Probe with a single contact component, automatically adjusting head of a chamfering- profiling machine with a contoured or straight shape

摘要

The head of the chamfering-profiling machine is installed on a structure (P) that has the ability to move like a cantilever on a vertical axle (G1) appropriately spaced from the head contact zone (1) with the border of the slab (L) to be worked. Offset, the head works following the border of the slab and adapts with precision to the variations even sudden changes in the profile of the slab. The probe is made up of a roller (1) installed on the end of a lever (2) attached to a vertical axle (3) supported indirectly by the structure (P) that holds the head. The lever (2) is stabilized by special devices (10 - 110) in the ready position and its possible moves to the right or left, are reported by transducers (9-109 or 9') transmitting and electric signal in proportion to the movement, directly to an elaborator (11) that controls the motor (N). This motor moves the cantilevered axle (G1) of the head, until this results as always correctly oriented in comparison to the portion of the border of the slab explored by the head. There is also a servo control (38-39-40) for programming the position of the head (1) and the working grinder (Q). The chamfering machine's size changes progressively.
