Description

Technical Field

[0001] This application relates to the technical field of rotor circumferential surface cleaning equipment, and in particular to a rotor circumferential surface cleaning carrier. Background Technology

[0002] In the production of subway traction motors, one step requires grinding and cleaning the circumferential surface of the rotor. With rapid urbanization, the demand for subway traction motors is increasing daily, placing higher demands on their manufacturing processes. Among these challenges, efficiently and accurately completing rotor surface processing has become a key factor in improving overall production efficiency. Against this backdrop, various auxiliary devices and technologies have emerged, not only improving the level of automation in production but also significantly enhancing product quality and work efficiency.

[0003] Under relevant technologies, two methods are typically used in actual production to address the challenges of machining the rotor's circumferential surface: one is to manually rotate the heavy rotor while using fixed tools for grinding; the other is to have operators walk around the stationary rotor to perform surface treatment. For the former, while using external force to rotate the massive rotor component achieves a degree of mechanization, the large rotor mass makes manual intervention still extremely arduous. The latter relies entirely on manual adjustment of position and angle, a time-consuming process that easily leads to fatigue and affects precision control. Additionally, there is a method based on traditional clamping, using simple mechanical structures to stabilize the rotor before performing localized fine finishing work; however, this method lacks flexibility and is difficult to adapt to changes in product specifications and sizes.

[0004] Regarding the aforementioned technologies, these common practices generally suffer from a problem—the lack of an effective load-bearing and power transmission mechanism to support the convenient self-spinning function of large workpieces while ensuring good adaptability. This places significant pressure on workers in terms of both physical exertion and time costs, and cannot meet the requirements of high-frequency continuous operation. Therefore, there is an urgent need to design a specialized carrier that can automatically drive the rotor to rotate and quickly position it to overcome the shortcomings of the existing process. Utility Model Content

[0005] In order to automatically drive the rotor to rotate and quickly position it, this application proposes a rotor circumferential surface cleaning carrier.

[0006] This application provides a rotor circumferential surface cleaning carrier, which adopts the following technical solution:

[0007] A rotor circumferential surface cleaning carrier includes a frame, a support assembly, and a drive assembly;

[0008] The support assembly is mounted on the frame. The support assembly includes two support members spaced apart in a first direction. Each support member includes two support rollers spaced apart in a second direction. The support rollers are connected to the frame via a mounting base. There is a support gap between the two support rollers in the second direction. The support rollers are rotatably connected to the mounting base. The support rollers are parallel to the first direction along the rotation axis of the mounting base.

[0009] The drive assembly is disposed on one side of the mounting base, and the drive assembly includes a drive element, a second gear, and a third gear;

[0010] Two support rollers of each support member are rotatably connected to the mounting base via a first rotating shaft. A second gear is fixedly sleeved on each of the first rotating shafts. A third gear is located between the two second gears and meshes with both of the second gears. The third gear is rotatably connected to the mounting base. The driving member is used to drive one of the second gears to rotate.

[0011] By adopting the above technical solution and setting up a drive assembly, when the rotor needs to be cleaned, the rotor is hoisted onto the support wheels, and the long shaft of the rotor is supported and positioned by two support rollers on both sides of the frame. The drive component drives a second gear to rotate, and the second gear drives another second gear to rotate through a third gear, thereby driving the two support rollers to rotate, which in turn drives the rotor to rotate. The circumferential surface of the rotor is cleaned by the cleaning equipment, which can be achieved without manually rotating the rotor.

[0012] Optionally, the driving component includes a motor, a first gear, and a rack. The motor housing is directly or indirectly fixedly connected to the mounting base. The motor output shaft is rotatably connected to the side wall of the mounting base. The motor output shaft is parallel to a first direction. The first gear is coaxially sleeved on the motor output shaft.

[0013] The rack is parallel to a third direction and is slidably connected to the mounting base along the third direction. The rack meshes with the first gear, and one of the second gears meshes with the rack.

[0014] By adopting the above technical solution, the first gear is driven to rotate by the motor. The first gear drives the rack to slide in a third direction, which in turn drives the second gear to rotate. Furthermore, the third gear drives another second gear to rotate, thereby driving the two support rollers to rotate, thus realizing the rotation of the rotor.

[0015] Optionally, the mounting base is disposed on the frame, the support roller is rotatably connected to the mounting base, the support roller is located on the side of the mounting base away from the frame, one of the mounting bases is fixedly connected to the frame, the other mounting base is slidably connected to the frame along a first direction, and the drive assembly is disposed on the side of the mounting base fixedly connected to the frame.

[0016] By adopting the above technical solution, since the rotors have different length specifications, in order to support rotors of different lengths, the distance between the two support members can be adjusted by moving one mounting base along the first direction, so that the support rollers on both sides of the frame can support rotors of different lengths.

[0017] Optionally, a first slider is fixedly connected to one side of one of the mounting bases, and a first groove for sliding the first slider is provided on the frame along a first direction.

[0018] By adopting the above technical solution, in order to make the mounting base slide, a first slide groove is provided on the frame along the first direction for the first slider to slide. The first slider slides in the first slide groove along the first direction, thereby driving the two support rollers on one side of the frame to move.

[0019] Optionally, the mounting base is fixed to the frame by a fastener.

[0020] By adopting the above technical solution, when the mounting base slides along the first direction to the required position to support the rotor, it needs to be fixed. By setting a fixing component, the mounting base is fixed to the frame to ensure the stability when supporting the rotor.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This application, by setting up a drive assembly, allows the rotor to be hoisted onto support wheels when cleaning is required. Two support rollers on both sides of the frame support and position the rotor's long shaft. The drive unit drives a second gear to rotate, and the second gear drives another second gear to rotate through a third gear, thereby driving the two support rollers to rotate, which in turn drives the rotor to rotate. The circumferential surface of the rotor is then cleaned by the cleaning equipment, eliminating the need for manual rotation of the rotor.

[0023] This application adjusts the distance between two supports by setting one of the mounting bases to slide along a first direction, thereby accommodating rotors of different lengths. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a rotor circumferential surface cleaning carrier. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where X represents the first direction X, Y represents the second direction Y, and Z represents the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0031] Reference Figure 1 One end of the rotor is fixedly connected to a long shaft, and the other end is fixedly connected to a short shaft.

[0032] Reference Figure 1 A rotor circumferential surface cleaning carrier includes a frame 1 and a support assembly 2. The support assembly 2 is mounted on the frame 1 and includes two support members 21 spaced apart in a first direction. Each support member 21 includes two support rollers 211 spaced apart in a second direction. The support rollers 211 are connected to the frame 1 through a mounting base 22. There is a support gap 212 between the two support rollers 211 in the second direction. The support rollers 211 are rotatably connected to the mounting base 22 and are parallel to the first direction along the first rotation axis 36 of the mounting base 22. When the rotor needs to be cleaned, the rotor is hoisted onto the support rollers, and the long shaft of the rotor is supported by the two support members 21 on both sides of the frame 1.

[0033] Reference Figure 1 , Figure 2 and Figure 3 To facilitate cleaning of the rotor's circumferential surface, a support roller 211 is rotatably connected to the frame 1. To drive the support roller 211, the rotor circumferential surface cleaning carrier also includes a drive assembly 3 for driving the support roller 211. The drive assembly 3 is located on one side of a mounting base 22 and includes a drive component 31, a second gear 32, and a third gear 33. The drive component 31 includes a motor 311, a first gear 312, and a rack 313. The motor 311 housing is fixedly connected to the mounting base 22 via a fixing plate 34. The output shaft of the motor 311 is rotatably connected to the side wall of the mounting base 22. The output shaft of the motor 311 is parallel to a first direction, and the first gear 312 is coaxially sleeved on the output shaft of the motor 311. The rack 313 is parallel to a third direction. The fixing block 35 is connected to the mounting base 22. The fixing block 35 is fixedly connected to the mounting base 22. The fixing block 35 has a third sliding groove 351 through it along the third direction. One side of the rack 313 is located in the third sliding groove 351 and slides along the groove wall of the third sliding groove 351. In this embodiment, the third sliding groove is a T-shaped groove. The rack 313 meshes with the first gear 312. The two support rollers 211 of each support member 21 are rotatably connected to the mounting base 22 through the first rotating shaft 36. The first rotating shaft 36 is parallel to the first direction. The first rotating shaft 36 is directly or indirectly rotatably connected to the mounting base 22. The support rollers 211 are coaxially fixedly sleeved on the first rotating shaft 36. A second gear 32 is fixedly sleeved on the first rotating shaft 36. One of the second gears 32 meshes with the rack 313.

[0034] Reference Figure 2 and Figure 3 The third gear 33 is located between the two second gears 32. The third gear 33 is rotatably connected to the mounting base 22 via the second rotating shaft 37. Specifically, the second rotating shaft 37 is parallel to the first direction and is directly or indirectly rotatably connected to the mounting base 22. The second rotating shaft 37 is parallel to the third direction along the rotation axis of the mounting base 22. The third gear 33 is coaxially sleeved on the second rotating shaft 37 and meshes with the two second gears 32. The motor 311 drives the first gear 312 to rotate. The first gear 312 drives the rack 313 to slide along the third direction, driving the second gear 32 to rotate. Furthermore, the third gear 33 drives the other second gear 32 to rotate, thereby driving the two support rollers 211 to rotate, realizing the rotation of the rotor.

[0035] Reference Figure 4Since the rotors have different length specifications, in order to support rotors of different lengths, the mounting base 22 is provided on the frame 1, and the support roller 211 is rotatably connected to the mounting base 22. The support roller 211 is located on the side of the mounting base 22 away from the frame 1. One mounting base 22 is fixedly connected to the frame 1, and the other mounting base 22 is slidably connected to the frame 1 along the first direction. The drive assembly 3 is provided on the side of the mounting base 22 fixedly connected to the frame 1. When it is necessary to support rotors of different lengths, the distance between the two support members 21 can be adjusted by simply moving one mounting base 22 along the first direction.

[0036] Reference Figure 4 In order to drive the mounting base 22 to slide, a first slider 221 is fixedly connected to one side of one of the mounting bases 22. A first groove 11 for the first slider 221 to slide is provided on the frame 1 along the first direction. In this embodiment, two first grooves 11 are spaced apart along the second direction. The first slider 221 slides in the first groove 11 along the first direction, thereby driving the two support rollers 211 on one side of the frame 1 to move.

[0037] Reference Figure 4 When the mounting base 22 slides along the first direction to the required position to support the rotor, it needs to be fixed. For this purpose, the mounting base 22 is fixed to the frame 1 by the fixing member 4. In this embodiment, the fixing member 4 is a bolt, so that the mounting base 22 is fixed to the frame 1 by the fixing member 4 to ensure the stability when supporting the rotor.

[0038] The implementation principle of a rotor circumferential surface cleaning carrier according to an embodiment of this application is as follows: In use, according to the size of the rotor, one of the mounting seats 22 is slid along the first direction to the desired position, and the mounting seat 22 is fixed to the frame 1 with the fixing member 4. The rotor is suspended between two support rollers 211. The long axis of the rotor is supported by two support rollers 211 on one side of the frame 1, and the short axis of the rotor is supported by two support rollers 211 on the other side of the frame 1. The drive motor 311 rotates, the motor 311 drives the first gear 312 to rotate, the first gear 312 drives the rack 313 to slide along the third direction, drives a second gear 32 to rotate, and further drives another second gear 32 to rotate through the third gear 33, thereby driving the two support rollers 211 to rotate, realizing the rotation of the rotor, so as to facilitate the cleaning of the rotor circumferential surface by the cleaning equipment.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
