Rotary working table

Abstract

The invention relates to a rotary working table. The rotary working table comprises a working surface, a motor stator, a rotor, a crossed roller swing bearing, a deep groove ball bearing and a table base, wherein a spigot shaft is fixed in the center of the working surface; the rotor is fixed in the middle of the outer wall of the spigot shaft; the crossed roller swing bearing is arranged among the working surface, the rotor and the table base; the motor stator is fixed in the middle of the inner wall of the table base; the outer ring of the deep groove ball bearing is fixed with the lower part of the inner wall of the table base; the inner ring of the deep groove ball bearing is fixed with the lower part of the spigot shaft; a synchronous pulley is further fixed in the position, below the inner ring of the deep groove ball bearing, of the spigot shaft; an encoder feedback detection device is fixed in the position, corresponding to the synchronous pulley, of the lower part of the table base; cylinder locking levers are arranged in the side wall of the table base, and a friction brake pad is fixed at the top of each cylinder locking lever. The rotary working table is high in support precision and high in rigidity, realizes mechanical and electrical integration and avoids mechanical transmission errors.

Description

technical field [0001] The invention relates to a rotary worktable. 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.
