Abstract
Description
Technical Field
[0001] This application relates to the field of flat wire expansion technology, and in particular to a flat wire stator welding end expansion device. Background Technology
[0002] Flat wire stator refers to a motor stator winding that uses flat copper wire windings instead of the original round copper wire windings. Due to its advantages such as high slot fill factor, high efficiency, and high power density, flat wire stator is widely used in new energy vehicles, high-efficiency industrial motors, and home appliances.
[0003] The main function of flat wire stator expansion equipment is to bend the ends of motor windings, increasing the cross-sectional area of the windings and thus improving their conductivity. Existing flat wire stator expansion equipment has a low degree of automation, and its bending efficiency needs improvement.
[0004] In view of the above-mentioned related technologies, this application provides a device capable of automatically expanding flat wire stators. Utility Model Content
[0005] To achieve automated expansion of flat wires in flat wire stators, this application provides a flat wire stator welding end expansion device.
[0006] The flat wire stator welding end expansion device provided in this application adopts the following technical solution:
[0007] A flat wire stator welding end expansion device includes a placement mechanism for installing the flat wire stator, a pressing mechanism that is lifted and disposed on the top of the positioning mechanism and used to press the flat wire stator, a positioning mechanism disposed on one side of the positioning mechanism and used to press the bottom of the flat wire, and a bending mechanism disposed corresponding to the positioning mechanism and used to bend the flat wire.
[0008] By adopting the above technical solution, when using the above-mentioned wire expansion equipment, the flat wire stator is positioned and installed in the placement mechanism, and then the clamping mechanism is vertically lowered. The clamping mechanism clamps the flat wire stator to ensure the overall stability of the flat wire stator. Then, the positioning mechanism is activated to position the flat wire on the side that needs to be bent to ensure the stability of the flat wire to be bent. Finally, the bending mechanism bends the flat wires on the winding in sequence. The above-mentioned wire expansion equipment has a high degree of automation, reduces the number of manual operation steps, and the bending efficiency and accuracy are both ideal.
[0009] Optionally, the placement mechanism includes a fixed disk, a rotating disk rotatably mounted on the top of the fixed disk, a placement seat disposed on the rotating disk for placing the flat wire stator, and a rotation drive component disposed on the fixed disk for driving the rotating disk to rotate, wherein the placement seat and the rotating disk are coaxially arranged.
[0010] By adopting the above technical solution, the structural composition of the placement mechanism is disclosed. The flat wire stator is positioned and placed on the placement seat. After the expansion of a set of flat wires is completed, the rotation drive is activated to rotate the placement seat horizontally along the axis of the fixed plate, so that the bending mechanism can expand another set of flat wires on the stator. The structure of the placement mechanism is simple and can realize the automatic rotation of the flat wire stator, thereby improving the bending efficiency.
[0011] Optionally, the clamping mechanism includes a clamping plate disposed on the top of the fixed plate, a clamping seat that is lifted and installed on the clamping plate, and a first lifting drive component that drives the clamping seat to lift and lower. The clamping seat and the rotating plate are coaxially arranged.
[0012] By adopting the above technical solution, after the flat wire stator is placed, the first lifting drive component is activated, so that the clamping seat presses against the top of the flat wire stator, ensuring the stability of the stator when the bending mechanism expands the wire.
[0013] Optionally, the positioning mechanism includes a positioning plug for inserting into the bottom of the flat wire, a first horizontal moving member for driving the positioning plug to move horizontally, and a second lifting driving member for driving the first horizontal moving member to rise and fall.
[0014] By adopting the above technical solution, the structural composition of the positioning mechanism is disclosed. The positioning plug is inserted into the flat wire to be bent through the first horizontal moving part, which has a pressing effect on the bottom of the flat wire, further improving the stability during wire expansion. The second lifting drive part can realize the vertical lifting of the positioning plug, so that the positioning mechanism can position flat wires of different sizes and improve the adaptability of the positioning mechanism.
[0015] Optionally, the positioning plug has a positioning slot on one end facing the stator, and the end of the positioning slot has a first guide slope.
[0016] By adopting the above technical solution, the positioning slot and the flat wire are connected and matched. The setting of the first guide slope improves the connection efficiency of the positioning plug and the flat wire and reduces the interference between the flat wire and the positioning plug.
[0017] Optionally, the bending mechanism includes a bending plug, a third lifting drive for driving the bending plug to rise and fall, a second horizontal moving member for driving the third lifting drive to move horizontally, and a fourth lifting drive for driving the second horizontal moving member to rise and fall. The bending plug has a bending slot that extends through the upper and lower end faces and is used for insertion into a flat wire.
[0018] By adopting the above technical solution, the structural composition of the bending mechanism is disclosed. After the positioning mechanism positions the flat wire to be bent, the bending plug moves from top to bottom so that the bending slot is engaged with the flat wire. Then, the second horizontal moving part drives the bending plug to move horizontally, and the bending plug drives the flat wire to move horizontally to achieve bending and wire expansion.
[0019] Optionally, the bending plug is further provided with a partition in the bending slot, the partition dividing the bending slot into a first slot for placing a completed bend and a second slot for placing a bend.
[0020] By adopting the above technical solution, the partition divides the bending slot into a first slot and a second slot. After the expansion of a flat wire is completed, the bending plug is moved upward again and then moved toward the stator so that the second slot corresponds to the flat wire to be bent. The bending operation is repeated. In the bending operation after the second time, the flat wires that have been bent are all located in the second slot, so that multiple sets of flat wires are aligned horizontally.
[0021] Optionally, the clamping seat has a relief groove for the bending plug to move up and down.
[0022] By adopting the above technical solution and setting the clearance groove, the probability of interference between the bent plug and the clamping seat can be reduced, and the probability of collision damage to the bent plug can be reduced.
[0023] Optionally, the bending mechanism further includes a guide plug, which is mounted on the second horizontal moving member and located between the bending plug and the positioning plug.
[0024] By adopting the above technical solution, the guide plug can further position the middle of the flat wire and improve the stability during bending.
[0025] Optionally, the guide plug includes two symmetrically arranged guide rods, and the second horizontal moving member is provided with a clamping drive member that drives the guide rods toward or away from each other.
[0026] By adopting the above technical solution, the guide plug includes two guide rods, and the movement of the guide rods is realized by the clamping drive component, so as to clamp and press the flat wire.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. This application realizes the wire expansion and bending process of flat wire stators by setting up a placement mechanism, a clamping mechanism, a positioning mechanism, and a bending mechanism. The process has a high degree of automation and the bending efficiency and accuracy are both ideal.
[0029] 2. By setting the first guide slope, this application improves the insertion efficiency of the positioning plug and the flat wire, and reduces the interference between the flat wire and the positioning plug;
[0030] 3. This application divides the bending slot into a first slot and a second slot by setting a partition, so that flat lines bent in the same direction can be aligned horizontally. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0040] This application discloses a flat wire stator welding end expansion device.
[0041] Reference Figure 1 A flat wire stator welding end expansion device includes a placement mechanism 1 for installing the flat wire stator, a pressing mechanism 2 that is lifted and installed on top of a positioning mechanism 3, a positioning mechanism 3 located on one side of the placement mechanism 1, and a bending mechanism 4 located above the positioning mechanism 3. All of these components are mounted on the top surface of a workbench (not shown in the figure).
[0042] Reference Figure 1 and Figure 2 The placement mechanism 1 includes a fixed disk 11, a rotating disk 12 rotatably mounted on the top of the fixed disk 11, a placement seat 13 disposed on the rotating disk 12 for placing the flat wire stator, and a rotation drive 14 mounted on the fixed disk 11.
[0043] The fixed plate 11 is bolted to the top of the worktable. The rotating plate 12 is rotatably mounted on the top of the fixed plate 11. The rotation drive 14 is fixed to the bottom of the fixed plate 11. The rotation drive 14 is a prior art rotary motor, and its output shaft and the rotation shaft of the rotating plate 12 are driven by gears. The placement seat 13 is coaxially fixed to the rotating plate 12, and the top of the placement seat 13 has a placement groove 131 for placing the flat wire stator.
[0044] The clamping mechanism 2 includes a clamping plate 21 disposed above the fixed plate 11, a clamping seat 22 that is lifted and installed below the clamping plate 21, and a first lifting drive component 23 that drives the clamping seat 22 to rise and fall. The clamping plate 21 is a rectangular plate, and each of its four corners is provided with a connecting rod 24 that is fixedly connected to the top of the worktable.
[0045] The first lifting drive component 23 is a conventional direct-drive electric cylinder, fixed to the fixed plate 11 with its output shaft facing downwards. The clamping seat 22 is cylindrical in shape and is coaxially fixed to the output shaft of the first lifting drive component 23. Two sets of guide rods 25 are vertically slidably mounted on the clamping plate 21, and the two sets of guide rods 25 are symmetrically arranged along the axis of the clamping seat 22. A connecting plate 26 is provided at the end of the guide rod 25 away from the clamping seat 22 to improve the stability of the guide rod 25 during sliding.
[0046] Reference Figure 3 and Figure 4The positioning mechanism 3 includes a positioning plug 31, a first horizontal moving member 32 that drives the positioning plug 31 to move horizontally, and a second lifting drive member 33 that drives the first horizontal moving member 32 to move up and down. The first horizontal moving member 32 is a prior art reciprocating electric cylinder, and the second lifting drive member 33 is a prior art linear motor module. The second lifting drive member 33 is arranged vertically, and the first horizontal moving member 32 is arranged horizontally. A first lifting plate 331 for fixing the first horizontal moving member 32 is mounted on the slider of the second lifting drive member 33.
[0047] The positioning plug 31 is fixed to the output shaft end of the first horizontal moving member 32. The end of the positioning plug 31 facing the stator has a positioning slot 311 that extends through both the upper and lower end faces. The positioning slot 311 is used to connect with the bottom of the flat wire to ensure the stability of the bottom of the flat wire. The positioning plug 31 also has a first guide slope 312 on the open end face of the positioning slot 311 to improve the connection efficiency between the positioning plug 31 and the flat wire.
[0048] Reference Figure 5 , Figure 6 and Figure 7 The bending mechanism 4 includes a bending plug 41, a third lifting drive 42, a second horizontal moving part 43, a fourth lifting drive 44, a guide plug 45, and a clamping drive 46.
[0049] The third lifting drive component 42 is a prior art cylinder linear module, the second horizontal moving component 43 is a prior art motor linear module, the fourth lifting drive component 44 is a prior art motor linear module, and the clamping drive component 46 is a prior art clamping cylinder.
[0050] The slider of the fourth lifting drive component 44 is fixed with a second lifting plate 441 for mounting the second horizontal moving component 43, and the slider of the second horizontal moving component 43 is fixed with a horizontal extension plate 431 for mounting the third lifting drive component 42. The vertical lifting of the bending plug 41 is achieved by the third lifting drive component 42. Compared with the motor linear module, the cylinder linear module has the advantage of rapid start and stop, improving the efficiency of wire expansion bending.
[0051] The bending plug 41 is fixed to the slider of the third lifting drive component 42. The bending plug 41 has a bending slot 411 that extends through the upper and lower end faces. The bending slot 411 is a rectangular groove that extends along the horizontal movement direction of the bending plug 41. The two ends of the bending slot 411 along the sliding direction of the second horizontal moving component 43 are closed. A partition 412 is also integrally provided inside the bending slot 411 of the bending plug 41. The partition 412 is arranged vertically and divides the bending slot 411 horizontally into a first slot 4111 and a second slot 4112. The first slot 4111 is used to place the flat wire that has been bent, and the second slot 4112 is used to place the flat wire to be bent. The bending plug 41 bends only one flat wire each time it moves horizontally. The clamping seat 22 also has a relief groove 221 on the top side facing the bending mechanism 4, which corresponds to the bending plug 41, so that the end of the bending plug 41 can be moved horizontally to the flat wire close to the stator axis.
[0052] The guide plug 45 includes two symmetrical guide rods 451, with a guide slot 452 between the two guide rods 451. The guide slot 452 extends horizontally longer than the positioning slot 311. The guide plug 45 has a second guide ramp 453 at the end of the guide slot 452 to improve the accuracy of the insertion of the guide plug 45 and the flat wire.
[0053] The ends of the two guide rods 451 are respectively fixed to the two output shafts of the clamping drive 46. The clamping drive 46 is fixed to the bottom of the third lifting drive 42, that is, the guide plug 45 is located between the bending plug 41 and the positioning plug 31. The guide plug 45 can clamp and position the middle of the flat wire, further ensuring the stability during bending.
[0054] The implementation principle of the flat wire stator welding end expansion device in this application embodiment is as follows: the flat wire stator is positioned and placed on the placement seat 13. The flat wire to be expanded and the positioning mechanism 3 are aligned by rotating the drive component 14. Then, the clamping mechanism 2 is activated to press the clamping seat 22 on the top of the stator to achieve overall clamping and fixing of the stator.
[0055] The height of the positioning plug 31 is adjusted by the second lifting drive 33 so that the positioning slot 311 corresponds to the bottom of the flat wire. Then, the first horizontal moving part 32 is activated so that the positioning slot 311 is inserted into the bottom of the flat wire to stabilize the bottom of the flat wire. The height of the bending plug 41 is adjusted by the fourth lifting drive 44 so that the bending plug 41 corresponds to the top of the flat wire. At this time, the guide plug 45 is inserted into the middle of the flat wire. The clamping drive 46 further clamps and fixes the flat wire. Then, the third lifting drive 42 is activated so that the flat wire is inserted into the second slot 4112. After that, the second horizontal moving part 43 is activated so that the bending plug 41 drives the flat wire to move horizontally to realize the bending operation.
[0056] After completing the bending of a flat wire, repeat the bending operation. After the first bending of each group of flat wires, the bending plug 41 is inserted each time. The flat wires that have been bent are neatly arranged in the first slot 4111, and the flat wires to be bent are located in the second slot 4112.
[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
