Definitions

  • the invention relates to an abrasive wheel with overlapping Abrasive flaps arranged in a fan shape on a carrier element are, according to the preamble of claim 1.
  • Such grinding wheels have been manufactured for a long time and sold.
  • An example of the grinding wheels known up to now in this type consist of a plastic carrier element in the form of a Disc on which individual grinding lamellae fan-shaped are overlapping in the overall shape of a ring.
  • the support element is in the center with the exception of a hole the disc, which is the attachment of the grinding disc to the Grinding machine is used, trained throughout.
  • the support element is only the outer diameter in terms of its shape adapted to the ring formed by the grinding flaps.
  • the fan-shaped arrangement of the grinding flaps serves one Self-renewal of the abrasive.
  • This arrangement ensures a constant high removal rate of the grinding wheel.
  • the abrasive of all lamellas can cause constant surface quality of the workpiece can be achieved.
  • the special slat structure ensures cool and steamed Ground and thereby prevents tarnishing of the surface of the Workpiece.
  • a grinding wheel is described in JP 02015979, which consists of a carrier element in the form of a disc, on which individual grinding lamellae fan-shaped overlapping in the form of a ring on both sides of the carrier element are attached.
  • the fan-shaped layering the grinding flap runs on both sides of the grinding wheel in the same direction, i.e. the stratification of the Grinding lamella is in the same direction.
  • This same direction allows simultaneous editing of two opposite ones Sides of a groove, furrow or groove.
  • this grinding wheel is the existing risk of injury through radially accelerated removal of the workpiece and its short service life.
  • the invention is based on the object, the Consumption of material for the production of the carrier element while increasing the service life of the grinding wheel to reduce without the good grinding properties of the lose already known execution.
  • Another object is to manufacture a fastening device for ring-shaped grinding wheels regardless of the structure of your grinding surface.
  • the invention provides for the manufacture of grinding wheels, where the overlapping fan-shaped grinding lamellae on both sides of the same support element in opposing stratification to form a grinding surface are attached. Because that's for this type of grinding wheel common drive motors have only one direction of rotation, allows the opposing layering of the grinding flaps successive or alternating use of both Grinding surfaces with one and the same drive motor, which for considerable increase in tool life leads.
  • the drive motors generally used in practice for this type of grinding wheel are angle grinders.
  • a reduction in the carrier element material consumption will achieved in that the shape of the carrier element essentially corresponds to the grinding surfaces by the overlapping fan-shaped grinding lamellae formed become. With this almost congruent adaptation of the Support element to the overall shape of the grinding surface arise no superfluous ones not covered by grinding flaps Areas on the support element.
  • To attach the A grinding device is used on a grinding machine on a grinding machine, those with specially designed recesses is to be releasably engaged in the grinding wheel.
  • a preferred embodiment is the formation of the carrier element and the overlapping fan-shaped arranged grinding flap formed grinding surface as Ring.
  • this fastening device in two parts.
  • the training takes place in the form two holding elements, which the carrier element non-positively fix and detachable by mounting with e.g. screws enclose between themselves, in possible combination with positive elements that the support element without hold the final fixation in an immovable position.
  • the fastening device for ring-shaped grinding wheels with on a support element arranged on both sides grinding surfaces.
  • the fastening device is advantageous by two together releasably connected holding elements realized, which enclose the slip ring non-positively and / or positively, one of the two holding elements with the Protective cover can be inextricably linked.
  • the connection Holding element and protective cover is in another Embodiment releasably connected in two parts.
  • the grinding wheel realized in the present invention the special one in terms of material saving and disposal Has advantages is due to the completely new concept of the Complete system (grinding device and fastening device) further optimizable.
  • the thought of the least possible Material expenditure was with the exchangeable fastening device consistently continued.
  • With the fastening on both sides of grinding flaps on the carrier element was in Difference from the prior art a protective device for the side of the grinding wheel facing the grinding machine integrated. This function was combined according to the invention realized with the developed fastening device.
  • the grinding wheel according to the invention has 1 fan-shaped overlapping on both sides Abrasive flaps 2, which are attached to a carrier element 3 are.
  • 2 is the opposite stratification of the Abrasive flaps 2 shown. This opposite stratification leads to the formation of two grinding surfaces 4, which alternatively can be used with the same drive motor.
  • the support element 3 is in the particular embodiment shown as annular body formed with an outer diameter of 115 mm and an inner diameter of 57 mm. These dimensions however, in no way impose a limitation The disc can be made in any diameter. The most common outside diameters are around 115 cm, 100 cm, 125 cm and 180 cm.
  • this carrier element 3 On this carrier element 3 is a Grinding surface 4 by 72 rectangular grinding flaps 2, which have dimensions from 17 mm to 24 mm, wherein the overlap is formed such that approximately 5 mm grinding surface per grinding flap not through the next grinding lamella above is covered. Also here are the dimensions of the grinding flaps no limitation. The shape and dimensions are the same according to the application and the size of the grinding wheel. The dimensions of the annular grinding surface thus formed 4 is 115 mm in outside diameter and 65 mm in inside diameter.
  • the grinding flaps 2 are shown in FIG glued special embodiment. Alternatively, it is also possible the grinding flap mechanically or on others Way to attach, e.g. the carrier element 3 in the injection molding process produce while doing the grinding lamella 2 at the same time to fix.
  • the carrier element 3 can also be made of a material other than plastic, e.g. made of metal, Metal alloys, or any other suitable for this purpose Material. That through the ring-shaped training of the grinding body 1 formed recess 5 serves as seen in Figure 2, the inclusion of the fastening device 6.
  • the fastening device 6 shown consists of two Holding elements 7 and 8, the holding element 7 as the end face 10 of the fastening device 6 with the grinding body 1 forms a surface.
  • the other holding element 8 is in the special case with a protective cover 12 for the Grinder facing side 9 of the grinding body 1 inextricably linked.
  • the support element 3 is non-positive and / or positive on.
  • the non-positive attachment is carried out by means of a Screw connection by means of the holding elements 7, 8 Threads 13.
  • the fixation of the carrier element 3 to the Grinding machine is done using mechanical tools that can engage in the holes 11 and 14.
  • the inner circumference of the carrier element can also e.g. serrated be or be provided with protrusions that are complementary Intervene surfaces of the holding elements 7 and 8. To this Form-locking between the holding elements can also be done in this way 7, 8 and the carrier element 3 reach.
  • Figure 4 shows a further embodiment of the fastening device 6.
  • the end holding element 10 is in formed in the same way as shown in Figure 2.
  • the Holding element 8, which in Figure 2 is inseparable from the protective cover 12 is realized as a disk in FIG. 4, that does not reach the diameter of the grinding wheel 1 and thus only as a counter bearing to the holding element 10 Fixing by means of threaded rod 13 is used.
  • Figure 5 shows the abrasive body 1 according to Figure 1, the Holding element 8 is not connected to the protective cover 12 is.
  • the protective cover 12 shown in Figure 5 is one separate version and is with a spacer 15 with With the help of the thread 13 on the two holding elements 7 and 8 attached.
  • the end face also forms in this embodiment the fastening device 10 a disc with the Grinding body 1 and the side facing the grinding machine 9 of the grinding body 1 is protected by the protective cover 8.
