of a cylinder block of a last-stage buffer serves as a contact face where the multi-stage buffer collides with a slider; electromagnetic coils are wound on the side wall of the cylinder block of the last-stage buffer; a pressure sensor used for detecting medium pressure is arranged on the right end face of a piston body assembly of the last-stage buffer, and the pressure sensor is connected with a processor module; when the slider impacts the right end face of the cylinder block, the processor module is suitable for controlling a current driving module according to a medium pressure value to output a current matched with the medium pressure value, and the electromagnetic coils are made to generate a corresponding magnetic field to attract the slider. A processor regulates or closes medium back-and-forth flow in the corresponding cylinder block according to the medium pressure detected by the pressure sensor to control moving speed and the buffering stage number of the piston body assembly of each stage buffer when the piston body assembly of each stage buffer makes piston motion.

Description

technical field [0001] The invention relates to a buffer, in particular to a multi-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 multi-stage buffer that automatically adjusts the number of buffer stages. Slider in motion. [0005] The present invention provides a multi-stage buffer that automatically adjusts the number of buffer stages, including: the multi-stage buffer is a three-stage buf...
