Description

Technical Field

[0001] The invention relates to the technical field of mining machinery and equipment manufacturing, in particular to automatic assembly equipment for a mining five-phase disc motor. Background Art

[0002] Axial permanent magnet motors, also known as disc permanent magnet motors, have gained increasing attention due to their compact structure, high efficiency, and high power density. They are particularly suitable for applications that require high torque density and compact space, such as electric vehicles, renewable energy systems, gear energy storage systems, and industrial equipment.

[0003] The Chinese announcement number is: CN107800253B, which discloses an automatic assembly device for a motor, including a rotor positioning mechanism for supporting a rotor with an end cover on a workbench, a rotor clamping mechanism clamping the rotor on the rotor positioning mechanism and forming an axial limit fit, and a stator positioning mechanism for fixing the stator is also provided on the workbench. The rotor and the stator are arranged co-axially, and the driving mechanism drives the rotor and the stator to move relative to each other so that the rotor is inserted into the stator. First, the positions of the rotor and the stator are fixed, so when the rotor and the stator are assembled, the huge magnetic force on the surface of the stator core will not attract the rotor and cause damage to the magnetic steel. The driving mechanism drives the rotor and the stator to slowly approach each other until the rotor is inserted into the stator to complete the assembly of the two. During the assembly process, since the positions of the rotor and the stator are fixed by the rotor positioning mechanism and the stator positioning mechanism respectively, the two always keep the same core during the relative movement, protecting the magnetic steel;

[0004] Although the above patent ensures that the rotor and the electrons remain coaxial and protect the magnetic steel during the assembly process, considering that the assembly of the disc motor mostly relies on manual assembly of the processed parts, the manual assembly method is not only time-consuming and labor-intensive, but also causes collision damage to the parts during the assembly process, which will affect the overall performance of the motor during subsequent use. In addition, the distance between the stator and the rotor needs to be ensured during the assembly process, which is difficult to control accurately in the case of manual assembly;

[0005] In view of this, we propose an automatic assembly equipment for five-phase disc motors for mining. Summary of the invention

[0035] Embodiment 1

[0036] See also Figure 1-Figure 8As shown, this embodiment provides an automatic assembly device for a five-phase disc motor for mining, including a base 1, an electric slide rail 11 is fixedly connected to the top of the base 1, a sliding table 13 for conveying the disc motor is slidably connected to the top of the electric slide rail 11, a locking assembly 2 for locking the sliding table 13 in a fixed position is arranged on the inner side of the sliding table 13, an upper clamping ring 15 and a lower clamping ring 16 for assembling the motor rotor and the end cover are arranged above the sliding table 13, wherein: by starting the locking assembly 2, the upper clamping ring 15 and the lower clamping ring 16 are used to complete the assembly of the rotor and the end cover, and at the same time, the locking assembly 2 and the sliding table 13 are used to complete the positioning of the rotor and the stator.

[0037] like Figure 1-Figure 6 As shown, guard plates 111 are fixedly connected to both sides of the electric slide rail 11, a rack 112 is fixedly connected to the inner side of the electric slide rail 11, a platform 12 is fixedly connected to the inner side of the upper end of the guard plate 111, a plurality of gears 131 are rotatably connected to the inside of the sliding platform 13, the gears 131 are meshed and connected with the rack 112, a No. 1 threaded rod 132 is fixedly connected to the top of the center position of the gear 131, a square sliding ring 133 is threadedly connected to the outer wall of the No. 1 threaded rod 132, and a limit ring 134 is fixedly connected to the inner side of the square sliding ring 133;

[0038] Wherein: the limit ring 134 can slide up and down under the action of the No. 1 threaded rod 132 to limit the motor stators at different heights. At the same time, the sliding platform 13 moves left and right. During the movement of the sliding platform 13 left and right, the limit ring 134 will move up and down to facilitate the staff to take it.

[0039] like Figure 4-Figure 5 As shown, the outer wall of the sliding platform 13 is fixedly connected to the sliding frame 14, the inner side of the sliding frame 14 is fixedly connected to the extension rod 141, the middle top of the extension rod 141 is fixedly connected to the limit bar 143, the top outer wall of the sliding frame 14 is provided with a circular hole 142, the limit bar 143 is located on the inner side of the circular hole 142, and the extension rod 141 is rotatably connected to the top of the end away from the sliding frame 14 with a second threaded rod 1411, and the second threaded rod 1411 penetrates the sliding frame 14 The second threaded rod 1411 is arranged in the opposite direction to the thread on the outer wall of the upper end of the sliding frame 14 and the thread on the outer wall of the lower end of the sliding frame 14. The second threaded rod 1411 is threadedly connected to an upper clamping ring 15 on the outer wall of the upper end of the sliding frame 14. The inner wall of the upper clamping ring 15 is telescopically connected to a first electric clamping claw 151. The second threaded rod 1411 is threadedly connected to a lower clamping ring 16 on the outer wall of the lower end of the sliding frame 14. The inner wall of the lower clamping ring 16 is telescopically connected to a second electric clamping claw 161.

[0040] Among them: because the threads at the upper and lower ends of the second threaded rod 1411 are in opposite directions, the upper clamping ring 15 and the lower clamping ring 16 will be driven to slide in opposite directions during the rotation of the second threaded rod 1411, which makes the end cover fixed on the upper clamping ring 15 and the rotor fixed on the lower clamping ring 16 accurately positioned, and the center position of the rotor and the end cover are aligned.

[0041] like Figure 7-Figure 8 As shown, a fixed box 22 is provided in the locking device 2, and the fixed box 22 is located at the center of the sliding platform 13. An electric telescopic rod 21 is provided on the inner side of the sliding platform 13. The driving column of the electric telescopic rod 21 is fixedly connected to the outer wall of the sliding platform 13. The electric telescopic rod 21 passes through the sliding platform 13, and the electric telescopic rod 21 is slidably connected to the outer wall of the fixed box 22 and the outer wall of the sliding platform 13, wherein: a stator limiting platform 221 is fixedly connected to the top of the fixed box 22, a lifting telescopic rod 211 is fixedly connected to the top of the end of the electric telescopic rod 21 away from its driving column, and a rotor limiting platform is fixedly connected to the top of the end of the lifting telescopic rod 21 away from the electric telescopic rod 21 213, the electric telescopic rod 21 is fixedly connected with a protruding column 212 at the bottom of the end away from the driving column, and a sliding plate 231 is slidably connected to the inner side of the fixed box 22. A strip hole 2311 is provided on the outer wall of the sliding plate 231. The diameter of the protruding column 212 matches the width of the strip hole 2311. The strip holes 2311 are obliquely distributed on the surface of the sliding plate 231. A sliding rod 232 is fixedly connected to one side of the sliding plate 231. A buckle head 2321 is provided at one end of the sliding rod 232. The buckle head 2321 matches the gear groove on the outer wall of the rack 112. A spring 24 is sleeved on the outer wall of the sliding rod 232. The spring 24 is located on the outer side of the fixed box 22.

[0042] Among them: Figure 7 As shown, the electric telescopic rod 21 is always in the vertical direction of extension and retraction. At the same time, under the restriction of the sliding rod 232, the sliding plate 231 can also only slide in the horizontal direction. At this time, during the contraction process of the electric telescopic rod 21, the protruding column 212 will slide in the bar hole 2311.

[0043] It can be seen that when the disc motor needs to be automatically assembled, due to the relatively flat shape of the disc motor itself, the horizontal assembly form is easy to form an internal block between the end cover and the rotor, making it impossible to buckle the upper and lower end covers. Assembling in a stacking manner can effectively solve this problem. Moreover, because the rotor and stator of the disc motor are in a parallel state, in order to form the same central axis between the rotor and the stator, it is necessary to rely on fixing the rotor or stator, so as to adjust the other rotor or stator to ensure that the rotor and the stator are in the same center of the circle;

[0044] like Figure 1-Figure 5As shown, the staff first places the motor stator with the wire wound on the stator limiting table 221, and then places the rotor and the end cover of the motor on the inner sides of the lower clamping ring 16 and the upper clamping ring 15 respectively, and fixes the rotor and the end cover by the second electric clamp 161 and the first electric clamp 151. At this time, Figure 3 As shown, the whole device is started, and the sliding platform 13 slides from the left side to the right side under the drive of the electric slide rail 11. At this time, the sliding platform 13 will drive multiple gears 131 to slide from the left side to the right side during the sliding process. However, under the influence of the rack 112, the gears 131 will rotate along the gear groove position of the rack 112. At this time, the gear 131 will drive the No. 1 threaded rod 132 at the top thereof to rotate during the rotation process, and the No. 1 threaded rod 132 will drive the square sliding ring 133 to slide downward. At this time, the motor stator located on the stator limiting platform 221 will be restricted in the limiting ring 134;

[0045] At the same time, when the sliding platform 13 slides to the middle of the electric slide rail 11, the second threaded rod 1411 is electrically driven to rotate, and at the same time, the second threaded rod 1411 will drive the motor rotor and the end shell fixed by the upper clamping ring 15 and the lower clamping ring 16 respectively to approach each other, and keep the motor rotor and the end shell fixed to each other at the same center. At this time, the first electric clamping claw 151 inside the upper clamping ring 15 is loosened, and in the process of the sliding platform 13 sliding to the rightmost end position of the electric slide rail 11, the second threaded rod 1411 is reversed to return the upper clamping ring 15 and the lower clamping ring 16 to their original positions, that is, the lower clamping ring 16 slides to the lowermost end position of the second threaded rod 1411. At this time, the second electric clamping claw 161 is loosened and loosened at the same time, and the lifting telescopic rod 211 in the extended state drives the rotor limiting platform 213 to receive the assembled rotor and end cover and retract, and bring the assembled rotor and end cover to the same horizontal position as the stator limiting platform 221;

[0046] Then, when the sliding platform 13 slides to the rightmost side of the electric slide rail 11, the electric telescopic rod 21 is extended, and the electric telescopic rod 21 drives the lifting telescopic rod 211 to slide in the vertical position. At the same time, the protruding column 212 pulls the bar hole 2311 on the sliding plate 231 and slides in the bar hole 2311. Because the bar hole 2311 is distributed obliquely, the protruding column 212 will also give the sliding plate 231 a horizontal thrust during the sliding process in the bar hole 2311. At this time, the sliding plate 231 drives the sliding rod 232 to slide in the direction of the rack 112. At this time, the buckle head 2321 at the end of the sliding rod 232 The gear groove of the rack 112 is matched with the main sliding table 13 and the sliding table 13 is clamped, and the sliding table 13 is fixed at the rightmost end position of the electric slide rail 11. At the same time, when the protruding column 212 and the lifting telescopic rod 211 are driven by the electric telescopic rod 21, the position of the rotor limiting table 213 will be adjusted at the same time, and the position of the motor rotor can be adjusted at the same time, so that the rotor is at the same center of the stator. Then, the staff will buckle the end covers on both sides and take out the motor to complete the assembly. After the staff takes out the assembled motor, the electric telescopic rod 21 shrinks, so that the locking component 2 returns to the unlocked state, and returns to the left side driven by the electric slide rail 11 to wait for the next assembly.
