Description

Technical Field

[0001] This utility model relates to the field of hollow rotating platform technology, specifically a high-torque hollow rotating platform. Background Technology

[0002] Hollow rotary platforms are mainly used in various rotary motion applications, featuring high efficiency, high precision, high rigidity, and high cost-effectiveness. As a transmission platform, its turntable has a hollow structure and uses crossed roller bearings as the support and rotation center, ensuring the turntable's coaxiality and high rigidity. The hollow rotary platform increases output torque through a single-stage helical gear reduction method, achieving high repeatability and positioning accuracy. It can be used with servo motors or stepper motors to meet various angle segmentation requirements, with positioning accuracy comparable to direct-drive motors. Traditionally, hollow rotary platforms are mostly used in a fixed position, making adjustment inconvenient. To improve this, a high-torque hollow rotary platform has been proposed.

[0003] For example, a high-torque hollow rotary platform disclosed in the authorization announcement number CN114526309B includes a hollow rotary platform body and a box. The top of the box is open, the hollow rotary platform body is located above the box, and a vibration damping device is provided inside the box.

[0004] Although it achieves initial vibration reduction by having the piston slide inside the air tube, causing the piston to compress or expand the air inside the air tube, thereby generating air resistance and allowing the gas to slowly enter or exit from the two exhaust holes, it further reduces vibration by utilizing the elastic force of the two No. 1 springs in conjunction with the elastic force of the two No. 2 springs. At the same time, the air resistance generated by the piston sliding continuously weakens the rebound force of the two No. 1 springs and the two No. 2 springs, enhancing the stability of the vibration reduction device and achieving the effect of preventing the hollow rotating platform body from being damaged by vibration during long-term operation.

[0005] However, this does not solve the problem that the existing hollow rotary platform is not convenient for flipping and adjusting the height during use, and it is not conducive to large-scale rotation and adjustment of the hollow rotary platform, thus affecting the flexibility of use. Utility Model Content

[0006] The purpose of this invention is to provide a high-torque hollow rotary platform to solve the problems mentioned in the background art, such as the inconvenience of convenient flipping and height adjustment of the hollow rotary platform, which hinders the large-scale rotation and adjustment of the hollow rotary platform and affects the flexibility of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-torque hollow rotary platform, comprising a tilting table and a tilting plate.

A lifting motor is installed at the top of each moving frame, and a lead screw is movably installed inside each moving frame, with the output end of the lifting motor connected to the lead screw. A threaded sleeve is fitted on the surface of each lead screw, and the threaded sleeve is threadedly connected to the lead screw. An integrated plate is provided inside the integrated box on one side of the moving frame, and the integrated plate is connected to the threaded sleeve.

[0008] Preferably, an electric push rod is provided on the side wall of the integrated plate, a bearing shaft is installed on the side wall of the electric push rod, and the electric push rod is movably connected to the integrated plate through the bearing shaft.

[0009] Preferably, a push arm is installed at the output end of the electric push rod, and a linkage block is installed at the end of the push arm away from the electric push rod.

[0010] Preferably, a pin is installed at one end of the linkage block near the push arm, and the linkage block is movably connected to the push arm through the pin.

[0011] Preferably, a drive shaft is installed at the end of the linkage block away from the pin shaft, and the drive shaft is movably connected to the integrated plate, and the drive shaft extends to the outside of the integrated box and is slidably connected to the integrated box.

[0012] Preferably, a rotating arm is mounted on one end of the drive shaft, an integrated base is mounted on the side wall of the rotating arm, and a servo motor is mounted on the side wall of the integrated base.

[0014] Preferably, a second worm gear is fitted onto the surface of the movable shaft, and the second worm gear meshes with the second worm.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the hollow rotating platform not only realizes convenient flipping and height adjustment for use position, facilitating a wide range of rotation and adjustment of the hollow rotating platform, but also improves the flexibility of use;

[0016] (1) The high torque motor drives the first worm wheel to rotate through the first worm, and the first worm wheel drives the rotating sleeve to rotate inside the rotating seat.

[0027] An electric push rod 20 is provided on the side wall of the integrated plate 17. The electric push rod 20 plays the role of power drive. A bearing shaft 25 is installed on the side wall of the electric push rod 20, and the electric push rod 20 is movably connected to the integrated plate 17 through the bearing shaft 25.

[0028] The output end of the electric push rod 20 is equipped with a push arm 19. A linkage block 21 is installed at the end of the push arm 19 away from the electric push rod 20. A pin 18 is installed at the end of the linkage block 21 close to the push arm 19, and the linkage block 21 is movably connected to the push arm 19 through the pin 18.

[0029] A drive shaft 15 is installed at the end of the linkage block 21 away from the pin 18, and the drive shaft 15 is movably connected to the integrated plate 17, and the drive shaft 15 extends to the outside of the integrated box 1 and is slidably connected to the integrated box 1.

[0030] A rotating arm 14 is mounted on one end of the drive shaft 15. An integrated base 9 is mounted on the side wall of the rotating arm 14.

Then, the object can be placed at the corresponding height to complete the height adjustment. When the object needs to be flipped, the flipping table 2 drives the flipping plate 3 and the rotating sleeve 5 to flip, thus completing the tilt adjustment. The system is designed for tilting and adjusting. When a large-scale rotation adjustment is required, the servo motor 10 drives the second worm gear 12 to rotate via the second worm 11. The second worm gear 12 then drives the tilting table 2, tilting plate 3, and rotating sleeve 5 to rotate via the movable shaft 13. This causes the tilting table 2 to rotate from a state perpendicular to the integrated box 1 to a state parallel to the integrated box 1. The electric push rod 20 drives the push arm 19 to move. The push arm 19 then drives the linkage block 21 to rotate via the pin 18. The linkage block 21 then drives the drive shaft 15 to rotate.
