Abstract

A twin rotation driving apparatus is provided, including a base body, an axle unit pivotally connected to the base body for carrying a workpiece, a first driving unit disposed on the base body and having a first gear set connected to the axle unit and a first motor coaxially connected to the first gear set, and a second driving unit disposed on the base body and having a second gear set connected to the axle unit and a second motor coaxially connected to the second gear set. The twin rotation driving apparatus includes two motors and two gear sets. Therefore, smaller motors can be included in the twin rotation driving apparatus, and the twin rotation driving apparatus is compact and can still generate great enough torques.

Description

technical field [0001] The invention relates to a rotatable machine, in particular to a double-rotation drive device for disposing a swivel body. Background technique [0002] Since the computing speed of the computer numerical control (CNC) controller of today's machine tools has been greatly improved, coupled with the development of computer-aided design (CAD) and computer-aided manufacturing (CAM) Software technology continues to evolve, thus allowing multi-axis machining 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 set 81 on a machine platform 80 , and a worktable 82 is provided on the first slide rail set 81 , and the workbench 82 is provided for setting workpieces to be processed (not shown). The machine platform 80 is erected with a frame body 83, and a second slide rail group 84 is set on the frame body 83, and a third sl...
