Clamping device

The utility model provides a clamping device. The clamping device comprises a guide shaft; the two clamping plates are oppositely arranged at the two ends of the guide shaft and are in sliding connection with the guide shaft; and the driving assembly comprises a driving part and transmission parts connected to the two clamping plates correspondingly, the driving part is connected with the two transmission parts at the same time, and the two clamping plates are synchronously driven by the transmission parts to get close to each other or get away from each other. According to the clamping device, the structure is simple, the two clamping plates can be synchronously driven to get close to each other or get away from each other through the transmission part, the problem that the material clamping position of an opposite air cylinder clamp is unstable is solved, and the clamping stability is improved. 本实用新型提供了一种夹取装置，包括：导向轴；相对设置在导向轴两端的两个夹板，所述夹板与所述导向轴滑动连接；驱动组件，所述驱动组件包括驱动件和分别连接至两个夹板的传动件，所述驱动件同时连接两个传动件，且通过所述传动件同步带动两个夹
