Stroke regulating device with double-piston-rod air cylinder

Abstract

The invention discloses a stroke regulating device with a double-piston-rod air cylinder. The stroke regulating device comprises an air cylinder support seat, a base, a positioning sleeve, a positioning screw nut, a regulating rod, a regulating knob, a sliding sleeve, a pressure spring, a cylinder pin and a locking screw, wherein the base and the air cylinder support seat are fixed together, a piston rod arranged at one end of the double-piston-rod air cylinder passes through a middle hole of the base and is connected with the regulating rod, and the bottom is fixedly connected with the piston rod; the pressure spring, the positioning sleeve and the regulating knob are arranged on the periphery of the regulating rod, the bottom of the pressure spring is in contact with the air cylinder support seat, and the top of the pressure spring is in contact with the sliding sleeve; the sliding sleeve is a hollow cylindrical copper sleeve, the bottom of the sliding sleeve is in contact with the pressure spring, the top of the sliding sleeve is in contact with the regulating knob, the regulating knob is in a hollow cylindrical shape, the lower half part of an inner hole is matched with the middle part of the regulating rod, the upper half part of the inner hole is matched with the upper part of the regulating rod, the upper half part of the excircle is provided with knurlings, and the top is provided with threaded holes for installing locking screws. The stroke regulating device has the advantages that the structural design is reasonable, the functions are complete, the use is safe, convenient and simple, and the regulation precision is high.

Description

technical field [0001] The invention relates to a stroke adjusting device for a double piston rod cylinder. Background technique [0002] The double-piston rod cylinder is a pneumatic actuator used in the machinery industry. The main feature is that the piston rod of the cylinder can extend from both ends, and the compressed air can make the piston move in two directions, and its speed and stroke are equal. If it is necessary to adjust the stroke of the cylinder, the commonly used methods in the industry include adding adjusting gaskets and adjusting the position of the nut on the piston rod, etc. These methods have a limited and fixed adjustment range, and cannot meet some occasions that require high precision and require frequent adjustments. Contents of the invention [0003] The purpose of the present invention is to provide a double-piston rod cylinder stroke adjustment device and its use method, which is divided into initial adjustment and use adjustment, which solve...
