Description

Technical Field

[0001] The utility model relates to the field of go / no-go gauges, in particular to an adjustable go / no-go gauge. Background Art

[0002] If the lithium battery in the energy storage box is hit and falls to the ground or hits other objects, it may cause an internal short circuit in the battery. If not handled in time, it can easily lead to a serious accident. The lithium battery is installed in the battery rack of the energy storage box, so the installation requirements and installation clearance requirements of the battery rack are very strict during installation. During the production process, the position and clearance of the battery rack are usually checked using a go / no-go gauge. This step is very important for subsequent processes. However, due to the different clearance requirements required by different product designers, it is necessary to frequently process and replace the corresponding go / no-go gauges, resulting in a waste of manpower and material resources.

[0005] Preferably, the top end of the first component includes a first table surface and a second table surface, the radius and area of the first table surface are equal to those of the second table surface, and the first table surface is higher than the second table surface, that is, the first table surface is a stop gauge and the second table surface is a through gauge; when the product to be tested is qualified, the second table surface can enter the product to be tested, while the first table surface cannot enter.

[0006] Preferably, the bottom end of the first component has an external thread, and the center of the second component is provided with a threaded hole to achieve threaded connection.

[0007] Preferably, the first component includes a connecting component and a functional component, the connecting component, the functional component and the second component are all cylindrical structures, the connecting component is coaxial with the functional component and the end faces are connected, the diameter of the functional component is equal to the diameter of the second component and is larger than the diameter of the connecting component; the connecting component has an external thread and is threadedly connected to the second component, and the functional component has the first table surface and the second table surface.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. In order to solve the problem that the existing go / no-go gauge cannot be adjusted, the utility model improves the go / no-go gauge into two parts, which are connected by a thread in the middle. The detection size can be adjusted by the thread structure, which can adapt to different models of products. There is no need to redraw or make the gauge after changing the product, saving manpower and material resources.

[0010] 2. The utility model can be adjusted to the required size by directly rotating, which is easy to operate and saves work effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural diagram of the utility model;

[0012] Figure 2 This is an embodiment of the present utility model. DETAILED DESCRIPTION

[0013] See also Figure 1 The utility model discloses an adjustable go / no-go gauge, comprising a first component 1 and a second component 2. The first component 1 comprises a connecting component 12 and a functional component 11. The connecting component 12, the functional component 11, and the second component 2 are all cylindrical structures. The connecting component 12 and the functional component 11 are coaxial and connected to each other at their end faces. Therefore, the top end of the first component 1 is the top end of the functional component 11, and the bottom end of the first component 1 is the bottom end of the connecting component 12.

[0014] The top of the functional component 11 includes a first table 11a and a second table 11b. The radius and area of the first table 11a are equal to those of the second table 11b, and the first table 11a is higher than the second table 11b. That is, the distance from the second table 11b to the bottom of the second component 2 is shorter than the distance from the first table 11a to the bottom of the second component 2. In other words, the first table 11a is a stop gauge and the second table 11b is a through gauge. The distance between the first table 11a and the second table 11b is determined according to the requirements of actual testing.

[0015] The bottom end of the connecting member 12 has an external thread, and a threaded hole is opened in the center of the second member 2. The first member 1 and the second member 2 are connected through the threaded structure, and the first table 11a, the second table 11b and the two end faces of the second member 2 are parallel.

[0016] The first component 1 and the second component 2 are rotated relative to each other through the threaded structure, thereby adjusting the distance from the top end face of the first component 1 to the bottom end face of the second component 2, that is, the height of the entire go / no-go gauge, that is, the required detection size of the product to be tested.

[0017] To facilitate the connection and locking of the first and second components 1 and 2, the diameter of the functional component 11 is equal to that of the second component 2 and larger than that of the connecting component 12. Therefore, after determining the required inspection dimensions of the product to be tested, the first and second components 1 and 2 can be locked together using the fine-thread nut 3. The fine-thread nut 3 is located on the smaller-diameter connecting component 12 and does not protrude from the entire gauge, making the entire gauge more complete.

[0018] After adjusting the length according to the needs of different manufacturers and locking the inspection fixture, the bottom end of the second component 2 is brought into contact with one side of the product to be tested. If the product to be tested is qualified, the lower second table 11b can enter the product to be tested, while the higher first table 11a cannot enter.

[0019] The utility model takes the detection of the position gap of the battery rack as an example and provides the following Figure 2 In the embodiment shown, the diameter of the functional component 11 and the second component 2 is 50 mm, the distance between the first table 11a and the second table 11b is 2±0.1 mm, and the first component 1 and the second component 2 are rotated relative to each other so that the distance from the first table 11a to the bottom end face of the second component 2 is 73.74 mm.

[0020] The battery rack includes a battery bracket and a guide plate. The guide plate and the battery bracket are parallel. The bottom end face of the second component 2 is in direct contact with the side of the battery bracket facing the guide plate. The top end of the first component 1 is used to detect whether the distance from the guide plate to the battery bracket is qualified.

[0021] If the second table 11b enters between the two and the first table 11a fails to enter between the two, the distance is qualified; if both the first table 11a and the second table 11b enter between the two, the distance is too large; if neither the first table 11a nor the second table 11b enters between the two, the distance is too small.

[0022] In summary, the utility model can adjust the detection size through the threaded structure, can adapt to different models of products, and does not need to remake the inspection fixture after the product is changed, saving workers from repeatedly drawing and processing. The utility model can be adjusted to the required size by directly rotating, which is easy to operate and saves work.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
