基于螺旋-斜楔二级增力的手动柔性夹具

摘要

介绍了一种基于螺旋-斜楔二级增力的手动柔性夹具的工作原理,并给出了相关的力学计算公式.该夹具将定位元件与夹紧元件合二为一,具有结构简单、夹紧力大、操作方便、对中性好和实用性强等特点.%A kind of flexible fixture based on spiral-wedge two-step force amplifier is introduced. The calculating formulae of output force are also given. Combining positioning components and clamping components to a whole. The fixture has many advantages, such as simple structure, big clamping force, convenient for operating, good centering and strong practicability.
