Technical Field

[0001] This utility model relates to the field of electric motor manufacturing and processing technology, and in particular to a casing cleaning device. Background Technology

[0002] During the manufacturing and processing of electric motors, if there is oil or debris on the surface of the housing, assembly stress may be generated during assembly due to forced pressing or hammering. These stresses may cause deformation, wear, or even damage to parts during motor operation, affecting the stability and reliability of the motor.

[0003] Patent document CN110773516B discloses a self-adaptive electromechanical equipment housing cleaning device, including a base plate. Lower support frames are vertically mounted at both ends of the top of the base plate. A control box is mounted on the outer side of one of the lower support frames. Clamping mechanisms are symmetrically arranged on the sides of the two lower support frames that are close to each other. Upper support frames are vertically connected to the top of each lower support frame. A driving mechanism and a cleaning mechanism are respectively provided between the two upper support frames. This invention, by setting up clamping mechanisms, can fix and clamp the electromechanical equipment housing, thereby effectively improving the stability during the cleaning process. The driving mechanism can drive the cleaning mechanism, facilitating repeated cleaning of the electromechanical equipment housing. Simultaneously, it drives the clamping mechanisms to rotate, thereby facilitating the cleaning device's cleaning of the electromechanical equipment housing.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: the inside of the motor housing is used to house parts, such as bearings and rotors, while the outside is used for isolation and protection; therefore, both the inner and outer layers need to be cleaned. Furthermore, to maintain the stability of the housing during cleaning, it needs to be fixed, but the components used to fix the housing inevitably obstruct parts of the inner and outer layers, requiring multiple adjustments to the fixing position to achieve comprehensive cleaning. Therefore, a housing cleaning device is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a shell cleaning device to address the above-mentioned technical problems, thereby solving the technical problems of inconvenience in cleaning the inner and outer layers simultaneously, and the inability to clean parts of the shell due to its fixed nature.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A housing cleaning device includes a base and further includes: The cleaning mechanism consists of a frame, and an inner cleaning section and an outer cleaning section connected to the frame and capable of contacting the inner and outer layers of the housing. A linear module, mounted on the base and capable of moving the frame along the length of the base, so that the inner and outer cleaning portions move to cover at least a portion of the inner and outer layers of the housing; and The support mechanism includes a first base and a bushing that is retractable on the first base and can be at least partially fitted onto the outer shell, the bushing being able to shorten its length on the outer shell by the action of the inner cleaning part.

[0007] As a preferred embodiment of the shell cleaning device provided by this utility model, the inner cleaning part includes a disc body, a braking component capable of driving the disc body to rotate, and a second contact ring detachably connected to the disc body, wherein the second contact ring is adapted to the inner diameter of the shell. The frame includes a second base that is partially sleeved and fixed to the brake component, and a set of support arms that are fixed to the second base in opposite directions. The end of the set of support arms that is away from the end fixed to the second base extends toward the disc body. The external cleaning unit includes an outer frame detachably connected between one end of a set of support arms, and a first contact ring detachably connected to the outer frame and capable of being fitted onto the outside of the housing.

[0008] As a preferred embodiment of the shell cleaning device provided by this utility model, it further includes a connecting frame, which is connected between the linear module and a set of support arms.

[0009] In a preferred embodiment of the housing cleaning device provided by this utility model, the linear module includes a base plate, a transmission part and a set of guide parts connected to one side of the base plate, and a slide fixed to the connecting frame and drivenly connected to the transmission part to be able to move linearly between the set of guide parts.

[0010] As a preferred embodiment of the shell cleaning device provided by this utility model, the first base is provided with a through hole that can accommodate the bushing, and the bushing is non-rotatable from the through hole by a set of limiting structures. The bushing is provided with a rotation-resisting structure to limit the rotation of the outer shell.

[0011] In a preferred embodiment of the housing cleaning device provided by this utility model, a set of limiting structures each includes a groove recessed into the bushing to form a groove, and a protrusion fixed to the through hole and extending into the groove.

[0012] In a preferred embodiment of the shell cleaning device provided by this utility model, the diameter of the through hole is larger than the diameter of the bushing, so that when the bushing passes through the limiting structure in the through hole, the through hole does not contact the anti-rotation structure. The anti-rotation structure consists of multiple sets of protrusions equidistantly arranged along the length of the bushing, and each set of protrusions consists of circumferentially equidistant protrusions outside the bushing. The bushing is equipped with a handle.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects: The present invention provides a shell cleaning device that, through the coordinated operation of the cleaning mechanism and the linear module, can simultaneously clean the inner and outer layers of the shell, thereby removing stains from the inner and outer layers, and improving the working efficiency of shell cleaning compared to cleaning the inner and outer layers of the shell separately. The present invention provides a shell cleaning device, which, through a supporting mechanism, can gradually detach from the shell as the cleaning mechanism advances the shell cleaning process. During the detachment process, the inner cleaning part of the cleaning mechanism plays a connecting role to the shell, thereby maintaining the stability of the shell and enabling a comprehensive cleaning of the shell.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figure 1 As shown, this type of shell cleaning device includes a base 1, a cleaning mechanism 2, a linear module 3, and a supporting mechanism 4. One side of the base 1 extends vertically upward to form a support portion. The cleaning mechanism 2 is connected to the support portion through the linear module 3, so that the cleaning mechanism 2 is vertically suspended on the base 1. The cleaning mechanism 2 connected to the linear module 3 is used to clean the shell, specifically to clean the inner and outer layers of the shell (see below for details). The linear module 3 is used to drive the cleaning mechanism 2 to move linearly and completely through the shell, thereby cleaning the shell thoroughly. The support mechanism 4 is connected to the base 1 and is positioned relative to the cleaning mechanism 2. The support mechanism 4 is used to connect the housing by means of a sleeve. The connected housing can move onto the support mechanism 4 as the cleaning mechanism 2 progresses, thus reducing the length of the housing sleeved on the support mechanism 4. During this process, a portion of the cleaning mechanism 2 enters the housing to continue to support and connect the housing in conjunction with the support mechanism 4. In other words, for example, when a portion of the cleaning mechanism 2 moves from one end of the housing to the other, the length of the connection between the support mechanism 4 and the housing gradually shortens until the portion of the cleaning mechanism 2 pushes the housing away from the support mechanism 4. At this point, the housing is completely cleaned by the cleaning mechanism 2 and automatically detaches from the support mechanism 4, thus eliminating the need to remove the housing from the support mechanism 4.

[0023] like Figure 2 As shown, and for reference Figure 1 The cleaning mechanism 2 further consists of a frame 21, an inner cleaning section 22, and an outer cleaning section 23. Specifically, the inner cleaning section 22 and the outer cleaning section 23 are both connected to the frame 21. Under the drive of the linear module 3, the inner cleaning section 22 enters the housing, and the outer cleaning section 23 covers the outside of the housing, so that the inner and outer layers of the housing can be cleaned simultaneously when moving.

[0024] like Figure 3 As shown, and for reference Figure 2 The internal cleaning part 22 includes a disc body 221, a brake element 222, and a second contact ring 232. Specifically, the brake element 222 is preferably a reduction motor. The disc body 221 is coaxially connected to the motor, so the disc body 221 rotates under the drive of the motor. The second contact ring 232 is sleeved on the disc body 221, and a screw is driven from the inside of the disc body 221 to the root of the second contact ring 232 to fix the second contact ring 232 to the disc body 221. The second contact ring 232 is a sponge or wiping cloth with a certain thickness, and the second contact ring 232 is adapted to the inner diameter of the outer shell. However, when the second contact ring 232 is worn and cannot fully contact the inner surface of the shell, it can be removed and replaced by removing the screws. The external cleaning section 23 includes an outer frame 231 and a first contact ring 223. Specifically, the first contact ring 223 is a wire brush and is integrally connected to the outer frame 231. The shape shown in the figure is only schematic. For example, when the shell is circular, the first contact ring 223 is circular. However, when the shell is provided with a base for connecting the control compartment and a bottom support, the first contact ring 223 is shaped like the edge of the shell's positive plane angle, thereby preventing the outer frame 231 from contacting the shell. When the wire brush contacts the shell, it bends to one side and enters the gap between the heat dissipation and / or reinforcing ribs arranged in the outer circumferential array of the shell to clean the dirt in the gap. The frame 21 further includes a second base 211 and a set of support arms 212. Specifically, the second base 211 is partially sleeved with and fixed to the brake 222, and is integrated with the brake 222. One end of each set of support arms 212 is fixed to the second base 211 in the vertical direction, and the other end extends towards the first contact ring 223. At the same time, it is detachably connected to the outer frame 231, that is, by inserting bolts into the support arms 212 and the outer frame 231, the outer frame 231 is fixed between the set of support arms 212. When the wear is severe, the bolts can be removed to replace it.

[0025] like Figure 4 As shown, and for reference Figure 2 and Figure 3 A fixed connecting frame 5 is fixed between the linear module 3 and a set of support arms 212, so that the linear module 3 drives the set of support arms 212 to move through the connecting frame 5. Since the inner cleaning part 22 and the outer cleaning part 23 are both connected to the set of support arms 212, they enter and cover the inner and outer surfaces of the housing under the drive of the set of support arms 212. In some embodiments, as shown in the figure, the linear module 3 further includes a base plate 31, a transmission part 32, a set of guide parts 33, and a slide block 34. Specifically, the base plate 31 is fixedly connected to the support part of the base 1, the transmission part 32 is a combination of a ball screw and a stepper or servo motor, the guide part 33 is composed of a guide rail and a slider, and the slide block 34 is connected to the screw drive by fixing a ball nut. At the same time, the slide block 34 is also fixed to the connecting frame 5, so that when the screw rotates, the slide block 34 moves linearly on the guide rail by the slider, and drives a set of support arms 212 to move through the connecting frame 5.

[0026] like Figure 5 As shown, the bearing mechanism 4 further includes a first base 41 and a bushing 42. Specifically, the first base 41 has a through hole, and the bushing 42 is non-rotatably moved away from the through hole by a set of limiting structures 43. The length of the bushing 42 outside the first base 41 (i.e., the direction adjacent to the cleaning mechanism 2) is adjusted by the limiting structures 43 so that the shell is sleeved on the bushing 42. Since the bushing 42 is provided with a rotation-blocking structure 44, the rotation-blocking structure 44 can be squeezed and contracted when the shell is sleeved, so that the shell can move laterally and linearly on the bushing 42. However, when the shell rotates on the bushing 42, the rotation-blocking structure 44 will not be subjected to rotational force and will contract, thereby preventing the shell from rotating on the bushing 42. This prevents the shell from rotating on the bushing 42 under the rotation of the inner cleaning part 22, so that the shell remains non-rotatable and receives the cleaning of the inner cleaning part 22's rotation and linear movement. Each set of limiting structures 43 further includes a groove 431 formed by recessing into the bushing 42, and a protrusion 432 fixed to the through hole and extending into the groove 431. Specifically, the protrusion 432 can only move linearly in the groove 431, thereby restricting the bushing 42 from rotating in the through hole.

[0027] like Figure 6 As shown, and for reference Figure 5 The diameter of the through hole is larger than the diameter of the bushing 42, so that when the bushing 42 moves through the through hole under the push of the cleaning progress of the inner cleaning part 22, the through hole does not contact the anti-rotation structure 44; and the bushing 42 moves through the through hole to reduce the length of the bushing 42 connected to the housing. During the process, one end of the housing will abut against the first base 41, and combined with the small part of the anti-rotation structure 44 that is not exposed by the bushing 42, so as to continue to restrict the housing from rotating under the drive of the inner cleaning part 22. The anti-rotation structure 44 is further composed of multiple sets of protrusions equidistantly arranged along the length of the bushing 42. Each set of protrusions is composed of protrusions 441 equidistant from the outside of the bushing 42. Specifically, as shown in the enlarged part in the figure, the protrusions 441 are arc-shaped blocks with a "D" shape at least one-fifth of the circumference at the top. Since the lowest points at both ends of the protrusions 441 are arranged in the length direction of the bushing 42, when the housing is fitted, the inner surface of the housing will only contact the highest point of the protrusions 441 in a line contact manner. When the housing moves linearly on the bushing 42, the protrusions 441 will slightly contract, and the rounded design from the highest point to the lowest point will reduce the moving friction with the housing, so that the housing can move on the bushing 42 under the push of the inner cleaning part 22. When the housing wants to rotate on the bushing 42, the two ends of the protrusion 441 in the length direction are neatly cut, making it difficult to shrink, thus preventing the housing from rotating on the bushing 42; the bushing 42 is also provided with a handle 45, and the position of the bushing 42 on the first base 41 can be adjusted by the handle 45.
