Problems solved by technology

Air intake throttling speed regulation is to control the flow into the cylinder to adjust the movement speed of the piston. With this control method, if the load on the piston rod changes slightly, it will cause a significant change in the cylinder speed, so the speed stability is poor; Throttle speed regulation is to control the displacement of the cylinder. This control method can provide back pressure for the cylinder to limit the speed. The speed stability is better than the intake throttle speed regulation method, but it needs to exhaust all the time, so the Can be big

Embodiment Construction

[0007] Such as figure 1 As shown, the speed regulating device of this cylinder includes an air source 2, a first throttle valve 4, a first pressure regulating valve 6, a diverter valve 3, a second throttle valve 5, and a second pressure regulating valve 7, The compressed gas in the gas source 2 flows into the first throttle valve 4, the first pressure regulating valve 6, and the rodless chamber 11 of the cylinder 1 through the diverter valve 3 in sequence, and the compressed gas in the gas source flows into the second throttle valve through the diverter valve 3 in sequence. The throttle valve 5, the second pressure regulating valve 7, and the rod cavity 12 of the cylinder 1.

[0008] Preferably, the cylinder 1 is a single-rod double-acting cylinder. However, it should be understood that the cylinder of the present invention may be any pneumatic device that uses compressed gas as a power source.

[0009] use as figure 1 In the shown device, the compressed gas is sent to the ...

Abstract

The invention discloses a speed regulation device of a cylinder, which is energy-saving and is capable of improving speed stability and reducing transmission gaps among a piston ring, a piston and a piston rod. The speed regulation device comprises an air source, a first throttle valve, a first pressure regulation valve, a flow divider valve, a second throttle valve and a second pressure regulation valve, compressed air in the air source flows into the first throttle valve, the first pressure regulation valve and a rodless cavity of the cylinder in sequence by the aid of the flow divider valve, and other compressed air in the air source flows into the second throttle valve, the second throttle valve and a cavity with a rod of the cylinder in sequence by the aid of the flow divider valve.

Description

technical field [0001] The invention relates to the technical field of pneumatic equipment, in particular to a speed regulating device for an air cylinder. Background technique [0002] Pneumatic equipment transmission has fast response and quick action, but the stability of action is poor. The speed control of the cylinder mainly includes intake throttling speed regulation and exhaust throttling speed regulation. Air intake throttling speed regulation is to control the flow into the cylinder to adjust the movement speed of the piston. With this control method, if the load on the piston rod changes slightly, it will cause a significant change in the cylinder speed, so the speed stability is poor; Throttle speed regulation is to control the displacement of the cylinder. This control method can provide back pressure for the cylinder to limit the speed. The speed stability is better than the intake throttle speed regulation method, but it needs to exhaust all the time, so the ...
