Abstract

A hand-held grinding machine includes a grinding device for receiving or forming a grinding means, a drive device, a drive housing, and an interface device operatively connecting the grinding device to the drive device. The interface device includes a connecting housing unit formed separately from the drive housing and the grinding device for at least partially receiving the grinding device, and a docking interface arranged on the drive housing. The connecting housing unit engages around the docking interface in a fixing plane which is perpendicular to an axis of rotation of a drive shaft of the drive device. In the fixing plane, the docking interface includes at least one axial form-fitting element for forming a form fit with the connecting housing unit parallel to the axis of rotation. A projection of the axial form-fitting element along the axis of rotation is at least substantially inside the drive housing.

Dependent claims

A hand-held grinding machine comprising:

at least one grinding device configured to receive or form a grinding apparatus;
a drive device configured to drive the grinding device;
a drive housing, which receives the drive device;
and
an interface device configured to operatively connect the grinding device to the drive device, the interface device comprising:
at least one connecting housing unit formed separately from the drive housing and the grinding device, the at least one connecting housing configured to at least partially receive the grinding device;
and
a docking interface arranged on the drive housing,
wherein the connecting housing unit engages around the docking interface in a fixing plane which is perpendicular to an axis of rotation of a drive shaft of the drive device,
wherein, in the fixing plane, the docking interface comprises at least one axial form-fitting element for forming a form fit with the connecting housing unit parallel to the axis of rotation, and
wherein a projection of the at least one axial form-fitting element along the axis of rotation is at least substantially completely inside the drive housing.
