Abstract

The present disclosure provides a gripper module, including a base, an adapter holder, a collet holder, and an actuator. The base is adapted for an adapter to be detachably disposed thereon. The adapter holder is able to engage and to buckle the adapter. The collet holder is able to engage and to buckle a collet which is installed in the adapter. The actuator is connected to the collet holder. The actuator can pull the collet holder and the collet to move, causing pressing and retraction of the collet by the conical surface between the collet and the adapter. Therefore, sizes of collets may apply to the gripper module with the adapter. By sheathing the adapter, replacement and size alternation of the collets are made easier, and precisions of allocations of the collet and the gripped workpiece are improved.

Dependent claims

A gripper module, adapted for an adapter and a collet to connect with, the collet being adapted for clamping a workpiece, the adapter having an axial hole, the collet being detachably inserted into the axial hole, the collect enclosing a clamping opening, the gripper module including:

a base, having a receiving room, the receiving room having an opening, the receiving room defining an axis and an opening direction, the receiving room being adapted for the adapter to detachably insert into via the opening, the axial hole expanding along the opening direction when the adapter is inserted into the receiving room;
an adapter holder, received in the receiving room, holding the adapter selectively so that the adapter is positioned in the receiving room;
a collet holder, received in the receiving room, holding the collet so that the collet is positioned in the axial hole;
an actuator, disposed on the base and connected to the collet holder, the actuator driving the collet holder to move along a direction opposite to the opening direction so as to drive the collet to move along a direction opposite to the opening direction and to fasten the collet into the clamping opening due to the axial hole.
