    The present invention relates to a device for rotatable disc-shaped holders for grinding tools comprising grinding segments weldable in radially directed tapered grooves in the respective holders.
    There is a problem with securely holding grinding segments which are fastened in rotatable grinding wheel holders of the type specified above, especially when the machine is switched off and transported between different workplaces.
    For example, the tie segments can be displaced undetected in the direction towards the center of the hall if the tie segments are subjected to careless handling or if they strike a solid object on the ground, e.g. a pavement stone when the machine is driven on the ground to / from transport vehicles. In such cases, the wedge action between the tie segments and the wedge-shaped grooves in the holder can decrease and in any case disappear completely, whereby they become detached and the tie segment becomes detached and can be lost, which means that a whole batch of new tie segments must be procured and replace the lost tie segment. as the other remaining tie segments. It is important that the tie segments wear evenly in order to e.g. avoid imbalance on the disc but also to avoid uneven sanding of the substrate. The said grinding segments are arranged to be worn down substantially at the level of the front surface of the grinding wheel in which the radial grooves are first I.
    Through JP 11-151675, the edge is to hold the grinding wheel segment with the aid of an enclosing band. This applies to grinding wheel segments which are inserted in radial wedge-shaped grooves from the circumference of the wheel.
    According to CH 523746, it is intended to retain the tie segments in the associated wedge-shaped radial grooves with pivotable lash spindle. The main object of the present invention is therefore primarily that i.a. solve the above-mentioned problem with unintentional detachment of the grinding wheel segments from the grinding wheel, and with simple and selective means.
    Said objects are achieved by means of a device according to the present invention, which is mainly characterized by the fact that between the holder and the tie segment in question a number of magnets are arranged to retain the respective tie segments in the intended holding regardless of working condition, the said number of magnets being arranged / arranged by forming obstacles or by magnetic action retaining the tie segments in the intended holding layers.
    The invention is described below as a pair of preferred embodiments, with reference to the accompanying drawings, in which Figs. 1-5 show a first embodiment of the invention, where Fig. 1 shows the front of a holder in perspective with inserted magnets in recesses stopping a shown fixed tie segment, Fig. 2 shows the holder in perspective without magnets and tie segments, Fig. 3 shows in detail a receiving pair for the tie segment and with transverse magnetic receiving recess, Fig. 4 shows a front view of the holder fully charged with magnets and tie segments, Fig. 5 shows a sectional view along the line VV Fig. 4, Fig. Fig. 6 shows the back of the holder, and Fig. 7-11 shows a second embodiment of the invention, where Fig. 7 shows the front of a holder in perspective with inserted magnets in side-mounted recesses 5 for stopping a shown tie segment, Fig. 8 shows the holder in perspective from front side without magnets and tie segments, Fig. 9 shows in detail a receiving pair for tie segments Fig. 10 shows a front view of the holder with a loaded tie segment, and Fig. 11 shows a sectional view along the line II-II in Fig. 10.
    According to the present invention, which relates to a device 1 at a rotatable disc-shaped holder 2, arranged for receiving grinding tools comprising grinding segments 3 which are releasably attachable in radially 4 tapered grooves 5 in the respective disc-shaped holder 2, are between the holder 2 and the tie segment 3 a number of magnets 6, 7, 8 arranged. Said number of magnets are arranged to retain the respective tie segments 3 in the intended holding regardless of the working length I on the disc-shaped holder 2 and its front surface 2A. In this case the said number of magnets 6, 7, 8 arranged, as shown in Figs. 1-5, to form an obstacle for the tie segment 3 to retain the tie segments 3 in the intended holding layers I or, as shown in Figs. the tie segments in the intended retaining members I.
    A recess 9, which is the bellows in the rear inner Spirit 5A of the respective retaining groove 5, at the center of the groove, i.e. said said spar 5, is shaped to the 4 associated magnet 6 so as to be able to receive said magnet 6, weldable in designed recess 9, in holder 2. Thereby said magnet 6 received in said recess 9 is arranged to prevent return of the tie segment in question. ment 3, which is received in associated radial associated grooves 5 with its salmon tail-shaped cross-section formed bottom portion 10, and congruent to associated grooves 5.
    The depth of said recess 9 is so chosen and the height of the magnet 6 is adjusted so that the magnet 6 received in the recess 9 extends to a level which exceeds the bottom portion of the tie segment 3, and that said recess 9 is the transverse retaining pair 5 in the associated part of the holder 2 .
    According to the embodiment of the invention, shown in Figs. 1-5, the placement of the magnets 7-8 is arranged in paired recesses 11, 12, which are wholly or partly hidden by radially directed retaining grooves 5 in the former tie segment 3. 12, which are arranged to receive their respective magnets 7, 8, are shaped to said magnets 7, 8 and the respective recesses 11, 12 have a depth which essentially corresponds to the thickness of the associated magnet 7, 8. The recesses 11, 12 are located at the periphery of the holder 2 with a recess 11, 12 on each side of the spare 5. The magnets 7, 8 and the associated congruent recess 9 / recesses 11, 12 have a generally square shape and preferably rectangular gold. form.
    One or more cavities 13 are beldget / belAgna at the edge of said recess 9; 11, 12 have a gripping interaction between one in the recess 9; 11, 12 received magnet 6-8 and the edge of said recess, for example with a knife, screwdriver or other tool.
    S Removal of tie segments according to the design of the first example takes place by using e.g. a knife pokes the magnet 6 loose and so that the tie segment 3 can be displaced in the associated groove 5 and then can be lifted loose from the groove 5, for possible replacement etc.
    According to the second example, the magnets 11, 12 do not have to be removed from the holder 2, but the handle is gripped hard in the tie segments 3 and allowed to slide radially towards the center 2B of the holder so that the grip frail the magnets 11, 12 relaxes and the tie segments 3 then come loose. from the hall.
    In reverse order, fasten the tie segments 3 to the holder 2.
    Of course, both the holder 2 and 15 consist of the tie segments 3, At least its fastening parts, which cooperate with the magnets 6; 7, 8, of metal or other material to which magnets adhere.
    The invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, especially when it comes to the nature of the various parts, or by the use of equivalent technology, without departing from the scope of the invention as defined in the claims. 6
