Drill-tip sharpening apparatus |
摘要 |
<p>A drill-tip sharpening apparatus which facilitates attachment/removal of a drill. In an attachment (12) of the drill-tip sharpening apparatus, a pair of phase rotation rollers (54) rotatably attached to a main block (50) supports the shank portion of the drill (18), while a body receptor that is provided on a main plate (20) in a vertically movable manner supports the body portion of the drill (18). A shank pressing member (70) is swingably provided on the main block. Through operation of a shank pressing cylinder (48), the shank pressing member (70) swings to hold and release the drill (18) in cooperation with the phase rotation rollers (54). A tip end positioning motor (44) moves a positioning spindle (86) via a drive gear (84) and a slide gear (88) in order to move the drill in the axial direction. A phase adjustment motor (46) rotates a drive roller that is in contact with the phase rotation rollers (54), thereby rotating the drill (18) about its axis via the phase rotation rollers. <IMAGE></p> |
