Claims

[Scope of utility model registration request]

In a multi-head grinding machine, a rotating indexing table is equipped with multiple grinding heads, and a rotating drive unit on a movable base that transmits power to one grinding head indexed to the grinding position slides in the plane direction. A support shaft is erected in the center of the movable base, and a rotary indexing base is rotatably supported on the movable base with the support shaft as the center of rotation, and the rotary indexing base has the multi-stage diameter. In addition to configuring a rotation restraint member equipped with a clamp cylinder between the supporting shaft and the movable base, a positioning member consisting of a plurality of pin holes and a locating pin is provided between the movable base and the support shaft in the movable base. A clutch member is provided between the rotating indexing base and the rotating indexing base and is moved into and out of contact with a cylinder, and the clutch member engages with a rack cylinder on the movable base and is connected to a rotating drive member that rotates the rotating indexing base by means of the rack cylinder when the clutch is engaged. An indexing device for a multi-head grinding head.
