Embodiment 1

[0052] Embodiment 1: The velocity sensor 14 located at the top of the buffer cylinder detects the current velocity v of the impacting object 2 , the pressure sensor 9 located in the buffer cavity in the buffer detects that the internal pressure of the buffer cylinder is p 2 , the two are jointly input to the acquisition processor 8, and the acquisition processor 8 automatically calculates the optimal throttle area s for completing the current buffer 2 , the current buffer throttling area is s 3 , the acquisition processor 8 automatically calculates s 2 -s 3 the difference between

[0053] when s 2 >s 3 , that is, the most pre-throttling area required to complete the current buffer is greater than the current throttle area, the controller 9 controls the stepping motor 6, and the stepping motor 6 drives the spool 31 to move linearly through the lead screw 30, so that the orifice 28 is reduced by The area covered by the spool achieves the optimal pre-throttle area s for com...

Abstract

An intelligent feedback variable throttle flow buffer system and its control method belong to the variable throttle flow buffer system and its buffer method. Buffer system: One end of the direct-acting cylinder is connected to the linear motor, the other end is connected to the stroke control valve block, and the stroke control valve block is connected to the buffer cylinder through a pipeline; one end of the buffer cylinder is connected to the throttling control valve block, and the other end is connected to the buffer Cylinder head; speed sensor and displacement sensor are connected to the buffer cylinder head; controller and pressure sensor are connected to the throttle control valve block; a stepper motor coaxial with the buffer cylinder is connected to the throttle control valve block . Advantages: The buffer capacity changes with the change of the impact load to achieve efficient buffering; the closed-loop control system is used to realize the automatic adjustment of the buffer stroke and throttle area; the buffering with a large range of impact load changes is realized; the automatic detection control system realizes uncertain impact Load cushioning; effectively reducing the size of the power source; able to compensate for the hydraulic oil leakage of the hydraulic buffer.

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...
