Abstract
A device for drilling an acoustic component including a drilling head, and the drilling head has a support unit including at least two autonomous drilling cassettes. Each cassette includes at least one drill bit, a stationary frame with respect to the support unit, and a bit support moveable along the main axis (Δ) of the cassette between a retracted position and a deployed position. In particular, each bit support is equipped with a device for sensing the skin of the acoustic component to be drilled allowing to automatically control the drilling depth of the bits of each cassette.

A device for drilling an acoustic component comprising a drilling head, the drilling head comprising a support unit comprising at least two autonomous drilling cassettes each comprising at least one drill bit, a stationary frame with respect to the support unit and a bit support moveable along a main axis (Δ) of said at least two autonomous drilling cassettes between a retracted position and a deployed position,
- wherein each bit support is equipped with at least one device configured to sense a skin of the acoustic component to be drilled, allowing a position of the bit support to be adjusted relative to the skin of the acoustic component to be drilled before drilling of the skin begins to allow for automatic control of a drilling depth of said at least one drill bit of each autonomous drilling cassette.
A cassette cooperating with a device for drilling an acoustic component, the device comprising a drilling head, the drilling head comprising a support unit,
- the cassette comprising:
- a stationary frame with respect to the support unit of the device;
- a brushless motor;
- a bit support moveable along a main axis (Δ) of the cassette between a retracted position and a deployed position;
- means for moving the bit support in translation;
- an inertial dynamic balancing mechanism;
- at least one bit;
- and
- a sensing device mounted to the bit support for sensing a skin of the acoustic component to be drilled, allowing a position of the bit support to be adjusted relative to the acoustic component before drilling of the acoustic component begins to allow for automatic control of a drilling depth of the at least one bit.
