- the invention also relates to a portable machining device intended for the carpentry trades.
- machining devices for performing machining of a part such as a wooden part. It is known to use manual machining devices each equipped with a specific tool, such as a saw, a plane, etc. which are directly manipulated by an operator to machine the piece of wood. Numerically controlled machining devices are also used and each comprise a chassis which rests on the ground of the machining place, a cutting tool or machining tool mounted on the chassis, means for automatically driving the cutting tool and means for receiving the wooden part to be machined.
- the applicant has already proposed, in particular in his patent FR3050135 and his application FR2000758, a machine tool which forms a new family of machining devices.
- the proposed machine tool is a portable device for automated machining of a wooden part.
- Such a device comprises a casing which is fixed directly to the wooden part to be machined and a numerically controlled machining head housed in the casing.
- the drawback common to all these devices is the production of shavings and dust in the form of wood particles around the working space of the operator during the machining of a part such as a wooden part.
- the shavings and wood dust produced are dispersed on the floor of the machining place in the operator's workshop.
- chips on the floor pose a risk to the operator who could slip and fall on the floor.
- shavings and dust can enter the casing of the machining device and cause damage by damaging the various elements forming the machining device.
- the applicant sought to improve the machining device and in particular the portable machining device, in order to manage the shavings and dust generated during the machining of a part.
- the invention thus aims to provide a device for machining a part, in particular a wooden part, which makes it possible to avoid damaging the constituent elements of the device by the shavings and dust produced during the machining of the room.
- the invention also aims to provide, in at least one embodiment, a device for machining a part which also makes it possible to cool the actuator of the tool for machining the device.
- the invention also aims to provide, in at least one embodiment, a machining device which facilitates the collection of chips produced during the machining of a part.
- the invention aims in particular to provide, in at least one embodiment, a machining device which makes it possible to avoid the accumulation of chips on the ground of the machining place.
- the invention also aims to provide, in at least one embodiment, a machining device which makes it possible to improve the safety of the operator who handles such a machining device.
- the invention relates to a device for machining a workpiece comprising a casing delimiting an enclosure, at least one machining head carrying a machining tool housed in said casing, and means for moving said machining tool along at least one Y axis.
- the machining device according to the invention is characterized in that it further comprises an air system for evacuating the chips produced during the machining of said part, said air system comprising:

This also makes it possible to avoid blocking the machining head by ensuring that no machining chips get stuck in the means of movement of the machining head.
- the means for circulating an air flow may for example be a dedicated ventilation system allowing the circulation of an air flow in the air circulation channel.
- the enclosure of the casing is sealed so that the air entering via said inlet can only exit via said outlet after having circulated in the circulation channel. Consequently, the flow of air expelled from said enclosure by said air passage opening forms an air curtain which prevents the introduction of chips produced by machining into the enclosure of the housing.
- said machining device is portable, in particular manuportable, that is to say that it can be carried by hand by an operator as described in the patent application FR2000758 filed in the name of the applicant.

- the circulation of air through the air passage section S is therefore partially hindered by the flaps so as to reduce this passage section of the air flow with the aim of increasing the speed of the air flow.
- a Venturi effect is thus generated.
- the air flow is forced to take the air passage section SI delimited by the shutters, which is narrower than the air passage section S, which leads to the acceleration of the air flow constituting the Venturi effect.

- These return means are configured to allow the movement of the flaps simultaneously with the movement of the machining tool, which causes the movement of said air flow passage section SI during movement of the machining tool according to the Y axis.
- each flap and the means of displacement can be direct or indirect, for example a flap is linked directly to the means of displacement, or indirectly by being linked to another element which moves when the means of displacement move, the other element being for example another pane.

- said section SI is kept regular when said machining tool is moved by the moving means.
- the surface of the passage section S 1 represents one third of the surface of the passage section S when the shutter shutters are moved . This regularity of the SI section makes it possible to ensure the acceleration of the air flow whatever the position of the machining tool.
- the return means mechanically connected to the displacement means are configured to control the displacement of the shutter flaps during the simultaneous displacement of the machining tool.
- Said means for moving the machining tool correspond to the means for moving the machining head carrying the machining tool.
