Abstract

The invention discloses a six-dimensional force measuring device based on gas lubrication mechanical decoupling, solves the problem of large measurement error of the existing six-dimensional force measuring device, and belongs to the technical field of six-dimensional force measuring devices. The device comprises a bearing platform, a weighing measurement system, an air floatation lubrication device, a horizontal force measurement system and a base. The weighing measurement system comprises N weighing sensors; the air floatation lubricating device comprises an upper panel and an air floatation bearing; the N weighing sensors are fixed on the upper surface of the upper panel, the bearing platform is arranged on the N weighing sensors, the bearing platform is used for placing a tested product, and the air bearing and the base are arranged below the upper panel; the air bearing is placed on the base, a layer of air film is formed between the air bearing and the upper surface of the base in the working state, pressure and torque borne by the air bearing are borne, and meanwhile friction force borne by the air bearing when the air bearing moves in the plane where the base is located is eliminated; and the horizontal force measuring system is installed on the side face of the upper panel and used for measuring transverse force and torque borne by the upper panel.

Description

technical field [0001] The invention relates to a six-dimensional force measuring device based on gas-lubricated mechanical decoupling, and belongs to the technical field of six-dimensional force measuring devices. Background technique [0002] The technology of six-dimensional force measuring device is very important for the research of precision manufacturing assembly, robot motion perception and so on. The six-dimensional force measuring device technology can realize the rapid and high-precision measurement of the six-dimensional force on the product. At the same time, according to the special working scene, the six-dimensional force measuring device technology needs to meet additional specified requirements. [0003] Existing six-dimensional force measurement devices usually adopt a strain-stress calculation method based on the sensor structure, that is, the strain of the structure is measured by multiple strain sensors, and the six-dimensional force on the sensor is ca...
