Integrated high-accuracy servo revolving platform

Abstract

The invention relates to an integrated high-accuracy servo revolving platform which comprises a working table facet, a motor stator, a rotor, a crossed roller revolving bearing, a deep-groove-ball bearing and a machine base. The center of the working table facet is fixedly provided with a centering shaft, the rotor is fixed to the middle of the outer wall of the centering shaft, the crossed roller revolving bearing is arranged between the working table facet and the machine base, the motor stator is fixed to the middle of the inner wall of the machine base, an outer ring of the deep-groove-ball bearing is fixed to the lower portion of the inner wall of the machine base, an inner ring of the deep-groove-ball bearing is fixed to the lower portion of the centering shaft, and a synchronous pulley is further fixed to the position, located below the inner ring of the deep-groove-ball bearing, of the centering shaft; an encoder feedback detection device is fixed to the position, corresponding to the synchronous pulley, of the lower portion of the machine base, the side wall of the machine base is further internally provided with cylindrical locking levers, and the lower end of the centering shaft is further connected with a hydraulic revolving connector. The integrated high-accuracy servo revolving platform is high in supporting accuracy, high in rigidity, electromechanically integrated and free of mechanical transmission error.

Description

technical field [0001] The invention relates to an integrated high-precision servo rotary platform. Background technique [0002] The rotary table is the core component of various machine tools such as vertical lathes, milling machines, machining centers, and CNC gear shaping machines. The movement accuracy, bearing capacity, and ability to deal with impacts of the rotary table are related to the production and processing of the entire machine tool. Capacity and efficiency. In order to improve the accuracy, the existing rotary table usually uses the servo drive mechanism and the speed reduction device to drive the rotary table to rotate. However, due to the large size and complex structure of the rotary table in this way, the overall load-carrying capacity is affected. , which in turn affects the stability, and it is inconvenient to maintain later, and although this type of rotary table is more accurate than other rotary tables, it still cannot meet the high-precision machin...
