This cutter head 10 is one of the face milling cutters, has three claws n, and each claw "locks a blade 12 to act as Cutting edge use. A coupling section 13' protruding from the back of the claw n is joined to the shank 2 by the screw 14 of the shaft portion of the cutter head 1 (). This knife is capable of 2G crimes. The knife is extended at the 1Q position—the head section u, and the to-be-fastened part 22 around the knife pole 2 is adjacent. The head section 2; the second pole: is coupled to the tail section 23 of the cutter bar 20, and is combined with the cutting output (not shown) power output end. When the knife is in the middle, the workpiece exerts a reaction force on the tool 1 〇 ,, resulting in a continuous shock, which has a serious adverse effect on the cutting precision and quality. 5 / 曰 1 Figure 曰 另 Another alternative tool for turning or boring 100, has paid for the # new certificate No. M2931 〇 3 patent, revealing a knife 3

Too many: the two places to slow down the momentum, the [new content] r problem in view of this 'this creator in-depth discussion of the prior art and years of experience in the research and development of related industries and actively seek solutions, finally succeeded Developed a shock absorbing arbor, 'to improve the problem of custom creation. One of the purposes of this creation is to use a guiding method to perform a shock absorbing motion along the axial direction of the tool shaft axis to the outer surface, thereby reducing the amplitude of the shaft vibration relative to the increase and precision. One of the purposes of this creation is to eliminate the need for shock absorption and to quickly complete the assembly of the shock absorbing shank. One of the purposes of this creation is that fewer components are included in the damper device. The manufacturing cost is much lower than the M293103 patent. Due to the above objectives, the present invention provides a shock absorbing arbor, and a shock absorber is arranged inside the eccentricity of a shank. The damper seals a stud in a spiral groove located inside the arbor. The stud is spaced from the wall surface of the spiral groove by a predetermined distance and is recessed into a rectangular groove at the end face. The spiral groove opening seals a cover sheet, and the cover sheet protrudes from a rectangular ridge, and the concave and convex fits into the groove of the stud. The two short sides of the ridge are each directed toward the axis of the arbor and the outer surface of the shank, and the column must not be rotated in the spiral direction while guiding the stud to perform inertia along the length of the ridge. ^The created shock absorbing shank, the guiding stud (ie, the damper) moves in a linear direction along the axis of the arbor to the outer surface according to the inertia, thereby striking the opposite wall of the snail, reducing the force of the workpiece against the arbor, At the same time, the amplitude of the shaft caused by the cutting operation is reduced, and the precision of machining is relatively improved. Thus, the components of the entire damper device are less. To reduce the cost of production, there is no need to adjust the damping force, and the assembly of the arbor is naturally completed quickly. M419623 Regarding the techniques, means and functions of this creation, the following examples are given in detail with the drawings. I believe that the purpose, structure and characteristics of this creation 1 can be obtained from an in-depth and specific understanding. . [Embodiment] As shown in Fig. 3, the shank 4 is a cone, and a trailing end 41 is formed at the small end, which can be coupled to the power output of the milling device (figure, 曰). Extending around the large diameter end of the shank 4G °\42 extends outward from the to-be-fastened portion 42 - a cylindrical connecting section. The end face of the engaging portion 43 is immersed in a shaft groove 44 for combining the (9) cup 50' and sealing the shock absorber 60 of the damper 4th edge from the portion away from the axial groove 44, The stud 61 is placed in a spiral groove recessed in the eccentric position of the end face of the engaging section 43. The stud 1 has a slight distance from each circumference around the spiral groove 45. The spiral groove 45 is deep into d = the bottom of the groove, and the notch is located at the end face of the engaging portion 43; the means is combined into a body, so that the stud 61 is tightly sealed with the inside of the groove 45 and is not detachable. The mountain seal is merged in the rectangular recess 64 in which the screw red 62 61 is placed, and the end surface of the 61 is opposite to the position portion 63, causing the mast 61", the length of the groove 64 to be longer than the length of the ridge back to the third ridge portion 63. := Look:: The head 5° is the diameter equal to the connecting section. The surface is extended—the one pole section 5 and the other end section 6 two exits the 1 section 53. The joint section 43 is locked by the rod section 51. The groove 44 is such that the head 5G abuts against the engaging portion 43 and the welding is connected to the second Si: forming a ring of solder 52, which is sufficient for the shock to be completed, so that the stud 61 is sealed inside the shaft Eccentricity.—4 7 The 'screw section 53 is selectively inserted into any of the 搪=7〇, the milling head 71 or the ore cutter head 72, and is fastened by a screw 73 to complete the entire set of tools. ', , cutting operation, the cutter head touches the workpiece to the cutter bar 4 〇 ° as shown in Figures 5, 6 and 8, the cover plate 62: two:: the index groove 65 of the ridge portion 63, The ridge 4 〇ΓΓΓ is oriented toward the axis of the arbor 40, and the other short side faces the outer surface of the arbor. Thus, the ridge 63 limits the rotation of the stud in the spiral groove 45, while guiding the stud 61 along the prolongation Back and forth, the opposite wall of the spiral groove 45 of the child hits: The force that causes the earthquake to dampen the two sides, which reduces the amplitude of the shaft in response to the cutting work, and relatively improves the processing of the customer. The cost of the heart m. And the 'damper 60 does not have to be reduced' is enough to quickly complete the assembly of the tool bar 40. According to the above configuration, other embodiments can be derived. The difference between the tool bar 40' and the foregoing embodiment is ^ (9) The number is increased by three times. In other words, three sets of dampers 60 are arranged beside the axial groove 44 of the shank 4 =: each cover Si3 Γ knows that each set of dampers 60 is from the axial center of the arbor 40 = The table is linearly displaced to reduce the vibration amplitude of the shaft. The above examples are only for the purpose of explaining this creation, and are not intended to limit the creation. The various changes and applications derived from the above embodiments are within the scope of this creation.
