Modular Connection Interface

The Modular Connection Interface is a critical component within Modular Tooling Fixtures systems, designed to provide a precise, rigid, and reliable connection point. It serves as the standardized mating surface that allows for the quick assembly, disassembly, and reconfiguration of modular tooling setups, such as jigs, fixtures, and clamping systems, ensuring accurate alignment and positioning in manufacturing processes. This interface is engineered to maintain zero-play mating by eliminating gaps between connected modules, transferring forces effectively, and preserving positional accuracy under load. It is typically used in machinery and equipment manufacturing, where repeatable and accurate positioning is essential for quality and efficiency. The interface is available in standard sizes with connection diameters ranging from 50 to 200 mm, conforming to ISO 702-1. It supports axial loads up to 10–50 kN and radial loads up to 5–25 kN, with repeatability of ±0.005 to ±0.02 mm as per ISO 230-2. Operating temperature ranges from -20 to 80 °C in non-condensing environments, and operating pressure is 1.0–1.6 MPa per with a note that The sealing class is IP54–IP65 per IEC 60529, offering protection against dust and water jets. Materials on file include alloy steel and tool steel, with material grades such as 16MnCr5–20MnCr5 per DIN EN 10084, and surface hardness after case hardening of 58–62 HRC per ISO 18265. Weight ranges from 2.5 to 15 kg depending on size and material. These values are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier. The interface is a component, not a standalone product, and its performance depends on proper integration with the modular tooling system.

The interface typically employs a combination of mechanical features like tapered pins, dowels, or precisely machined surfaces for alignment, along with a clamping mechanism (e.g., hydraulic, pneumatic, or manual clamps, bolts, or quick-release levers) to secure the connection. It ensures zero-play mating by eliminating gaps between connected modules, transferring forces effectively, and maintaining positional accuracy under load. The design allows for rapid changeover and reconfiguration, reducing downtime and improving productivity in manufacturing processes.
