[0002] The rotary table of a floor - type milling and boring machine is a machine device used for metal processing, mainly for milling and boring large workpieces. For machining with angular requirements, in most cases, special fixtures need to be replaced to fix the workpiece, resulting in an extension of the machining time and affecting production efficiency. The head or the table of the floor - type milling and boring machine needs to be adjusted according to the machining angle, and this adjustment is complex and prone to introducing errors.

[0003] Among many existing technologies, Chinese Patent Application CN217433676U discloses a rotary table at any angle. It mainly solves the problem that when machining parts with multiple holes or surfaces with the same angular requirements on the existing floor - type milling and boring machine, multiple toolings need to be prepared, increasing the auxiliary time. One side between the sliding seat and the supporting seat is connected by a horizontal rotating shaft, and the other side is connected by a turning lead screw, and the turning lead screw is connected to a reduction gear.

[0004] However, in this patent application, the turning angle of the workbench surface is controlled by a turning lead screw, and the force application points are on two groups of rotating supports, with a large load and insufficient overall structural stability.
