The present invention discloses a double-swing angle spindle head, in which an A-axis swing shaft is connected to the spindle head through the flange on the end face to realize the swing of the A-axis, and a crank connecting rod mechanism composed of a first rotating shaft, a second rotating shaft, a B-axis rotating shaft and a swing connecting rod realizes the swing of the B-axis under the push-pull action of the B-axis mechanism. Under the action of the linear push-pull mechanism, the linear axis feed movement between a ram and a saddle is realized. Thus, the freedom of movement range of the spindle head is improved, the rigidity, torque and precision of the spindle head are enhanced, and the volume and weight of the spindle head equipment are reduced.

The present invention provides a linkage swing head structure, including: a base, a drive mechanism and a spindle. The drive mechanism includes: a power mechanism, a connecting rod mechanism and a lead screw. An end of the spindle is fixed with a cutter, and the spindle is fixed on an end of the connecting rod mechanism. An end of the connecting rod mechanism fixed with the spindle is sleeved on a support bearing, the connecting rod mechanism can rotate around the support bearing, the support bearing is fixed on the base, and the other end of the connecting rod mechanism is movably connected to the lead screw. An output end of the power mechanism is connected to an end of the lead screw. The connecting rod mechanism adjusts the rotation angle of the spindle by sliding on the lead screw. The drive mechanism of the present invention is far away from the spindle, and the interference range thereof to the spindle is small. The spindle can be automatically and continuously indexed, and can also perform linkage machining with small cutting amount, and thus, when the cutter rotates by the same angle, the volume of the device is reduced; the structure is simple and the manufacturing cost is low.

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 brake 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 brake 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 fixation sheet metal and a pipeline shield. The fixation sheet metal connects the rotor seat. One end of the pipeline shield connects the fixation sheet metal, while another end thereof connects the head-installing interface so as to shield a plurality of pipelines.

A headstock assembly for a machine tool includes a mount having a female threaded bore, a headstock mounted slidably relative to the machine base, a drive member mounted on the headstock, a spindle, and a spindle extension. The spindle has an intermediate segment disposed in a chamber of the headstock and coupled to be driven by the drive member so as to permit the spindle to rotate about a spindle axis. The spindle extension is coupled to be rotatable with the spindle, and has a male threaded segment configured to be in threaded engagement with the female threaded bore so as to permit the headstock to be linearly moved relative to the mount.
