Robot waist rotation base

The invention provides a robot waist rotation base. The robot waist rotation base comprises a supporting body and an installation foundation platform. A round platform base is arranged on the top of the installation foundation platform, and a cylindrical rotating column extending downwards is arranged in the center of the bottom of the platform base. The supporting body comprises a supporting sleeve arranged outside the rotating column in a sleeving mode, an annular groove surrounding the rotating column by one circle is formed in the surface of the side wall of the rotating column, an oil receiving channel is formed in the rotating column, an opening is formed in the top of the oil receiving channel and extends to the upper surface of the platform base, the bottom of the oil receiving channel is communicated with the annular groove, and the supporting sleeve is horizontally provided with an oil inlet and outlet channel which directly faces the annular groove and is communicated with the annular groove. The robot waist rotation base has the advantages that continuous rotation, platform installation and oil way non-interference are integrally achieved, the structure is simple and compact, installation is convenient, maintenance is simple, the service life is long, the work efficiency of work machinery is greatly improved, and the use range of rotating machinery is expanded. The robot waist rotation base can be widely used for robots of petroleum machinery and in other industries.
