Description

Technical Field

[0002] The repair of motor burnout requires winding. Traditional motor winding uses wooden molds in conjunction with winding machines. In the process of winding with wooden molds, only one pole-phase winding can be wound at a time. After winding one pole-phase winding, the wooden mold needs to be removed, the wound winding removed, and then assembled to wind the next pole-phase winding. The use of wooden molds in the winding process of a motor requires multiple disassembly and assembly of the mold. There are many motor models, and the corresponding winding sizes are different, so a huge number of wooden molds are required, and the winding operation is time-consuming and labor-intensive, which seriously reduces the operating efficiency. Summary of the invention

The two transverse straight rods are respectively perpendicularly arranged on the end faces of the two transverse sliders and follow the two transverse sliders to move transversely along the transverse rails. The two longitudinal rails are respectively movably arranged on the transverse rails at intervals and are located on the inner sides of the two transverse sliders. The four longitudinal sliders are respectively arranged on the two longitudinal rails and are positioned by fixing bolts. The four longitudinal straight rods are respectively perpendicularly arranged on the end faces of the four longitudinal sliders and follow the four longitudinal sliders to move longitudinally along the two longitudinal rails.

[0005] Furthermore, the tooling also includes nylon separation rings, which are respectively inserted into the two transverse straight rods and the four longitudinal straight rods and are arranged at intervals along the length direction.

[0006] Furthermore, the tooling also includes a span support plate, which is provided with a long waist hole along the length direction, and the free ends of the two transverse straight rods are inserted into the long waist hole of the span support plate and fixed by nuts.

[0007] Furthermore, the tooling also includes four diagonal braces, one end of each of which is respectively connected to the free ends of the four longitudinally movable straight rods, and the other end of each of which is connected to the span support plate.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0012] Figure 3 for Figure 1 Top view of the . DETAILED DESCRIPTION

[0013] Implementation example Figure 1 , Figure 2 and Figure 3 As shown, the utility model for the winding tooling of the low-voltage motor winding comprises a transverse rail 1, two transverse sliders 2, two transverse straight rods 3, two longitudinal rails 4, four longitudinal sliders 5 and four longitudinal straight rods 6, the transverse rail 1 is centrally provided with a connecting hole 11, the two transverse sliders 2 are arranged on the transverse rail 1 and are positioned by fixing bolts 12, the two transverse straight rods 3 are respectively perpendicularly arranged on the end faces of the two transverse sliders 2 and follow the two transverse sliders 2 to move transversely along the transverse rail 1, the two longitudinal rails 4 are respectively movably arranged on the transverse rail 1 at intervals and are located on the inner sides of the two transverse sliders 2, the four longitudinal sliders 5 are respectively arranged on the two longitudinal rails 4 and are positioned by fixing bolts 13, and the four longitudinal straight rods 6 are respectively perpendicularly arranged on the end faces of the four longitudinal sliders 5 and follow the four longitudinal sliders 5 to move longitudinally along the two longitudinal rails 4.

[0014] Preferably, the tool further comprises nylon separation rings 7, which are respectively inserted into the two transverse straight rods 3 and the four longitudinal straight rods 6 and are arranged at intervals along the length direction.

[0015] The nylon separation ring can separate the wound multiple windings, so that the tooling has the function of winding multiple pole-phase windings at the same time.

[0016] Preferably, the tooling also includes a span support plate 8 , which is provided with a long waist hole along the length direction, and the free ends of the two transverse straight rods 3 are inserted into the long waist hole of the span support plate 8 and fixed by nuts 14 .

[0017] Preferably, the tooling further includes four diagonal braces 9 , one end of each of which is respectively connected to the free ends of the four longitudinally movable straight rods 6 , and the other end of each of which is connected to the span support plate 8 .

[0018] During the winding process, the winding will exert a large force on the two transverse straight rods and the four longitudinal straight rods, which are prone to deformation at the free ends, resulting in size deviation of the wound winding. This tool connects the free ends of the two transverse straight rods through a span support plate to limit the spacing between the free ends of the two transverse straight rods, connects the free ends of the four longitudinal straight rods and the span support plate through four diagonal braces to limit the spacing between the free ends of the four longitudinal straight rods, thereby avoiding deformation, making the dimensions on both sides consistent, and ensuring that the winding size meets the standard.

[0019] When winding low-voltage motor windings, the transverse rail is connected to the rotating shaft of the winding machine through the centrally arranged connection hole, and the spacing between the two transverse sliders and the two transverse straight rods, as well as the spacing between the two longitudinal rails on the transverse rails, and the spacing between the four longitudinal sliders and the four longitudinal straight rods on the two longitudinal rails are adjusted according to the size of the winding. The two transverse straight rods and the four longitudinal straight rods form a winding frame for winding the winding. Then, one end of the winding is pressed and fixed on the winding frame with bolts, and the winding machine is started to drive the winding frame to rotate, so that the winding is wound around the winding frame one circle at a time to form the motor winding.

[0020] The transverse slider and the longitudinal slider in this tooling realize the adjustment function of the winding frame. The spacing between the two transverse straight rods, the two longitudinal rails and the four longitudinal straight rods can be adjusted according to different winding sizes to meet the needs of winding motors of different models. At the same time, the side of the transverse rail and the two longitudinal rails is provided with a ruler scale, and the spacing between the two transverse straight rods, the two longitudinal rails and the four longitudinal straight rods can be quickly adjusted according to the ruler scale to the winding size required for winding.

[0021] This tooling can effectively reduce the winding time, save winding costs, and improve winding efficiency. A set of winding frames can be used to wind all types of motor windings without changing the winding mold. At the same time, this tooling can adjust the size of the winding frame. When replacing the pole phase winding, there is no need to remove the winding mold. The wound winding can be directly removed and the next winding can be wound. The motor winding winding time is saved by 4 hours / unit, and the number of operators is optimized to 1 person. Compared with the use of wooden molds, the cost of winding is reduced by 2,000 yuan / unit, and the motor repair time is saved by 4 days / unit.
