Abstract

Provided is a constant power output device not affected by air tube disturbance. The constant power output device not affected by the air tube disturbance comprises a piston, a piston rod, a cylinder barrel, an end cover, a cylinder barrel cover and an air suction sleeve, wherein the air suction sleeve comprises a first air suction sleeve and a second air suction sleeve; the piston rod is connected with the piston; the piston is sleeved with the cylinder barrel; the end cover and the cylinder barrel cover are installed at the two ends of the cylinder barrel in a sleeved mode respectively; the piston rod penetrates through the cylinder barrel cover; a tiny interval is formed between the piston rod and the inner wall of the cylinder barrel cover; the cylinder barrel is sleeved with the first air suction sleeve; the cylinder barrel cover is sleeved with the second air suction sleeve; first radial orifices are evenly distributed in the circumference of the cylinder barrel; second radial orifices are evenly distributed in the circumference of the cylinder barrel cover; a first pressure relief groove is formed in the piston; a second pressure relief groove is formed in the cylinder barrel cover; an air suction hole in the end cover is connected with an air pressure transducer and a large air storage tank through air tubes. The constant power output device is not affected by the air tube disturbance, accurate in output force value, high in control precision and good in stability.

Description

technical field [0001] The invention relates to a constant force output device. Background technique [0002] According to different application environments and application requirements, there are various structures and implementation methods for constant force output. Dynamic constant force output refers to loading a constant force value on a dynamically moving target workpiece. [0003] Hanging the target workpiece through weights is the simplest and most commonly used method of applying constant force. Since the mass of the weight is constant, the force acting on the target workpiece remains unchanged, but when the target workpiece is accelerating or decelerating, the weight The weight will generate an additional force acting on the target workpiece due to the influence of its own inertial force, and the greater the mass of the weight, the greater the effect, so this method is only suitable for low-speed or uniform-speed movement of the target workpiece. Torque motors,...
