Figure 1

[0026] The embodiment proposes a special adjustable jig for winding coil of electromagnetic chuck, as shown in Figure 1 and Figure 2 , which comprises mounting seat 2, front base plate 3, screw rod mechanism, rear base plate 10 and side plate 11. The rear end of mounting seat 2 is provided with a rotating shaft mounting cavity for being connected with the rotating shaft of the motor of winding machine 1. Front base plate 3 is fixed at the front end of mounting seat 2, and long circular hole one 4 is symmetrically formed at both ends of front base plate 3 along the length direction thereof. Screw rod mechanism comprises screw rod 5, nut block 6, track 12 and screw rod driving part 13, wherein screw rod 5 is arranged at the middle part of mounting seat 2 and along the length direction of front base plate 3, the threads of screw rod 5 at both sides of mounting seat 2 are opposite, screw rod 5 is rotatably connected between the middle part and mounting seat 2 through a bearing, both sides of screw rod 5 are threadedly connected with nut block 6, and the front end of nut block 6 is integrally formed with sliding seat 7 penetrating long circular hole one 4, and connecting block one 8 is fixed on sliding seat 7. Rear base plate 10 is fixed at the rear end of mounting seat 2 and is parallel to front base plate 3, and the end parts of front base plate 3 and rear base plate 10 are fixedly connected through side plate 11, the end part of screw rod 5 is rotatably connected on side plate 11 through a bearing, track 12 is installed on the surface of rear base plate 10 close to screw rod 5, and the rear end of nut block 6 is slidably connected on track 12. Screw rod driving part 13 is installed on side plate 11 for driving screw rod 5 to rotate. Screw rod driving part 13 drives screw rod 5 to rotate, the rotation of screw rod 5 makes two nut blocks 6 move synchronously towards or away from each other, thereby changing the distance between two sliding seats 7, and realizing stepless adjustment of the size of the jig.

[0027] As​Figure 3 As shown, the connecting block one 8 is provided with a long circular hole two 9 perpendicular to the long circular hole one 4, and two connecting block twos 14 are fixed on each long circular hole two 9 by bolt assemblies. The connecting block two 14 comprises a base block 1401, a reset spring 1402, a slide rod 1403 and a clamping block 1404. One end of the base block 1401 is provided with a fixing hole 1409, and the base block 1401 is fixed with the connecting block one 8 through the fixing hole 1409, the long circular hole two 9 and the bolt assembly. A rod cavity 1405 is arranged in the base block 1401, and an axle hole 1406 is provided in the other end of the base block 1401 and communicates with the rod cavity 1405. One end of the slide rod 1403 is located in the rod cavity 1405 and is provided with a limiting block 1407. The reset spring 1402 is located in the rod cavity 1405 and abuts between the limiting block 1407 and the end wall of the base block 1401 on the side of the axle hole 1406. The other end of the slide rod 1403 penetrates out of the axle hole 1406 and is fixed with the clamping block 1404, and the clamping block 1404 is used for clamping the coil support 18. The slide rod 1403 can drive the clamping block 1404 to axially stretch and retract, the limiting block 1407 is used for limiting the stretching and retracting distance of the clamping block 1404, and the reset spring 1402 is used for realizing the homing of the slide rod 1403.

[0028] The process of installing the coil support 18 on the jig is as follows: taking Figure 1 the Y direction size of the coil support 18 as an example, the Y direction position of the slide seat 7 is adjusted so that the distance between the clamping blocks 1404 on the two sides in the Y direction is slightly smaller than the Y direction size of the coil support 18; according to the Z direction size of the coil support 18, the distance between the two clamping blocks 1404 on the same side is adjusted; then the side of the coil support 18 in the Y direction is abutted on the surface of the left clamping block 1404, the right clamping block 1404 is manually pulled outward, so that the coil support 18 can enter between the two clamping blocks 1404, and finally the clamping block 1404 which is pulled outward is released, and the clamping block 1404 is reset and clamps the coil support 18 under the action of the reset spring 1402. As a preferred, a limiting hole 1408 is provided on the clamping block 1404, and the side wall of the coil support 18 can be provided with a limiting screw hole corresponding to the limiting hole 1408. When the clamping block 1404 clamps the coil support 18, a limiting screw is installed in the limiting hole 1408 and the limiting screw hole, so as to further fasten the coil support 18. As shown in Figure 4 the figure, it is a schematic view of the coil support 18 installed on the jig.

[0029] The winding machine 1 generally needs to be configured with a straightening table, and the wire 17 needs to be straightened before winding the coil. Taking Figure 1For example, since the Y direction size of the coil support 18 is adjustable, the position of the straightening table also needs to be changed accordingly. At present, the straightening table is generally a double-axis straightening table in X direction and Z direction. In order to adapt to the adjustable support of the application, the straightening table of the embodiment is selected as a three-axis straightening table in X direction, Y direction and Z direction. The adjustment in X direction and Y direction is realized through a screw rod mechanism, and the adjustment in Z direction is realized through a lifting hydraulic cylinder.

[0030] As shown in Figure 5 After the wire 17 is straightened through the straightening table, it is wound on the coil support 18. The coil support 18 is driven to rotate by the jig of the winding machine 1, so as to realize winding.

[0031] The above embodiment is only used for explaining the concept of the utility model, and is not limited to the protection of the utility model. Any non-essential change to the utility model by using the concept shall fall within the protection scope of the utility model.
