Abstract

The invention discloses a dual-rotation driving device, which comprises: a base body; a shaft unit pivotally connected to the base body to carry workpieces; a first and a second drive unit arranged on the base body; the first and second drive units Each has a motor and a gear set, each of the motors is coaxially connected with each of the gear sets, and each of the gear sets is connected with the shaft unit. Through the design of two motors and two gear sets, the present invention can generate larger torque with smaller motors and smaller volume.

Description

technical field [0001] The present invention relates to a rotatable machine, in particular to a double rotary drive device for configuring a rotating body. Background technique [0002] Due to the significant increase in the computing speed of the computer numerical control (computer numerical control, CNC) controller of today's machine tools, coupled with computer-aided design (computer-aided design, CAD) and computer-aided manufacturing (computer-aided manufacturing, CAM) Software technology is constantly evolving, thus allowing multi-axis machining technology to flourish. [0003] figure 1 It is a three-dimensional schematic diagram of the existing multi-axis processing equipment 8 . The processing equipment 8 is provided with a first slide rail group 81 on a machine table 80, and a worktable 82 is provided on the first slide rail group 81, and the worktable 82 is used for setting the workpiece to be processed (not shown). A frame body 83 is erected on the machine tabl...
