Title:
POINT TOOL MOUNTING DEVICE
Document Type and Number:
Japanese Patent JPH06226705
Kind Code:
A
Abstract:

PURPOSE: To miniaturize a clamping fixture, make the independent clamping fixture unnecessary and prevent a collet from being broken by a method wherein the clamping and unclamping of a collet chuck is performed under the condition that a gear-like indentation and a pinion-like indentation are engaged with each other after the fixing of the collet with a collet fixing tool.

CONSTITUTION: In the point tool mounting device concerned, by pressing a handle 10 to a router main body 1 side, a fixing tool 3 is shifted so as to fix a collet 2 and, at the same time, a pinion-like indentation 7 is engaged with a gear-like indentation 5 provided on the outer periphery of a chuck 4. Further, by applying torque through a hinge 9 through the pivoting of the handle under the condition that both the indentations are engaged with each other, the clamping and unclamping of the collet 2 and the chuck 4 through the pivoting between the gear-like indentation 5 and the pinion-like indentation 7. After a bit tool 11 is clamped. by putting the handle 11 back in its initial position, the pinion-like indentation 7 is disengaged from the gear-like indentation 5 and the fixing tool 3 is also parted from the collet 2, resulting in making the bit tool 11 rotatable and bringing it into the state ready for cutting operation.
