Abstract

The utility model relates to a side-by-side double-headed stator coil lead wire riser positioning elbow tool, belonging to the manufacturing tool field of the motor stator coil, which solves the problem of that the existing side-by-side double-headed stator coil lead wire riser lineation elbow tool can't meet the requirements of mass production, has the large volume, the heavy weight and the time-wasting and labor-wasting operation, and is inconvenient to be carried and moved. The elbow tool is composed of a connecting plate, a left elbow die and a right elbow die, wherein the connecting plate is consistent with the size and shape of the nose part of the stator coil, and the left elbow die and the right elbow die have the same structure and symmetrically fixed on the two ends of the connecting plate; the elbow die is composed of an elbow die body, an elbow die cover and a positioning block fixed on the bottom of the elbow die body and opened with a positioning groove, wherein the positioning block is fixed on the connecting plate. The elbow tool has the simple structure, the small volume, the convenient operation and the time-saving and labor-saving operation, bends into one stator coil in ten minutes, and can complete the elbow procedure by one person. The utility model has the consistent positioning size, meets the technical requirements of the mass production, and solves the process difficulty.

Description

Double-head stator coil lead head is located the elbow frock side by side

Technical field

The utility model relates to the manufacturing frock of coil of stator of motor, is specially double-head stator coil lead head location elbow frock side by side.

Background technology

On the YJ85A motor of introducing, stator coil adopts double-head stator coil side by side.During the YJ85A motor was introduced trial-production, double-head stator coil lead head bent no special-purpose elbow equipment side by side, the lead riser that bends must before and after to overlap be one, the lead riser bulk after bending can't guarantee the consistency produced in batches to become critical technological point.The processing step that present double-head stator coil lead head side by side bends is: stator coil is after expanding machine has risen by type: the first step: stator coil is placed on the centering work of the enterprising line lead head of the lead spacing model left and right sides, needs two operators to carry out simultaneously.Second step: after the stator coil centering, utilize Steel Ruler to carry out the line work of lead riser elbow position again.The 3rd step: after having drawn line, utilize curved wire holder to carry out elbow in the position of line.Curved 1 stator coil in per 40 minutes.The consistency of the stator coil lead riser of this frock processing is poor, can not satisfy the needs of batch process, and lead spacing model volume is big, Heavy Weight, be not easy to carry and move, and operation is wasted time and energy.

Summary of the invention

The utility model is in order to solve big, the Heavy Weight of needs, volume that the existing coil lead of double-head stator side by side head line elbow frock can not satisfy batch process, be not easy to carry and move and operate problem such as waste time and energy, a kind of coil lead of double-head stator side by side head location elbow frock of new structure is provided.

The utility model is to adopt following technical scheme to realize: double-head stator coil lead head is located the elbow frock side by side, by with the connecting plate of stator coil nose size shape unanimity be symmetrically fixed on the identical left elbow mould of structure at connecting plate two ends, right elbow mould is formed, (left side, right) the elbow mould comprises and has the curved die body that two lead risers compress the inclined-plane on it side by side, have on it with curved die body on the curved die cap that compresses the clamping plane that the inclined-plane cooperates and be fixed in curved die body bottom, have the locating piece of detent on it, have the dowel hole of position correspondence on curved die body and the curved die cap, be placed with alignment pin in the dowel hole, locating piece and connecting plate are fixed and (thereby are realized a left side, fixing of right elbow mould and connecting plate).

Location described in the utility model elbow tool structure is simple, volume is small and exquisite, be convenient to operation, need not rule, and one-time positioning will be bent die cap and cover on curved die body on stator coil, utilize sleeve pipe to carry out elbow, once finish the elbow operation.Curve 1 stator coil in 10 minutes, and a people just can finish the elbow operation, it is time saving and energy saving to operate.The location dimension unanimity, the consistency of assurance stator coil lead riser that can be effectively satisfies the specification requirement of producing in batches, has solved critical technological point.Make the line behind the stator coil rule, obtained effective guarantee.

Embodiment

Double-head stator coil lead head is located the elbow frock side by side, by with the connecting plate 1 of stator coil nose size shape unanimity be symmetrically fixed on the identical left elbow mould of structure at connecting plate two ends, right elbow mould is formed, (left side, right) the elbow mould comprises and has two lead risers on it side by side and compress inclined-plane 2,3 curved die body 4, have on it with curved die body on compress the clamping plane 5 that the inclined-plane cooperates, 6 curved die cap 7 is bent the die body bottom with being fixed in, have the locating piece 9 of detent 8 on it, have the dowel hole 10 of position correspondence on curved die body 4 and the curved die cap 7, be placed with alignment pin 11 in the dowel hole, locating piece 9 is fixing with connecting plate 1.During use, the stator coil that the moulding sanding is intact lies on the platform, and lead riser separates to both sides; The connecting plate 1 of elbow frock is aimed at the nose of stator coil, simultaneously the detent on the locating piece of left and right elbow mould 8 is stuck on the stator coil, open curved die cap 7, place two lead risers of curved die body to compress on the inclined-plane 2,3 lead riser side by side of stator coil, cover curved die cap and push down lead riser, prevent lead riser left and right sides play, simultaneously alignment pin 11 is inserted in the dowel hole of curved die body and curved die cap.The alignment pin 11 main positioning actions that rise between curved die body and the curved die cap prevent curved die cap front and back play.The operator is inserted in separately the lead riser with a sleeve pipe, utilize sleeve pipe up and down two lead-in wires outwards be bent to the position successively, bend one side, bend another side.Take out location elbow mould, finish the elbow work of a coil.
