回転工具の加工深さ調整装置
Document Type and Number:
Japanese Patent JP4672604
Kind Code:
B2
Abstract:
A working depth adjusting device (20) includes an adjusting member (21), an intermediate member (22) and an operation member (23). The adjusting member (21) is supported on the front portion of the tool body (2) and movable along the axis (J) of the spindle (8), so that the position of the adjusting member (21) can be adjusted relative to the tool bit (12) with respect to a working depth direction. The intermediate member (22) is rotatably supported on the adjusting member (21). The adjusting member (21) moves in the working depth direction as the intermediate member (22) rotates. The operation member (23) is operable to rotate relative to the intermediate member (22) between a lock position and an unlock position. The intermediate member (22) has an engaging member (24). When the operation member (23) is rotated to the lock position, the engaging member (24) engages the tool body (2), and the engagement of the engaging member (24) is maintained by the operation member (23), so that the working depth adjusting device (20) can be prevented from being removed from the tool body (2). When the operation member (23) is rotated to the unlock position, the engaging member (24) is disengaged from the tool body (2), so that the working depth adjusting device (20) can be removed from the tool body (2).
