Abstract
A deburring tool includes: a body; and a cutting unit provided on an end portion of the body and including a blade part, where a first channel is provided inside the body, and when a fluid supplied from outside of the deburring tool through the first channel is injected into the cutting unit and presses the cutting unit, the cutting unit moves and a degree to which the blade part protrudes outwardly increases.
Claims14
A deburring tool, comprising:
- a body;
- a cutting unit provided on an end portion of the body and including a first surface and a second surface, wherein the first surface of the cutting unit includes a blade part which performs cutting by contacting an area to be cut,
- a first channel provided inside the body,
- a head coupled to the end portion of the body in a longitudinal direction of the body, wherein the cutting unit is mounted on a recessed portion of the head,
- a second channel provided inside the head, and in communication with the first channel, the second channel including:
- a first end portion adjacent to the first channel,
- a second end portion adjacent to the second surface of the cutting unit, and
- further comprising a shaft passing through side surfaces of the cutting unit,
- wherein, when a fluid supplied from outside of the deburring tool through the first channel is injected into the cutting unit and presses the cutting unit;
- the fluid passes through the first channel and the second channel and is injected into the second surface of the cutting unit,
- the cutting unit rotates with respect to the shaft, and
- a degree to which the blade part protrudes outwardly increases.
