Problems solved by technology

[0004] 1. With the growth of the transmission chain of the series-type stable platform, the error accumulates, which leads to the increase of the terminal error;
[0005] 2. The series-type stable platform does not have the isotropy of the parallel-type mechanism, and the isotropic response speed is inconsistent;
[0006] 3. Parallel stable platforms are generally driven by hydraulic cylinders or electric cylinders, and the response speed is slow

Embodiment Construction

[0014] The invention is a two-axis parallel stable platform driven by a voice coil motor, which eliminates transmission components such as ball screw nut pair, reducer, hydraulic cylinder, etc., shortens the transmission chain, fundamentally improves the reliability of the system, reduces The later maintenance time and cost are reduced. Aiming at the defects of the traditional stable platform, the present invention uses a voice coil motor to directly drive the load, and aims at the fact that the voice coil motor has no self-locking function after power failure, and adds a power-off locking device at the swing shaft end of the branch chain to achieve After power failure, the moving branch chain degenerates into a rigid truss to realize self-locking after power failure, so that the whole machine is in a controllable state.

[0015] The two-axis parallel stable platform of the present invention includes a base, a moving platform, and two branch chains (including motor base, voice...

Abstract

The invention discloses a two-axis parallel type stable platform. The platform is driven by a voice coil motor and is specific to the condition that the voice coil motor cannot be locked by itself after losing power. A power losing brake sticking device is arranged at the bottom of a branch chain, and the overall machine is in a controllable state after power losing. By means of the two-axis parallel type stable platform, the function requirements of ship-based equipment or vehicle-mounted equipment or other precise equipment needing to isolate external interference can be met.

Description

technical field [0001] The invention relates to the technical field of stable platforms, in particular to a two-axis parallel stable platform. Background technique [0002] Vehicle-mounted equipment or ship-borne equipment will be affected by bad weather, road conditions or waves and non-contact adverse factors during normal work, and various interference movements generated will bring many negative effects to the corresponding equipment. Since the stable platform can effectively isolate the interference movement of the external azimuth, roll and pitch, it can keep the motion carriers such as precision instruments installed on the stable platform stable relative to the geographic coordinate system, or under the action of relevant instructions, make the The stable object moves relative to the established inertial space according to the expected motion law, so that related equipment can play a better role to meet the needs of related operations. Therefore, stable platforms ha...
