Germany ero-fuehrungen workpiece clamping fixtures ero-fuehrungen model ero-fuehrungen price

ero-fuehrungen 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. 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, 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.

ero-fuehrungen workpiece clamping fixture classification

Clamp types can be classified by usage characteristics as follows: (1) Universal general-purpose fixtures. Examples include machine vises, chucks, suction cups, indexing heads, and rotary tables. They have high versatility and can adapt well to changes in machining processes and workpieces. Their structures are standardized, and their dimensions and specifications are serialized. Most have become standard accessories for machine tools. (2) Special-purpose fixtures. These are specially designed and manufactured for the clamping needs of specific product parts in specific processes. They serve a single purpose with strong specificity and are generally designed by the product manufacturer. Common types include lathe fixtures, milling fixtures, drill jigs (machine tools used to guide drills or reamers on workpieces), boring jigs (machine tools used to guide boring bars on workpieces), and pallet fixtures (movable fixtures used on automated lines for modular machine tools). (3) Adjustable fixtures. Special-purpose fixtures whose components can be replaced or adjusted. (4) Modular fixtures. Fixtures composed of standardized components of different shapes, specifications, and uses. They are suitable for new product prototyping, single-piece and small-batch production with frequent product changes, and temporary tasks. In addition to vises, chucks, indexing heads, and rotary tables, there is a more common type called tool holders. Generally speaking, when the term "tool fixture" appears, it mostly refers to tool holders.

ero-fuehrungen workpiece clamping fixture structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. According to the motion of the fingers, they can be divided into translational and rotary types. According to the mechanical clamping method, they can be divided into external clamping and internal expansion types. According to the mechanical structural characteristics, they can be classified as electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps the workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is completely released during movement, dwelling, and loading processes. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

ero-fuehrungen workpiece clamping fixture maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to fall off easily during rapid twisting. In some cases, a clamp can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air clamp is usually installed to solve this problem. When the product's surface area is too small or the product is too heavy for vacuum suction cups, clamps can also be used to solve this problem. If the product has strict appearance requirements, the clamped area must not be the outer surface. To address this, a sensor circuit can be installed. After confirming that the clamp or suction cup has securely gripped the product, the sensor sends a signal to the manipulator to proceed to the next step. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold the product or move it out of the molding area, a special cylinder capable of independent movement without relying on manipulator operation can be added to improve this situation.
