Embodiment 1

[0021] As shown in Figure 5, in the figure, 1 indicates a double-row short cylindrical roller bearing; 2 indicates an outer rotor rotary joint; 3 indicates the outer shell of the C-axis torque motor; 4 indicates the C-axis hydraulic clamping sleeve; 5 indicates C The rotor of the axial torque motor; 6 represents the stator of the C-axis torque motor; 7 represents the inner cooling sleeve (or cooling sleeve) of the stator of the C-axis torque motor; 8 represents the axial / radial bearing; 9 represents the axial / radial bearing; 10 represents the rotor of the A-axis torque motor; 11 represents the stator of the A-axis torque motor; 12 represents the hydraulic clamping sleeve of the A-axis; 13 represents the inner cooling sleeve (or cooling jacket) of the stator of the A-axis torque motor; 14 represents the encoder for the A-axis. The internal structure of the single-axis turntable 102 in the middle is the same as the single-axis turntable directly driven by the above-mentioned torq...

Embodiment 2

[0024] Since the shell of the horizontal turntable is type structure, the other end can also be symmetrically clamped on a turntable with the main axis transverse and the table vertical. And a horizontal torque motor is set for the turntable, and its correlation mode is exactly the same as that of the above-mentioned turntable 101 and its torque motor, but it needs to be set in a form corresponding to each other.

Abstract

The biax turntable of an AC permanent magnet syntactic outside rotor torque motor comprises a turntable in the middle with vertical main shaft, turntable at one side of the said turntable with horizontal main shaft connecting with horizontal torque motor and vertical torque motor, oscillating driven by the horizontal torque motor, rotating driven the vertical motor. Saving a lot of middle drive linkage, it improves the running precision and stability of the turntable, with bigger output torque, and improved mechanical returns. It simplifies the braking structure with enlarged clamping area, less effect to the drive and system, smaller size of the outside rotor torque motor.

Description

technical field [0001] The invention relates to a turntable mechanism, more specifically, to a combined mechanism for realizing arbitrary angle indexing and clamping of a biaxial turntable so as to realize workpiece cutting. Background technique [0002] Such as figure 1 In the traditional mechanical transmission scheme of the double-axis turntable shown, the power source realizes the drive of the turntable through the transmission mechanism. Among them, the power source adopts a servo motor (servo hydraulic motor), and it is used 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. Although in this traditional solution, there are fewer electrical connections and the cost of the entire product is lower, the problem is that the machining accuracy of the gear, rack or worm gear is usually higher; and due to the existence of intermediate...
