Description

Technical Field

[0001] The present invention belongs to the technical field of copper wire forming equipment, and specifically relates to a wave winding 3D pre-forming equipment.

Background Art

[0002] The stator wave winding 3D forming technology is a revolutionary innovation in the motor manufacturing field. By adopting the wave winding and 3D forming process, not only has the performance of the motor been greatly improved, but it has also promoted the development of the automation and smartness of motor manufacturing. As the technology is being developed, this technology will play a greater role in technical fields such as new energy vehicles, aerospace, and renewable energy, and will surely provide solid technical support for the research and development of high-efficiency energy-saving equipment.

[0003] For a specific stator design (such as windings outside the slots or a stator with a special shape), the wave winding 3D forming adopts a method of forming using a 2D wave winding and then performing 3D assembly and processing to realize the 3D forming process of the wave winding.

[0004] Conventional 3D press forming equipment performs the process of directly press forming on the wave winding in a 2D state. The wire in a 2D state is loose and easy to deform. If directly used for forming, the winding shape will become uncontrollable, affecting the motor performance. Also, when directly performing 3D pressing on the 2D formed wave winding, scattering and displacement of the winding may occur.

[0005] Therefore, how to ensure the stability of the overall structure of the wave winding after 2D forming when performing 3D pressing, and how to facilitate 3D press forming are necessary problems.

[0024] The pre-winding means 4 includes a circular type I 44 and a circular type II 45, a plurality of copper wire hook assemblies 41 mounted between the circular type I 44 and the circular type II 45 for securing the corrugated copper wire, a plurality of copper wire pressing assemblies 42 mounted on the same side of the plurality of circular types II 45 for limiting the corrugated copper wire, and a drive assembly 43 mounted on the same side of the circular type I 44, wherein the circular type I 44 and the circular type II 45 are fitted onto both ends of the rotating shaft 46 via fixed circular connecting members 47 and rotate synchronously, provided that the number of copper wire hook assemblies 41 is the same as the number of copper wire pressing assemblies 42 and the number of upper ends of the corrugated copper wire.

[0027] The copper wire pressing assembly 42 includes a cylinder liner holder 4201 fixedly fitted onto the outer surface of the rotating shaft 46, the shape of which can be set according to the specifications of the corrugated copper wire, a plurality of fifth cylinders 4202 are mounted around the cylinder liner holder 4201, each fifth cylinder 4202 has an output end provided with a push-up rod connecting plate 4203 (the push-up rod connecting plate 4203 is reset by the elasticity of a second spring 4205), two symmetrically distributed push-up rods 4204 are fixedly provided on the side of the push-up rod connecting plate 4203 away from the adjacent fifth cylinder 4202, and the ends of the push-up rods 4204 away from the adjacent push-up rod connecting plate 4203 are slidably connected to a circular type II 45.

[0028] Each push-up rod connecting plate 4203 and the circular type II 45 are elastically connected via a second spring 4205, which is located between two adjacent push-up rods 4204. The circular type II 45 has multiple through grooves 4206 forming an annular array on the side away from the fifth cylinder 4202, and the end of the push-up rod 4204 away from the fifth cylinder 4202 extends into the through groove 4206 at the same horizontal position, and its role is as follows: When the fifth cylinder 4202 retracts and resets, the push-up rod 4204 slowly retracts from the through groove 4206 under the action of the second spring 4205, and at the same time, the copper wire pressing block 4207 retracts into the through groove 4206 under the action of the first spring 4208, preparing for the next copper wire pressing.

[0029] Inside the through groove 4206, there is a copper wire pressing section that limits the wave-wound copper wire. The copper wire pressing section includes a copper wire pressing block 4207, a first spring 4208, and a positioning block set 4209. The copper wire pressing block 4207 is located inside the through groove 4206 and is in contact with the adjacent push-up rod 4204. The end of the push-up rod 4204 that is in contact with the copper wire pressing block 4207 is inclined and is close to the axis of the rotation shaft 46 of the copper wire pressing block 4207. The end is an arc surface, the inclined surface is in contact with the arc surface, a through hole is made in the inner top wall of the through groove 4206 through which the copper wire pressing block 4207 passes, the copper wire pressing block 4207 is elastically connected to the inner wall of the through groove 4206 via first springs 4208 fixed on both sides, and is stopped and limited via a cover plate fixed to the side of the circular type II 45 closer to the circular type connecting member 47, and a positioning block set 4209 is attached to the outer surfaces of the circular type I 44 and the circular type II 45.

[0030] However, the positioning block set 4209 includes a lower positioning block set 4209a and an upper positioning block set 4209b, which are symmetrically positioned on both sides of the copper wire hooking assembly 41 (i.e., the lower positioning block set 4209a is located in circular type I 44, and the upper positioning block set 4209b is located in circular type II 45, and the lower positioning block set 4209a has two units used to correspond to the lower ends of two pins of the corrugated copper wire, and the upper positioning block set 4209b has three units used to correspond to the upper ends of three pins of the corrugated copper wire, thereby enabling the subsequent limit locking operation), and the upper positioning block set 4209b has a slope on the lower side of the side closer to the copper wire pressing block 4207. When the copper wire pressing block 4207 moves upward, it presses the pins of the corrugated copper wire downward on the slope, thereby enabling limit locking.

[0031] The copper wire hook assembly 41 is filled with air by an air-filling assembly 48 fixed to the bottom of the top plate 2. The air-filling assembly 48 includes a first fixing plate 4802 fixed to the bottom of the top plate 2 via a fixing column 4801. A third cylinder 4803 is attached to the top of the first fixing plate 4802, and the output end of the third cylinder 4803 passes through the top plate 2 and is fixed to a joint fixing plate 4804, whose role is as follows: When it is necessary to rapidly fill the quick joint II 4807 with air, the third cylinder 4803 pushes the interface fixing plate upward, bringing the quick joint I 4805 into contact with the quick joint II 4807, thereby achieving the purpose of air filling. Two quick joints I 4805 are attached to the joint fixing plate 4804 on the side closer to the copper wire hook assembly 41.

[0032] On the outside of the circular I44, air pipe adapter blocks 4806 corresponding to the number of copper wire pressing assemblies 42 are attached, and at the bottom of each air pipe adapter block 4806, two quick joints II 4807 are fixedly attached to communicate with quick joints I4805, and at the top of each air pipe adapter block 4806, a pair of elbows I4808 are further attached, each communicating with a quick joint II 4807 inside the same air pipe adapter block 4806, and each set of elbows I4808 passes through a through groove 4206 and communicates with elbow II 4809 at the air supply end of a gripper cylinder 4101 which is in the same horizontal position, and is used to supply air to the gripper cylinder 4101 of the copper wire hooking assembly 41, so that the copper wire hooking block 4102 can insert and remove copper wires.

[0033] However, since the structures of circular type I44 and circular type II45 are basically the same, the structural positions described in this embodiment are unaffected whether circular type I44 or circular type II45 is used as the reference object. The differences between the two are as follows: The through grooves 4206 opened inside circular type I44 and circular type II45 are different. The connecting through groove 4210 opened in circular type I44 is used to allow elbow I4808 to pass through, and the through groove 4206 in circular type II45 is used to position copper wire pressing block 4207. Circular type I44 has two protruding arcs, and circular type II45 has three protruding arcs, and the lower end of two pins and the upper end of three pins of the corrugated copper wire are limited via lower end positioning block set 4209a and upper end positioning block set 4209b attached to each of the protruding arcs.

[0034] In the 3D pre-forming machine for wave-wound wire in this embodiment, before pre-winding, the sliding plate 3202 is first pulled to the outermost edge of the top plate 2, the wave-wound copper wire is placed on the sliding plate 3202, and one pin on the outside of the wave-wound copper wire is placed in the copper wire groove to avoid positional misalignment problems during processing. Then, the sliding plate 3202 is pushed in the direction closer to the pre-winding means 4, so that the first upper end of the wave-wound copper wire is directly below the first pair of copper wire pressing parts. At this time, the fourth cylinder 3205 located on the upper end side of the wave-wound copper wire pushes the arc-shaped lower module 3206 and slides it in the direction of the pre-winding means 4, so that the arc-shaped lower module 3206 is placed directly below the upper end of the wave-wound copper wire, preparing for the pre-winding operation.

[0035] During the preliminary winding, the first upper end of the corrugated copper wire is located directly below the preliminary winding means 4, and the two arc-shaped lower modules 3206 are located at the upper and lower ends of the corrugated copper wire, respectively. The push-up cylinder 3102 pushes the push-up plate 3103 upward, bringing the two arc-shaped lower modules 3206 into contact with the two ends of the corrugated copper wire and pushing them upward, preparing to feed the corrugated copper wire into the preliminary winding means 4.

[0036] At this time, the fifth cylinder 4202 pushes the push-up rod connecting plate 4203, pushing the two push-up rods 4204 in the push-up rod connecting plate 4203 into the circular type II 45, and further pushes up the copper wire pressing block 4207, limiting the pins on both sides of the upper end of the corrugated copper wire between the upper end positioning block set 4209b and the copper wire pressing block 4207. Then the copper wire hooking assembly 41 hooks the middle part of the corrugated copper wire via the copper wire hooking block 4102. Subsequently, the drive assembly 43 rotates the rotating shaft 46, causing the copper wire pressing assembly 42 and the copper wire hooking assembly 41 to rotate synchronously, thereby enabling the winding of the hooked upper end of the corrugated copper wire. Immediately after the upper end is wound, the lower end of the pushed-up pin is pushed downward by the fourth cylinder 3205 towards the pre-winding means 4, and the limit of the lower end positioning block set 4209a simultaneously enables the winding operation. When the copper wire pressing assembly 42 at the next location rotates up to the top of the lifting assembly 31, it performs a pressing and hooking operation on the upper end of the next wave-wound copper wire, and by repeating this operation, the preliminary winding of the entire wave-wound copper wire is completed.

[0037] Furthermore, the structure of the present invention can be realized in multiple different forms and is not limited to the embodiments described above. Any equivalent transformation performed by those skilled in the art using the description and drawings of the present invention, or any application of such equivalent transformation directly or indirectly to other related technical fields (e.g., the field of attaching and detaching other articles), is within the scope of protection of the present invention.
