Description

Technical Field

[0001] This application relates to the technical field of motor assembly, specifically to motor stator and rotor assembly equipment. Background Art

[0002] A motor mainly consists of two parts: a stator and a rotor. By installing the rotor inside the stator, the entire motor can rotate. Since the rotor rotates at high speed in the middle of the stator, the installation of the motor stator and rotor is very crucial. During installation, it is necessary to ensure the coaxiality of the stator and rotor so as to ensure that the peripheral gaps between the stator and rotor are the same during installation.

[0003] After retrieval, for example, the patent with the publication number CN213027748U specifically discloses a small-power motor rotor and stator assembly device. This patent fixes the rotor through a positioning cylinder, then fixes the stator through a fixing seat, and finally assembles the stator and rotor through a lifting mechanism.

[0004] However, during the assembly process, due to inaccurate calibration of the alignment system, insufficient machining accuracy of the rotor, and deformation of the rotor caused during transportation, etc., collisions may occur when the rotor and stator are assembled, resulting in misalignment problems, which are likely to damage the stator and increase the scrap rate. Therefore, it is necessary to provide motor stator and rotor assembly equipment to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide motor stator and rotor assembly equipment, which achieves the prevention of collisions during the assembly of the stator and rotor, damage to the stator, and an increase in the scrap rate.

[0007] The technical solution adopted by this application to solve its technical problems is: Motor stator and rotor assembly equipment, including:

[0012] A driving mechanism, which is arranged at the upper end of the pneumatic chuck, and the driving mechanism is used to control the up and down movement of the pneumatic chuck;

[0013] A calibration mechanism, which is arranged on one side of the fixing mechanism, and the calibration mechanism has:

[0014] A support rod, which is installed at the upper end of the assembly table. An extension plate is fixedly installed at the upper end of the support rod. The other end of the extension plate is fixedly installed with a concave ring. An opening is formed through the lower end of the concave ring. There is a clearance fit between the opening and the rotor, and the opening is coaxially arranged with the pneumatic chuck.

[0015] Further, the concave ring is composed of at least two groups of inclined plates. The connection end of the inclined plate and the extension plate has elasticity. A retaining ring is fixedly installed at the lower end of the extension plate. The retaining ring is arranged outside the concave ring. A contact switch is fixedly installed on the inner wall of the retaining ring. The number of the contact switches is the same as that of the inclined plates.

[0016] Further, the driving mechanism has a top plate. At least two groups of fixing rods are fixedly installed at the lower end of the top plate. A first cylinder is fixedly installed at the upper end of the top plate. The telescopic shaft of the first cylinder faces downward and penetrates through the top plate. A movable plate is fixedly installed at the lower end of the first cylinder. The pneumatic chuck is fixed at the lower end of the movable plate.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0033] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0034] As Figure 1 - Figure 2 shown, this application provides a motor stator-rotor assembly device, including a box body 1. An assembly table 11 is arranged inside the box body 1. A fixing mechanism 2 is arranged at the upper end of the assembly table 11. The fixing mechanism 2 is used to fix the stator 5 to be assembled. At the same time, a pneumatic chuck 7 is arranged directly above the fixing mechanism 2. The pneumatic chuck 7 is used to fix the rotor 6 to be assembled. In this application, the pneumatic chuck 7 is a prior art, and specific details can be found in relevant materials and will not be elaborated here.

[0035] To better control the up and down movement of the pneumatic chuck 7, a driving mechanism 4 is arranged at the upper end of the pneumatic chuck 7. The driving mechanism 4 has a top plate 41. A plurality of fixing rods 42 are fixedly installed at the lower end of the top plate 41. The top plate 41 is supported above the box body 1 through the fixing rods 42. At the same time, a first cylinder 43 is fixedly installed at the upper end of the top plate 41. The telescopic shaft of the first cylinder 43 faces downward and penetrates through the top plate 41. The lower end of the first cylinder 43 is fixedly installed with a movable plate 45. The pneumatic chuck 7 is fixed to the lower end of the movable plate 45. Therefore, the first pneumatic cylinder 43 can push the movable plate 45 downward, driving the pneumatic chuck 7 and the rotor 6 downward to be assembled with the stator 5.

[0036] At the same time, two sliding rods 44 are fixedly installed at the upper end of the movable plate 45. The sliding rods 44 are located on both sides of the telescopic shaft of the first cylinder 43. The sliding stability of the movable plate 45 can be improved through the sliding rods 44.

[0037] As Figure 3 shown, the fixing mechanism 2 has a second cylinder 21. The output end of the second cylinder 21 is arranged upward and fixedly installed with a push rod 22. The push rod 22 is coaxially arranged with the pneumatic chuck 7. At the same time, a fixing ring 23 is fixedly installed at the upper end of the second cylinder 21. The fixing ring 23 is arranged with the push rod 22 as the center. A plurality of clamping plates 24 are hinged on the outer side of the fixing ring 23. A step for placing the stator 5 is arranged on the clamping plate 24. At the same time, the clamping plate 24 is inclined outward in the normal state. The central end of the clamping plate 24 is hinged with a connecting plate 25. The other end of the connecting plate 25 is hinged to the upper end of the push rod 22;

[0038] Therefore, when clamping the stator 5, place the stator 5 between the clamping plates 24. Then start the second cylinder 21 to contract, driving the push rod 22 downward. The push rod 22 drives the clamping plates 24 to rotate inward through the connecting plate 25, thereby clamping and fixing the stator 5. It should be noted that the fixed stator 5 and the push rod 22 are coaxially arranged;

[0039] When the stator 5 needs to be taken out, control the second cylinder 21 to push the push rod 22 upward until the connecting plate 25 is horizontal. At this time, the clamping plates 24 are inclined outward, and the stator 5 can be taken out.

[0040] As Figure 3 - Figure 4 shown, in order to prevent the rotor 6 and the stator 5 from colliding during assembly, a calibration mechanism 3 is provided on one side of the second cylinder 21. The calibration mechanism 3 has a support rod 31 fixedly installed at the upper end of the assembly table 11. The support rod 31 is located on one side of the second cylinder 21, and an extension plate 32 is fixedly installed at the upper end of the support rod 31. The other end of the extension plate 32 is fixedly installed with a concave ring 33. An opening (not marked in the figure) is formed through the lower end of the concave ring 33. The opening has a clearance fit with the rotor 6, and the opening is coaxially arranged with the pneumatic chuck 7 and the push rod 22. Therefore, when the rotor 6 moves downward with the driving mechanism 4, it will pass through the opening of the concave ring 33;

[0041] It should be noted that the concave ring 33 is composed of multiple groups of inclined plates 34, and the connecting end of the inclined plate 34 and the extension plate 32 has elasticity. Therefore, the inclined plate 34 will tilt outward when subjected to pressure and reset when the pressure disappears.

[0042] At the same time, a retaining ring 35 is fixedly installed at the lower end of the extension plate 32. The retaining ring 35 is arranged outside the concave ring 33, and a contact switch 36 is fixedly installed on the inner wall of the retaining ring 35. The number of the contact switches 36 is the same as that of the inclined plates 34, and the contact switch 36 is electrically connected to the first cylinder 43. In this application, the contact switch 36 is the closing switch of the first cylinder 43. Therefore, when the contact switch 36 is triggered, the first cylinder 43 will stop running;

[0043] And a pressure rod 38 is rotatably connected to the outer side end of each group of inclined plates 34. The other end of the pressure rod 38 is located outside the contact switch 36. In order to keep the pressure rod 38 stable, a support frame 37 is fixedly installed at the lower end of the extension plate 32. The support frame 37 is sleeved outside the pressure rod 38. Therefore, when the inclined plate 34 is subjected to pressure, it will push the pressure rod 38 outward along the support frame 37.

[0044] To sum up: When assembling the stator 5 and the rotor 6, first fix the stator 5 on the fixing mechanism 2, then fix the rotor 6 on the pneumatic chuck 7, and then start the first cylinder 43 to push the rotor 6 downward and pass through the concave ring 33;

[0045] At this time, if the rotor 6 does not touch the inclined plate 34 when it descends, the rotor 6 will fall normally and complete the assembly with the stator 5;

[0046] If the rotor 6 collides with the inclined plate 34, it will push the inclined plate 34 outwards. The inclined plate 34 will drive the pressure rod 38 to move outwards and squeeze the contact switch 36, causing the contact switch 36 to open and close the first cylinder 43. Therefore, at this time, the rotor 6 stops descending. Subsequently, the operator comes to control the first cylinder 43 to reset and takes out and replaces the rotor 6, thereby preventing the stator 5 and the rotor 6 from colliding during assembly and damaging the stator 5, increasing the scrap rate.

[0047] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
