Desktop Robotic Arm Rotational Joint Housing

A disc-shaped metal structure featuring a central bearing cavity and motor mounting flange, specifically designed for desktop-level robotic arm rotational joints. The body exhibits distinct machining textures; the left square block secures the drive unit, while the right circular end cap includes multiple bolt holes for connecting subsequent links. The overall design meets transmission support requirements within compact spaces.

The core of this non-standard part lies in controlling the coaxiality between the inner bore and outer diameter, as well as the flatness tolerance of mounting surfaces, to ensure smooth, jam-free rotation after assembly. For positioning pin holes on the side walls and threaded holes on the end faces, a unified datum must be maintained during multi-step clamping to prevent positional deviations from affecting final assembly precision.

Equipped with vertical machining centers and coordinate measuring machines (CMM), our factory performs precision milling and inspection of key mating dimensions according to drawings. Adhering to the ISO 9001 quality system, we handle the entire manufacturing process from raw material selection and rough/fine machining to surface treatment. Quotations require clear specification of material grades (e.g., aluminum alloy or stainless steel), specific tolerance bands, and surface finish standards.
