Abstract
A low cost cam controlled mechanical positioning apparatus for automatically tracing out a predetermined path of movement for the working head of a machine tool or the like is described. The apparatus comprises a set of two large diameter disc type control-drive cams secured in parallel planes on a common drive shaft rotatably supported on a base member and driven by an electric motor through suitable gearing. Respective cam followers engage cam surfaces formed on the undersides of the large diameter control-drive disc cams and are connected to respective linkages for translating movement of the cam follower to a working head to thereby move the working head in a predetermined path of movement in an x-y plane. A working head supporting boom is secured to a transport mechanism which is movably supported on wheel and track elements and mounted for movement along respective x and y axes by the respective linkages driven by the cam followers. The plane of the x-y movement of the working head is parallel to the planes of the control-drive disc cams and the control-drive disc cams are supported on the base member in a position to overlie and interleave with the linkage and transport mechanism to thereby form a compact design.
