Machine Tool Hand with Anti-Clogging Coolant Flow Design
Here’s PatSnap Eureka !
Summary
Problems
Existing machine tool gripping devices face challenges in efficiently gripping and handling workpieces without clogging due to fine chips mixed in the coolant liquid, and they often require complex mechanisms for opening and closing operations.
Innovation solutions
A machine tool hand with pivotable hand members driven by a coolant liquid flow path and discharge ports, utilizing a coil spring for closing force and a branched flow path design to prevent clogging, allowing the coolant liquid to flow externally and guide the hand members for opening and closing operations.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a gripping device uses a coolant liquid supplied to a spindle to drive hand members, then the device can utilize existing coolant infrastructure, but chip clogging occurs in the coolant liquid affecting reliable operation
Why choose this principle:
The flow path is divided into multiple separate channels: a first flow path for driving the hand members and a second flow path for discharging coolant liquid. This segmentation prevents chips mixed in the coolant from clogging the driving mechanism, while still utilizing the coolant liquid supply from the spindle.
Principle concept:
If a gripping device uses a coolant liquid supplied to a spindle to drive hand members, then the device can utilize existing coolant infrastructure, but chip clogging occurs in the coolant liquid affecting reliable operation
Why choose this principle:
The harmful component (chips mixed in coolant liquid) is extracted from the system by creating a separate discharge path that bypasses the hand member driving mechanism. The coolant liquid is discharged through discharge ports away from the critical gripping components, eliminating the clogging problem.

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.
