Claims

[Scope of utility model registration request]

In an angle head for mounting a built-in tool at a predetermined angle with respect to the main shaft of a machine tool, a connecting shaft has a bevel gear fitted to the tip and the base end is fitted and connected to the main shaft. a first fluid passage provided inside the connecting shaft; a proximal housing rotatably supporting the distal end side of the connecting shaft and fixedly supported on the machine tool via a support member; a second fluid passage provided inside the housing so as to communicate with the first fluid passage; a distal housing connected to the distal end side of the proximal housing in a state inclined at a predetermined angle; and a proximal end surface or distal end of the distal housing. an annular body connected to the surface and having a third fluid passage therein; and a hose having a proximal end connected to the second fluid passage and a distal end connected to the third fluid passage. a tool drive shaft rotatably supported in the tip housing at a predetermined angle inclined with respect to the connection shaft and fitted with a bevel gear that meshes with the bevel gear; and the tool drive shaft. A fourth fluid passage is provided inside the tool drive shaft and communicates with the third fluid passage, and a fifth fluid passage is connected to the tip of the tool drive shaft and communicates with the fourth fluid passage. a tool, and supplying cutting oil, air, or oil mist air from the machine tool side to the cutting edge side of the tool via the first, second, third, fourth, and fifth fluid passages. An angled head characterized by:
