Description
Technical field: the utility model belongs to technical field of electric mechanical equipment, is specifically related on a kind of coil expander machine for expanding the Double-conical-surface expanding trigger structure of stator end coil and slot wedge.
Background technology: in the manufacturing process of motor, three phase electric machine needs point three rules, every embedding complete phase coil needs expansion primary winding to be that rule is prepared next time, needed two coil expander machines in the past, expand the stator of an embedding good phase coil and the stator of embedding good first-phase and second-phase coil respectively, its shortcoming is that the manufacturing cost of two equipment is higher, and production efficiency is low, adds the production cost of enterprise and user.
Summary of the invention: the purpose of this utility model is to provide that a kind of structure is simple, easy to adjust, the Double-conical-surface expanding trigger structure of reliable in action, can complete the stator of expansion one phase coil and the stator of expansion two phase coils respectively on an equipment.
The technical solution of the utility model is: a kind of Double-conical-surface expanding trigger structure, it is characterized in that: on shaping core, be laid with some grooves expanding plate is installed, shaping core upper end is connected by the first holding screw and positioning disk, and shaping core lower end is connected with a point the end of a thread by the second holding screw; Bottom end cover is provided with in the cavity that shaping core and point the end of a thread are formed, bottom end cover is connected by the first screw and shaping core, slide in the cap bore of lower end and be provided with lower guide rod, lower guide rod lower end and lower connecting block are connected by the second screw, lower guide rod upper end is connected with lower compacting ring, is provided with lower stage clip between compacting ring and bottom end cover down; Slide in the disk hole of location and be provided with top guide bar, top guide bar upper end is connected by the 3rd screw and upper contiguous block, top guide bar lower end is connected with upper compacting ring, compression spring is provided with in the cavity that positioning disk and upper compacting ring are formed, the chamber central formed at positioning disk and shaping core and point the end of a thread is slidably fitted with mandrel, mandrel lower end is provided with three tapered sleeves and three fixed covers pass through fastening nuts, mandrel upper end passes from upper compression collar aperture, the fixed cover of mandrel lower end passes from lower compacting ring hole, and mandrel lower end passes from bottom end cover and lower connecting block hole; The conical surface of upper compacting ring lower end is positioned at the skewed slot of expanding plate upper end, and the conical surface of lower compacting ring upper end is positioned at the skewed slot of expanding plate lower end.
Owing to have employed technique scheme, it is all with the conical surface by tapered sleeve two ends, when mandrel drives tapered sleeve to move downward, the conical surface and part expanding plate contact of incline plane under tapered sleeve, thus drive expanding plate to expand outwardly first-phase coil, when mandrel drives tapered sleeve to move upward, the conical surface and another part expanding plate contact of incline plane on tapered sleeve, expanding plate is driven to expand outwardly second-phase coil, thus reach the object can expanding first-phase and second-phase coil respectively, have easy to adjust, reliable in action, shaping effect is good, an equipment can complete the stator of expansion one phase coil and the stator of expansion two phase coils respectively, improve the advantage of production efficiency.
Accompanying drawing illustrates: be described in further details the technical solution of the utility model below in conjunction with the drawings and specific embodiments.Fig. 1 is structural representation of the present utility model.Fig. 2 is the plan view of Fig. 1.
