Description

Technical Field

[0001] This utility model belongs to the field of stator production welding and shaping technology, and relates to an Xpin stator pre-welding shaping equipment. Background Technology

[0002] Flat wire motors are currently the mainstream motor winding method. Compared to round wire, flat wire is beneficial for improving the slot fill factor. Generally, the slot fill factor of a round wire motor is around 50%, while that of a flat wire motor can reach over 70%. This increased slot fill factor means that, with the stator slot space remaining constant, more copper wire can be filled, allowing for a larger current to flow and generating a stronger magnetic field, thereby increasing power density. Xpin is one type of winding method for flat wire motors. Because X-pin stators have high requirements for the welding surface during welding, and also have high precision requirements for the height and distance of the coil group output wires; however, due to the limitations of existing assembly processes, meeting the assembly requirements of X-pin stators has always been a difficult problem to solve in the industry. Therefore, it is necessary to shape the stator copper wires before welding to improve the subsequent welding quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figures 1 to 5 The specific embodiments of this utility model will be described in further detail.

[0024] Depend on Figures 1 to 5 As shown, in order to achieve a better copper wire clamping effect, this utility model includes a workbench 1. The upper side of the workbench 1 is provided with a lifting and rotating part 2 for longitudinally lifting and horizontally rotating the stator. The upper side of the workbench 1 is provided with a shaping part 34 for straightening and shaping the copper wire. The shaping part 34 includes an adjustment plate 3 that can be raised and lowered relative to the workbench 1. The adjustment plate 3 is provided with a plurality of straightening components 4 and an adjustment component that corresponds one-to-one with the straightening components 4. Each correction component 4 includes a pressure bar 6 and two clamps 7 that can approach each other. The two clamps 7 are respectively located on both sides of the pressure bar 6, and the two clamps 7 approach each other to form a copper wire clamping structure. It should be noted that the lifting and rotating part 2 is existing technology, including a cylinder, an intermediate plate, a servo motor, a rotating plate, and a positioning seat. Specifically, its specific structure is the same as the lifting and rotating assembly in Chinese invention patent with publication number CN119245472A. Both can drive the intermediate plate to move up and down through the cylinder and simultaneously drive the servo motor to move, thereby adjusting the height position of the stator to be welded in the vertical direction. In addition, when the servo motor drives the rotating plate to rotate, it simultaneously drives the positioning seat to rotate, thereby causing the stator to be welded to rotate, so that the copper wire can be straightened by the straightening assembly 4 at all angles of the top of the stator to be welded. Furthermore, by Figures 1 to 5 As shown, in order to facilitate the transport of the stator, a conveyor 8 for transporting the stator is provided on the upper side of the workbench 1. It should be noted that the line body 8 is set on the workbench 1 to transport the stator in the workflow and to facilitate the transport of the shaped stator for subsequent welding processing. In use, the Xpin stator flows along the wire body 8 to directly below the shaping section 34. The lifting and rotating section 2 first lifts the stator, and the adjusting plate 3 drives multiple straightening components 4 to move down together, so that the straightening components 4 can straighten the copper wires at the end of the Xpin. By setting multiple sets of straightening components 4, multiple sets of copper wire pairs can be straightened at one time. Then the lifting and rotating section 2 drives the stator to rotate to complete the straightening and shaping of all copper wires.

[0025] Furthermore, by Figures 1 to 5 As shown, to increase the accuracy of the device during operation, the shaping unit 34 further includes: A support frame 9 is fixedly connected to the upper side of the workbench 1, and a mounting plate 10 is fixedly connected to the upper side of the support frame 9; A transition plate 11 is set on the lower side of the mounting plate 10. Three mounting columns 12 arranged in a ring array are detachably connected to the lower side of the transition plate 11 by bolts. An adjustment plate 3 is set on the lower side of the transition plate 11, and the lower side of each mounting column 12 is detachably connected to the adjustment plate 3 by bolts. An electric cylinder 13 is fixedly connected to the upper side of the mounting plate 10. The output end of the electric cylinder 13 passes downward through the mounting plate 10 and is fixedly connected to the upper end of the transition plate 11. Four rectangular guide posts 14 are slidably connected through the mounting plate 10. The lower end of each guide post 14 is fixedly connected to the upper end of the transition plate 11. The electric cylinder 13 is an electric push rod, and the output is linear motion, which will not be described in detail here. In use, the electric cylinder 13 pushes the transition plate 11 to move up and down, which, together with the straightening component 4, can straighten and shape the stator copper wire. During the up and down movement, the guide post 14 makes the up and down movement of the transition plate 11 smoother and increases the vertical accuracy. The mounting post 12 makes it possible to leave a distance between the transition plate 11 and the adjustment plate 3 to facilitate the installation of the straightening component 4 and to facilitate the disassembly and maintenance of the components.

[0026] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the positioning of the stator and reduce damage to the stator, the lower side of the adjustment plate 3 is provided with multiple top posts 15, and the lower end of the adjustment plate 3 is fixedly connected with multiple mounting blocks 16 distributed in a ring array. The mounting blocks 16 are all slidably fitted on the outside of the corresponding top posts 15. A pad 17 is fixedly fitted in the middle of the top post 15, and a spring 18 is provided between the pad 17 and the mounting block 16. During use, as the adjusting plate is pressed down, the lower end of the top column 15 will press against the stator end face to initially position the stator. At this time, the buffer spring 18 can buffer the pressure of the top column 15 on the stator end face to a certain extent, so as to reduce the risk of damaging the stator end face.

[0027] Furthermore, by Figures 1 to 5 As shown, in order to be compatible with stators of different sizes, the correction assembly 4 includes: The motor mounting base 19 and the bearing housing 20 are respectively set on the upper and lower sides of the adjustment plate 3. The adjustment plate 3 is provided with a strip groove 21 and a through groove 22. The motor mounting base 19 and the bearing housing 20 are connected through the strip groove 21 and the through groove 22. The first rotating column 35 is rotatably connected to the lower side of the bearing housing 20, and a second rotating column 23 is provided on the lower side of the first rotating column 35. A first fixing block 24 is provided on the lower side of the second rotating column 23; The cylinder 25 is installed inside the second rotating column 23. The output end of the cylinder 25 extends downward to the lower side of the second rotating column 23 and is fixedly connected to the first fixing block 24. It should be noted that the motor mounting base 19 and the bearing housing 20 are fastened together by the through groove 22. Specifically, when installing between the motor mounting base 19 and the bearing housing 20, a bolt can be used to pass through the bottom of the bearing housing 20. The middle part of the bolt passes through the through groove 22 and is threadedly connected to the threaded groove at the bottom of the motor mounting base 19, so that the servo motor 32 and the bearing housing 20 can slide back and forth along the direction of the strip groove 21. In use, by setting the through slot 22, the position of the motor mounting base 19 relative to the adjustment plate 3 can be adjusted more conveniently. By setting the strip slot 21, the rotational power of the first rotating column 35 can be transmitted conveniently, thereby driving the second rotating column 23 to rotate.

[0028] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the clamping of copper wires, a support block 26 is fixedly connected to the front and rear sides of the lower end of the second rotating column 23. The middle part of each clamp 7 is rotatably connected to the support block 26, and the upper end of each clamp 7 is rotatably connected to a connecting rod 27. The end of each connecting rod 27 away from the clamp 7 is rotatably connected to the first fixed block 24. Furthermore, by Figures 1 to 5 As shown, in order to facilitate the twisting action of the copper wire, a servo motor 32 is fixedly connected to the upper side of the motor mounting base 19, and the output end of the servo motor 32 extends downward and is fixedly connected to the first rotating column 35. In use, by rotating the middle part of the clamp 7 to the support block 26, the lower ends of the two clamps 7 can move closer and further apart more easily, thus facilitating the clamping of copper wire; the upper end of the pressure strip 6 is fixedly connected to the first fixing block 24. During the clamping action, the cylinder 25 pushes down the first fixing block 24, and the connecting rod 27 pushes the clamp 7 to deflect, so that the lower ends of the two clamps 7 move closer to each other. At the same time, the pressure bar 6 also moves down, the clamps 7 clamp the copper wire, and the pressure bar 6 presses against the top flat end of the copper wire pair. The output end of the servo motor 32 drives the first rotating column 35 to rotate, and then drives the copper wire to rotate through the second rotating column 23 and the clamps 7, so that the copper wire pair is twisted to a certain extent, making the copper wire pair more tightly attached to ensure the welding quality.

[0029] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the connection of cylinder 25, a connector 28 for connecting cylinder 25 is provided on the outer side of the first rotating column 35, and the first rotating column 35 and the second rotating column 23 are connected by bolts. When in use, the cylinder 25 can be connected to the air source and control cable through connector 28.

[0030] Furthermore, by Figures 1 to 5 As shown, in order to facilitate precise adjustment of the position of the correction component 4, the adjustment component includes a second fixing block 29 bolted to the adjustment plate 3. An adjustment connecting block 30 is fixedly connected to the side of the motor mounting base 19 near the second fixing block 29. An adjustment bolt 31 is rotatably connected to the upper side of the second fixing block 29. The end of the adjustment bolt 31 near the adjustment connecting block 30 is threaded to the adjustment connecting block 30. The adjustment plate 3 is provided with adjustment scales for observing the position of the motor mounting base 19. It should be noted that by connecting the second fixing block 29 to the adjusting plate 3 with bolts, the position of the second fixing block 29 can be adjusted more conveniently during use. Specifically, after the position of the second fixing block 29 is fixed, the position of the motor fixing seat 19 can be adjusted by rotating the adjusting bolt 31 and the threaded connection between the adjusting bolt 31 and the adjusting connecting block 30.

[0031] When this utility model is in use, the Xpin stator moves along the wire body 8 to directly below the shaping part 34. The lifting and rotating part 2 first lifts the stator, and the adjusting plate 3 drives multiple straightening components 4 to move down together, so that the straightening components 4 can straighten the copper wires at the end of the Xpin. By setting multiple sets of straightening components 4, multiple sets of copper wire pairs can be straightened at one time. Then the lifting and rotating part 2 drives the stator to rotate to complete the straightening and shaping of all copper wires.

[0032] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, a better copper wire clamping effect is achieved, which facilitates the transport of the stator, increases the accuracy of the device during operation, facilitates the positioning of the stator and reduces damage to the stator, makes the copper wire pairs fit more tightly, and ensures the welding quality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
