German vivaldi workpiece fixture vivaldi model vivaldi price

vivaldi workpiece fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grasp products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grasping products with rough surfaces, and polyurethane suction cups are highly durable. Additionally, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Typically, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

vivaldi 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 the object and firmly grasp it 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 the gripper holds a workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is completely released during movement, dwelling, and loading processes. Additionally, it should ensure that the geometric deviation of the workpiece's holding posture remains within the specified tolerance band.

vivaldi workpiece fixture process

The electromagnetic chuck consists of a base shell, iron core, coil, panel, and junction box. Its manufacturing process is as follows: 1) Select suitable materials for welding or casting the base shell. 2) Install the iron core on the base shell according to the type of chuck. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and fit it onto the iron core. 4) Pour asphalt or other waterproofing materials into the interior of the base shell. 5) Manufacture the panel and install it together with the base shell part. Electromagnetic chucks use DC power supply and feature stability, strong suction force, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power chucks. The suction force of standard suction chucks is 10-12 kg/cm², and that of high-power electromagnetic chucks is not less than 14 kg/cm². According to their application, they can be divided into electromagnetic chucks for grinders, electromagnetic chucks for milling and planing machines, electromagnetic chucks for tool grinders, etc.

vivaldi workpiece fixture maintenance

1) Check before use 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, they can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor precision, wear, and jamming, so correct lubrication is essential. After machining, be sure to clean the body and slide ways of the synchronous fixture 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 fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for 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.
