German komet workpiece fixture komet model komet price

komet workpiece fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include a compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped because it can no longer be used. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

komet workpiece fixture 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 and firmly grasp the object 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 in 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. In addition, it must ensure that the geometric deviation of the workpiece holding posture remains within the specified tolerance zone.

komet workpiece fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup holder. The flat vacuum suction cup first connects the vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe fitting, 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, firmly sucking the object to be lifted, allowing the transport of the object to begin. When the object is transported to the destination, air is gently 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 deteriorates quickly. It is a pneumatic wearable part. Precisely for this reason, 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 be sealed without air leakage, 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 attracted. 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, picking up or placing down workpieces causes no damage to the workpiece. Hook-type lifting gear and cable-type lifting gear cannot do this. In some industries, where requirements for workpiece surface quality are particularly strict, only vacuum suction cups can be used.

komet workpiece fixture maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerances, it can be repaired by grinding; if the baffle, pin, or positioning taper pin wear exceeds tolerances, it can be reassembled, shifting the worn areas to continue use. 3) After use, anti-rust oil must be applied. Regular long-term lubrication maintains the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so correct lubrication is essential. After machining, be sure to clean the body of the synchronous fixture and the slide ways using an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while extending the main jaws to their widest position to easily clean chip accumulation inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for a thorough cleaning (at least every two months when machining cast iron or copper parts). Check parts for damage or wear, and replace with new parts immediately if severe. Lubricate thoroughly before assembly.
