Definitions

  • the invention relates to a machine for the finishing of workpieces with a complicated profile, preferably for the polishing of workpieces with a complicated profile, consisting of a rotatable drum in which the workpieces are processed, and a device for feeding and removing the workpieces for Example a manipulator with grippers, the drum having a work area in the shape of a torus, which is surrounded by a floor and by cylindrical walls fastened to the floor.
  • a machine for the finishing of workpieces which consists of a rotatable drum in which the workpieces are processed and of a device for loading and unloading.
  • the facility for the Feeding the workpieces to the drum and removing them after processing is built as a manipulator with grippers.
  • the drum in which the workpieces are processed has a work area in the form of a torus, which is formed by a base and by cylindrical walls which are attached to the base.
  • An abrasive mixture is introduced in the work area (JP-C-46/10 399).
  • a disadvantage of this known machine is that edges are rounded when polishing workpieces with a complicated profile, which is undesirable.
  • the invention has for its object to provide a machine for finishing, for example for polishing workpieces with a complicated profile, with which all surfaces can be machined evenly.
  • the work area in the form of the torus of the drum is closed from above by an immovable magnetic core and that an electromagnetic coil and a disk rigidly attached to the magnetic core are arranged in the center of the work area.
  • the cylindrical walls of the work area with the shape of a torus are made of non-ferromagnetic material, while the bottom, the disc and the axis are made of ferromagnetic material.
  • the bottom of the drum is supported by a flange on the rigid axle.
  • the machine for finishing workpieces with a complicated profile can, for example, have six work stations which are arranged above the work area of the centrifugal drum, which has a lower, rapidly rotating magnetic pole.
  • Any work station is equipped with an electric motor, reduction gear and a spindle to which a chuck for clamping the workpiece is attached.
  • the discreet rotation of all workstations, together with the upper magnetic core, is carried out by a separate electric motor with reduction gear and chain tooth gears.
  • a central contact collector feeds the work stations. In the first working position, the work station is lifted by a pneumatic cylinder, whereby the finished workpieces can be removed and unprocessed ones can be used. In all other positions, the workstations are lowered into corresponding openings in the upper magnetic core.
  • the advantages of the invention are that the quality of the machined workpieces is improved without changing their geometric shape, the machining of all surfaces taking place simultaneously.
  • the machine according to the invention for the finishing of workpieces with a complicated profile consists of a drum 1 which is driven by an electric motor 3 via a belt drive 2.
  • the drum 1 is in a ge housed 4 and has a work area 5 with the shape of a torus, which is surrounded by a bottom 6 and cylindrical walls 7 and is closed at the top by an immovable magnetic core 8.
  • the walls 7 are attached to the floor 6.
  • the bottom 6, the rigid axis 11 and the disk 10 are made of ferromagnetic material, while the cylindrical walls 7 of the toroidal working area 5 are made of non-ferromagnetic material.
  • the bottom 6 of the drum 1 is mounted with a flange 21 on the rigid axis 11.
  • the grippers 12 of the manipulator move upwards again and rotate.
  • the workpieces thereby reach the work area of another, analog centrifugal drum 1, which rotates in the opposite direction.
  • the workpieces are above the starting position. They are removed from the pliers devices 17 by the removal device 19 with the control block 20.
  • the machine shown in FIGS. 3 and 4 has six work stations 21 to 26, which represent identical independent units.
  • Each of the work stations 21 to 26 has a separate electric motor 38 which drives a work spindle 32 via a reduction gear, to which a mandrel 33 is fastened with a workpiece.
  • the individual workstations 21 to 26 each have two ball guides 36, which can move vertically along guides 35.
  • Each mandrel 33 with workpiece passes through a closure 34, which in a corresponding opening in the upper magnetic core 8 (Fig. 2) of the centrifugal drum 27 is inserted and closes the work area 31 from above.
  • the magnetic field in the working area 31 is generated by an electromagnetic coil 28.
  • the magnetic centrifugal drum 27 is driven by an electric motor 30 via a pulley 29.
  • the six work stations 21 to 26, together with the ball guides 36 and the guides 35, are arranged between two disks, the pneumatic cylinders 40 being arranged above the upper disk 39 for vertical movement.
  • An electric motor 43 drives a chain tooth transmission 45, a reduction gear 46 and a second chain transmission 47, 48 and a disk with cams 42 via a clutch 44.
  • the cam 42 can penetrate radial incisions of the dividing wheel 41 (Maltese cross mechanism) and drive the entire system step by step.
  • the compressed air for the pneumatic cylinders 40 is supplied through an air line 51 and a connection 50 and distributed by a pneumatic distributor 37.
  • All electric motors of workstations 21 to 26 are supplied with power via a contact collector 49.
