In my device a tapered drift pin is disposed in said slot and, under the control of manually operable means, bears against said tip and forces same outward in the bore, thus releasing the tool from the spindle without damage either to spindle or tool.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:
FIG. 1 is a side view of one form of my invention;
FIG. 2 is a top view thereof;
FIG. 3 is a view through 3-3 in FIG. 1; and
FIG. 4 is a side view of a modification of my invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring to FIGS. l-3, a spindle has a tapered bore 12 in which is set a tapered tool 14. Spindle 10 has a transverse slot 16 extending therethrough perpendicular to the bore and communicating with the inner end of the bore. The tip 18 of one end of the bore extends out of the inner end of the bore into the slot.
A flat plate 20 has upper and lower curved extensions 22 and 24 which encircle partially and support the spindle in vertical position. A transverse shaft 26 spring loaded at 28 extends out of the plate. The other end of the shaft extends through an offset hole in the head 32 of lever 34, lever 34 being rotatable about the shaft. A tapered drift pin 36 can be disposed in the slot. As the pin is pushed through the slot, its downwardly extending bottom surface pushes downward against tip 18 to push tool 14 out of the spindle without damaging spindle, tool or pin.
The head of pin 36 has a curved surface 30 engaging the eccentrically curved surface 38 of head 32 whereby swinging the lever 34 by manual action from the solid line position of FIG. 1 to the dotted line position forces the pin inward through the slot. Teeth 40 on the inside of plate 41 secured to the lever can engage teeth 42 on the body, the relative positions being manually variable to move the lever closer to the pin as required.
In FIG. 4, pin 36 is secured to a piston 44 in an air cylinder 46 operated by compressed air supplied to hose 48 to move the pin as described above.
While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.
I claim:
1. A device for removing tapered tools from the tapered bore of a spindle, said spindle having a transverse slot exposing the tip of the tool and communicating with said bore, said device comprising a tapered drift pin, means for removably inserting the pin in the transverse slot whereby the pin will bear against the tip of the tool and force the tool out of the bore, said means including a support structure comprising a flat body plate having a longitudinally extending recess therein, a second smaller plate movably mounted in said recess, movable pusher means on said support structure, clamping means compnsmg longitudinally extending portions of the body plate forming vertically spaced apart and horizontally extending arms curved at their ends to form U-shaped clamps for detachable securement to the spindle with the pusher means in alignment with the transverse slot, said pusher means being engageable with the outer end of the drift pin upon insertion of one end of the pin into the transverse slot and comprising a cam structure having an eccentric cam surface pivotally mounted on the support structure by means of a shaft securing said cam structure to said smaller plate, a manually engageable lever attached to the cam structure which, upon actuation, pivots the cam structure thereby moving portions of the eccentric cam surface towards the drift pin to exert an axial force on the drift pin to drive the drift pin into the transverse slot and force the tool but of the bore, and spring means operatively connected between said shaft and said support structure, said spring means biasing the cam structure in a direction to move the cam surface out of engagement with the drift pin.
2. A device as set forth in claim 1 further including means for adjusting the position of the cam member and pin relative to said slot, said means comprising a row of upwardly extruding teeth in the body plate extending longitudinally along a portion of the recess and
Claims (2)
1. A device for removing tapered tools from the tapered bore of a spindle, said spindle having a transverse slot exposing the tip of the tool and communicating with said bore, said device comprising a tapered drift pin, means for removably inserting the pin in the transverse slot whereby the pin will bear against the tip of the tool and force the tool out of the bore, said means including a support structure comprising a flat body plate having a longitudinally extending recess therein, a second smaller plate movably mounted in said recess, movable pusher means on said support structure, clamping means comprising longitudinally extending portions of the body plate forming vertically spaced apart and horizontally extending arms curved at their ends to form U-shaped clamps for detachable securement to the spindle with the pusher means in alignment with the transverse slot, said pusher means being engageable with the outer end of the drift pin upon insertion of one end of the pin into the transverSe slot and comprising a cam structure having an eccentric cam surface pivotally mounted on the support structure by means of a shaft securing said cam structure to said smaller plate, a manually engageable lever attached to the cam structure which, upon actuation, pivots the cam structure thereby moving portions of the eccentric cam surface towards the drift pin to exert an axial force on the drift pin to drive the drift pin into the transverse slot and force the tool out of the bore, and spring means operatively connected between said shaft and said support structure, said spring means biasing the cam structure in a direction to move the cam surface out of engagement with the drift pin.
2. A device as set forth in claim 1 further including means for adjusting the position of the cam member and pin relative to said slot, said means comprising a row of upwardly extruding teeth in the body plate extending longitudinally along a portion of the recess and adapted to engage a row of downwardly extruding teeth extending longitudinally along the smaller plate whereby said smaller plate may be adjusted longitudinally of the body plate.
