Abstract

The invention provides a high-precision constant force suspension device comprising a balancing weight, a motor, a suspension rope, an output cylinder, a linear guide way, a laser displacement sensor, a reflector and a bracket, wherein the side face of the output cylinder is connected to the linear guide way in a vertical direction through a sliding block; the motor is connected at the top end of a drum of the output cylinder through the suspension rope; the motor is arranged on the bracket; a fixed pulley is arranged on the bracket; the suspension rope is wound on a motor output shaft, and is connected to the balancing weight through the fixed pulley; the laser displacement sensor is arranged on the output cylinder. According to the suspension device, an air storage sleeve is additionally arranged outside the output cylinder, and constant force output precision and stability can be enhanced; the drum is driven by the suspension rope so as to realize constant force output in long distance; the other end of the suspension rope rounds the fixed pulley to be connected to the balancing weight, so that the weight is reduced, and high-mass suspension is achieved.

Description

technical field [0001] The invention relates to a constant force output device. Background technique [0002] In order to achieve constant force hanging, the common method is to connect the target workpiece with the weight reduction weight through the suspension rope and the pulley block. The weight loss weight is constant, so the hanging force acting on the target workpiece is constant, but when the target workpiece When accelerating or decelerating, the weight will generate an additional force on the target workpiece due to the influence of its own inertial force, and the greater the mass of the weight, the greater the impact, so this method is only suitable for low-speed or low-speed target workpieces. In the case of uniform motion. The constant force suspension can also be realized through the motor, sensor and rope winding assembly. The force sensor measures the tension on the suspension rope, and feeds back to the motor to control the winding rope assembly to realize ...
