German optacom workholding fixtures optacom model optacom price

optacom workholding fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of workpieces through hydraulic control. They offer advantages such as high clamping force, reliable clamping, smooth operation, and ease of use. They are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling selected hydraulic components with designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at specified positions, and can reduce vibration and deformation during machining through floating supports. They can also utilize automatic control to press down and lift pressure plates, clearing the clamping position during machining. Hydraulic fixtures can withstand large cutting forces during rough machining, ensure accurate positioning during precision machining, and perform support, clamping, and quick release tasks that manual fixtures cannot accomplish.

optacom 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 and group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a type of fixture used on automated 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 automated line for processing different operations.

1) General-purpose fixtures: General-purpose fixtures refer to fixtures that have been standardized and can be used to process different workpieces within a certain range. For example, three-jaw chucks and four-jaw independent chucks on lathes, and vises, indexing heads, and rotary tables on milling machines. Such fixtures are generally produced by specialized factories and are often provided to users as machine tool accessories. Their characteristics are wide adaptability and low production efficiency, mainly suitable for single-piece and small-batch production. 2) Special-purpose fixtures: Special-purpose fixtures refer to fixtures specifically designed for a specific operation of a particular workpiece. Their characteristics are compact structure, rapid, convenient, and labor-saving operation, which can ensure higher machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture will be scrapped because it can no longer be used. It is only suitable for production with fixed products and large batches. 3) General-purpose adjustable fixtures and group fixtures: Their characteristic is that some components of the fixture can be replaced, and some devices can be adjusted to adapt to the processing of different parts. Fixtures used for group processing of similar parts are called group fixtures. Compared with group fixtures, general-purpose adjustable fixtures have less clearly defined processing objects and a wider scope of application. 4) Modular fixtures: Modular fixtures refer to fixtures assembled from a set of pre-manufactured standard components and parts according to the processing requirements of the part. Manufactured by professional manufacturers, their characteristics are flexibility, strong versatility, short manufacturing cycle, and reusable components, making them particularly suitable for trial production of new products and single-piece small-batch production. 5) Pallet fixtures: A pallet fixture is a type of fixture used on automated 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 automated line for processing different operations.

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 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, 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 support bases, 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, which are positioned on the platform to ensure the workpiece reaches a certain height requirement during processing, are mainly used for support at different heights. 3) Positioning components: Including positioning squares, positioning straight edges, planar angle squares, V type positioning components, and 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 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 for adjusting positional differences and gaps between components and the workpiece. 5) Clamping components: Including: 90° spiral clamps, horizontal spiral clamps, 45° spiral clamps, vertical push-type quick clamps, horizontal push-type quick clamps; Purpose: Components used to clamp the workpiece onto the platform or base components to ensure the workpiece does not shift 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 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 bases, hydraulic lifting 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 rings, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform protective plates, tool trolleys; Purpose: Auxiliary components supporting the assembly of tooling components. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
