eul werkzeuge workpiece fixtures are devices used in the manufacturing process to secure the workpiece in the correct position for machining or inspection, also known as jigs. In a broad sense, any device used to quickly, conveniently, and safely install workpieces during any stage of the process can be called a fixture. Fixtures typically consist of locating elements (to determine the correct position of the workpiece within the fixture), clamping devices, tool-setting guide elements (to determine the relative position between the tool and the workpiece or to guide the tool direction), indexing devices (allowing the workpiece to undergo machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and fixture bodies (fixture bases). Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures, among which machine tool fixtures are the most common and are often simply referred to as fixtures. When machining workpieces on machine tools, to ensure that the surface of the workpiece meets the technical requirements specified in the drawings, such as dimensions, geometric shapes, and mutual positional accuracy with other surfaces, the workpiece must be properly located (positioning) and securely clamped (clamping) before machining.

Whether gripper-type or suction-type, robot end-effectors must also have the repeatability required for the task. The structure of the robot end-effector should be as simple and compact as possible, with light weight, to reduce the load on the arm. Specialized robot end-effectors have a simpler structure than general-purpose ones, offer high work efficiency, and can perform various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structures and high costs. Therefore, it is recommended to design and use serialized, standardized, specialized robot end-effectors that can be quickly replaced. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to address dimensional deviations. For cylindrical objects, double-jaw grippers can also be used for clamping. Note that retaining or encompassing gripping requires less force.

Workpiece varieties for small-batch, multi-variety production already account for approximately 85% of the total number of workpiece types. Modern production requires enterprises to frequently update their product varieties to adapt to market demands and competition. However, most enterprises are still accustomed to extensively using traditional special-purpose fixtures. In factories with medium production capacity, there are typically thousands to nearly ten thousand sets of special-purpose fixtures. On the other hand, in enterprises with multi-variety production, approximately 50~80% of special-purpose fixtures need to be updated every 3~4 years, while the actual wear of the fixtures is only about 10~20%. To meet the application of new machining technologies such as CNC machine tools, machining centers, group technology, and Flexible Manufacturing Systems (FMS), machine tool fixtures have the following characteristics: 1) They can quickly and conveniently equip new products for production, shortening the production preparation cycle and reducing production costs; 2) They can clamp a group of workpieces with similar characteristics; 3) They are suitable for high-precision machine tool fixtures for precision machining; 4) They are suitable for new types of machine tool fixtures for various modern manufacturing technologies; 5) They adopt efficient clamping devices powered by hydraulic stations and other power sources to further reduce labor intensity and improve labor productivity; 6) They improve the standardization level of machine tool fixtures. This is mainly reflected in four aspects: standardization, precision, efficiency, and flexibility.

eul werkzeuge workpiece fixture classification

1) Base components: Such as square, rectangular, and circular base plates, used as fixture tooling tables. All five working faces of the table feature grid-marked holes. The flatness, parallelism, and perpendicularity tolerances of these five faces, 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 precision 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 seats, etc.; used for height positioning or platform expansion, as well as for positioning or clamping other accessories. These are components used to position support pieces on the platform to ensure the workpiece reaches a certain height requirement during machining, such as shims, spacer plates, support plates, support blocks, and extension plates, mainly used for support at different heights. 3) Locating components: Including locating squares, locating straight edges, planar squares, V type locating components, eccentric circle stops, used for accurately adjusting positioning positions or heights. These are components used to precisely locate the workpiece to ensure it meets certain dimensional accuracy requirements during machining; they 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 machining. 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 elements. 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 seats, hydraulic lift support seats, support rails; Purpose: Components used for connecting or supporting 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: Auxiliary components for assembling tooling elements. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
