Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, and in particular to a thickness testing fixture. Background Technology
[0002] The thickness of a product may deviate due to factors such as manufacturing errors and improper assembly of components. In existing technologies, to check whether a product's thickness meets standards, operators typically measure it manually or visually, leading to low efficiency and even errors in judgment. Alternatively, precision testing fixtures may be used, but the complex internal structure of these fixtures can interfere with the product, scratching its outer casing and affecting its appearance.
[0003] Therefore, how to design a thickness measurement fixture that can ensure the accuracy of product thickness measurement while avoiding scratching the product during the measurement process has become a new research topic. Utility Model Content

[0009] The distance between the first detection surface and the second detection surface corresponds to the standard thickness of the side to be measured.

At this time, the sliding distance of the detection slider is between 4 / 5 and 9 / 10 of the length of the side to be measured. When the actual thickness of the first detection point of the side to be measured is greater than the standard thickness, the detection slider is blocked during the sliding process and stops at the first detection point.

[0014] More preferably, the first vertical bar and / or the second vertical bar are adjustablely disposed on the inclined surface;
[0015] The adjustment direction of the first vertical bar and / or the second vertical bar is perpendicular to its length extension direction, so as to adjust the spacing between the first vertical bar and the second vertical bar, so as to limit the test products with different thickness specifications.
[0016] More preferably, one of the first vertical bar and the inclined surface has a guide groove, the extension direction of which is parallel to the adjustment direction of the first vertical bar, and the other has a corresponding limiting block, which is slidably disposed in the guide groove;

[0031] To provide a better understanding of the purpose, structure, features and functions of this utility model, detailed descriptions are provided below with reference to the embodiments.
[0032] Certain terms are used in the specification and claims to refer to specific elements. It will be understood by those skilled in the art that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to".
[0033] An embodiment of this utility model provides a thickness detection fixture 1. Please refer to [link / reference]. Figures 1 to 2 These are schematic diagrams of the thickness measuring fixture 1 from different perspectives. The thickness measuring fixture 1 includes a base 11 and a measuring slider 12. The base 11 supports the product 2 to be measured. The measuring slider 12 includes a first measuring surface 12a, a second measuring surface 12b, and a connecting portion 12L. The first measuring surface 12a and the second measuring surface 12b are respectively arranged parallel to each other at opposite ends of the connecting portion 12L. The product 2 to be measured is, for example, a battery pack, a product with high requirements for the upper limit of thickness. It has multiple sides. When the product 2 to be measured is confined to the base 11, at least one of these sides is the side to be measured. The extension direction of this side to be measured is inclined relative to the vertical direction (the opposite direction of the z-direction) and does not contact the base 11. The measuring slider 12 is slidably placed on this side to be measured, and this side to be measured is located between the first measuring surface 12a and the second measuring surface 12b of the measuring slider 12. The structural schematic diagram of the measuring slider 12 is shown below. Figure 3A and Figure 3BAs shown, the distance D2 between the first detection surface 12a and the second detection surface 12b corresponds to the standard thickness of the side to be tested. In other words, the dimensions of the detection slider 12 are manufactured based on the standard thickness of the product 2 under test. When the actual thickness of the side to be tested is less than or equal to the standard thickness, the detection slider 12 can slide down along the side under test due to gravity. At this time, the sliding distance of the detection slider 12 is between 4 / 5 and 9 / 10 of the length of the side to be tested. That is, the length of the detection slider 12 is between 1 / 10 and 1 / 5 of the length of the side to be tested, and the entire sliding process of the detection slider 12 is from one end of the side to the opposite end. The detection slider 12 has a smaller size and is correspondingly lighter, making it less likely to scratch the outer shell of the product 2 under test. Preferably, as... Figure 1 As shown, the angle A between the extension direction of the side to be tested and the vertical direction is between 30° and 60° to ensure that the detection slider 12 can slide smoothly under the action of gravity. That is to say, only when the production error of the product under test 2 is within an acceptable range, and / or all components are assembled in place, can the thickness of each side of the product under test 2 be equal to or slightly less than the standard thickness. At this time, the side to be tested, which is inclined relative to the vertical direction, can assist the detection slider 12 placed on it to slide down under its own gravity. The surface of the detection slider 12 can also be smoothed to avoid excessive friction with the product under test 2, further protecting the shell of the product under test 2 from being scratched by the detection slider 12. If the detection slider 12 cannot slide down smoothly, it means that the thickness of the product under test 2 is too large (unqualified), and the position where the detection slider 12 is stuck is the position where the thickness of the product under test 2 is abnormal. For example, if the actual thickness of the first detection point on the side to be tested is greater than the standard thickness, the detection slider 12 will be blocked during its descent and stop at the first detection point. Technicians can then rework or repair the product 2 to be tested based on the location of the first detection point, thereby improving production efficiency.
[0034] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the product under test 2 is formed by the multiple side edges into a first surface and a second surface facing away from each other, i.e., two opposing surfaces in the x-direction. The actual thickness of the product under test is the distance between the first surface and the second surface. Further preferably, as... Figure 3A and Figure 3BAs shown, a first detection surface 12a and a second detection surface 12b are respectively disposed at opposite ends of the connecting portion 12L, such that the detection slider 12 is in the shape of, for example, U-shaped, π-shaped, or H-shaped, or other similar shapes. When the detection slider 12 is placed on the side to be tested, the first surface faces the first detection surface, and the second surface faces the second detection surface. Preferably, the detection slider 12 can also be made of a material with a lower hardness than the outer shell of the product to be tested 2 (e.g., cork, plastic, etc.) to better protect the product to be tested 2.
[0035] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the base 11 includes two triangular uprights 113 and inclined surfaces 111. The two triangular uprights 113 are arranged opposite each other, and the inclined surfaces 111 are respectively disposed on the corresponding hypotenuses of the two triangular uprights 113, such that the extension direction of the inclined surfaces 111 is inclined to the vertical direction. In some other embodiments, the base 11 may also include a triangular prism (not shown in the figure, but can also be understood as a triangular upright 113 with a relatively thick width) whose side edges are placed horizontally. The inclined surface 111 may be directly a side surface of the triangular prism, or it may be a flat plate disposed on the side surface of the triangular prism. This utility model is not limited to this. In this embodiment, the product to be tested 2 is confined to the inclined surface 111. Figure 1 and Figure 2 As shown, one of the other sides of the product under test 2, excluding the side to be tested, abuts against the inclined surface 111; in some other embodiments, a surface of the product under test 2 may abut against the inclined surface 111 (not shown in the figure), and the side to be tested extends from the edge of the inclined surface 111 so that the side to be tested is inclined in the vertical direction and does not contact the base 11, but the actual application is not limited to this.
[0036] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the base 11 also has a plurality of blocking strips 112 disposed on the inclined surface 111, which form a limiting space for limiting the product 2 to be tested. Preferably, as... Figure 2As shown, the plurality of blocking strips 112 include a first vertical strip 112a, a second vertical strip 112b, and a first horizontal strip 112c. The first vertical strip 112a and the second vertical strip 112b are arranged parallel to each other, and the extension directions of the first vertical strip 112a and the second vertical strip 112b are parallel to the extension direction of the inclined surface 111. The product to be tested 2 is sandwiched between the first vertical strip 112a and the second vertical strip 112b, and the side to be tested is parallel to the first vertical strip 112a and the second vertical strip 112b, that is, the thickness direction of the product to be tested 2 is parallel to the x-direction, and the first vertical strip 112a and the second vertical strip 112b are located on opposite sides of the product to be tested 2 in the x-direction. The first horizontal strip 112c is arranged below the first vertical strip 112a and the second vertical strip 112b to support the bottom of the product to be tested 2. In other words, in this embodiment, the side of the product under test 2 is sandwiched between the first vertical bar 112a and the second vertical bar 112b, and abuts against the inclined surface 111. In other embodiments, the inclined surface 111 may also be provided with a slot (not shown in the figure) corresponding to the side shape of the product under test 2, and the product under test 2 is fixed by inserting the side of the product under test 2 into the slot. This utility model is not limited to this.
[0037] In a preferred embodiment, the first vertical bar 112a and / or the second vertical bar 112b are adjustablely disposed on the inclined surface 111. The adjustment direction d of the first vertical bar 112a and / or the second vertical bar 112b is perpendicular to its length extension direction; in other words, as shown... Figure 2 As shown, the adjustment direction d is parallel to the x-direction to adjust the interval distance D1 between the first vertical bar 112a and the second vertical bar 112b, so as to limit the measurement of various products with different thicknesses. This allows the base 11 to be used to test various products with different thickness specifications, improving the versatility of the thickness measurement fixture 1. Preferably, as Figure 4 As shown, a guide groove c is provided on the inclined surface 111, and a corresponding limiting block s is provided on the second vertical bar 112b. The extending direction of the guide groove c is parallel to the adjustment direction d of the second vertical bar 112b (i.e., parallel to the x-direction), and the limiting block s is slidably disposed in the guide groove c. In some other embodiments, the inclined surface 111 may have a limiting block s, and the second vertical bar 112b may have a guide groove c (not shown in the figure); in still other embodiments, one of the first vertical bar 112a and the inclined surface 111 may have a guide groove c, and the other may have a corresponding limiting block (not shown in the figure); this utility model is not limited thereto. Figure 4As shown, the number of guide grooves c and limiting blocks s is at least two, so as to prevent the limiting blocks s from rotating relative to the guide grooves c, thereby restricting the first vertical bar 112a and / or the second vertical bar 112b to move only along the adjustment direction d; or, the limiting block s can also be a square column, by the side wall of the square column abutting against the inner wall of the guide groove c, to prevent the limiting block s from rotating relative to the guide groove c, but the actual application is not limited to this.
[0038] In a preferred embodiment, such as Figure 1 As shown, when the product under test 2 is confined to the base 11, at least two of the multiple sides are the sides to be tested, and these at least two sides extend in different directions inclined to the vertical. There are at least two detection sliders 12, respectively placed on the at least two sides to be tested for simultaneous testing, thereby improving the efficiency of thickness detection. It should be noted that the thickness of each side of the product under test 2 may be different, meaning that the specifications of the corresponding detection sliders 12 may be different. For example, the distance D2 between the first detection surface 12a and the second detection surface 12b of each detection slider 12 may be different or adjustable relative to the connecting part 12L. This can be designed as needed by those skilled in the art and will not be elaborated further. Preferably, the product under test 2 is quadrilateral. When the product under test 2 is confined to the base 11, the adjacent first side 2a and second side 2b of the four sides are the sides to be tested, and the adjacent third side 2c and fourth side 2d of the four sides are respectively confined within the limiting space formed by the first vertical bar 112a, the second vertical bar 112b, and the first horizontal bar 112c. For example, as Figure 1 and Figure 2 As shown, the third side 2c is sandwiched between the first vertical bar 112a and the second vertical bar 112b, and the first horizontal bar 112c supports the fourth side 2d. Based on this, after the product under test 2 rotates 180° vertically, the third side 2c and the fourth side 2d become the sides to be measured, while the first side 2a and the second side 2b are confined within this confining space. At this time, the detection slider 12 is also used to place on the third side 2c and the fourth side 2d, thus allowing the thickness of all sides of the product under test 2 to be measured. Other shapes of products under test are similar and will not be described further.
[0039] In summary, embodiments of this utility model provide a thickness detection fixture, including a base and a detection slider. The base is used to support the product to be tested, and the detection slider includes a connecting portion and a first detection surface and a second detection surface respectively disposed parallel to each other at opposite ends of the connecting portion. The product to be tested has multiple sides. When the product to be tested is confined to the base, at least one of the multiple sides is the side to be tested, and the extension direction of the side to be tested is inclined relative to the vertical direction and does not contact the base. The detection slider is used to slidably rest on the side to be tested, and the side to be tested is located between the first detection surface and the second detection surface. The distance between the first detection surface and the second detection surface corresponds to the standard thickness of the side to be measured. When the actual thickness of the side to be measured is less than or equal to the standard thickness, the detection slider slides down the side to be measured under its own weight. At this time, the sliding distance of the detection slider is between 4 / 5 and 9 / 10 of the length of the side to be measured. When the actual thickness of the first detection point of the side to be measured is greater than the standard thickness, the detection slider is blocked during the sliding process and stops at the first detection point.

It must be noted that the disclosed embodiments do not limit the scope of this utility model.
