German matzat workpiece fixtures, matzat models, matzat prices

matzat 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 due to inability to reuse. 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.

matzat workpiece fixture operating principle

The most widely used grippers are pneumatic grippers; It is essentially a cylinder powered by compressed air. When air is supplied, the gripper jaws approach the object and grip it firmly, to perform other operations, and when the air direction is reversed, the gripper releases the object. Typical applications include changing the orientation of an object or moving it during pick-and-place operations. When the gripper holds the workpiece, there must be certain force constraints and form constraints, to ensure that the clamped workpiece, during movement, dwelling, and loading processes, is fully released. In addition, it must ensure that the geometric deviation of the workpiece holding posture remains within the specified tolerance zone.

matzat workpiece fixture operation

1) Assemble the two engine liners in sequence 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 screw clamp; simultaneously position the two 4 engine liners with pins, and clamp them with quick-release screw clamping devices; 2) After tack welding, release the quick-release screw clamping devices, pull out the pins, remove for welding; 3) Place the welded assembly back on the fixture body, The welded assembly is positioned by stop pins and stop plates, and clamped by screw clamps; then the nut M6 and horn bracket assembly are placed on top of the welded assembly and positioned by the tapered head pins on the screw clamping mechanism and the grooves cut into the pressure plates of the screw clamping mechanism, and clamped by the screw clamping mechanism; 4) Perform three-sided welding of the nut M6 and horn bracket assembly to the strut, then release all screw clamps, the pressure plates of the screw clamping mechanism that clamp the nut M6 and horn bracket assembly are spring-loaded upward, the positioning tapered head pins thereon disengage from the welded assembly accordingly, then push out the pressure plate so that one end disengages from the stud of the screw clamping mechanism, rotate the pressure plate to the side of the welded assembly, and then remove the welded assembly.

matzat 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 surface and for combining the table 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, guide 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 bases, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. These are components that position support elements such as shims, spacer plates, support plates, support blocks, and extension plates on the platform to ensure the workpiece meets certain height requirements during processing, 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 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 and 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, magnetic connection locking 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 rings, 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 elements. 9) Assembly tools: including hex keys, oil stones, magnetic pliers, and other assembly tools.
