In the description of the present application, term " first ", " second " etc. are used for description purposes only, and should not be understood as instruction or It implies relative importance or implicitly indicates the quantity of indicated technical characteristic.

The utility model discloses a kind of three needle coil winding machines, use three enameled wires simultaneously, each enameled wire is respectively Coiling is carried out to a stator poles, improves the production efficiency of stator.The three needle coil winding machines of the utility model, line mouth are not being sent out Raw circumferential direction movement and realize three needles and around, prevented because coiling nozzle because occur circumferencial direction it is mobile caused by enameled wire it is mutual The phenomenon that tangle up.

The three needle coil winding machines of the utility model include rack 1, main shaft 2, enameled wire for line mechanism 3, workpiece jig 4, three needles It coiling nose assembly 5, openable and closable wire-clamping device 6, workpiece quick assembling mechanism 7, tension decay mechanism 8, hook line cover pressing mechanism 9 and cuts Line mechanism 10, hook line mechanism 11.

Main shaft 2 is located in rack 1, and main shaft 2 is installed for workpiece jig 4, if main shaft 2 has a point during circumferentially rotating Degree, and main shaft 2 presses the intermittent reciprocating rotation of scheduled angle in each indexing position.As shown in Figure 3, main shaft 2 includes Shaft 201, shaft 201 are mounted on bearing block 203 by bearing 202.Specifically, shaft 201 and the inner ring of bearing 202 are nested It connects, the inner ring of bearing is locked by nut 207, and nut is threadedly coupled with shaft 201.The outer snare of bearing 202 is in bearing block In 203, the outer ring of bearing 202 is fixed in bearing block 203 by the lock ring 204 being fixed on bearing block 203.Bearing block 203 with Workbench 101 is fixedly connected.Workbench 101 is fixed in rack 1 by horizontal.Shaft 201 passes through shaft coupling 205 and motor 206 output shaft is connected.In the present embodiment, motor 206 uses servo motor.Servo motor is turned by driving device control It is dynamic.In one embodiment, three needle coil winding machines are used to carry out coiling, servo motor to the workpiece 100 with 12 stator poles 100a Drive mode are as follows: main shaft 2 rotation circumferentially rotate during (i.e. all stator poles are by three needlework around machine coiling enameled wire Period) there are four indexing for tool, and servo motor needs servo electric after completing one group of (three stator poles) stator poles coiling as a result, Machine control main shaft 2 turns over 90 degree and carries out coiling to next group of stator poles (three stator poles).Main shaft 2 each indexing position with The intermittent reciprocating rotation of 30 degree of angle, at work, interval after main shaft 2 rotates 30 degree clockwise, to three needle machines After head assembly completes predetermined action, interval after main shaft 2 rotates 30 degree counterclockwise, then complete to make a reservation for three needle nose assemblies Movement, recycles repeatedly, until main shaft 2 turns over 90 degree, makes after one group of stator poles is wound by enameled wire by scheduled the number of turns Next group of stator poles of workpiece are turned to winding position and receive coiling.It should be pointed out that make next group of stator poles quilt It turns to winding position and receives coiling, main shaft 2 can also be realized by other rotational angles, such as complete to turn over 270 in advance The stator poles winding operation of degree and 180 degree orientation finally completes remaining one group of stator poles again.

It should be pointed out that the quantity of indexing of the main shaft 2 during circumferentially rotating is the stator according to the workpiece to coiling Depending on number of poles, such as workpiece has 24 stator poles then main shaft 2 has 8 indexing, and the angle of corresponding reciprocating rotation is 15 Degree.

Workpiece jig 4 is connected with main shaft 2 and attaches the main shaft 2 and rotate synchronously.In the present embodiment, workpiece Jig 4 is fixed on main shaft 2.Referring to Fig. 3, Figure 16, workpiece jig 4, there is the main body 401 for being substantially cylindrical in shape structure, It is placed into for workpiece in axis direction.Step 402 is equipped in main body inner wall, for the week edge overlap joint of workpiece, to make workpiece It is embedded into workpiece jig 4 and is supported on workpiece jig 4.In the present embodiment, step 402 is circumferentially continuous, as another Embodiment, step can be discrete, have and several segments and are distributed in the circumferential.In general, being set on the inner wall of workpiece jig There is fin, to limit and anti-misloading to workpiece with circumferential.

In general, as shown in Figure 3, workpiece 100 has part to be exposed at outside workpiece jig 4, make workpiece quick assembling mechanism 7 to work whereby Part 100 is fixed, and locks workpiece and unlock so as to automatically control workpiece quick assembling mechanism 7.

In one embodiment, referring to Fig. 3, workpiece quick assembling mechanism 7 includes pressing plate 701, and pressing plate has body portion 7011 and top 7012.Top 7012 is fixedly connected with the one end in body portion 7011, and the extending laterally and be used for from body portion 7011 of top 7012 Workpiece is axially withheld, the two constructs the shape substantially in 7 shapes.Body portion 7011 is hinged with workpiece jig 4, as shown in, body Portion and the lateral wall of workpiece jig are hinged, in this way, providing the reaction force on axis direction to workpiece in pressing plate and withholding When workpiece, pressing plate using its hinged intensity with workpiece jig without only relying on the restoring force of spring, thus enable workpiece by It is firmly loaded on workpiece jig.Top 7012 is set to withhold work status in axial by the first spring (not showing on figure). First spring is pressure spring structure, and one end offsets with body portion 7011, and the other end offsets with workpiece jig 4.In general, in body portion 7011 It is assembled with 702 structure of counter sink is respectively provided on workpiece jig 4 for pressure spring.The output end of second straight line reciprocating mechanism 703 With the first position separated with 7011 phase of body portion and compressing body portion 7011 tilts top 7012 and in releasing axial button Press the second position of work status.The output end of second straight line reciprocating mechanism 703, which is often in, to be separated with 7011 phase of body portion State, as a result, during workpiece jig 4 rotates, the output end of second straight line reciprocating mechanism 703 does not interfere workpiece to be controlled 4 rotation of tool.When needing to pick and place workpiece, second straight line reciprocating mechanism 703 works, and output end stretches out and is pressed on body portion 7011, while pressure spring is compressed, top 7012 tilts and mutually separates with workpiece, withholds workpiece to release.It should be pointed out that Height and position after tilting should not interfere the pick-and-place of workpiece.

At work, the output end of second straight line reciprocating mechanism 703 does not connect workpiece quick assembling mechanism 7 with body portion 7011 Touching makes top 7012 in the axial state for withholding workpiece using pressure spring, and in specific application, top 7012 connects with workpiece Touching is to withhold workpiece, so that workpiece is firmly installed on workpiece jig 4.When being intended to remove workpiece, second straight line is past The output end of multiple movement mechanism 703 stretches out, and compresses body portion 7011, overcomes the resistance of pressure spring, finally make top 7012 tilt and with Workpiece is separated.

In the present embodiment, second straight line reciprocating mechanism uses cylinder, is fixed on workbench 101.
