Abstract

The invention discloses a heavy-load numerical control rotating table which comprises a disc-shaped table, a rotating table body, a main shaft, a worm wheel frame and a worm gearing system, wherein one end of the main shaft is fixed on the rotating table body; the worm wheel frame is rotatablely connected with the main shaft through a main shaft bearing; the upper end of the worm wheel frame is fixedly connected with the table; a static locking system for locking the table is arranged along the circumference direction of the lower end surface of the table; and a plurality of damping dynamic vibration absorbing systems for eliminating the vibration of the table in cutting are arranged along the circumference direction of the lower end surface of the worm wheel frame. By arranging the static locking system and the damping dynamic vibration absorbing systems, the rigidity of the rotating table in both the static state and the dynamic state can be ensured, and simultaneously the working accuracy of an assorted host computer can be improved.

Description

technical field [0001] The patent of the present invention relates to an indispensable functional part (auxiliary machine) of a large metal cutting machine tool, that is, a heavy-duty numerical control rotary table, involving milling and boring machines, numerical control gear hobbing machines, etc. for processing large workpieces. It can be used as a workpiece with a maximum load of 60 tons for rotary motion and indexing motion at any angle. It can perform strong cutting processing under the static locking state of the table, and can have sufficient motion rigidity when the table is in continuous rotary motion. Carry out work with high precision and high quality. Background technique [0002] The "Major Project of High-end CNC Machine Tools and Basic Manufacturing Equipment" clearly pointed out that by 2020, 70% to 80% of the high-end CNC machine tools and basic manufacturing equipment required for the manufacture of aerospace, shipbuilding, automobiles, and power generati...
