Definitions
- the invention relates to a combined electric hand tool device, such as a combination hammer, for generating an at least partially rotating movement of a tool.
- Such combined electric hand tools produce both one with a drive rotating as well as striking movement, whereby between the individual operating modes, such as drilling, drill bits or chisels, with a mode selector switch, which with connected to the gearbox, can be changed manually.
- the torque is transmitted from the drive to of the tool holder holding the tool separately and also non-rotatably locked with respect to the housing of the electric hand tool and usually more allowed as a discrete relative angular position.
- the axially displaceable switching sleeve is non-rotatable with the one with the Tool holder connected, guide tube connected and as part of the gearbox assigned by axial displacement in at least two different engagement positions Gears can be moved, one for locking the rotary movement of the tool holder serving teeth is rotatably connected to the housing.
- EP0759342A2 there is an associated positioning of a rotatable mode selector switch by an axial displacement of a resiliently biased, with the housing non-rotatably connected, locking sleeve with a radially circumferential toothing with connected to the tool holder and with assigned radially circumferential counter teeth trained guide tube lockable against the housing.
- the guide tube is connected to the tool holder Provide non-rotatable, axially displaceable switching sleeve with circumferential radial openings, into which with the assigned positioning of a rotatable mode selector switch a bolt engaging radially from the outside, non-rotatably connected to the housing Locking of the rotary movement of the tool holder with respect to the housing takes place.
- the object of the invention is to implement a further locking of the Rotary movement of the tool holder with respect to the housing of a combined Electric power tool.
- a tool holder that can be rotated at least partially about an axis of rotation a combined electrical hand tool device with several operating modes outer sleeve coaxially assigned non-rotatably, which at least one, advantageously several over radial openings distributed around the circumference, which do not necessarily have to be continuous, has in which a via a manually operated mode selector switch across Rotation axis displaceable and non-rotatable with a housing of the electrical hand tool device connected bolt, which with a sliding sleeve arranged on a drive shaft is connected, engages radially in at least one operating mode.
- a switch plate that can be manually adjusted via the mode selector switch is also advantageous into the sliding sleeve.
- the tool holder is thus over the sleeve and over the bolt engaging in the openings of the sleeve rotatably with the housing of the Electric hand tool device connected or locked against this.
- the sleeve around a guide tube with a flying piston for producing a is advantageous Impact movement arranged around.
- the sleeve is further advantageously provided on one end face with a conical pinion, which is at least partially in engagement with an associated conical drive pinion stands for the rotary drive, the drive shaft advantageously transverse to the axis of rotation of the tool holder is oriented.
- the sleeve is advantageously non-positively connected to the guide tube via its other end face connected, with an axially biased compression spring against an axially limited Movable clutch disc, positively connected to the guide tube in a rotationally fixed manner a safety clutch to limit what is transferred to the tool holder Torque is formed.
- a tool spindle 1 that is at least partially rotatable about an axis of rotation A. for fastening a tool holder, not shown, of a part shown only combined electrical hand tool device with several operating modes an outer Sleeve 2 coaxially assigned non-rotatably, which several, distributed over the circumference, radial Has openings 3, in which, via a manually operated mode selector switch 4, Transversely to the axis of rotation A and rotatable with a housing 5 of the electric hand tool device connected bolt 6 engages radially.
- the sleeve 2 is around a guide tube 7 with an internal flying piston, not shown, arranged around and on one End face provided with a conical pinion 8, which is at least partially in engagement stands with an associated conical drive pinion 9, the drive shaft B is oriented perpendicular to the axis of rotation A.
- the sleeve is one with respect to its other end face Coupled clutch plate 10 adjacent, which with the guide tube 7 form-fitting rotatably connected and axially pressed against the sleeve 2 via a compression spring 11.
- the Bolt 6 which can be displaced perpendicularly to the axis of rotation A, has a pin 6 on the shaft of the drive pinion 9 arranged sliding sleeve 12 connected, which form-fitting via a Sliding sleeve 12 engaging switching plate 13 with the manually operated mode selector switch 4 is connected.
