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. 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.

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 rather than general-purpose robot end effectors have a simpler structure, but high work efficiency, and can complete various operations. In contrast, "universal" end effectors may have disadvantages such as complex structure and high cost. Therefore, it is recommended to design and use serialized and standardized dedicated robot end effectors that can be quickly replaced. If the object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation problems. For cylindrical objects, double-jaw grippers can also be used for clamping. It should be noted that retaining or enveloping 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 different types of chucks. 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 waterproof materials into the interior of the base housing. 5) Manufacture the faceplate and install it together with the base housing part. 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 high-power chucks. The holding force of standard holding force 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 grinding machines, electromagnetic chucks for milling and planing machines, electromagnetic chucks for tool grinders, etc.

Galdabini workpiece clamping fixture maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerance, it can be repaired by grinding; if the baffle plate, pin, or locating tapered pin wear exceeds 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 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, while extending the main jaws to the fully open position to easily clean chips accumulated inside the clamp. To avoid 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.
