segenwitz grippers Germany segenwitz models segenwitz prices

segenwitz grippers are devices that hold objects for manipulation. They can clamp and release objects while performing certain actions. Motion devices often mimic human movements; in the case of grippers, they mimic finger movements. The "fingers" themselves are not part of the gripper; they are specialized custom tools for holding objects, called "jaws." Two main clamping actions: External clamping: This is the most common method for holding objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper will secure the object. Internal clamping: In some applications, due to the geometry of the object or the need to access the exterior of the object, it is necessary to clamp the object from the center. In this case, the gripper holds the object through expansion force.

segenwitz gripper operating principle

The most widely used grippers are pneumatic grippers; they are essentially cylinders powered by compressed air. When air is supplied, the gripper jaws approach the object and grip it firmly to perform other operations, and when the air direction is reversed, the gripper releases the object. Typical applications include changing the orientation of an object or moving it during pick-and-place operations. When a gripper holds a workpiece, there must be certain force constraints and form constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading. Additionally, it must ensure that the geometric deviation of the reproduced workpiece clamping posture remains within the specified tolerance zone.

segenwitz gripper structure

Mechanical gripping end-effectors used in loading and unloading industrial robots are mostly two-finger claw types. Classified by finger motion, they can be divided into translational and rotary types. Classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. Classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as combinations thereof. When the end-effector holds a workpiece, there must be certain force constraints and form constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading. Additionally, it must ensure that the geometric deviation of the reproduced workpiece clamping posture remains within the specified tolerance zone.

segenwitz gripper maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pins are worn beyond tolerance, they can be ground and repaired; if the baffles, pins, or locating tapered pins are worn beyond tolerance, they can be reassembled, offsetting the worn areas for continued use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the life of synchronous grippers; incorrect lubrication leads to reduced clamping force, poor accuracy, wear, and seizing, so proper lubrication is essential. After machining, be sure to clean the synchronous gripper body and slide surfaces with an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while opening the main jaws to their widest position to easily clean chips accumulated inside the gripper. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous gripper every six months for thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new items immediately if severe. Lubricate thoroughly before assembly.
