Description

Technical Field

[0001] This utility model relates to the field of turntable technology, specifically a servo tracking turntable. Background Technology

[0002] A turntable is a mechanical device with rotation and positioning functions. It is mainly divided into two categories: stage equipment and industrial tools. Traditional turntables are mostly used in theaters to improve scene changing efficiency by rotating the stage. In the industrial field, as a machine tool workbench, it can rotate at a fixed angle for precision machining; it is also called a rotary worktable. In the measurement and control field, single-axis or multi-axis turntables are used in scenarios such as satellite attitude control and component calibration, with positioning accuracy reaching ±0.1mm and loads ranging from 1.5 kg to 1.5 tons. Both types of turntables adopt a axial rotation structure, combining resistance to environmental interference and high-speed characteristics, adapting to different professional needs.

[0003] Existing turntables typically use a motor to drive the shaft for rotation. However, the exposed motor structure is susceptible to environmental corrosion, which affects its service life. Therefore, a servo tracking turntable is proposed. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] This utility model provides a servo tracking turntable with a longitudinal axis system and a lateral pitch axis system set inside the base. The moving structure is located inside the base, making it less susceptible to corrosion from the external environment. It achieves two-dimensional synchronous rotation in the horizontal and pitch directions and drives the equipment to perform circumferential scanning, sector scanning, positioning, and tracking actions, improving integration and reducing the equipment's footprint.

Figures 1-2It includes: azimuth axis 1, azimuth encoder 2, deep groove ball bearing 3, slip ring 4, pitch motor 5, left angular contact ball bearing 6, angular contact ball bearing pair 7, azimuth motor 8, optical component mounting base 9, omnidirectional electronic detection mounting base 10, base 11, pitch locker 12, gyroscope 13, right angular contact ball bearing 14, pitch axis 15, directional countermeasure mounting base 16, pitch encoder 17, azimuth locker 18, and base 19;

[0023] A base 19 is provided at the bottom of the base 11. An azimuth axis 1 is longitudinally arranged at the center of the base 11. A pitch axis 15 is transversely arranged inside the base 11. An omnidirectional electronic detection mounting base 10 is provided at the top of the base 11. An azimuth encoder 2, a deep groove ball bearing 3, and a slip ring 4 are provided at the upper end of the azimuth axis 1. An angular contact ball bearing pair 7 and an azimuth motor 8 are provided at the lower end of the azimuth axis 1. A pitch motor 5, a left angular contact ball bearing 6, and an optical component mounting base 9 are provided at the left end of the pitch axis 15. A pitch locker 12, a gyroscope 13, a right angular contact ball bearing 14, a pitch axis 15, a directional countermeasure mounting base 16, and a pitch encoder 17 are provided at the right end of the pitch axis 15. An azimuth locker 18 is provided on the base 19. The motor is a torque motor.

[0024] The connection gap of the base 11 is divided into a static seal and a dynamic seal. The static seal is equipped with a sealing strip, which is a double-layer hollow conductive rubber ring. The dynamic seal is equipped with a sealing ring, which is a double seal combining a labyrinth seal and a V-type servo tracking turntable seal, to ensure the sealing effect and prevent damage from environmental corrosion when working in outdoor environments.

[0025] The base 19 has connection holes at all four corners. The connection holes are threaded holes, which are used to screw the turntable onto the external worktable.

[0026] The pitch axis 15 pitch axis system has a rotation range of 0°-70°.

[0027] The base 11 is made of aluminum alloy and has a hollow structure, which reduces its weight but does not guarantee structural strength.

[0028] Specifically, the various parts of the turntable are connected by a shaft system to enable communication between the components and transmit motion. The shaft system consists of shafts, bearings, and connecting mechanisms, and the motor rotor and other connecting mechanisms are also connected to the shafts.

[0029] The azimuth axis system mainly consists of two parts: an upper part and a lower part. The upper part mainly consists of an encoder, a deep groove ball bearing, and a slip ring; the lower part mainly consists of a pair of angular contact ball bearings and a torque motor. The entire azimuth axis system uses the azimuth axis as a series carrier and the base as a frame.

[0030] The pitch axis system consists of two shafts, a motor shaft and an encoder shaft. The left shaft assembly mainly consists of a motor and one angular contact ball bearing, while the right shaft assembly mainly consists of an encoder and one angular contact ball bearing. The two shafts are connected by a pitch base, and load mounting plates are fixed at both ends of the pitch shaft.

[0031] In practical use, the base 11 is screwed to the working area via the base 19. A visible light camera is connected to the optical component mounting seat 9, an electromagnetic countermeasure is connected to the directional countermeasure mounting seat 16, a radar is connected to the front end of the base 11, and an omnidirectional electronic reconnaissance is connected to the omnidirectional electronic reconnaissance mounting seat 10. Power is provided by the azimuth motor 8 and the pitch motor 5 to drive the shaft system to rotate, thereby driving the visible light camera, electromagnetic countermeasure, and omnidirectional electronic reconnaissance to work. The movable output ends of the turntable extend out of the base 11, while the motors are located inside the base 11, allowing it to work outdoors for a long time and reducing the environmental corrosion of the turntable.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
