German emuge workpiece fixtures, emuge models, emuge prices

emuge workpiece fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include a compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped because it can no longer be used. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning reference of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machine tool's machining motion during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

emuge workpiece fixture structure

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for clamping larger workpieces; horizontal arrangement of rectangular magnetic poles is suitable for clamping smaller workpieces. Circular chucks are suitable for clamping ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic flux lines are evenly distributed on the surface of the magnetic disk, the electromagnetic attraction force cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces with the same contact area; the point of action of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, there are disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency during machining.

emuge workpiece fixture operation

1) Assemble the two engine bushings onto the 1 strut according to the "Strut Welding Assembly" drawing, and place them on the fixture body, position the 1 strut using stop pins and stop plates, clamp the 1 strut with a spiral clamp; simultaneously position the two 4 engine bushings with pins, and clamp them with quick-release spiral clamping devices; 2) After tack welding, release the quick-release spiral clamping devices, pull out the pins, remove for welding; 3) Place the welded assembly back on the fixture body, position the welded assembly using stop pins and stop plates, clamp the welded assembly with a spiral clamp; then place the assembly of the M6 nut and horn bracket onto the welded assembly, position it using the conical pins on the spiral clamping mechanism and the grooves in the pressure plate of the spiral clamping mechanism, and clamp it with the spiral clamping mechanism; 4) Perform three-sided welding on the assembly of the M6 nut and horn bracket and the strut, then release all spiral clamps, the pressure plate of the spiral clamping mechanism clamping the M6 nut and horn bracket assembly is lifted by springs, the positioning conical pins on it disengage from the welded assembly, then push the pressure plate out so that one end disengages from the spiral clamping mechanism stud, rotate the pressure plate to the side of the welded assembly, then remove the welded assembly.

emuge workpiece fixture classification

1) Base components: such as square, rectangular, and circular base plates, used as fixture tooling tables. All five working surfaces of the table have grid-marked holes. The flatness, parallelism, and perpendicularity tolerances of these five surfaces, as well as the positional accuracy of the holes, are very high, ensuring sufficient accuracy for positioning on the table and for combination with other modules. The dimensions of the base table can be chosen arbitrarily, and special sizes can be custom-made. If high accuracy is required after combining tables, rails can be used to connect them. 2) Support components: including U type square boxes, L type square boxes, support angle irons, angular connection blocks, angle gauges, frame support seats, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. Components such as shims, spacer plates, support plates, support blocks, and extension plates are positioned on the platform to ensure the workpiece reaches a certain height requirement during machining, mainly serving as supports at different heights. 3) Positioning components: including positioning squares, positioning straight edges, planar squares, V type positioning components, eccentric circle stops, used for accurately adjusting positioning position or height. These are components for precise positioning of the workpiece to ensure it meets certain dimensional accuracy requirements during machining; used to determine the relative positions between components and between components and workpieces. 4) Adjustment components: including height adjusters and adjustment shims; purpose: components used for adjusting position differences and gaps between components and workpieces. 5) Clamping components: including: 90° spiral clamps, horizontal spiral clamps, 45° spiral clamps, vertical quick-action clamps, horizontal push-type quick-action clamps; purpose: components used to clamp the workpiece onto the platform or base elements to ensure the workpiece does not shift during machining. 6) Locking components: including: quick-locking pins, countersunk quick-locking pins, countersunk locking pins, handle quick-locking pins, locating pins, connection lock magnetic pins, hex socket locking pins, hex head locking pins, magnetic pins; purpose: components used for positioning and locking between components. 7) Assembly components: including: 90 degree clamping angle sleeves, 45 degree clamping angle sleeves, parallel clamping angle sleeves, vertical clamping angle sleeves, standard support legs, swivel caster support legs with brakes, fixed support legs, frame structure support seats, hydraulic lifting support seats, support rails; purpose: components acting on the connection or support between elements and other parts. 8) Other components: including: retaining rings, grounding devices, spiral clamps, pipe clamps, lifting rings, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform protection plates, tool carts; purpose: auxiliary components for assembling tooling elements. 9) Assembly tools: including hex keys, oil stones, magnetic pliers, and other assembly tools.
