Definitions

  • the invention relates to a tool with a support member and a disk-shaped Working part for machining.
  • Such tools in which a support member or a base body respectively is connected to a working part, which is a wearing part, are in various configuration known.
  • Supporting part and working part are usually driven in rotation.
  • a coupling part with a female thread attached In known designs is at the working side opposite side a coupling part with a female thread attached, which is screwed onto a thread of a support member.
  • connecting and disconnecting the working part from the supporting part is laborious or time consuming or just with great care to accomplish. This in particular, because such workpieces very often after a very short time have to be replaced.
  • the stack height of the working parts very large, since the coupling part with the nut thread inevitably has a considerable height.
  • the invention is therefore based on the object, a tool of the general Genus in such a way that the production and release of the compound between support member and working part very quickly and easily feasible is.
  • the working part is a coupling part having held on the support member by means of magnetic forces becomes.
  • the working part is a coupling part having held on the support member by means of magnetic forces becomes.
  • the tool shown in the drawing consists in its basic Structure of a support member 1 in the form of a support plate and a Working part 2.
  • the support part 1 has an existing elastic plastic Support housing 3, which has an annular contact surface 5.
  • the support member 1 On its side facing away from the contact surface 5, the support member 1 a concentric with the central axis 6 arranged threaded bore 7, in which a drive shaft 8 of a tool drive, not shown screwed by means of a corresponding external thread 9 can be.
  • Such tool drives may be so-called Angle grinding machines or to act straight-grinding machines.
  • a Holding body 10 is arranged, in which the bore 7 is formed and the concentric with the axis 6 a shallow recess 11 with polygonal Cross section has.
  • a cutout 13 is provided in each case.
  • a permanent magnet 14 in the form of a flat circular disk arranged and fixed to the holding body 10, for example by gluing.
  • the holding body 10 is expediently made of non-magnetizable Material, but can also be made of ferromagnetic material or partially made of ferromagnetic material, for example in the form a composite material.
  • the actual working part 2 is also formed circular disk-shaped and has a counter-abutment surface 15, which in the attachment of the Working part 2 on the support member 1 against the contact surface 5 comes to rest.
  • the working part 2 has approximately the diameter or the circumference of the supporting part 1 on.
  • the working part 2 by an abrasive 16 formed on pad 17, wherein the counter-contact surface 15 on the the abrasive 16 side facing away from the pad 17 is formed.
  • Such abrasive 16 on pad 17 are usually flexible, thus formed elastically yielding.
  • a coupling part 19 made of ferromagnetic material attached. It has a polygonal shape, that of the recess 11 essentially corresponds, d. H. in this case it is an equilateral and equiangular hexagon whose flanks 20 when inserted into the recess 11 for resting against the flanks 12th the recess 11 come, creating a rotationally fixed connection between Working part 2 and supporting part 1 is produced.
  • the coupling part 19 is made of ferromagnetic material, it is due to the magnetic Attraction by the permanent magnet 14 fixed in the recess 11 held. The magnetic forces act in the direction of the axes 6, 18.
  • the coupling part On the side facing away from the counter-surface 15, the coupling part has 19 a flat projecting circular centering approach 21, which is tangent to the six flanks 20 of the coupling part 19.
  • this centering approach 21 inserted into the recess 11, whereby the centering made is.
  • the working part 2 with the coupling part 19th be twisted until the flanks 20 with the flanks 12 in coverage come, so that then the coupling part 19 to rest against the Permanent magnet 14 or leaving a small air gap in its proximity comes and the counter-investment area 15 against the investment area 5 applies.
  • the trained between support part 1 and 2 working part Schnell-Befest Trents-System thus has three sub-functions, namely the axial attachment of the working part 2 and its holder during the Labor on the support part 1 by magnetic forces, the form-fitting Torque transmission between the flanks 12 and 20 and the centering during assembly by the insertable between the flanks 12 Centering approach 21.
  • the ratio of the largest diameter D 19 of the coupling part 19 to the axial thickness d 19 of the coupling part 19 is 5 ⁇ D 19 / d 19 ⁇ 100 and preferably 10 ⁇ D 19 / d 19 ⁇ 30.
  • the ratio of the largest diameter D 19 of the coupling part 19 to the diameter D 14 of the permanent magnet is: 1 ⁇ D 19 / D 14 ⁇ 2.
  • FIGS. 5 to 7 differs from the previously described embodiment only in details. It will therefore without re-explanation for the same parts the same reference numerals. As far as functionally the same, but constructively different parts exist are the same reference numbers, but with a superscript Dash used.
  • the threaded hole 7 is the contact surface 5 open.
  • the recess 11 ' is bounded by flanks 12', which form about an equilateral polygon, with the individual flanks 12 'are bent in the direction of the axis 6 out and where the meeting points or intersections of abutting edges 12 'to rounded Corners 22 are formed.
  • the working part 2' a Clutch part 19 ', whose all-round flanks 20' in their Shape and size of the flanks 12 'of the recess 11' correspond, so that upon engagement of the coupling part 19 'in the recess 11' the Flanks 20 'abut the flanks 12'.
  • the flanks 20 ' are with rounded corners 23 joined together, giving the rounded corners 22 are adjusted.
  • the flanks 12 'of the recess 11' are of the Plant surface 5 away in the holding body 10 'in toward each other inclined.
  • the flanks 20 'of the coupling part 19' inclined towards each other, so that when inserting the coupling part 19 'in the recess 11 'not only a rotationally positive fit, but also a centering to the central axis 6 takes place.
  • the coupling part 19 ' is one of the threaded bore 7 in size and location corresponding opening 24th designed so that - under appropriate conditions from the prime mover forth - the drive shaft shown in the first embodiment 8 may possibly also protrude through the tool.
  • the diameter ratios and thickness ratios apply the comments on the first embodiment.
  • the contact surface 5 may be a continuous flat surface, they but can also be defined by a variety of ribs that are not in the Individuals are shown because it does not matter here.
