Description of the Invention: [Technical Field] The present invention relates to a machine tool, and more particularly to a tool-tool-cutter-incremented bore-hole holder device which has a good fixing effect and can reduce the chance of vibrating the knife. [Prior Art] Referring to Fig. 1, a general cutter lathe device 1 is disposed inside a CNC lathe, and a rotary shaft 11 is disposed at the center of the cutter disc device 10. The cutter disc device 10 can be rotated around the rotary shaft 11 and the cutter disc A plurality of Ο mounting faces 12 are arranged on the outer periphery of the device 1 , and a plurality of different types of knives 13 are mounted on the mounting surface 12 ′′, wherein a shank 14 is locked and fixed on a mounting surface 12 , and one of the knives 14 A mounting hole 141 is recessed in the side surface, and a rear end of the inner hole cutter 15 is sleeved and locked in the mounting hole 141, and a front end of the inner hole cutter 15 extends for a predetermined length to extend into a workpiece (not shown). For inner hole machining operations. The general bore cutter 15 has a long suspension length, and it is easy to affect the accuracy of the workpiece due to the vibrating cutter when cutting. Therefore, the fixed position of the bore cutter 15 should be closer to the cutter device 10, but the conventional cutter disc is better. The device 1〇® often has a rather troublesome problem in use. Referring to Figure 2, when the cutter unit 10 is to be installed with a large bore tool 16, it needs to be fitted with a larger seat 17'. It is fixed on the mounting surface 12, and the tool holder 17 is recessed with a mounting hole 171 for the large internal hole cutter 16 to be inserted. The center of the mounting hole 171 is displaced in the direction away from the cutter device 10 due to the large aperture relationship. A distance D' will increase the chance of the large bore tool 16 vibrating knife, reducing tool life and workpiece accuracy. SUMMARY OF THE INVENTION 200938331 Accordingly, it is an object of the present invention to provide an enlarged internal bore holder device for a machine tool cutter with a stable bonding force and an effective reduction of the vibrating cutter.

The base 33 protrudes from the bottom of the holder 31. A convex portion is provided, which can be wedged with the (four) groove 24 of the mounting surface 23, and can increase the contact area between the knife seat 31 and the mounting surface 23. Further extending the two wings 312, the wings 312 are inclined to the adjacent mounting surface 23, and then the locking screws 33 are inserted into the wings 312 to be locked on the mounting surface 23, so as to fix the whole The holder 31 is on the cutter head 21. The tool holder 31 has a side surface 313 on which a mounting hole 314 for the tool % is drilled. The tool 32 refers to a large inner hole machining tool 'the tool holder 3' extending downwardly. The convex portion 311 can expand the area of the side surface 313, whereby the aperture of the mounting hole 314 of the blade holder 31 is enlarged, and the center of the mounting hole 314 is narrowed toward the cutter head 21 rather than away. The above is an overview of the shape and combination type of each member of the tool hole cutter device of the present invention; and then, the effect of the invention can be achieved as follows: (1) _ binding strength is stable: The holder 31 of the present invention is wedged by the convex portion 311 and the groove 24 on the cutter head 21, so that the contact area between the two can be enlarged, and the two wings 312 of the holder 31 are further attached to the adjacent installation. In the facet, the entire seat 31 can be firmly engaged on the cutter head 21, and then the two fixing screws 7 200938331 wire 3 3 are used for locking, and the bonding force is quite stable. Mountain (2). Reduced vibrating knife opportunity: After the blade seat 31 of the present invention is wedged with the knives 311 by the convex portion 311, the convex portion 311 penetrates the mounting hole 314 on the blade seat 31 in the relationship inside the cutter head 2丨. The center will move closer to the cutter head 21, so that the present invention makes the cutter 32 as close as possible to the knife #2, and the vibration knife is not easy to be generated. Therefore, the present invention can effectively improve the tool life and workpiece accuracy.
