Integrated revolving platform

Abstract

The invention relates to an integrated revolving platform which comprises a working table, motor stators, rotors, crossed roller revolving bearings, deep groove ball bearings and a machine base, wherein a spigot shaft is fixed in the center of the working table; the rotors are fixed at the middle part of the outer wall of the spigot shaft; the crossed roller revolving bearings are arranged among the working table, the rotors and the machine base; the motor stators are fixed at the middle part of the inner wall of the machine base; the outer rings of the deep groove ball bearings are fixed to the lower part of the inner wall of the machine base; the inner rings of the deep groove ball bearings are fixed to the lower part of the spigot shaft; a synchronous pulley is fixed in the position, below the inner rings of the deep groove ball bearings, on the spigot shaft; and an encoder feedback detection device is fixed in the position, corresponding to the synchronous pulley, of the lower part of the machine base. According to the integrated revolving platform, the supporting precision is high, the rigidity is high, the mechanical and electrical integration is achieved, and the mechanical transmission error is avoided.

Description

technical field [0001] The invention relates to an integrated 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 machining requirements.
