Definitions

  • the invention relates to a rotary drivable machine grinding tool, consisting of a carrier body which is attachable by means of connecting elements to a machine drive and which has at least one engageable with a workpiece to be ground work surface, which is equipped with abrasive, according to the preamble of Claim 1.
  • a rotary drivable machine grinding tool consisting of a carrier body which is attachable by means of connecting elements to a machine drive and which has at least one engageable with a workpiece to be ground work surface, which is equipped with abrasive, according to the preamble of Claim 1.
  • a rotary drivable machine grinding tool consisting of a carrier body which is attachable by means of connecting elements to a machine drive and which has at least one engageable with a workpiece to be ground work surface, which is equipped with abrasive, according to the preamble of Claim 1.
  • Such a tool is out US 3,252,775 A known.
  • Abrasive tools of the type described above are known as so-called "grinding wheels". Their work surfaces are usually equipped with grinding abrasive serving as an abrasive. As a work surface, all surfaces of a disc can be used, which are moved with rotation of the disc with sufficient circumferential speed for grinding around the center of rotation of the disc. The peripheral speed is highest in the periphery of the grinding wheels, so that there surface areas are usually equipped with abrasive cloths and the so-called "work surfaces” are there.
  • the working surfaces of the grinding tools can be adjusted according to the grinding Profile to be contoured.
  • the contoured work surface is covered with abrasive cloth, which is so thin that it can be folded into the contours. Used abrasive cloth must be loosened regularly from the grinding tool and replaced with re-glued abrasive cloth.
  • the invention has for its object to provide a rotating drivable grinding tool that is universally and economically useful for any grinding workpieces, especially workpieces with profiled surface, such as turned workpieces, moldings or the like.
  • the formation of the carrier body as a disk has the advantage that the carrier body can yield resiliently at grinding forces acting transversely to the disk plane during grinding. This allows a favorable soft grinding. In addition, this property of soft grinding is further promoted by the fact that abrasive cloth is attached to the support body or the disc, which has a padded layer on its underside.
  • this padding position surrounds both the disk surfaces which are approximately radially to the center of rotation, at least in the region of the periphery of the disk, as well as the outer edge or the outer edge of the plate-shaped carrier body which is in the form of a rim, then likewise in the manner of an enclosure substantially radially acting pressure forces are cushioned by the cushion layer, so that relatively aggressive, but still without chatter marks and without that builds up excessive frictional heat, especially at the bottom of narrow and deeper profiles, even with the narrow radius of the wrapped around the edge or edge Schleifleinens of the workpieces, can be smoothed.
  • the grinding tool is advantageously relatively flat, so that it is suitable for narrow grooves and punctures, as they occur in particular with turning parts made of wood or turned parts made of metal and copper materials, to grind.
  • the grinding tool according to the invention can be used for grinding work, for which previously contoured grinding wheels were required, so that now there is a universally usable grinding tool.
  • the abrasive is a sheet, that is, it may be a portion of a tape, a sheet, an abrasive sheet or the like raw or starting element having a layer of abrasive cloth or abrasive paper of desired grain size on one side, the non-slip back, is equipped with an elastic padding layer.
  • the cushion layer is advantageously a foam with appropriate porosity and elasticity.
  • the cushion layer On the non-abrasive surface of the back, such as a grinding cloth, the cushion layer is laminated or the cushion layer with the surface of the back firmly connected, for example, characterized in that the foam is foamed directly onto the back of the abrasive cloth.
  • the padding layer has a thickness of about 1 to 5 mm, preferably 2.5 to 3 mm. Thinner cushions are easily Anlagendrückbar at high Schleifandruck, that is, they can penetrate locally, whereby the benefits of soft grinding are lost. On the other hand, thicker padding layers have the disadvantage that they stretch or stretch excessively due to centrifugal forces that occur, which can lead to undesired changes in shape and, under certain circumstances, detachment from the carrier body. A thickness of the padding layer of about 2.5 mm and an open-cell plastic foam with a compression hardness of 10 to 60 and a density of 17 to 40 kg per m 3 has proven successful.
  • the inner hole of a disc ring can serve as an approach for fasteners.
  • the hole edge of the inner hole for example, corresponding material reinforcements or thickenings have, which can be formed to record for clamping elements present as connecting elements, with which the grinding tool on or on a through the inner hole extending, or in the inner hole projecting shaft, a hollow cylinder , can tension a bush or a pin of a machine drive.
  • the approach of the carrier body is designed as a short, for example, 7 mm long sleeve, wherein the disc corresponds to an approximately radially projecting from the sleeve about 10 mm wide collar flange.
  • Sleeve with collar flange thus form the support body, which can be easily and quickly put on a shaft, a hollow cylinder, a bushing, a pin or the like rotating part of a machine drive by means of the sleeve approach and centered sufficiently accurate due to the sleeve is.
  • the design of the carrier body is made such that the disc flange corresponding to the flange, based on the length of the sleeve, sits off-center on the sleeve.
  • the thickness of the abrasive material is greater than the smallest distance between the collar flange and the respective associated end of the sleeve, neither parts of the carrier body nor connecting elements are present beyond the actual grinding surface of the abrasive material, which covers the corresponding side or surface of the collar flange.
  • the inner surface of the sleeve may be provided with radially inwardly projecting dogs which are inserted into corresponding grooves, e.g. engage the present as a hollow cylinder, bush or the like connecting elements or directly in the shaft or a pin of the machine drive and ensure a rotationally fixed seat of the grinding tool.
  • sleeve and collar flange are a one-piece plastic injection molded part.
  • Sleeve and collar flange have approximately the same wall thickness and can be produced inexpensively from plastic in high quantities by injection molding.
  • Other materials for the carrier body, such as sheets, are possible.
  • After covering the collar flange with the padded abrasive there is a cheap abrasive tool that is universally applicable to many Abrasive work can be used and after wear of the abrasive grinding layer can be easily replaced completely.
  • Worn grinding tools of the type according to the invention require no reprocessing, as is the case with profiled grinding tools, but can also be disposed of completely.
  • the grinding tools according to the invention are thus so-called "disposable parts".
  • the plastic used to form the carrier body is most particularly a glass fiber reinforced polyamide.
  • the glass fiber reinforced despite thin-walled design of the support body, the necessary strength, but allows the desired resilient properties of the collar flange itself, including the yielding of the entire disc with appropriate pressure on a workpiece to be ground.
  • a polyamide has the additional advantage that this material is soluble with formic acid, so that loosened surface areas can act as an applied adhesive. As a result, after wetting the surfaces of the collar flange with formic acid, the abrasive with its cushioning layer or alternatively provided ring body can be easily and without additional use special adhesive to connect to the carrier body.
  • the compound is particularly advantageous that it is in the padding layer to an open-cell foam acts, with which the solute material of the support body can connect particularly intense and firm, since the solute material can penetrate into the pores of the foam and provides anchoring for opposite side as soon as the solvent evaporates again and the "gluing" is dried.
  • abrasive ring body consists of a plastic foam, preferably polyurethane foam of predetermined hardness.
  • the attachment of the abrasive can be made simple in that the abrasive is present in the form of a predetermined, for sizing the carrier body or the annular body respectively matching blank.
  • Blanks can be prepared and provided to equip the carrier body or ring body with it. From plates, strips, strips or the like raw material of the abrasive, the corresponding blanks can be readily manufactured.
  • each directly attachable to the carrier body blank is a flat, substantially round stamped part with wedge-shaped edge cuts or notches. The edge notches or notches make it possible to place the blank of the abrasive in the manner of a collar wrinkle-free around the outer edge of the disc or the collar flange or on the curved working surface of the annular body.
  • a hole whose diameter is about the same, but not smaller than the outer diameter of the sleeve present as approach of the carrier body is arranged in the center of the blank.
  • the hole in the center of the blank thus does not hinder the attachment of the grinding tool to a shaft or a clamping pin of a machine drive.
  • the outer diameter of the annular body is dimensioned so that its outer peripheral surface projects beyond the outer edge of the collar flange of the carrier body by a predetermined amount and in that a region of the outer peripheral surface of the annular body facing away from the carrier body Having abrasive.
  • the annular body is made of elastic plastic foam, it forms a cushion advantageous for the grinding behavior, wherein the outer dimensions of the support body projecting portions of the annular body can further advantageously give an increased Schleifan horr, since such projecting or projecting portions of the somewhat stiffer collar flange the support body are not overly supported.
  • a region of the outer circumferential surface of an annular body remote from the carrier body can be provided with a chamfer, a groove or the like profiling be, which in turn has the Abrasivlage. Cuts with different radii and varying dimensions of the chamfers allow a cost-effective provision of diverse, universally applicable grinding tools.
  • the grinding tools can be easily and quickly connected with machine drives, since a machine drive comprises a tensioned on a drive pin of a machine hollow cylinder whose outer diameter is equal to the inner diameter of the carrier body and on the at least one consisting of carrier body with annular body grinding tool attachable and by a Festsetzorganes is fastened.
  • the hollow cylinder which can also be referred to as a sleeve, has a length which makes it possible to line up different grinding tools on the hollow cylinder.
  • the mutual alignment and assignment of the grinding tools can be made so that grinding tool combinations are formed, which correspond to the respective workpiece to be ground, in particular profiled workpiece. If the abrasives are worn and need to be replaced, the entire hollow cylinder can be removed as a unit with the attached grinding tools from the drive pin of a machine. With new grinding tools stocked hollow cylinder can be provided, so that a retooling in advantageously short assembly time is possible. Business interruptions can be kept to a minimum.
  • Each clamping ring has at least one clamping screw, so that it can be fixed in any pushed-on position on the hollow cylinder.
  • grinding tools that can be plugged into a hollow cylinder, they can be assigned between spacers acting on them. With the spacers can be set a predetermined distance between two mounted on a hollow cylinder grinding tools.
  • Each hollow cylinder has in its peripheral surface at least one longitudinal groove, in which in each case one of the carriers of a carrier body of a stuck on the hollow cylinder grinding tool engages positively.
  • each carrier body inserted on the hollow cylinder is non-rotatably arranged on the hollow cylinder.
  • the hollow cylinder forms a rotating part of the machine drive and takes the plugged carrier body with the abrasive thereon.
  • spacers each in a longitudinal groove positively insertable rod parts.
  • Each rod part is a cut off from a plastic profile bar piece, each having the desired length.
  • In the longitudinal groove of the hollow cylinder can also engage the clamping screw of a clamping ring.
  • Spacers must be relatively accurately sized or dimensioned, which is done by machining. For the user of the grinding tool this means that he must have a variety of manufactured with the highest accuracy spacers or rings - which can be combined with each other in a time-consuming and mübsiger way, if necessary, to set the particular desired distance between two grinding tools on a hollow cylinder.
  • the rod parts make it possible advantageously to cut off a piece of predetermined length, which is then inserted into the longitudinal groove of the hollow cylinder. If the piece cut off from the rod part proves to be too long, it can easily be cut shorter. This measure is familiar to any relevant craftsman.
