German rotor workholding fixtures rotor model rotor price

rotor workholding 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 due to inability to reuse. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum 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 machining motion of the machine tool during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

rotor workholding fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly placed on the structure of the fixtures used. According to the machine tool used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the clamping power source adopted by the fixture, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, vacuum fixtures, etc. Specialized classification includes general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a fixture used on automatic lines. This fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece, moving from one station to the next along the automatic line for different operations.

rotor 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 to weld or cast 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. The electromagnetic chuck uses DC power supply and features stability, strong holding force, and low residual magnetism. Electromagnetic chucks can be classified into standard holding force chucks and high-power chucks. The holding force of standard holding force chucks is 10-12 kg/cm², and that of high-power electromagnetic chucks is not less than 14 kg/cm². According to application, they can be divided into electromagnetic chucks for grinding machines, electromagnetic chucks for milling and planing machines, electromagnetic chucks for knife grinders, etc.

rotor workholding 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 feature 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 surface and for combining the table with other modules. The dimensions of the base table can be chosen arbitrarily, and special dimensions can be custom-made. If high precision is required after combining tables, guide rails can be used to connect them. 2) Support components: including U type angle blocks, L type angle blocks, support angle irons, angular connection blocks, angle gauges, frame support bases, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. These are components such as shims, spacer plates, support plates, support blocks, and extension plates that are positioned on the platform to ensure the workpiece meets certain height requirements during processing, primarily serving as supports at different heights. 3) Positioning components: including positioning squares, positioning straight edges, plane angle squares, V type positioning components, eccentric circle stops; used to accurately adjust positioning location or height. These are components that precisely position the workpiece to ensure it meets certain dimensional accuracy requirements during processing; used to determine the relative positions between components and between components and the workpiece. 4) Adjustment components: including: height adjusters, adjustment shims; Purpose: components used to adjust positional differences and gaps between components and the workpiece. 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 prevent displacement during processing. 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 swivel sleeves, 45 degree clamping swivel sleeves, parallel clamping swivel sleeves, vertical clamping swivel sleeves, standard support legs, swivel castor support legs with brakes, fixed support legs, frame structure support bases, hydraulic lifting support bases, 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 eyes, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform protective plates, tool trolleys; Purpose: auxiliary components for the assembly of tooling elements. 9) Assembly tools: including hex keys, oil stones, magnetic pliers, and other assembly tools.
