Lower chuck (7) is fixing in clamp system, and upper grip (8) can move up and down along feather key (24) under the effect of external force.Lower chuck (7) and upper grip (8) coordinate, and can clamp size object within the specific limits.
Design principle of the present invention is as follows:
Connect by revolute pair between clamp system with slide mechanism, making between 2 mechanisms can opposing oscillatory; Base and slide mechanism have pair of sliding secondary, and making between 2 mechanisms can relative sliding, has installed pulling force sensor between base and slide mechanism.Like this, both can opposing oscillatory between clamp system and base, again can relative sliding, and the pulling force that clamp system grip objects bears can be measured.
The present invention has the following advantages: both can opposing oscillatory between clamp system and base, again can relative sliding, and has installed pulling force sensor between base and slide mechanism, can measure the pulling force that clamp system grip objects is born.Clamp system can also carry out the motion of other modes together with base, utilize a set of clamp system to complete multiple-task.
