Method for locating a precision robotic base component

摘要

A robotic base compartment has an interior locating surface. A plurality of pins extend squarely from the locating surface. The pins are located by pre-assembly machining and the extending pin surfaces are coated with a release agent. A robotic component plate, such as a gear- carrying plate, is assembled in the base compartment, with clearance slots surrounding the locating pins. After adjustably positioning the gear elements with one another by shifting the component plate, the slots are filled, for at least a portion, with a pourable hardenable material such as epoxy which is then allowed to harden. The components may thereafter be disassembled and reassembled without the loss of precision location. The assembly method obviates the need for manual drilling and reaming of pin holes at assembly and the attendant chip contamination that results therefrom.
