Description

Technical Field

[0001] The utility model belongs to the technical field of motor parts processing, and in particular relates to a stator wire embedding stand. Background Art

[0002] Stator wire embedding is the process of embedding the stator wire rods into the stator slots of the generator and fixing them. The automatic wire embedding machine can automatically embed the coils and wedges, and is efficient, safe and labor-saving. However, for motors that are repaired or remanufactured, the motor model is uncertain and is not suitable for mass production by the wire embedding machine. Manual wire embedding still plays an irreplaceable role. The direction of the stator needs to be flipped many times during the manual wire embedding process, but the stator has a certain weight, and it is laborious and inconvenient to manually turn or flip the stator. Secondly, the sizes of stators of different models are different. If different wire embedding stands are used for wire embedding operations, the production cost will increase. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the utility model provides a stator wire embedding stand, the purpose of which is to make the stator flippable and rotatable on the stand for the convenience of wire embedding operation, and to design an adjustable stand to adapt to stators of different diameters, which is easy to use and reduces labor intensity.

[0006] As a further optimization, a slide groove is provided on the upper surface of the turntable, and a plug is provided at the lower end of the slider, and the plug is inserted in the slide groove for sliding connection between the slider and the turntable.

[0007] As a further optimization, the lower end of the base is fixedly connected to the supporting legs, and the lower ends of the supporting legs are provided with walking wheels for making the base movable.

[0008] As a further optimization, the threaded seat is provided with a threaded through hole, one end of the screw rod passes through the threaded through hole and is fixedly connected to the crank.

[0009] As a further optimization, a rubber layer is fixedly provided on the outer surface of the support roller.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The stator can rotate vertically through a pair of support rollers and horizontally through a thrust bearing. Therefore, the stator can rotate vertically or horizontally on the stand, and the posture of the stator can be adjusted to facilitate operation by the staff.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the preferred embodiments of the present invention, rather than all the embodiments. It should be understood by those skilled in the art that these implementation methods are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-3 ;

[0022] The utility model provides the following technical scheme: a stator wire embedding stand, comprising a base 1; the upper surface of the base 1 is connected to a turntable 3 through a thrust bearing 2, so that the turntable 3 can rotate; the upper surface of the turntable 3 is slidably connected to a pair of left-right symmetrical sliders 4; a rotatable support roller 42 is provided on the upper surface of the slider 4; a screw 5 is arranged between the two support rollers 42; one end of the screw 5 is threadedly connected to a threaded seat 31 fixed on the upper surface of the turntable 3, and the other end of the screw 5 is rotatably connected to a movable block 53, the other end of the movable block 53 is hinged to a pair of support rods 51, and the other end of the support rods 51 is hinged to the side wall of the slider 4, so as to drive the pair of sliders 4 to open or close when the screw 5 rotates.

[0023] The working principle includes: a pair of support rollers 42 are supported on the lower end of the circumferential side of the stator 6 so that the stator 6 can rotate vertically, and there is no need to repeatedly move the stator 6, which saves effort; it is convenient to insert wires into the wire grooves of the stator 6 one by one. The thrust bearing 2 allows the stator 6 to rotate horizontally, which is convenient for flipping the positions of the two end faces of the stator 6 so that the operating position of the wire insertion can be as close to the operator as possible. A pair of slidable sliders 4 can adapt to stators 6 of different diameters and support the stator 6 firmly and reliably. Moreover, the screw 5 serves as an adjustment mechanism to adjust the distance between the pair of sliders 4. The screw 5 drive has the function of thread self-locking, and the pair of sliders 4 fixed in position will not shift. Among them, one end of the screw 5 is rotatably embedded in the movable block 53, such as Figure 3 As shown, when the screw rod 5 rotates, the movable block 53 does not rotate but translates along with the position of the end of the screw rod 5 .

[0024] In an exemplary sliding connection mode, a slide groove 33 is provided on the upper surface of the turntable 3, and a plug 41 is provided at the lower end of the slider 4, and the plug 41 is inserted into the slide groove 33 for sliding connection between the slider 4 and the turntable 3. Of course, the slide groove 33 can also be provided on the slider 4, and the plug 41 can be provided on the turntable 3, which can be flexibly selected according to needs.

[0025] In order to facilitate movement, the lower end of the base 1 is fixedly connected to the legs, and the lower end of the legs is provided with walking wheels for the base 1 to be movable. Thus, the stand is movable, convenient for approaching the stacked stators 6, reducing the carrying distance of the stators 6, and further saving manpower.

[0026] In order to facilitate the rotation of the screw rod 5, the threaded seat 31 is provided with a threaded through hole 32, one end of the screw rod 5 passes through the threaded through hole 32 and is fixedly connected to a crank 52. Turning the crank 52 drives the screw rod 5 to rotate, and when the screw rod 5 rotates through the threaded through hole 32, the other end of the screw rod 5 is driven to extend or retract, and then the pair of sliders 4 are driven to open or close symmetrically through the hinged support rod 51.

[0027] In order to cushion the weight of the stator 6, a rubber layer is fixed on the outer surface of the support roller 42 to reduce the damage to the stator 6 caused by collision.

[0028] The advantages of this embodiment are as follows:

[0029] (1) The stator 6 can rotate vertically through a pair of support rollers 42, and can rotate horizontally through the thrust bearing 2. Therefore, the stator 6 of this embodiment can rotate vertically or horizontally on the stand, and the posture of the stator 6 can be adjusted, which is convenient for the staff to operate.

[0030] (2) The positions of a pair of sliders 4 can be adjusted by the screw rod 5 to adapt to stators 6 of different diameters, and the adjustment is convenient.

[0031] (3) The screw rod 5 is threadedly connected to the threaded seat 31 and has a thread self-locking function. The pair of sliders 4 that have been adjusted in position will not be affected by the weight of the stator 6 and the position is fixed.

[0032] (4) The device has a simple structure, is easy to manufacture, has low cost and good versatility.

[0033] In short, the device can conveniently adjust the posture of the stator 6 and can flexibly adjust the spacing of the support rollers 42 to adapt to stators 6 of different sizes, thereby reducing the difficulty of wire embedding operation, reducing the amount of handling, and saving manpower.
