工具切刃にチッピングが発生する欠点がある。As shown in Figure 1, the holder is a typical conventional holder for holding rotary tools with straight shanks such as drills, end mills, and reamers used in machine tools for metal processing. A taper collet (4) that grips the straight shank (3) of the tool (2) on the main body (1)
(!: , Oak that tightens the taper collet) (5)
There is something that has Th. This one has a taper collet (
4) The gripping force is very weak because the thrust load and cutting torque are applied only to the collet, and if an excessive thrust load or large cutting torque is applied during cutting, the shank of the tool will slip inside the taper collet and the holding force will be lost. However, there is a drawback that the tool may be pushed in 1n or chipping may occur on the cutting edge of the tool.

きないので、工具突出量を調整することはできない。In order to compensate for these drawbacks, a rotary tool holder shown in FIGS. 2 and 3 is used. In this tool, the shank part (6) of the holder body (1) has a drive piece that receives the cutting torque of the tool (an adjustment screw (8) that receives the force and thrust load and adjusts the protrusion amount of the tool) that completely passes through the center hole.
is inset. The drive piece (7) is provided with an insertion groove α1 into which a tank (9) provided at the rear of the straight shank (3) of a drill with a particularly large thrust load or cutting torque is inserted. '+'+
:N, both ends of the bottle are inserted into key grooves α bored in the axial direction in the shank part (6) of the main body, so that they support cutting torque and can move along the key grooves α. ing. Attach the tool (2) to the tank (9) and the rad drive piece (
Since it is inserted into the insertion groove α1 of 7) and fixed by tightening with the taper collet (4), it can sufficiently support the thrust load and cutting torque, unlike the holder shown in Fig. 1, which is held only with the taper collet (4). I can do it. However, when used while attached to a machine, if the tool becomes worn or damaged during cutting, the tool can be replaced with the tool holder (1) attached to the machine, but the adjustment screw (8) fr: external It is not possible to adjust the tool protrusion amount.

When used in transfer machines, etc. used in the automobile industry, presetting is difficult because tools cannot be replaced or adjusted on the machine. Also, the drive piece (7) bottle Ql) n As mentioned above (D), the keyway (12) moves freely and supports the cutting torque, but if the outer diameter of the drive piece housing becomes smaller, the strength will be reduced by the amount of the keyway provided. It has major disadvantages such as small size and lack of rigidity, which imposes restrictions on manufacturing.
