Intelligent feedback type variable throttling buffering system and method

Abstract

The invention provides an intelligent feedback type variable throttling buffering system and a control method thereof and belongs to a variable throttling buffering system and method. According to the buffering system, one end of a direct driving cylinder is connected with a linear motor and the other end of the direct driving cylinder is connected with a stroke control valve block; the stroke control valve block is connected with a buffering cylinder through a pipeline; one end of the buffering cylinder is connected with a throttling control valve block and the other end of the buffering cylinder is connected with a cylinder cover of the buffering cylinder; the cylinder cover of the buffering cylinder is connected with a speed sensor and a displacement sensor; the throttling control valve block is connected with a controller and a pressure sensor; and the throttling control valve block is connected with a stepping motor which is coaxial with the buffering cylinder. The intelligent feedback type variable throttling buffering system has the advantages that the buffering capacity is changed along the change of impact load, so that efficient buffering is realized; a closed loop control system is adopted so that automatic adjustment of a buffering stroke and a throttling area is realized; the buffering of the impact load in a relatively large range is realized; the buffering of the uncertain impact load is realized through an automatic detection control system; the volume of a power source is effectively reduced; and the hydraulic oil leakage problem of a hydraulic buffer can be compensated.

Description

technical field [0001] The invention relates to a variable throttle flow buffering system and a buffering method thereof, in particular to an intelligent feedback type variable throttle flow buffering system and a buffering method thereof. Background technique [0002] Buffer equipment is one of the indispensable parts of various machines, but the existing buffer can only manually adjust the buffer capacity within a small range, the degree of automation is low, and the capacity and stroke of the buffer cannot be adjusted in real time according to the impact load. The buffering of overload loads cannot be completed, and the machine cannot be reliably protected; the buffering capacity can only be used below the rated buffering capacity, which cannot satisfy large-span impact buffering and uncertainty buffering. [0003] A Chinese patent discloses a hydraulic buffer that automatically adjusts the buffer force. The publication number is CN202251621. The main structure includes a...
