German Weforma workholding fixtures Weforma model Weforma price

Weforma workholding fixtures are any tools with specific functions connected to the robot edge (joint). This may include robot grippers, robot tool changers, robot collision sensors, robot rotary connectors, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end-effectors are generally considered peripheral equipment of the robot, robot accessories, robot tools, and arm-end tools (EOA). Main elements: mechanism type, gripping method, gripping force, drive unit and control object characteristics, mass, shape, center of gravity position, size, dimensional tolerance, surface condition, material, strength, operating parameters, operating space environment, operating accuracy, operating speed and acceleration, clamping time.

Weforma workholding fixture applications

Whether it is a simple hydraulic clamping fixture or a complex integrated production line, the design process for hydraulic fixtures remains the same: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical components, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yun Dongli hydraulic cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements ensure accurate positioning; swing cylinders and lever cylinders provide clamping force on the workpiece; support cylinders prevent deformation during machining. From simple fixturing to robot-assisted machining centers, hydraulic cylinders provide clamping and support forces to enhance production efficiency.

Fixtures are process devices used to quickly secure workpieces during machining, maintaining the correct relative positions between the machine tool, cutting tool, and workpiece. In other words, Workholding tooling fixtures are indispensable components in mechanical machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, compounding, intelligence, and environmental protection, fixture technology is moving towards high precision, high efficiency, modularity, combination, universality, and economy. Fixtures are also known as jigs. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces in any process step 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 simply referred to as fixtures. When machining workpieces on machine tools, to ensure that the workpiece surface meets technical requirements such as dimensions, geometric shapes, and mutual positional accuracy with other surfaces as specified in the drawings, the workpiece must be properly positioned (location) and securely clamped (clamping) before machining. The application of machine tool fixtures helps ensure machining accuracy of workpieces and stabilize product quality; helps improve labor productivity and reduce costs; helps improve workers' labor conditions and ensure safe production; helps expand the process range of machine tools, achieving "multi-functionality of one machine". Fixtures typically consist of locating elements (to determine the correct position of the workpiece in 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 (to allow the workpiece to complete machining at several stations in one installation, including rotary indexing devices and linear movement indexing devices), connecting elements, and fixture bodies (fixture bases). The use of fixtures in electronics manufacturers is also very high. To improve production efficiency and product quality, tooling fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (capable of assembling fixed shapes and heights, etc.). Their actual applications in electronic manufacturing plants are very extensive; since they are non-standard custom-made, the only limit is imagination.

1) Can stably ensure the machining accuracy of workpieces: When clamping workpieces with fixtures, 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, making the machining accuracy of a batch of workpieces consistent. 2) Can reduce auxiliary time and improve labor productivity: Using fixtures to clamp workpieces is convenient and fast; workpieces do not need scribing and alignment, significantly reducing auxiliary time; after clamping in the fixture, the rigidity of the workpiece is improved, allowing increased cutting amounts; fixtures capable of clamping multiple pieces and multi-station workpieces can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Can expand the usage range of machine tools, achieving multi-functionality of one machine: According to the forming motion of the machining machine tool, attaching different types of fixtures can expand the original process range of the machine tool. For example, installing boring jigs on the carriage of a lathe or the table of a radial drilling machine allows for boring processing of box parts. 4) Ensure machining accuracy: Installation using fixtures can accurately determine the mutual position 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) Improve productivity and reduce costs: Clamping workpieces with fixtures allows rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces with fixtures improves workpiece rigidity, thus allowing increased cutting amounts; multi-piece and multi-station fixtures can be used to clamp workpieces, and high-efficiency clamping mechanisms can be adopted, all of which help improve labor productivity. Additionally, after adopting fixtures, product quality is stable, scrap rate decreases, workers with lower technical grades can be assigned, significantly reducing production costs. 6) Expand the process range of machine tools: Using special fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality of one machine. For example, after installing boring jig fixtures on lathes or radial drilling machines, boring processing of hole systems in box parts can be performed; through special fixtures, lathes can also be converted for use as broaching machines, fully leveraging the role of general-purpose machine tools. 7) Reduce workers' labor intensity: Clamping workpieces with fixtures is convenient and fast; when using pneumatic, hydraulic, and other clamping devices, workers' labor intensity can be reduced.
