The invention relates to a drive apparatus (10) for the linear movement of a processing tool with respect to a workpiece, having a tool holder (18) which is fixed on a carriage (16) and is intended for the fastening of the processing tool, having a stationary guide device (12) in which the carriage (16) is guided such that it can be displaced in a vertically linear manner, and having a drive device (42) with a first force transmission means (46) which, in an engaged position, engages with a second force transmission means (40) connected to the carriage (16) in order to move the carriage (16). According to the invention, it is provided that the drive device (42) is mounted in the guide device (12) such that it can be moved between a release position, in which the force transmission means (40, 46) do not engage with one another, and the engaged position in such a way that the gravitational force of the drive device (42) causes a movement from the release position into the engaged position.
Drive apparatus for linear movement of a processing tool with regard to a work piece, having a tool holder (18) fixed in place on a carriage (16), for attaching the processing tool, having a guide device (12) that is fixed in place, in which device the carriage (16) is guided vertically in linearly displaceable manner, and having a drive device (42) that has a first force transfer means (46) that stands in engagement with a second force transfer means (40) connected with the carriage (16), in an engagement position for movement of the carriage (16), wherein the drive device (42) is mounted in the guide device (12) so that it can move between a release position, in which the force transfer means (40, 46) are not in engagement with one another, and the engagement position, in such a way that the gravitational force of the drive device (42) brings about a movement from the release position into the engagement position.
Drive apparatus for linear movement of a processing tool with regard to a work piece, having a tool holder (18) fixed in place on a carriage (16), for attaching the processing tool, wherein the carriage (16) has two guide rails (20, 22) that run parallel and at a distance from one another, and having a guide device (12) that is fixed in place, in which device the carriage (16) is guided vertically in linearly displaceable manner, with its guide rails (20, 22), wherein the guide device (12) has a fixed bearing, which is fixed in place, having at least one fixed bearing element (24), against which a first one of the guide rails (20) makes contact, as well as a floating bearing having at least one floating bearing element (28), disposed at a distance from the fixed bearing, against which the second guide rail (22) makes contact, and which can be moved away, counter to a reset force, from the at least one fixed bearing element (24).
