German TITAN Umreifungstechnik workholding fixtures TITAN Umreifungstechnik models TITAN Umreifungstechnik prices

TITAN Umreifungstechnik 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 machine tool's machining motion during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

TITAN Umreifungstechnik workholding fixture structure

The cross-sectional shape and distribution of the magnetic poles vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for clamping larger workpieces; transverse arrangement is suitable for clamping smaller workpieces. Circular chucks are suitable for clamping ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed on the chuck surface, magnetic attraction 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 a given contact area; the point of application of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

TITAN Umreifungstechnik workholding fixture applications

A fixture is a process device used to quickly secure workpieces during machining, maintaining the correct relative positions among the machine tool, cutting tool, and workpiece. In other words, Workholding fixtures are indispensable components in mechanical machining. Driven by the development of machine tool technology toward high speed, high efficiency, precision, integration, intelligence, and environmental friendliness, fixture technology is evolving toward high precision, high efficiency, modularity, combinability, universality, and cost-effectiveness. Fixtures are also known as clamping devices. Broadly speaking, any device used to quickly, conveniently, and safely mount workpieces in any operation of a manufacturing process can be called a fixture. Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures. Among these, machine tool fixtures are the most common and are often referred to simply as fixtures. When machining workpieces on a machine tool, the workpiece must be properly located (positioning) and firmly held (clamping) before machining to ensure that its surface meets technical requirements such as dimensions, geometric shape, and mutual positional accuracy with other surfaces as specified in the drawing. The application of machine tool fixtures helps ensure machining accuracy and product quality stability; improves labor productivity and reduces costs; improves working conditions and ensures safe production; and expands the technological capabilities of machine tools, enabling "one machine, multiple uses." A fixture typically consists of locating elements (to determine the correct position of the workpiece within the fixture), clamping devices, tool-setting or guiding elements (to determine the relative position between the cutting tool and the workpiece or to guide the tool direction), indexing devices (to allow the workpiece to undergo machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and the fixture body (fixture base). Fixtures are also widely used in electronics manufacturing. To improve production efficiency and product quality, fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (achieving fixed external shapes, heights, etc.). Their applications in electronic manufacturing plants are extremely broad; since they are often custom-made non-standard items, the possibilities are virtually limitless.

TITAN Umreifungstechnik 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 and for combining the table with other modules. The dimensions of the base table can be chosen freely, and special sizes 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 square blocks, L type square blocks, support angle irons, angular connection blocks, angle gauges, frame-style 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, which are positioned on the platform to ensure the workpiece reaches a certain height requirement during machining, primarily serving as supports at different heights. 3) Positioning components: including positioning squares, positioning straight edges, planar angle squares, V type positioning components, eccentric circle stops, used for accurately adjusting positioning location or height. These are components that precisely locate 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 elements to prevent displacement 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, external hex locking pins, magnetic pins; Purpose: components used for positioning and locking between elements. 7) Assembly components: including: 90 degree clamping corner brackets, 45 degree clamping corner brackets, parallel clamping corner brackets, vertical clamping corner brackets, 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 to connect or support 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 protective plates, tool trolleys; Purpose: accessory components supporting the assembly of tooling elements. 9) Assembly tools: including hex keys, oil stones, magnetic pliers, and other assembly tools.
