Technical Field

[0001] This utility model relates to the field of measurement auxiliary tools, specifically a high-precision square measuring plate for irregular products. Background Technology

[0002] In the manufacturing industry, to ensure the assembly accuracy of parts, it is necessary to measure the manufactured parts to ensure that their dimensions meet standards. For products with regular shapes, such as cuboids and prisms, measurements can be quickly completed using traditional measuring tools (such as calipers and rulers).

[0003] However, for irregularly shaped products with complex forms, such as irregularly shaped plastic parts and mobile phone cases, traditional measuring tools can easily lead to significant deviations between the measurement results and the actual dimensions of the product. This is because traditional measuring tools are difficult to conform to the irregular contours of irregular products. In order to obtain accurate data for multiple key dimensions, operators need to change measuring tools and measuring angles multiple times to measure multiple sets of data. This process is cumbersome, consumes a lot of time and manpower, and has low measurement efficiency. Moreover, the data obtained often requires complex calculations and conversions to obtain the actual dimensions of the product, making it impossible to quickly and intuitively determine whether the product dimensions meet the dimensional standards. Therefore, it is necessary to develop a measuring tool that can quickly, accurately, and intuitively determine whether a product meets the dimensional standards. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision square measuring plate for irregular products. It is easy to operate; simply press the product gently to embed it into the measuring slot and compare the measurements to determine whether all dimensions of the product meet the dimensional standards. This greatly improves measurement efficiency and allows for a direct visual assessment of whether the product dimensions meet the requirements, thus solving the problem of low measurement efficiency of traditional measuring tools mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision square measuring plate for irregular products includes a measuring plate body, the surface of which has an irregularly curved measuring groove. The shape of the measuring groove matches the shape of the product to determine whether the product meets the size standard.

[0007] Preferably, the measuring groove includes a first right-angle segment, a straight segment, a circular arc segment, an arc segment, and a second right-angle segment connected in sequence.

[0009] Preferably, the straight segment is in the shape of a line, the arc segment is in the shape of an arch, and the arc segment is in the shape of an arc.

[0010] Preferably, the middle section of the straight segment is recessed towards one or both sides of the groove wall to form an extraction groove.

[0011] Preferably, the groove width of the arc segment is increased so that its groove width is greater than the width of the product.

[0012] Preferably, the extraction slot is provided with an extraction component, which includes an insert embedded in the extraction slot, a hook connected to the bottom end of the insert, and a handle connected to the top end of the insert, wherein the hook extends to the bottom of the straight section.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-2 A high-precision square measuring plate for irregular products includes a measuring plate body 1. The surface of the measuring plate body 1 is provided with a measuring groove 2 that is irregularly curved. The shape of the measuring groove 2 matches the shape of the product so that the product can be embedded. The product is judged to meet the size standard by comparing the width of each part of the embedded product with the width of each part of the measuring groove 2, and by comparing the length of the product with the length of the measuring groove 2, or by comparing the angles.

[0024] When determining whether a product's dimensions are acceptable, if the product cannot be fully or partially inserted into the measuring groove 2, the corresponding part of the product is considered too large. If the product can be inserted into the measuring groove 2, but the gap between the measuring groove 2 wall and the product's outer wall is large, the corresponding part of the product is considered too small. If there are gaps between the end of the measuring groove 2 and the two ends of the product, the end dimensions of the product are considered too small. All of these results can quickly detect that the product does not meet the size standard and is a defective product. If the product fits perfectly into the measuring groove 2, and the outer wall of the product is in close contact with the measuring groove 2 wall, and there are no gaps between the two ends of the product and the two ends of the measuring groove 2, then the product meets the size requirements and is a good product.

[0025] The above measurement operation is simple and convenient, requiring no significant time or manpower. Simply press the product gently to embed it into the measuring slot 2 and compare the measurements to determine whether all dimensions of the product conform to the dimensional standards. This greatly improves measurement efficiency and ensures high accuracy. By directly comparing the product with the measuring slot 2, it is easy to see whether the product dimensions meet the requirements, without having to compare all measurement results with standard dimensions. This allows for the rapid screening of good and defective products, meeting the needs for large-scale, high-efficiency measurement of irregular products in various scenarios.

[0026] In this embodiment, the measuring plate body 1 is made of high-strength alloy material, which makes it less prone to deformation, dimensionally stable, and durable for frequent use, while also ensuring the accuracy of the measurement results; the design of the measuring groove 2 is based on the shape of the irregular sheet product being measured and its tolerance range, which can effectively control the out-of-tolerance measurement of the product.

[0027] In this embodiment, the wall of the measuring tank 2 is coated with a chemically bonded wear-resistant coating. The chemically bonded wear-resistant coating is a wear-resistant coating adhesive formulated using various resins and elastomers, which can reduce the phenomenon of surface damage when the product comes into contact with the measuring tank 2. At the same time, the chemically bonded wear-resistant coating can reduce the wear generated when the wall of the measuring tank 2 comes into contact with the product, thereby increasing the number of uses of the measuring tank 2.

[0028] Please refer to 1-2. The measuring groove 2 includes a first right-angle segment 21, a straight segment 22, an arc segment 23, an arc segment 24, and a second right-angle segment 25 connected in sequence. The first right-angle segment 21 and the second right-angle segment 25 are both L-shaped, and the right angles of the first right-angle segment 21 and the second right-angle segment 25 are rounded. The straight segment 22 is straight, the arc segment 23 is arched, and the arc segment 24 is arc-shaped.

[0029] In this embodiment, the measuring groove 2 can measure a variety of products. The shape of any segment of the measuring groove 2, such as the first right-angle segment 21, the straight segment 22, the arc segment 23, the arc segment 24, and the second right-angle segment 25, is adapted to the shape of the corresponding product, and the corresponding product can be measured individually. Furthermore, any of the above-mentioned adjacent segments of the measuring groove 2 can be combined for measurement, which improves the versatility of the measuring groove 2 and can meet diverse measurement needs.

[0030] The middle section of the straight segment 22 is recessed to one or both sides of the groove wall to form a take-out groove 221. When the product is embedded in the measuring groove 2, the product can be easily taken out through the take-out grooves 221 on both sides of the straight segment 22, avoiding the problem that the product is difficult to take out due to the product being stuck in the measuring groove 2 and being too tightly engaged with the measuring groove 2.

[0031] The groove width of the arc segment 24 is increased to be larger than the width of the product. At the same time, the curvature of the arc segment 24 must be kept within the radius tolerance. This is because the product's radius will be different due to tempering after cold forming. The increased groove width of the arc segment 24 can avoid the problem that the product's radius cannot be inserted into the measuring groove 2 due to radius issues, thus reducing measurement defects.

[0032] Example 2

[0033] Please see Figure 3In Embodiment 2, the structure of the measuring piece is largely the same as that in Embodiment 1. The difference lies in that, to improve the measurement accuracy of the straight section 22 of the measuring groove 2 and to prevent the removal groove 221 from affecting the judgment of product dimensions, an extraction component 3 is provided in the removal groove 221 in Embodiment 2. The extraction component 3 includes an insert 31 embedded in the extraction groove 221, a hook 32 connected to the bottom of the insert 31, and a handle 33 connected to the top of the insert 31. The hook 32 extends to the bottom of the straight section 22, and the side of the insert 31 can cooperate with the side wall of the straight section 22 to measure the product dimensions. After the product has been tested, the hook 32 simultaneously hooks the product up by lifting the insert 31 from the extraction groove 221 using the handle 33, thereby conveniently removing the product from the measuring groove 2.

[0034] In this embodiment 2, there are two hook feet 32, which are arranged opposite each other at the bottom of the insert 31. However, this embodiment does not limit the number of hook feet 32, and the number of hook feet 32 ​​can be set to one or more.

[0035] Please see Figure 3 The groove 221 has grooves on both sides, and the insert 31 has a sliding strip on both sides that fits in the groove. The sliding strip and the groove cooperate to make the insert 31 stably lifted or embedded, and the groove has a positioning function for the insert 31.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
