STAUFF fixtures, German STAUFF models, STAUFF prices

STAUFF fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grasp products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grasping products with rough surfaces, and polyurethane suction cups are highly durable. Additionally, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing them. Typically, to avoid scratching the surface of the product, it is best to choose bellows-type suction cups made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

STAUFF fixture applications

Whether it is a simple hydraulic fixture or a complex integrated production line, the design process for hydraulic fixtures is the same, proceeding sequentially through: formulation of the overall scheme, selection of hydraulic cylinder type 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, while swing clamp cylinders and lever cylinders provide clamping force on the product, and support cylinders prevent deformation during product machining. From simple fixturing to robot-assisted machining centers, cylinders provide clamping and support forces to improve production efficiency.

STAUFF fixture features

1) Standardization: The standardization and generalization of machine tool fixtures are two interrelated aspects. China already has national standards for fixture parts and components: GB/T2148~T2259－91, as well as standards for various general-purpose fixtures and modular fixtures. The standardization of machine tool fixtures facilitates commercialized production of fixtures, helps shorten the production preparation cycle, and reduces total production costs. 2) Precision: As the precision of mechanical products continues to improve, the precision requirements for fixtures inevitably increase accordingly. There are many structural types of precision fixtures, such as multi-tooth discs for precise indexing, with an indexing accuracy of ±0.1"; and high-precision three-jaw self-centering chucks for precision turning, with a centering accuracy of 5μm. 3) High efficiency: High-efficiency fixtures are mainly used to reduce the basic time and auxiliary time of workpiece machining, thereby improving labor productivity and reducing workers' labor intensity. Common high-efficiency fixtures include automated fixtures, high-speed fixtures, and fixtures with clamping force devices. For example, using an electric vise to clamp workpieces on a milling machine can improve efficiency by approximately 5 times; using a high-speed three-jaw self-centering chuck on a lathe ensures that the jaws can still firmly clamp the workpiece at a test speed of 9000r/min, thereby significantly increasing the cutting speed. In addition to configuring corresponding high-efficiency and automated fixtures on production lines and automatic lines, various fixtures for automatic workpiece loading and automatic fixture changing devices have appeared on CNC machine tools, especially on machining centers, fully leveraging the efficiency of CNC machine tools. 4) Flexibility: The flexibility of machine tool fixtures is similar to that of machine tools; it refers to the ability of machine tool fixtures to adapt to variable process factors through adjustment, combination, and other methods. The main variable process factors include: operation characteristics, production batch size, and the shape and dimensions of the workpiece. New types of fixtures with flexibility characteristics mainly include: modular fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and CNC fixtures. To meet the needs of modern mechanical industry for multi-variety, small-to-medium batch production, expanding the degree of flexibility of fixtures, changing the non-detachable structure of special-purpose fixtures to a detachable structure, and developing adjustable fixture structures will be the main direction of current fixture development.

STAUFF fixture selection

When selecting pneumatic grippers and jaw designs, these are the main factors to consider: 1) Part shape, orientation, and dimensional variations: If the object has two opposing flat surfaces, a parallel two-jaw gripper can be used, which resolves dimensional deviation issues. For cylindrical objects, a two-jaw gripper can also be used for clamping. Note that containment or enveloping gripping requires less force. 2) Part weight: The clamping force must be sufficient to hold the object securely while performing the required operations on it. When calculating the required clamping force, the type of jaw design must be considered. Please note that safety factors should be taken into account when selecting the required force, and air pressure is also a factor to consider. 3) Accessibility: This relates both to the operation being performed and to the spatial constraints of the gripper jaws. If external operations are to be performed on the object, internal clamping is required. Scissor-style grippers are typically lower in cost but require more space for jaw movement. 4) Environment: Grippers used in harsh environments or cleanrooms require appropriate designs. 5) Object retention: When air pressure is no longer supplied, the gripper will release its hold on the object, causing it to drop. For such applications, spring-assisted grippers can be used.
