These tool openings are simple cutting elements, the overall structure does not allow any vibration reduction, and how to reduce the degree of tool vibration becomes a problem to be overcome. In particular, the boring tool required for the aperture expansion operation enters the work. The deeper the inside, the stronger the vibration of the blade is, which is not conducive to energy and labor. 135 Fuzha knife and horse are two parts of the known technology. The female knives 1 and the boring knives 10 made up of a shaft u are combined with a head 12 to form a 12-mounting blade 13 and the blade 13 is offset from the middle of the shaft 11. The shaft 11 faces the end of the head 12. As the front end, an end m conical recess 14' is formed and the head 12 defines an "in" shape toward the axis u. The 81 conical projection 15 extending rearward is inserted into the concavity 14 of the crucible. The concave portion 14 and the convex portion 15 are provided with a complementary η 1 mountain over-expanding adhesive, so that the head 12 is fastened to the shaft 1 and is not separable. However, the blade 13 wears in response to cutting. 201228752 To be unbearable, it is necessary to discard the old tool and replace it with a new one. This not only wastes resources, but also increases the cost of labor, and it is necessary to improve it. In view of this, the inventors have in-depth discussion of the problems of the prior art. Yasu has been engaged in research and development and manufacturing experience of the industry for many years, and actively seeks solutions, and finally developed a boring knife to change the type of the problem. . Self-use new [Summary of the Invention] The main purpose of the present invention is to make a tool holder by using different materials f and vibration mitigation 5, to install the required head, to be detachable and replaceable, to discard the entire tool, and to save resources and reduce labor cost. . As a result of the above, the boring tool of the present invention comprises -f 'with a - cutting configuration; - a shank for detachable head (4). We (1) private, including a base, having a front end; a damper, and::: end and a rear end 'in the front end into a screw groove, the groove is internally rotated; ^ main' studs alternately collide with the snail The opposite wall of the groove, the rear end and the front end of the base are combined into a body; a cover:: = = into a confined space, locking the head, * part; base?

[Embodiment] 凊 Refer to Figures 2 and 3, - Combination boring cutter 2 (), lock one end 21 at the end of the shank 3G 'Removal and replace other heads as needed 2 Do not discard the entire knives It has the effect of saving resources and reducing labor costs. The head 21 carries a cutting configuration, such as a blade 22, secured to the corner of the head 21 by one of means such as welding or screwing, and the blade 22 is offset from the central axis of the shank 30. The head 21 extends through a first flow path 23, with one side leading to the blade 22 being regarded as an outlet 25, the side defining the connecting shank 3's as an inlet 26, and two notches 27 rising outward in the radiation direction around the wall of the inlet 26. The head 21 is locked to the end of the shank 30 by three screw members 28, and the screw members 28 pass through the head 21 without damaging the first flow path 23 and the bump 27. The shank 30 is divided into three sections of different materials, and includes a base portion 31, a damper portion 40 and a cover portion 5 〇, which are welded to each other in a cylindrical shape. The 201228752 shaft body' surface is surface-treated to form a flat circumferential surface. The base portion 31 is a rigid carbonized chicken, and the end portion of the damper portion 4 〇 "below the rear end portion" adjacent to the damper portion 4 视为 is regarded as a front end 'shaped at the front end - a conical convex portion 32 that is contracted forward. The conical surface is arranged with a desired soldering agent 33, such as silver-chromium solder. The base portion 31 is formed by a vertically and horizontally communicating hole - a second flow path 34 in which the longitudinal contact hole is directly connected to the rear end of the base portion 31 from the axial center of the convex portion 32. The hole in the axial center of the convex portion 32 is inserted into the leak stop ring 35, and the opening at the rear end of the exposed base portion 31 is sealed by a stopper bolt 24, so that the high-pressure coolant can be turned to the hole H. The horizontal hole is sealed, and the cooling liquid is changed from the longitudinal hole to the inside of the shank 3. The damper portion 40 is made of hard alloy steel, and the base 31-end is defined as a rear end to abut the cover 5G. The end is regarded as the front end. A conical recess 41 is formed at the rear end of the damper portion 40 to cover the convex portion 32, and the complementary concave, convex conical surface, the central portion of the base portion 40 and the base portion are used. The combination of the damping surface is strengthened by the soldering agent 33. The screw is recessed in the front end of the damper portion, A stud 43 is screwed into the groove, and a gap of about 〇〇1~〇5 _ is retained between the stud 43 and the wall of the groove to fill a portion of the liquid damping agent 44, such as eucalyptus oil or anti-vibration oil, etc., the stud 43 has a hollow design with a consistent perforation... the in-hole insert-tube member 46' abuts against the leak-stop ring 35 through the nozzle at the bottom of the screw groove 42 and directly communicates with the second flow passage 34 of the base portion 31, the liquid flow to the tube member 46. Extending the nozzle outside the stud 43. 7 The pipe member 46 is formed in the screw groove 42 to form another pipe, and the damping agent 44 is not allowed to be mixed in the coolant. Moreover, the outer wall of the pipe member 46 and the stud 201228752 43 shell perforation 45 The wall surface is separated by a predetermined distance, which is larger than the wall surface of the screw groove 42 and the stud: the gap between the three sides does not interfere with the vibration reduction of the stud 43. The cover portion 50 is designed to be the same as the material of the vibration damping portion 40. The plug screw groove 42 is opened to form a closed space, and the other end surface of the field shank 304 is recessed with three rear grooves 5丨, and the corresponding bump 27 is supported by the concave and convex portions, and the head 21 is locked to the cover portion 5 〇, the head 21 cannot be rotated relative to the shank 30. A shaft hole is penetrated through the shaft center of the cover portion 50 to facilitate the protrusion of the tube member 46 through the shaft hole 52. Outside the portion 50, the inlet 26 of the first flow passage 23 of the same day/wood inlet 21 directs the cooling liquid to be ejected from the outlet 25. Further, a gasket 53 is sandwiched between the lid portion 5 and the head 21, and the gasket 53 is fitted over the tube member 46. Externally, the gap between the inlet 26 and the shaft hole 52 is blocked to prevent the coolant from leaking out. ^ Then, referring to Fig. 4, the shank 30 causes a chain reaction of 7 studs 43 due to the continuous two-member movement due to the cutting operation. According to the inertial force w alternately, the wall surface opposite to the screw groove 42 cancels all or part of the kinetic energy of the shank 30 to reduce the vibration damping effect of the shank 30, and the precision of the processing is relatively advanced. The invention is not intended to limit the invention. Various changes, modifications, and applications derived from the above-described embodiments will be apparent to those skilled in the art.
