| 摘要 | A rotary coil-winding head having diametrically opposed jawmounting members mounted for movements radially of the axis of rotation of the head, and pairs of wire receiving jaw elements mounted on the jaw-mounting members for movement of the jaw elements of each pair relative to each other and to the jaw elements of the other pair for winding coils of various dimensions. | ||||||
| 权利要求 | 1. Coil-winding apparatus comprising: a. an elongated rotary head having a transverse axis of rotation centrally between its opposite ends, and defining a pair of diametrically opposed radially elongated slots; b. a pair of jaw-mounting members mounted on said head in diametrically opposed relationship for movements transversely toward and away from said axis, each of said mounting members having a radial slot aligned with an adjacent one of said radially elongated slots; c. locking means for releasably locking each of said jawmounting members in selected positions of said movement thereof; d. pairs of wire-receiving jaw elements; e. mounting means mounting each pair of said jaw elements on a different one of said jaw-mounting members for pivotal movements of the jaw elements of said pairs relative to each other and to their respective jaw-mounting members on axes parallel to the axis of rotation of said head; f. means for releasably locking said jaw elements in selected positions of said pivotal movements thereof; g. and a pair of stop elements each comprising a nut-equipped headed stop screw extending through a different one of said radially extended slots and positioned to be disposed radially outwardly of the adjacent jaw-mounting member to engage the same to limit radially outward movement thereof, and selectively to extend through said slot in the adjacent jawmounting member and clamp the same against the head radially outwardly of the adjacent one of said jaw-mounting member locking means. 2. The coil-winding apparatus defined in claim 1 in which said jaw elements of each pair thereof are independently mounted on their respective jaw-mounting members on parallel axes spaced apart circumferentially relative to the axis of rotation of said head, said jaw elements having inner end portions radially spaced from said parallel axes defining surfaces disposed in a generally common plane transversely of the axis of rotation of said head, said inner end portions including wire engaging and supporting pins extending in a common direction in radially outwardly spaced paRallel relation to the axis of rotation of the head, characterized by a generally flat wire retainer plate and means removably mounting said wire retainer plate in abutting engagement with the extended ends of said pins, said jaw element surfaces, pins and wire retainer plate cooperating to provide a wire-receiving spool. 3. The coil-winding apparatus defined in claim 1 in which said jaw elements comprise similar axially elongated jaw plates of generally right triangular outline and having axially inner generally radial base ends disposed adjacent their respective jaw-mounting members, radially inner altitude edges extending axially outwardly from said base ends, and hypotenuse portions each defining a plurality of axially spaced radially outwardly opening wire-receiving grooves having axially generally flat bottoms arranged in step formation from the base ends of their respective jaw plates to the outer ends thereof, said mounting means comprising a pair of pivot pins one each extending in a direction axially outwardly of a respective one of said jaw-mounting members, said jaw plates of each pair thereof having means on their altitude edges for pivotal mounting on one of said pivot pins whereby the jaw plates of each pair thereof are pivotally movable relative to each other and their respective mounting member on the common axis of their respective pivot pin. |
