German hans bayer workpiece clamping fixtures, hans bayer models, hans bayer prices

hans bayer workpiece clamping fixture is an electromagnetic chuck that secures the workpiece being machined 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 they are continuously developing and improving. Initially, electromagnetic chucks were 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 plate-type workpieces. This is the traditional electromagnetic chuck, and its application has significant limitations. 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.

hans bayer workpiece clamping 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 and firmly grasp the object 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 must be certain force constraints and shape constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading. Additionally, it must ensure that the geometric deviation of the workpiece holding posture remains within the specified tolerance zone.

hans bayer 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 to weld or cast 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 material 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 suction, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power chucks. Standard suction chucks have a suction force of 10-12 kg/cm², while high-power electromagnetic chucks have no less than 14 kg/cm². According to their application, they can be divided into electromagnetic chucks for grinding machines, milling and planing machines, and tool grinders.

hans bayer workpiece clamping fixture selection and usage

With the continuous development of China's industry, electromagnetic chucks are being used more and more widely in industrial production. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, for cranes equipped with electromagnetic chucks, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, simply screw in T-shaped screws for lifting, and use T-shaped blocks and screws to fix it onto the workbench. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When adsorbing workpieces, as long as two adjacent magnetic poles are bridged, sufficient positioning suction force can be obtained, allowing grinding operations to proceed. By pressing buttons on the machine tool, magnetization and demagnetization of the workpiece can be achieved.
