[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0033] It should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0034] It should be understood that the terms "system," "apparatus," "unit," and / or "module" used in this application are a method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0035] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "a," and / or "the" are not specifically singular and may include the plural. Generally, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements. An element defined by the phrase "comprising an..." does not exclude the presence of other identical elements in the process, method, product, or apparatus that includes the element.

[0036] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] Flatness is the maximum permissible deviation of the actual surface being measured relative to an ideal plane. The ideal plane is the reference plane, and the maximum distance from each point on the actual surface to the ideal plane is the flatness value.

[0039] The motor cooler tube sheet needs to fit tightly against the cooler housing to ensure a seal. If the flatness of the sealing surface of the motor cooler tube sheet is not up to standard (for example, if there are depressions or protrusions on the surface of the motor cooler tube sheet), it will lead to water leakage problems.

[0040] Please see Figure 1This is a schematic diagram of the flatness adjustment device disclosed in this solution. The flatness adjustment device includes a grinder 1 and a handle 2. The grinder 1 is used to grind the workpiece, and the handle 2 is used for the user to grip. Slowly and evenly pushing the handle 2 will drive the grinder 1 to grind the workpiece.

[0041] This solution uses a motor cooler tube sheet as an example to illustrate the solution. The flatness adjustment device disclosed in this solution is not limited to motor cooler tube sheets.

[0042] When in use, the user grips handle 2 and drives grinder 1 to grind the sealing surface of the motor cooler tube plate to ensure that the flatness of the sealing surface of the motor cooler tube plate meets the requirements, thus solving the water leakage problem caused by unqualified flatness.

[0043] The handle 2 includes a connecting section 21 and a telescopic section 22. Connecting sections 21 are provided at both ends of the telescopic section 22 in the telescopic direction. One end of each connecting section 21 is connected to the telescopic section 22, and the other end is connected to the grinder 1. Optionally, the two connecting sections 21 are located on the same side of the telescopic section 22 in the telescopic direction. The user holds the telescopic section 22 to operate the flatness adjustment device to grind the sealing surface of the motor cooler tube sheet.

[0044] The telescopic section 22 is a telescopic structure, and it is straight. The telescopic direction of the telescopic section 22 is consistent with its own length extension direction. The telescopic section 22's extension and contraction adjust the distance between the connecting sections 21 at both ends. Specifically, when the telescopic section 22 extends, its overall length increases, increasing the distance between the two connecting sections 21 at both ends, thus increasing the distance between the two grinders 1. When the telescopic section 22 shortens, its overall length decreases, decreasing the distance between the two connecting sections 21 at both ends, thus decreasing the distance between the two grinders 1. This allows the flatness adjustment device to adapt to motor cooler tube sheets of different specifications. The flatness adjustment device disclosed in this solution has strong versatility.

[0045] There are two connecting segments 21, and correspondingly, there are also two grinders 1.

[0046] In this design, the grinder 1 is symmetrically distributed at both ends of the handle 2, which meets the needs of special scenarios such as symmetrical grinding.

[0047] Please see Figure 1 The two grinders 1 located at both ends of the telescopic section 22 in the telescopic direction have their own grinding surfaces. During operation, the two grinders 1 simultaneously grind two opposite positions on the motor cooler tube plate, which improves grinding efficiency and shortens grinding time to a certain extent.

[0048] When in use, press the handle 2. The force applied by the handle 2 to the two polishers 1 is similar, and the polishing effect of the two polishers 1 on the polishing area is also similar.

[0049] Continue reading Figure 2 The handle 2, which is composed of the telescopic section 22 and the connecting section 21, is U-shaped. The open end of the U-shaped handle 2 faces the motor cooler tube plate, and the user holds the closed end of the handle 2 to operate it.

[0050] Taking a rectangular motor cooling tube plate as an example, when the flatness adjustment device grinds the two long sides of the sealing surface of the motor cooling tube plate, the length of the telescopic section 22 is adjusted so that the two grinders 1 are directly opposite the long sides of the motor cooling tube plate, and the distance between the two grinders 1 is the width of the sealing surface of the motor cooling tube plate. The flatness adjustment device grinds the two long sides of the motor cooling tube plate simultaneously. When the flatness adjustment device grinds the two wide sides of the motor cooling tube plate, the length of the telescopic section 22 is adjusted so that the two grinders 1 are directly opposite the wide sides of the motor cooling tube plate, and the distance between the two grinders 1 is the length of the sealing surface of the motor cooling tube plate. The flatness adjustment device grinds the two wide sides of the motor cooling tube plate simultaneously.

[0051] The flatness adjustment device disclosed in this solution can be used to simultaneously grind two locations to be ground at different distances.

[0052] The telescopic section 22 includes a first section 221, a second section 222 and a locking member. The length extension direction of the first section 221 is consistent with the length extension direction of the second section 222, and the length extension direction of the first section 221 and the second section 222 is consistent with the telescopic direction. The first section 221 and the second section 222 are locked together by the locking member.

[0053] The first segment 221 and the second segment 222 move toward or away from each other in the telescopic direction to adjust the length of the telescopic segment 22. Specifically, when the first segment 221 and the second segment 222 move toward each other, the length of the telescopic segment 22 shortens; when the first segment 221 and the second segment 222 move away from each other, the length of the telescopic segment 22 lengthens.

[0054] After the positions of the first segment 221 and the second segment 222 are adjusted, the locking parts are tightened, and the length of the telescopic segment 22 is fixed.

[0055] The telescopic section 22 and the connecting section 21 can be plate-like structures or rod-like structures. The first section 221 and the second section 222 of the telescopic section 22 can also be plate-like structures or rod-like structures.

[0056] In an embodiment where the telescopic section 22 is a plate-like structure, the first section 221 and the second section 222 of the telescopic section 22 are strip plates of a certain length. The first section 221 and the second section 222 are stacked and arranged in a stacked manner. The stacking arrangement can be arranged in a vertical direction or in a horizontal direction.

[0057] In this embodiment, the first segment 221 includes a first adjustment hole, and the second segment 222 includes at least two second adjustment holes. By cooperating with the first adjustment hole of the first segment 221 and the second adjustment holes at different positions of the second segment 222, the length of the telescopic segment 22 composed of the first segment 221 and the second segment 222 can be adjusted.

[0058] After adjustment, the locking member extends into the first adjustment hole and the second adjustment hole that corresponds to and is connected to the first adjustment hole, locking the first section 221 and the second section 222, and fixing the length of the telescopic section 22.

[0059] In an embodiment where the telescopic segment 22 is a rod-shaped structure, the first segment 221 and the second segment 222 of the telescopic segment 22 are rod-shaped structures with a certain length, and the cross-section of the rod-shaped structure along the direction perpendicular to its own axis can be circular, rectangular or other polygonal.

[0060] In this embodiment, the overlapping position of the first segment 221 and the second segment 222 can be a plane, with the planes of the first segment 221 and the second segment 222 fitting together. The stacking arrangement can be arranged vertically or horizontally. The first segment 221 includes a first adjustment hole, and the second segment 222 includes at least two second adjustment holes. By cooperating with the first adjustment hole of the first segment 221 and the second adjustment holes at different positions of the second segment 222, the length of the telescopic segment 22 composed of the first segment 221 and the second segment 222 can be adjusted.

[0061] After adjustment, the locking member extends into the first adjustment hole and the second adjustment hole that corresponds to and is connected to the first adjustment hole, locking the first section 221 and the second section 222, and fixing the length of the telescopic section 22.

[0062] In this embodiment, the overlapping position of the first segment 221 and the second segment 222 can also be a guide hole and a guide rod. Specifically, the first segment 221 includes a guide hole, and the second segment 222 includes a guide rod. Both the guide hole and the guide rod are opened along the telescopic direction. The guide rod slides within the guide hole to achieve length adjustment of the telescopic segment 22. Specifically, when the guide rod slides into the guide hole, the length of the telescopic segment 22 shortens; when the guide rod slides out of the guide hole, the length of the telescopic segment 22 lengthens.

[0063] The guide hole has a locking hole on its wall. The locking element extends through the locking hole and abuts against the locking rod to lock the position of the locking rod. The length of the telescopic section 22 is fixed.

[0064] To ensure the tightness of the first section 221 and the second section 222 after they are fitted together, the extension section 22 can be tied to the outside of the extension section 22 with straps after the length of the extension section 22 is adjusted; the straps can also enhance the comfort of using the handle 2.

[0065] The connecting section 21 includes a horizontal section connected to the telescopic section 22 and a vertical section connected to the horizontal section. The vertical section is connected to the grinder 1.

[0066] The connecting section 21 may also consist only of a vertical section connected to the telescopic section 22, with one end of the vertical section connected to the telescopic section 22 and the other end of the vertical section connected to the grinder 1.

[0067] The connection between the connecting section 21 and the telescopic section 22 can be either a non-detachable connection or a detachable connection.

[0068] In embodiments where the connecting segment 21 and the telescopic segment 22 are connected in a non-detachable manner, the connecting segment 21 and the telescopic segment 22 may be welded, integrally formed, riveted, or other methods that can achieve a non-detachable connection between the connecting segment 21 and the telescopic segment 22, all of which are within the scope of protection of this application.

[0069] In embodiments where the connecting section 21 and the telescopic section 22 are detachably connected, the connecting section 21 and the telescopic section 22 can be connected by bolts, by binding, by snap-fit, or by other means that can achieve a detachable connection between the connecting section 21 and the telescopic section 22, all of which are within the scope of protection of this application.

[0070] The vertical and horizontal sections of the connecting segment 21 can be connected by welding, integral molding, or riveting.

[0071] The grinder 1 includes a mounting plate and sandpaper.

[0072] The mounting plate includes an upper surface and a lower surface. The upper and lower surfaces of the mounting plate are referenced in the vertical direction, with the upper surface located above the lower surface.

[0073] The upper surface of the mounting plate is connected to the connecting section 21, and sandpaper is installed on the lower surface of the mounting plate.

[0074] In some embodiments, the mounting plate is glued to the sandpaper.

[0075] In other embodiments, the lower surface of the mounting plate is provided with oppositely arranged slots, into which the two sides of the sandpaper are inserted to fix the sandpaper on the mounting plate.

[0076] In other embodiments, the upper surface of the mounting plate is provided with a buckle, and the sandpaper is folded up from the edge of the mounting plate and engages with the buckle to fix the sandpaper on the mounting plate.

[0077] The connection method between the sandpaper and the mounting plate is not limited to the above embodiments. Other methods that can make the sandpaper flat and fixed on the mounting plate are also within the scope of protection of this application.

[0078] The connection between the mounting plate and the connecting section 21 can be achieved by welding, bolting, or riveting.

[0079] The grinder 1 is not limited to setting sandpaper under the mounting plate; a sandpaper-like grinding surface can also be set directly on the lower surface of the mounting plate, and the workpiece to be ground can be ground through the grinding surface of the mounting plate.

[0080] Optionally, the mounting plate is a long strip, the length of which is perpendicular to the telescopic direction of the telescopic section 22, and includes at least two handles 2 along its length. The user can select two handles 2 in appropriate positions according to their needs. Each of the user's hands acts on one handle 2, and both hands can apply force to the plane adjustment device simultaneously to facilitate force application and improve the polishing effect.

[0081] The flatness adjustment device disclosed in this solution is suitable for grinding surfaces where the two grinders 1 are at the same height and the two grinders 1 are in contact with the two grinding surfaces at the same time. When grinding two surfaces with different heights, the two grinders 1 can be made to be in contact with the two grinding surfaces by replacing the connecting section 21 with a different height or the mounting plate with a different thickness.
