Device for drilling plates of brittle materials, particularly glass plates.

摘要

A device (7) whose function is to drill plates (2) of fragile material, in particular glass plates, and connectable to a movable machining head (1) consisting of a supporting structure (3) and a electric rotary member (4); the device (7) is characterized by having a go support structure (10); by be provided with connecting means (12) for connecting the support structure (10) to the support structure (3) of the machining head (1); by be provided with a first (18) and at least one second (19) chucks to hold the first (18a) and second (19a) piercing tool respectively, when said chuck (18) and (19) are connected to said support structure (10) to rotate about their respective axes (20) parallel and oriented in opposite directions relative to the support structure (10) so that the cutting edges of the tools (18a) and (19a ) are located on opposite sides of the support structure (10); and the mechanism for transmitting movement (22) consists of an input member (23) connectable to said rotary member (4), and is in turn characterized in that the movement is transmitted to both chucks (18) and ( 19).
