e-norm fixture Germany e-norm model e-norm price

e-norm fixture is an electromagnetic fixture that secures the workpiece by the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used and are continuously developing and improving. Electromagnetic chucks were initially used on grinding machines to replace clamping plates and bolts for securing workpieces to be ground. Such electromagnetic chucks are relatively simple and can only secure flat workpieces. This is the traditional electromagnetic chuck, which has significant limitations in its application. With industrial development, the demand for electromagnetic tools from enterprises has grown, and the requirements have become higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

e-norm fixture requirements

Whether clamping or suction type, the robot 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, with light weight, to reduce the load on the arm. Dedicated rather than general-purpose robot end-effectors have a simpler structure, high work efficiency, and can perform 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 address dimensional deviation issues. For cylindrical objects, a double-jaw gripper can also be used for clamping. Note that retaining or encompassing gripping requires less force.

e-norm fixture principle and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup clamp. First, connect the flat vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe joint. 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 handling task. 1) Prone to wear. Since it is generally made of rubber and directly contacts objects, it suffers from severe abrasion and wears out quickly. 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 lifted, it can be used as long as a seal is formed without air leakage. Electromagnetic chucks cannot do this; they only work on steel and cannot lift plates or objects made of other materials. 3) No pollution. Vacuum suction cups are environmentally friendly, causing no environmental pollution, and generating no light, heat, or electromagnetic interference. 4) No damage to workpieces. Since vacuum suction cups are made of rubber, picking up or placing workpieces causes no damage. Hook-type and steel cable lifting gear cannot guarantee this. In some industries with strict requirements for workpiece surface quality, only vacuum suction cups can be used.

e-norm fixture usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspect of an electromagnetic chuck is its parameters, among which the lifting capacity and working class are the primary performance parameters. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, insert T-shaped screws for lifting, and secure them to the workbench using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper plane of the chuck once to ensure parallelism between the upper and bottom surfaces. When adsorbing workpieces, sufficient positioning suction force is achieved by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Magnetization and demagnetization of the workpiece can be controlled via machine tool buttons. Clean the surface of the electromagnetic chuck before use to avoid scratches. Avoid severe impacts to prevent affecting precision. After use, clean thoroughly and apply anti-rust oil to prevent corrosion. When using an electromagnetic chuck independently, ensure a ground wire is connected to prevent electric shock from leakage.
