Description

Technical Field

[0001] This invention belongs to the field of machine tool technology, specifically relating to a device for cutting pipes, and more particularly to a stator winding cutting device and its working method. Background Technology

[0002] In the stator winding process of motors, a certain length of copper wire is reserved after winding, which is usually cut manually. However, manual cutting has a large error and cannot guarantee that the length of the copper wire is consistent after cutting; at the same time, manual cutting of a single stator winding is time-consuming and cannot keep up with the pace of automated production lines.

[0003] In related technologies, to facilitate the insertion of copper wire into the limiting hole of the cutting station, the diameter of the limiting hole is designed to be larger than the diameter of the copper wire. Therefore, during the actual cutting process, the copper wire is prone to radial movement within the limiting hole, resulting in increased fluctuation in the length of the copper wire after cutting. At the same time, when the cutting blade cuts into the copper wire, the radial movement of the copper wire generates an axial component force, which causes the copper wire to be pulled and moved axially, resulting in the technical problem of cut position deviation.

[0004] Therefore, it is essential to develop a stator winding cutting device and its working method to solve the above-mentioned technical problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Summary of the Invention

[0006] This disclosure provides at least one stator winding cutting device and its working method.

[0007] In a first aspect, embodiments of this disclosure provide a stator winding cutting device, comprising:

[0008] In one alternative implementation, a support platform, located above the worktable, is provided with several cutting stations;

[0009] A limiting fixture, installed at the cutting station, is used to limit the copper wire to be cut, including:

[0010] Positioning plates, two of which are arranged opposite each other, and a positioning hole is provided at their inner ends;

[0011] Limiting plates, the two limiting plates are arranged opposite to each other and their horizontal movement direction is opposite to that of the positioning plate;

[0012] The stator is fixed to the support platform, and each copper wire moves downward and is inserted into the corresponding cutting station.

[0013] When the copper wire is inserted between the two limiting plates, it pushes the two positioning plates to slide outward synchronously. The two positioning plates are adapted to clamp and limit the axial movement of the copper wire.

[0014] When the positioning plate slides outward, it drives the limiting plate to slide inward until the side wall of the limiting plate abuts against the outer wall of the copper wire, thereby limiting the radial movement of the copper wire.

[0015] In one optional embodiment, the positioning hole is semi-circular, and the opening size gradually decreases along the thickness direction;

[0016] In this process, the copper wire moves downwards and presses against the sidewall of the positioning hole, thereby pushing the two positioning plates to move apart.

[0017] In one optional embodiment, the sidewalls of the positioning plate and the limiting plate are provided with linear toothed racks facing each other;

[0018] The cutting station is located between two linear racks and is equipped with a rotatable transmission gear; the transmission gear meshes with both linear racks simultaneously.

[0019] The linear rack on the positioning plate side moves outward, driving the transmission gear to rotate, and the transmission gear drives the linear rack on the limiting plate side to move inward.

[0020] In one optional embodiment, a drive disk is rotatably mounted on the operating table, and a plurality of drive components adapted to the cutting station are slidably mounted on the drive disk, with a cutting blade at the end of each drive component.

[0021] When the drive disc rotates, it drives the drive component to move radially so that the cutting blade passes over the cutting station to cut the copper wire.

[0022] In one optional embodiment, a support ring is provided on the operating table. The support ring is located outside the drive disk and its horizontal height is not less than the horizontal height of the drive disk.

[0023] In one alternative implementation, the drive element includes:

[0024] A fixing block is mounted on the support ring;

[0025] A drive rod extends radially along the drive disc and slides through the fixed block;

[0026] The cutting blade is located below the cutting station;

[0027] When the drive disc rotates, it drives the drive rod to slide radially, and the cutting blade passes over the cutting station to cut the copper wire.

[0028] In one optional embodiment, a spiral groove is formed on the upper surface of the drive disk, and a driven roller adapted to the spiral groove is rotatably provided on the bottom wall of the drive rod.

[0029] When the drive disc rotates in the forward direction, the spiral groove sidewall drives the driven roller to move the drive rod radially inward.

[0030] When the drive disc rotates in the opposite direction, the sidewall of the spiral groove drives the driven roller to move the drive rod radially outward.

[0031] In one optional embodiment, the support platform is provided with a plurality of limiting grooves along the radial direction, each limiting groove corresponding to a cutting blade, and the cutting blade is adapted to slide radially within the limiting groove.

[0032] In one alternative implementation, the support platform is provided with a plurality of vision sensors adapted to the cutting station.

[0033] The limiting plate is located outside the vision sensor;

[0034] When the copper wire is not inserted into the cutting station, the two limiting plates retract into the cutting station, and the vision sensor is adapted to detect whether the copper wire is inserted.

[0035] After the copper wire is clamped and limited by two positioning plates, the two positioning plates move towards each other and block the upper part of the vision sensor. The vision sensor is suitable for detecting whether the lower end of the copper wire protrudes from the cutting station.

[0036] In one alternative embodiment, a collection hopper is provided on the bottom wall of the operating table, located below the cutting station, for collecting the cut copper wires.

[0037] Secondly, this disclosure also provides a method for operating a stator winding cutting device, the method comprising:

[0038] After the stator is fixed on the support platform, each copper wire moves downward and is inserted into the corresponding cutting station;

[0039] When the copper wire is inserted between the two limiting plates, it pushes the two positioning plates to slide outward synchronously. The two positioning plates are adapted to clamp and limit the axial movement of the copper wire.

[0040] When the positioning plate slides outward, it drives the limiting plate to slide inward until the side wall of the limiting plate abuts against the outer wall of the copper wire, thereby limiting the radial movement of the copper wire.

[0041] The beneficial effects of this invention are that it provides a stator winding cutting device and its working method. By setting a limiting fixture, when the copper wire is inserted into the cutting station, the copper wire pushes the two positioning plates to move apart until the lower end of the copper wire protrudes from the bottom wall of the cutting station. The two positioning plates clamp the copper wire from both sides to perform axial limiting. At the same time, the two limiting plates move towards each other until the side wall abuts against the outer wall of the copper wire to radially limit the copper wire and prevent the copper wire from moving radially when the cutting blade cuts the copper wire.

[0063] Research has shown that the precision of copper wire cutting in the stator winding process directly affects motor performance (such as resistance balance and temperature rise stability).

[0064] In related technologies, to facilitate the insertion of copper wire into the limiting hole of the cutting station, the diameter of the limiting hole is often designed to be larger than the diameter of the copper wire. Therefore, during the actual cutting process, the copper wire is prone to radial movement within the limiting hole, resulting in increased fluctuations in the length of the copper wire after cutting. At the same time, when the cutting blade cuts into the copper wire, the radial movement of the copper wire generates an axial component force, which causes the copper wire to be pulled and moved axially, resulting in a technical problem of cut position deviation.

[0065] Therefore, it is essential to develop a stator winding cutting device and its working method to solve the above-mentioned technical problems.

[0066] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.

[0067] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0068] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0069] like Figures 1 to 6 As shown, at least one embodiment provides a stator winding cutting device, comprising:

[0070] A support platform 1, located above the operating platform 2, has several cutting stations 3 evenly distributed around its circumference. Each cutting station 3 has a cutting hole 30, and both the positioning plate 41 and the limiting plate 42 are slidably disposed within the cutting hole 30. In the initial state, the positioning plate 41 is pushed out of the side wall of the cutting hole 30 by the compression spring 32, and the ends of the two positioning plates 41 abut against each other. At this time, the two limiting plates 42 are respectively retracted within the cutting station 3. After the stator 6 is fixed on the support platform 1, each copper wire 60 of the stator 6 passes through the cutting hole 30 and extends downward. The cutting blade 50 slides horizontally along the bottom wall of the cutting station 3 to cut off the excess portion of the copper wire 60 protruding from the bottom wall of the cutting station 3.

[0071] Reference Appendix Figure 4 A limiting fixture 4, slidably disposed within the cutting hole 30 of the cutting station 3, is used to limit the copper wire 60 to be cut. It includes: a positioning plate 41, with two positioning plates 41 arranged opposite each other, and each having a positioning hole 43 at its inner end; the positioning hole 43 is semi-circular; a compression spring 32 is disposed at one end of each positioning plate 41 away from the positioning hole 43, and the other end of the compression spring 32 is located within the cutting station 3; the compression spring 32 is used to push the positioning plate 41 to move towards the axis of the cutting hole 30. A limiting plate 42, with two limiting plates 42 arranged opposite each other and moving in the opposite direction to the horizontal movement of the positioning plates 41; the limiting plate 42 is parallel to the positioning plates 41, and its horizontal movement direction is opposite to that of the positioning plates 41; the limiting plate 42 is located on the side of the limiting plate 42 away from the cutting blade 50. After the stator 6 is fixed to the support platform 1, each copper wire 60 moves downward and inserts into the corresponding cutting hole 30. When the copper wire 60 is inserted between the two limiting plates 42, it pushes the two positioning plates 41 to slide outward synchronously. The two positioning plates 41 are adapted to clamp and limit the axial movement of the copper wire 60. When the positioning plates 41 slide outward, they drive the limiting plates 42 to slide inward through the transmission teeth 44 until the side wall of the limiting plate 42 abuts against the outer wall of the copper wire 60, thereby limiting the radial movement of the copper wire 60. At this time, the two sides of the copper wire 60 are clamped and limited by the two positioning plates 41 to prevent axial displacement of the copper wire 60 when it is cut. The side wall of the positioning plate 41 abuts against the outer wall of the copper wire 60 to prevent the copper wire 60 from moving radially, especially in the direction of the cutting blade 50, when the cutting blade 50 cuts the copper wire 60, thus ensuring the flatness of the cut surface when the copper wire 60 is cut.

[0072] Reference Appendix Figure 4 The positioning hole 43 is semi-circular, and its opening size gradually decreases from the top surface to the bottom surface along the thickness direction. The positioning hole 43 is also conical, with its opening size gradually decreasing from the top surface to the bottom, so that the copper wire 60 can be inserted into the positioning hole 43. As the copper wire 60 is inserted, it pushes the positioning plate 41 outward. Specifically, the downward movement of the copper wire 60 presses against the sidewall of the positioning hole 43, thereby pushing the two positioning plates 41 apart. Figure 4In the middle, the limit plate 42 in the dotted line state is telescopically set in the cutting station 3, and the horizontal height and thickness of the limit plate 42 are the same as those of the positioning plate 41.

[0073] Reference Appendix Figure 5 The positioning plate 41 and the limiting plate 42 have straight racks 45 arranged opposite to each other on their sidewalls; the cutting station 3 is rotatably arranged with a transmission gear 44 between the two straight racks 45; the transmission gear 44 meshes with the two straight racks 45 simultaneously; wherein, the straight racks 45 on the side of the positioning plate 41 face outwards ( Figure 5 (F1 indicates the outward movement direction) The movement drives the transmission gear 44 to rotate in the forward direction, and the forward rotation of the transmission gear 44 drives the linear rack 45 on the side of the limiting plate 42 to move inward ( Figure 5 F2 in the text indicates the inward movement of the limit plate 42.

[0074] Reference Appendix Figure 2 A drive disk 20 is rotatably mounted on the operating table 2. Several drive components 5 adapted to the cutting station 3 are slidably mounted on the drive disk 20, and each drive component 5 has a cutting blade 50 at its end. A drive motor is mounted at the lower end of the operating table 2, and the drive motor is connected to the drive disk 20 for transmission, meaning the drive motor is suitable for driving the drive disk 20 to rotate in both directions. A spiral groove 22 is formed on the upper surface of the drive disk 20, and a driven roller 53 adapted to the spiral groove 22 is rotatably mounted on the bottom wall of the drive rod 52. A support ring 21 is mounted on the operating table 2, and the support ring 21 is located outside the drive disk 20, with a horizontal height not less than the horizontal height of the drive disk 20.

[0075] Reference Appendix Figure 2 and Figure 3 The driving component 5 includes: a fixed block 51 disposed on the support ring 21; a driving rod 52 extending radially along the driving disk 20 and sliding through the fixed block 51; and a cutting blade 50 located below the cutting station 3. When the driving disk 20 rotates, it drives the driving rod 52 to slide radially, and the cutting blade 50 passes over the cutting station 3 to cut the copper wire 60. When the driving disk 20 rotates forward, the sidewall of the spiral groove 22 drives the driven roller 53 to move the driving rod 52 radially inward; when the driving disk 20 rotates in the reverse direction, the sidewall of the spiral groove 22 drives the driven roller 53 to move the driving rod 52 radially outward.

[0076] Reference Appendix Figure 3 In order to improve the stability of the radial movement of the cutting blade 50, the support platform 1 is provided with several limiting grooves along the radial direction. Each limiting groove corresponds to one cutting blade 50, and the cutting blade 50 is adapted to slide radially within the limiting groove.

[0077] Reference Appendix Figure 3The support platform 1 is equipped with several vision sensors 31 adapted to the cutting station 3; the limiting plate 42 is located outside the vision sensor 31; when the copper wire 60 is not inserted into the cutting station 3, the two limiting plates 42 retract into the cutting station 3, and the vision sensor 31 is adapted to detect whether the copper wire 60 is inserted; after the copper wire 60 is clamped and limited by the two positioning plates 41, the two limiting plates 42 move towards each other and block the upper part of the vision sensor 31, and the vision sensor 31 is adapted to detect whether the lower end of the copper wire 60 protrudes from the cutting station 3. Figure 3 The dotted line represents copper wire 60. At this time, copper wire 60 is clamped and limited by the two positioning plates 41, and its outer wall abuts against the limiting plate 42. Figure 3 The portion of the copper wire 60 protruding from the bottom of the cutting station 3, which is in the middle dotted line state, has been cut off by the cutting blade 50; F1 indicates the cutting direction of the cutting blade.

[0078] Reference Appendix Figure 3 The bottom wall of the operating table 2 is provided with a collection hopper 23, which is located below the cutting station 3, and is used to collect the cut copper wires 60.

[0079] The working principle is as follows:

[0080] After the stator 6 is fixed on the support platform 1, each copper wire 60 of the stator 6 moves downward and passes through the cutting hole 30;

[0081] Reference Appendix Figure 6 During the downward movement of the copper wire 60, it presses the two positioning plates 41 to move outward synchronously. As the positioning plates 41 move outward, the rotation of the transmission gears 44 drives the corresponding limiting plates 42 to move inward (e.g., Figure 5 In the diagram, F1 indicates that the positioning plate 41 moves outward; F2 indicates that the limiting plate 42 moves inward.

[0082] After the copper wire 60 is clamped and limited from both sides by the two positioning plates 41 and the positioning holes 43, the side wall of the limiting plate 42 abuts against the outer wall of the copper wire 60, and a gap is left between the two limiting plates 42 to avoid obstructing the vision sensor 31; the cutting blade 50 moves radially in the axial direction of the support table 1 ( Figure 6 (F3 indicates the moving direction of the cutting blade 50). At this time, the two sides of the copper wire 60 are clamped and limited by the two positioning plates 41, which can prevent axial displacement of the outer wall of the copper wire 60 during the cutting process of the cutting blade 50; while the limiting plate 42 can prevent radial displacement of the copper wire 60 during cutting, ensuring the flatness of the end of the copper wire 60 when it is cut.

[0083] At least one embodiment provides a method for operating a stator winding cutting device, the method comprising:

[0084] After the stator 6 is fixed on the support platform 1, each copper wire 60 moves downward and is inserted into the corresponding cutting station 3;

[0085] When the copper wire 60 is inserted between the two limiting plates 42, it pushes the two positioning plates 41 to slide outward synchronously. The two positioning plates 41 are adapted to clamp and limit the axial movement of the copper wire 60.

[0086] When the positioning plate 41 slides outward, it drives the limiting plate 42 to slide inward until the side wall of the limiting plate 42 abuts against the outer wall of the copper wire 60, thereby limiting the radial movement of the copper wire 60.

10. The stator winding cutting equipment as described in claim 1, characterized in that, The bottom wall of the operating table (2) is provided with a collection hopper (23), which is located below the cutting station (3) and is used to collect the cut copper wires (60).

11. A method for operating a stator winding cutting device, characterized in that, The stator winding cutting equipment as described in any one of claims 1-10, wherein the working method includes: After the stator (6) is fixed on the support platform (1), each copper wire (60) moves downward and is inserted into the corresponding cutting station (3). When the copper wire (60) is inserted between the two limiting plates (42), it pushes the two positioning plates (41) to slide outward synchronously. The two positioning plates (41) are adapted to clamp and limit the axial movement of the copper wire (60). When the positioning plate (41) slides outward, it drives the limiting plate (42) to slide inward until the side wall of the limiting plate (42) abuts against the outer wall of the copper wire (60) to limit the radial movement of the copper wire (60).
