Description

Technical Field

[0001] This utility model relates to the field of rotating platform technology, specifically a fine-tuning device for a hollow rotating platform. Background Technology

[0002] Hollow rotary platforms can be used in various rotary motion applications, combining high efficiency, high precision, high rigidity, and high cost-effectiveness. They achieve automated angle adjustment through motor drive, feature a hollow structure for easy installation of air pipes and electrical wires, and can rotate without dead angles. Suitable for the automation industry, hollow rotary platforms can replace DD motors and cam dividers, and have characteristics such as high repeatability and strong load-bearing capacity. Traditional hollow rotary platforms are often inconvenient for fine adjustment. To improve this situation, a fine adjustment device for hollow rotary platforms is proposed.

[0003] As disclosed in the authorization announcement number CN207982927U, a hollow rotary platform fine-tuning device includes a housing, a connecting flange, and a transition flange. An external gear ring is installed inside the housing. The connecting flange and the transition flange are connected in sequence to the lower side of one side of the housing. An input shaft is installed inside the connecting flange and the transition flange to realize power transmission. One end of the input shaft extends upward and has a drive gear. A fine-tuning structure is also provided on the housing. The fine-tuning structure includes a flat-end set screw. The flat-end set screw is screwed onto the side end face of the housing. Rotating the flat-end set screw drives the connecting flange and the input shaft to move forward as a whole to adjust the center distance between the external gear ring and the drive gear.

[0004] Although it uses rotating screws to adjust the meshing clearance of internal gears, its structure is simple and easy to operate. At the same time, it can make the meshing of internal gears reach zero clearance, improve positioning accuracy, and reduce processing and manufacturing costs. However, it does not solve the problem that the existing rotary platform is not conducive to convenient circumferential rotation and angle adjustment during use, and it is not conducive to the position movement and adjustment of the hollow rotary platform, which affects the flexibility of use.
