[0030] Please see Figures 1 to 4This invention discloses a hollow rotating platform according to one embodiment of the present invention, comprising a fixed base 10, on which a mounting cavity 11 and a connecting cavity 12 are provided, the mounting cavity 11 and the connecting cavity 12 being connected. The hollow rotating platform also includes a bearing 20 installed in the mounting cavity 11, a roller follower 30 disposed on the outer ring of the bearing, a convex surface fixed support assembly 40 installed in the fixed base 10, a concave surface wall connecting assembly 50 installed in the fixed base 10, an arc surface cam 60 rotatably installed in the connecting cavity 12, and a drive assembly 70 installed in the fixed base 10. The convex surface fixed support assembly 40 is installed on the fixed base 10 on one side of the mounting cavity 11, the concave surface wall connecting assembly 50 is installed on the fixed base 10 on the other side of the mounting cavity 11, the arc surface cam 60 is engaged with the roller follower 30, and the free end of the arc surface cam 60 is connected to the drive assembly 70 for transmission.

[0031] The working principle of the hollow rotating platform of this utility model is as follows: The entire fixed seat 10 is installed on the wall or ground through the concave wall connecting component 50, so that the basic structure such as the fixed seat 10, the connecting cavity 12, and the mounting cylinder cavity 11 remains stationary, providing stable support for subsequent transmission; the device to be rotated (such as a robotic arm or turntable) is installed on the convex fixed support component 40. The convex component acts as the carrier of rotation output, directly driving the load to move. After the drive component 70 is started, it transmits power to the arc-shaped cam 60, which is rotatably installed in the connecting cavity 12, driving the arc-shaped cam 60 to move. Rotating around its own axis, the arc-shaped cam 60 meshes with the roller follower 30 mounted on the outer ring of the bearing 20. The rotation of the arc-shaped cam 60 is converted into the low-speed rotation of the roller follower 30 through tooth meshing. The roller follower 30 is fixedly connected to the outer ring of the bearing 20. When the roller follower 30 rotates, it will synchronously drive the outer ring of the bearing to rotate. The convex fixed support assembly 40 is installed on one side of the mounting cavity 11 and is directly associated with the outer ring of the bearing or the rotating component. The rotation of the outer ring of the bearing will drive the convex assembly and the rotating device it carries to rotate together, ultimately realizing the on-demand rotation of the load.

[0032] Compared to existing technologies, the hollow rotating platform of this utility model can achieve platform fixation and load installation separately through the cooperation of the concave wall connecting component 50 and the convex fixed support component 40. The fixed end can be installed on a wall or the ground, and the load end can be connected to different equipment such as robotic arms and turntables without the need for additional customized installation structures. The convex and concave components are located on both sides of the installation cavity 11, which can clearly distinguish the dynamic and static areas during installation, reduce interference between the load and the fixed structure, and reduce the difficulty of installation. The roller follower 30 and the arc-shaped cam 60 are used for transmission, which has a built-in speed reduction and torque amplification effect, which can convert the power of the drive component 70 into greater torque, and it is not easy to jam when driving a heavy load.

[0033] Please see Figure 1 , Figure 2 and Figure 4The convex surface fixed support assembly 40 includes a convex surface fixed plate 41 mounted on the fixed base 10 for limiting the bearing 20, a convex surface fixed hole 42 provided on the convex surface fixed plate 41, a convex surface connecting hole 43 provided on the fixed base 10, and a convex surface connecting bolt 44 connecting the convex surface fixed hole 42 and the convex surface connecting hole 43. The convex surface fixed plate 41 directly limits the bearing 20, which can effectively prevent the bearing from axially moving or radially shifting during rotation, ensuring that the roller follower 30 and the arc-shaped cam 60 always maintain stable meshing, reducing transmission clearance and wear, and improving overall rotational accuracy. On the one hand, the bolt connection facilitates quick disassembly and assembly, and facilitates later maintenance (such as replacing bearings and adjusting loads). On the other hand, the uniform hole position can be adapted to different specifications of rotating devices (such as robotic arms and turntables), without the need for additional customized adapter structures, reducing adaptation costs.

[0034] The convex surface fixed support assembly 40 also includes a convex surface rotating plate 45 rotatably mounted on the convex surface fixed plate 41, a convex surface rotating connection hole 46 provided on the convex surface rotating plate 45, a bearing connection hole 47 provided on the bearing 20, and a rotating connection bolt 48 connecting the convex surface rotating connection hole 46 and the bearing connection hole 47. The convex surface rotating plate 45 is directly connected to the bearing 20 through the rotating connection bolt 48. When the outer ring of the bearing rotates, it can directly drive the rotating plate to rotate synchronously, reducing the intermediate links in power transmission, reducing transmission clearance and energy loss, and making the rotation of the load (such as a robotic arm) more precise and the response more sensitive. The convex surface rotating plate 45 is set independently, and the convex surface rotating connection hole 46 on its surface can be flexibly adapted to different hole layouts according to the installation requirements of the load without modifying the structure of the bearing or fixed seat 10. At the same time, the rotational cooperation between the rotating plate and the convex surface fixed plate 41 also provides space for fine-tuning the angle during load installation, adapting to more specifications of rotating devices.

[0035] Please see Figure 2 and Figure 3 The concave wall connection assembly 50 includes a concave connecting plate 51 mounted on the fixed base 10 for limiting the bearing, a concave fixing hole 52 on the concave connecting plate 51, a concave connecting hole 53 on the fixed base 10, and a concave connecting bolt 54 between the concave fixing hole 52 and the concave connecting hole 53. The concave connecting plate 51 directly limits the bearing, effectively constraining the axial and radial displacement of the bearing, preventing it from loosening or shifting during platform operation, ensuring the stable installation position of the fixed base 10 and internal transmission components (such as the arc cam 60 and the roller follower 30), and avoiding transmission misalignment or abnormal noise caused by bearing displacement. On the one hand, the tightening force of the bolts can firmly fix the concave connecting plate 51 to the fixed base 10, ensuring the overall connection strength between the fixed base 10 and the wall / ground, and it is not easy to loosen even when bearing a heavy load. On the other hand, the bolt connection is easy to disassemble and assemble, and if it is necessary to adjust the installation position or maintain the components later, the operation is simple and efficient.

[0036] The fixed base 10 also includes a support body 13, a first docking plate 14 disposed on one side of the support body 13, and a second docking plate 15 disposed on the other side of the support body 13. A convex fixed support assembly is disposed on one side of the first docking plate 14, and a concave wall connecting assembly is disposed on one side of the second docking plate 15. The first docking plate 14 is used to connect the rotating table, and the second docking plate 15 is used to connect the wall. The first docking plate 14 is specifically connected to the rotating platform, and the second docking plate 15 is specifically connected to the wall. The two are separated by the support body 13, clearly distinguishing the connection area between the rotating load and the fixed foundation. This structure can avoid friction or interference between the rotating parts and the fixed structure when they move, while reducing vibration transmission and ensuring transmission accuracy and stability of the fixed end. The support body 13, as the central core, integrates key structures such as the mounting cavity 11 and the connecting cavity 12, and can provide a stable mounting base for the internal bearings, roller followers 30, and arc-shaped cams 60. The two docking plates are connected to the support body 13 from both sides, forming a "central support + two-end force" structure, which disperses the load pressure and fixing force and reduces overall deformation. Compared with the integrated, unpartitioned fixed seat 10, this segmented structure can distribute stress more accurately, especially when bearing heavy loads, and is less prone to local breakage or loosening.

[0037] The mounting base 10 also includes a plurality of first connecting holes 16 disposed on the first docking plate 14. Different specifications of rotating table have different hole layouts. Multiple first connecting holes 16 provide more hole options, eliminating the need for additional drilling or customized docking structures. They can be directly fixed with bolts through matching holes, reducing adaptation costs. Multiple holes can be used with multiple bolts, resulting in a more even distribution of bolts. This can distribute the weight of the rotating table and the torque during operation to various parts of the docking plate, avoiding excessive force on a single point that could lead to loosening or deformation. It is especially suitable for bearing heavy loads and reducing shaking during rotation.

[0038] The mounting base 10 also includes multiple second connecting holes 17 disposed on the second mating plate 15. The drilling positions and spacing may vary on different mounting surfaces. Multiple second connecting holes 17 can provide more hole combinations, eliminating the need for additional drilling or modification of the mating plate for specific scenarios. They can be directly fixed with bolts by matching holes, resulting in stronger adaptability. Multiple holes can be used with multiple bolts, resulting in a more even distribution of bolts. This can distribute the weight of the mounting base 10 and the load, as well as the reaction force during operation, to the second mating plate 15 and the mounting surface, avoiding excessive stress at a single point that could lead to loosening or displacement. This is especially suitable for bearing heavy loads and ensuring the stability of the overall structure.

[0039] The mounting base 10 also includes a plurality of third connecting holes 18 disposed on the bottom of the support body 13. The bottom of the support body 13 can be additionally fixed to a workbench, base or other plane through the third connecting holes 18, forming a "double support" with the wall / ground of the second docking plate 15. Especially when bearing heavy loads or subjected to vibration and impact, it can reduce the displacement of the mounting base 10 and prevent the overall structure from shaking.

[0040] The drive component 70 is a servo motor.

[0041] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
