[0023] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0025] Please refer to Figure 2 and Figure 3 The embodiment of the utility model provides a motor gauge 100, which includes a detection piece 11, and the detection piece 11 includes a main body 111 and an end 112 connected to each other; wherein the number of the end 112 is multiple, and there are at least two ends 112 with different widths, and the multiple ends 112 are all used for detecting distance.

[0026] It is worth noting that the motor inspection fixture 100 can select the end 112 that matches the position to be inspected by comparison through the provision of multiple ends 112 of different widths, thereby obtaining the size of the creepage distance of the position to be inspected. It has high detection adaptability, saves time and effort, and can improve production efficiency.

[0027] like Figure 2 As shown, there are multiple detection pieces 11 , and any detection piece 11 has multiple ends 112 .

[0028] It is worth noting that, since there are multiple detection sheets 11 and each detection sheet 11 has multiple ends 112, the design enhances the flexibility of the detection tool, can adapt to motors or electrical equipment of various shapes and sizes, can be used for a variety of detection needs, and improves detection efficiency and diversity. In addition, by setting that any detection sheet 11 has multiple ends 112, it can provide more detection points, thereby improving the accuracy and reliability of the detection.

[0029] like Figure 3 As shown, any detection piece 11 includes a main body 111 and two end portions 112 . The main body 111 is a rectangular strip structure, and the two end portions 112 are respectively disposed at two ends of the main body 111 .

[0030] It is worth noting that the main body 111 of the detection piece 11 is in the shape of a rectangular strip, and this structure can provide sufficient stability and support to ensure the accuracy and stability of the detection. The two ends 112 of each detection piece 11 are respectively located at the two ends of the main body 111, which enables the detection piece 11 to perform effective creepage distance detection at different positions and angles, thereby enhancing its applicability and flexibility. At the same time, the ends 112 on both sides can reduce the occurrence of mutual interference, so that the motor inspection fixture 100 can accurately measure the size of a position with a smaller space.

[0031] In this embodiment, the difference between the widths of the two ends 112 of any detection piece 11 is the same.

[0032] It is worth noting that this setting method allows the inspector to more conveniently find an end 112 that matches the position to be inspected, which is more in line with the inspection habits and is conducive to improving the inspection efficiency. Specifically, if the difference between the widths of the two ends 112 of the inspection sheet 11 is different, the widths of the ends of each inspection sheet are relatively messy, and it is difficult for the inspector to find the end that matches the position to be inspected in a certain pattern.

[0033] Please refer again Figure 2 The motor gauge 100 further includes a rotating shaft 12 , which is sequentially passed through the plurality of main bodies 111 , and the plurality of main bodies 111 can rotate around the axis direction of the rotating shaft 12 .

[0034] In this embodiment, the shapes of the plurality of main bodies 111 are the same, and the rotation shafts 12 are sequentially disposed through the center positions of the plurality of main bodies 111 .

[0035] It is worth noting that the multiple main bodies 111 can rotate around the rotating shaft 12, so the multiple main bodies 111 can be stored overlapping each other, which can reduce the overall size of the motor inspection fixture 100 to a minimum, thereby saving storage and carrying space. At the same time, when the main bodies 111 are stored overlapping each other, it is easier to keep the tools organized and avoid messy stacking of tools, thereby improving work efficiency. In addition, the detection sheets 11 that can be stored overlapping each other are more adaptable when used for size detection in some narrow locations, and the size measurement is more accurate.

[0036] In this embodiment, the widths of the plurality of ends 112 are all different.

[0037] Optionally, the widths of the plurality of ends 112 are in an arithmetic progression.

[0038] Specifically, the characteristics of the arithmetic progression make the width of the end 112 arranged regularly, simplifying the design and manufacturing process and improving the manufacturing efficiency. At the same time, the arithmetic progression of the width of the end 112 makes it easier for the inspector to understand and operate the motor inspection fixture 100. Its stepped regularity makes it easier to select the end 112 that matches the position to be inspected, thereby accurately obtaining the distance size of the position to be inspected.

[0039] In this embodiment, the tolerance between the widths of the multiple ends is 0.1 mm. It is understandable that a tolerance of 0.1 mm can make it easier for the inspector to match the end that cooperates with the position to be detected, and then measure the distance of the position to be detected. At the same time, a tolerance of 0.1 mm will not cause the problem of too small tolerance, thereby increasing the complexity of detection. Depending on the specific implementation environment, the widths of the multiple ends 112 can also be other sizes. This embodiment is only an example of some common detection sizes and does not constitute a limitation on their specific sizes.

[0040] Please refer again Figure 2 , the outer surface of the end 112 is provided with an identification body 113, and the identification body 113 is used to characterize the width of the end. It is understandable that the identification body 113 can be an identification protrusion or an identification groove. The present embodiment does not constitute a limitation on its specific structure. It is also worth noting that the identification body 113 corresponds to the width of the end 112, so that the inspector can easily identify and recognize the size and characteristics of each end 112, thereby improving the convenience and efficiency of use. At the same time, it can prevent the inspector from confusing the ends 112 of different widths during use, reduce errors and misunderstandings, and improve the accuracy of detection.

[0041] In summary, the present embodiment provides a motor gauge 100, which includes a detection piece 11, and the detection piece 11 includes a main body 111 and an end 112 that are connected to each other; wherein, the number of the end 112 is multiple, and there are at least two ends 112 with different widths, and the multiple ends 112 are all used to detect distance. The motor gauge 100 can select the end 112 that matches the position to be detected by comparison through the setting of multiple ends 112 of different widths, so as to obtain the size of the creepage distance of the position to be detected. It has high detection adaptability, saves time and effort, and can improve production efficiency.
