Detailed Embodiment

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the following further elaborates on the utility model in combination with the drawings and embodiments.

[0027] Embodiment 1

[0028] In one embodiment, as Figures 1-7 shown, an automatic and efficient winding tooling for a starting motor of a new energy vehicle includes a mounting and fixing block 100. An adjustable inner support structure 200 for positioning the stator is provided at the upper end of the mounting and fixing block 100. The adjustable inner support structure 200 includes a plurality of inner support blocks 201 distributed in an array. The T-shaped slider 202 at the lower end of the inner support block 201 is slidably matched with the T-shaped chute 203 at the upper end of the mounting and fixing block 100. The plurality of inner support blocks 201 form an expansion ring for positioning the inner wall of the stator. An expansion driving member 300 for driving the inner support block 201 to move along the diameter direction of the expansion ring is connected to the inner side of the inner support block 201. Through the above settings, when the stator is installed on this tooling, the inner support block 201 in the adjustable inner support structure 200 can expand and move to adjust this tooling to adapt to different stator specifications.

[0029] In one embodiment, as Figure 6 shown, the expansion driving member 300 includes a cylindrical mounting shell 301 movably arranged at the upper end of the mounting and fixing block 100. The cylindrical mounting shell 301 is coaxially arranged with the expansion ring. A vertical chute 302 is vertically opened on each inner support block 201. A lower support block 303 is slidably arranged in each vertical chute 302. A sliding clamping groove 304 for clamping with the inner support block 201 is arranged on the outer side of the lower support block 303. A first screw rod 305 is fitted in the threaded hole at the inner end of the lower support block 303. The other end of the first screw rod 305 is rotatably connected to the inner support block 201. A first bevel gear 306 is arranged at the end of the first screw rod 305 passing through the inner support block 201. The plurality of first bevel gears 306 are meshed with a second bevel gear 307. The lower end of the second bevel gear 307 is connected to a second driving motor 308 for driving it to rotate. The second driving motor 308 is arranged at the inner bottom of the inner support block 201. Through the above settings, the sliding clamping groove 304 arranged on the lower support block 303 enables the lower support block 303 to only move up and down along the vertical chute 302 and cannot move horizontally. At the same time, the second driving motor 308 can drive the second bevel gear 307 to drive the first bevel gear 306 to rotate, so that the lower support block 303 pushes the inner support block 201 to expand and move.

[0030] In one embodiment, as Figure 4 shown, the outer end of the lower support block 303 extends out of the inner support block 201, and a support surface for supporting the bottom of the stator is arranged at the end of the lower support block 303. Through the above settings, the lower support block 303 can stably support the stator and assist in positioning the stator on this tooling.

[0031] In one embodiment, as Figure 1As shown, an auxiliary positioning member 400 for pressing the upper end of the stator is further provided on the installation and fixing block 100. The auxiliary positioning member 400 includes an L-shaped mounting bracket 401 fixed to the upper end of the installation and fixing block 100. The end of the L-shaped mounting bracket 401 extends above the adjustable inner support structure 200. A hydraulic push rod 402 is provided at the end of the L-shaped mounting bracket 401. The output end of the hydraulic push rod 402 is connected to a detachable winding base 403 for positioning the top of the stator. The detachable winding base 403 is distributed with pin shafts 404 for assisting in winding. Through the above settings, after the stator is installed, the detachable winding base 403 can be pushed by the hydraulic push rod 402 to tightly press the stator, preventing the stator from bouncing during the subsequent winding process. At the same time, the pin shafts 404 provided on the detachable winding base 403 can assist in the subsequent winding work.

[0032] In one embodiment, as Figure 5 shown, the lower end of the cylindrical mounting shell 301 is connected to a lifting seat 500. A shear rod group 600 is provided at the lower end of the lifting seat 500. Each shear rod group 600 includes a first support rod 601 and a second support rod 602 that are rotatably connected. The upper slider 603 at the upper ends of the first support rod 601 and the second support rod 602 is slidably connected to the chute 604 at the bottom of the lifting seat 500. The lower slider 605 at the lower ends of the first support rod 601 and the second support rod 602 is connected to a threaded pushing member 700 for driving them to approach or separate from each other. Through the above settings, the first support rod 601 and the second support rod 602 can lift the upper lifting seat 500 under the action of the threaded pushing member 700 to achieve the function of height adjustment.

[0033] In one embodiment, as Figure 5 shown, the threaded pushing member 700 includes a second screw rod 701 passing through the lower slider 605. One end of the second screw rod 701 is rotatably connected to a groove formed in the installation and fixing block 100. A first gear 702 is provided at the other end of the second screw rod 701. The first gear 702 meshes with a second gear 703. The output end of the second gear 703 is provided with a first driving motor 704. Through the above settings, when the first driving motor 704 operates, the second gear 703 will rotate, and at the same time drive the first gear 702 to rotate, so that the second screw rod 701 rotates to achieve the function of the lower sliders 605 approaching or separating from each other.

[0034] In one embodiment, as shown in 5, the shear rod groups 600 are mirror-symmetrically arranged on both sides of the lower end of the lifting seat 500. Through the above settings, the combined action of the two shear rod groups 600 can make the lifting and lowering more stable.

[0035] Embodiment 2

[0036] In one embodiment, asFigure 6 As shown, the size of the first bevel gear 306 is one-fourth of the size of the second bevel gear 307. With the above arrangement, the rotation of the second bevel gear 307 can synchronously operate the four first bevel gears 306, enabling the inner support block 201 to expand stably.

[0037] The above embodiment discloses an automatic and efficient winding tooling for a starting motor of a new energy vehicle. In this tooling, the lifting seat 500 is driven by a first driving motor 704 to rotate the second screw rod 701, thereby adjusting the angles of the first support rod 601 and the second support rod 602, and then adjusting the height of the tooling to adapt to the stator. Subsequently, the inner support block 201 in the adjustable inner support structure 200 adjusted by the expansion driving member 300 expands and contracts to adapt to the inner diameters of different specifications of stators. Finally, the hydraulic push rod 402 provided on the L-shaped mounting bracket 401 drives the detachable winding seat 403 to press the stator tightly to prevent the stator from bouncing during winding.

[0038] As mentioned above, the above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
