It combines cam technology and roller mechanism, which can rotate while allowing the center section to remain hollow, thus providing a passage through the rotary platform. This design is very useful in many industrial applications, such as automation equipment, robots, assembly lines and other applications that require high-precision positioning;

[0003] In the prior art, the rotation speed generated by the rotation of the central control rotating platform is relatively fast, and the output stress is relatively small, which easily leads to damage of the device and the overall cost is relatively high;

[0004] In order to overcome the above shortcomings, the Chinese patent of the prior art (publication number CN213393380U) discloses a cam-type hollow rotating platform, wherein a plurality of rotors are arranged around the periphery of the hollow rotating platform, and each of the rotors is driven by a cam transmission mechanism, so that the plurality of rotors output power to the output rotating disk to produce a decelerated operation, which can greatly improve the output power, torque, strength and precision, and at the same time achieve the purpose of reducing costs, reducing the volume and not occupying space, so as to improve the overall work efficiency;

[0005] Although the existing technology can overcome the above-mentioned deficiencies, there are still other problems in its operation process. For example, when the central control rotating platform is rotated, the internal parts of the device are exposed to the air for a long time, which is prone to corrosion, oxidation and rust, affecting the transmission efficiency of the central control rotating platform, resulting in the consumption of kinetic energy, which is not conducive to the transmission of energy to drive rotation. Utility Model Content

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a cam roller hollow rotating platform, comprising a platform shell and a transmission component fixedly installed on the right side of the platform shell, and an output rod is fixedly installed at the output end of the transmission component, and the output rod penetrates and installs a limit sleeve, and the lower end of the limit sleeve is fixedly installed on the inner wall of the platform shell, the middle end of the output rod is provided with a rotating cam, and the middle end of the platform shell penetrates and rotates to provide a hollow fixed block;

[0008] An oil storage tank is fixedly mounted on the upper end of the platform shell, and an anti-wear mechanism is provided below the oil storage tank, and the anti-wear mechanism is provided with a spraying port, and the lower end of the spraying port is fixedly mounted on the lower end inner wall of the platform shell;

[0009] A belt is nested and installed on the left side of the output rod, and a uniform oil supply mechanism is arranged at the front end of the belt, and the uniform oil supply mechanism is provided with a rotating rod, and the left side of the rotating rod is nested and installed with the front end of the belt.

[0010] Furthermore, a through hole is formed inside the hollow fixing block, and a roller block is fixedly mounted on the outer side of the middle end of the hollow fixing block, and the roller block is meshed with the rotating cam at corresponding positions.

[0011] Furthermore, a feed port is fixedly installed at the upper end of the oil storage tank, a filter screen is nested inside the feed port, and a one-way flow guide pipe is installed through the right side of the feed port.

[0012] Furthermore, a one-way valve is arranged inside the one-way flow guide pipe, and the lower end of the one-way flow guide pipe is installed through the upper end of the transfer bin, and the lower end of the transfer bin is fixedly installed on the lower end inner wall of the platform shell.

[0013] Furthermore, a connecting pipe is installed through the right side of the transfer bin, and the right end of the connecting pipe is installed through the front end of the spraying port, and the output end of the spraying port is aligned with the surface of the rotating cam.

[0014] Furthermore, the rotating rod is rotatably mounted on the platform shell, and a threaded section is arranged on the right side of the rotating rod, and the threaded section is arranged as a reciprocating thread, and a piston plate is threadedly mounted on the surface of the threaded section.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The combination of the rotating cam and the roller block can drive the central control rotating platform to rotate. As the transmission component drives the output rod to rotate, the output rod can rotate inside the platform shell under the limit of the limit sleeve. When the output rod rotates, the rotating cam at the middle end rotates, and the rotating cam contacts the roller block meshed with its rear end. At this time, the hollow fixed block drives the rotation inside the platform shell, so that the rotation can be decelerated and stable. At the same time, a through hole is opened inside the hollow fixed block, which can reduce the weight of the device and facilitate the installation of the rotating equipment that needs to be driven, improve the effect of stable rotation, and the applied stress is large and stable.

[0018] Furthermore, before use, lubricating oil can be added in a portable manner. Lubricating oil is added to the oil storage tank through the feed port. A filter is nested inside the feed port. When adding lubricating oil, the lubricating oil is first filtered through the filter. The filter can be taken out and cleaned in a portable manner, which is convenient for the staff to operate, ensures the purity of the lubricating oil, and avoids impurities causing wear on the connection when the cam roller rotates.

[0019] Furthermore, a one-way guide pipe is provided through the right side of the oil storage tank, which can transport the lubricating oil in the oil storage tank into the transfer bin in one direction. The lubricating oil in the transfer bin is transported to the spraying port through the connecting pipe, and the spraying port is aimed at the rotating cam to spray the lubricating oil, so as to achieve the effect of conveniently adding lubricating oil, which can avoid wear and rust inside the device after long-term use, and avoid consumption of rotating force;

[0020] 2. When the output rod rotates, a synchronous rotation structure can be formed with the rotating rod through the belt. When the rotating rod rotates, a threaded section is set on the right side thereof. A piston plate is threadedly installed on the surface of the threaded section. The piston plate is limited by the limiting rod. As the device rotates, the lubricating oil can be sprayed evenly and indirectly, thereby improving the uniformity of lubricating oil addition, avoiding waste, and improving the effect of stable addition.
