M255084 新型 Description of the new type: [Technical field to which the new type belongs] This creation is about a micro-actuated cutting tool of Scott's Russell linear mechanism (Scott_ Russell), especially a design that can use linear magnification to effectively enlarge its car Designer of cutting tool mechanism for the amount of displacement during the infeed [Previous technology] At present, the precision machining of various mechanical parts has been oriented to input data by professionals and cooperate with computer systems to control the amount of displacement during tool infeed to achieve High-precision machining effect, so it is applicable to related technical fields such as precision machining of the current industry, and gradually replaces the traditional machining method in which the technicians operate the work machine to control the amount of tool infeed. For example, the U.S. Announcement No. 6276787 "precisi〇np〇siti〇ner FOR A CUTTING TOOLINSERTj" shows the cutting tool structure, which is mainly embedded in the end of the cutting tool with a flexible mechanism with a piezoelectric phone, The flexible mechanism is mainly displaced in the radial direction and is designed to be perpendicular to the cutting direction of the tool. As a driving tool to control the amount of feeding displacement of the tool, the cutting tool is connected to the computer by a laser sensor. The system 'measures the displacement data of its tool' is used to provide feedback signals to the piezoelectric actuator as a function of the driving mechanism to control the tool's correction of the displacement amount. Junzuki describes the cutting tool structure in practical use. In the past, the design is to simply control the feed displacement of the tool by pressing the actuator to control the length change caused by the actuator. However, the design of controlling the feed of the tool by a piezoelectric actuator can only drive The tool produces the same amount of displacement as the piezoelectric actuator with a change in length. M255084 'does not effectively enlarge the tool's displacement when the tool is fed. Therefore, the tool itself cannot perform long-distance feed displacement control. The precision machining of various mechanical parts is not practical. [New content] Therefore, in order to improve the shortcomings of the conventional cutting tools described above, the creator has developed a "micro-actuated Siro two linear mechanism (Sc〇tp "Russel 1) cutting tool", I hope that this design can effectively enlarge the displacement of the turning tool when entering the tool ϊ 'to facilitate the use of precision machining of various mechanical parts, is its main creative purpose. In order to achieve the above-mentioned creation purpose, the technical means used in this creation is to provide two kinds of micro-actuated Shiro two linear mechanism (SeQtt_Russeii) cutting tools, which has a base that can be fixed on the working abutment.
