Abstract

The invention relates to a working method of a buffer with a processor module automatically adjusting stress buffer. The buffer comprises a cylinder, a cylinder cover is arranged at the open end of the cylinder and seals the opening of the cylinder. A central through hole extending axially is formed in the cylinder cover. A piston rod penetrates through the central through hole. A piston body component is arranged at the top end of the piston rod and suitable for conducting piston motion in the cylinder. An electromagnetic coil is arranged in the side wall of the cylinder in a winding mode. A pressure sensor used for detecting medium pressure is arranged on the right end face of the piston body component and connected with the processor module. When a sliding block collides with the right end face of the cylinder, the processor module controls a direct current drive module to output direct current matched with the value of the medium pressure according to the value of the medium pressure so that the electromagnetic coil can generate a corresponding magnetic field to attract the sliding block. The processor module controls the direct current drive module to output direct current reversely to release the sliding block till the value of the medium pressure measured by the processor module is an equilibrium value.
