German ews workholding fixtures ews model ews price

ews workholding fixtures are devices that grip objects to manipulate them. They can clamp and release objects while performing certain actions. Motion devices often mimic human movements; in the case of grippers, they mimic finger movements. The "fingers" themselves do not belong to the gripper; they are specialized custom tools for holding objects, called "jaws." Two main clamping actions: External clamping: This is the most common method for holding objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper holds the object. Internal clamping: In some applications, due to the geometry of the object or the need to access the exterior of the object, it is necessary to clamp the object from the center. In this case, the gripper holds the object through expansion force.

1) Locating elements: These contact the locating reference of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position between the workpiece and the tool and machine tool motion during machining. 2) Clamping device: Used to clamp the workpiece, keeping the workpiece in its established position in the fixture during cutting. As shown in Figure 6-1, nut 5 and open washer. 3) Tool-setting and guiding elements or devices: These elements ensure the correct position between the workpiece and the tool. Elements used to determine the correct position of the tool before machining are called tool-setting elements, such as tool-setting blocks. Elements used to determine the tool position and guide the tool during machining are called guiding elements. 4) Connecting elements: Elements that connect the fixture to the machine tool, ensuring the mutual positional relationship between the machine tool and the fixture. 5) Fixture body: A base component used to connect or fix various elements and devices on the fixture into a single unit. It connects and aligns with relevant parts of the machine tool, giving the fixture a definite position relative to the machine tool. 6) Other elements and devices: Some fixtures require indexing mechanisms according to the machining requirements of the workpiece; milling machine fixtures also require locating keys, etc. Not all of these components are indispensable for every machine tool fixture, but any fixture must have locating elements and a clamping device. They are key to ensuring the machining accuracy of the workpiece, with the aim of accurately positioning and securely clamping the workpiece.

ews workholding 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 on 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 part. 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. The suction force of standard suction chucks is 10-12 kg/cm², and that of high-power electromagnetic chucks is no 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.

ews workholding fixture selection and use

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 the load allowed to be lifted under specified working conditions, or in other words, 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. Through the machine tool buttons, magnetization and demagnetization of the workpiece can be achieved.
