Tool-Receiving Devices for Portable Machine Tools, in Particular Angle Grinders

Abstract

A tool receiving device is for a portable machine tool, in particular for an angle grinder. The tool receiving device includes at least one output unit with at least one output spindle which can be rotated, and at least one rapid clamping unit which is arranged on the output spindle and includes at least one torque transmission element that is connected to the output spindle in a rotationally fixed manner, and at least one securing element, in particular a securing element which is movably mounted in an axial direction along an output axis of the output spindle. The tool receiving device further includes at least one locking unit for preventing the output spindle from rotating, and at least one actuating unit that has at least one actuating element, in particular a movably mounted actuating element.

1 . A tool receiving device for a portable machine tool, comprising:
 at least one output unit including with at least one output spindle configured for rotation;   at least one rapid clamping unit arranged on the at least one output spindle, the at least one rapid clamping unit including (i) at least one torque transmission element connected to the at least one output spindle in a rotationally fixed manner, and (ii) at least one securing element movably mounted in an axial direction along an output axis of the at least one output spindle;   at least one locking unit configured to prevent for preventing the at least one output spindle from rotating; and   at least one actuating unit including at least one movably mounted actuating element configured to actuate the at least one locking unit as a result of a movement of the actuating element,   wherein the at least one actuating element is configured to actuate the at least one securing element, or the at least one torque transmission element as a result of a movement of the at least one actuating element.   
     
     
         2 . The tool receiving device according to  claim 1 , further comprising:
 at least one gear unit configured to convert a movement of the at least one actuating element for actuating the at least one locking unit into a movement of the at least one securing element or of the at least one torque transmission element.   
     
     
         3 . The tool receiving device according to  claim 1 , further comprising:
 at least one gear unit including at least one ramp-shaped gear element configured to convert a translational or rotational movement of the at least one actuating element into a translational movement of the at least one securing element along a direction that extends at least substantially parallel to the output axis of the at least one output spindle.   
     
     
         4 . The tool receiving device according to  claim 1 , further comprising:
 at least one gear unit comprising at least one further gear element configured to cooperate with a projection arranged on the at least one securing element configured as a circumferential collar, to effect a movement of the at least one securing element as a function of an actuation of the at least one actuating element.   
     
     
         5 . The tool receiving device according to  claim 1 , further comprising:
 at least one gear unit comprising at least one further gear element configured to move the at least one securing element as a function of an actuation of the at least one actuating element,   wherein the at least one further gear element, in at least one operational state, is arranged in a non-contacting state relative to the at least one securing element.   
     
     
         6 . The tool receiving device according to  claim 1 , wherein the at least one securing element is movable, as a function of an actuation of the at least one actuating element, along a direction of movement which is transverse to a direction of movement of the at least one locking unit along which a locking element of the locking unit is movable as a function of an actuation of the at least one actuating element. 
     
     
         7 . The tool receiving device according to  claim 1 , further comprising:
 at least one gear unit comprising at least one ramp-shaped gear element arranged on a locking element of the at least one locking unit and integrally formed with the locking element of the at least one locking unit.   
     
     
         8 . The tool receiving device according to  claim 1 , further comprising:
 at least one detent unit configured to secure which secures the at least one actuating element, the at least one rapid clamping unit, and/or the at least one locking unit in at least one actuated position.   
     
     
         9 . The tool receiving device according to  claim 1 , further comprising:
 at least one detent unit configured to secure the at least one actuating element, the at least one rapid clamping unit, and/or the at least one locking unit in at least one actuated position, and by at least one gear unit,   wherein the at least one detent unit is at least partially integrally formed with the at least one gear unit.   
     
     
         10 . The tool receiving device according to  claim 1 , further comprising:
 at least one guide unit configured to guide a movement of the at least one torque transmission element and to limit at least one maximum rotational distance of the at least one torque transmission element relative to the at least one output spindle.   
     
     
         11 . The tool receiving device according to  claim 10 , wherein:
 the at least one guide unit is configured as a slot guide, and   at least one slot element of the at least one guide unit is arranged on the at least one output spindle, fixed in place, and at least one further slot element of the at least one guide unit is arranged on the at least one torque transmission element, fixed in place.   
     
     
         12 . The tool receiving device according to  claim 10 , wherein:
 the at least one guide unit comprises at least one slot element arranged on the output spindle, fixed in place, and   the at least one slot element connected to the at least one torque transmission element for co-rotation of the at least one torque transmission element.   
     
     
         13 . The tool receiving device according to  claim 10 , wherein:
 the at least one guide unit comprises at least one further slot element having at least two guide track portions that extend transversely relative to one another, and   the at least two guide track portions include an axial guide track portion and a circumferential guide track portion.   
     
     
         14 . A portable machine tool, having at least one tool receiving device according to  claim 1 .
