A heavy-duty three-dimensional turntable capable of balancing the overturning moment

Abstract

A heavy load three-dimensional rotating table capable of balancing overturning moment comprises a load installing rotating table, an inverted-U-shaped supporting base, a U-shaped base, a balance connection rod, a counter weight slider, an orientation rotating barrel and a rotating table base, and mainly ZYZ Euler angle three-dimensional adjustment is achieved. The load installing rotating table and the inverted-U-shaped supporting base form an upper orientation axis Z1 axis; the inverted-U-shaped supporting base and the U-shaped base form a pitching axis Y axis; and the orientation rotating barrel and the rotating table base form a lower orientation axis Z2 axis. The Z1 axis and the Z2 axis can meet the requirement of whole circle rotation, and the pitching axis Y axis can achieve pitchingrotation in the large range. The pitching axis is provided with a counter weight device balancing the overturning moment so as to balance the overturning moment generated due to pitching, and therefore the driving torque of a pitching axis driving motor can be reduced. The device has the beneficial effects that the bearing capacity is large, a power-off anti-overturning function is achieved, andthe mechanical system reliability is high.

Description

technical field [0001] The invention relates to an attitude adjustment platform, in particular to an attitude adjustment platform for heavy product testing. Background technique [0002] In the process of testing radar or airborne electronic systems, it is generally necessary to test the working states of products in different attitudes, so devices or equipment that can adjust the attitude of such products are required. Under large-scale and heavy-load testing conditions such as large-scale radars and aircraft avionics systems, not only does the object under test need to be able to rotate in all directions, but also the weight of the device under test is generally large. Traditional hydraulic drive technology has higher cost and greatly reduced reliability, cleanliness and maintainability. The prior art is still unable to provide a better electric solution for the large and heavy-duty multi-directional attitude adjustment device. Patent 201410587952.8 proposes a large-scal...

The existing technology is still unable to propose a better electric solution for the large-scale heavy-duty multi-directional attitude adjustment device

Patent 201410587952.8 proposes a large-scale heavy-duty swing simulation table, and proposes a method of using supporting rollers to enhance the bearing capacity of the turntable in the form of auxiliary support for heavy-duty requirements, but this invention can only realize two rotations of pitch and roll degrees of freedom, and cannot achieve full rotation of the azimuth axis

Patent 201210154506.9 proposes a method of using a gravity balance system to balance the load gravity and reduce the driving torque of the motor. This invention can achieve six free movements, but the angle of its attitude adjustment cannot achieve full rotation

Patent 201310626116.1 invented a high-precision and heavy-duty turntable, which has the characteristics of large bearing capacity and high precision, but it can only realize single-degree-of-freedom movement, and cannot meet the requirements of three-dimensional attitude adjustment

Patent 201220311413.8 uses slewing support bearings to realize single-axis rotation and has a large load-carrying capacity, but because the turntable bearings are relatively small, their ability to carry overturning moments is poor, and the device cannot realize three-dimensional attitude adjustment actions
