Description

Technical Field

[0001] The present invention relates to the technical field of motor welding, and in particular to a permanent magnet synchronous motor welding device. Background Art

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a constant magnetic field. Its rotor speed is synchronized with the stator winding current frequency. It has the advantages of simple structure, high efficiency, and high power density. It is widely used in industrial automation, electric vehicles and other fields.

[0003] Permanent magnet synchronous motor welding equipment primarily includes equipment used to weld stator and rotor components, typically using resistance welding. Resistance welding, a technique that uses high current to instantly melt metal to create a strong connection, is suitable for welding stator windings and motor casings in new energy vehicle motors.

[0004] The existing motor welding equipment has poor versatility in the support bracket during welding and cannot adapt to the clamping and fixation of synchronous motors of different specifications, resulting in frequent adjustment of equipment parameters when changing models, seriously affecting production efficiency. At the same time, during the pressure-melting welding process between the commutator segments and the winding copper wire, the copper wire is subjected to excessive pulling force, which can easily cause diameter deformation or cracking, directly affecting the service life of the motor. In addition, there is a lack of effective support under the winding copper wire in the welding area, resulting in insufficient contact area between the copper wire and the welding surface, which is prone to breakage due to stress concentration in later operation, affecting welding quality and product reliability. Therefore, the present application provides a permanent magnet synchronous motor welding equipment to meet the needs. Summary of the Invention

In addition, by adopting a toothed turntable and a rigid connection structure with the long axis, the displacement during welding vibration is reduced, the amplitude is reduced, and the occurrence of welding deformation is effectively suppressed.

The contact trigger mechanism between the contact block and the support frame ensures that the copper wire is stably positioned before pressure is applied, avoiding sudden stress concentration. In addition, the pre-pressing process makes the contact surface between the copper wire and the commutator segment fit more closely, reducing the phenomenon of cold welding or insufficient fusion, and improving the consistency of welding quality. Moreover, the pre-shaping of the copper wire reduces abnormal vibration during welding, reduces electrode wear, and extends the service life of equipment and products.

[0020] By setting up a support spray component, the arc-shaped triangular block can be dynamically filled and accurately inserted into the gap between the copper wire and the commutator, so that the copper wire fitting area is increased, effectively avoiding cold soldering. At the same time, the touch switch is linked accordingly, spraying conductive liquid to enhance conductivity and reduce contact resistance, reduce stress concentration caused by Joule heat during operation, extend product life and stress distribution, optimize the support of the pre-wired wire and the arc-shaped triangular block to make the copper wire force uniform, improve fatigue resistance, and the metal penetration layer formed by the conductive liquid can inhibit the expansion of microcracks and extend the life of the motor in a vibration environment.

[0043] As an implementation method in this embodiment, Figures 3 to 6As shown, the clamping bracket assembly 6 includes a welding support frame 61, which is installed on the top of the operating table 5, and a switch slot is provided at the end of the welding support frame 61. A small frame 62 is installed on the top of the welding support frame 61, and a first gear 64 is rotatably connected to the interior of the small frame 62. A rocker 63 is installed on the surface of one end of the first gear 64, and the end of the first gear 64 is meshedly connected to a transmission gear 65, and one end of the transmission gear 65 is meshedly connected to a second gear 66. One end of the second gear 66 is meshedly connected to a toothed turntable 67, and the surface of the toothed turntable 67 is rotatably connected to a plurality of rotating wheels 68. One end of the toothed turntable 67 is rotatably connected to a fixed disk 610, and the inner wall of the fixed disk 610 is in contact with the surfaces of the plurality of rotating wheels 68. The other end of the toothed turntable 67 is rotatably connected to a rotating sleeve 69, and the rotating sleeve 69 is installed on the inner wall of the welding support frame 61. The surface of the fixed disk 610 is rotatably connected to multiple connecting plates 613, and one end of the multiple connecting plates 613 is rotatably connected to a rotating plate 612. One side of the rotating plate 612 is rotatably connected to a long shaft 611, and one end of the long shaft 611 is inserted into the interior of the toothed turntable 67. One end of the rotating plate 612 is rotatably connected to a clamping wheel 614. When the motor winding stator 12 moves to the welding support frame 61, the clamping bracket assembly 6 starts to run. At this time, the motor shaft at the center of the winding stator 12 is inserted into the center of the fixed disk 610, and then by shaking the rocker 63 at one end of the small frame 62, the first gear 64 starts to follow the rocker 63 rotates together, and then the rotating first gear 64 drives the meshing transmission gear 65 to rotate. As the transmission gear 65 rotates, the second gear 66 meshing with one end of the transmission gear 65 also starts to rotate. Then the second gear 66 drives the toothed turntable 67 meshing with one end to start to rotate slowly on one end of the fixed disk 610. At this time, the rotating wheel 68 connected to the surface of the toothed turntable 67 starts to rotate close to the inner wall of the fixed disk 610 to ensure the stability of the toothed turntable 67. When the toothed turntable 67 rotates, the multiple groups of long shafts 611 inserted on the surface of the toothed turntable 67 start to move together with the rotation direction of the toothed turntable 67. As the multiple groups of long shafts 611 move, the gears installed in the long The multiple rotating plates 612 rotatably connected to one end of the shaft 611 also start to rotate. When the multiple rotating plates 612 rotate, the multiple connecting plates 613 rotatably connected to one end of the multiple rotating plates 612 are driven to move together. At this time, the multiple connecting plates 613 rotate on the fixed disk 610, and when the multiple connecting plates 613 rotate on the fixed disk 610, the multiple rotating plates 612 are respectively flipped by the corresponding connected connecting plates 613, so that the multiple rotating plates 612 at this time rotate around the axis of the corresponding long shaft 611. When the multiple rotating plates 612 rotate, the clamping wheels 614 rotatably connected to the ends of the multiple rotating plates 612 are synchronously flipped toward the axis, continuously reducing the size of the axis around which the multiple clamping wheels 614 are connected.Then the motor shaft is clamped. When the motor shaft needs to rotate, the entire clamping bracket assembly 6 can rotate on the rotating sleeve 69 to achieve stable clamping of the axis, avoiding deflection caused by unilateral stress and avoiding deviation of the motor axis from the welding position.

[0044] As an implementation method in this embodiment, Figures 6 to 9 As shown, the top contact pressure line assembly 7 includes a hanger 71, which is installed at the bottom of the pressure melting welding head 4, one end of the hanger 71 is connected with a rotating shaft 72, one end of the rotating shaft 72 is installed with a first rotating plate 73, the bottom of the first rotating plate 73 is installed with a top contact rod 74, and the other end of the rotating shaft 72 is installed with a second rotating plate 75. The first rotating plate 73 and the second rotating plate 75 are both fixed to the end of the rotating shaft 72, and one end of the second rotating plate 75 is rotatably connected to a rotating wheel cylinder 76. An extension rod 77 is installed at one end of the pressure melting welding head 4, and a lower pressure rod 78 is installed at the bottom of the extension rod 77. A contact block 79 is provided at the bottom of the lower pressure rod 78, and the contact block 79 is on the same axis as the switch slot at the end of the welding support frame 61. When the top contact rod 74 is pushed upward, when the top contact rod 74 moves upward, the first rotating plate 73 and the second rotating plate 75 are fixed to the end of the rotating shaft When the second rotating plate 75 rotates, the rotary drum 76 connected to the end of the second rotating plate 75 starts to push the copper wire of the winding lead wire 13 downward. When the copper wire is pushed by the rotary drum 76, it begins to bend in an arc. At the same time, as the pressure-melting welding head 4 descends, the extension rod 77 installed at the end of the pressure-melting welding head 4 drives the lowering rod 78 to move downward. As the lowering rod 78 moves, the contact block 79 installed at the bottom of the lowering rod 78 slowly comes into contact with the switch in the switch slot on the welding support frame 61.

[0045] As an implementation method in this embodiment, Figures 8 to 12As shown, the support spray assembly 8 includes a hollow frame 81, which is installed at the bottom of one end of the pressure-melting welding head 4. A toothed piston rod 82 is inserted at the bottom of the hollow frame 81, and a stop block 83 is installed at the bottom of the toothed piston rod 82. The stop block 83 is installed above the winding lead-out line 13. Two groups of support plates 84 are installed on the top of the toothed piston rod 82. Slide blocks 85 are installed at both ends of the two groups of support plates 84. A slide groove 86 is installed on the inner wall of the hollow frame 81. The slide block 85 slides in the slide groove 86. A soft spring 87 is installed in the middle of the two groups of support plates 84. The support plate 84 at the top of the soft spring 87 is fixedly connected to the top inner wall of the hollow frame 81. Two groups of rotating rods are inserted at the bottom of both ends of the hollow frame 81 814, the surfaces of the two sets of rotating rods 814 are installed with rotating gears 88, the ends of the rotating gears 88 are installed with connecting frames 89, the bottom of the connecting frames 89 is installed with liquid guiding rods 810, the surface of the liquid guiding rods 810 is installed with liquid storage tanks 811, the ends of the liquid guiding rods 810 are installed with liquid feeding rods 815, the bottom of the liquid feeding rods 815 is installed with a one-way valve 812, the output end of the one-way valve 812 is rotatably connected with an arc-shaped triangular block 813, when the winding lead-out wire 13 is pushed by the rotating drum 76 to complete the winding, the support spray assembly 8 starts to operate, at this time, the toothed piston rod 82 plugged into the bottom of the hollow frame 81 moves downward together during the descent process, and the toothed piston rod 82 installed at the bottom of the toothed piston rod 82 moves downward together. After coming into contact with the commutator segment 14, the stop block 83 starts to move upward, and at this time, the stop block 83 drives the toothed piston rod 82 installed on the top to move upward together. When the toothed piston rod 82 moves upward, the support plate 84 installed on the top of the toothed piston rod 82 drives the sliders 85 installed at both ends to move upward in the slide groove 86 installed on the inner wall of the hollow frame 81. At this time, the soft spring 87 on the support plate 84 is pushed by the support plate 84 and contracts. At the same time, the movement of the toothed piston rod 82 causes the rotating gears 88 meshing at both ends to drive the rotating rod 814 to rotate. When the two sets of rotating gears 88 rotate, the connecting frame 89 installed at the end of the rotating gear 88 rotates. As the gear 88 rotates, the connecting frame 89 drives the liquid guiding rod 810 to move closer to the toothed piston rod 82, and then the liquid feeding rod 815 installed at the end of the liquid guiding rod 810 begins to insert into the gap between the winding lead wire 13 and the commutator segment 14, and then the arc-shaped triangular block 813 at the front end of the liquid feeding rod 815 supports the copper wire of the winding lead wire 13. At this time, the contact block 79 installed at the bottom of the pressing rod 78 slowly comes into contact with the switch in the switch slot on the welding support frame 61, and then the conductive liquid passes from the liquid storage tank 811 through the liquid guiding rod 810 to the liquid feeding rod 815, and then is sprayed out through the one-way valve 812, and then sprayed to the bottom of the copper wire through the opening of the arc-shaped triangular block 813.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When using this device, first clean the surface of the operating table 5 inside the body 1, then place the winding stator 12 in the clamp bracket 11, and then start the drive motor 10 through the control center 2 to drive the slide table 9 to move toward the clamping bracket assembly 6.

[0048] When the motor winding stator 12 moves to the welding support frame 61, the clamping bracket assembly 6 starts to operate. At this time, the motor shaft at the center of the winding stator 12 is inserted into the center of the fixed disk 610. Then, by shaking the rocker 63 at one end of the small frame 62, the first gear 64 starts to rotate together with the rocker 63. Then, the rotating first gear 64 drives the meshing transmission gear 65 to rotate. As the transmission gear 65 rotates, the second gear 66 meshing with one end of the transmission gear 65 also starts to rotate. The second gear 66 drives the toothed turntable 67 with one end meshing and connected to start to rotate slowly on one end of the fixed disk 610. At this time, the rotating wheel 68 connected to the surface of the toothed turntable 67 starts to rotate closely against the inner wall of the fixed disk 610 to ensure the stability of the toothed turntable 67. When the toothed turntable 67 rotates, the multiple groups of long shafts 611 inserted on the surface of the toothed turntable 67 start to move along with the direction of rotation of the toothed turntable 67. As the multiple groups of long shafts 611 rotate, the toothed turntable 67 rotates. When the plurality of rotating plates 612 are moved, the plurality of rotating plates 612 rotatably connected at one end of the long shaft 611 also start to rotate. When the plurality of rotating plates 612 rotate, the plurality of connecting plates 613 rotatably connected at one end of the plurality of rotating plates 612 are driven to move together. At this time, the plurality of connecting plates 613 rotate on the fixed disk 610, and when the plurality of connecting plates 613 rotate on the fixed disk 610, the plurality of rotating plates 612 are respectively flipped by the corresponding connected connecting plates 613, so that the plurality of rotating plates 612 at this time rotate around the axis of the corresponding connected long shaft 611, and when the plurality of rotating plates 612 rotate, the clamping wheels 614 rotatably connected at the ends of the plurality of rotating plates 612 are synchronously flipped toward the axis, continuously reducing the size of the axis around which the plurality of clamping wheels 614 surround, and then the motor shaft is clamped. When the motor shaft needs to rotate, the entire clamping bracket assembly 6 can rotate on the rotating sleeve 69 to achieve stable clamping of the axis, avoid deflection caused by unilateral stress, and avoid deviation of the motor axis from the welding position.

[0049] After the clamping bracket assembly 6 completes the clamping of the motor shaft, the driving frame 3 starts to run. At this time, the driving frame 3 drives the pressure-melting welding head 4 to move downward. When the pressure-melting welding head 4 moves downward, the top contact wire pressing assembly 7 and the support spray assembly 8 move downward synchronously. At this time, during the descending process of the pressure-melting welding head 4, the top contact wire pressing assembly 7 first contacts the top of the welding support frame 61, and then the top contact rod 74 is pushed upward. When the top contact rod 74 moves upward, the first rotating plate 73 moves upward synchronously with the top contact rod 74. At this time, the first rotating plate 73 starts to drive the rotating shaft 72 installed on the hanger 71 to rotate, and when the rotating shaft 72 During rotation, the second rotating plate 75 installed at the other end of the rotating shaft 72 begins to rotate together with the first rotating plate 73. When the second rotating plate 75 rotates, the rotating drum 76 connected to the end of the second rotating plate 75 begins to push the copper wire of the winding lead wire 13 downward. When the copper wire is pushed by the rotating drum 76, it begins to bend in an arc. At the same time, as the pressure-melting welding head 4 descends, the extension rod 77 installed at the end of the pressure-melting welding head 4 drives the downward pressure rod 78. As the downward pressure rod 78 moves, the contact block 79 installed at the bottom of the downward pressure rod 78 slowly contacts the switch in the switch slot on the welding support frame 61, and then supports the spray assembly 8 to start running.

[0050] When the winding lead wire 13 is pushed by the rotating drum 76 to complete the winding, the support spray assembly 8 starts to operate. At this time, the toothed piston rod 82 connected to the bottom of the hollow frame 81 moves downward together during the descent process. As the block 83 installed at the bottom of the toothed piston rod 82 comes into contact with the commutator segment 14, the block 83 starts to move upward. At this time, the block 83 drives the toothed piston rod 82 installed on the top to move upward together. When the toothed piston rod 82 moves upward, the support plate 84 installed on the top of the toothed piston rod 82 drives the sliders 85 installed at both ends to move upward in the slide groove 86 installed on the inner wall of the hollow frame 81. At this time, the soft spring 87 on the support plate 84 is pushed by the support plate 84 and shrinks. At the same time, the movement of the toothed piston rod 82 causes the rotating gears 88 engaged at both ends to drive the rotating rod 814 to rotate. When rotation occurs, the connecting frame 89 installed at the end of the rotating gear 88 rotates together with the rotating gear 88. At this time, the connecting frame 89 drives the liquid guiding rod 810 to move closer to the toothed piston rod 82, and then the liquid feeding rod 815 installed at the end of the liquid guiding rod 810 begins to insert into the gap between the winding lead wire 13 and the commutator segment 14, and then the arc-shaped triangular block 813 at the front end of the liquid feeding rod 815 supports the copper wire of the winding lead wire 13. At this time, the contact block 79 installed at the bottom of the lower pressure rod 78 slowly contacts the switch in the switch slot on the welding support frame 61, and then the conductive liquid is discharged from the liquid storage tank 811 through the liquid guiding rod 810 to the liquid feeding rod 815, and then sprayed through the one-way valve 812, and then sprayed to the bottom of the copper wire through the opening of the arc-shaped triangular block 813, and then the pressure-melting welding head 4 continues to descend to pressure-melt the copper wire at the end of the commutator segment 14 and the winding lead wire 13.
