Definitions

  • ABSTRACT A rotary stand comprises an annular track, an annular [30] Foreign Application Priority Data Nov. 9, 1970 France.........v................. 7040208 rotor revolvably mounted on said track including an armature ring cooperative with at least one inductor fixed relative to said track, said rotorhaving attached 72 W60 2/ B n m 8 1 OW Hmm 9 6 65m 119 /6 u 0 U 1 3 H L L C C S L U m U U 5 5 thereto carriages movably supported on an annular runway concentrically surrounding said track.
  • Revolving stands for moving workpieces to a selected series of work stations comprise a circular table or a frame having arms delimiting a plate, and such table or frame is rotatively driven by a central shaft or an annular rack engaged with a driving gear.
  • These well known structures utilized in many industries, cannot readily be adapted to very large diameter revolving stands, for example with a diameter greater than 10 meters. because they would involve very heavy constructions, difficult to produce and operate, and thus very expensive.
  • the circular shape of the known revolving stands it is compulsory to provide the frames, supporting the working stations, in the shape of a swanneck or T.
  • the present invention comprises a new structure enabling the construction of revolving stands of any size
  • the automotive structure for revolving stands includes a fixed annular track, an annular rotor movably supported by wheels and rollers engaging said track, said rotor including a conductor ring forming an armature which is placed in parallel withat least one inductor set fixed in the vicinity of said track, and carriages coupled to and extending radially from said rotor, said carriages being movably supported by wheels engaging a fixed runway disposed concentrically of the rotor and track.
  • the automotive structure forming a rotary or revolving stand comprises an annular runway or track 1, preferably of L section as shown in FIG. 2.
  • the track 1 can be set directly on the ground or can be supported above the ground by spaced posts 2 or setup any other way depending on the particular type of machine.
  • the track 1 supports a rotor 3 comprising an annular frame 4 (FIG. 2) to which is fixed a metallic continuous ring 5, for example composed of two superimposed components, one component of steel and the other of copper.
  • the frame 4, when continuous, preferably is composed of channel iron, leaving the area bounded by the rotor 3 and the ring 5 entirely free.
  • the frame 4 is provided with brackets 6 supporting said frame on wheels 7 running on the track I, and with centering rollers 8 disposed at right angles with the wheels 7 and bearing against the upstanding flange of the track 1.
  • the number of wheels 7 and rollers 8 depends on the diameter of frame 4 and on the loads that said frame may have to support. However, the minimal number of each set of wheels 7 and rollers 8 is three, to ensure steadiness to the rotor 3.
  • the frame 4 also includes, at spaced points, coupling components 9, for example constituted by fork joints, to which are connected arms 10 of carriages l1 supported by wheels 12 resting on an annular runway 13 which concentrically surrounds in spaced relation the track 1.
  • the runway 13 comprises a planar ring supported by spaced posts 14 but this runway also can be directly mounted on the ground and may also comprise an undulatory ring whereby the carriages 11 may rise and fall, if ncessary, for example to lift or lower them at selected stations.
  • at least one electromagnetic inductor 15 is disposed in fixed position beneath the rotor 3, specifically, beneath ring 5.
  • the inductor 16 is, for example, supported by a bracket 16 on a post 2.
  • the inductor 15 is disposed in cooperative relation with ring 5, which thus constitutes the rotary armature or rotor of an electric motor.
  • ring 5 which thus constitutes the rotary armature or rotor of an electric motor.
  • changes in rotor diameter due for example to expansion phenoma have no effect on the gap therebetween.
  • the number of fixed inductors l5 depends on the rotor size and on the power supplying the rotor to drive and alternately slow down the carriages 11 that it has to move.
  • the foregoing structure leaves entirely free the area encompassed by rotor frame 4, and the diameter thereof can be of any size, thereby enabling construction of revolving stands of very large size and easily adaptable for various processing operations.
  • This rotor can be coupled with any number of carriages 11 which can be made as desired concerning both their shape and size.
  • tools 20 easily can be placed beneath the runway 13, thus adapting the automotive structure for many applications in which it is necessary to successively bring workpieces to different work stations which can be of a complex nature.
  • a rotary stand comprising:
  • carriages for workpieces revolvably mounted on said runway and connected with said radially disposed means.
  • said track and said rotor are annular so that the surrounded area is free of obstructions.
  • a rotary stand according to claim 3, comprising:
  • carriages for workpieces revolvably mounted on said runway and connected with said radially disposed means.
  • a rotary stand according to claim 7, wherein said rotor comprises an annular frame supporting said armature ring and has secured thereto brackets each supported by one said wheel and carrying one said roller, said frame also supporting protruding members constituting said radially disposed means.
  • protruding members comprise fork joints for hinged coupling with said carriages.
