An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions. Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines. Common jobs for a dividing head include machining the flutes of a milling cutter, cutting the teeth of a gear, milling curved slots, or drilling a bolt hole circle around the circumference of a part.

The application relates to a five-axis gantry machine tool, and relates to the technical field of machine tools. The machine tool comprises a machine body, a workbench, two mounting seats, a rotary table, an indexing head and a protective device. The protective device comprises two protective covers which are provided with mounting holes for the rotation shafts to pass through; two protective sheets which are arranged on the two protective covers, abut against the rotary table and are used for blocking the contact between the chips and the rotation shafts; and two supporting mechanisms which are arranged on the rotary table, are connected with the two protective covers through rotating assemblies at one end and form a gap hole for the indexing head to pass through at the other end. The two supporting mechanisms and the two protective covers can realize the cladding protection of the rotary table. When the workpiece falls, the workpiece collides with the supporting mechanism, the supporting mechanism can buffer the workpiece, the damage to the rotary table is reduced, the chips fall on the surface of the supporting mechanism, the machining precision of the machine tool is improved, and the convenience during the chip cleaning is improved.
