【正文】 Centering clamping bodies such features are: simple structure the work trip and general good but the centering accuracy is not high mainly suitable for rough or semifinished tour of the needs of large and less demanding precision centering occasions. 2. Leveraged institutions centering clamping Threejaw selfcentering leveraged trading cards, sleeve for axial movement the circle are three fabric hook lever will rotate around the axis, the three struck the slider along the radial movement of the cards in order to promote its claws the work piece centering and clamping or release. This centering clamping rigid body, and move fast, by force multiplier, and the work 共 5 頁 第 8 頁 trip is also characterized by relatively large, but its relatively low precision centering. Generally about it is mainly used for rough work. Since the body can not selflocking lever, so that anizations rely on selflocking air pressure or other agencies. 3. Centering clamping wedge bodies Wedge mobile folder automatically centering body claw when the work piece surface within the hole and left the position in the fixture after the sixcylinder through the rod so that the left claw clip due to the role of ontology on the slope while the left claw folder to the opened outside the bulge will be centering the workpiece clamping the other hand claw shifted to right folder in the role of spring circle card folder under claw to release the work piece. Centering clamping bodies such pact structure usually ranging from precision centering ~ pared with the hole for the workpiece surface for positioning the base of the semifinishing processes. 4. Clipon springcentering clamping cylinder body This centering clamping sleeve body type monly used in the installation of the work piece. Elastic centering clamping simple structure, small size, easy to operate quickly, so a wide range of applications. Centering accuracy of its stability in ~ . In addition to the above described centering clamping bodies, are monly used diaphragm chuck body, corrugated centering clamping sets of institutions, as well as fluid bodies such as plastic clamping。 2. 外文原文應(yīng)以附件的方式置于譯文之后。 5μm the bearing surface of the vertical fixture achieve / 300mm up to Switzerland duplication EROWA Flexible fixture positioning accuracy of up to 2 ~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 共 5 頁 第 9 頁 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 mag 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。 ~35 1
