New description: [New technical field] This creation department is about the improvement of a milling cutter structure, especially an improved and innovative design of a milling cutter structure that is easy to assemble, increases work efficiency and reduces tool damage cost. [Prior Art] According to the conventional milling cutter, as shown in the fourth figure, it is mainly integrally formed as a gear cutter (92) having a shank (91), and the outer edge of the gear cutter (92) is provided. A plurality of outwardly projecting tooth hooks (921) are formed by welding a blade (93) made of tungsten steel to the same side of each tooth hook (921). Although the above-mentioned milling cutter structure also has the function of milling cutter processing, in the actual implementation, it has found the following shortcomings, and it is urgent to be improved: 1. The above-mentioned milling cutter structure, due to the blade system made of tungsten steel It is glued and fixed on each tooth hook of the gear cutter, which is not only easy to break and fall off, but also if a blade breaks and falls off, it will not be smooth when the milling cutter is processed, and the whole tool needs to be replaced, so the cost is better. high. 2. For the above-mentioned milling cutter structure, since the blade made of tungsten steel is bonded and fixed to each tooth hook of the gear cutter, it is not only easy to break and fall off, but also has a residual jam as long as the blade breaks off. A phenomenon in which the processing element is damaged within the processing element. The reason is that the creators have, in view of this, upholding the rich experience in design and development and actual production of the relevant industry for many years, researching and improving the existing structure and lack, providing a milling cutter structure improvement, with a view to completely improving the existing missing 0 5 M294377 [ The new content] is related to the improvement of the structure of the milling cutter. It is mainly made up of a tool holder with a gear. The tool holder is made of external thread at one end, and the gear tool is made of light steel. With concave hole, concave hole ς = thread 'just tightening screw is set on the thread outside the shank, gear cutter and outside, many toothed blades' adjacent toothed blades are respectively provided with relative: one == And the other - the outer guiding surface of the oblique; according to this, by simply setting the returning tool on one end of the shank and adding the material-body molding, the tamper is not easy to break when used, and The scrap can be added by the guide surface to increase the efficiency and reduce the cost of tool damage. 〃 [Implementation] ^ 2 In order to make the technical means of this creation more complete and clear, please refer to the drawing and drawing number together, and explain in detail as follows: f First, please refer to the first to the third As shown, the improved milling cutter structure of the present invention is mainly formed by screwing a gear cutter (2) at one end of a handle (1); the handle (1) can be externally threaded with iron, steel, or other metal ends (8) The gear cutter (2) is made of two turns, and has a concave hole (21) in the center thereof, and the concave hole has an internal thread (211), and the screw can be screwed on the thread (1) of the shank (1), and the shank is tilted. (1) The rotation makes the knife, (1) and the gear cutter (2) more tight, and can drive the gear cutter (2) to rotate on the component to be processed, and the gear cutter (2) has the outer edge. A plurality of toothed blades (22), one side of the toothed blade (22) has a vertical surface (221), and the other side forms a bevel (222) at the intersection of the vertical surface (221), so that the vertical surface (221) and the vertical surface (221) The chamfered surface (222) intersects to form a sharp edge, and the outer end of the chamfered surface (222) extends toward the inner diameter to form an inclined surface M294377 (223) When the blade is processed on the component to be processed, the contact surface is smaller, and the generation of noise is reduced, and the adjacent toothed blade (22) of the gear cutter (2) is respectively on its chamfered surface (222) The chip bevel (224) extending toward the inner diameter and oppositely forming the inner side and the outer side inclined, so that the gear tool (2) is processed by the workpiece to be processed, and the scrap generated by the working piece can be used by the guide chip The inclined surface (224) is smoothly discharged on the side to make the work smoother and the processing efficiency is better. For the assembly and use, please refer to the external thread (11) of the gear cutter (2) with the internal thread (211) corresponding to the concave hole (21) of the gear cutter (2) at one end of the shank (1). On the top, the milling cutter can be assembled; in use, the shank (1) can be tightened with the gear cutter (2) due to the rotation of the shank (1), and the gear cutter can be driven (2) It is processed on the component to be processed with the rotation, and the gear cutter (2) is made of tungsten steel. It is not easy to break during use, which not only increases the work efficiency of the machining, but also reduces the damage of the tool. The cost of replacement, plus one side of the toothed blade (22) is a vertical surface (221), while the other side forms a chamfered surface (222) at the intersection of the vertical surface (221), the vertical surface (221) and the chamfered surface (221) just intersecting to form a sharp edge, and the outer end of the chamfered surface (222) extends toward the inner diameter to form an inclined surface (222), so that the cutting edge is smaller when the blade is processed on the component to be processed, and the noise is reduced. Produced, in turn, on the gear cutter (2) adjacent to its toothed blade (22) The inclined surface (222) extends in the inner diameter direction and forms a bevel inclined surface (224) which is opposite to one side and the other side is inclined outward, so that the gear cutter (2) is processed by the workpiece to be processed, and the workpiece is generated by the workpiece. The guide vane bevel (224) can be smoothly discharged on the side to make the work smoother and the processing efficiency is better. From the above, the structure and implementation of this creation can be seen that the 7 M294377 has the following advantages: 1. Since the gear tool is made of tungsten steel, it is not easy to break when used. Increase the efficiency of machining operations, and reduce the cost of tool damage that must be replaced. 2. This design is easy to assemble and replace tools by simply setting the gear cutter to one end of the holder. This increases the efficiency of the work. 3. Since the gear tool is made of tungsten steel, it is not easy to be broken during use. Therefore, there is no problem that the existing milling cutter blade is easy to break and fall and jams in the processing component to cause the machining component. Damage to the phenomenon of cockroaches. 4. This creation is due to the fact that one side of the toothed blade of the gear cutter has a vertical plane, while the other side forms a chamfered surface at the intersection of the vertical plane, and the vertical plane and the chamfered surface just intersect to form a sharp edge, and the outer end of the chamfered surface is inward The diameter extends to form an inclined surface, so that the cutting edge is smaller when the blade is processed on the component to be processed, thereby reducing noise generation. 5. This creation is because the gear cutter has its adjacent toothed inserts extending in the inner diameter direction on its chamfered surface and forming an inwardly opposite side and the other outwardly inclined chamfering surface, so that the gear cutter is processed on the component to be processed. When the scraps generated by the working pieces can be smoothly discharged by the side of the inclined surface of the guide chip, the work is smoother and the processing efficiency is better. In summary, the present embodiment can achieve the expected use efficiency, and the specific structure disclosed therein has not been seen in similar products, nor has it been disclosed before the application, and has fully complied with the provisions of the Patent Law. And the request, the application for a new type of patent in accordance with the law, please forgive the review, and grant the patent, it is really sensible. 8 M294377 [Simple description of the diagram] The first picture: the exploded view of the creation of the second picture: the front view of the creation of the third picture: the side view of the creation of the fourth picture: the existing front view of the main components symbol description] < Creation > (1) Shank (11) External thread (2) Gear cutter (21) Recessed hole (211) Internal thread (22) Toothed blade (221) Vertical surface (222) Oblique surface (223) Inclined surface ( 224) Chip Bevel <Existing> (91) Tool Holder (92) Gear Tool (921) Tooth Hook (93) Blade 9
