Abstract

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.
