Abstract

A tool holder for robotic curing or welding torches includes a housing having a facing part, a stop plate which is at least partially disposed within the housing and has a home position in which the stop plate is disposed proximate the housing facing part. A tool connection coupled to the stop plate is provided so that movement of the tool connection causes movement of the stop plate. A piston element is axially movably mounted in the housing and biased toward the stop plate. The piston element is disposed to be contacted by the stop plate and selectively slid axially in response to movement of either the tool connection or the stop plate. A detector sensor device including a trigger is disposed on the housing to be triggered by axial movement of the piston element. A plurality of positioning elements disposed between the stop plate and the housing facing part are cooperatively configured with at least one of the stop plate and the housing facing part so that in the home position only three of the positioning elements contact both the stop plate and the housing facing part and position the stop plate relative to the housing facing part to form three home positioning element. At least one additional positioning element is adapted to position the stop plate in response to either the tool connection or the stop plate being tilted.
