Problems solved by technology

However, the traditional rigid pointing mechanism has a large number of components and high cost, and the motor is generally installed on the machine to increase the inertia of the machine, making the pointing mechanism difficult to control
Or the motor is installed on the base and is driven to point to the platform through a series of transmission mechanisms. Due to the existence of transmission gaps, the friction and wear between transmission parts will greatly reduce the overall service life.

Embodiment Construction

[0017] in figure 1 , figure 2 In the schematic diagram of the present invention, there are four power input systems with the same structure on the bottom plate 18. The power input system consists of a servo motor, a servo motor frame, a coupling, a reducer, a take-up reel, a pulley and a flexible rope. . The servo motor frame 6 is arranged on the platform, and the servo motor 5 is fixed on the servo motor frame. The output end of the servo motor is connected to the input shaft of the reducer 8 through the coupling 7, and the output shaft of the reducer is connected to the take-up reel 9 through the screw and the shaft end retaining ring 10, and the take-up reel and the shaft end retaining ring are both set in On the output shaft of the reducer. Four pulley brackets 23 are provided on the platform, and each pulley bracket is provided with a pulley 17. Four rope buckles 2 are provided on the lower surface of the pointing platform 1, and the position of each rope buckle corres...

Abstract

The invention relates to a high precision flexible electric servo directional mechanism. The high precision flexible electric servo directional mechanism mainly comprises four sets of power input systems, a pointing platform, rope buckles, a height angle sensor, a shaft end retaining ring, a first hinge shaft, a connecting rod, a second hinge shaft, a lower bearing sleeve, a connecting disc, an electric cylinder, a bottom plate, a tapered roller bearing A, a tapered roller bearing B, an upper bearing sleeve, a deep groove ball bearing, an azimuth sensor and a pulley bracket. The high precisionflexible electric servo directional mechanism is advantaged in that stability is high, the quantity of parts is reduced, the rotation scope is enlarged, and the cumulative error in a series rigid pointing mechanism is eliminated.

Description

Technical field [0001] The invention belongs to the technical field of precision mechanical tracking measurement, and relates to a high-precision flexible electric servo pointing mechanism. Background technique [0002] The pointing mechanism refers to a mechanism that can change the spatial posture of the pointing platform. It has a large number of applications in antennas, reconnaissance, early warning, guidance, communications, satellite docking, etc., especially in the field of aerospace engineering, such as antenna alignment mechanism, solar photovoltaic panel to Japan mechanism and ground radar pointing mechanism, etc. , All need a large-scale, omni-directional, high-precision spatial pointing mechanism. However, the traditional rigid pointing mechanism has a large number of components and high cost, and the motor is generally installed on the machine to increase the inertia of the machine, making the pointing mechanism difficult to control. Or the motor is installed on t...
