Description

Technical Field

[0001] The present invention relates to the technical field of motor manufacturing, and particularly to a shaping device for the end part of the armature winding of a brushless motor. Background Art

[0002] The armature is a motor component that plays a key and pivotal role in the process of mutual conversion between mechanical energy and electrical energy of the motor. It includes an armature core and an armature winding. The armature winding is the circuit part of the motor and is also the part that induces electromotive force and generates electromagnetic torque for electromechanical energy conversion. The winding is embedded in the slots of the core and is also an important component of the armature. Therefore, the armature winding largely affects the manufacturing quality, lifespan, and operation of the motor.

[0003] When the armature winding is wound and embedded in the core slots, the inner and outer diameters and height dimensions of its two ends do not conform to the design dimensions, and manual intervention is required for shaping. The traditional shaping process of the armature winding is entirely carried out manually, which has a certain labor intensity, and the consistency of the shaping quality of the armature winding is poor and the efficiency is low.

[0004] The current winding shaping method is manual shaping. First, use pliers with the tip wrapped with cloth tape to clamp the inner circle outward with force until it reaches approximately the right size to ensure that the rubber stick can be inserted. Then, hold a round rubber stick in one hand and insert it into the inner circle, and hold a rubber hammer in the other hand to strike the outer circle of the winding. While constantly striking, rotate the core, and the unqualified positions need to be repeatedly checked and struck. This process has a certain labor intensity and usually requires high physical fitness of the employees. After the inner and outer diameters are shaped qualified, the armature is placed in the shaping mold, and a press is used to press and shape the height of the winding. Using the manual shaping method to ensure the shape and size of the winding end, the whole process is cumbersome, time-consuming, and the quality consistency cannot be improved either.

[0005] In order to solve the problems existing in manual shaping, shaping devices have emerged in the prior art. For example, the patent application with the publication number CN115333304A discloses a shaping device for the end part of a DC motor armature. During operation, the armature is vertically installed on the base, several pressing blocks are wrapped around the outside of the armature, a fixing ring is sleeved on the several pressing blocks, and then the circular groove on the lower surface of the pressing sleeve is embedded in the upper ends of the several pressing blocks, and the protrusion in the center of the circular groove is inserted into the inner circle formed by the several pressing blocks. A power device is used to apply a downward load to the pressing sleeve, and the upper ends of the several pressing blocks move closer to each other to compress the outer circle of the end part of the armature to be shaped, and the protrusion of the pressing sleeve compresses the height of the end part of the armature to be shaped until the size of the end part of the armature to be shaped meets the requirements, then the loading is stopped and the armature is taken out.

[0006] However, the above-mentioned prior art uses the extrusion method for shaping, which can only ensure the height and outer circle of the end part to be shaped, and cannot shape the inner circle of the end part to be shaped. Summary of the Invention

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Combined with Figures 1 to 8 As shown, a shaping device for the end of the armature winding of a brushless motor includes a frame 1, on the workbench of the frame 1, a back plate 2 and a base servo mechanism 3 are provided; on the back plate 2, an upper pressing servo mechanism 4, a left pressing servo mechanism 5 and a right pressing servo mechanism 6 are installed; the base servo mechanism 3 is used to clamp the armature 100 and drive the armature 100 to rotate around its own axis; on the upper pressing servo mechanism 4, an upper roller 401 is provided for rolling the upper end face of the armature 100; on the left pressing servo mechanism 5, a left roller 501 is provided for rolling the outer cylindrical surface of the upper part of the armature 100; on the right pressing servo mechanism 6, a roller column 601 is provided for rolling the inner hole surface of the upper part of the armature 100.

[0042] In this embodiment, the upper pressing servo mechanism 4 is used to drive the upper roller 401 to move up and down. The left pressing servo mechanism 5 is used to drive the left roller 501 to move left and right. The right pressing servo mechanism 6 is used to drive the roller column 601 to move up and down and to achieve left and right movement.

[0043] By adopting the above device, when shaping the armature 100, the armature 100 is installed on the base servo mechanism 3, and the end to be shaped of the armature 100 faces upward. By using the upper pressing servo mechanism 4 to drive the upper roller 401 to move downward and press tightly on the top end surface of the armature 100, by using the left pressing servo mechanism 5 to drive the left roller 501 to move rightward and abut against the outer peripheral surface of the shaping end of the armature 100; by using the right pressing servo mechanism 6 to drive the roller column 601 to move leftward and downward, so that the roller column 601 is inserted into the inner hole of the end to be shaped of the armature 100, and then by using the right pressing servo mechanism 6 to drive the roller column 601 to move rightward, so that the roller column 601 abuts tightly against the inner hole surface of the armature 100. The base servo mechanism 3 drives the armature 100 to rotate around its own axis to complete the shaping operation.

[0044] Combined with Figure 3As shown, in this embodiment, the base servo mechanism 3 includes a base 301, a three-jaw chuck 302, and a driving motor 303; the three-jaw chuck 302 is used for clamping the armature 100 to be shaped. The base 301 is fixedly installed on the workbench of the frame 1; the driving motor 303 is installed on the bottom surface of the workbench of the frame 1; the three-jaw chuck 302 is rotatably installed on the base 301, and the output shaft of the driving motor 303 is connected to the three-jaw chuck 302. The driving motor 303 is used to drive the three-jaw chuck 302 to rotate, and thus can drive the armature 100 clamped on the three-jaw chuck 302 to rotate around its own axis.

[0045] Combined with Figure 3 and Figure 4 As shown, the three-jaw chuck 302 is a pneumatic three-jaw chuck. The three-jaw chuck 302 includes clamping jaws 309. A limiting shaft 304 is inserted in the center of the three-jaw chuck 302, and a positioning mandrel 305 is inserted at the top of the limiting shaft 304; the positioning mandrel 305 is used to be inserted into the central hole of the armature 100; when the clamping jaws 309 abut against the outer peripheral surface of the limiting shaft 304, the clamping jaws 209 clamp the armature 100; a tightening screw 306 is screwed on the limiting shaft 304 to tighten the positioning mandrel 305. When clamping the armature 100, the armature 100 is sleeved on the positioning mandrel 305 to form a preliminary positioning. Then, when the clamping jaws 309 move radially inward to clamp the armature 100, since the limiting shaft 304 plays a limiting role, it can prevent the clamping jaws 309 from over-clamping the armature 100 and avoid deformation of the armature 100 due to over-clamping. That is, when the clamping jaws 309 abut against the outer peripheral surface of the limiting shaft 304 to form a limit, at this time, the clamping jaws 309 can clamp the armature 100.

[0046] Combined with Figure 5 As shown, vertical grooves 307 are formed on the clamping surfaces of the clamping jaws 309, and urethane rubber 308 is embedded in the grooves 307. When clamping the armature 100, the urethane rubber 308 contacts the outer circle of the armature 100, so the urethane rubber 308 plays a buffering and protective role to avoid scratching the armature 100. Further, a plurality of gaskets 310 are arranged between the urethane rubber 308 and the bottom of the groove 307. By adjusting the thickness of the gaskets 310, the height of the urethane rubber 308 protruding from the clamping surface of the clamping jaws 309 can be adjusted, and thus the magnitude of the clamping force can be adjusted.

[0047] Combined with Figure 6As shown in the figure, the upper pressing servo mechanism 4 includes a first base plate 402 and a first servo motor 409; the first base plate 402 is installed on the back plate 2 through a first bracket 7; a first mounting plate 403 is provided on the front surface of the first base plate 402; the first servo motor 409 is installed on the top surface of the first mounting plate 403; two vertical first guide blocks 404 are provided on the front surface of the first base plate 402, and a first slider 405 is slidably installed in the guide chutes of the two first guide blocks 404; the lower end of the first slider 405 is installed with a first wheel seat 407 through a first adapter plate 406; the upper roller 401 is installed on the first wheel seat 407 through a first rotating shaft 408; the output shaft of the first servo motor 409 is connected with a first lead screw (not shown in the figure), and the first lead screw is in threaded cooperation with the first slider 405. By adopting the above structure, by driving the first lead screw to rotate by using the first servo motor 409, the first slider 405 can be driven to slide up and down, and then the upper roller 401 can be driven to move up and down.

[0048] Furthermore, a first weighing sensor 410 is provided between the first adapter plate 406 and the first mounting plate 403. The first weighing sensor 410 is used to monitor the pressure between the first adapter plate 406 and the first mounting plate 403, and then the vertical pressure of the upper roller 401 on the top surface of the armature 100 can be indirectly monitored.

[0049] Combined with Figure 7 As shown in the figure, the left pressing servo mechanism 5 includes a second base plate 502 and a second servo motor 509; the second base plate 502 is installed on the back plate 2 through a second bracket 8; a second mounting plate 503 is provided on the front surface of the second base plate 502; the second servo motor 509 is installed on the left end surface of the second mounting plate 503; two horizontal second guide blocks 504 are provided on the front surface of the second base plate 502, and a second slider 505 is slidably installed in the guide chutes of the two second guide blocks 504; the right end of the second slider 505 is installed with a second wheel seat 507 through a second adapter plate 506; the left roller 501 is installed on the second wheel seat 507 through a second rotating shaft 508; the output shaft of the second servo motor 509 is connected with a second lead screw (not shown in the figure), and the second lead screw is in threaded cooperation with the second slider 505. By adopting the above structure, by driving the second lead screw to rotate by using the second servo motor 509, the second slider 505 can be driven to slide left and right, and then the left roller 501 can be driven to move left and right.

[0050] Further, a second weighing sensor 510 is disposed between the second adapter plate 506 and the second mounting plate 503. The second weighing sensor 510 is used to monitor the pressure between the second adapter plate 506 and the second mounting plate 503, and thus can indirectly monitor the lateral pressure of the left roller 101 on the outer cylindrical surface of the armature 100.

[0051] Combined Figure 8 As shown, the right pressing servo mechanism 6 includes a third base plate 602 and a third servo motor 609; the third base plate 602 is mounted on the back plate 2 through a third bracket 9; a third mounting plate 603 is provided on the front surface of the third base plate 602; the third servo motor 609 is mounted on the right end surface of the third mounting plate 603; two horizontal third guide blocks 604 are provided on the front surface of the third base plate 602, and a third slider 605 is slidably mounted in the guide chutes of the two third guide blocks 604; the left end of the third slider 605 is mounted with a thin cylinder 607 through a third adapter plate 606; the roller column 601 is rotatably mounted on the telescopic rod of the thin cylinder 607 through a coupling 608; the output shaft of the third servo motor 609 is connected with a third lead screw (not shown in the figure), and the third lead screw is in threaded cooperation with the third slider 605. By adopting the above structure, by driving the third lead screw to rotate by using the third servo motor 909, the third slider 605 can be driven to slide left and right, and the telescopic rod of the thin cylinder 607 can perform lifting motion. Therefore, the right pressing servo mechanism 6 can drive the roller column 601 to move up and down and move left and right.

[0052] Further, a third weighing sensor 610 is disposed between the third adapter plate 606 and the third mounting plate 603. The third weighing sensor 610 is used to monitor the pressure between the third adapter plate 606 and the third mounting plate 003, and thus can indirectly monitor the lateral pressure of the roller column 601 on the inner hole surface of the armature 100.

[0053] In this embodiment, the first weighing sensor 410, the second weighing sensor 510, and the third weighing sensor 610 all adopt UTTC-5KN compression type weighing sensors. UTTC-5KN is a force measuring sensor that supports both tension and compression and is suitable for high-precision force measurement.

[0054] When extruding and shaping the armature 100, the method of rotating one circle forward and one circle backward is adopted for shaping. The first circle of shaping of the armature 100 is rough shaping, and the second circle is final shaping. As long as there is a certain amount of shaping for the winding during the first circle of shaping, while during the second circle of shaping, it is necessary to ensure that the inner and outer circle dimensions of the winding are in place. The shaping amounts of the two times should not differ greatly, otherwise there is a risk of damaging the winding.

[0055] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
