Embodiment 1

[0019] Such as figure 1 As shown, a high-precision rotary table driven by a torque motor includes a turntable 1, a clamping mechanism 2, a box seat 4, and a central shaft 19. The clamping mechanism 2 is installed on the inner surface of the outer ring of the turntable 1 and the box Between the outer surfaces of the seat 4, between the brake mechanism 2 and the box seat 4, an oil pressure sealing ring 3 is provided for sealing the brake oil. The seat 4 is connected to the stator 6 of the torque motor by connecting the stator flange 17, and the turntable 1 and the rotor 5 of the torque motor are connected to form an assembly through an axial radial bearing 18, and the outer ring of the axial radial bearing 18 is fixed by a hexagon socket head cap screw. On the box base 4, the torque motor stator 6 is connected to the box base 4 through the stator flange 17 to form a whole. The first adjusting washer 12 is installed in between, and the flat coupling 10 is connected with the lowe...

Abstract

The invention relates to a high-precision rotary working-table driven by a moment motor, which comprises a rotary table (1), a clamping mechanism (2), a box seat (4) and a central shaft (19), wherein, the rotary table (1) is fixed at the end part of a moment motor rotator (5); the box seat (4) is connected with a moment motor stator (6); the rotary table (1) is connected with the moment motor rotator (5) through an axial radial bearing (18) to form a component; the outer ring of the axial radial bearing (18) is connected with the box seat (4); the moment motor stator (6) is integrally connected with the box seat (4); and the hydraulic clamping mechanism (2) is mounted between the inner surface of the outer ring of the rotary table (1) and the outer surface of the box seat (4). The hydraulic braking device set in the invention has a simple structure, large clamping action area, high clamping moment, bigger braking force, stable clamping and smaller influences on system and transmission, so the invention can meet the requirements on stable rotation and reliable braking in high-grade numerical control machine and meet the processing demands with high requirements of all aspects.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and measurement, in particular to a high-precision rotary table. Background technique [0002] The existing rotary table in our country generally adopts the traditional mechanical transmission scheme, and the power source realizes the drive of the turntable through the transmission mechanism. Among them, the power source adopts a servo motor, and the intermediate transmission link adopts a gear type transmission, a rack and pinion type transmission or a worm gear type transmission. In this traditional solution, there are fewer electrical connections and lower product cost, but the machining accuracy of gears, racks or worm gears is often required to be high; this method has slow dynamic response, high noise, high energy consumption, and the existence of Factors such as elastic deformation and backlash on the mechanical transmission chain are difficult to meet the processing requirem...
