The bottom of the shank is a set of parts, and the center of the shank is provided with an axial hole extending axially and penetrating the shank; before the shank is connected to the processing machine 10, the bottom of the shank must be heated to promote the positioning of the shank. The shaft hole in the setting part is enlarged. Then, quickly insert one end of the tool into the expanded shaft hole. After the heated part of the tool bar is cooled and cooled, the shaft hole in the setting part will return to the original state. To tighten the tool tightly. However, because the above-mentioned tool bar must undergo repeated changes in thermal expansion and contraction, and must provide a good clamping effect on the tool, the material used for the tool bar itself is relatively special. Generally, the above-mentioned tool bar is relatively expensive. Made of hot mold alloy steel, but the sleeve for clamping the tool only takes up a small part of the overall tool bar volume, so when the tool bar is made entirely of hot mold alloy steel, it is easy Cause increased costs. 20 In view of this, the creators of this case have carefully considered and accumulated many years of research and development experience in related industries, and finally have this creation. [New content] The main purpose of this creation is to provide a separate tool chuck, its ▽ 1 continuation page (when the new instruction page is insufficient, please note and use the continuation page) The new instruction manual continuation page is low cost. The purpose of this is to provide a kind of separate cutter yam head, which can be replaced with a knife of different specifications and sizes in order to achieve the purpose previously disclosed. The separate cutter chuck of this creation includes: There is a tapered hole extending axially inward from one of the end faces; tapered hole: the outer periphery of the knife is tapered inwardly; a clamping member having a cone P at one end and having a sleeve part; The outer periphery is inclined, and the inclination angle of the same is the same as the inclination angle of the taper hole of the shank; the taper is provided on the taper hole of the shank =, and the oscillating portion has a -center hole, and a tool is clamped by heating; The pieces are sleeved on the outside of the wire and screwed to the cutter bar, so that the central holder is positioned on the cutter bar. [Implementation] The structure and function of this creation will be described in detail in conjunction with several preferred embodiments, and the drawings used are briefly explained as follows: The first drawing is a three-dimensional combination drawing of the first preferred embodiment of this creation. The second figure is a perspective exploded view of the first preferred embodiment of the present invention; the second figure is a cross-sectional view taken along the line 2-2 of the first figure; the fourth figure is a sectional view of the second preferred embodiment of the present invention; The fifth figure is a sectional view of the third preferred embodiment of the present invention, and the sixth figure is a sectional view of the fourth preferred embodiment of the present invention. Please refer to the first to third figures for the creation of a separate tool holder. Example # The tool chuck 10 is composed of a shank 11, M253434, a continuation of the new manual, a holder 20, and a Fixing piece 30; Among them: The cutter shaft 11 is made of metal material (for example: carbon steel, chrome molybdenum steel, etc.), and has a shaft hole 12 extending axially downward from the center of the top surface, and the inner end of the shaft hole 12 There is a tapered hole 13 penetrating through the bottom surface of the shank 11; the tapered hole 13 is tapered from the bottom surface of the shank 5; the outer peripheral surface of the bottom of the shank 11 has threads 14; A hollow rod body made of hot-molded alloy steel material with thermal expansion and contraction characteristics, which has a cone portion 21, an elongated sleeve portion 22 and a perforation 23 extending downward from the bottom surface of the cone portion 21; the cone The taper of the outer peripheral surface of the part 21 10 is the same as the angle of inclination of the taper hole 13 of the shank 11. The perforation 23 at the set part 22 is provided for a cutter (not shown) to pass through. The aperture 23 is slightly smaller than the outer diameter of the cutter. . The fixing member 30 is a locking nut in this embodiment. The fixing member 30 has a central hole 31 and a thread 32 on the inner ring wall. 15 With the above structure, the user first applies heat treatment to the sleeve 22 of the clamping member 20 to cause the hole 23 corresponding to the sleeve 22 to be enlarged, and then inserts one end of the cutter into the enlarged hole. In 23, when the clamping member 20 is cooled down and the perforation 23 returns to its original state, the clamping member 20 immediately tightly binds the cutter; then, when assembling and assembling each component, the sleeve 20's sleeve portion is first set. 22 passes through the central hole 31 of the fixing member 30, and thereafter, aligns the cone portion 21 of the clamping member 20 into the tapered hole 13 of the knife rod 11, and the thread 32 of the fixing member 30 and the knife The combination of the thread 14 of the rod 11 and the tightening and upward movement of the fixing member 30 will force the outer peripheral surface of the tapered portion 21 of the clamping member 20 to closely abut the peripheral wall of the tapered hole 13 of the knife rod 11. M253434 The continuation of the manual further achieves that the clamping member 20 and the cutter bar 11 are integrated into one body. In this way, this creation only needs to make the clamping member with a material with good heat expansion and contraction characteristics. At the same time, the clamping member is used in combination with the commonly used cutter bar, which can reduce the cost. 5 The structure of the fixture used to connect the tool bar and the clamping member in this creation can also be replaced by other forms; as shown in the fourth figure, the separate tool chuck 40 of the second preferred embodiment of this creation also includes There is a cutter bar 41, a hollow clamping member 42 and a bolt fixing member 43; the cutter bar 41 has a shaft hole 44 in the center of the top and a tapered hole 45 in the center of the bottom. The 10 shaft hole 44 and The tapered hole 45 communicates; the upper section of the clamping member 42 is inserted into the tapered hole 45 of the shank 41, and a middle portion of the clamping member 42 is a tapered portion 46, and the outer peripheral surface of the tapered portion 46 and the wall surface of the lower section of the tapered hole 45 Abutting, in addition, the upper section of the clamping member 42 has a screw hole 47 drilled from the top to the bottom. The screw hole 47 is used for screwing the lower section of the fixing member 43 into the screw connection. As the fixing member 43 continues to drive to the lower section 15 Penetrating into the screw hole 47 will force the clamping member 42 to move upwards, thereby achieving the purpose of fastening the clamping member 42 in the tapered hole 45 of the shank 41, because the driving method of the fixing member 43 is an existing method The technique is not the focus of this creation, so it will not be repeated; the focus of this embodiment is to explain the use of hot die alloy steel The clip holder may be used in combination with a tool holder in different ways. 20 Please refer to the fifth figure again. The separate tool chuck 50 of the third preferred embodiment of the present invention has substantially the same components as the second preferred embodiment, except that the taper hole 52 of the tool holder 51 is different. The lower part of the hole wall is provided with two guide grooves 53 extending in the radial direction, and two spheres 56 are embedded in the relative position of the peripheral surface of the tapered portion 55 of the clamping member 54, and the spherical surface protrudes from the peripheral surface of the tapered portion 55. M253434 new type of instruction When the fixing member 57 screwed with the clamping member 54 is driven, the clamping member 54 is restrained by the two spheres 56 falling into the opposite guide groove 53, which will cause the clamping member 54 to move upward stably. In addition, as shown in the sixth figure, the fifth part of the fourth preferred embodiment of the present invention is a five-piece tool chuck 60, the main components of which are substantially the same as those of the first preferred embodiment 10, and are characterized by: The sleeve portion 62 is located at the bottom end of the cone portion 63, and the shape is extended from the body portion of the cone portion 63. The cutter is fixed in the through hole 64 that penetrates the cone portion 63 and the sleeve portion 62.
