German guethle workpiece clamps guethle model guethle price

guethle workpiece clamps are devices that hold objects to manipulate them. They can grip 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 gripping actions: External gripping: 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 holds the object. Internal gripping: In some applications, due to the geometry of the object or the need to access the exterior of the object, it is necessary to grip the object from the center. In this case, the gripper holds the object through expansion force.

guethle workpiece clamp classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are placed on the structure of the fixtures used. According to the machine tool used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the clamping power source adopted by the fixture, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, vacuum fixtures, etc. Specialized classification includes general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a fixture used on automatic lines. This fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece, moving from one station to the next along the automatic line for processing different operations.

guethle workpiece clamp principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup collar. The flat vacuum suction cup first connects the vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe joint, and then contacts the object to be lifted, such as glass or paper. The vacuum equipment is started to create negative pressure inside the suction cup, thereby securely sucking the object to be lifted, allowing the transport of the object to begin. When the object to be lifted reaches its destination, air is steadily inflated into the vacuum suction cup, changing the internal pressure from negative to zero or slightly positive, causing the vacuum suction cup to detach from the object, thus completing the task of lifting and transporting heavy objects. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers severe wear and thus deteriorates quickly. It is a pneumatic wearable part. Precisely because of this, it stands out significantly among many pneumatic components. 2) Easy to use. Regardless of the material of the object being sucked, as long as it can seal and not leak air, it can be used. Electromagnetic chucks cannot do this; they can only be used on steel materials, and plates or objects made of other materials cannot be sucked. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and produce no light, heat, or electromagnetic effects. 4) Does not damage the workpiece. Since vacuum suction cups are made of rubber material, picking up or placing down the workpiece will not cause any damage to the workpiece. Hook-type lifting gear and steel cable lifting gear cannot do this. In some industries, where requirements for workpiece surfaces are particularly strict, only vacuum suction cups can be used.

guethle workpiece clamp selection

When selecting pneumatic grippers and jaw designs, these are the main factors to consider: 1) Part shape, orientation, and dimensional variations: If the object has two opposing flat surfaces, a two-jaw parallel gripper can be used, which resolves dimensional deviation issues. For cylindrical objects, a two-jaw gripper can also be used for holding. Note that containment or enveloping grips require less force. 2) Part weight: The gripping force must be sufficient to hold the object steady while performing the required operations on it. The type of jaw design must be considered when calculating the required gripping force. Please note that safety factors should be considered when selecting the required force, and air pressure is also a factor to note. 3) Accessibility: This relates both to the operation being performed and to the spatial size of the gripper jaws. If work needs to be performed on the exterior of the object, internal gripping is required. Scissor-style grippers are usually lower in price but require more space for jaw movement. 4) Environment: Grippers used in harsh environments or cleanrooms require corresponding designs. 5) Object retention: When air pressure is no longer supplied, the gripper will release its hold on the object, and the object will drop. For such applications, spring-assisted grippers can be used.
