Problems solved by technology

At present, most of the turntable bearings are hydrostatic bearings, the static pressure floating amount changes greatly with the external load, the rigidity of the oil film is poor, and the generation of the hydrostatic oil film is difficult, which also leads to the high precision retention of its structure. on the disadvantages
Moreover, the use of hydrostatic bearings leads to high processing requirements for machine tools, difficult assembly, complex hydraulic systems, and high failure rates, which further reduce the reliability of machine tools.

Abstract

The invention provides a direct-driven rotating table. The direct-driven rotating table comprises a rotary table, a box body seat, a torque motor and a locking component, wherein the rotary table is rotationally connected to the box body seat through a rotary table bearing; the torque motor is arranged between the rotary table and the box body seat; a stator and a rotor of the torque motor are fixedly connected to the box body seat and the rotary table respectively; and the relative position between the rotary table and the box body seat is fixed through the locking component. Through cooperation of the torque motor and the rotary table bearing, the rotary table is fixed and driven, the torque motor directly drives the high-precision rotary table, a speed reduction transmission gear is omitted, the corresponding speed of the high-precision rotary table is increased, meanwhile, transmission errors are eliminated, and the operation precision of the system is improved. The rotary table is locked through the locking component, the stability of the position of the rotary table is improved, and it is guaranteed that the angle of the rotary table does not change in the long-time working process.

Description

technical field [0001] The present disclosure relates to the field of machining, and in particular to a direct-drive rotary table and a cylindrical grinder including the same. Background technique [0002] The development of modern CNC machine tools tends to be more and more high-speed, high-precision, and intelligent. As a key accessory of precision grinding equipment, the rotary table (high-precision B-axis system) also faces the requirement of high-precision development. [0003] As the core component of the turntable, the turntable bearing not only needs to have a high carrying capacity, but also needs to have high rotation accuracy, high anti-overturning ability, and high speed capability during the operation of the turntable. At present, most of the turntable bearings are hydrostatic bearings, the static pressure floating amount changes greatly with the external load, the rigidity of the oil film is poor, and the generation of the hydrostatic oil film is difficult, whi...
