German hauser workpiece fixtures, hauser models, hauser prices

hauser 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. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece during any step 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 of the tool and workpiece or guide the tool direction), indexing devices (enabling 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, with machine tool fixtures being the most common, often referred to simply as fixtures. When machining a workpiece on a machine tool, to ensure the surface meets technical requirements such as dimensions, geometric shape, and mutual positional accuracy with other surfaces as specified in the drawing, the workpiece must be properly located (positioning) and securely held (clamping) before machining.

hauser Workpiece 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. Depending on the machine tool used, fixtures can be classified 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 used, they can be classified into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, and vacuum fixtures. Specialized classifications include general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, 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 different machining operations.

hauser Workpiece Fixture Operation

1) Assemble the two engine bushings 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 spiral clamp; simultaneously position the two 4 engine bushings with pins, and clamp them with quick-release spiral clamping devices; 2) After tack welding, release the quick-release spiral clamping devices, pull out the pins, remove for welding; 3) Place the welded assembly back on the fixture body, position the welded assembly using stop pins and stop plates, clamp the welded assembly with a spiral clamp; then place the assembly of the M6 nut and horn bracket onto the welded assembly, position it using the conical pin on the spiral clamping mechanism and the groove in the pressure plate of the spiral clamping mechanism, and clamp it with the spiral clamping mechanism; 4) Perform three-sided welding on the assembly of the M6 nut and horn bracket and the strut, then release all spiral clamps, the pressure plate of the spiral clamping mechanism clamping the M6 nut and horn bracket assembly is lifted by springs, the positioning conical pin on it disengages from the welded assembly, then push out the pressure plate so that one end disengages from the stud of the spiral clamping mechanism, rotate the pressure plate to one side of the welded assembly, then remove the welded assembly.

hauser Workpiece Fixture Applications

1) Consistently ensure workpiece machining accuracy: When clamping a workpiece with a fixture, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, ensuring consistent machining accuracy for a batch of workpieces. 2) Reduce auxiliary time and improve labor productivity: Using fixtures makes workpiece clamping convenient and fast, eliminating the need for layout and alignment, significantly reducing auxiliary time; clamping the workpiece in a fixture increases its rigidity, allowing for higher cutting volumes; fixtures capable of clamping multiple workpieces or at multiple stations can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Expand the range of machine tool applications and achieve multi-functionality: By attaching different types of fixtures according to the forming motion of the machining machine tool, the original process range of the machine tool can be expanded. For example, installing a boring template on the carriage of a lathe or the table of a radial drilling machine allows for boring operations on box-type parts. 4) Ensure machining accuracy: Using fixtures for installation accurately determines the mutual positions between the workpiece, machine tool, and tool. The positional accuracy of the workpiece is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Increase productivity and reduce costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces with fixtures increases workpiece rigidity, allowing for higher cutting volumes; multi-workpiece and multi-station fixtures can be used, and high-efficiency clamping mechanisms can be adopted, all of which contribute to improved labor productivity. Additionally, using fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of lower-skilled workers, and significantly lowers production costs. 6) Expand the process range of machine tools: Using special-purpose fixtures can change the original purpose of the machine tool and expand its application range, achieving multi-functionality. For example, after installing boring template fixtures on a lathe or radial drilling machine, boring operations can be performed on hole systems of box parts; special-purpose fixtures can also convert a lathe into a broaching machine, fully leveraging the capabilities of general-purpose machine tools. 7) Reduce worker labor intensity: Clamping workpieces with fixtures is convenient and fast. When using pneumatic, hydraulic, or other clamping devices, worker labor intensity can be reduced.
