Definitions

  • An improved multistation automatic bulb inserting inslot coil winding machine having four stator supporting positions each of which is adapted to releasably hold the appropriate number of tooling bulbs in conjunction with a stator. Two stations insert and remove these tooling bulbs and actuate the mechanism within the turn table for securing the bulbs while the other two stations having unique tooling bulb supports which have winding needles for performing the in-slot winding operation.
  • Nill et al. patent. ,A winding ,head which may have a single wire dispensing needle or several wire dispensing needles, four as shown in Nill being a useful and practical arrangement, execute an axial motion while the needle is dispensing wire in the stator slot and then executes a combined axial and rotary motion so as to form an end turn in the coil and begin dispensing wire in a diflerent stator slot in the opposite direction.
  • the process is repeated for example, the needle passing upwardly in a given stator slot then forming a loop and an endturn of wire and passing downwardly in an adjacent stator slot and hence forming a second or bottom end turn so as to be able to again pass upwardly in the original stator slot.
  • the wire at the upper and lower endsof the stator which serves to connect the two stator slots in which wire is being laid will interfere with or partially block the stator bore.
  • Tooling bulbs are provided in the stator to ensure that this wire does not block the stator bore and to properly form these end turns during the winding operation.
  • the present invention provides an automated scheme for inserting and locking tooling bulbs in winding position in a stator supporting turntable, then revolving that turntable to an in-slot winding location where the stator coils are wound, then returning the thus wound stator and end turn forming bulbs to a location where the bulbs are automatically unlocked and removed such that the only hand operation required is the insertion and removal of the unwound and wound stator respectively.
  • Yet another object of the present invention is to provide a multistation winding machine having improved automatic tooling features.
  • FIG. 1 is a perspective view of a multistation automatic in-slot coil winding machine according to the teachings of the present invention
  • FIG. 2 is a top view of one of the four turntable locations of FIG. 1; v
  • FIG. 3 is a top view similar to FIG.2 showing a stator and a pair of tooling bulbs in position;
  • FIG. 4 is a perspective view of the bulb inserting head
  • FIG. 5 shows the variable stator height provision in the present invention.
  • FIG. 1 illustrates a four station automatic in-slot coil winding machine according to the teachings of the present invention.
  • the machine has a two level turntable 11 which supports four stator supporting locations 13, 15, 17 and -19 which are identical in their fundamental structure and each of which is shown in position over a corresponding station of the machine.
  • the two locations near the front, that is 17 and 19 are locations at which a stator will be inserted, the tooling bulbs will be inserted and locked in position and from which, after the turntable has indexed twice about its axis 25, the tooling bulbs will be removed and the completed wound stator removed.
  • the two rearward locations, that is l3, 15 are over respective winding heads 21 and 23 which, as illustrated, simultaneously in-slot wind four coils in the stators.
  • the structure beneath the two winding heads 21 and 23 is basically that described in my aforementioned application Ser. No. 76,697 entitled DRIVE FOR IN-SLOT WIND- ING MACHINE while the structure beneath the two forward locations will be described in greater detail in reference to FIG. 4.
  • each of the two front stations would have a bulb inserting head 27 of FIG. 4 and each of these heads would be connected to the primary source of power within the winding machine to be moved axially along its axis 29, to be rotated slightly about that axis 29, and to have the centrally located gear 31 turn-so as to revolve each of the tooling bulbs substantially 180.
  • the system must of course be programmed so that each of these motions occurs at the proper time.
  • the bulb inserting head itself is seen to have an internal driving gear 31 and the appropriate number of driven gears 33 so as to rotate each of the same number of bulb supporting rotatable dovetail slot means 35.
  • the supports 35 of course mate with corresponding flaring tenon portions 37 on the lower end of each of the tooling bulbs.
  • the tooling bulbs themselves are seen to have a pair of bulb ends 39 and 41 which are for positioning and forming the end turns of a stator winding and the tenon portion 37 is seen to be on the back side of the lower bulb portion so that in operation this tenon portion will not interfere with the end turn forming function.
  • the configuration of the middle portion of these tooling bulbs in arbitrary except as will appear in conjunction with the discussion of FIG. 2 and serves only to connect and maintain the relative position of the two bulb ends.
  • FIG. 2 illustrates a top view of one of the four turntable locations without a stator or any of the tooling associated with the station over which this location might be at a particular time.
  • FIG. 3 is an almost identical view, however, a stator, a pair of tooling bulbs and the bulb inserting head are also illustrated in FIG. 3.
  • the turntable 1 1 of FIG. 1 is a two level turntable and each of the levels will have the basic structure of FIG. 2, that is this structure is repeated both above and below a stator.
  • the structure of FIG. 2 performs the basic function of holding thetooling bulbs in position once they have been inserted by the bulb inserting head of FIG. 4.
  • This structure has a set of radially sliding hooks 43 and a set of radially sliding retainers 45 which as noted earlier are duplicated on both the upper and lower levels of the turntable.
  • the hooks 43 are slid radially simultaneously by the revolution of the annular ring 47 and the corresponding lower set of hooks is identically actuated by a corresponding annular ring, the upper and lower annular rings being actuated by a series of pins 49 so that all hooks and all retainers move together.
  • the upper and lower levels of the turntable may be moved together or apart each moving an equal distance from a center line between them and in opposite directions so as to allow the winding of stators of different lengths by the simple expedient of using tooling bulbs of the appropriate length and adjusting two levels of the turntable accordingly.
  • the upper and lower annular rings pass over the pins 49 but are slidable on those pins in the direction of the axis of those pins. If the ring 47 were to be rotated counterclockwise from its present position, a pin 51 riding in a slot 53 would follow that slot and thus slide the hook 43 radially outward so as to clear the central portion of the location.
  • the sliding retainers 45 communicate by means of pins 55 with a slot 57 in an inner annular ring 59 and rotation of that inner annular ring in a clockwise direction as illustrated in FIG. 2 results in the retracting radially outwardly of the retainers 45.
  • FIG. 3 the same basic structure of the upper level of the turntable location illustrated in FIG. 2 is shown carrying like reference numerals.
  • the sliding retainers 45 must be retracted by rotating the annular ring 59 in a clockwise direction.
  • the radially sliding hooks 43 must be retracted by sliding the annular ring 47 in a counterclockwise direction.
  • a stator 61 is placed in this turntable location and supported in a position where the lower level turntable hooks and retainers may slide radially below the stator while the upper level hooks and retainers for that same location will slide radially above that stator.
  • the bulb inserting head 27 carrying the tooling bulbs and having the slot means 35 and the tooling bulbs in the orientation illustrated in FIG. 4, that is where the actual surfaces of the bulb portions are turned 180 away from the direction in which they must face for winding, is inserted.
  • the bulb inserting head travels upwardly carrying the tooling bulbs through the bore of the stator and stopping at a point where the notches 63 are at the same level as the upper retaining and hook means while the notches 65 of FIG. 4 are at the same level as the corresponding sliding retaining and hook means of the lower level of the turntable.
  • the driving gear 31 is rotated so as to turn each of the driven gears 33 associated with a tooling bulb through so that the bulbs now take on the position shown in FIG. 3.
  • the next step is to rotate the annular ring 47 in a clockwise direction so that the hooks 43 slide radially inward.
  • this turntable would index 180 so that the two locations 17 and 19 containing a stator and the tooling bulbs locked in position would be presented to the two winding locations at the rear of the machine.
  • the two winding heads 21 and 23 would then perform an in-slot winding operation while at the same time two unwound stators would be inserted in the front locations and tooling bulbs inserted and locked within those stators according to the foregoing sequence.
  • FIG. 5 broken away portions of the two levels of the turntable 11 are illustratedin cross section as being joined by a threaded member 66.
  • the winding machine to be versatile must be capable of handling stators of different heights which may be accomplished by varying the separation between the two levels of the turntable. To be compatible with the winding mechanism, it is desirable when effecting this variation in the separation of the two levels to move the top level of the turntable upward and the lower level of the turntable downward in equal amounts so that the two levels are uniformly distributed above and below a hypothetical fixed center plane.
  • the pins 49 should be made slidable relative to one or preferably both of the turntable levels so that this adjustment may be easily efi'ected.
  • the actual adjustment of the separation between the two turntable levels is effected by the threaded member 66 which has a first threaded portion 68 and a second threaded portion 70 engaging the upper level of the turntable and some support element 72 respectively. If the pitch of the threaded portion 68 is made to be double that of the threaded portion 70 rotation of the member 66 in one direction will result in the lowering of the lower level of the turntable and the corresponding raising of the upper level of the turntable so that their respective distances from a hypothetical center plane remain equal.
  • the specific scheme shown in FIG. 5 requires that the lower level of the turntable be rotatably affixed to the member 66. It should be clear from this drawing that various combinations of differently pitched left or right hand threads might be used to engage any combination of the upper and lower levels of the turntable and the support member to effect the same result.
