Hand machine tool with clamping device
A hand power tool has a disk-shaped tool, and a clamping device for clamping the tool, the clamping device including at least one flange and a clamping unit for clamping the tool to the at least one flange and passing through the tool, the clamping unit and the at least one flange being configured on a key-end-keyhole principle, so that after passing axially through one another and subsequently being rotated counter to one another, the clamping unit and the at least one flange axially fix one another at least in one axial direction.
1. A hand power tool, comprising a disk-shaped tool; and a clamping device for clamping said disk-shaped tool to said hand power tool, said clamping device including at least one flange, and clamping means passing through said tool, wherein said clamping means is provided for clamping said tool to said at least one flange, said clamping means and said at least one flange being correspondingly configured for mated engagement, wherein said clamping means and said at least one flange axially fix one another in at least one axial direction after said clamping means is inserted axially through said at least one flange and the clamping means and the at least one flange are subsequently rotated counter to one another, wherein said at least one flange is formed so as to provide at least two different clamping planes for clamping said at least one flange in a manner selected from the group consisting of interchangeably clamping, selectively clamping, and both, relative to said clamping means in a bracing position, wherein said at least one flange can be clamped against said tool in said bracing position, and wherein the clamping means is a spindle extending along a central axis with at least one radially extending clamping tab, and wherein said at least one radially extending clamping tab is clamped to at least one support tab of a counter part.
2. A hand power tool as defined in claim 1 , wherein said different clamping planes define clamping positions for further disk-shaped tools having different thicknesses than said disk-shaped tool.
3. A hand power tool as defined in claim 1 , wherein said at least one clamping flange has at least two clamping planes each located on both front and back sides of said clamping flange.
4. A hand power tool as defined in claim 1 , wherein said at least one clamping flange has support tabs, said clamping means having three clamping tabs which are associated with said support tabs of said clamping flange.
5. A hand power tool as defined in claim 4 , wherein said at least one clamping flange between said support tabs have parallel recesses which are substantially congruent to and slightly larger than said clamping tabs of said clamping means.
