ABSTRACT:
A drilling unit mounted on an arm of an assembly robot. In order to enable a drill bush of a nose piece, for guiding a drill, to be adjustably moved into exactly registering relation with a bore of a template laid on a workpiece, the nose piece is mounted on a first cylindrical member which is mounted on a second cylindrical member through a first compliance mechanism comprising elastic support members which constitute oblique links of a trapezoidal link mechanism having an imaginary intersection of the oblique links at a front end of the drill bush. The drill bush can therefore make a swinging motion about the intersection. The second cylindrical member is mounted on a guide plate through a second compliance mechanism which enables the second cylindrical member and hence the drill bush to adjustably move in a radial direction of a rotational shaft of the drilling unit.
