Embodiment Construction

[0029]In order to illustrate the double pendulum milling head of the present invention, a single-axis turntable driven by an AC permanent magnet synchronous external rotor torque motor is described with reference to FIG. The description of the motor structure is helpful for understanding the driving structure of the double swing milling head of the present invention. As shown in Figure 16, the rotor 5' of the motor is directly connected to the turntable table 2', and usually the table 2' is fixed to the end of the rotor 5' with bolts. At the same time, the stator 6' located in the inner ring of the rotor 5' is connected with the housing 9' fixed to the turntable by bolts. The rotation angle of the turntable is 360°×n (n represents the number of revolutions).

[0030] Permanent magnets are arranged on the inner wall of the rotor 5', and a braking mechanism 4' is arranged outside the rotor. In addition, in order to effectively cool the stator coil windings of the motor heating...

Abstract

The double pendulum milling head driven by the AC permanent syntactic rotor torque motor having a cross hollow shaft, whose both ends fixed on the rotor of the horizontal torque motor at both ends of the A shaft. Acting as an integral, they are fixed on the rotor of the vertical torque motor of C shaft. In this way, vertical motor driving the milling head to rotate around C shaft, and A shaft horizontal motor driving the pendulum of milling head around A shaft. It complete the complex machining of the working piece through compound motion in two directions matching the high speed revolution of the shaft itself. It is compact in structure, simple of drive, good in rigidity, smaller in mechanical components quantity, higher reaction sensitivity, free from wear and reverse gap, being able to machining for a five-face body with high precision.

Description

technical field [0001] The invention relates to a milling head oscillating in two directions, and more particularly, to a method of replacing the complex mechanical structure with a built-in torque motor to realize the two-directional movements of the double-swing milling head so as to realize the machining of complex sides of the workpiece. combined organization. Background technique [0002] like figure 1 The traditional mechanical transmission scheme of the double pendulum milling head shown, the power source realizes the driving of the milling head through the transmission mechanism. Among them, the power source adopts servo motor (servo hydraulic motor), and treats it as an independent unit. The intermediate transmission link adopts gear transmission, rack and pinion transmission or worm gear transmission. Although in this traditional solution, the electrical wiring is less and the cost of the whole product is lower, but the problem is that the machining accuracy of ...
