Abstract
Provided is a machine tool hand including a body portion that is mounted so as to be attachable to and detachable from a spindle of a machine tool, and that is provided with a flow path connected to a coolant-liquid supply path formed in the spindle; and two or more hand members that are attached to the body portion such that at least one of the hand members is pivotable about a prescribed axis, and that are capable of gripping an object therebetween by being closed. The flow path is provided with discharge ports via which a coolant liquid supplied from the coolant-liquid supply path is discharged toward surfaces of the hand members that are exposed to an outside, and a pressure of the coolant liquid causes an opening operation or a closing operation of the hand members.
Claims5
A machine tool hand comprising:
- a body portion comprising a flow path, the body portion configured to be detachably mounted to a spindle of a machine tool and the flow path configured to fluidically connect with a coolant-liquid supply path formed in the spindle;
- two or more hand members that are attached to the body portion such that at least one of the two or more hand members is pivotable about a prescribed axis;
- and
- a movable body configured to push a corresponding one of the two or more hand members,
- wherein the two or more hand members, when in a closed state, are capable of gripping an object therebetween,
- wherein the flow path is provided with discharge ports via which a coolant liquid supplied from the coolant-liquid supply path is discharged from the body portion to impinge upon surfaces of the two or more hand members, the surfaces being disposed to an outside of the body portion,
- wherein the movable body is disposed at a vicinity of the discharge port in the flow path so as to be movable along the flow path,
- and
- wherein a movement of the movable body causes an opening operation of the two or more hand members or a closing operation of the two or more hand members.
