た平面切削工具に関するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention is a tool that replaces a socket milling tool, and is a tool that uses radial grooves provided on the surface of a circular seat plate that is integral with a shaft rod to be chucked. The present invention relates to a flat cutting tool in which a support rod to which a chip is detachably fixed is detachably fixed.

としては、このようなバイト固定手段を利用する
ことができないものである。(Problem to be Solved by the Invention) The former cutting tool is for hole machining, but it is a tool that fixes a cutting tool with an integrated cutting blade by adjusting and changing the rotation trajectory of the cutting edge. This is convenient when the dimensions of the cutting edge change due to polishing or when cutting holes with slightly different diameters, but since the cutting tool is only fixed by pressing it in the right angle direction with screws on both sides, the cutting edge If a cutting force is applied to the part, not only is there a risk of causing vibrations using the pressing and fixed part as a fulcrum, but also because the cutting force does not act in the axial direction of the rotating shaft with this tool, the force in that direction is If this occurs, there is a disadvantage that the cutting tool may come off. For this reason, such a cutting tool fixing means cannot be used as a mounting structure for a flat cutting tool in which a force in the axial direction of the rotating shaft acts on the cutting blade.

くなる欠点がある。 In addition, the latter type of flat cutting tool uses a removable tip as the cutting blade, making it easy to replace the tip. Therefore, when changing the cutting size, not only the locator but also the chuck must be replaced with a seat with a different shaft diameter. However, since the screw is perpendicular to the groove bottom, the fixing force is weak, and the cutting force acting on the chip tends to cause vibrations, similar to the hole cutting tool described above.

ている。 In view of the above-mentioned drawbacks of the prior art, the present invention enables the support rod to which the chip is removably fixed to the seat part to be fixed easily and reliably to the seat, and has a wider diameter than the standard holder diameter and shaft rod. It is an object of the present invention to provide a flat cutting tool capable of cutting a wide surface and easily and reliably replacing teeth for adjusting the cutting width.

Since the cylinder 11 is arranged at the center of the seat part 8 or on a concentric circle with the center, and the support rod A and the inclined abutting surface 2 are provided, the center of the holder B and the tip C are arranged with respect to the rotation direction of the holder B. Behind the line connecting
The contact surface 2 of the support rod A comes into contact with the contact point 11A of the cylinder 11, and is wedged between the cylinder 11 and the side wall of the mounting groove 10 and is firmly fixed, so that the holder B does not swing, and The force applied to the tip C during cutting can be dispersed to the contact point 11A of the cylinder 11 of the support rod A and the horizontal groove of the holder B.
There is no vibration, the durability of the chip C is improved, and the cutting surface becomes clean.

平面切削工具。 1. In order to fix the cutting blade to the tip of each mounting groove 10 of the holder B, which has a plurality of mounting grooves 10 radially carved parallel to the radial center line on the surface of the seat 8 integral with the shaft rod 9. In the plane cutting tool in which the support rod A is fixed, the holder B fixes the cylinder 11 at the center of the seat part 8 where each mounting groove 10 gathers or on a concentric circle with the center, and also A fixing screw 14 is screwed into a screw hole 13 that is passed through the inner surface of the mounting groove at an angle such that the tightening force of the fixing screw acts toward the center of the seat. is an oblique contact surface, and a locking hole 3 is provided in the middle part of the rod part 1 to which the tip of the fixing screw 14 comes into contact, and the other end is used as a head part 5 for fixing the tip. The tip C is detachably fixed to the head 5 at the tip of A itself, and the support rod A to which the tip C is fixed is provided with an inclined abutment surface 2, so that the direction of rotation of the holder B is referenced. The contact surface 2 of the support rod A contacts the cylinder 11 behind the line connecting the center of the holder B and the chip C, and the force applied to the chip C during cutting is transferred to the contact point 11A of the cylinder 11 of the support rod A. A flat cutting tool characterized in that the cutting tool is fitted into each mounting groove 10 in a dispersed state in a horizontal groove of a holder B, and is fixed by the fixing screw 14.
