[0036] The image measuring instrument is a new type of high-precision, high-tech measuring instrument that integrates optical, mechanical, electrical, and computer image technology. The optical microscope uses a high-magnification optical magnification image of the object to be measured, and the magnified object image is sent to the computer through the CCD camera system. It can efficiently detect the contour and surface shape, size, angle and position of various complex workpieces, especially the microscopic inspection and quality control of precision parts. However, the product to be measured may shake when measured in a free state, affecting the accuracy of the measurement.

[0037] In order to solve the above problems, Figure 1-Figure 4As shown, the present embodiment provides an auxiliary tooling for dimension measurement, which comprises a base plate 1 and a cover plate 2. A limiting groove 11 is provided on the surface of the base plate 1, and the product to be measured is placed in the limiting groove 11. The shape and size of the limiting groove 11 are the same as those of the product to be measured. A positioning PIN 3 is convexly provided on the base plate 1, and a first magnetic component 12 is also provided on the base plate 1; a limiting cavity 211 is provided through the surface of the cover plate 2, and the shape and size of the limiting cavity 211 are the same as those of the limiting groove 11. A positioning hole 221 is provided on the cover plate 2, and a second magnetic component 23 is provided on the cover plate 2; when the cover plate 2 is covered on the base plate 1, the positioning PIN 3 is inserted into the positioning hole 221, the first magnetic component 12 and the second magnetic component 23 are attracted to each other, the limiting cavity 211 is directly opposite to the limiting groove 11, and the side wall of the product to be measured abuts against the cavity wall of the limiting cavity 211.

[0038] Before measuring the size of the product to be measured, place it in the limiting groove 11 of the base plate 1. Since the limiting groove 11 has the same shape and size as the product to be measured, the product to be measured is initially clamped on the base plate 1. Then the cover plate 2 is covered on the base plate 1. The positioning PIN 3 on the base plate 1 cooperates with the positioning hole 221 on the cover plate 2, and the cover plate 2 can be quickly aligned and fixed with the base plate 1. At this time, the limiting cavity 211 is directly opposite to the limiting groove 11, and the side wall of the product to be measured abuts against the cavity wall of the limiting cavity 211, that is, the product to be measured is accurately placed in this auxiliary tooling. Due to the attraction between the first magnetic suction member 12 and the second magnetic suction member 23, the overall stability of the auxiliary tooling is further enhanced, ensuring that the base plate 1 and the cover plate 2 will not move relative to each other, that is, ensuring that the product to be measured will not be displaced or shaken during the measurement process, ensuring the accuracy of the measurement. The entire auxiliary tooling has a simple structure and is easy to operate. It only requires placing the product to be measured into the limiting groove 11 and then covering it with the cover plate 2. No complicated adjustment and fixing steps are required, which greatly improves the efficiency of measurement.

[0039] It should be noted that the shapes and sizes of the limiting groove 11 and the limiting cavity 211 can be customized according to different products to be measured. The customized design enables the auxiliary tooling to be applied to different products, thereby improving the versatility of the auxiliary tooling.

[0040] In this embodiment, the cavity wall of the limiting cavity 211 is provided with a flexible buffer layer, which can reduce the direct friction and collision between the product to be measured and the cavity wall of the limiting cavity 211, thereby preventing damage or scratches on the surface of the product to be measured; and the provision of the flexible buffer layer can make the abutment between the product to be measured and the cover plate 2 tighter and less prone to shaking, which helps to maintain the stability of the product to be measured during the measurement process and improve the measurement accuracy.

[0041] Specifically, the flexible buffer layer may be a rubber layer, which is not limited in this embodiment.

[0042] Specifically, Figure 1-Figure 3 As shown, there are multiple limit grooves 11 and multiple limit cavities 211. When the cover plate 2 is covered on the bottom plate 1, multiple limit grooves 11 and multiple limit cavities 211 are opposite to each other, and the opposite limit grooves 11 and limit cavities 211 have the same shape and size. By setting multiple limit grooves 11 and limit cavities 211, multiple products to be measured can be fixed and measured at the same time, thereby improving the efficiency of measurement. By designing limit grooves 11 and limit cavities 211 of different shapes and sizes, this auxiliary tooling can simultaneously assist in measuring products of different specifications.

[0043] In this embodiment, if Figure 2 , Figure 3 As shown, there are multiple positioning PINs 3 and multiple positioning holes 221. When the cover plate 2 is covered on the bottom plate 1, multiple positioning PINs 3 are inserted into the multiple positioning holes 221 in a one-to-one correspondence. Through the one-to-one correspondence between multiple positioning PINs 3 and corresponding positioning holes 221, it is possible to ensure that the cover plate 2 is covered at an accurate position on the bottom plate 1, avoid errors that may occur in single-point positioning, improve the accuracy of overall positioning, and reduce assembly difficulty and time.

[0044] Specifically, there are multiple first magnetic members 12 and multiple second magnetic members 23. When the cover plate 2 is placed on the bottom plate 1, multiple first magnetic members 12 and multiple second magnetic members 23 are attracted to each other in a one-to-one correspondence. The interaction between multiple magnetic members can generate a stronger magnetic attraction force, making the connection between the cover plate 2 and the bottom plate 1 more secure. Through the distribution of multiple magnetic members, it can be ensured that when the cover plate 2 is connected to the bottom plate 1, the stress can be evenly distributed.

[0045] In this embodiment, if Figure 4 As shown, a first placement groove 13 is provided on the surface of the bottom plate 1, and the first magnetic member 12 is arranged in the first placement groove 13, and the end surface of the first magnetic member 12 is not higher than the surface of the bottom plate 1. The end surface of the first magnetic member 12 is not higher than the surface of the bottom plate 1, which can ensure that when the cover plate 2 is covered on the bottom plate 1, a close fitting surface can be formed, so that the cover plate 2 can fit the bottom plate 1.

[0046] Similarly, if Figure 4 As shown, a second placement groove 24 is opened on the surface of the cover plate 2, and the second magnetic component 23 is arranged in the second placement groove 24. The end surface of the second magnetic component 23 is not higher than the surface of the cover plate 2. The end surface of the second magnetic component 23 is not higher than the surface of the cover plate 2, which can ensure that when the cover plate 2 is covered on the base plate 1, a tight fitting surface can be formed, so that the cover plate 2 can fit the base plate 1.

[0047] Specifically, Figure 1 , Figure 3 , Figure 4As shown, the cover plate 2 includes a cover plate body 21 and a fixing part 22, the cover plate body 21 and the fixing part 22 are detachably connected, a limit cavity 211 is provided on the cover plate body 21, and a fixing hole is provided on the fixing part 22, wherein the cover plate body 21 and the bottom plate 1 are both made of transparent acrylic. The cover plate body 21 and the bottom plate 1 are made of transparent acrylic, and the limit cavity 211 is provided on the cover plate body 21, that is, the product to be measured is located on the bottom plate 1 and in the cover plate body 21, and the transparent acrylic material has strong light transmittance, which can meet the bottom light of the image measurement equipment for measurement; the cover plate 2 is designed to consist of two parts, the cover plate body 21 and the fixing part 22, which can be formed separately with different materials, and the fixing part 22 is not limited to being made of transparent acrylic material, which can reduce the loss of transparent acrylic material.

[0048] In this embodiment, the fixing part 22 is made of metal. Compared with the transparent acrylic material, the fixing part 22 made of metal is less likely to be deformed or damaged, thereby ensuring the stability and durability of the fixing part 22. When the positioning PIN 3 is frequently inserted into the positioning hole 221 of the fixing part 22, the fixing part 22 is not prone to wear or deformation.

[0049] Specifically, Figure 4 As shown, the cover body 21 is provided with a first receiving hole, and the fixing part 22 is provided in the first receiving hole and fixedly connected to the cover body 21 by bolts. The bolt connection is stable and simple, which can ensure the tight connection between the fixing part 22 and the cover body 21, and is not easy to loosen or fall off, and the installation method is simple, which reduces the time required for assembly.

[0050] Similarly, the bottom plate 1 is detachably connected to the positioning PIN 3. The positioning PIN 3 can be formed using a material different from that of the bottom plate 1, and is not limited to being made of a transparent acrylic material, which can reduce the loss of the transparent acrylic material.

[0051] In this embodiment, the positioning PIN 3 is made of metal. Compared with transparent acrylic material, the positioning PIN 3 made of metal is less likely to be deformed or damaged, thereby ensuring the stability and durability of the positioning PIN 3. When the positioning PIN 3 is frequently inserted into the positioning hole 221 of the fixing part 22, the positioning PIN 3 is not prone to wear or deformation.

[0052] Specifically, Figure 4 As shown, the bottom plate 1 is provided with a second receiving hole, the positioning PIN 3 is provided in the second receiving hole, and is fixedly connected to the bottom plate 1 by bolts. The bolt connection is stable and simple, which can ensure the tight connection between the positioning PIN 3 and the bottom plate 1, and is not easy to loosen or fall off, and the installation method is simple, which reduces the time required for assembly.

[0053] In an alternative embodiment, if Figure 1 , Figure 3 As shown, a handle 4 is provided on the cover plate 2, and the handle 4 is located on the side of the cover plate 2 away from the bottom plate 1. The handle 4 provides an intuitive and easy-to-hold part for the operator, so that the operator can easily lift the mobile cover plate 2, making the operation of the operator easier.

[0054] In another optional embodiment, buckle grooves are provided on opposite sides of the cover plate 2. The buckle grooves provide a clear gripping point for the operator, so that the operator can easily grasp and move the cover plate 2, and the buckle grooves are better hidden, which increases the aesthetics of the cover plate 2.

[0055] Furthermore, the wall surface of the buckle groove is provided with an anti-skid pad. The anti-skid pad can effectively increase the friction force, prevent the operator's hand from slipping when moving the cover plate 2, and improve the safety and stability of the operation. Specifically, the anti-skid pad is made of materials such as rubber and silicone.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
