[0025] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, Y-axis, and Z-axis. The direction along the X-axis is vertical, the direction along the Y-axis is horizontal, and the direction along the Z-axis is vertical. The X-axis and Y-axis are two mutually perpendicular coordinate axes on the same horizontal plane, and the Z-axis is the vertical coordinate axis.

[0026] Please see Figure 1 and Figure 2The wire cutting device provided in this application embodiment will now be described. This wire cutting device is used to cut the coil 20 on the stator 10. The coil 20 includes an inner wire row 201 and an outer wire row 202 located outside the inner wire row 201. The inner wire row 201 includes multiple inner wire ends 2011, which are arranged in a ring around the stator 10. The outer wire row 202 includes multiple outer wire ends 2021, which are also arranged in a ring around the stator 10. The multiple inner wire ends 2011 are respectively aligned with the multiple outer wire ends 2021 radially around the stator 10. The wire cutting device includes a machine base 1, a rotary support 2, a rotary drive assembly 3, a wire cutting support 4, a cutter body 5, a cutter lateral movement assembly 6, and a cutter lifting assembly 7. The rotary support 2 is rotatably mounted on the machine base 1 and is used to support the stator 10. The stator 10 is placed on the rotating support 2 in an inverted orientation, meaning that both the inner wire row 201 and the outer wire row 202 on the stator 10 face downwards. (See reference...) Figure 3 The rotary drive assembly 3 is mounted on the machine base 1. The output end of the rotary drive assembly 3 is connected to the rotary support 2. The rotary drive assembly 3 drives the rotary support 2 to rotate, which in turn drives the stator 10 to rotate. (See reference...) Figure 4 and Figure 5The tangent support base 4 has an inner wire hole 41, an outer wire hole 42, and a tangent channel 43. The inner wire hole 41 is for the inner wire head 2011 to pass through, the outer wire hole 42 is for the corresponding outer wire head 2021 to pass through, and the tangent channel 43 is used to connect the inner wire hole 41 and the outer wire hole 42. Both the inner wire hole 41 and the outer wire hole 42 are arranged in an outward V-shape to facilitate the insertion of the inner wire head 2011 into the inner wire hole 41 and the outer wire head 2021 into the outer wire hole 42. One end of the cutter body 5 is connected to the cutter traverse assembly 6, and the other end of the cutter body 5 extends into the tangent channel 43. The cutter traverse assembly 6 is mounted on the tangent support base 4, and its output end is connected to the end of the cutter body 5 extending out of the tangent channel 43. The cutter traverse assembly 6 drives the cutter body 5 to reciprocate along the X-axis through the inner wire hole 41 and the outer wire hole 42. The cutter lifting assembly 7 is installed on the machine base 1. The output end of the cutter lifting assembly 7 is connected to the tangent support base 4. The cutter lifting assembly 7 is used to drive the tangent support base 4 to lift along the Z-axis. This structure allows the cutting support 4 to be raised and lowered via the cutting blade lifting assembly 7, thereby enabling the corresponding inner wire head 2011 and outer wire head 2021 on the stator 10 to be inserted into the inner wire hole 41 and outer wire hole 42 respectively. The cutting blade lateral movement assembly 6 drives the cutting blade body 5 to reciprocate in the cutting channel 43, allowing the cutting blade body 5 to simultaneously cut the corresponding inner wire head 2011 and outer wire head 2021, thus ensuring that the lengths of the inner wire head 2011 and outer wire head 2021 remain consistent. The rotating support 2 provides support for the stator 10. The rotating drive assembly 3 drives the rotating support 2 to rotate, allowing each inner wire head 2011 and corresponding outer wire head 2021 to be inserted into the inner wire hole 41 and outer wire hole 42 respectively. By repeating the above cutting action, the rotational cutting operation of the inner wire row 201 and outer wire row 202 can be achieved, thereby improving the cutting efficiency.

[0027] In one embodiment, see Figure 2 and Figure 3 As a specific embodiment of the tangent device provided in this application, the rotating support base 2 includes a rotating disk 21 rotatably mounted on the machine base 1 and multiple support bases 22 mounted on the rotating disk 21. The output end of the rotating drive assembly 3 is connected to the rotating disk 21. A wire clamping seat 30 is mounted on the stator 10, and a wire clamping positioning hole 301 is provided on the wire clamping seat 30. A support guide rod 23 for inserting into the wire clamping positioning hole 301 is mounted on the support base 22. In this structure, the stator 10 can be supported by multiple support bases 22; the alignment and installation accuracy between the stator 10 and the rotating support base 2 can be achieved by the alignment and cooperation between the support guide rod 23 and the wire clamping positioning hole 301, and the rotation of the stator 10 relative to the rotating support base 2 can also be prevented.

[0028] In one embodiment, see Figure 3A ball bearing 11 is installed on the machine base 1. The outer ring of the ball bearing 11 is fixedly mounted on the machine base 1, and the inner ring of the ball bearing 11 is connected and fixed to the center position of the rotating disk 21. With this structure, the rotating disk 21 can be rotated on the machine base 1 through the ball bearing 11, which can reduce the friction and wear of the rotating disk 21 and thus protect the rotation of the rotating disk 21.

[0029] In one embodiment, see Figure 2 and Figure 3 The number of clamping positioning holes 301 can be multiple, and the multiple clamping positioning holes 301 are arranged in a circumferential ring array along the stator 10. Multiple support bases 22 are arranged in a circumferential ring array along the rotating disk 21. Each support base 22 can be equipped with a support guide rod 23. The multiple support guide rods 23 can be inserted into the multiple clamping positioning holes 301 respectively, so as to improve the installation accuracy of the stator 10 on the rotating support 2, and also prevent the stator 10 from rotating relative to the rotating support 2 during the rotation of the rotating support 2.

[0030] In one embodiment, see Figure 3 As a specific embodiment of the tangent device provided in this application, the outer periphery of the rotating disk 21 is provided with a plurality of rotating teeth 211; the rotating drive assembly 3 includes a rotating drive component 31 mounted on the machine base 1 and a rotating drive gear 32 mounted on the output end of the rotating drive component 31, the rotating drive gear 32 meshing with the rotating teeth 211. The rotating drive component 31 can be a motor, and the rotating drive gear 32 can be mounted on the output shaft of the motor. In this structure, the rotating drive component 31 can drive the rotating drive gear 32 to rotate, thereby driving the rotating disk 21 and the stator 10 to rotate together, thus allowing for rotational adjustment of the positions of the inner wire row 201 and the outer wire row 202 on the stator 10.

[0031] Optionally, the rotary drive assembly 3 may also be a drive motor directly connected to the rotary disk 21; or, the rotary drive assembly 3 may also be a belt drive mechanism that drives the rotary disk 21 to rotate via a belt.

[0032] In one embodiment, see Figure 1 , Figure 4 and Figure 8As a specific embodiment of the tangent device provided in this application, the tangent support base 4 includes a tangent base 44 connected to the output end of the cutter lifting assembly 7, a tangent sliding seat 45 slidably mounted on the tangent base 44, a tangent base 46 mounted on the tangent sliding seat 45, and a tangent power unit 47 for driving the tangent sliding seat 45 to reciprocate. The tangent power unit 47 is mounted on the tangent base 44 and connected to the tangent sliding seat 45. The tangent base 46 is provided with an inner wire hole 41, an outer wire hole 42, and a tangent channel 43. The sliding direction of the tangent sliding seat 45 is the same as the sliding direction of the cutter body 5. The tangent power unit 47 can be a cylinder / electric cylinder / screw drive mechanism, a linear motor, etc. In this embodiment, the tangent power unit 47 adopts a screw drive mechanism. In this structure, after the stator 10 is moved onto the rotating support 2, the tangential power unit 47 drives the tangential sliding seat 45 and the tangential base 46 to approach the stator 10 along the X-axis, so that the inner wire row 201 and the outer wire row 202 are located directly below the inner wire hole 41 and the outer wire hole 42, respectively. Subsequently, the cutter lifting assembly 7 drives the tangential support 4 to rise along the Z-axis, so that the inner wire head 2011 and the outer wire head 2021 are inserted into the inner wire hole 41 and the outer wire hole 42, respectively. Finally, the cutter lateral movement assembly 6 drives the cutter body 5 to extend along the X-axis, and the cutter body 5 can cut the inner wire head 2011 and the outer wire head 2021 simultaneously.

[0033] In one embodiment, see Figure 4 and Figure 8 The tangent sliding seat 45 is slidably mounted on the tangent base 44 via guide rail pairs. There are two guide rail pairs, each mounted at one end of the tangent base 44, extending along the X-axis. This structure improves the reliability of the tangent sliding seat 45's reciprocating movement on the tangent base 44 through the guide rail pairs.

[0034] In one embodiment, see Figure 4 and Figure 8 Two tangent sensors 441 are respectively installed on the tangent base 44, and the two tangent sensors 441 are spaced apart along the X-axis. A tangent sensing plate 451 is installed on the tangent sliding seat 45, and the tangent sensing plate 451 can be disposed between the two tangent sensors 441. In this structure, by sensing the two tangent sensors 441 in cooperation with the tangent sensing plate 451, the movement stroke of the tangent sliding seat 45 along the X-axis can be limited, thereby limiting the displacement of the inner wire hole 41 and the outer wire hole 42 in the X-axis direction.

[0035] In one embodiment, see Figures 4 to 6As a specific embodiment of the wire cutting device provided in this application, the wire cutting base 46 is further provided with a material passage 461, which is connected to the inner wire hole 41, the outer wire hole 42 and the wire cutting channel 43 respectively; the wire cutting support base 4 also includes a wire cutting guide base 48 installed on the wire cutting base 46, which is provided with a material guide channel 481, which is connected to the material passage 461. The inner wire hole 41 and the outer wire hole 42 are both located at the top of the wire cutting base 46; the wire cutting channel 43 extends along the X-axis; the material passage 461 is located below the wire cutting channel 43; the material guide channel 481 is located below the material passage 461 and extends along the Z-axis. With this structure, the wire ends cut by the cutter body 5 can be discharged sequentially through the material passage 461 and the material guide channel 481.

[0036] Optionally, a waste bin is installed on the machine base 1, located directly below the wire feeding seat 48. With this structure, the wire scraps drawn out through the feeding channel 481 can fall into the waste bin for storage.

[0037] In one embodiment, see Figure 3 As a specific embodiment of the tangent device provided in this application, the machine base 1 has a first clearance notch 12 for the tangent base 46 to extend into; the tangent device also includes a rotating base 8 for supporting the rotating support 2. The rotating base 8 is mounted on the machine base 1 and located between the machine base 1 and the rotating support 2. The rotating base 8 has a second clearance notch 81 that communicates with the first clearance notch 12. With this structure, the rotating base 8 can support the rotating support 2, preventing the normal rotation of the rotating support 2 from being affected by the excessive weight of the stator 10. The first clearance notch 12 and the second clearance notch 81 can allow the tangent base 46 to be accommodated, and the tangent base 46 can extend into the first clearance notch 12 and the second clearance notch 81 to perform tangent operations on the inner wire row 201 and the outer wire row 202.

[0038] In one embodiment, see Figure 3 The rotating base 8 has a circular structure, and a second clearance notch 81 is provided at one end of the rotating base 8 near the tangent base 46. The rotating base 8 and the machine base 1 can be detachably connected by fasteners such as screws and bolts, which facilitates the assembly and disassembly of the rotating base 8.

[0039] Optionally, a plurality of ball bearings are mounted on the rotating base 8, arranged in a circumferential ring array along the rotating base 8. Each ball bearing is rotatably mounted on the rotating base 8, extending beyond the top of the rotating base 8, and the top of each ball bearing can contact the bottom of the rotating support 2. This structure, through the multiple ball bearings, achieves rolling friction between the rotating support 2 and the rotating base 8, thereby reducing frictional wear between the rotating support 2 and the rotating base 8.

[0040] In one embodiment, see Figure 3 As a specific embodiment of the tangent device provided in this application, the rotating disk 21 is disposed between the rotating drive gear 32 and the first clearance notch 12. The rotating disk 21 has a semi-circular structure and has a straight segment 212 and an arc segment 213. The arc segment 213 is positioned directly opposite the rotating drive gear 32, and the straight segment 212 is positioned directly opposite the first clearance notch 12. In this structure, since the inner wire row 201 and outer wire row 202 on the stator 10 have a fan-shaped structure, by setting the rotating disk 21 to a semi-circular structure, on the one hand, the manufacturing cost of the rotating disk 21 is reduced; on the other hand, the position of the hollow part of the rotating disk 21 can reserve sufficient tangent space for the inner wire row 201 and outer wire row 202.

[0041] In one embodiment, see Figure 3 The number of support bases 22 can be three, arranged in a circumferential ring array along the rotating disk 21. The two outer support bases 22 are spaced apart along the length of the straight segment 212, meaning that support bases 22 are installed at both ends of the straight segment 212. The middle support base 22 is located between the two outer support bases 22, meaning that the distance between the middle support base 22 and the two outer support bases 22 is the same. Thus, the three support bases 22 are arranged in an isosceles triangle to improve the support stability of the stator 10.

[0042] Optionally, the rotation angle of the rotating disk 21 is 0-90°, and the angle between the inner wire row 201 and the outer wire row 202 arranged in a fan shape is 30°-120°. The rotation of the rotating disk 21 can drive the stator 10 to rotate, and can also limit the rotation angle of the stator 10.

[0043] In one embodiment, see Figure 2 and Figure 3The clamping seat 30 may include an upper clamping ring 302 sleeved on the stator 10 and a lower clamping ring 303 connected to the upper clamping ring 302. The upper clamping ring 302 has a circular ring structure, and the lower clamping ring 303 has a semi-circular ring structure. The tops of the three support bases 22 can respectively abut against the bottom of the upper clamping ring 302 to support the stator 10. Support supports 221 are respectively installed on the two outer support bases 22. The two support supports 221 can respectively support both ends of the lower clamping ring 303 to improve the support and positioning effect of the stator 10 and the clamping seat 30. Moreover, the two outer support bases 22 can abut against both ends of the lower clamping ring 303 to prevent the stator 10 from rotating relative to the rotation support 2.

[0044] In one embodiment, see Figure 1 A protective cover 13 is installed on the machine base 1. The protective cover 13 can cover the rotary drive gear 32 and the rotary disk 21, thereby achieving the purpose of covering and protecting them.

[0045] In one embodiment, see Figure 1 The machine tool 1 is also equipped with a detector 16, which is positioned to point towards the tangent support 4. This structure allows the detector 16 to detect whether the tangent support 4 has moved to the correct position, thus facilitating the issuance of instructions for subsequent tangent operations.

[0046] In one embodiment, see Figure 4 As a specific embodiment of the tangent device provided in this application, the cutter lateral movement assembly 6 includes a lateral movement screw 61 rotatably mounted on the tangent support base 4, a lateral movement nut 62 mounted on the lateral movement screw 61, a lateral movement sliding seat 63 mounted on the lateral movement nut 62, and a lateral movement drive member 64 for driving the lateral movement screw 61 to rotate. The lateral movement drive member 64 is mounted on the tangent support base 4 and connected to the lateral movement screw 61. One end of the cutter body 5 is connected to the lateral movement sliding seat 63, and the other end of the cutter body 5 extends into the tangent channel 43. The lateral movement drive member 64 can be a motor. In this structure, the lateral movement screw 61 is driven to rotate in both directions by the lateral movement drive member 64, which in turn drives the lateral movement sliding seat 63 to slide back and forth along the X-axis, thereby driving the cutter body 5 to move back and forth in the tangent channel 43 to achieve the reciprocating tangent operation of the cutter body 5.

[0047] In one embodiment, see Figure 4 Two guide rail pairs are installed at intervals on the tangent support 4. Each guide rail pair extends along the X-axis. The two ends of the transverse sliding seat 63 are respectively installed on the two guide rail pairs to improve the reliability of the transverse sliding seat 63 reciprocating on the tangent support 4.

[0048] In one embodiment, see Figure 4The tangent support 4 has two transverse movement sensors 49 spaced apart along the X-axis. A transverse movement sensing plate 631 is mounted on the transverse movement slide 63, positioned between the two transverse movement sensors 49. This structure, through the sensing interaction between the transverse movement sensing plate 631 and the two transverse movement sensors 49, limits the movement of the transverse movement slide 63 along the X-axis, thereby limiting the movement of the cutter body 5 along the X-axis.

[0049] In one embodiment, see Figure 4 and Figure 7 As a specific embodiment of the tangent device provided in this application, the cutter body 5 includes a cutter connector 51 and a cutter working body 52. ​​One end of the cutter connector 51 is detachably connected to the transverse sliding seat 63, and the other end of the cutter connector 51 is detachably connected to one end of the cutter working body 52. ​​The other end of the cutter working body 52 extends into the tangent channel 43, and the end of the cutter working body 52 extending into the tangent channel 43 has a downward-sloping cutter bevel 522. This structure, by setting the cutter body 5 as a cutter connector 51 and a cutter working body 52, facilitates the assembly and disassembly of the cutter body 5, thereby enabling maintenance and replacement of the cutter body 5. By providing a cutter bevel 522 at the front end of the cutter working body 52, the sharpness of the cut can be improved.

[0050] In one embodiment, see Figure 4 and Figure 7 The transverse sliding seat 63 has a transverse mounting groove 632, which is T-shaped. One end of the cutter connector 51 has a first cutter engaging part 511 that extends into the transverse mounting groove 632, which is also T-shaped. By aligning and engaging the first cutter engaging part 511 with the transverse mounting groove 632, the disassembly efficiency of the cutter connector 51 and the transverse sliding seat 63 can be improved.

[0051] In one embodiment, see Figure 4 A transverse sliding seat 63 is equipped with a transverse sliding cover plate 633, which is located directly above the transverse sliding mounting groove 632. The transverse sliding cover plate 633 can confine the first cutter locking part 511 within the transverse sliding mounting groove 632.

[0052] In one embodiment, see Figure 7The cutter connector 51 has a second cutter engaging portion 512 at its end away from the transverse sliding seat 63; one end of the cutter working body 52 has a cutter mounting groove 521 for the second cutter engaging portion 512 to be inserted into. This structure, through the engaging engagement of the second cutter engaging portion 512 with the cutter mounting groove 521, improves the efficiency of assembling and disassembling the cutter connector 51 and the cutter working body 52. ​​The other end of the cutter working body 52 has a cutter bevel 522, meaning the thickness of the end of the cutter working body 52 gradually increases from the cutter bevel 522 towards the cutter mounting groove 521.

[0053] In one embodiment, see Figure 8 As a specific embodiment of the tangent device provided in this application, the cutter lifting assembly 7 includes a cutter lifting support plate 71, a cutter lifting guide rod 72 connecting the cutter lifting support plate 71 and the tangent support seat 4, a cutter lifting screw 73 rotatably mounted on the machine base 1, a cutter lifting nut 74 mounted on the cutter lifting screw 73, and a cutter lifting power unit 75 for driving the cutter lifting screw 73 to rotate. The cutter lifting nut 74 is mounted on the machine base 1, and the cutter lifting power unit 75 is mounted on the cutter lifting support plate 71 and connected to the cutter lifting screw 73. In this structure, the cutter lifting screw 73 is driven to rotate forward and backward by the cutter lifting power unit 75, which in turn drives the tangent support seat 4 to reciprocate up and down along the Z-axis, thereby adjusting the distance between the tangent base 46 and the coil 20.

[0054] In one embodiment, see Figure 8 The cutter lifting power unit 75 includes a cutter lifting motor 751 mounted on the cutter lifting support plate 71, a cutter lifting drive wheel 752 mounted on the output shaft of the cutter lifting motor 751, a cutter lifting driven wheel 753 mounted on the cutter lifting screw 73, and a cutter connecting belt 754 connecting the cutter lifting drive wheel 752 and the cutter lifting driven wheel 753. With this structure, the cutter lifting motor 751 can drive the cutter lifting screw 73 to rotate in both directions via the cutter connecting belt 754, thus improving the overall output efficiency of the cutter lifting assembly 7.

[0055] In one embodiment, see Figure 8 A lifting sensor plate 711 is installed on the cutting blade lifting support plate 71. Two lifting sensors 14 are installed at intervals along the Z-axis on the machine base 1. The lifting sensor plate 711 can be located between the two lifting sensors 14. With this structure, the lifting stroke of the tangent support base 4 along the Z-axis can be limited by the sensing cooperation between the lifting sensor plate 711 and the two lifting sensors 14.

[0056] In one embodiment, see Figure 8The cutter lifting assembly 7 also includes multiple cutter lifting drive units 76 mounted on the machine base 1. These multiple cutter lifting drive units 76 are divided into two groups, with the two groups located on opposite sides below the tangent support base 4. Each cutter lifting drive unit 76 can be an electric cylinder, pneumatic cylinder, etc. This structure allows the two groups of cutter lifting drive units 76 to push against both ends of the tangent support base 4, thereby improving the reliability of the tangent support base 4's lifting and lowering along the Z-axis.

[0057] In one embodiment, see Figure 1 The machine tool 1 has a third clearance notch 15, which is connected to the first clearance notch 12. This structure allows for the lifting and lowering of the tangential support 4 along the Z-axis direction via the third clearance notch 15.

[0058] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
