[0046] The workbench 100 in the flat wire stator copper wire flaring device 000 can have a flaring position 101.

[0047] The plurality of flaring mechanisms 300 in the flat wire stator copper wire flaring device 000 are installed on the workbench 100 and can be arranged in an array around the flaring position 101, and the plurality of flaring mechanisms 300 can flare the stator copper wire on the stator clamping tool 200 located at the flaring position 101.

[0048] The stator clamping tool 200 in the flat wire stator copper wire flaring device 000 can include a first driving component 201, two sliding supports 202, and two clamping components 203. The two sliding supports 202 can be oppositely arranged along the extension direction of the first driving component 201 and are in driving connection with the first driving component 201. The two clamping components 203 can be respectively located on the side of the two sliding supports 202 away from the first driving component 201, and the clamping component 203 can be detachably connected with the corresponding sliding support 202. The two clamping components 203 can be used to enclose a containing space for installing the flat wire stator A (the flat wire stator is used to carry the stator copper wire), and the outer side of the flat wire stator A can have a first positioning piece A1, and the clamping component 203 can have a second positioning piece A2 matched with the first positioning piece A1.

[0049] The first driving component 201 can be configured to drive the two sliding supports 202 to slide towards or away from each other along the extension direction of the first driving component 201, so as to drive the two clamping components 203 to slide towards or away from each other along the extension direction of the first driving component 201.

[0050] In the case that the flat wire stator copper wire flaring device 000 further includes the lifting mechanism 400, the rotating mechanism 500, and the insulation paper protection mechanism 600, the lifting mechanism 400 can be installed on the workbench 100, and the rotating mechanism 500 can be in fastening connection with the lifting mechanism 400 and the stator clamping tool 200 respectively. The rotating mechanism 500 can be configured to drive the stator clamping tool 200 to rotate at the flaring position 101, and the lifting mechanism 400 can be configured to drive the rotating mechanism 500 and the stator clamping tool 200 to lift simultaneously. The insulation paper protection mechanism 600 can be installed on the workbench 100 and arranged side by side with the corresponding flaring mechanism 300.

[0051] For example, the flaring of the stator copper wire by the flat wire stator copper wire flaring device 000 is illustratively described herein:

[0052] Firstly, the flat wire stator A needs to be fed, the lifting mechanism 400, the rotating mechanism 500 and the stator clamping tool 200 are pushed to the manual feeding position of the workbench 100, the appropriate clamping part 203 is selected according to the specification of the flared flat wire stator A, the flat wire stator A to be flared is placed between the two clamping parts 203 in the stator clamping tool 200, and the first positioning piece A1 and the second positioning piece A2 are positioned to complete the first positioning of the flat wire stator A; then, the first driving part 201 drives the sliding support 202 to move, thereby driving the clamping part 203 to tightly fit and clamp the outer ring of the flat wire stator A, and the second positioning of the flat wire stator A feeding is completed.

[0053] Then, the flat wire stator A is flared, the rotating mechanism 500, the stator clamping tool 200 and the flat wire stator A to be flared are lifted to a predetermined height by the lifting mechanism 400, the height difference between the insulation paper tooth protection mechanism 600 and the flared jaw in the flared mechanism 300 is adjusted to meet the flaring needs, and the insulation paper tooth protection mechanism 600 abuts against the insulation paper outside the copper wire, that is, the flaring operation can be performed; then, after a plurality of flared mechanisms 300 complete a flaring action, the insulation paper protection mechanism 600 retreats away from the flat wire stator A, the rotating mechanism 500, the stator clamping tool 200 and the flat wire stator A are lowered to a safe position by the lifting mechanism 400, and the rotating mechanism 500 drives the stator clamping tool 200 and the flat wire stator A to rotate by a certain angle (the angle depends on the slot number of the flat wire stator); then, the rotating mechanism 500, the stator clamping tool 200 and the flat wire stator A to be flared are lifted to a predetermined height again by the lifting mechanism 400, and the height difference between the insulation paper tooth protection mechanism 600 and the flared jaw in the flared mechanism 300 is adjusted to meet the flaring needs, that is, the flaring operation can be performed again; finally, the above steps are sequentially cycled to complete the flaring operation of all the flat wire stator copper wires.

[0054] Optionally, please refer to Figure 2 and Figure 4 , Figure 4Figure 1 is a partial structural schematic diagram of a copper wire flaring device for a flat wire stator according to an embodiment of the present application. The first driving component 201 can include a support 201a, a lead screw 201b, and two sliding blocks 201c. The lead screw 201b is rotationally connected to the support 201a, and the two sliding blocks 201c are each drivingly connected to the lead screw 201b. The two sliding blocks 201c are each fixedly connected to two sliding support members 202. In the process of rotating the lead screw 201b, the two sliding blocks 201c can move towards each other or away from each other along the extension direction of the lead screw 201b. For example, the two ends of the lead screw 201b can have external threads with different rotation directions, and the two sliding blocks 201c can have internal threads matched with the two segments of external threads.

[0055] In the embodiments of the present application, there are various optional implementation manners for the arrangement of the first positioning member A1 in the flat wire stator A and the second positioning member A2 arranged in the clamping component 203. The embodiments of the present application will be illustratively described by taking the following two optional implementation manners as examples.

[0056] The first implementation manner, please refer to Figure 5 , Figure 5 Figure 2 is a partial structural exploded schematic diagram of a copper wire flaring device for a flat wire stator according to an embodiment of the present application. The first positioning member A1 can be a positioning groove, and the second positioning member A2 can include a connecting hole A21 arranged on the clamping component 203 and communicated with the positioning groove, and a positioning pin A22. One end of the positioning pin A22 can pass through the connecting hole A21 in the clamping component 203 and extend into the positioning groove on the flat wire stator A. In this case, after the flat wire stator A is placed between the two clamping components 203, the positioning groove on the outer side surface of the flat wire stator A is aligned with the connecting hole A21 in the clamping component 203, and then one end of the positioning pin A22 is inserted into the positioning groove through the connecting hole A21 to complete the positioning of the flat wire stator A and the clamping component 203. At the same time, the cooperation of the positioning pin A22 and the positioning groove can also prevent the flat wire stator A from rotating adversely during the flaring process.

[0057] The second optional implementation manner, the first positioning member A1 can be a positioning groove, and the second positioning member A2 can be a positioning protrusion fixed on the side of the clamping component 203 facing the flat wire stator A, and the positioning protrusion can be matched with the positioning groove. In this case, by arranging the positioning protrusion on the inner side surface of the clamping component 203, the positioning protrusion can be inserted into the positioning groove after the positioning groove is aligned with the positioning protrusion during the installation of the flat wire stator A, to complete the assembly of the flat wire stator A.

[0058] Optionally, please refer to Figure 4 and Figure 6 , Figure 6is another partial structure explosion schematic view of the flat wire stator copper wire flaring device provided in the embodiment of the present application. Each sliding support 202 in the stator clamping tool 200 can include an adjusting piece 2021 and a transition connecting piece 2022. The adjusting piece 2021 can be in transmission connection with the first driving part 201, and the transition connecting piece 2022 can be connected with the adjusting piece 2021 and the clamping part 203 respectively. Here, the transition connecting piece 2022 can be detachably connected with the adjusting piece 2021, and the transition connecting piece 2022 can be detachably connected with the clamping part 203. For example, the transition connecting piece 2022 can be detachably connected with the clamping part 203 through screw connection or clamping. It should be noted that, in the case where the first driving part 201 includes a support 201a, a lead screw 201b and two sliding blocks 201c, the two sliding blocks 201c can be fastened with the two adjusting pieces 2021 respectively.

[0059] In the present application, as shown in Figure 6 , the adjusting piece 2021 in the sliding support 202 can have a plurality of rows of adjusting holes a1 arranged in an array. The arrangement direction of the plurality of rows of adjusting holes a1 can be parallel to the extension direction of the first driving part 201. The transition connecting piece 2022 can be fastened with one row of adjusting holes a1 in the plurality of rows of adjusting holes a1 through a connecting column (not shown in the figure). In this case, by arranging the plurality of rows of adjusting holes a1 in the adjusting piece 2021 in parallel to the extension direction of the first driving part 201, the transition connecting piece 2022 can be connected with adjusting holes a1 in different rows through connecting columns to adjust the position of the transition connecting piece 2022 on the adjusting piece 2021, thereby driving the clamping part 203 to realize position adjustment. That is, on the basis of the position adjustment of the clamping part 203 driven by the first driving part 201 through the sliding support 202, the secondary position adjustment function of the clamping part 203 is realized through the cooperation of the transition connecting piece 2022 and the adjusting piece 2021. It should be noted that the position adjustment of the clamping part 203 is to realize the clamping or loosening of the flat wire stator A through the clamping part 203.

[0060] For example, the number of each row of adjusting holes a1 in the adjusting piece 2021 can be one or more. When the number of each row of adjusting holes a1 is more than one, the transition connecting piece 2022 can be fastened with a plurality of adjusting holes a1 in one row of adjusting holes a1 through a plurality of connecting columns.

[0061] In the embodiment of the present application, please refer to Figure 7 and Figure 8 , Figure 7 is another partial structure schematic view of the flat wire stator copper wire flaring device provided in the embodiment of the present application, Figure 8 is Figure 7A local enlarged schematic view of the flaring mechanism 300. Each flaring jaw 301 can have a flaring jaw 301. In the case that the flat wire stator copper wire flaring device 000 includes a plurality of insulation paper protection mechanisms 600, the insulation paper protection mechanism 600 can have a second driving component 601, a connecting plate 602, a guide column 603, a floating plate 604, and a spiral spring 605. The second driving component 601 can be in driving connection with the connecting plate 602. The first end of the guide column 603 can be fastened to the end of the connecting plate 602. One end of the floating plate 604 can be sleeved on the guide column 603 and in sliding connection with the guide column 603. The end of the floating plate 604 away from the guide column 603 can have an insulation paper tooth guard 604a arranged opposite to the flaring jaw 301. The spiral spring 605 can be sleeved on the guide column 603 and distributed between the floating plate 604 and the second end of the guide column 603. The second driving component 601 can be configured to drive the floating plate 604 to move along the direction of approaching the flaring position 101 or moving away from the flaring position 101 through the connecting plate 602. For example, when the second driving component 601 drives the floating plate 604 to move along the direction of approaching the flaring position 101 through the connecting plate 602, the clamping groove of the insulation paper tooth guard 604a is completely in close contact with the outside of the copper wire insulation paper.

[0062] For example, during the process of flaring the stator copper wire by the flaring jaw 301 of the flaring mechanism 300, in order to ensure the stability of the copper wire flaring, the lifting mechanism 400 needs to drive the stator clamping tool 200 and the flat wire stator A to rise a certain distance for position compensation while flaring. At this time, in order to prevent the insulation paper tooth guard 604a in contact with the stator copper wire from damaging the insulation paper, during the process of the stator copper wire rising with the stator clamping tool 200, the insulation paper tooth guard 604a can also have a certain rising trend due to the friction between the stator copper wire and the insulation paper tooth guard 604a. Here, since the spiral spring 605 is arranged between the floating plate 604 and the second end of the guide column 603, when the floating plate 604 provided with the insulation paper tooth guard 604a has a rising movement trend, the floating plate 604 can generate a certain rising stroke by compressing the spiral spring 605 to match the rising stroke of the stator copper wire, so as to avoid the flat wire insulation paper tooth guard 604a from damaging the stator copper wire.

[0063] Optionally, please refer to Figure 9 , Figure 9is another structure schematic view of the flat wire stator copper wire flaring device provided by the embodiment of the present application. The workbench 100 can have a strip-shaped sliding rail 102, and the lifting mechanism 400 can have a mounting fixed plate 401 in sliding connection with the strip-shaped sliding rail 102. Wherein, the lifting mechanism 400 can be moved into the flaring position 101 through the cooperation of the mounting fixed plate 401 and the strip-shaped sliding rail 102, or the lifting mechanism 400 can be moved out of the flaring position 101 through the cooperation of the mounting fixed plate 401 and the strip-shaped sliding rail 102. Here, the lifting mechanism has a lifting column 402 penetrating through the mounting fixed plate 401, and the end of the lifting column 402 is connected with the bottom of the rotating mechanism 500, and the lifting of the lifting column 402 drives the lifting of the rotating mechanism 500 and the stator clamping tool 200.

[0064] In the embodiment of the present application, as shown in Figure 9 The tooling table 100 can also have a driving member 103 and a telescopic rod 104, the driving member 103 can have a containing cavity (not shown in the figure), and part of the telescopic rod 104 can be located in the containing cavity of the driving member 103. Wherein, the telescopic rod 104 can be configured to be telescopic in the containing cavity of the driving member 103, so as to drive the mounting fixed plate 401 to move along the extension direction of the strip-shaped sliding rail 102 through the end located outside the containing cavity. In this case, the telescopic rod 104 is driven to be telescopic by the driving member 103, so as to control the movement of the mounting fixed plate 401 in the lifting mechanism 400 on the strip-shaped sliding rail 102, thereby realizing the circulating movement of the lifting mechanism 400, the rotating mechanism 500 and the stator clamping tool 200 between the flaring position 101 and the stator manual feeding position.

[0065] In the embodiment of the present application, as shown in Figure 9 The number of flaring mechanisms 300 in the flat wire stator copper wire flaring device 000 is three, and the included angle between every two adjacent flaring mechanisms 300 among the three flaring mechanisms 300 can be 120 degrees. In this way, the flaring requirements of the stators with all existing slot numbers (36 slots, 48 slots, 54 slots, 72 slots, etc.) can be met, the flaring mechanism replacement is simple, the three flaring mechanisms 300 perform flaring operation at the same time through the servo control mechanism (not shown in the figure), the working efficiency is high, and the motion consistency is high. Here, the three flaring mechanisms 300 are controlled at the same time through the servo control mechanism, so as to complete a flaring operation at the same time.

[0066] For example, as shown in Figure 7 and Figure 8As shown, each flaring mechanism 300 can include a support frame 302, a flaring drive module 303, a mounting plate 304, a flaring jaw cylinder 305, a support block 306, a line abutting stopper 307 and a flaring jaw 301.

It should be noted that the line abutting stopper 307 can be in abutment with the end of the copper wire to reserve a straight section at the end of the copper wire.
