Technical Field
[0001] The present application relates to the field of motor coil manufacturing, and in particular to a large motor coil shaping processing system. Background Art
[0002] The stator coil of the motor is rather messy after winding, and the axis of the coil as a whole is different from the axis of the stator. Therefore, it is necessary to apply pressure to the surface of the inner ring of the coil for shaping to facilitate subsequent assembly work.
[0003] For example, a motor stator coil shaping device with publication number CN104218741A places the stator between two fixed outer diameter limit blocks, then the inner diameter die is extended into the inner circle of the coil, and the inner diameter die is expanded so that the inner circle of the coil is squeezed and maintained for a certain period of time so that the surface of the inner circle of the coil is regular.
[0004] With respect to the above-mentioned related technologies, after the stator is placed in the outer diameter limit block, it is necessary to adjust the position of the coil joints exposed at both ends of the stator, and perform a preliminary inspection on the inner ring of the stator coil before pressure shaping. Therefore, after the stator is placed on the outer diameter limit block, the stator needs to be rotated around its own axis at least one circle. However, the stator of a large motor is heavy, which makes it inconvenient to rotate the stator, affecting the overall efficiency of the stator coil shaping. Summary of the invention

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.
[0032] The present application embodiment discloses a large motor coil shaping processing system, referring to Figure 1 , including a machine 1, a slideway 3 is attached to one side of the machine 1 and is detachably connected, a stator plate 4 is placed on the slideway 3, and a plurality of universal balls are arranged on the bottom surface of the stator plate 4 so that the stator plate 4 can move stably. Two circumferential adjustment rollers 5 are connected to the upper surface of the stator plate 4 for damping rotation, and the outer wall of the stator circumference is placed on the two circumferential adjustment rollers 5, so that after applying appropriate force to the stator, the stator can rotate around its own axis. The machine 1 is provided with a positioning device 51 for moving the stator to a specified position and an inner ring shaping part 2 for shaping the inner wall of the stator coil at the specified position, and the inner ring shaping part 2 can refer to the existing structure in the background technology.
[0033] Reference Figure 2 and Figure 3 The machine 1 is provided with a platform opening 32 on the vertical side surface corresponding to the slideway 3, and the platform opening 32 penetrates the upper surface of the machine 1. A loading and unloading plate oil cylinder 47 is detachably connected in the platform opening 32, and a loading and unloading plate 46 is detachably connected to the upper end of the power rod of the loading and unloading plate oil cylinder 47. The upper surface of the loading and unloading plate 46 can be flush with the upper surface of the slideway 3, and the loading and unloading plate 46 can be slidably connected to the vertical side surface of the slideway 3 in the vertical direction. A side bar 48 is fixedly connected to the upper surface of the loading and unloading plate 46 away from the slideway 3. After the stator plate 4 moves from the slideway 3 to the loading and unloading plate 46, it can abut against the side bar 48. At the same time, a positioning groove 49 is provided on the surface of the side bar 48 facing the stator plate 4, and the positioning groove 49 penetrates the upper surface of the side bar 48. A positioning block 31 that can be slidably inserted into the positioning groove 49 is fixedly connected to the periphery of the stator plate 4, so that the position of the stator plate 4 on the loading and unloading plate 46 is fixed.
[0034] Reference Figure 2 and Figure 3 The positioning device 51 includes two chain plate conveyors 52 installed in the platform mouth 32. The chain plate conveyors 52 are used for horizontal and radial transmission of the stator. The upper and lower material plates 46 are located between the two chain plate conveyors 52. When the upper and lower material plates 46 move down and pass between the two chain plate conveyors 52, the opposite sides of the stator plate 4 abut against the upper surfaces of the two chain plate conveyors 52, and then the stator plate 4 is driven away from the slideway 3. The inner wall of the platform mouth 32 away from the slideway 3 is detachably connected to the limit plate 57. The platform mouth 32 is located between the two chain plate conveyors 52 and is installed with a lifting cylinder 41. The top of the power rod of the lifting cylinder 41 is detachably connected to the lifting plate 42, and the plate distance sensor 43 is detachably connected to the hole on the upper surface of the lifting plate 42. Two axis fixing plates 58 are slidably connected to the inner wall of the stage mouth 32, and the stator is located between the two axis fixing plates 58. Two axis fixing plate cylinders 59 are detachably connected to the inner wall of the stage mouth 32, and the power rods of the two axis fixing plate cylinders 59 are detachably connected to the two axis fixing plates 58 one by one.
[0035] After the positioning block 31 abuts against the limit plate 57, the plate distance sensor 43 is just opposite to the hole on the lower surface of the stator plate 4. At this time, the distance value detected by the plate distance sensor 43 is within the distance range preset in the external controller, so that the external controller can stop the operation of the chain conveyor 52, and then the lifting cylinder 41 drives the lifting plate 42 to move up a predetermined distance, and then the axis fixing plate cylinder 59 drives the two axis fixing plates 58 to approach a certain distance, so that the stator can adjust its position along its own axis direction.
[0036] Reference Figure 4 The positioning device 51 also includes a clamping plate 53 that moves in the vertical direction. The clamping plate 53 is stably moved via the guide rod and hydraulic cylinder provided on the machine platform 1. The clamping plate 53 is slidably connected to two clamping jaws 54 along the transmission direction of the chain plate conveyor 52. The two clamping jaws 54 are detachably connected to an arc block 44 near each other. The arc surfaces of the two arc blocks 44 are attached to the circumferential outer wall of the stator to stably clamp the stator. The bottom end of one clamping jaw 54 is provided with a rod distance sensor 45 that is directly opposite to the other clamping jaw 54. The upper surface of the clamping jaw plate 53 is rotatably connected to a bidirectional lead screw 55. The bidirectional lead screw 55 is penetrated and threadedly connected to the two clamping jaws 54. The two clamping jaws 54 are located at equal distances on both sides of the center point of the bidirectional lead screw 55. The thread directions on both sides of the center point of the bidirectional lead screw 55 are opposite. The clamping jaw plate 53 is detachably connected to a lead screw motor 56 whose output shaft is coaxially detachably connected to the bidirectional lead screw 55. The lead screw motor 56 can be a servo motor with a torque sensor.
[0037] When the shaft fixing plate 58 moves away from each other, the clamping plate 53 moves down so that the stator is located between the two clamping jaws 54, and then the screw motor 56 drives the bidirectional screw 55 to rotate, so that the two clamping jaws 54 are close to each other, so that the arc surface of the arc block 44 abuts against the stator. When the screw motor 56 detects that the torque reaches the preset value in the external controller, the rod distance sensor 45 detects the distance between the bottom ends of the two clamping jaws 54. When the distance value detected by the rod distance sensor 45 is within the preset range in the external controller, the clamping plate 53 moves up a predetermined distance, and then the inner ring shaping part 2 shapes the inner ring of the stator.
[0038] The implementation principle of a large motor coil shaping processing system of the embodiment of the present application is as follows: the stator is placed on two circumferential adjustment rollers 5 for rotation, so that the inner wall of the stator can be conveniently inspected. After the inspection is completed, the stator plate 4 is pushed onto the upper and lower material plates 46, and then the upper and lower material plates 46 are moved down, so that the stator plate 4 moves to the chain plate conveyor 52, and the chain plate conveyor 52 drives the stator plate 4 to move to abut against the limit plate 57, and then the lifting plate 42 abuts against the stator plate 4 and moves up a specified distance, and the two axis fixed plates 58 adjust the position in the axial direction of the stator, and then the clamping claw plate 53 moves down, and the two clamping claws 54 are close to clamp the stator, and then the stator is driven to move up, so that the inner ring shaping part 2 shapes the inner ring of the stator.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
