German zuern workpiece fixture zuern model zuern price

zuern workpiece fixtures are one type of vacuum equipment actuator. 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. 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 product surface, it is best to choose a suction cup 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.

zuern workpiece fixture requirements

Whether clamping or adsorption type, the robot's end effector must also have the repeatability 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 simpler structures, 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 changed. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation issues. For cylindrical objects, a double-jaw gripper can also be used for clamping. It should be noted that retaining or enclosing clamping requires less force.

zuern workpiece fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup holder. First, connect the flat vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe fitting. Then, bring it into contact with the object to be lifted, such as glass or paper. Start the vacuum equipment to create negative pressure inside the suction cup, securing the object for transport. When the object reaches its destination, gently introduce air into the suction cup to change the internal pressure from negative to zero or slightly positive, allowing the suction cup to release the object and complete the lifting and transporting task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it experiences severe wear and rapid deterioration. It is a pneumatic wearable part. This is why 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 without leaking, it can be used. Electromagnetic chucks cannot do this; they only work on steel materials and cannot lift plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, causing no environmental pollution, and producing 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 will not cause any damage. Hook-type and cable-type lifting devices cannot achieve this. In some industries, where surface requirements for workpieces are particularly strict, only vacuum suction cups can be used.

zuern workpiece 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, pin, or positioning taper pin wear exceeds tolerance, it can be reassembled, shifting the worn areas, and then continued to be used. 3) After use, anti-rust oil needs to be applied. Regular long-term lubrication can maintain the life of the synchronous fixture; 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 synchronous fixture body and slide ways with an air gun or similar tool. When cleaning, remove the dust cover fixing screws and take off the dust cover, while extending the main jaws to the widest position, to easily clean chips accumulated inside the fixture. To avoid reduced clamping force due to rust, use anti-rust cutting oil. Remove the synchronous fixture every six months for a thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new ones immediately if severe. Lubricate thoroughly before assembly.
