Abstract
The present disclosure relates a chain sharpening jig as well as method of using an existing chainsaw sharpener for machining tooth profile of chainsaw chains. The chain sharpening jig includes a slide base configured to be clamped to a universal chainsaw sharpener. A slide clamp is slidably arranged on the slide base. A chain holder is connected to the slide clamp and the chain holder is configured to receive the chainsaw chain. The chainsaw chain is configured to be machined by the grinding wheel of the universal chainsaw sharpener.
Claims14
A chain sharpening jig (10) configured to be removably attached to a universal chainsaw sharpener (100), the chain sharpening jig (10), comprising:
- a slide base (30) comprising a tab portion (32) configured to be clamped inside a drive link clamp (110) of the universal chainsaw sharpener (100);
- a slide clamp (50) arranged on the slide base (30);
- a chain holder (70) connected to the slide clamp (50);
- wherein the chain holder (70) comprises:
- a first element (74), a second element (78), and a third element (82) positioned between the first element (74) and the second element (78);
- wherein the third element (82) is connected to each of the first element (74) and the second element (78) to form a groove (82);
- wherein the groove (82) is formed on the exterior surface of the third element (82) between the first element (74) and the second element (78);
- and
- wherein a chainsaw chain (20) to be machined is arranged in the groove (82);
- and a grinding wheel (120) of the universal chainsaw sharpener (100) is configured for machining the chainsaw chain (20) arranged in the groove (82).
A method of machining a chainsaw chain (20) by utilizing a universal chainsaw sharpener (100), the method comprising the steps of:
- providing a chain sharpening jig (10), wherein the chain sharpening jig (10) comprises:
- a slide base (30) removably connected to a drive link clamp (110) of the universal chainsaw sharpener (100);
- and a chain holder (70) which further comprises:
- a first element (74), a second element (78), and a third element (82) positioned between the first element (74) and the second element (78);
- wherein the third element (82) is connected to each of the first element (74) and the second element (78) to form a groove (82);
- wherein the groove (82) is formed on the exterior surface of the third element (82) between the first element (74) and the second element (78);
- removably attaching a chain sharpening jig (10) to the universal chainsaw sharpener (100);
- placing the chainsaw chain (20) to be machined into the groove (82) of the chain sharpening jig (10);
- positioning a grinding wheel (120) of the universal chainsaw sharpener (100) in close proximity of the top of the chain holder (70) in a generally vertical state such that the rotational axis of the grinding wheel (120) is substantially parallel to the longitudinal axis of the slide base (30);
- and
- bringing the grinding wheel (120) towards the chainsaw chain (20) in a substantially vertically downward direction to thereby contact against tooth of the chainsaw chain (20).
