ns, as well as fluid bodies such as plastic clamping。 Machining fixture is an indispensable ponent in the machine tool technology to highspeed, high efficiency, precision, plex, intelligent, environmentallyfriendly direction, driven by technology is moving fixture highprecision, highperformance, modular, mix, general economic direction. First, highprecision Machining with improved accuracy, in order to reduce the positioning error and improve machining accuracy of the fixture manufacturing precision demanding highprecision positioning jig Distance accuracy up to 177。 5μm the bearing surface of the vertical fixture achieve / 300mm up to ~5μm. Precision machine tool fixture to the micron level has been raised the worlds leading manufacturer of fixture is precision machinery manufacturing enterprises. It is true that, in order to meet the needs of different industries and economy, folders with different models, as well as the different grades for the accuracy of the standard options. Second, efficient tool To improve production efficiency, doublesided, four and more than clamping fixture of more and more products. Work piece in order to reduce the installation time, all kinds of autocentering clamping, precision flat clamp, clamping levers, cam clamp, such as pneumatic and hydraulic clamping, rapid clamping new features constantly. New type of electronically controlled permanent magnet fixture, step up and release the work piece only 1~2 seconds, simplifying the fixture structure for the machine to carry out stage, faceted and processing to create the condition. American JERGENS the pany39。s ball lock clamping system,1 minutes, will be able to locate and lock fixture in the machine tool table, the ball lock clamping system of flexible production line for the replacement of fixtures, played reduce downtime and increase the role of productivity. Third, modules Modular ponents of modular fixture is the basis of the realization of portfolio. Take advantage of the modular design of serialization, standardization fixture elements, quickly assembled into a variety of fixtures, has bee a fixture technology development basis labor, time, materials, energysaving, being reflected in a variety of advanced fixture system innovation. The modular design laid the foundation for the the fixture puteraided design and assembly. Application of CAD technology to create a ponent library the typical fixture library, standard and user archive fixture optimization design, assembly fixtures for users dimensional solid. Cutting process simulation tool, both to provide users with the correct fixtures and ponents supporting the program, but also the accumulation of experience, understand the market demand, and continue to improve and perfect the fixture system. Fourth, GM Economic fixture versatility direct impact on the economy. Modules, modular fixture system, a onetime investment is relatively large, the only fixture system reconfigurable and scalability features a wide range of applications, mon good, fixture utilization, faster recovery of investment to reflect the economic good.共 5 頁 第 10 頁
