Abstract
A contouring and threading attachment for use with numerically controlled multi-function machine tools having automatic tool changing capability. The attachment has a spindle-actuated body adapted to detachably engage an adapter collar rigidly fixed to the outer end of the spindle sleeve. The body may be installed and removed by the automatic exchange arm mechanism of the machine tool and be stored in the tool magazine when not in use. A cutting tool on the outboard end of the attachment is movably radially of the spindle axis. The radial movements of the cutting tool are executed automatically through corresponding axial movements of the spindle under the numerical control of the machine tool.
Claims7
A contouring and threading attachment for use with a numerically controlled multi-function machine tool having an automatic tool changer including a tool exchange arm with a tool gripper, said machine tool also having a spindle sleeve and a spindle mounted therein for rotation bodily therewith and for axial movement with respect thereto, said spindle having a tool engaging socket therein, said attachment comprising, in combination:
- (a) an adapter collar mountable rigidly on the spindle sleeve of said machine tool for rotation bodily therewith;
- (b) a body having a central axial bore therein and adapted to detachably engage said adapter collar for rotation in unison therewith;
- (c) an actuating bar housed telescopically within said central bore of said body and movable axially of said bore;
- (d) said actuating bar having an inner end portion, an intermediate portion, and an outer end portion;
- (e) said inner end portion of said actuating bar being insertable in the spindle socket for driving connection therewith rotationally and axially;
- (f) a transverse flange on said intermediate portion of said actuating bar engageable by the gripper of the tool exchange arm acting between said body and said adapter collar;
- (g) a radial tool slide adjustably mounted on the outboard end of said body;
- and
- (h) means defining a motion transmitting connection between said tool slide and said outer end portion of said actuating bar;
- (i) means for releasably latching said actuating bar in a fixed position with respect to said attachment body to facilitate storage and transfer of said attachment to and from the spindle by the tool exchange arm;
- and
- (j) detent means for disengaging said releasable latching means upon engagement of said body with said adapter collar, and for engaging said releasable latching means upon disengagement of said body from said adapter collar.
A contouring and threading attachment for use with a mechanically controlled multi-function machine tool having an automatic tool changer including a tool exchange arm with a tool gripper, said machine tool also having a spindle sleeve and a spindle mounted therein for rotation bodily therewith and for axial movement with respect thereto, said spindle having a tool engaging socket therein, said attachment comprising, in combination:
- (a) an adapter collar mountable rigidly on the spindle sleeve of said machine tool for rotation bodily therewith;
- (b) a body having a central axial bore therein and adapted to be detachably coupled to said adapter collar for rotation in unison therewith;
- (c) an actuating bar housed telescopically within said central bore of said body and movable axially of said bore;
- (d) said actuating bar having an inner end portion, an intermediate portion, and an outer end portion;
- (e) said inner end portion of said actuating bar being insertable in the spindle socket for driving connection therewith rotationally and axially;
- (f) means on said intermediate portion of said actuating bar engageable by the gripper of said tool exchange arm acting between said body and said adapter collar;
- (g) a radial tool slide adjustably mounted on the outboard end of said body;
- (h) means defining a motion transmitting connection between said tool slide and said outer end portion of said actuating bar;
- (i) means for releasably latching said actuating bar in a fixed position with respect to said attachment body to facilitate storage and transfer of said attachment to and from the spindle by said tool exchange arm;
- and
- (j) said releasable latching means further comprising a detent pin and cooperating shot pin, the latter being interposed between said body and said actuating bar.
A contouring and threading attachment for use with a numerically controlled multi-function machine tool having an automatic tool changer including a tool exchange arm with a tool gripper, said machine tool also having a spindle sleeve and a spindle mounted therein for rotation bodily therewith and for axial movement with respect thereto, said spindle having a tool engaging socket therein, said attachment comprising, in combination:
- (a) an adapter collar mountable rigidly on the spindle sleeve of said machine tool for rotation bodily therewith;
- (b) a body having a central axial bore therein and adapted to detachably engage said adapter collar for rotation in unison therewith;
- (c) locking means interposed between said body and said adapter collar for detachably coupling same together when said body is in abutting engagement with said adapter collar;
- (d) said locking means comprising a stud cam fixed to said body and a resiliently biased automatic cam journaled in said adapter collar, said cam members being engageable as an incident to movement of said body into contact with said adapter collar;
- (e) an actuating bar housed telescopically within said central bore of said body and movable axially of said bore;
- (f) said actuating bar having an inner end portion, an intermediate portion, and an outer end portion;
- (g) said inner end portion of said actuating bar being insertable in the spindle socket for driving connection therewith rotationally and axially;
- (h) means on said intermediate portion of said actuating bar engageable by the gripper of the tool exchange arm acting between said body and said adapter collar;
- (i) a radial tool slide adjustably mounted on the outboard end of said body;
- (j) means defining a motion transmitting connection between said tool slide and said outer end portion of said actuating bar;
- (k) means for releasably latching said actuating bar in a fixed position with respect to said attachment body to facilitate storage and transfer of said attachment to and from the spindle by said tool exchange arm;
- and
- (l) said releasable latching means further comprising a detent pin and cooperating shot pin, the latter being interposed between said body and said actuating bar.
