Definitions

  • the present invention relates to a machine for the automatic insertion of prefabricated slot insulations and- /or cover caps or armature insulations into stators or armatures of electric machines, in which the workpiece to be equipped is held by a receiver, which is rotatable stepwise as part of an index plate.
  • the automatic insulating machines which are already known, however, require improvement with respect to the said demands. This is particularly due to the fact, that the insulation parts must here be pushed through by the receiver for the workpiece to be equipped, i. e., the receiver part for the stator must have as many slots as the stator itself, since the inserting tool is arranged at the bottom.'This has the result, that the insertion of the insulation strips must be effected through the surface of the receiver part.
  • the latter must therefore be provided with a rim of passage openings corresponding to the slot pitch of the workpiece to be fitted, which openings must be of the samecross-section, so that the insulating strip can be pushed through and into the slots of the workpiece by the tool without obstacle.
  • the receiving part here can be used only for a given diameter of the slot pitch circle in the workpiece and also only for a given size slot. Because of these properties, a correspondingly complicated construction of the known automatic insulating machines results which has a detrimental effect on the cost price as dial distance from the axis of rotation thereof,in which connection in each case one receiver withthe workpiece is directly below the insertion tool, and the insulating strips to be inserted can be inserted as individual pieces in the operating cycle of the index plate by the tool, preferably from above.
  • the invention makes still another proposal in accordance with which the receiver is made axially displaceable, the displacement being controllable in such a manner that the insulation strips upon the insertion can be passed without spacing into the slot of the workpiece, and that after termination of an insertion process, the workpiece is moved back into a distance from the insertion tool, which is necessary for the unimpeded further movement of the workpiece.
  • the insertion tool is, in accordance with the present invention, displaceable into a diametrical position transverse to the axis of rotation of the receiver.
  • FIG. 1 is a side elevation of the machine; and FIG. 2 is a top plan view of the machine shown in FIG. 1.
  • the circular indexing 7 table 2 is swingably supported (arrow B-B) around an axis A on a base 1.
  • This table 2 bears two index plates 3 and 4, each of which is provided on its periphery with an indexing gear rim 5.
  • the pitch of these gear rims 5 corresponds to the pitch of the slot rims 6 in the workpiece 7, 8 which in the present example is shown as stator of an electrical machine.
  • Each-index plate 3, 4 is provided with a receiver 9 for the workpieces 7, 8, which is connected fixed for rotation with the index plates 3and 4, respectively, and can carry out controlled movements (arrow CC) in the direction of its axis of rotation.
  • the insertion tool 10 is arranged over the workpieces 7, 8 and provided with an insertion ram 11 which carries out controlled movements in the direction indicated by the arrows DD and in this connection pushes the insulating strips into the slots 6 through the mouthpiece l2.
  • the insertion tool 10 can be displaced transversely in the direction indicated by the arrows E-E, so that it can be brought into a diametrical position with respect to the axis of the workpiece (for instance 8) which is below the tool 10.
  • receiver 9 for the other workpiece 7 has been brought into its lower end position where it stops and can be provided with the workpiece 7 which is to be equipped.
  • the index plate is turned step-by-step in synchronism with the insertion tool by a stepping mechanism (not shown), the pawl of which cooperates with the stepping gear rim 5.
  • the receiver 9 together with the workpiece moves downward an amount which is sufficient to bring the protruding flanged edge of the insulating strip completely out of the too].
  • the insertion tool 10 cooperates directly with the receiver 9 and its workpiece 7 or 8, respectively, so that no passage openings are any longer necessary in the stator-receiver.
  • the flanging, stamping and cutting station (not shown) which is connected with the insertion tool can operate also in known manner automatically, so that, for instance, cover slides, armature insulations and special insulations can also be made.
  • the vertical arrangement of the machine shown is not absolutely necessary, since the machine, without any impairment in its functions, can also be arranged horizontally.
  • This has the additional advantage that even in the case of heavy and large stators, the receiving of the stationary workpiece to be equipped can take place during the insertion of the insulation parts into the other workpiece.
  • stators which can have a total weight of 200 kg and more
  • the removing and placing on of the stator requires a large amount of time, which is dispensed with in the arrangement according to the present invention, since during the equipping of the one stator, the other can be placed on or removed. In this way the purchase cost of such a machine becomes for the first time economical.
  • a machine for the automatic insertion of prefabri cated slot insulations or cover caps or armature insulations into stators or armatures or electrical machines comprising at least two receivers holding a workpiece to be equipped,
  • said receivers being rotatable in stepwise fashion as I part of an index plate, and arranged diametrically on a movable circularindexing table and at the same radial distance from its axis of rotation,
  • said insulating strips, to be inserted being insertable as individual pieces in synchronism with said index place by said tool.
  • said displacement being controllable such, that said insulation strips upon insertion can pass without spacing into said slot of said workpiece, and upon completion of said insertion procedure, said workpiece is moved back into a distance from said inser tion tool required for the unimpeded further movement of said workpiece.
