Abstract

The invention relates to an electric cylinder, in particular to a gas-assisted electric cylinder device. The provided gas-assisted electric cylinder device comprises a motor, a flange, a bearing base,a cylinder barrel, a lead screw and a piston rod. The motor drives the lead screw to rotate, and a lead screw nut converts rotary motion into reciprocating linear motion, so that the piston rod connected with the lead screw nut is driven to do telescopic motion in the cylinder barrel; a vent hole is formed to ventilate the cylinder barrel, and a ventilation loop, an air compressor, an air storagetank and the like are used to form an air-assisted system, so that the functions of pressure maintaining, buffering and force increasing are achieved. According to the gas-assisted electric cylinderdevice, a gas-assisted device is additionally arranged in the electric cylinder, and the advantages of the electric cylinder and the air cylinder are integrated, so that the positioning precision is high; the pressurizing effect can be achieved through movement under the action of the gas-assisted device and the lead screw; and when the electric cylinder is kept at a specific position for a long time, the motor does not need to continue to increase power consumption under the action of air pressure, so that energy consumption is reduced.

Description

technical field [0001] The invention relates to an electric cylinder, in particular to a gas-assisted electric cylinder device. Background technique [0002] An electric cylinder is an actuator that uses electricity as a direct power source and has similar motion characteristics to a cylinder. Motors (such as servo motors, stepping motors, and DC motors) are usually used to drive various screws (such as trapezoidal screws, ball screws, etc.) ) or the rotation of the synchronous wheel, which is converted into linear motion through the nut or belt, and pushes the load to move. Compared with the air cylinder, the positioning accuracy of the electric cylinder is high, but if the electric cylinder maintains a specific position for a long time, its energy consumption is high. The cylinder only needs to be established to consume energy in a short time, while maintaining the position itself does not require air intake boosting at all, saving energy consumption. [0003] Therefore,...
