Rotary sanding tool

Abstract

A rotary tool for moldings fabricated preferably from wood. The tool has a one-part or multi-part pad and at least one peripheral row of abrasive-coated sanding segments that are slipped onto pad elements affixed to the pad. A locking unit is movable in the axial direction such that at least the sanding segments of one peripheral row can be mounted on the pad elements.

1 . Rotary sanding tool for moldings fabricated preferably from wood, having a one-part or multi-part pad and having at least one peripheral row of abrasive-coated sanding segments that are slipped onto pad elements affixed to the pad, wherein a locking unit movable in the axial direction with which at least the sanding segments of one peripheral row can be mounted on the pad elements.  
     
     
         2 . Rotary sanding tool according to  claim 1 , wherein the locking unit is displaceable in the axial direction relative to the pad.  
     
     
         3 . Rotary sanding tool according to claims  1  or  2 , wherein the locking unit has a locking cage and, in the lower lateral marginal regions of the sanding segments, which regions are averted from the abrasive coatings, profilings are provided in such a way that the sanding segments are positively connected to the locking cage in the locked position.  
     
     
         4 . Rotary sanding tool according to  claim 3 , wherein on each lateral margin region of a sanding segment there are at least two projections forming the profiling and that the locking cage has webs adjoining the lateral marginal regions, which webs are provided with snap-in holes into which the projections engage.  
     
     
         5 . Rotary sanding tool according to  claim 1 , wherein each locking unit has a retaining ring on which the locking cage is mounted and the retaining ring is coupled by a rotatable adjusting nut in such a way that the locking unit executes a linear movement by turning of the adjusting nuts.  
     
     
         6 . Rotary sanding tool according to  claim 5 , wherein the adjusting nut is screwed onto a threaded stud of the hub of the rotary sanding tool.  
     
     
         7 . Rotary sanding tool according to  claim 1 , wherein the pad elements are detachably connected to the pad by mechanical connectors, preferably by a screw in each case.  
     
     
         8 . Rotary sanding tool according  claim 1 , wherein the rotary sanding tool is fashioned as a double-segment sanding wheel and there is a retaining ring movable in the axial direction on each of the mutually averted sides of the double-segment sanding wheel.  
     
     
         9 . Rotary sanding tool according to  claim 1 , wherein each sanding segment is fashioned as a molded part fabricated from a plastic and each pad element is made of an elastic material, for example sponge rubber.  
     
     
         10 . Rotary sanding tool according to  claim 1 , wherein each rotary sanding tool has an internal hub extending over the width or approximately over the entire width of the rotary sanding tool and the hub is fashioned as a centering cone or equipped with a conical centering bushing.  
     
     
         11 . Rotary sanding tool according to  claim 1 , which is fashioned as a single-segment wheel, wherein the sanding segments are designed such that there is a minimum clearance to a support plate holding a workpiece to be machined
