Description

Technical Field

[0001] The invention relates to the technical field of motor stator manufacturing, in particular to a stator wire cutting device. Background Art

[0002] Combination Figure 1 The stator 10 of the motor is the stationary part of the motor, and the stator 10 includes a stator core 11 and a stator winding 12. The stator winding 12 is wound on the stator core 11, and the stator winding 12 is formed by passing a stator wire 13 through the stator core 11 and then through a winding process. The stator wire 13 can be a flat wire, such as a flat copper wire.

[0003] When the motor is running, the current will generate a magnetic field in the stator winding 12, which will cause the stator wire 13 to vibrate, thereby generating noise. In order to reduce this vibration and noise, the stator wires 13 of the flat wire motor are of different lengths, so that the vibration frequency of each stator wire 13 is different, thereby reducing motor vibration and noise.

[0004] Therefore, the lengths of some radial stator wires 13 on the central axis are consistent, and the lengths of some radial stator wires 13 on the central axis are inconsistent, with the inner stator wires 13 being short and the outer stator wires 13 being long. For example, the lengths of the stator wires 13 in the radial direction A are consistent and shorter; the lengths of the stator wires 13 in the radial direction B are inconsistent, with the inner stator wires 13 being short and the outer stator wires 13 being long.

[0005] Therefore, after the winding process, the stator wire 13 needs to be cut flat to achieve that the radial length of part of the stator wire 13 is consistent and the radial length of part of the inner and outer lengths are inconsistent. In the related art, it is necessary to cut out the stator wire 13 with consistent radial length in the first station, cut out the stator wire 13 with inconsistent radial length in the inner part of the stator wire 13 in the second station, and cut out the stator wire 13 with inconsistent radial length in the outer part of the stator wire 13 in the third station. The related art has the technical problem of low efficiency in cutting the stator wire flat. Summary of the invention

[0006] The object of the present invention is to provide a stator wire cutting device, aiming to solve the technical problem of low stator wire cutting efficiency in the related art.

[0007] The present application provides a stator wire cutting device, the stator wire cutting device comprising:

[0008] A base plate, wherein the middle portion of the base plate has a first receiving hole penetrating the base plate along the thickness direction of the base plate;

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] Please refer to Figure 3 and Figure 4 This embodiment provides a stator wire cutting device. The stator wire cutting device includes a base plate 100, a first cutting assembly 200 and a second cutting assembly 300. The middle part of the base plate 100 has a first receiving hole 101 that penetrates the base plate 100 along the thickness direction Z of the base plate 100.

[0044] Combination Figure 5 The first cutting assembly 200 is mounted on the base plate 100 . The first cutting assembly 200 is provided with a first cutter 201 . The first cutter 201 is configured to slide in the first receiving hole 101 along the radial direction of the first receiving hole 101 .

[0045] Combination Figure 6 The second cutting assembly 300 and the first cutting assembly 200 are spaced apart along the circumference of the first receiving hole 101, the second cutting assembly 300 is installed on the base plate 100, the second cutting assembly 300 is provided with a second cutter 301 and a third cutter 302, the second cutter 301 and the third cutter 302 are spaced apart in the thickness direction Z of the base plate 100, and the second cutter 301 and the third cutter 302 are configured to slide in the first receiving hole 101 along the radial direction of the first receiving hole 101.

[0046] When the stator wire cutting device provided by the present embodiment is used, at a cutting station, the stator wire cutting device is fixedly installed at the cutting station, for example, the base plate 100 is fixedly installed at the cutting station, the stator 10 to be cut is moved to align with the stator wire cutting device, and the stator wire 13 extends into the first accommodating hole 101, or the stator 10 to be cut is fixed at the cutting station, the stator wire cutting device is moved manually or by a robot to align with the stator 10, and the stator wire 13 extends into the first accommodating hole 101. Next, the first cutter 201 slides in the first receiving hole 101 along the radial direction of the first receiving hole 101, cutting a portion of the radial stator wire 13, so that the length of the portion of the stator wire 13 is consistent, and the second cutter 301 and the third cutter 302 slide in the first receiving hole 101 along the radial direction of the first receiving hole 101, cutting another portion of the radial stator wire 13. Since the second cutter 301 and the third cutter 302 are spaced apart in the thickness direction Z of the base plate 100, the radial stator wire 13 of the portion is shorter on the inside and longer on the outside. In this way, the stator wire 13 can be cut flat at one cutting station, without cutting at three stations in turn, thereby improving the production efficiency of the stator 10.

[0047] In this application, it is assumed that the number of radial rows that need to have the same length is C, for example Figure 1The radial direction A in the figure is a row, the number of radial rows cut by a first cutting assembly 200 each time is D, the number of first cutting assemblies 200 is N, N is a positive integer, and can be one or more than two. If C>N*D, after all the first cutting assemblies 200 cut the stator wire 13 once, the stator 10 or the stator wire cutting device can be rotated around the thickness direction Z of the base plate 100, and then the stator wires 13 that need to be consistent in length in the remaining radial direction can be cut. In other words, the number of first cutting assemblies 200 can be the same as the number of radial rows of stator wires 13 that need to be consistent in length on the stator 10, or it can be different, and the number of first cutting assemblies 200 is at least one. If C=N*D, the first cutting assembly 200 slides and cuts once, and the cutting operation of all stator wires 13 that need to be consistent in length is completed. If C>N*D, by adjusting the orientation of the stator wire cutting device and / or the stator 10, the first cutting assembly 200 slides and cuts multiple times, and the cutting operation of the stator 10 is completed.

[0048] Optionally, each first cutting assembly 200 cuts one radial row each time, the number of first cutting assemblies 200 is the same as the number of radial rows of stator wires 13 on the stator 10 that require consistent lengths, there are multiple first cutting assemblies 200, and the multiple first cutting assemblies 200 are arranged in the radial distribution order of the stator wires 13 with consistent lengths, so that the first cutting assembly 200 slides and cuts once, completing the cutting operation of all stator wires 13 that require consistent lengths.

[0049] Similarly, the number of the second cutting assembly 300 is at least one, and may be one or more than two. If the number of the second cutting assembly 300 is small, the second cutting assembly 300 can slide and cut multiple times by adjusting the stator wire flattening device and / or the orientation of the stator 10, thus completing the flattening operation of the stator 10.

[0050] Optionally, each second cutting assembly 300 cuts one radial row each time, the number of second cutting assemblies 300 is the same as the number of radial rows of stator wires 13 of inconsistent lengths required on the stator 10, the number of second cutting assemblies 300 is multiple, and the multiple second cutting assemblies 300 are arranged in the radial distribution order of the stator wires 13 of inconsistent lengths.

[0051] In any of the above embodiments, the number of the first cutting assemblies 200 and the number of the second cutting assemblies 300 may be unequal or equal. Specifically, the number of radial rows that need to have consistent lengths is the first integer multiple E of the number of the first cutting assemblies 200, and the number of radial rows that need to have inconsistent lengths is the second integer multiple F of the number of the second cutting assemblies 300. If the first integer multiple and the second integer multiple F are the same, then by rotating the stator wire flattening device and / or the stator 10 E-1 times, the first cutting assembly 200 and the second cutting assembly 300 synchronously cut E times, and the flattening operation of all stator wires 13 can be completed.

[0052] Optionally, in the projection of the thickness direction Z of the base plate 100, the first cutting assembly 200 and the second cutting assembly 300 are arranged adjacent to each other to form a sector, which can be a circle at most. The central angle of the sector is 360° / E, and the first cutting assembly 200 and the second cutting assembly 300 rotate 360° / E each time, and rotate E-1 times to cover the entire circle, that is, complete the cutting operation of all stator wires 13.

[0053] In any of the above embodiments, the second cutter 301 and the third cutter 302 may have different radial distances from each other in the first receiving hole 101 , or may have the same radial distances from each other.

[0054] For example, the second cutter 301 and the third cutter 302 are driven by their respective driving mechanisms to slide in the radial direction of the first receiving hole 101, so the radial distance between the second cutter 301 and the third cutter 302 can be the same. During cutting, the sliding distances of the second cutter 301 and the third cutter are controlled to be different by their respective driving mechanisms, so that the stator wire 13 on the inner side is cut by one of the second cutter 301 and the third cutter 302, and the stator wire 13 on the outer side is cut by the other of the second cutter 301 and the third cutter 302.

[0055] For example, the radial distances between the second cutter 301 and the third cutter 302 in the first receiving hole 101 are different, and the second cutter 301 and the third cutter 302 slide synchronously. No matter the second cutter 301 is closer to the inner side of the first receiving hole 101 than the third cutter 302, or the second cutter 301 is closer to the outer side of the first receiving hole 101 than the third cutter 302, as long as the stator core 11 is closer to the inner cutter in the thickness direction Z of the base plate 100 when the stator 10 is aligned with the stator wire cutting device, the stator wire 13 on the inner side will be shorter after being cut by the inner cutter, and the stator wire 13 on the outer side will be longer after being cut by the outer cutter. Figure 1 and Figure 6For illustration, the second cutter 301 is closer to the inside than the third cutter 302, and the second cutter 301 is closer to the negative direction of the Z direction than the third cutter 302, and the stator core 11 is located in the negative direction of the Z direction. Then, when the second cutting assembly 300 slides radially from the inside to the outside, the second cutter 301 cuts the stator wire 13 on the inside, so that the length of the stator wire 13 is short, and the third cutter 302 is closer to the outside and can cut the stator wire 13 on the outside, so that the length of the stator wire 13 on the outside is long. It can be understood that in other embodiments, assuming that the second cutter 301 is closer to the outside than the third cutter 302, and the second cutter 301 is closer to the positive direction of the Z direction than the third cutter 302, then Figure 1 After the stator 10 in the middle is inverted and aligned with the stator wire cutting device, it is also possible to achieve that the stator wire 13 on the inner side is short and the stator wire 13 on the outer side is long.

[0056] In some embodiments, one of the second cutter 301 and the third cutter 302 is located at the same position as the first cutter 201 in the thickness direction Z of the base plate 100. Specifically, the second cutter 301 is flush with the first cutter 201.

[0057] In one embodiment, in combination Figure 4 and Figure 5 The first cutting assembly 200 is configured to be slidably mounted on the base plate 100 along the radial direction of the first receiving hole 101, and the first cutter 201 slides in the first receiving hole 101 along the radial direction of the first receiving hole 101 along the first cutting assembly 200, so that the first cutter 201 does not need to be provided with a separate driving mechanism, and the first cutter 201 can be fixedly provided on the first cutting assembly 200 and move synchronously with the first cutting assembly 200. Compared with controlling the first cutter 201 to slide separately, controlling the first cutting assembly 200 to slide is more convenient to operate.

[0058] Combination Figure 4 and Figure 6 The second cutting assembly 300 is configured to be slidably mounted on the base plate 100 along the radial direction of the first receiving hole 101, and the second cutter 301 and the third cutter 302 are spaced apart along the radial direction of the first receiving hole 101. The second cutter 301 and the third cutter 302 slide in the first receiving hole 101 along the radial direction of the first receiving hole 101 along with the second cutting assembly 300. Compared with controlling the second cutter 301 and the third cutter 302 to slide separately, controlling the second cutting assembly 300 to slide drives the second cutter 301 and the third cutter 302 to slide synchronously, and the operation is simpler.

[0059] In one embodiment, in combination Figure 4 , Figures 7 to 10The base plate 100 includes a rotating plate 110 and a radial limiting plate 120. The rotating plate 110 is rotatably mounted on the radial limiting plate 120. The rotating plate 110 has a first limiting groove 111, which extends along the circumference of the first receiving hole 101. The first limiting groove 111 gradually approaches or gradually moves away from the first receiving hole 101 during the circumferential extension of the first receiving hole 101. The radial limiting plate 120 has a first radial groove 121 extending along the radial direction of the first receiving hole 101.

[0060] The first cutting assembly 200 is slidably disposed in the first radial groove 121, and the first cutting assembly 200 is provided with a first limiting portion 202, and the first limiting portion 202 is movably limited in the first limiting groove 111. The rotating disk 110 rotates, driving the first cutting assembly 200 to slide along the first radial groove 121 under the drive of the first limiting groove 111, so as to cut the stator wire 13.

[0061] The second cutting assembly 300 is slidably disposed in the first radial groove 121, and the second cutting assembly 300 is provided with a second limiting portion 303, and the second limiting portion 303 is movably limited in the first limiting groove 111. The rotating disk 110 rotates, driving the second cutting assembly 300 to slide along the first radial groove 121 under the drive of the first limiting groove 111, thereby cutting the stator wire 13.

[0062] In this way, the turntable 110 rotates, which can synchronously drive all the first cutting assemblies 200 and all the second cutting assemblies 300 to slide along the radial direction of the first receiving hole 101, thereby achieving high driving efficiency and simplifying driving control.

[0063] In this embodiment, the rotating disk 110 and the radial limiting disk 120 respectively have through holes along the thickness direction Z. The positions of the through holes correspond to each other and are combined to form a first receiving hole 101 .

[0064] Optionally, the first limiting portion 202 is a bearing, a ball or a slider, which is not specifically limited here.

[0065] Optionally, the second limiting portion 303 is a bearing, a ball or a slider, which is not specifically limited here.

[0066] In any of the above embodiments, please also refer to Figure 2The stator wire cutting device also includes a rotating drive member 710, which is connected to the turntable 110. The rotating drive member 710 is used to drive the turntable 110 to rotate to realize an automated cutting operation. The rotating drive member 710 can be arranged inside the base plate 100 or outside the base plate 100. It can be located in the projection of the turntable 110 in the thickness direction Z or outside the projection of the turntable 110 in the thickness direction Z. The rotating drive member 710 can be a rotating motor, a rotating cylinder or a rotating oil cylinder. The rotating drive member 710 can also output a linear motion, which is then converted into a rotational motion of the turntable 110 through a worm gear, a rack and pinion, a connecting rod mechanism, etc.

[0067] Optionally, a gear portion 114 is disposed on the side of the turntable 110 , and the rotation driving member 710 meshes with the gear portion 114 via a gear to drive the turntable 110 to rotate.

[0068] Optionally, the radial limiting disk 120 wraps the rotating disk 110 to protect the rotating disk 110 and other internal structures from running reliably. The radial limiting disk 120 has a notch 124 to enable the rotating driving member 710 located outside the radial limiting disk 120 to be drivingly connected to the rotating disk 110 .

[0069] In any of the above embodiments, please also refer to Figure 2 The stator wire cutting device further includes a protective tube 720, which is installed on the base plate 100 along the thickness direction Z of the base plate 100. The protective tube 720 is coaxially arranged with the first receiving hole 101, and the outer diameter of the protective tube 720 is greater than the inner diameter of the first receiving hole 101. The protective tube 720 can prevent the stator wire 13 from being exposed. Specifically, the protective tube 720 and the stator core 11 are located on opposite sides of the base plate 100 in the thickness direction Z.

[0070] In any of the above embodiments, please combine Figure 4 The first cutting assembly 200 is movably embedded in the first limiting groove 111 through the first limiting portion 202, and the first cutting assembly 200 is movably embedded in the first radial groove 121. The first cutting assembly 200 is limited between the radial limiting disk 120 and the rotating disk 110, so that the first cutting assembly 200 can slide reliably. Moreover, after the rotating disk 110 or the radial limiting disk 120 is disassembled, the first cutting assembly 200 can be easily assembled and disassembled. In this way, the staff can flexibly increase or decrease the first cutting assembly 200 according to the number of radial rows of stator wires 13 of different stators 10 with the same length, or even replace the radial limiting disk 120 to match the cutting requirements of various stators 10.

[0071] Similarly, the second cutting assembly 300 is movably embedded in the first limiting groove 111 through the second limiting portion 303, and the second cutting assembly 300 is movably embedded in the first radial groove 121. The first cutting assembly 200 is limited between the radial limiting disk 120 and the turntable 110, so that the second cutting assembly 300 can slide reliably. Moreover, the second cutting assembly 300 can be flexibly increased or decreased to match the cutting requirements of various stators 10.

[0072] In any of the above embodiments, please combine Figure 4 The second cutting assembly 300 and the first cutting assembly 200 may be located at the same position in the thickness direction Z of the base plate 100, for example, the first cutting assembly 200 and the second cutting assembly 300 are both located on the same side of the turntable 110. The first cutting assembly 200 and the second cutting assembly 300 may also be spaced apart in the thickness direction Z of the base plate 100, for example, the first cutting assembly 200 and the second cutting assembly 300 are respectively located on both sides of the turntable 110.

[0073] Specifically, the end of the first limiting groove 111 close to the first receiving hole 101 is closed to limit the sliding distance of the first cutting assembly 200 and the second cutting assembly 300 toward the inner side of the first receiving hole 101, thereby playing a limiting role.

[0074] Specifically, the end of the first limiting groove 111 away from the first receiving hole 101 is closed to limit the sliding distance of the first cutting assembly 200 and the second cutting assembly 300 toward the outside of the first receiving hole 101, thereby playing a limiting role.

[0075] Optionally, both ends of the first limiting groove 111 are closed, thereby limiting the sliding range of the first cutting assembly 200 and the second cutting assembly 300 in the radial direction of the first receiving hole 101. It can be understood that in some embodiments, one end of the first limiting groove 111 is closed and the other end is open, and the end close to the first receiving hole 101 can be closed and the end away from the first receiving hole 101 can be open, or the end close to the first receiving hole 101 can be open and the end away from the first receiving hole 101 can be closed. In other embodiments, both ends of the first limiting groove 111 are open.

[0076] Specifically, the first limiting groove 111 can be selected as a straight groove, an arc groove 601 or a spiral groove.

[0077] For example, the linear groove is not parallel or perpendicular to the radial direction of the first receiving hole 101, thereby driving the first cutting assembly 200 and the second cutting assembly 300 to slide in the first radial groove 121. It can be understood that in other embodiments, the shape of the first limiting groove 111 can also be other shapes, as long as the radial distance change of the first receiving hole 101 can be achieved, thereby driving the first cutting assembly 200 and the second cutting assembly 300 to change in the radial distance of the first receiving hole 101.

[0078] For another example, the first limiting groove 111 is a spiral groove, and the spiral groove surrounds the first receiving hole 101 for more than one circle. The length of the spiral groove is longer, and it can accommodate more first limiting portions 202 and second limiting portions 303, that is, the stator wire cutting device can be equipped with more first cutting components 200 and second cutting components 300, so as to reduce the number of cutting times of the first cutting components 200 and second cutting components 300 during the cutting operation of each stator 10. Even more, the number of first cutting components 200 can be the same as the number of radial rows with the same length, and the number of second cutting components 300 can be the same as the number of radial rows with inconsistent lengths, so that the stator wire cutting device can complete the cutting of all radial rows in one cutting operation, and there is no need to adjust the orientation of the stator wire cutting device and / or the stator 10.

[0079] Generally, the spiral groove surrounds the first receiving hole 101 for two to four turns. The radial positions of the first stopper 202 in the first cutting assemblies 200 can be different, so that the first stopper 202 is embedded in different positions in the spiral groove. The radial positions of the second stopper 303 in the second cutting assemblies 300 can be different, so that the second stopper 303 is embedded in different positions in the spiral groove.

[0080] In some embodiments, in combination Figure 7 and Figure 8 The first limiting groove 111 includes a first spiral groove 112 and a second spiral groove 113, and the first spiral groove 112 and the second spiral groove 113 are respectively arranged on the opposite sides of the turntable 110 in the thickness direction Z of the base plate 100. The radial limiting plate 120 includes a first limiting plate 122 and a second limiting plate 123, and the first limiting plate 122 and the second limiting plate 123 are respectively located on the opposite sides of the turntable 110 in the thickness direction Z of the base plate 100. The first cutting component 200 is slidably arranged in the first radial groove 121 of the first limiting plate 122, and the first limiting portion 202 is movably limited in the first spiral groove 112. The second cutting component 300 is slidably arranged in the first radial groove 121 of the second limiting plate 123, and the second limiting portion 303 is movably limited in the second spiral groove 113.

[0081] The first cutting assembly 200 and the second cutting assembly 300 are respectively installed on both sides of the turntable 110, making full use of the space on both sides of the turntable 110, thereby avoiding interference between the first cutting assembly 200 and the second cutting assembly 300 or insufficient installation space.

[0082] In this embodiment, the first spiral groove 112 and the second spiral groove 113 are respectively provided on both sides of the turntable 110, which increases the total length of the first limiting groove 111, can accommodate more first cutting assemblies 200 and second cutting assemblies 300, and can be suitable for cutting operations of stators 10 with more slots.

[0083] Optionally, the second limiting plate 123 covers the rotating plate 110 and the first limiting plate 122 , and the second limiting plate 123 has a notch 124 for driving connection between the rotating plate 110 and an external rotating driving member 710 .

[0084] In one embodiment, in combination Figure 4 , Figure 5 and Fig. 9 , a fourth radial groove 1221 is provided at a partial groove bottom of the first radial groove 121 of the first limiting plate 122. The fourth radial groove 1221 may penetrate the first limiting plate 122, or may not penetrate the first radial plate. The fourth radial groove 1221 extends in the radial direction of the first receiving hole 101. The fourth radial groove 1221 is in communication with the first receiving hole 101, and the end of the fourth radial groove 1221 away from the first receiving hole 101 forms a first limiting wall 1222. The first cutting assembly 200 is provided with a third limiting portion 203, and the third limiting portion 203 is slidably disposed in the fourth radial groove 1221. The third limiting portion 203 can abut against the first limiting wall 1222, thereby limiting the maximum distance that the first cutting assembly 200 slides in the radial direction of the first receiving hole 101 in a direction away from the first receiving hole 101, thereby achieving a limiting effect.

[0085] In one embodiment, in combination Figure 7 and Figure 8 , the spiral direction of the first spiral groove 112 is the same as the spiral direction of the second spiral groove 113. In this way, when the turntable 110 rotates in one direction, if it rotates clockwise when viewed from one side of the turntable 110, then it rotates counterclockwise when viewed from the other side of the turntable 110, so that the sliding directions of the first cutting assembly 200 and the second cutting assembly 300 are opposite. For example, the first cutting assembly 200 slides from the outside to the inside along the radial direction of the first receiving hole 101, and the second cutting assembly 300 slides from the inside to the outside along the radial direction of the first receiving hole 101.

[0086] Thus, for the stator 10, part of the radial stator wire 13 is cut from the inside to the outside, and part of the radial stator wire 13 is cut from the outside to the inside, the acting forces are opposite, and the forces are relatively stable, which is conducive to the stability of the stator 10 during the cutting process. For the stator wire cutting device, the rotating disk 110 rotates, the first cutting assembly 200 and the second cutting assembly 300 move in opposite directions, and the center of gravity is relatively stable, which is conducive to the stable operation of the stator wire cutting device.

[0087] In one embodiment, in combination Fig.11 , Fig.12 and Fig. 20 The base plate 100 further includes a wire drum 130, which is installed on the side of the first limiting plate 122 or the second limiting plate 123 away from the rotating plate 110, and the wire drum 130 has a second wire groove 131 for the stator wire 13 to pass through. The stator wire 13 enters the interior of the rotating plate 110 through the second wire groove 131, and the second wire groove 131 is used to realize the alignment between the stator 10 and the stator wire cutting device. In addition, the second wire groove 131 can also ensure that the position of the stator wire 13 is relatively stable when the first cutting assembly 200 and the second cutting assembly 300 cut the stator wire 13, so as to facilitate the stable cutting operation.

[0088] exist Fig.12 In the illustrated embodiment, the wire drum 130 is located on a side of the first limiting disk 122 away from the rotating disk 110. The wire drum 130 is mounted on the first limiting disk 122.

[0089] Optionally, one end of the second wire slot 131 away from the rotating disk 110 is provided with a chamfer to facilitate guiding the stator wire 13 into the second wire slot 131 .

[0090] In one embodiment, in combination Figures 13 to 17 The stator wire cutting device further includes a first support block 400, which is fixedly mounted on at least one of the first limiting plate 122 and the second limiting plate 123. For example, the first support block 400 is fixedly mounted on the first limiting plate 122, or fixedly mounted on the second limiting plate 123, or simultaneously mounted on the first limiting plate 122 and the second limiting plate 123. The first support block 400 is located between the first limiting plate 122 and the second limiting plate 123, and the first support block 400 is located in the first receiving hole 101. The middle part of the first support block 400 has a second receiving hole 401 that penetrates the first support block 400 along the thickness direction Z of the base plate 100, and the first support block 400 is provided with a through knife groove 402 that is connected to the second receiving hole 401, and the through knife groove 402 extends along the radial direction of the first receiving hole 101.

[0091] The number of through knife grooves 402 is the same as that of the second cutting assembly 300, and the positions are corresponding, so that the end of the second cutting assembly 300 extends to between the rotating disk 110 and the first limiting disk 122 through the through knife grooves 402, and the second cutter 301 and the third cutter 302 are installed at the end of the second cutting assembly 300. In this way, the second cutting assembly 300, whose main body is located on one side of the rotating disk 110, extends to the other side of the rotating disk 110 through the through knife grooves 402, so that the second cutter 301 and the third cutter 302 can cut the stator wire 13 on the other side of the rotating disk 110. Among them, the through knife grooves 402 can guide and limit the end of the second cutting assembly 300, further improving the sliding stability of the second cutting assembly 300.

[0092] When the length of the stator wire 13 with a uniform radial length requirement is the same as or has a small difference with the length of the part of the stator wire 13 with an inconsistent radial length requirement, the second cutter 301 can be substantially flush with the first cutter 201 in the thickness direction Z through the through cutter groove 402, thereby meeting the length processing requirement of the stator wire 13.

[0093] Specifically, the second cutting assembly 300 includes a mounting rod 305 extending along the thickness direction Z of the base plate 100 , and a second cutter 301 and a third cutter 302 spaced apart are mounted at the end of the mounting rod 305 .

[0094] It can be understood that in other embodiments, the first cutting assembly 200 extends to the other side of the rotating disk 110 through the through knife groove 402, instead of the second cutting assembly 300 extending to the other side of the rotating disk 110 through the through knife groove 402. Specifically, the number of through knife grooves 402 is the same as the number of the first cutting assembly 200, and the positions are corresponding. The end of the first cutting assembly 200 extends to between the rotating disk 110 and the second limiting disk 123 through the through knife groove 402, and the first cutter 201 is installed at the end of the first cutting assembly 200, so that the first cutter 201 can cut the stator wire 13 on the other side of the rotating disk 110. Among them, the through knife groove 402 can guide and limit the end of the first cutting assembly 200, further improving the sliding stability of the second cutting assembly 300.

[0095] Specifically, the end surface of the first support block 400 is provided with a second radial groove 403, and the second radial groove 403 extends in the radial direction of the first receiving hole 101. One of the through knife groove 402 and the second radial groove 403 is used to guide the sliding of the first cutting assembly 200, and the other of the through knife groove 402 and the second radial groove 403 is used to guide the sliding of the second cutting assembly 300. In this way, the first cutting assembly 200 and the second cutting assembly 300 can not only be limited in the first radial groove 121, but also can stably cut the stator wire 13 in the radial direction of the first receiving hole 101 under the limitation of the through knife groove 402 or the second radial groove 403.

[0096] When the through knife groove 402 is used for the second cutting assembly 300 to extend to the other side of the rotating disk 110, the through knife groove 402 is used to guide the second cutting assembly 300 to slide, and the second radial groove 403 is used to guide the first cutting assembly 200 to slide. When the through knife groove 402 is used for the first cutting assembly 200 to extend to the other side of the rotating disk 110, the through knife groove 402 is used to guide the first cutting assembly 200 to slide, and the second radial groove 403 is used to guide the second cutting assembly 300 to slide.

[0097] Optionally, combined Fig.16 and Fig.17 The first support block 400 is provided with partition blocks 404 spaced apart along the circumference of the second receiving hole 401, and the interval between two adjacent partition blocks 404 forms a through-cutting groove 402. The partition block 404 has a first wire groove 405 penetrating the partition block 404 along the thickness direction Z of the base plate 100, and the first wire groove 405 is used to guide the stator wire 13 to pass through and limit the stator wire 13, so as to facilitate the stable cutting of the first cutting assembly 200. Among them, the number of rows of the first wire groove 405 is the same as the number of radial rows of the stator wire 13 with the same length requirement, and the first wire groove 405 accommodates the part of the stator wire 13.

[0098] Furthermore, the first cutter 201 cuts the stator wire 13 along the end of the partition block 404, that is, the partition block 404 also controls the cutting position of the stator wire 13, and cooperates with the first cutter 201 to limit the cutting position of the first cutter 201 in the thickness direction Z of the base plate 100.

[0099] Furthermore, a chamfer is provided at one end of the first wire slot 405 away from the rotating disk 110 to enlarge the outer diameter of the entrance of the first wire slot 405 so that the stator wire 13 can smoothly enter the first wire slot 405 .

[0100] Optionally, a first stopper 406 is provided at the end of the partition block 404 near the first cutter 201 in the thickness direction Z of the base plate 100. The first stopper 406 is located on the side of the partition block 404 near the second accommodating hole 401, so that the first cutter 201 slides along the second radial groove 403 and the partition block 404 to cut the stator wire 13 until it abuts against the first stopper 406. The first stopper 406 limits the sliding distance of the first cutter 201 to ensure that the feeding distance of the first cutter 201 is stable and reliable.

[0101] Furthermore, a first knife stopping groove 407 is provided on one side of the first stop block 406 facing the second radial groove 403 for accommodating the first cutter 201, so that the first cutter 201 slides along the second radial groove 403 into the first knife stopping groove 407, and the three circumferential sides of the first cutter 201 are restricted within the first knife stopping groove 407, thereby further improving the limiting effect on the first cutter 201.

[0102] Optionally, the first support block 400 is provided with a second stopper 408, and the second stopper 408 is located in the extending direction of the through knife groove 402. The second cutting assembly 300 cuts the stator wire 13 along the setting direction of the through knife groove 402 until the third cutter 302 abuts against the second stopper 408, and the second stopper 408 limits the sliding distance of the third cutter 302 to ensure that the feeding distance of the third cutter 302 and the second cutting assembly 300 is stable and reliable.

[0103] Furthermore, a second knife stopping groove 409 is formed on one side of the second stop block 408 toward the through knife groove 402 for accommodating the third cutter 302, so that the third cutter 302 slides along the through knife groove 402 into the second knife stopping groove 409, and the three circumferential sides of the third cutter 302 are restricted within the second knife stopping groove 409, thereby further improving the limiting effect on the third cutter 302.

[0104] For details, please refer to Fig.14 and Fig.18 The stator wire flattening device also includes an isolation block 500. The isolation block 500 is installed on the through knife groove 402. The isolation block 500 has a first wire accommodating groove 501 that penetrates the isolation block 500 along the thickness direction Z of the base plate 100. The through knife groove 402 is used to guide the second cutting assembly 300 to slide. The second cutter 301 is located between the isolation block 500 and the first limiting plate 122. The third cutter 302 is located between the isolation block 500 and the second limiting plate 123. The third cutter 302 is closer to the side wall of the first accommodating hole 101 than the second cutter 301, that is, the third cutter 302 is closer to the outside of the first accommodating hole 101. The third cutter 302 cuts the stator wire 13 exposed from the isolation block 500, so as to classify and locate the stator wire 13 to be cut, and prevent the third cutter 302 from cutting the wrong stator wire 13. At the same time, the isolation block 500 separates the second cutter 301 and the third cutter 302 in the thickness direction Z of the base plate 100 to ensure that the lengths of the stator wires 13 cut by the two are different, thereby meeting the requirement of inconsistent lengths of some radial stator wires 13.

[0105] Optionally, the third cutter 302 slides against the end of the isolation block 500, that is, the isolation block 500 provides sliding support for the third cutter 302, while also guiding the third cutter 302 to cut the stator wire 13, thereby ensuring that the third cutter 302 can accurately cut the stator wire 13 in the thickness direction Z of the base plate 100.

[0106] Optionally, one end of the first wire accommodating groove 501 away from the second limiting plate 123 is provided with a chamfer to enlarge the outer diameter of the entrance of the first wire accommodating groove 501 so as to facilitate the stator wire 13 to smoothly enter the first wire accommodating groove 501 .

[0107] Optionally, the isolation block 500 is connected, clamped, bonded or integrally formed in the through knife groove 402 via fasteners.

[0108] In one embodiment, see Fig.13 , Fig.14 and Fig.19 The stator wire cutting device further includes a second support block 600. The second support block 600 is fixedly mounted on the radial limiting disk 120, and is located in the first receiving hole 101. The outer peripheral wall of the second support block 600 is provided with a plurality of rotation support portions 770 distributed at intervals along the circumference of the first receiving hole 101, and the rotation support portions 770 are used to roll in contact with the rotating disk 110 to rotationally support the rotating disk 110 and reduce the rotation resistance of the rotating disk 110.

[0109] Specifically, the end surface of the second support block 600 in the thickness direction Z of the base is provided with a third radial groove 602, the third radial groove 602 extends in the radial direction of the first receiving hole 101, and the first cutting assembly 200 and / or the second cutting assembly 300 are slidably disposed in the first radial groove 121 and the third radial groove 602 on both sides of the base in the thickness direction Z. The third radial groove 602 increases the sliding support for the first cutting assembly 200 and / or the second cutting assembly 300, and improves the sliding stability and reliability of the first cutting assembly 200 and / or the second cutting assembly 300.

[0110] For example, the number of radial limit plates 120 is one, the number of third radial grooves 602 is equal to or greater than the sum of the number of first cutting assemblies 200 and second cutting assemblies 300, one end of the first cutting assembly 200 and the second cutting assembly 300 is slidably supported in the first radial groove 121, and the other end extends into the first accommodating hole 101 and is supported in the third radial groove 602 of the second support block 600 located in the first accommodating hole 101.

[0111] For example, there are two radial limiting disks 120, namely, a first limiting disk 122 and a second limiting disk 123, which are respectively located on both sides of the rotating disk 110, and one end of the second supporting block 600 is fixedly connected to at least one of the first limiting disk 122 and the second limiting disk 123, that is, the second supporting block 600 can be fixedly connected to the first limiting disk 122, can also be fixedly connected to the second limiting disk 123, and can also be simultaneously connected to the first limiting disk 122 and the second limiting disk 123. The end of the second supporting block 600 is provided with a third radial groove 602, and the second supporting block 600 can be provided with the third radial groove 602 at one end. The third radial groove 602 can be located at the end close to the first limiting disk 122, so as to be used for sliding cooperation with the first cutting assembly 200. The third radial groove 602 can also be located at the end close to the second limiting disk 123, so as to be used for sliding cooperation with the second cutting assembly 300. Of course, the second support block 600 may also be provided with the third radial groove 602 at both ends, so as to achieve sliding cooperation with the first cutting assembly 200 and the second cutting assembly 300 at both ends. The end of the second support block 600 used for connecting with the radial limiting plate 120 and the end provided with the third radial groove 602 may be the same end or not, which is not limited here.

[0112] Optionally, the outer peripheral wall of the second support block 600 is provided with a plurality of arcuate grooves 601 spaced apart along the circumference of the first receiving hole 101. The number of the arcuate grooves 601 is greater than or equal to the number of the rotation support parts 770. In other words, each arcuate groove 601 is equipped with a rotation support part 770, so that the number of the arcuate grooves 601 is the same as the number of the rotation support parts 770. Alternatively, a rotation support part 770 is equipped in some of the arcuate grooves 601, and a rotation support part 770 is not equipped in another part of the arcuate grooves 601, so that the number of the arcuate grooves 601 is greater than the number of the rotation support parts 770.

[0113] Optionally, the rotation support portion 770 is a bearing or a ball.

[0114] Specifically, the second cutting assembly 300 is provided with a fourth limiting portion 304. The fourth limiting portion 304 can abut against the hole wall of the third receiving hole 603. When the second cutting assembly 300 slides from the inside to the outside along the radial direction of the first receiving hole 101 until the fourth limiting portion 304 abuts against the hole wall of the third receiving hole 603, the sliding distance of the second cutting assembly 300 is limited.

[0115] Furthermore, the fourth limiting portion 304 is mounted on the mounting rod 305 of the second cutting assembly 300 .

[0116] Specifically, the first support block 400 and the second support block 600 are arranged at intervals along the thickness direction Z of the base plate 100. Optionally, the first support block 400 is arranged closer to the first limiting plate 122 than the second support block 600, and the second support block 600 is arranged closer to the second limiting plate 123 than the first support block 400. Optionally, the first support block 400 and the second support block 600 are in contact with each other, or even fixedly connected to each other.

[0117] In some embodiments, in combination Figure 4 The stator wire cutting device provided in this embodiment further includes a first limit plate 730, one end of which is mounted on the end surface of the first limit plate 122 away from the second limit plate 123, and the other end of the first limit plate 730 extends into the first receiving hole 101, and is used to support the first cutting assembly 200 extending into the first receiving hole 101. The first limit plate 730 does not extend to the second support block 600, and will not affect the stator wire 13 entering and exiting the first receiving hole 101. Optionally, the number of the first limit plates 730 is one or more than two. The more than two first limit plates 730 are spaced apart along the circumference of the first receiving hole 101.

[0118] Specifically, the stator wire cutting device further includes a second limiting plate 740, which is fan-shaped, and both ends of the second limiting plate 740 are connected to the first limiting plate 730 to close the exposed portion of the first limiting plate 122. The projection of the second limiting plate 740 in the thickness direction Z of the base does not overlap with the first receiving hole 101, and will not affect the stator wire 13 from entering and exiting the first receiving hole 101.

[0119] In some embodiments, in combination Figure 4 The stator wire cutting device also includes a first limiting ring 750, which is fixedly installed on the outer edge of the turntable 110 and is located between the turntable 110 and the second cutting assembly 300, and is in plane contact with the second cutting assembly 300 to avoid the turntable 110 having an uneven surface due to the second spiral groove 113, thereby increasing the sliding resistance between the turntable 110 and the second cutting assembly 300.

[0120] In some embodiments, in combination Figure 4 The stator wire cutting device also includes a second limiting ring 760, which is fixedly installed on the inner edge of the turntable 110 and is located between the turntable 110 and the second cutting assembly 300, and is in plane contact with the second cutting assembly 300 to avoid the turntable 110 having an uneven surface due to the second spiral groove 113, thereby increasing the sliding resistance between the turntable 110 and the second cutting assembly 300.
