Abstract
The utility model discloses a kind of air core coil and close semicircle shaped device, comprise footstalk, mandrel and spindle positioning device, described footstalk one end is provided with an axial socket, mandrel one end is inserted in this slot, spindle positioning device can keep mandrel and footstalk stationary positioned, mandrel other end end face is provided with the indent draw-in groove that passes axle center, be able to accommodating single line material in this draw-in groove, the utility model is by arranging an indent draw-in groove by axial line in the end of mandrel, indent draw-in groove and wire diameter coupling, coiling program is changed into top-down mode by original mode from bottom to top, thus ensure that the semicircle of the semicircle closure of coil has the uniformity of height, production switch debug time shortens greatly, efficiency improves nearly 100%, yield can remain on more than 98%.
Description
Technical field
The utility model relates to a kind of air core coil shaped device, and particularly a kind of air core coil closes semicircle shaped device.
Background technology
Conventional winding method carrys out card line by the cable clamping interface mouth 7 between mandrel and footstalk, after material winds terminates, randomly or the semicircle of the extruded blind end of cutter.The low peeling change in size that causes of semi-circular shape uniformity is comparatively large, and fraction defective is higher, and production efficiency is not high, and coordinate loop length to debug by adjustment mandrel extension elongation more difficult, production switch debug time length, efficiency is low, and fraction defective is high.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of air core coil and closes semicircle shaped device structure, and it is simple that this air core coil closes semicircle shaped device structure structure, can realize air core coil two ends and automatically form semicircle closing in, ensure that the uniformity of coil semicircle, threading speed is fast.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of air core coil closes semicircle shaped device, comprise footstalk, mandrel and spindle positioning device, described footstalk one end is provided with an axial socket, mandrel one end is inserted in this slot, spindle positioning device can keep mandrel and footstalk stationary positioned, mandrel other end end face is provided with the indent draw-in groove that passes axle center, be able to accommodating single line material in this draw-in groove.
As further improvement of the utility model, described spindle positioning device is at least one puller bolt, footstalk sidewall is provided with at least one radial bolts hole, puller bolt is bolted in this bolt hole, and puller bolt stud end can stretch into footstalk axial socket in and be closely against on axle periphery wall.
The beneficial effects of the utility model are: the utility model is by arranging an indent draw-in groove by axial line in the end of mandrel, indent draw-in groove and wire diameter coupling, coiling program is changed into top-down mode by original mode from bottom to top, thus ensure that the semicircle of the semicircle closure of coil has the uniformity of height, production switch debug time shortens greatly, efficiency improves nearly 100%, and yield can remain on more than 98%.

Fig. 2 is the structural principle schematic diagram of prior art.
Detailed description of the invention
Embodiment: a kind of air core coil closes semicircle shaped device, comprise footstalk 1, mandrel 2 and spindle positioning device, described footstalk 1 one end is provided with an axial socket 3, mandrel 2 one end is inserted in this slot, spindle positioning device can keep mandrel 2 and footstalk 1 stationary positioned, mandrel 2 other end end face is provided with the indent draw-in groove 4 that passes axle center, be able to accommodating single line material in this draw-in groove, during coiling, wire rod is stuck in the indent draw-in groove 4 of mandrel 2 other end, then footstalk 1 and mandrel 2 together rotate, wire rod by from bottom to top around on mandrel 2, stop being wound around when it is around the cable clamping interface mouth position formed to mandrel 2 and footstalk 1, wire rod two ends are subject to the constraint of indent draw-in groove 4 and cable clamping interface mouth, the air core coil two ends formed form semicircle closing in automatically, this kind of structure makes the closed semicircle closing-in structure size of air core coil accurate, profile is consistent, threading speed is fast.
Described spindle positioning device is at least one puller bolt 5, footstalk 1 sidewall is provided with at least one radial bolts hole 6, puller bolt 5 is bolted in this bolt hole, and puller bolt 5 stud end can stretch into footstalk 1 axial socket 3 in and be closely against on axle periphery wall.
