Definitions
- the invention relates to a drill stand for a portable core drilling machine.
- a drill stand for a portable core drilling machine has one Footplate on.
- the base plate has an elongated hole Fastening with a dowel bolt to the surface to be drilled and two bearing blocks for Definition of a column for the core drilling machine.
- a light base plate is made of cast metal and is on the workpiece side stiffened in a plate shape over ribs so that it only lies on the edge and Take up unevenness in the surface. Due to the high mechanical static and dynamic stress can cause fatigue and fractures in the footplate come, which limits their lifespan.
- the object of the invention is to realize a highly rigid and unbreakable drill stand for a portable core drilling machine.
- the base plate of a drill stand points to a portable one Core drill with a surface fastener and one Column fastening means at least one stiffening chamber, which in longitudinal section to the drilling axis is closed at the edge.
- base plate Due to the self-contained edge in longitudinal section to the drilling axis Stiffening chamber of the one-piece or multi-piece transverse to the drill axis Bolts or bonds that are rigidly assembled, base plate becomes one lightweight, rigid and strong sandwich structure.
- the stiffening chamber of the footplate is advantageously open at least on one side, further advantageously designed without undercuts, which means that production using the casting process such as Metal die casting is possible.
- the stiffening chamber of the footplate on two opposite sides is advantageous open design, whereby further transverse stiffening webs or Stiffening chambers can be produced symmetrically in the center.
- Feet on the workpiece plate are advantageously arranged on the workpiece side, as a result of which a stable Support on the workpiece surface and a compensation of unevenness is achieved.
- the footplate has at least two mutually transverse Stiffening chambers, whereby a high transverse bending stiffness is achieved.
- the base plate advantageously consists of a light metal alloy such as one Magnesium alloy, aluminum alloy, which is light and very pressure-resistant.
- a one-piece Base plate 2 made of a magnesium alloy, a surface fastener 3 in the form of a Elongated holes for attachment to a surface 4 serving as a workpiece with a Dowel bolts 5 and a column fastener 6 in the form of two bearing blocks for one Stand column 7 on.
- the base plate 2 In longitudinal section to the drilling axis A, along which high feed forces F and torques M act, the base plate 2 has a plurality of closed edges Stiffening chambers 8a, which are open here on two opposite sides is trained.
- the foot plate 2 has transverse to the stiffening chambers 8a Stiffening chambers 8b.
- feet 9 are arranged on the workpiece.
