Abstract

The invention relates to a multifunctional five-axis mechanical arm working station. The multifunctional five-axis mechanical arm working station comprises a base, a rotating table, a back arm, a middle arm, a front arm and a terminal actuator; a second planet gear speed reducer is fixedly connected into the base; an output shaft of the second planet gear speed reducer is fixedly connected with the rotating table through a flange; the bottom of the back arm is fixedly connected with an output shaft of a second turbine worm speed reducer through a flange; the top of the back arm is fixedly connected with an output shaft of a first turbine worm speed reducer through a flange; the front arm is fixedly connected with an output shaft of a first planet gear speed reducer through a flange; a free end of the front arm is fixedly connected with a servo steering engine; and the servo steering engine is connected with a fixture. A mechanical arm has five degrees of freedom, so that the printing work is more flexible and comprehensive; and secondary machining is reduced in the side surface machining of printed objects, so that the working efficiency of 3D printing is improved. Output shafts of all motors are directly acted on the base, the back arm, the middle arm, the front arm and the terminal actuator to improve the printing precision.
