Crank synchronous swing type clamping device

曲柄同步摆动式夹紧装置

Abstract

The utility model provides a crank synchronous swing type clamping device. A motor drives a gear to rotate, due to the fact that a connecting plate is fixed on the gear and a transmission roller at one end of the connecting plate is inserted into a sliding groove of a press rod, when the gear rotates, the connecting plate and the press rod form a slider-crank mechanism, and therefore linear movement of the motor is converted to reciprocating swing of the press rod, and a driving chuck on the press rod can be used for clamping a workpiece. In addition, a driving belt wheel and a driven belt wheel rotate synchronously, so that a following chuck at the tail end of a driven rack and the driving chuck on the press rod synchronously clamp the workpiece, and bidirectional synchronous clamping of the workpiece is achieved.
本实用新型曲柄同步摆动式夹紧装置,通过电机带动齿轮转动,由于齿轮上固定了连板,而连板一端的传动滚子插入了压杆的滑槽内,当齿轮转动时,连板和压杆形成曲柄滑块机构,这样的设计能够把电机的直线运动转换为压杆的往复摆动,能够通过压杆上的主动夹头对工件进行夹紧。另外,由于通过主动带轮和从动带轮的设置,两者同步转动,使得从动齿条末端的随动夹头和压杆上的主动夹头能够同步夹紧工件,实现对工件的双向同步夹紧。
