MACHINE} FOR PEGGINGOR KEYING ARMATURE'WINDINGS Filed Feb. 28, 1950 2 SHEETS-SHEET 2 Patented Dec. 2, 1952 William Swift, Sutton Coldfield, England, as-
signor to Joseph Lucas Limited, Birmingham,
England ApplicationrFebruary 28, 1950, Serial;No. 146,7 65 'In'Great Britain March 3, 1949 1 Claim. 1
In the construction of an armature for a dynamo-electric machine, it :is usual to secure the windings (after these :have been placed in slots in the armature) by lengths of material which are inserted in the slots for pegging or keying the windings in position. The slots are usually so ishaped that the entrances are narrower than the parts which accommodate the windings, and the pegging or keying pieces are arranged to lie between the windings and shoulders formed by'the slotentrances.
The object of the present invention is to provide an improved machine whereby theinsertion of deformable securing pieces (hereinafter referred to as pegging pieces) can be eifected in an expeditious manner.
The invention comprises the combination of a stationary annular headstock into which the armature can be inserted, a plurality of fingers corresponding to the number of slots in the armature and radially slidable in the headstock, means for simultaneously feeding the pegging material into the headstock at positions in line with the fingers, and finger-actuating means whereby lengths of the pegging material can be severed and transferred to the armature slots.
In the accompanying drawings:
Figure 1 is a part sectional front elevation, and Figure 2 a sectional side elevation illustrating a machine embodying the invention.
Figure 3 is a fragmentary cross sectional view of a portion of a wound armature illustrating the operation to be performed by the machine shown in Figures 1 and 2.
Referring to the drawings, there is employed an annular stationary headstock a into the center of which can be inserted at the front of the machine a previously wound radially slotted armature. In the headstock are provided a plurality of equidistantly spaced radially slidable fingers b corresponding in number to the slots in the armature. Behind the armature are mounted carriers (not shown) for coiled stocks of elongated pegging material 0, which latter may consist of paper or the like shaped to a cord or rope-like form of circular section. On an axial boss d extending from the rear side of the headstock is mounted a slidable sleeve e having therein holes through which the free ends of the material can be fed horizontally, and from which the said ends can be fed through holes in the headstock into positions adjacent to the inner ends of the fingers. On the sleeve are mounted grippers f (loaded by springs g), which when the sleeve is advanced cause the material to be moved into position, and which when the sleeve is retracted slide idly over the material. The grippers have the form of bellcrank levers which are pivoted on the sleeve e. One arm of each of these levers lies adjacent to one end of the sleeve 6, and has a serrated end which en ages the adjacent part of the materialc. When the sleeve is advanced the serrated ends of the lever arms grip the material, and when the sleeve is retracted the interaction of the material and the serrated ends of the lever arms causes the grippers to move in the direction for releasing the material.
For actuating the fingers, each has combined with it a rack h engaged by a pinion i, and all the pinions are simultaneously operable by engagement through intermediate pinions 2' with a central gear wheel 1'.
The arrangement is such that after the ends of the pegging material have been fed into position, the gear wheel 7 is moved through an appropriate angular distance by a lever m actuated by the surface n of a cam 11. The fingers are thereby caused to move inwardly for a sufficient distance to grip the pegging material, while the sleeve e of the feeding means is being retracted. Thereafter simultaneously but oppositely acting fluid operated means 0 (which may be conveniently actuated by compressed air) are brought into action for imparting further angular movement to the wheel a and thereby cause the fingers first to sever the desired lengths of pegging material from the stock. This is accomplished by inward movement of the finger b causing a cutting edge I on the said finger to co-act with a complementary cutting edge 2 formed on a ring 3 which constitutes part of the headstock a. The fingers are then caused by further inward movement to transfer the severed portions to the slots 2 in the armature 3 (Figure 3), and finally to squeeze the said portions (with simultaneous deformation of the same) into position beneath the shoulders adjacent to the slot entrances as shown in Figure 3.
As will be seen in Figure l, the wheel 7' for actuating the pinions i has associated with it three arms, one of these being the lever m above mentioned operable by the cam n, and the other two 1 being connected to the fluid operated means 0.
For automatically actuating the various movable parts of the machine, we employ a cam p for operating the axially slidable feed sleeve through a lever q (loaded by a spring or a constantly-acting compressed air means 5), the cam n for imparting the required initial movement to the lever m which actuates the fingers and also (through the surface n for returning the fingers to their initial position, and a third cam r for actuating the valve s or valves associated with the fluid-operated mechanisms 0. Also a control lever t loaded by a spring 4 is provided for actuating a clutch u associated with the driving mechanism '0, and this lever is under the control of a fourth cam w which causes the lever to release the clutch automatically at the end of each complete cycle of operations.
By means of a machine as above described the automatic pegging of armature windings can be effected in an expeditious manner. The invention is not, however, restricted to the example described, as subordinate mechanical or constructional details may be modified to suit different requirements.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
A machine for pegging or keying armature windings, comprising in combination a stationary annular headstock into which a slotted armature can be inserted, a plurality of equidistantly spaced fingers corresponding in number to the slots in the armature and radially slidable in the headstock, means for intermittently feeding elongated pegging material into positions within the headstock where parts of the material lie adjacent to the inner ends of all of the fingers, and actuating mechanism for imparting sliding movements simultaneously to all of the fingers, said REFERENCES CITED The following references are of record in the file of this patent:
