The Module Inner Installation Frame is a high-precision CNC machined internal structural frame designed exclusively for built-in module assembly, equipment internal layout optimization, and precision component fixing. Widely used in automated linear modules, sliding motion units, inspection equipment, robotic internal structures, and compact electromechanical devices, this module inner installation frame serves as the core internal supporting skeleton that integrates, positions, and fixes multiple internal parts.
Different from external protective frames, the inner installation frame focuses on internal space utilization, component coaxiality, assembly flatness, and overall structural stability, making it an indispensable foundational part for high-precision modular automation equipment.
All machining dimensions, flatness, verticality, and hole position accuracy of the module inner installation frame are strictly produced according to ISO 2768‑mk precision standards. Strict tolerance control effectively avoids internal assembly interference, component jitter, and position deviation, ensuring stable and consistent operation of the entire modular system during long-term cycling work.
The module inner installation frame features an integrated one-piece hollow frame structure optimized for internal assembly. The overall frame adopts a lightweight hollow design while retaining reinforced structural ribs on key stress-bearing areas. This scientific structural balance greatly reduces the overall weight of the module without sacrificing rigidity, effectively improving the dynamic response speed of moving modules and reducing equipment load energy consumption.
Module Internal Mounting Frame
The inner installation frame is pre-machined with multi-directional distributed mounting holes, positioning pin holes, avoiding grooves, and sinking platforms. These pre-processed structures allow direct installation of sliding rails, sensor brackets, transmission shafts, bearing seats, limit modules, and circuit fixing accessories without secondary drilling, cutting, or modification on-site. The inner wall surfaces are finely milled to ensure high flatness and smoothness, preventing assembly jamming and ensuring precise matching of internal moving parts.
All corners, hole edges and groove transitions are fully deburred and polished. Burr-free processing protects internal precision components from scratch damage and avoids tiny metal debris from accumulating inside the module, which could cause sliding blockage, sensor failure or abnormal mechanical noise. The standardized symmetrical frame design ensures uniform internal stress distribution, effectively preventing structural deformation after long-term vibration and high-frequency movement.
Our module inner installation frame is mainly made of high-strength 6061-T6 industrial aluminum alloy, which is the most ideal material for internal module structural parts. It provides high rigidity, excellent anti-deformation performance, lightweight characteristics, and good thermal conductivity. Compared with steel frames, aluminum alloy greatly reduces the self-weight of moving modules, improves equipment operating efficiency, and reduces motor load. At the same time, aluminum alloy has natural oxidation resistance, which can maintain stable structural performance in long-term enclosed internal environments.
For heavy-load and high-strength requirement scenarios, we support customized 7075 aluminum alloy and 45# steel materials to enhance overall structural strength and shock resistance. The whole frame is processed by 3-axis and 5-axis cnc milling precision milling, ensuring consistent flatness of the upper and lower reference surfaces, accurate hole position spacing, and precise groove symmetry. All thread holes are precisely tapped to ensure smooth bolt locking and stable fastening force without sliding teeth.
The module inner installation frame supports multiple industrial surface treatments to adapt to different working environments. Conventional black hard anodizing improves surface hardness, wear resistance and anti-corrosion performance, effectively resisting dust, moisture and slight oil pollution inside the equipment. Sandblasting treatment can eliminate tool marks and improve surface uniformity, making internal module assembly more compact and beautiful. Natural anodizing is also available for lightweight and low-wear internal structural applications.
Module Inner Installation Frame
This inner installation frame is widely applied in automation linear modules, sliding platform modules, visual detection equipment internal frames, robotic small joint modules, precision testing jigs, and automated feeding devices. It optimizes internal space layout, centralizes component installation positions, simplifies mechanical structure design, and greatly improves equipment assembly efficiency and operational stability.
We provide comprehensive non-standard customization services for all types of module inner installation frames. According to customer 2D drawings, 3D models or functional requirements, we can customize frame outline size, inner hollow range, mounting hole positions, avoidance groove shapes, rib distribution, sinking depth and limit structures. Whether for small-batch prototype research and development or large-scale mass production, we can maintain high-precision dimensional consistency and stable quality.
