Embodiment Construction

[0018] Such as image 3 ,refer to Figure 4 , illustrating the vertical and horizontal dual-purpose single-axis turntable driven by the AC permanent magnet synchronous outer rotor torque motor of the present invention. In the figure, when the turntable of the present invention is placed with surface A as the base surface, the rotary spindle of the single-axis turntable is vertical; when placed with the surface B as the base surface, the rotary spindle of the single-axis turntable is horizontal; therefore, A surface and B The surface should be a flat surface, that is to say, when the turntable is set on the two sides of A and B as the base surface, the vertical or horizontal precision of the main shaft can be accurately guaranteed.

[0019] In the figure, an axial / radial bearing 7 for realizing the rotation of the turntable is arranged between the turntable surface 8 and the rotor 5 of the torque motor. The rotary table 8 and the inner ring of the axial / radial bearing 7 are r...

Abstract

The invention relates to the vertical and horizontal single shaft rotary bench driven by an alternate permanent syntactic outside rotor torque motor. It directly fixes the bench on the end of the said torque motor rotor, connecting the shell with the inner cold bushing of the stator and the stator of the torque motor, with reduced middle drive linkages, improves the running precision and stability of the rotary bench, with bigger output torque and improved mechanical effect. It simplifies the braking mechanism with bigger clamping area, less drive effect with less size of the outside rotor torque motor under same performance conditions.

Description

technical field [0001] The invention relates to a turntable mechanism, more specifically, to a mechanical device for realizing the drive of the turntable by a torque motor. Background technique [0002] Such as figure 1 In the traditional mechanical transmission scheme of the single-axis turntable shown, the power source realizes the drive of the turntable through the transmission mechanism. Among them, the power source adopts the servo motor, and it is regarded as an independent unit, without considering the cooling inside the turntable. The intermediate transmission link adopts gear transmission, rack and pinion transmission or worm gear transmission. In addition, the characteristics of the structure and transmission form of the single-axis turntable in the prior art are: ratchet plate positioning, the servo hydraulic motor drives the gear transmission hydraulic cylinder to clamp the single-axis turntable; plane or wedge surface positioning, the servo motor drives the hy...
