German schmitt neumann workpiece fixtures schmitt neumann models schmitt neumann prices

schmitt neumann 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 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 batches. 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.

schmitt neumann workpiece fixture applications

Whether it is a simple hydraulic fixture or a complex integrated production line, the design process for hydraulic fixtures is the same: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical parts, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yunpower cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide good positioning; swing cylinders and lever cylinders provide clamping force on the product; support cylinders prevent deformation of the product during machining. From simple fixation to robot-assisted machining centers, cylinders provide clamping and support forces to improve production efficiency.

schmitt neumann workpiece fixture technology

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 materials 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 force, 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 not less than 14 kg/cm². According to usage, they can be divided into electromagnetic chucks for grinders, electromagnetic chucks for milling and planing machines, electromagnetic chucks for tool grinders, etc.

schmitt neumann 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 assembly between the table and 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, guide rails can be used to connect them. 2) Support components: including U type angle cubes, L type angle cubes, support angle irons, angular connecting 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 position support components on the platform to ensure the workpiece meets certain height requirements during machining, primarily used for support at different heights. 3) Positioning components: including positioning squares, positioning straight edges, surface 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 machining; 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 components 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 swivel sleeves, 45 degree clamping swivel sleeves, parallel clamping swivel sleeves, vertical clamping swivel sleeves, standard support legs, swivel caster support legs with brakes, fixed support legs, frame-structure support bases, hydraulic lift support bases, support rails; Purpose: components acting on the connection or support between components 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 guard plates, tool trolleys; Purpose: auxiliary components for assembling tooling components. 9) Assembly tools: including hex keys, oil stones, magnetic pliers, and other assembly tools.
