Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, in particular to a flaring device and motor assembly equipment. Background Art

[0002] The stator is an important part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame. Among them, the stator winding of the flat wire motor is mainly composed of flat wire. Compared with the round wire motor, the flat wire motor has the advantages of low cost, excellent temperature performance and good rigidity, so it is widely used in various mechanical equipment.

[0003] When producing multi-layer flat wire stators, the ends of the stacked flat wires need to be divided into two groups and welded in sequence. Before welding, the ends of the flat wires need to be twisted into a certain shape. After the flat wires are stacked, the ends of each layer of flat wires are tightly together. In order to facilitate the twisting operation, a certain distance must be left between the ends of the two groups of flat wires.

[0004] The traditional flaring device clamps the end of the flat wire with a clamping jaw, and then transmits the power of the driver to the clamping jaw through a transmission mechanism, so that the clamping jaw moves outward along a predetermined path, thereby achieving the purpose of flaring the end of the flat wire. However, when the power is transmitted through the transmission mechanism, the transmission mechanism is generally fixed with bolts. After multiple stretching, the bolts of the transmission mechanism and the threaded holes where the bolts are set will wear and deform, and the driving jaw will have errors in moving, which often causes the clamping jaw to not move into place and not clamp the end of the flat wire.

[0031] See also Figures 1 to 3 The embodiment of the present application provides a flaring device 100, which is used to process a flat wire winding. The flat wire winding is used in the motor of a new energy vehicle, wherein the flat wire winding includes multiple layers of flat wires sequentially arranged from the outside to the inside, each flat wire layer includes multiple flat wires connected by plug-in wires, the cross-sectional shape of the flat wire is a polygon, and the flat wire generally has two flat wire ends. The flaring device 100 is used to flare the flat wire ends to facilitate the subsequent torsional deformation and welding of the flat wire ends.

[0032] See also Figures 2 to 4 The expanding device 100 includes a clamping structure 200 and a driving structure 300 .

[0033] See also Figures 2 to 4 The clamping structure 200 includes a horizontally arranged bearing turntable 201, a clamping driver 202, and a clamping claw 203 arranged on the clamping driver 202 and controlled by the clamping driver 202. The clamping driver 202 can control the clamping claw 203 to clamp the end of the flat wire, or control the clamping claw 203 to release the clamped flat wire end. The bearing turntable 201 is circular and can be rotatably arranged. The flat wire winding is located at the rotation center of the bearing turntable 201. The clamping driver 202 can reciprocate along a certain radial direction of the bearing turntable 201.

[0034] See also Figures 2 to 4 The driving structure 300 includes a support frame 302 with a sliding groove 3021 and a driving component for driving the support frame 302; wherein the clamping driver 202 is arranged on the support frame 302, and the support frame 302 is slidably connected to the edge of the carrying turntable 201 through the sliding groove 3021, that is, the edge of the disk of the carrying turntable 201 is located in the sliding groove 3021; ​​the driving component drives the support frame 302 to move toward the center position of the carrying turntable 201, so that the clamping driver 202 drives the clamping claw 203 to clamp the flat The wire end, then, the driving assembly drives the support frame 302 to move away from the center position of the carrying turntable 201, so that the clamping driver 202 drives the clamping claw 203 to pull the flat wire end outward to achieve the purpose of expanding the flat wire end. It can be understood that the expanding here refers to pulling the flat wire end outward for a certain distance along a certain radius direction of the carrying turntable 201, and after pulling it into place, the clamping driver 202 drives the clamping claw 203 to release the flat wire end for the next expanding operation.

[0035] See also Figures 2 to 4 In the embodiment of the present application, the support frame 302 is driven to slide by the driving assembly. The support frame 302 moves along a certain radial direction of the carrying turntable 201 under the guidance of the sliding groove 3021 and the edge of the disk of the carrying turntable 201, so that the clamping driver 202 and the clamping claw 203 can move toward the center position of the carrying turntable 201. After moving into position, the clamping driver 202 drives the clamping claw 203 to clamp the end of the flat wire. The driving assembly drives the support frame 302 to move in the reverse direction. When the support frame 302 moves away from the center position of the carrying turntable 201, the clamping claw synchronously pulls the end of the flat wire outward to achieve the expansion of the end of the flat wire. The clamping claw 203 is directly set on the clamping driver 202, which can improve the clamping accuracy of the clamping claw 203 and avoid transmission wear. Moreover, the cooperation between the sliding groove 3021 and the edge of the carrying turntable 201 can improve the moving accuracy of the support frame 302, so that the clamping claw 203 can accurately clamp the end of the flat wire, thereby improving the reliability of the expansion device 100.

[0036] See also Figures 2 to 4 In some embodiments, the clamping driver 202 is a clamping cylinder, and the clamping jaw 203 includes two opposing clamping arms 2031. The clamping driver 202 drives the two clamping arms 2031 to move toward each other to clamp and pull the end of the flat wire, or drives the two clamping arms 2031 to move away from each other to release the end of the flat wire.

[0037] Optionally, the clamping cylinder is an actuator in the pneumatic system, and the clamping cylinder can achieve high-precision clamping and releasing operations. Since the movement of the cylinder is driven by compressed air, adjusting the air pressure and flow can accurately control the movement speed and position of the cylinder, thereby ensuring that the clamping jaws 203 can stably clamp the workpiece. Secondly, the pneumatic system has a fast response speed, and the clamping cylinder can quickly perform clamping and releasing actions, thereby improving the efficiency of clamping and releasing the ends of the flat wires.

[0038] See also Figures 2 to 4 In some embodiments, the clamping arm 2031 includes a fixed section 2033 connected to the clamping cylinder and a clamping section 2034 connected to the fixed section 2033. The clamping driver 202 drives the two fixed sections 2033 to move toward each other so that the two clamping sections 2034 clamp the ends of the flat wire.

[0039] See also Figures 2 to 4 Optionally, the fixed section 2033 can be detachably connected to the clamping cylinder by bolts, and the length direction of the fixed section 2033 and the length direction of the clamping section 2034 are staggered so that the two clamping sections 2034 can clamp the flat wire ends on both sides of the flat wire ends respectively, which is convenient for subsequent pulling and expanding.

[0040] In some embodiments, the clamping section 2034 is provided with a clamping groove 2032, and the two clamping sections 2034 are close to each other so that the two sides of the flat wire end are respectively clamped in the two clamping grooves 2032. It can be understood that through the clamping groove 2032, the reliability of the clamping jaw 203 and the flat wire end can be improved during the pulling process, thereby preventing the flat wire end from detaching from the two clamping sections 2034.

[0041] In some embodiments, a plurality of first positioning blocks 204 are arranged at intervals on the groove wall of one clamping groove 2032, and a plurality of second positioning blocks 205 are arranged at intervals on the groove wall of the other clamping groove 2032. When the two clamping sections 2034 approach each other to clamp the end of the flat wire, the first positioning blocks 204 and the second positioning blocks 205 are arranged alternately in sequence.

[0042] See also Figures 2 to 4It can be understood that, through the cooperation of the first positioning block 204 and the second positioning block 205, the two clamping grooves 2032 can be accurately docked, so that the two clamping sections 2034 have the characteristic of mutual engagement, so that the ends of the flat wire are accurately clamped in the two clamping grooves 2032, thereby improving reliability.

[0043] In some embodiments, the driving structure 300 further includes a guide assembly 303 for guiding the support frame 302 to slide back and forth. The guide assembly 303 is located in the sliding groove 3021 and is provided with two guide assemblies. The supporting turntable 201 is located between the two guide assemblies 303 .

[0044] See also Figures 2 to 4 Optionally, through two guide components 303, the support frame 302 can be guided to reciprocate along a certain radial direction of the carrying turntable 201, thereby improving the accuracy of the movement, and the two guide components 303 can guide the support frame 302 to move on both sides of the carrying turntable 201, thereby improving the reliability of the movement, so that after multiple reciprocating sliding, the clamping jaws 203 can still accurately clamp the end of the flat wire.

[0045] In some embodiments, the guide assembly 303 includes a slider 3032 connected to the supporting turntable 201 and a guide rail 3031 connected to the inner wall of the sliding groove 3021 , and the guide rail 3031 and the slider 3032 are slidably connected.

[0046] See also Figures 2 to 4 Optionally, the slider 3032 can achieve precise sliding control through the guide rail 3031 to ensure that the clamping structure 200 maintains a stable and accurate position adjustment during operation. The guide assembly 303 can effectively reduce the friction and resistance of the clamping structure 200 during movement, and improve the operating efficiency and stability of the overall system. The slider 3032 is made of wear-resistant material, and its surface is specially treated to reduce the friction coefficient and improve the wear resistance. The guide rail 3031 is made of high-strength steel or alloy material, which can withstand large loads and frequent movements.

[0047] See also Figures 2 to 4 By providing the guide assembly 303, the clamping structure 200 can slide smoothly under the drive of the driving assembly, avoiding operation errors caused by position offset or shaking. This not only improves the accuracy of the clamping operation, but also reduces damage to the surface of the flat wire end.

[0048] See also Figures 3 to 5In some embodiments, the driving assembly includes a rotating faceplate 301 rotatably arranged relative to the supporting turntable 201 and a rotating driver for driving the rotating faceplate 301 to rotate around its rotation center. The rotating faceplate 301 is provided with a driving slot 305, and the extension path of the driving slot 305 is a section of an arc. The driving assembly also includes a transmission column 304 slidably arranged in the driving slot 305 and connected to the support frame 302.

[0049] Optionally, the rotation driver may be a servo motor, which may drive the rotating faceplate 301 to rotate via a belt mechanism, a gear mechanism or a chain mechanism.

[0050] See also Figures 3 to 5 Optionally, the rotating faceplate 301 and the supporting turntable 201 are both coaxially rotatably arranged, one end of the driving groove 305 is close to the rotation center, and the other end of the driving groove 305 is away from the rotation center and close to the edge of the rotating faceplate 301. Through the reciprocating rotation of the rotating faceplate 301, the transmission column 304 can slide back and forth in the driving groove 305. Since the extension path of the driving groove 305 is arranged in an arc, it can drive the support frame 302 to perform reciprocating linear movement along a certain radial direction of the supporting turntable 201.

[0051] In some embodiments, multiple support frames 302 are arranged, each support frame 302 is arranged around the rotation center circumference of the rotating flower disk 301, and each support frame 302 is provided with a clamping driver 202 and a transmission column 304, each clamping driver 202 is provided with a clamping claw 203, and the rotating flower disk 301 is provided with a driving groove 305 at the position corresponding to each transmission column 304, the bending direction of each driving groove 305 is the same, and each transmission column 304 is slidably arranged in each driving groove 305.

[0052] See also Figures 3 to 5 Optionally, the driving assembly drives each support frame 302 to move, and at the same time each clamping driver 202 drives each clamping claw 203 to clamp the end of the flat wire. It can be understood that by rotating the rotating disk 301 in the forward direction, multiple clamping claws 203 respectively clamp multiple flat wire ends, and then by rotating the rotating disk 301 in the reverse direction, the simultaneous expansion of multiple flat wire ends is achieved.

[0053] See also Figures 3 to 5 The utility model also proposes a motor assembly device, which includes a flaring device 100. The specific structure of the flaring device 100 refers to the above embodiment. Since the motor assembly device adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0054] In some embodiments, the motor assembly equipment also includes a driving motor, which is used to drive the expanding device 100 to rotate as a whole to a predetermined angle. It can be understood that the rotation angle can be the angle between two adjacent flat wire ends, such as 5 degrees, 10 degrees or 15 degrees. There is no limitation here and it can be selected according to actual conditions.

[0055] In some embodiments, the motor assembly equipment further includes a twisting device, which is used to twist the flat wire winding after expansion.
