Abstract

A precise control method for a buffer oil cylinder, the signal output terminals of the high-grade micro switch and the low-grade micro switch are connected to the signal input terminal signal of the servo drive, and the signal output terminal of the servo drive is connected to the control terminal signal of the servo motor connected, the signal output end of the motor encoder of the servo motor is connected to the signal of the servo driver, the signal of the servo driver is connected to the controller, and the signal of the controller is connected to the signal output end of the speed sensor provided on the load; including the second Step 1: Acquisition of load speed and sending of control commands, Step 2: PID control of servo motor rotation, Step 3: Switch feedback control, Step 4: Complete gear switching. This design is not only fast in shifting speed, but also good in reliability and high in shifting precision.

Description

technical field [0001] The invention relates to a precise control method of a buffer oil cylinder, which is particularly suitable for precisely controlling the damping of the buffer oil cylinder. Background technique [0002] Hydraulic cylinders with buffer devices are often used in the fields of machine tools, woodworking machinery, rubber machinery, steel equipment, injection molding machines, die-casting machines, marine engineering or ships, mainly to prevent the cylinder piston from moving quickly to the end of the stroke. Possible impact damage to the front and rear end caps of the cylinder block. A large winch prevents the free fall of the load from causing the winch to fly and cause damage to the winch motor; thus, an adjustable buffer cylinder is designed to protect the winch motor by buffering the free fall of loads with different weights. [0003] If the gear is adjusted mechanically, on the one hand, the efficiency of gear adjustment is low, and on the other han...
