Magnetic suspension supporting rotary table

Abstract

The invention discloses a magnetic suspension supporting rotary table, belonging to the technical field of physical experiment equipment. The magnetic suspension supporting rotary table comprises an outer cylinder, wherein a rotating shaft is longitudinally inserted into the outer cylinder, a rotary table is arranged at the top end of the rotating shaft, a first magnet and a second magnet are respectively arranged on the opposite side walls of the outer cylinder and the rotary table, and a display part is arranged on the outer wall of the outer cylinder. The magnetic force can be adjusted in atargeting manner according to the specific use condition, so that the magnetic suspension supporting rotary table can be used in different environments and has a relatively wide application range; byvirtue of the cooperative use of pressure sensing equipment and the display part, and the detected pressure can be displayed through the display part, so that the displaying of the data is relativelyvisual; by arranging a sliding sleeve, the friction is relatively small during the up-down movement of the rotating shaft, and the rotation is relatively steady in use; and the resistance value of asliding resistor can be adjusted through a driving motor, so that the resistance value and an output current value can be changed.

Description

technical field [0001] The invention relates to the technical field of physical experiment equipment, in particular to a magnetic suspension support turntable. Background technique [0002] At present, with the development of my country's aerospace industry, the research and development of various types of space vehicles is in full swing. In the process of developing the space vehicle control system, in order to simulate the weightlessness effect of the space in the full physical simulation experiment on the ground, the method of hanging wire counterweight, water flotation or air flotation is usually used at home and abroad. The hanging wire counterweight method can ensure that the hanging wire deflection angle is small and the pulling force is equal to the weight of the object, so as to compensate the influence of the gravity load of the aircraft body. [0003] For example, Chinese Patent Publication No. CN201045606 discloses a single-axis magnetic levitation free turntabl...

Problems solved by technology

[0005] The purpose of the present invention is to provide a magnetic levitation support turntable to solve the problem that the existing magnetic levitation turntable proposed in the above background technology is not convenient enough to adjust the support of the turntable when in use, and the accuracy is not enough, which may easily cause the problem of reducing the adjustment accuracy.
