Gripper Finger Change System From Schunk Reduces Setup Time

Schunk’s manual BSWS-M gripper finger system is designed to mechanically unlock the top jaw and pull away from the gripper with the push of a button. According to Schunk, attaching a new jaw and connecting it with the gripper is also just as easy.

As a result, Schunk says the toolless jaw quick-change system reduces setup times. Dowel pins and a corresponding bore holes serve as additional, optional mounting aides. This is meant to ensure that they are mounted in the correct position; for example, in the case of asymmetric finger pairs.

The toolless jaw quick-change system is available in three versions. The exchange mechanism of the BSWS-BM version (available in seven standardized sizes, from 50 to 200) is incorporated into the base, which is mounted on the base jaw of the gripper; therefore, only the gripper fingers need to be changed. For this version, existing Schunk gripper fingers, which are equipped with an adapter bolt from the BSWS-A series, can be used.

The second version, the BSWS-URM (six sizes, from 50 to 160, are available), can be modularly incorporated into customized, attachable fingers. The gripper fingers include a kit with the necessary locking mechanism for direct installation in the gripper fingers. Since there is no base, the complete finger length can be used for clamping.

The third version is the BSWS-ABRM (available in six sizes, from 50 to 160) includes finger blanks with an integrated change mechanism, which can be adapted to the respective clamping contour individually by the user.

According to Schunk, all three versions can be combined with every Schunk premium gripper and numerous gripping modules with Schunk PGN-plus finger interface.
