Long-distance constant force output air flotation device

Abstract

The invention discloses a long-distance constant force output air floating device which comprises an output air cylinder and a following system. The output air cylinder comprises a cylinder barrel, a connecting rod piston, end covers and air floating mats. The following system comprises a linear guide rail, sliding blocks, a fixing plate, a connecting support, a motor, a laser displacement sensor and a light reflection plate. The connecting rod piston is sleeved with the cylinder barrel, the two ends of the cylinder barrel are sealed through the end covers, an axial groove is formed in the middle of the cylinder barrel, the connecting support penetrates through the axial groove to be connected with the connecting rod piston and the fixing plate, the fixing plate is installed on the linear guide rail through the sliding blocks, the motor can drive the sliding blocks to move, the number of the air floating mats is two, the air floating mats are connected with the fixing plate through air floating mat bases, and the laser displacement sensor is installed on the fixing plate. According to the long-distance constant force output air floating device, the constant force is output through the output air cylinder, the output air cylinder is controlled by the following system to achieve long-distance movement, and the long-distance constant force output air floating device is free of air pipe disturbance influences, good in stability and high in constant force output accuracy.

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,...
