Definitions
- the invention relates to a grinding machine with a stationary Wall part and with a rotatable about an axis of rotation Plate part, between which a gap is formed.
- a generic grinding machine is from DE 196 06 117 A1 known. Such a generic grinding machine works under centrifugal force by in the interior formed by wall and plate part both to machining workpieces and grinding material and both set in rotation by rotating the plate part be so that a polishing action by centrifugal action and relative speeds of workpieces and Abrasive material grains is caused.
- the annular gap between rotatable plate part and stationary wall part from the Top side by an elastic lining of the wall part and on the bottom by one on the turntable attached ceramic ring limited, the formation of the Plate part immediately below the one rectangular Cross section ceramic ring down and is tapered inside.
- the elastic Lining hardly wear due to its elasticity through which the abrasive material body is subject it turned out that the ceramic ring is loud Grinding bodies are subject to high wear, which is caused in particular by the fact that abrasive material body get stuck in the gap and due to their abrasive Effect the ceramic ring in the area of its inner top Grind off the edge so that after a short time a step with a depth of 3 mm to 5 mm is formed.
- the invention is therefore based on the object To further develop the grinding machine of the type mentioned at the beginning, which has a longer service life.
- the stated object is achieved with a Solved grinding machine of the type mentioned, which is characterized in that the gap from above a ceramic part and from below by an elastic part is limited.
- the invention thus makes a much higher one Tool life reaches than is the case with the prior art is. Replacing the ceramic ring is only essential after longer service life required.
- the elastic part of the plate part is preferably one Lining the same, while the ceramic part as a ceramic ring is trained.
- the Axis of the grinding machine must be directed vertically.
- a extremely preferred embodiment of the invention is characterized in that the ceramic part is directed downwards has nose-like projection, in particular the inner wall of the plate part and the wall part above and narrowing from top to bottom below the gap are essentially conical. The taper the inner wall to the vertical axis of rotation 30 ° to 45 °.
- this inclined Training not only of the plate part immediately below of the gap, but the inclusion of the inward downward Tapering already through the inner wall of the Part of the wall supports the abrasion-preventing arrangement of gap-limiting ceramic part on the upper wall part and also elastic gap limiting the gap on its underside Part of the turntable.
- Fig. 1 shows a preferred longitudinal section Embodiment of a grinding machine 1 according to the invention. This is constructed symmetrically about its axis of rotation A, see above that essentially only the right part of the vertical section is shown.
- the grinding machine according to the invention 1 has a stationary wall part 2. Below the same is one around the axis A by means of a drive shaft 3 rotatable plate part 4 is provided. Outside the plate part 4 can, but need not, this enclosing at the bottom of the wall part 2 at a distance Connect a stationary lower part 6 to the plate part 4.
- the parts mentioned essentially consist of Metal, like aluminum.
- the wall part 3 and the bottom part 4 have an elastic lining 7, 8 on the inside, preferably made of polyurethane, on.
- a ceramic ring 9 is provided, which is fixed with the wall part 2 is connected.
- the inner wall of the elastic lining 7 and thus of the wall part 2 has a tapering in the lower region Inclination to the vertical determined by the axis of rotation A. on, the angle of inclination for example in a May range from 30 ° to 45 °. This inclination essentially follows the inner wall 11 of the ceramic ring 9, the upper wall side 12 and rear wall 13 essentially perpendicular to each other and perpendicular or parallel are directed to the axis A.
- the ceramic ring instructs a nose-like projection on its lower inner side 14 down on that in its rear area over one from an edge 16a from below obliquely upwards and outside slope 16 into a horizontal or extending perpendicular to the axis of rotation
- a outer lower Wall area 17 to the outer edge 17a of the ceramic ring 9 passes.
- the slope 16 can also from the edge 16a to the edge 17a run continuously, so that the horizontal area 17 is omitted.
- the top 19 of the elastic lining 8 of the plate part 4 is essentially over the top 19 of the latter angled outward with an extension 18.
- the upper surface of the extension 18 is flat and extends parallel to the underside of the nose 14a.
- the grinding machine 1 is used by entering Workpieces such as rings or the like, and grinding material in the interior formed by the wall 2 and the plate 4 and rotation of the plate part 4 at high speed. As a result, workpieces are made using the abrasive material ground. Abrasive material gets into during operation the area of the gap S. Due to the elasticity of the elastic lining 8 are the abrasive effects relatively low on this; they are higher on the ceramic ring, especially in the area of its inner lower edge 21st
