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.
- a grinding wheel is from DE-U-90 02 384 known.
- 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 overlap in a fan shape are attached in the overall shape of a ring.
- the support element except for a hole in the center of the disc, the attachment of the grinding wheel to the grinding machine serves continuously trained.
- the support element is regarding its shape only the outer diameter of the by the Adjusted grinding flap formed ring.
- the fan-shaped arrangement of the grinding flaps serves one Self-renewal of the abrasive.
- This arrangement ensures a consistently high level Removal rate of the grinding wheel. Until complete wear the abrasive of all lamellas can have a constant surface quality of the workpiece can be reached.
- the special slat structure ensures cool and muted grinding and avoids thereby tarnishing 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 overlap in a fan shape Form of a ring attached to both sides of the support element are.
- the fan-shaped layering of the grinding flaps runs in the same on both sides of the grinding wheel Direction, i.e. the layering of the grinding flaps is in the same direction. This same direction allows simultaneous Machining two opposite sides of a groove, furrow or groove. Disadvantages of this grinding wheel are the existing ones Risk of injury due to radially accelerated removal from the workpiece and its short service life.
- the object on which the invention is based consists in the production of a fastening device for ring-shaped grinding wheels, the safety during the processing of workpieces with such grinding wheels should be increased significantly.
- the carrier element preferably has at least one recess, which with the fastening device for fastening the grinding wheel is releasably engageable with a drive motor.
- a preferred embodiment is the formation of the carrier element and that by the overlapping fan-shaped arrangement Sanding flaps formed as a ring.
- the fastening device has a protective cover, which is the side of the grinding body facing the grinding machine completely covers.
- the fastening device is advantageous realized by two detachably connected holding elements, which the slip ring non-positively and / or positively include, one of the two holding elements with the Protective cover can be inextricably linked.
- the connection Holding element and protective cover is in a further embodiment detachably connected in two parts.
- the grinding wheel realized in the present invention the special advantages in terms of material savings and disposal is due to the complete redesign of the overall system (Grinding device and fastening device) optimizable.
- the idea of the lowest possible material expenditure became consistent with the exchangeable fastening device continued.
- With the fastening of grinding flaps on both sides in contrast to the state of the Technology a protective device for the facing the grinding machine Integrated side of the grinding wheel. This function was according to the invention together with the developed fastening device realized.
- the grinding wheel 1 Abrasive flaps arranged in a fan-shaped overlap on both sides 2, which are attached to a carrier element 3.
- Fig. 2 the opposite stratification of the grinding flaps 2 is shown. This opposite stratification leads to the formation of two Grinding surfaces 4, alternatively with the same drive motor are usable.
- the carrier element 3 is shown in the special one Embodiment designed as an annular body with an outer diameter of 115 mm and an inner diameter of 57 mm. However, these dimensions in no way represent one Limitation.
- the disc can be made in any diameter become. The most common outside diameters are 115 cm, 100 cm, 125 cm and 180 cm.
- the abovementioned dimensions of the grinding flaps are not limited The shape and dimensions depend on the application and the size of the grinding wheel.
- the dimensions of the so formed, annular grinding surface 4 is 115 mm in Outside diameter and 65 mm inside diameter.
- the grinding flaps 2 are glued in the special embodiment shown. Alternatively, it is also possible to use the grinding flaps mechanically or otherwise, e.g. the support element 3 in the injection molding process and thereby the To attach the grinding flaps 2 at the same time.
- the support element 3 can also be made of a material other than plastic, e.g. out Metal, metal alloys, or any other for these purposes suitable 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 being the end face 10 the fastening device 6 with the grinding body 1 a surface forms.
- the other holding element 8 is special Case with a protective cover 12 for that of the grinder facing side 9 of the grinding wheel 1 is non-detachably connected.
- the two holding elements 7 and 8 close the Carrier element 3 non-positively and / or positively.
- the non-positive Fastening takes place by means of a screw connection on the holding elements 7, 8 threads 13.
- the fixation of the support element 3 to the grinding machine by means of mechanical tools which are drilled in the boreholes 11 and 14 can intervene.
- 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 FIG. 2 cannot be detached from the protective cover 12 is realized in FIG. 4 as a disk which does not reach the diameter of the grinding wheel 1 and thus only as a counter bearing to the holding element 10 by means of fixation Threaded rod 13 is used.
- FIG. 5 shows the grinding body 1 according to FIG. 1, the holding element 8 is not connected to the protective cover 12.
- the Protective cover 12 shown in Figure 5 is a separate embodiment and is with a spacer 15 using the thread 13 attached to the two holding elements 7 and 8. This one too Embodiment forms the end face of the fastening device 10 a disc with the grinding wheel 1 and the Grinding machine facing side 9 of the grinding body 1 protected by the protective cover 8.
