Abstract
A drilling device with automatic or controlled feed speed. The drilling device includes a casing that houses a drilling spindle that is to drive a cutting tool in motion to drill a workpiece having a target surface. The spindle is tiltable inside the casing relative to the axis of the casing. The device has a self-alignment, which self-aligns the spindle relative to the target surface. The self-alignment moves the spindle into a position in which its axis is essentially perpendicular to the target surface under the effect of an application of a thrust force of the drilling device against the target surface essentially along the axis of the casing.
Claims12
A drilling device with automatic or controlled feed speed, comprising:
- a casing that houses a drilling spindle configured to drive a cutting tool in motion to drill a workpiece comprising a target surface, wherein said spindle has a longitudinal axis that is tiltable inside said casing relative to a longitudinal axis of said casing;
- means of self-alignment of said spindle relative to said target surface, said means of self-alignment being configured to move said spindle, when the longitudinal axis of the spindle is not perpendicular to said target surface, into a position in which the longitudinal axis of the spindle is perpendicular to said target surface under the effect of an application of a thrust force of said drilling device against said target surface along the longitudinal axis of said casing;
- means for driving said spindle in rotation;
- and
- means for driving said spindle in translation along its axis, said means for driving in translation comprising means permitting offset of said spindle relative to said casing.
A detachable drilling module that is configured to be fixedly and removably attached to a drilling device with automatic or controlled feed, said drilling module comprising:
- a detachable casing;
- a drilling spindle attached to the detachable casing configured to drive a cutting tool in motion to drill a workpiece comprising a target surface, wherein said spindle has a longitudinal axis that is tiltable relative to a longitudinal axis of said casing;
- and
- means of self-alignment of said spindle relative to said target surface, said means of self-alignment being configured to move said spindle, when the longitudinal axis of the spindle is not perpendicular to said target surface, into a position in which its axis is perpendicular to said target surface under the effect of an application of a thrust force of said drilling device against said target surface along the longitudinal axis of said casing.
A drilling device with automatic or controlled feed speed, comprising:
- a casing that houses a drilling spindle configured to drive a cutting tool in motion to drill a workpiece comprising a target surface, wherein said spindle has a longitudinal axis that is tiltable inside said casing relative to a longitudinal axis of said casing;
- means of self-alignment of said spindle relative to said target surface, said means of self-alignment being configured to move said spindle, when the longitudinal axis of the spindle is not perpendicular to said target surface, into a position in which the longitudinal axis of the spindle is perpendicular to said target surface under the effect of an application of a thrust force of said drilling device against said target surface along the longitudinal axis of said casing;
- means for driving said spindle in rotation;
- and
- means for driving said spindle in translation along its axis, said means for driving in translation comprising means permitting offset of said spindle relative to said casing;
- wherein said means for driving in rotation and said means for driving in translation each comprise:
- a pinion mounted so as to be mobile in rotation within said casing along the axis of said casing;
- an external driving unit rotationally linked to said pinion along a rotational axis of said pinion;
- an eccentric ring;
- an internal driving unit rotationally linked with said spindle;
- the eccentric ring being rotationally linked to said external driving unit along the rotational axis of said pinion and being mobile relative to said external driving unit along a path included in a first plane passing through the rotational axis of said pinion;
- the eccentric ring being rotationally linked to said internal driving unit along a rotational axis of said spindle and being mobile relative to said internal driving unit along a path included in a second plane passing through the rotational axis of said spindle;
- the first and second planes being not parallel.
