Description

Automation device of pole coil pancake winding machine

The utility model belongs to a kind of edge-wind equipment of pole coil of coil winding equipment, especially motor.

In motor pole coil manufacture process, at first be that coiling is shaped on the edge-wind equipment of special use.Existing strip on edge winding machine, as Fig. 1 and Fig. 2, its winding mechanism is by 7.5kW motor (1), through belt (2), reductor (3), and worm gear pairs (4) rotate main shaft (5), floral disc (6).For guaranteeing the lenticular wire formability, extrusion head (9) is housed.Winding former (7) is installed with the axle center symmetry, directly is fixed on the floral disc (6).Motor (1) is done rotation continuously, and during coiling, lenticular wire and extrusion head (9) all have tangible height to rise and fall.Two cylinders (10) make extrusion head (9) remain needed extruding force to lenticular wire.Before the coiling, the operator stretches out the end of a thread earlier arduously, is fixed on the floral disc (6) with wire clamp (11), could drive then.Unclamp wire clamp (11) and need stop after the coiling half-turn, the coiling of driving once more, and lean on distributor plate (8) to divide circle automatically.Because coiling center and coil center of arc do not coincide, the cydariform phenomenon of coil is fairly obvious.Because of not installing counter, need the first number number of turn after the parking again, if deficiency is arranged, again row mend around.The circulation so existing strip on edge winding machine workman in winding process must work, that is: hand is stretched line → clamping the end of a thread (driving)/() and is unclamped wire clamp (driving)/() continuous winding (parking)/() number circles (drivings)/() around half-turn (parking)/() and mend around (number circle)/() and stop.Complex operation, effort, labour intensity is big, and efficient is low, generally wants two people operation, and coil forming is of low quality, and power of motor consumption is big.

The purpose of this utility model provides a kind of automation equipment of pole coil strip on edge winding machine.Under the program command of PC, realize the Automatic Cycle of edge-wind process, that is: pneumatic connector → load onto ply-yarn drill (driving)/()

Thereby the operator is freed from the coiling cyclic process.

Overall technological scheme of the present utility model is seen Fig. 3 and Fig. 4.

Strip on edge winding machine is made up of winding mechanism and stretching mechanism.Winding mechanism comprises: motor (1), and belt (2), reductor (3), (4-8) paid in transmission, main shaft (9), floral disc (16), slide plate (15), winding former (13), cylinder (10), extrusion head (11); Stretching mechanism comprises: cylinder (21), guide post (20), linking arm (19), push rod (31).Its complex art feature is that design has the automation equipment that is distributed on each corresponding component, is embodied in: by the intermittently-driving of Geneva mechanism (4-8) realization main shaft (9), to overcome the repeatedly shortcoming of start-stop of motor; Extrusion head crossbeam (11) is gone up device land presser (17), and is in the termination that is shaped that the cydariform suppression of last wire turn is smooth.One in cover is followed dop (14) on winding former (13) bar, needn't unclamp just coiling continuously of down-lead card; Device one cover automatically controlled rest shoe (18) can be stretched out lenticular wire by the requirement of coil lead length before coiling on linking arm (19) side; Counting of main shaft (9) back-end device movable magnetic disc (7), sender meter circle automatically.

The technical scheme of this automation equipment below is described respectively, sees Fig. 3～Figure 10.

Its structure of Geneva mechanism (Fig. 5) can be integral type or setting type.Pivoted arm (5) is input as continuous transmission by reductor (3), and sheave (6) is output as intermittently and rotates.When main shaft rested, lock plate (4), locking arc (8) were located, and allow to pull out the straight flange of coil; When main shaft rotates, lay out the circular arc of coil.Coil center of arc overlaps with the coiling center, and extrusion head crossbeam (11) does not have Up-and-down, can push down lenticular wire held stationary.And existing technology is the worm gear pairs transmission, and winding former rotates around fixed center, needs repeatedly manual motor starting and stopping, braking, causes rated power obviously to increase.

Land presser on the extrusion head crossbeam (Fig. 6) is a band roller or not with the pressing plate (17) of roller, its installation site is higher than extrusion head crossbeam bottom surface 1～3mm, near 10～20mm place, coil mould distal center line inboard, be shaped and just be positioned at the centre of distributor plate (12) and line mould roller (13) when stopping at the lenticular wire of coiling, upside is concordant with the crossbeam bottom surface, last circle its cydariform of coil of coiled is high protruding in last, contact by suppression smooth with land presser (17), and slightly stretch, make circular arc and the core rod favourable minute circle that get loose.And existing technology does not have this device, by beaing with mallet around the limit on manual limit.

The dop (Fig. 8) of following on the coiling tringle is the double-vane shape, and the shelves pins (27) on empennage and the core rod offset, and prevents to rotate the ply-yarn drill of head (28) the fastening lead riser of screw (29).When driving line mould (13) rotation, floral disc (16) lays out the circular arc of coil, cylinder (21) is pulled out the straight flange of coil again when second circular arc, distributor plate (12) effect down the wire turn band of coiled that to follow dop (14) axially outer mobile along tringle together, when after the circle parking, unloading lower coil, just need pull down.And existing technology line end is to be fixed on the floral disc with chuck, need behind circular arc of coiled, stop and unload lower chuck, otherwise can not be even around with a minute circle.

The line rest shoe (Fig. 7) of stretching on the linking arm side is to be contained in support (25) upward by the fan-shaped rest shoe of magnet control, only works before each coil winding.Its rest shoe (23) is subjected to the control of electromagnet (24) and contacts lenticular wire, when cylinder (21) when promoting forward, rest shoe (23) auto lock, haul the lenticular wire feeding, during cylinder (21) backhaul, electromagnet (24) dead electricity, rest shoe (23) resets under the effect of spring (26), loosen lenticular wire, make the lenticular wire of having stretched out stay launching position.In the normal coiling cyclic process, rest shoe (23) is in relaxation state all the time, does not have the motion conflict when guaranteeing to pull out the coil straight flange.And existing technology does not have this device, firmly stretches out by the operator is manual.

The counting of rear-end of spindle device movable magnetic disc (Figure 10), go up a little magnetic steel ingot of device (30) at movable magnetic disc (7), following main shaft (9) rotates together or rests, every half cycle is sent out a signal, whenever circle and count a number (demonstration is arranged), when last circle, around intact half cycle meter 1 circle, be in same end, automatic stopping with the number of turn of assurance needs and head, the tail of lead-in wire.And existing technology is that the workman counts circle.
