German Galdabini workpiece clamping fixtures Galdabini model Galdabini price

Galdabini workpiece clamping fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grip 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 gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing them. Usually, to avoid scratching the surface of the product, it is best to choose bellows-type suction cups 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.

Galdabini workpiece clamping fixture requirements

Whether clamping or adsorption type, the robot's end effector must also meet the repeatability accuracy required for the operation. The structure of the robot end effector should be as simple and compact as possible, and lightweight, to reduce the load on the arm. Dedicated robot end effectors have a simpler structure than general-purpose ones, but offer high work efficiency and can perform various operations. In contrast, "universal" end effectors may have disadvantages such as complex structures and high costs. Therefore, it is recommended to design and use serialized, standardized, dedicated robot end effectors that can be quickly replaced. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation issues. For cylindrical objects, double-jaw grippers can also be used for clamping. It should be noted that retaining or enclosing clamping requires less force.

Galdabini workpiece clamping fixture process

The electromagnetic chuck consists of a base housing, iron core, coil, faceplate, and junction box. Its manufacturing process is as follows: 1) Select suitable materials for welding or casting the base housing. 2) Install the iron core onto the base housing 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 housing. 5) Manufacture the faceplate and install it together with the base housing. Electromagnetic chucks use DC power supply and feature stability, strong holding force, and low residual magnetism. Electromagnetic chucks can be classified into standard holding force chucks and heavy-duty chucks. The holding force of standard chucks is 10-12 kg/cm², while heavy-duty electromagnetic chucks are 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 knife grinding machines, etc.

Galdabini workpiece clamping fixture 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 by offsetting the worn areas for continued use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the service life of synchronous clamps; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so proper lubrication is essential. After machining, be sure to clean the body of the synchronous clamp and the slide ways using an air gun or similar tools. During cleaning, remove the dust cover fixing screws and take off the dust cover, then open the main jaws to their widest position to easily clean chips accumulated inside the clamp. To prevent reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous clamp for a thorough cleaning every six months (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.
