AC five-axis linked double swing heads

Abstract

The invention belongs to the field of accessories of milling machines and particularly discloses AC five-axis linked double swing heads. The AC five-axis linked double swing heads comprise an A-axis shell, a C-axis flange plate, a C-axis connecting plate, a mounting flange and a C-axis compound motor. The C-axis compound motor is fixed to a first mounting flange, the first mounting flange is fixedto the upper end of the C-axis connecting plate, the lower end of the C-axis connecting plate is connected to the C-axis flange plate in a sleeving manner, the C-axis flange plate is fixedly connected to an output shaft of the C-axis compound motor, the C-axis flange plate is fixed to the upper end of the A-axis shell, a spindle sleeve and a spindle are arranged in the middle of the A-axis shell,and the spindle is fixed to the spindle sleeve. As the A-axis compound motor and the C-axis compound motor in the AC five-axis linked double swing heads are the A-axis compound motor and the C-axis compound motor integrating reducers with the motors, the size of the AC five-axis linked double swing heads is reduced, so that the inertia of a moving part is reduced, and the dynamic response and precision are improved.

Description

Technical field [0001] The invention discloses the field of milling machine accessories, and more specifically discloses an AC five-axis linkage double swing head. Background technique [0002] The existing five-axis linkage is based on three linear coordinate motions, plus two angular coordinate motions, which can coordinate motions simultaneously under the control of the computer numerical control system to realize the five-axis relative linkage between the milling machine and the parts to be processed. In this way, the cutting edge part of the cutter head always moves along the tangent direction of the curved surface to be processed, so that the curved surface processing can reach the ideal cutting state, and the processing of the part at any angle can be realized. However, the traditional AC five-axis linkage double swing head is locked When tightening, the enveloping locking method is adopted, and a large part of the force of the locking method is used on the bearing, which ...

Problems solved by technology

[0002] The existing five-axis linkage is based on 3 linear coordinate movements, plus 2 angular coordinate movements, which can coordinate the movement at the same time under the control of the computer numerical control system, and realize the five-axis relative linkage between the milling machine and the parts to be processed. In this way, the cutting edge of the cutter head always moves along the tangential direction of the curved surface to be processed, so that the curved surface can be processed to an ideal cutting state, and the processing of parts at any angle can be realized. However, the traditional AC five-axis linkage double swing head is locked When tightening, the embracing locking method is adopted, and most of the force of this locking method is used on the bearing, which can easily cause the axial and radial deformation of the bearing, and easily cause displacement, resulting in bearing wear and affecting Accuracy indicators of the AC axis, resulting in poor service life, poor positioning accuracy and reduced work efficiency
