Tool extraction system for rotary cutter device
View Patent ↗In one exemplary aspect, an extraction tool adapted for extraction of a cutting tool holder mounted to a rotary member of a rotary cutting device is disclosed. The extraction tool comprises a tool frame. A first extraction wedge and a second extraction wedge are connected with the tool frame. At least one of the extraction wedges is movably connected with the tool frame. A related method is also disclosed. In another exemplary aspect, a method of extracting a cutting tool from a tool holder of a rotary cutting device comprises the steps of positioning an extraction tool adjacent the tool holder with a first end at a positioned forward of a cutting tool surface that is disposed within the tool holder and with a second end positioned rearward the cutting tool surface, and applying force to the first end of the extraction tool in a direction other than perpendicular to a longitudinal axis.
1. An extraction tool configured for extraction of a cutting tool holder mounted to a rotary member of a rotary cutting device, the extraction tool comprising:
a tool frame;
a first extraction wedge connected to the tool frame, the first extraction wedge including a first end, a central portion, and a second end configured for engagement against a first surface of a cutting tool holder;
a second extraction wedge connected to the tool frame in a position spaced from the first extraction wedge, the second extraction wedge including a first end, a central portion, and a second end configured for engagement against a second surface of a cutting tool holder;
wherein at least one of the extraction wedges is connected adjacent its central portion for pivotal and linear movement relative to the tool frame.
2. The extraction tool of claim 1 , wherein each of the first extraction wedge and the second extraction wedge is connected for pivotal and linear movement relative to the tool frame.
3. The extraction tool of claim 1 , wherein the at least one wedge connected for pivotal and linear movement relative to the tool frame includes an elongate slot.
4. The extraction tool of claim 1 , wherein the at least one wedge is removable from the tool frame.
5. The extraction tool of claim 1 , further including a handle assembly extending from the tool frame.
6. The extraction tool of claim 5 , wherein the handle assembly is swivelably connected to the tool frame.
7. The extraction tool of claim 5 , wherein the handle assembly includes an elongate shaft.
8. The extraction tool of claim 1 , wherein the tool frame includes first and second clevises, and wherein the first extraction wedge is connected to the first clevis, and the second extraction wedge is connected to the second clevis.
9. The extraction tool of claim 8 , wherein each of the first and second wedges includes an elongate slot, and wherein the extraction tool further includes fasteners connecting each wedge to a respective clevis via one of the elongate slots.
10. The extraction tool of claim 8 , wherein the first and second clevises are laterally spaced apart on the tool frame, and a handle assembly is swivelably connected to the tool frame at a position on the tool frame that is centrally located relative to the first and second clevises.
11. A service tool kit for a rotary cutting device, comprising a tool holder extraction tool and a cutting tool extraction tool wherein:
the tool holder extraction tool includes:
a tool frame;
a first extraction wedge connected to the tool frame, the first extraction wedge including a first end, a central portion, and a second end configured for engagement against a first surface of a cutting tool holder;
a second extraction wedge connected to the tool frame in a position spaced from the first extraction wedge, the second extraction wedge including a first end, a central portion, and a second end configured for engagement against a second surface of a cutting tool holder;
wherein at least one of the extraction wedges is connected adjacent its central portion for pivotal and linear movement relative to the tool frame, and
the cutting tool extraction tool includes:
an elongated shaft extending from a first end to a second end and including:
a first linear section extending from the first end:
a second linear section extending from the second end: and
an arcuate section joining the first and second linear sections,
wherein the elongated shaft tapers over a portion of the arcuate section and at least one of the first and second linear sections; and
a grip provided on the shaft near the first end.
12. The service tool kit of claim 11 , wherein the tool frame of the tool holder extraction tool further includes first and second clevises, and wherein the first extraction wedge is connected to the first clevis, and the second extraction wedge is connected to the second clevis.
13. The service tool kit of claim 12 , wherein each of the first and second wedges includes an elongate slot, and wherein the service tool kit further includes fasteners connecting each wedge to a respective clevis via one of the elongate slots.
14. The service tool kit of claim 12 , wherein the first and second clevises are laterally spaced apart on the tool frame, and a handle assembly is swivelably connected to the tool frame at a position on the tool frame that is centrally located relative to the first and second clevises.
15. The service tool kit of claim 11 , wherein the first end of the shaft is not covered by the grip, and wherein the grip is formed of one of rubber and plastic.
16. The service tool kit of claim 11 , wherein the elongated shaft tapers from the first end to the second end.
