Abstract: A direct-drive two-axis machining head includes a head-drive unit and a shaft-drive unit. The head-drive unit includes a head-installing interface, a first motor, an axis-A supporter, and a first braking module mounted at an outermost rim of either a first motor seat or a stator of the first motor for braking the axis-A supporter. The shaft-drive unit further includes an axis-A-installing interface, a second motor, a shaft connector, and a second braking module mounted at an outermost rim of a second motor seat of the second motor for braking the shaft connector. The head-drive unit further includes a towline fixation sheet metal and a towline pipeline shield. The towline fixation sheet metal connects the rotor seat. One end of the towline pipeline shield connects the towline fixation sheet metal, while another end thereof connects the head-installing interface so as to shield a plurality of pipelines.

Abstract: A support mechanism includes a fixed body, a rotating unit, a moving unit and a driving unit. The rotating unit is rotationally mounted to the fixed body. The moving unit, disposed at the fixed body, includes a ball screw spline shaft, a ball screw nut and a ball spline nut. The ball screw nut and the ball spline nut are both rotatably disposed at the ball screw spline shaft moved together with the rotating unit. The driving unit, disposed at the fixed body, includes a first driving member and a second driving member to rotate the ball screw nut and the ball spline nut, respectively. With different rotation pairs of the ball screw nut and the ball spline nut to the ball screw spline shaft, the ball screw spline shaft is driven to move, and the ball screw spline shaft is further to move the rotating unit.
