Description

Technical Field

[0001] The present invention relates to the field of motor assembly, and in particular to a motor stator and rotor assembly device. Background Art

[0002] In the assembly of stators and rotors for medium and large motors, precise positioning of the stator and rotor is a key step in ensuring stable motor performance.

[0003] Traditional motor stator and rotor assembly equipment often relies on an additional power drive system (such as an electric push rod or hydraulic device) to drive a positioning device to calibrate the stator or rotor position when positioning the stator. The specific process involves securing the rotor and positioning the stator. After positioning, the stator is clamped and then gradually inserted into the rotor to complete the stator-rotor assembly. To prevent the rotor from colliding with the positioning device, the positioning device must be reset after calibration. Both the operation and reset of the positioning device in existing technologies require an additional power source, which not only increases manufacturing costs but also leads to higher energy consumption during operation, increasing the cost of equipment use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a motor stator and rotor assembly device.

[0006] As an improvement, the stator clamping mechanism includes a splint moving in the assembly mechanism, the stator automatic positioning mechanism includes several insertion rods passing through the splint, the insertion rods are respectively provided with abutment rings and transmission rings, the transmission ring is provided with several sliding rods, and the sliding rods are sleeved with sliding blocks. One of the sliding rods is sleeved with a spring two that abuts on the sliding block, and several sliding blocks are provided on the opposite surfaces of the sliding blocks. The ends of the several folding rods are jointly fixed to the connecting ring one, and the connecting ring one is provided with a connecting ring two that is slidably connected to the folding rod one on the side away from the stator body. The connecting ring one and the connecting ring two are jointly provided with a hinge part, and the splint is provided with a circular through groove four, and the through groove four inner wall is provided with several extension grooves, and the extension groove is provided with a limit block at one end of the stator body. Several folding rods two are fixed on the end surface of the connecting ring two sides, the bending rod of the folding rod two is located in the extension groove, and the end passes through the limit block, and the bending rod outer sleeve has a spring three that abuts the limit block.

[0007] As an improvement, a groove is provided on the end face of the splint close to the butt ring, which is located at the insertion rod. When the butt ring moves away from the stator body, it can be located in the groove. A spring is provided on the outer sleeve of the insertion rod, which is located between the butt ring and the inner wall of the groove. When the splint moves toward the position of the stator body, the groove moves toward the butt ring, and the second connecting ring moves toward the first connecting ring. The two hinged rods of the hinge are folded in half, and the folding point contacts the inner wall of the stator body. A visual monitoring device for observing the contact situation is provided on the folding rod.

[0008] As an improvement, several sliding rods 2 passing through the connecting ring 1 are fixedly connected to the connecting ring 2. When the assembly mechanism drives the stator body to move and sleeve on the rotor body, the rotor body abuts against the sliding rod 2 and pushes the sliding rod 2 to move outside the stator body. The sliding rod 2 pulls the connecting ring 1 to move through the hinge, thereby causing the connecting ring 1 and the connecting ring 2 to move toward the splint to retreat and make way.

[0009] As an improvement, the rotor fixing mechanism includes a support located on the main body of the equipment, an electric telescopic rod three is slidingly provided in the support, the telescopic end of the electric telescopic rod three is provided with a pin, the pin abuts against the rotor body, a rack is provided at the bottom end of the electric telescopic rod three, a drive motor two is provided in the support, and the rack is driven by the drive motor two.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] 1. The present invention is provided with an automatic stator positioning mechanism. During the entire process of positioning and subsequently resetting the stator body, no additional power source is required. The precise positioning of the stator body can be achieved only through the interaction between mechanical structures, such as the linkage of the retaining ring, transmission ring, folding rod and spring, which effectively simplifies the power system design of the equipment and reduces the energy consumption and maintenance cost of the equipment.

[0015] 2. The transfer mechanism can carry two sets of rotor bodies and stator bodies. Workers can first place one set of components to be assembled on the transfer mechanism, lower it and move it before placing the other set, thus realizing the alternating assembly of the two sets of components. This greatly improves the assembly efficiency of the motor stator and rotor, reduces the time wasted due to frequent loading and unloading, and makes the production process more compact.

[0016] 3. The stator clamping mechanism works in conjunction with the stator automatic positioning mechanism. When the clamping plate moves, the retaining ring drives the transmission ring and other components to make the hinge contact with the inner wall of the stator body. The staff observes the contact situation and adjusts the height through the visual monitoring device to ensure the accurate position of the stator body before clamping. This effectively avoids assembly errors caused by stator position deviation, improves the success rate of stator and rotor assembly, and ensures the stable performance of the motor.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 As shown:

[0030] A motor stator and rotor assembly device includes a device body 1, on which a rotor body 4 and a stator body 5 are provided. The device body 1 is provided with an assembly mechanism 6 that can drive the stator body 5 to move toward the rotor body 4 to complete the stator and rotor assembly. A stator clamping mechanism 7 that can clamp the stator body 5 is slidably provided within the assembly mechanism 6. A bottom frame 2 is provided at the bottom of the device body 1. A transfer mechanism 3 that can carry two sets of rotor bodies 4 and stator bodies 5 is slidably provided within the bottom frame 2. The transfer mechanism 3 can drive the rotor body 4 and the stator body 5 to move up and down. The stator clamping mechanism 7 is provided with a stator automatic positioning mechanism 8 that can automatically determine the position of the stator body 5. After the stator clamping mechanism 7 moves and drives the stator automatic positioning mechanism 8 to center the stator body 5, the assembly mechanism 6 drives the stator clamping mechanism 7 and the stator body 5 to move and sleeve the stator body 5 on the rotor body 4. During the movement and sleeve process of the stator body 5, the stator automatic positioning mechanism 8 abuts against the rotor body 4 and moves back and forth. The equipment main body 1 is provided with a rotor fixing mechanism 9 that fixes the rotor body 4 by cooperating with the equipment main body 1.

[0031] The working principle of the present invention is as follows: the staff places a group of rotor bodies 4 and stator bodies 5 on the transfer mechanism 3 in the raised state through lifting equipment or manually, lowers the transfer mechanism 3 and after it is lowered into place, manually pushes the transfer mechanism 3 to one side, and raises the transfer mechanism 3 again after it is in place, and places another group of rotor bodies 4 and stator bodies 5, and the previously placed rotor bodies 4 and stator bodies 5 are located in the equipment main body 1, and the stator clamping mechanism 7 is started to clamp the stator body 5. During the process, the stator automatic positioning mechanism 8 detects the position of the stator body 5, and the staff manually adjusts it to the stator body 5, and then starts the rotor fixing mechanism 9 and cooperates with the staff manually to stably fix the rotor body 4 on the equipment main body 1. At this time, the stator body 5 and the rotor body 4 are in a coaxial state, and the assembly mechanism 6 is started to drive the stator body 5 to be sleeved outside the rotor body 4 to complete the assembly of the stator and rotor.

[0032] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 , as shown in the attached figure:

[0033] The bottom frame 2 includes a frame body 201, a track 203 is provided in the frame body 201, and the transfer mechanism 3 includes a movable base plate 301 that moves on the frame body 201, a support plate 303 is provided on the movable base plate 301, a second through slot 304 is provided on the support plate 303, and a cavity 305 is provided on the side walls at both ends of the through slot 304, a slider 306 is slidably provided in the second through slot 304, and side brackets 311 are provided at both ends of the slider 306, and a bottom bracket 312 that can support the rotor body 4 and the stator body 5 is provided on the side bracket 311, and a lifting device that can drive the slider 306 to move up and down is provided in the cavity 305;

[0034] The lifting device includes an electric telescopic rod 307 respectively disposed in the two cavities 305. The bottom end of the electric telescopic rod 307 is hinged to the movable base plate 301, and the top end is hinged to the side wall of the slider 306. The movable base plate 301 is provided with a drive motor 308 located below the slider 306. The drive motor 308 is provided with a screw rod 309. The bottom end of the slider 306 is provided with a screw hole 310 threadedly connected to the screw rod 309.

[0035] Both ends of the frame body 201 are provided with a side plate 204 with an arc-shaped end surface at one end. The end of the movable bottom plate 301 is provided with a vertical rod 313, the top of the vertical rod 313 is provided with a handle 1 314, the end of the handle 1 314 is provided with a connecting rod 315, and the end of the connecting rod 315 is provided with a handle 2 316 that is slidably connected to the arc-shaped end surface of the side plate 204;

[0036] Limiting plates 202 for limiting the position of the movable bottom plate 301 are provided at both ends of the frame body 201 adjacent to the side plates 204 . Rollers 302 rolling on the tracks 203 are provided at the bottom of the movable bottom plate 301 .

[0037] Working principle of transfer mechanism 3: The staff manually pulls the movable base plate 301 to one side through handle 2 316. After it is in place, a lifting device or manual operation is used to place a set of rotor bodies 4 and stator bodies 5 on the bottom support 312. Then the movable base plate 301 is pulled to the other side. After it is in place, another set of rotor bodies 4 and stator bodies 5 are placed on the bottom support 312. Then the drive motor 1 308 is started to drive the screw rod 309 to rotate forward. The screw rod 309 drives the side bracket 311 to move upward through the slider 306. During this process, the slider 306 drives the electric telescopic rod 1 307 to extend. When the screw rod 309 is disengaged from the slider 306, the electric telescopic rod 1 307 is started to drive the side bracket 311 to move upward. After it is in place, the stator and rotor assembly procedure can be carried out.

[0038] A drive motor 308 and a screw rod 309 are provided to cooperate with the electric telescopic rod 307 to work. In a specific implementation of the present invention, when the bottom end of the electric telescopic rod 307 is lower than the lowest point of the slider 306, only the electric telescopic rod 307 can be used to achieve lifting. When the bottom end of the electric telescopic rod 307 and the lowest point of the slider 306 are at the same height, when the slider 306 initially moves upward and cannot be lifted due to the large force angle applied by the electric telescopic rod 307, the drive motor 308 and the screw rod 309 can cooperate to lift the slider 306 to a certain height.

[0039] When assembling the stator and rotor, the slider 306 needs to be moved down to avoid collision. After assembly, the slider 306 is moved up again to support the assembled motor semi-finished product, and then the slider 306 is moved down again. After it is in place, the movable base plate 301 is pulled to one side, and then the slider 306 is lifted. At this time, the rotor body 4 and the stator body 5 of another group can be assembled. At the same time, the assembled motor semi-finished product is unloaded and the rotor body 4 and the stator body 5 are replaced.

[0040] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 9 , Attachment Figure 10 As shown:

[0041] The equipment body 1 includes an equipment base 101, on which is provided a rotor clamping device 102 capable of clamping and fixing the rotor body 4. In the prior art, the rotor clamping device 102 includes a driving rotation device and a machine tool fixture. The machine tool fixture can clamp the shaft of the rotor body 4. In conjunction with the rotor fixing mechanism 9, the rotor clamping device 102 can clamp the rotor body 4 more stably. The equipment base 101 is located directly above the bottom frame 2 and is provided with a through slot 103 through which the rotor body 4 and the stator body 5 can pass.

[0042] The assembly mechanism 6 includes a drive device 601 located on the equipment base 101. The drive device 601 is provided with screws 602 located at both ends of the through slot 103. The two screws 602 are commonly provided with an assembly frame 603. The side surface of the assembly frame 603 is provided with a through slot 3 604 for allowing the rotor body 4 to pass through.

[0043] The stator clamping mechanism 7 includes a clamping plate 702 that moves within the assembly mechanism 6, and the stator automatic positioning mechanism 8 includes a plurality of insertion rods 801 that pass through the clamping plate 702. The insertion rods 801 are provided with a ring 802 and a transmission ring 803 at both ends. The transmission ring 803 is provided with a plurality of slide rods 805, and a slide block 806 is sleeved on the slide rod 805. One of the slide rods 805 is sleeved with a spring 807 that abuts against the slide block 806. The opposite surfaces of the plurality of slide blocks 806 are provided with a folding rod 808. The ends of the plurality of folding rods 808 are fixedly connected to a connecting ring 809. The connecting ring 809 is away from A second connecting ring 810 is provided on one side of the stator body 5, which is slidably connected to the first folding rod 808. The first connecting ring 809 and the second connecting ring 810 are jointly provided with a hinge 811. The clamping plate 702 is provided with a fourth circular through-slot 706. The inner wall of the fourth through-slot 706 is provided with a plurality of extension slots 704. The extension slots 704 are provided with a limit block 705 at one end away from the stator body 5. A plurality of second folding rods 813 are fixedly connected to the side end surface of the second connecting ring 810. The bent rods of the second folding rods 813 are located in the extension slots 704, and the ends thereof pass through the limit block 705. The outer sleeve of the bent rods has a third spring 814, one end of which abuts the limit block 705.

[0044] A groove 703 is provided on the end surface of the clamping plate 702 near the anvil 802, which is located at the insertion rod 801. When the anvil 802 moves away from the stator body 5, it can be located in the groove 703. The insertion rod 801 is covered with a spring 1 804 located between the anvil 802 and the inner wall of the groove 703. When the clamping plate 702 moves toward the position of the stator body 5, the groove 703 moves toward the anvil 802, and the second connecting ring 810 moves toward the first connecting ring 809. The two hinged rods of the hinge 811 fold in half, and the folding point contacts the inner wall of the stator body 5. The folding rod 1 808 is provided with a visual monitoring device 815 for observing the contact situation.

[0045] Several second slide bars 812 passing through the first connecting ring 809 are fixedly connected to the second connecting ring 810. When the assembly mechanism 6 drives the stator body 5 to move and sleeve on the rotor body 4, the rotor body 4 abuts against the second slide bars 812 and pushes the second slide bars 812 to move outward from the stator body 5. The second slide bars 812 pull the first connecting ring 809 to move through the hinge 811, thereby causing the first connecting ring 809 and the second connecting ring 810 to move toward the clamping plate 702 to retreat and make way.

[0046] After the stator body 5 and the rotor body 4 are moved up to their proper positions, the electric telescopic rod 2 701 is started to extend and drive the splint 702 to move toward the stator body 5. When the stator body 5 moves a certain distance, the stator body 5 drives the stator automatic positioning mechanism 8 to extend and contact the inner wall of the stator body 5. The staff observes the contact between the hinge 811 and the inner wall of the stator body 5 in real time through the visual monitoring device 815. If any hinge 811 is not in contact with the inner wall of the stator body 5, the staff is required to adjust the height of the stator body 5 and the rotor body 4 through the transfer mechanism 3, and continue to extend the electric telescopic rod 2 701 during the adjustment process until all the hinges 811 are in contact with the inner wall of the stator body 5. After that, the splint 702 clamps the stator body 5 through the assembly frame 603, and the transfer mechanism 3 moves down and starts. The dynamic driving device 601 rotates forward through the assembly frame 603 to drive the stator body 5 to move toward the rotor body 4. When the stator body 5 and the rotor body 4 begin to be assembled, the rotor body 4 can automatically push the stator automatic positioning mechanism 8 out of the stator body 5. After the assembly is completed, the driving device 601 reverses to drive the assembly frame 603 back to its position, and then the transfer mechanism 3 moves up to contact the semi-finished motor, and the electric telescopic rod 2 701 is retracted to drive the clamping plate 702 back to its position. During the process, the distance between the clamping plate 702 and the stator body 5 increases, so that the stator automatic positioning mechanism 8 gradually returns to its position. When the stator automatic positioning mechanism 8 is separated from the rotor body 4, the stator automatic positioning mechanism 8 can move with the clamping plate 702. After reaching the position, the clamping plate 702 and the stator automatic positioning mechanism 8 are both reset.

[0047] The visual monitoring device 815 is a conventional technology, specifically a camera, and the staff can observe the specific situation through the display screen;

[0048] Working process of stator automatic positioning mechanism 8:

[0049] Step 1: The clamping plate 702 moves a certain distance toward the stator body 5, and the stator body 5 contacts and squeezes the anvil 802. At this time, the anvil 802 stops, that is, the connecting ring 1 809 stops moving, and the clamping plate 702 gradually moves away from the transmission ring 803. The limit block 705 drives the connecting ring 2 810 to move toward the connecting ring 1 809 through the spring 3 814, and the hinge 811 bends. When all the hinges 811 are in contact with the inner wall of the stator body 5, the hinge 811 bends into place. When the clamping plate 702 continues to move, the spring 3 814 is gradually compressed;

[0050] Step 2: During assembly, the rotor body 4 is inserted into the stator body 5. During this process, the shaft of the rotor body 4 contacts the second slide bar 812 and pushes the second connecting ring 810 to move in the opposite direction through the second slide bar 812. The second connecting ring 810 pulls the hinge 811 to restore and pulls the first connecting ring 809 to move through the hinge 811. At this time, the second spring 807 and the third spring 814 continue to be compressed, that is, the sliding block 806 moves on the first slide bar 805, and the second folding rod 813 moves in the limit block 705 until the stator body 5 moves into place;

[0051] Step 3: The clamping plate 702 moves in the opposite direction and disengages from the stator body 5. The anvil 802 tends to return to its original position relative to the clamping plate 702 under the action of the first spring 804, and the sliding block 806 is stationary under the action of the second spring 807. That is, the first connecting ring 809 pulls the second connecting ring 810 through the hinge 811, but the second sliding bar 812 is still in contact with the rotor body 4 under the action of the third spring 814. That is, the first connecting ring 809 is pulled by the second connecting ring 810 through the hinge 811. Until the anvil 802 is completely reset, the state of the stator automatic positioning mechanism 8 is the same as that after the end of step 3 because the second spring 807 and the third spring 814 have not yet completed the reset.

[0052] Step 5: The clamping plate 702 continues to move in the opposite direction, and the second slide bar 812 is still in contact with the rotor body 4. During this process, the sliding block 806 gradually approaches the transmission ring 803 and the limit block 705 gradually moves away from the second connecting ring 810, causing the second spring 807 and the third spring 814 to gradually rebound. When the sliding block 806 and the limit block 705 are reset, the clamping plate 702 continues to move in the opposite direction. At this time, the second slide bar 812 can be disengaged from the rotor body 4, and the assembled semi-finished motor can finally be unloaded.

[0053] In addition to the necessary stator and rotor assembly process in the prior art, the stator automatic positioning mechanism 8 in the present invention does not require an additional power source in the entire process of realizing the position positioning function of the stator body 5 and the subsequent resetting.

[0054] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 6 , Attachment Figure 7 As shown:

[0055] The rotor fixing mechanism 9 includes a support 901 located on the main body 1 of the device, and an electric telescopic rod 3 904 is slidingly provided in the support 901. The telescopic end of the electric telescopic rod 3 904 is provided with a pin 905, which abuts against the rotor body 4. A rack 906 is provided at the bottom end of the electric telescopic rod 3 904, a drive motor 2 902 is provided in the support 901, and a worm 903 is provided at the end of the drive motor 2 902. A rotating shaft 907 is rotatably provided in the support 901, and gears 908 are provided at both ends of the rotating shaft 907, which respectively mesh with the rack 906 and the worm 903.

[0056] After the stator body 5 is positioned, the staff needs to manually install the rotor body 4 onto the equipment body 1, and then start the drive motor 2 902 to drive the electric telescopic rod 3 904 to move toward the rotor body 4, and at the same time start the electric telescopic rod 3 904 to extend until the ejector pin 905 abuts against the rotor body 4. After the assembly is completed, the rotor fixing mechanism 9 needs to be reset first to avoid the rotor fixing mechanism 9 and the assembly mechanism 6 resetting at a slow speed, which may cause the rotor body 4 to be ejected from the stator body 5.

[0057] When the present invention is specifically implemented:

[0058] The staff placed the rotor body 4 and stator body 5 on the base 312, raised the transfer mechanism 3, and activated the stator clamping mechanism 7. During the movement, the stator body 5 pressed against the collar 802. When all the hinges 811 contacted the inner wall of the stator body 5, the clamping plate 702 clamped the stator body 5 through the assembly frame 603. During this process, the staff observed the contact situation using the visual monitoring device 815 and adjusted the height of the transfer mechanism 3, ultimately determining the height position of the stator body 5 and aligning the stator body 5. The rotor fixing mechanism 9 was activated to abut and fix the ejector pin 905 against the rotor body 4. At this point, the stator body 5 and the rotor body 4 are coaxial. Finally, the assembly mechanism 6 is started to drive the assembly frame 603 and the stator body 5 to move toward the rotor body 4 to complete the sleeve assembly. After assembly, the driving device 601 is reversed and returned to its original position. The transfer mechanism 3 moves up to support the semi-finished motor, and the electric telescopic rod 701 is retracted to return the clamping plate 702 to its original position. The stator automatic positioning mechanism 8 is reset under the action of the spring. Then the transfer mechanism 3 is moved to unload the semi-finished motor and replace the rotor body 4 and stator body 5 to be assembled to enter the next round of assembly process.
