Description

Technical Field

[0001] The present invention belongs to the field of stator core processing equipment, and more specifically, relates to a forming device for the trapezoidal core block of a joint motor stator. Background Art

[0002] The stator core is a key component in electromagnetic devices such as motors, generators, and transformers. Its main function is to provide a magnetic circuit, improve the magnetic flux density of the device, and enhance the efficiency and performance of the motor.

[0003] The joint motor stator is relatively small in volume. It is formed by welding multiple trapezoidal core blocks together to be processed and embedded inside the joint motor, which is of great significance in improving the motor performance, reducing energy consumption, and enhancing control accuracy. Through reasonable material selection and structural design, the magnetic circuit characteristics of the motor can be optimized to meet the requirements of efficient and precise control.

[0004] The Chinese patent with the authorization announcement number CN111756196A discloses a stator core assembly system and a stator core assembly method, including: a tooling plate for loading the stator core; a conveying line for transporting the tooling plate; an auxiliary installation device installed in parallel with the conveying line, which is used to position the tooling plate and assemble the core assembly blocks into a circular stator core; a forming and pressing device installed in parallel with the conveying line and located on one side of the auxiliary installation device, which is used to position the tooling plate and press the stator core to the same height; a forming and shaping device installed in parallel with the conveying line and located on one side of the forming and pressing device, which is used to position the tooling plate and shape the stator core to adjust the roundness of the stator core; a welding device installed in parallel with the conveying line and located on one side of the forming and pressing device, which is used to position the tooling plate and weld the stator core; a blanking device arranged on one side of the conveying line, which is used to position the tooling plate and remove the stator core from the tooling plate.

[0005] The above technical solution has the following defects: For the overall processing and production process of the stator core of the joint motor, it processes the core assembly blocks rather than individual trapezoidal core blocks, and does not have the function of winding and forming multiple independent trapezoidal core blocks, that is, it cannot achieve the automatic forming function of processing raw materials into a complete stator. At the same time, there is a certain distance between each processing mechanism, and a conveying line is required for transportation, resulting in a relatively large volume of the overall equipment.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figure 1 shown, this embodiment provides a forming device for the trapezoidal iron core block of a joint motor stator, including a workbench 1. A wire winding assembly 2 for winding round copper wire on the iron core block, a wire adjusting assembly 3 for ensuring uniform winding of the round copper wire during the winding process, and a forming tooling 4 for forming the iron core block are installed on the top of the workbench 1; As Figures 6 to 15 shown, the working principle of the forming tooling 4 is as follows: when the bevel cutting disc 435 moves upward, it squeezes the lower end of the pressing block 432, so that the upper end of the pressing block 432 approaches the trapezoidal iron core block 5, realizing the pressing of the trapezoidal iron core block 5, and adjacent trapezoidal iron core blocks 5 form a weld ( Figure 8As shown by B in , after pressing and fixing multiple trapezoidal iron core blocks 5, the welding device welds the weld seams to complete the welding of multiple trapezoidal iron core blocks 5 into a complete stator. The specific structure is as follows: The forming tooling 4 includes a flipping member 42 fixed on the upper surface of the workbench 1 and a fixing plate 41 installed at the flipping member 42. On one side of the upper surface wall of the fixing plate 41, a bearing seat II 8 is fixedly installed. A bearing 9 is embedded inside the bearing seat II 8. A rotating flange 7 is fixedly installed at one end of the bearing 9, and an end cover 10 is fixedly installed at the other end of the bearing 9. A handle 11 is fixedly installed on the end cover 10 to achieve the purpose of rotating the entire tooling. At the fixing plate 41, a splicing assembly 43 for limiting the trapezoidal iron core block 5, a manual clamping assembly 44 for pressing the outer end of the trapezoidal iron core block 5, an end face pressing assembly 45 for clamping the top of the trapezoidal iron core block 5, and a circumferential positioning assembly 46 for preventing deviation during welding are installed.

[0034] Specifically, the splicing assembly 43 includes a splicing tooling plate 431, a plurality of pressing blocks 432, a cam follower 433, a connecting shaft 434, and an inclined cutting disk 435; A plurality of pressing blocks 432 are slidably arranged in an annular array inside the splicing tooling plate 431. A plurality of uniformly distributed connecting shafts 434 are fixed at the bottom of the splicing tooling plate 431. The inclined cutting disk 435 is sleeved and slid on the outside of the connecting shaft 434 through a reserved hole. A plurality of uniformly distributed cam followers 433 are fixed on the outer ring of the splicing tooling plate 431. At the same time, a plurality of equally spaced limiting grooves 439 are opened on the inner ring of the splicing tooling plate 431 for corresponding to the sliding of each pressing block 432, so as to achieve the purpose of pressing and loosening the pressing block 432 on the trapezoidal iron core block; At the upper end of the pressing block 432, a pressing protrusion 4321 integrally formed therewith is provided. The pressing protrusion 4321 can press against the side surface of the trapezoidal iron core block 5. The pressing protrusion 4321 is mutually adapted to the limiting U-shaped groove 437. At the lower end of the pressing block 432, a spring pressing block 4322 integrally formed therewith is provided. A through groove 4323 symmetrically opened with the spring pressing block 4322 is opened at the inner ring 436. A return spring 4324 is arranged inside the through groove 4323. The return spring 4324 is fixed to the inner wall of the through groove 4323. A groove in contact with the return spring 4324 is opened on one side of the spring pressing block 4322 close to the return spring 4324. And the side of the pressing block 432 close to the inclined cutting disk 435 is an inclined surface. During the upward movement of the inclined cutting disk 435, the inclined surface is extruded to achieve the purpose of the pressing block 432 approaching the trapezoidal iron core block 5 (the pressing protrusion 4321 at the upper end of the pressing block 432 passes through the limiting U-shaped groove 437 and abuts against the outer side wall of the trapezoidal iron core block 5). After the inclined cutting disk 435 moves downward and resets, the pressing block 432 moves back into the through groove 4323 under the action of the return spring 4324 to prepare for the next pressing process; The inner ring of the splicing tooling plate 431 is provided with an inner ring 436 integrally formed therewith. The inner ring 436 is provided with a number of limiting U-shaped grooves 437 equal to the number of trapezoidal iron core blocks 5 to limit the upper end of the pressing block 432 and ensure the accuracy of the pressing position.

[0035] Specifically, the manual clamping assembly 44 includes a docking plate 441, a positioning plate 442, a spring clip 443 and an elbow clamp 444; The positioning plate 442 is fixedly connected to the docking plate 441 through the spring clip 443. One end of the connecting shaft 434 away from the splicing tooling plate 431 is fixedly connected to the positioning plate 442. The elbow clamp 444 is fixedly installed in the middle of the positioning plate 442. The output end of the elbow clamp 444 is fixedly connected to the bottom of the bevel cutting disc 435, which can move the bevel cutting disc 435 up and down along the vertical direction of the connecting shaft 434.

[0036] Specifically, the end face pressing assembly 45 includes a pressing disc positioning shaft 451, an end face pressing disc 452 and a pressing wheel 453; the pressing disc positioning shaft 451 is fixedly installed in the middle of the upper surface of the splicing tooling plate 431 and is coaxially connected to the splicing tooling plate 431. The end face pressing disc 452 is slidably sleeved on the upper end of the pressing disc positioning shaft 451 to ensure that the end face pressing disc 452 can have a certain floating range. When the pressing wheel 453 is rotated in the direction close to the pressing disc positioning shaft 541, the pressing wheel 453 presses the end face pressing disc 452. When the reverse rotation of the pressing wheel 453 releases the limit on the end face pressing disc 452, the slidable end face pressing disc 452 is also convenient for the taking and placing of the trapezoidal iron core block; the pressing wheel 453 is threadedly connected to the thread ring at the upper end of the pressing disc positioning shaft 451. After the pressing block 432 abuts against the side of the trapezoidal iron core block 5, the pressing wheel 453 is tightened so that the end face pressing disc 452 presses the upper end face of the trapezoidal iron core block 5. After the positioning of the trapezoidal iron core block 5 is completed, the welding effect is ensured; At the same time, the positioning inner sleeve 438 is fixedly installed on the splicing tooling plate 431 (inside the inner ring 436) and is coaxially arranged therewith. The pressing disc positioning shaft 451 is arranged inside the positioning inner sleeve 438. A plurality of limiting strips 14 are arranged on the outer peripheral wall of the positioning inner sleeve 438 in an annular array. The trapezoidal iron core block 5 is placed between adjacent limiting strips 14. A convex block 13 integrally formed with the outer side wall of the positioning inner sleeve 438 is arranged at the lower end between adjacent limiting strips 14. While the trapezoidal iron core block 5 is limited by the two limiting strips 14, the convex block 13 supports the trapezoidal iron core block 5 to realize preliminary circumferential forming and prepare for the subsequent positioning and pressing work.

[0037] Specifically, the circumferential positioning assembly 46 includes a positioning mounting plate 461, a slide rail II 462, a spring limiting rod 463, a spring limiting block 464, a compression spring 465 and a fine positioning block 466; The positioning and mounting plate 461 is fixedly mounted on the side wall of the bearing block II8, the slide rail II462 is fixedly mounted on the positioning and mounting plate 461, spring limit blocks 464 are symmetrically mounted on both sides of the positioning and mounting plate 462, each spring limit rod 463 is slidably disposed through the spring limit block 464, a compression spring 465 is sleeved on each spring limit rod 463, the precise positioning block 466 is slidably disposed on the slide rail II462, and a pull handle 467 for pulling is mounted on the outer surface. The two spring limit rods 463 at the same positioning and mounting plate 461 are respectively fixedly connected to the upper ends of both sides of the precise positioning block 466. The two ends of the compression spring 465 are respectively in contact with the adjacent sides of the precise positioning block 466 and the spring limit block 464. When welding the weld seam is required, the upper end of the precise positioning block 466 is engaged with the corresponding cam follower 433 to prevent the forming tooling 4 from shifting in the circumferential direction during the welding process, resulting in welding misalignment and insecure welding.

[0038] During the working process, the flipping member 42 flips the entire forming tooling 4 to the vertical direction. The trapezoidal iron core blocks 5 are placed one by one between the limiting strips 14 on the outer peripheral wall of the positioning inner sleeve 438. After the trapezoidal iron core blocks 5 are placed on the outer peripheral wall of the positioning inner sleeve 438, the toggle clamp 444 is pulled to move the bevel cutting disc 435 upward, and at the same time, a plurality of pressing blocks 432 are squeezed, so that the abutting protrusions 4321 at the upper ends of the pressing blocks 432 abut against the outside of the trapezoidal iron core blocks 5. Subsequently, the pressing wheel 453 is tightened so that the end face pressing disc 452 fully presses on the ends of the plurality of trapezoidal iron core blocks 5, achieving the purpose of positioning while correcting. After the positioning of the trapezoidal iron core blocks 5 is completed, the flipping member 42 flips the entire forming tooling 4 by 90 degrees, facilitating the welding mechanism (a traditional welding device is sufficient) to weld the weld seam. To prevent the forming tooling 4 from shifting in the circumferential direction during the welding process, the precise positioning block 466 is engaged with the corresponding cam follower 433 to limit the splicing tooling disc 431. After welding one weld seam, the precise positioning block 466 releases the limit on the cam follower 433. Then, the rotation flange 7 is rotated by driving the handle 11 to rotate, so that the entire forming tooling 4 rotates, enabling the next cam follower 433 to be engaged with the precise positioning block 466 to weld the next weld seam. After the welding is completed, it is rotated and adjusted again until all weld seams are welded. It should be noted that the fixing plate 41 is mounted on the flipping member 42. The flipping member 42 can be a mechanical mechanism (such as a traditional rotating shaft structure) or a motor, as long as it can achieve the purpose of flipping the forming tooling 4. Specifically, as Figures 2 to 6As shown in the figure, the winding assembly 2 includes a bearing block I 21 installed on the upper surface of the workbench 1. One side of the bearing block I 21 is installed with a winding part 23 for winding through a rotating shaft 22. When winding, first limit the trapezoidal iron core block 5 on one side of the mounting block 231, and rotate the winding part 23 by the handle provided on the rotating shaft 22 to achieve the purpose of winding the trapezoidal iron core block 5; Specifically, the winding part 23 includes a mounting block 231, a winding column 232, a pressing plate 233 and a pressing handle 234; The mounting block 231 is fixedly installed at the end of the rotating shaft 22. The winding column 232 is movably installed at the side end of the mounting block 231. One end of the pressing plate 233 is hinged to the top of the mounting block 231. A chute 235 for placing the trapezoidal iron core block 5 is opened on the side surface of the mounting block 231. The pressing handle 234 is threadedly connected to the screw hole at the bottom of the mounting block 231; As Figure 3 shown in the figure, a groove is opened at one end of the pressing plate 233 close to the winding column 232 for the winding column 232 to pass through, and it does not affect the pressing plate 233 to limit and press the trapezoidal iron core block 5. The function of the winding column 232 is that when winding, first wind the end of the copper wire around the winding column 232 to fix one end of the copper wire for subsequent winding work.

[0039] The winding column 232 is inserted into the jack 236 opened in the mounting block 231. A pin hole 237 communicating with the jack 236 is also opened on the surface of the mounting block 231 on the same side as the trapezoidal iron core block 5. A through hole adapted to the pin hole 237 is opened at the winding column 232. Internal threads adapted to the bolt are provided inside the through hole. The bolt sequentially passes through the pin hole 237 and extends into the inside of the through hole to be threadedly connected thereto, so that the winding column 232 is fixed on one side of the mounting block 231.

[0040] Specifically, the wire adjusting assembly 3 includes a lead screw fixing seat 31 and a slide rail I 32 installed on the upper surface of the workbench 1. A sliding plate 33 is slidably installed on the top of the slide rail I 32. The lead screw fixing seat 31 drives the nut fixing seat 35 threadedly connected to its external thread ring through a trapezoidal lead screw 34 rotatably installed inside. The nut fixing seat 35 is installed at the sliding plate 33 through bolts. A wire guiding seat 36 is fixed on the top of the sliding plate 33. A wire guiding roller 37 is installed at one end of the wire guiding seat 36 close to the trapezoidal lead screw 34. A wire guiding groove for the round copper wire to pass through is penetratedly opened on the wire guiding roller 37. During the wire winding process, rotate the trapezoidal lead screw 34 to make the nut fixing seat 35 reciprocally slide along the axial direction of the trapezoidal lead screw 34, so that the sliding plate 33 drives the wire guiding roller 37 to slide back and forth to ensure uniform wire winding during the wire winding process.

[0041] First, wind the round copper wire around a single trapezoidal iron core block through the winding assembly 2 and the wire adjusting assembly 3, and then use the forming tooling 4 to enclose multiple wound trapezoidal iron core blocks into a circle to facilitate welding and processing into a stator.

[0042] It should be noted that, as Figure 4 shown, the trapezoidal iron core block 5 is composed of a trapezoidal block 6 and two patch pieces 238. The trapezoidal block 6 slides into the interior of the mounting block 231 through the chute 235. The pressing plate 233 is flipped down to press the trapezoidal block 6 inside the chute 235. Subsequently, the pressing handle 234 is tightened so that the pressing plate 233 does not shake, ensuring the stability of the trapezoidal block 6. Then, the two patch pieces 238 are clamped onto the trapezoidal block to complete the process of forming the trapezoidal iron core block 5.

[0043] It should be noted that the structure described in the present invention can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other articles, is included in the protection scope of the present invention.
