气动式钳制器楔形块曲线设计

The Mechanical Analysis of a New Type of Pneumatic Clamping Elements for Roller Guides

高速高精直线电机应用于机床上时,滚动直线导轨会缺乏制动功能。针对此问题,将楔形增力技术运用于直线导轨的制动系统中,设计一种新型气动式钳制器。首先分析直线导轨钳制器内部楔形块曲线,按等加速运动规律对楔形块曲线进行设计;然后,通过三维CAD软件Pro/E,对楔形块进行曲线参数化建模,精确建立了钳制器关键运动零部件的三维模型;最后,运用动力学仿真软件ADAMS,对钳制器运动状态进行仿真分析,仿真结果验证了设计的合理性。

In order to solve the problem of lacking braking capacity of linear rolling guide system when linear motor was applied in the machine tools,a new type of pneumatic clamping device was developed using force amplifier technology by wedge.The curve of wedge block of clamping elements for the linear guide was analyzed and researched at first.Then three accurate dimensional models of key components of clamping elements were established using 3DCAD software Pro/E.Finally,the kinetics states of clamping elements were simulated and analyzed by means of the dynamics simulation software ADAMS.Simulation results prove that the design is reasonable.
