DETAILED DESCRIPTION

[0027] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In an exemplary embodiment, Figure 1-5 As shown, this embodiment provides a stator wire shaping and cutting mechanism, which includes a first moving block 1 and a second moving block 2 which are laterally opposed, and a first shearing knife 3 which is fixedly mounted on the first moving block 1, and a second shearing knife 4 which is fixedly mounted on the second moving block 2, wherein the first shearing knife 3 and the second shearing knife 4 are opposed to each other and staggered up and down; and further includes a first shaping portion 5 and a second shaping portion 6 which are respectively connected to the first moving block 1 and the second moving block 2 and are respectively located below the first shearing knife 3 and the second shearing knife 4, and the first shaping portion 5 and the second shaping portion 6 can be combined to form a shaping channel for the stator wire 7 to pass through.

[0030] In the above embodiment, during the wire cutting process, the stator wire 7 to be cut is surrounded in the shaping channel, and the first cutting knife 3 and the second cutting knife 4 cut the stator wire 7 exposed from the shaping channel. The stator wire 7 is protected by the shaping channel and will not deviate, thereby ensuring accurate wire cutting, solving the problem in the prior art that the stator wire 7 may deviate during the wire cutting process, resulting in low wire cutting accuracy.

[0031] Furthermore, the cutting structure further comprises a first mounting frame 9, the first moving block 1 and the second moving block 2 are respectively slidably mounted on the first mounting frame 9, and the first mounting frame 9 is also respectively fixedly connected with two first telescopic drivers 10 driving the first moving block 1 and the second moving block 2, that is, a slide rail 22 is arranged on the first mounting frame 9 for the first moving block 1 and the second moving block 2 to slide back and forth under the drive of the corresponding first telescopic driver 10. When cutting the wire, the stator 8 is located in the middle position of the first mounting frame 9, and the stator wire 7 to be cut is located between the first shaping part 5 and the second shaping part 6. The operation of the first telescopic driver 10 causes the first shaping part 5 and the second The shaping part 6 closes and surrounds the shaping channel, and makes the corresponding stator wire 7 located in the shaping channel, and the first telescopic driver 10 further drives the first shearing knife 3 and the second shearing knife 4 to cut the stator wire 7 exposed outside the shaping channel; specifically, there are multiple groups of stator wires 7 to be cut on the stator 8, and one group has two stator wires. When cutting, the two stator wires 7 are positioned together in the shaping channel and then cut. Then, the first telescopic driver 10 drives in the reverse direction to separate the first shearing knife 3, the second shearing knife 4, the first shaping part 5 and the second shaping part 6, and then runs again to cut the next group of stator wires 7. After repeating multiple times, multiple groups of stator wires 7 can be cut.

[0032] like Figure 1-8 As shown, in a further exemplary embodiment, the shearing mechanism further includes a second mounting frame 11, to which a second telescopic driver 12 is fixedly connected, the second telescopic driver 12 has an output end extending upward, and the output end is also rotatably connected to a lifting rod 13 located below the shaping channel (a rotation groove is recessed on the lower end surface of the lifting rod 13, and the upper end of the output end is rotated and inserted into the rotation groove), and a first driving motor 14 that drives the lifting rod 13 to rotate is also fixedly installed on the second mounting frame 11. The second telescopic driver 12 is similar to the first telescopic driver 10, and can be a cylinder or an electric push rod. In order to realize reciprocating drive, the second telescopic driver 12 drives the lifting rod 13 up and down through the output end, and the stator 8 can be placed on the lifting rod 13 to move up and down. After cutting a group of stator wires 7, the lifting rod 13 is driven to rotate by the first driving motor 14, so that the stator 8 rotates to rotate to rotate the next group of stator wires 7 for cutting; more specifically, the first driving motor 14 is connected to the driving gear 15, and the lifting rod 13 is fixedly connected to the driven gear 16 meshing with the driving gear 15, so that the first driving motor 14 can indirectly drive the lifting rod 13 to rotate by driving the driving gear 15.

[0033] like Figure 1-7As shown, in a further exemplary scheme, a pair of conveyor belts 17 are fixedly provided on the second mounting frame 11, and a pallet 18 is placed between the two conveyor belts 17, and the pallet 18 can be placed on the two conveyor belts 17 and moved between the shaping channel and the lifting rod 13, and the bottom surface of the pallet 18 is also provided with a top hole for the lifting rod 13 to push in or out, and the lifting rod 13 and the top hole are mutually matched polygonal structures, such as a square structure, so that the two can rotate synchronously and can be disengaged downward in the vertical direction; the two conveyor belts 17 are used for the movement of the pallet 18 to move the stator 8 from the outside to the bottom of the shaping channel, and then be lifted by the lifting rod 13. Specifically, the pallet 18 connected to the lifting rod 13 is directly placed on the stator 8, and the stator 8 is placed on the pallet 18. A positioning hole 19 for positioning the stator 8 (i.e., a positioning hole 19 for accommodating the lower end of the stator 8) can also be provided, so that the stator 8 can be more stable when moving on the two conveyor belts 17, and the lifting rod 13 and the support plate 18 can be disengaged, so that the support plate 18 can move smoothly on the two conveyor belts 17, which is convenient for the stator 8 to be sent in and out (i.e., sent to the cutting position, and sent out after cutting for easy removal). In more detail, the two conveyor belts 17 can be conveyor belts or conveyor chains, and the second mounting frame 11 is also equipped with a second drive motor 21 for driving the conveyor belt 17. The two sides of the support plate 18 are placed on the corresponding two conveyor belts 17. As the second drive motor 21 runs, the support plate 18 can be driven to move by the conveyor belt 17, thereby conveying the stator 8.

[0034] like Figure 1-5 As shown, in a more detailed exemplary scheme, the first shaping portion 5 includes a plurality of first clamping plates 23 stacked at intervals, and the second shaping portion 6 includes a plurality of second clamping plates 24 staggered with the first clamping plates 23. The first clamping plates 23 and the second clamping plates 24 have opposing V-shaped openings, and the bottom of the V-shaped opening is an arc-shaped surface. The first clamping plates 23 and the second clamping plates 24 can be stacked with each other to enclose a shaping channel. A group (two) of stator wires 7 are limited in the shaping channel so that the stator wires 7 are in a vertical state during the cutting process to ensure the cutting accuracy. The setting of the V-shaped opening is equivalent to sandwiching the stator wire 7 in the middle after the V-shaped openings on both sides cross each other. The bottom surface of the V-shaped opening is an arc-shaped surface, which can better fit the outer wall of the stator wire 7, thereby ensuring that the stator wire 7 is in a vertical state.

[0035] Furthermore, the shearing mechanism further includes a first mounting block 25 and a second mounting block 26 for respectively fixing all the first clamping plates 23 and all the second clamping plates 24, the first mounting block 25 is elastically connected to the first moving block 1 in a transverse direction, and the second mounting block 26 is elastically connected to the second moving block 2 in a transverse direction, that is, a mounting base is provided for the first clamping plates 23 and the second clamping plates 24, respectively, and at the same time, the transverse elastic connection allows the first shaping portion 5 and the second shaping portion 6 to first clamp the stator wire 7 during the shearing process, and then continue to be sheared by the first shearing knife 3 and the second shearing knife 4, that is, shaping first and then cutting;

[0036] More specifically, the first mounting block 25 is fixedly connected with a first partition plate 27 located between two adjacent first clamping plates 23, and the second mounting block 26 is fixedly connected with a second partition plate 28 located between two adjacent second clamping plates 24. The shapes of the first partition plate 27 and the second partition plate 28 exactly match the V-shaped opening (can be accommodated in the corresponding V-shaped opening), thereby further supplementing the side gap of the shaping channel, making the shaping channel more complete.

[0037] like Figure 1-5 As shown, in a more detailed exemplary scheme, the first moving block 1 is also laterally telescopically connected to a first guide rod 29, and a first spring 30 is also arranged around the outside of the first guide rod 29 and is fixedly connected to the first moving block 1 and the first mounting block 25 respectively; the second moving block 2 is also laterally telescopically connected to a second guide rod 31, and a second spring 20 is also arranged around the outside of the second guide rod 31 and is fixedly connected to the second moving block 2 and the second mounting block 26 respectively, that is, during operation, the first moving block 1 and the second moving block 2 can first close the first shaping part 5 and the second shaping part 6 with the assistance of the first spring 30 and the second spring 20, and then continue to drive the first shearing knife 3 and the second shearing knife 4 to cut (during the process, the first spring 30 and the second spring 20 are compressed, and the first guide rod 29 and the second guide rod 31 extend into the corresponding first moving block 1 and the second moving block 2 (a sliding channel is arranged inside) to adapt to the continued movement of the first moving block 1 and the second moving block 2).

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
