Abstract
Description
Technical Field

[0002] After manufacturing, the laptop casing needs to be inspected for dimensional accuracy to identify defective products and improve the yield rate after assembly. Laptop casings are typically thin-walled components, such as the keyboard cover. These thin-walled components are mainly formed of plastic, with nuts and other connecting parts integrally molded on them for easy assembly. However, during dimensional accuracy inspection of thin-walled components, their thin walls and the susceptibility of the plastic material to deformation mean they are prone to deformation during clamping. Measured deformation can reach 0.5mm to 1.2mm, resulting in significant inspection errors and causing inconvenience in subsequent assembly. Furthermore, inspecting thin-walled components requires manual alignment of the components and positioning parts, leading to low inspection efficiency. Utility Model Content

[0005] The thin-walled part auxiliary inspection fixture according to the embodiments of this utility model has at least the following beneficial effects: By placing the entire thin-walled part in the inspection groove, the positioning is changed from the positioning of a single part to the positioning of the overall outline shape of the thin-walled part, which improves the efficiency of mounting the thin-walled part on the substrate and thus improves the inspection efficiency of the thin-walled part; After the thin-walled part is installed in the inspection groove, the assembly holes on the thin-walled part are basically aligned with the positioning protrusions, thereby improving the installation efficiency of the thin-walled part. At the same time, the relative position of the assembly holes and the positioning protrusions can also play a role in detecting the size of the thin-walled part, thereby improving the inspection efficiency of the thin-walled part; Subsequently, the thin-walled part is clamped together with the substrate by the clamping assembly, which realizes the fixation of the thin-walled part and makes it less prone to deformation. Subsequently, the dimensions between the thin-walled part and the inspection groove can be detected by the plug gauge or other inspection parts, thereby improving the inspection accuracy of the thin-walled part.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0022] Reference Figures 1 to 5As shown in the figure, this utility model embodiment proposes an auxiliary inspection fixture for thin-walled parts. The thin-walled part 500 has assembly holes 510 for assembling other structures. The auxiliary inspection fixture for thin-walled parts includes a base plate 100, a positioning protrusion 200, and a clamping assembly 300. The base plate 100 has a detection groove 110, which is shaped to resemble the thin-walled part 500. The positioning protrusion 200 is disposed in the detection groove 110, and its shape is shaped to resemble the assembly hole 510. The position of the positioning protrusion 200 in the detection groove 110 is shaped to resemble the position of the assembly hole 510 in the thin-walled part 500. The detection groove 110 can position the thin-walled part 500 through the positioning engagement of the positioning protrusion 200 and the assembly hole 510. The clamping assembly 300 is used to clamp the thin-walled part 500.
[0023] The thin-walled part 500 is mainly formed of plastic, with connecting parts such as nuts integrally molded on it. Because the thin-walled part 500 has a thin wall and is made of a relatively soft material, it is prone to deformation. Deformation of the thin-walled part 500 can easily lead to detection errors, resulting in reduced detection accuracy and efficiency. Taking the thin-walled part 500 that mates with a keyboard as an example, it has multiple mounting holes 510 for the keyboard keys to pass through. These mounting holes 510 are similar in shape to the keyboard keys; for example, when the keyboard keys are square, the mounting holes 510 are also square; when the keyboard keys are round, the mounting holes 510 are also round.
[0024] In this embodiment, the substrate 100 is rectangular and made of bakelite. Compared to traditional metal positioning with spacing, the bakelite substrate 100 is less likely to scratch the surface of the plastic part, thus improving the surface quality of the thin-walled part 500. The top surface of the substrate 100 has a detection groove 110, the shape of which is similar to that of the thin-walled part 500. Specifically, the outline shape of the detection groove 110 is basically similar to that of the thin-walled part 500, differing only in size. The detection groove 110 is slightly larger than the thin-walled part 500 to accommodate its placement.
[0025] The shape of the positioning protrusion 200 matches the shape of the assembly hole 510, allowing the assembly hole 510 to be installed on the positioning protrusion 200, thus positioning the thin-walled part 500 and the detection groove 110. The position of the positioning protrusion 200 within the detection groove 110 corresponds to the position of the assembly hole 510 within the thin-walled part 500. This ensures that when the thin-walled part 500 is placed in the detection groove 110, the positioning protrusion 200 can smoothly embed into the assembly hole 510, further improving the relative positional accuracy between the thin-walled part 500 and the detection groove 110, as well as the positioning accuracy of the thin-walled part 500. Compared to the traditional manual alignment method, this positioning method significantly improves detection efficiency and reduces positioning errors caused by human factors.
[0026] The design of the clamping assembly 300 further ensures the stability of the thin-walled component 500 during the inspection process. Specifically, the clamping assembly 300, together with the substrate 100, clamps the thin-walled component 500, achieving a secure clamping of the thin-walled component 500. This clamping method is not only simple and easy to implement, but also ensures that the thin-walled component 500 will not move or deform during the inspection process, thereby improving the accuracy of the inspection.
[0027] It is understandable that by placing the thin-walled component 500 as a whole in the detection groove 110, the positioning is changed from a single part to the overall contour of the thin-walled component 500. This makes the installation of the thin-walled component 500 on the substrate 100 more efficient, resulting in higher detection efficiency. After the thin-walled component 500 is installed in the detection groove 110, the mounting holes 510 on the thin-walled component 500 are basically aligned with the positioning protrusions 200, thereby improving the installation efficiency of the thin-walled component 500. At the same time, the relative position of the mounting holes 510 and the positioning protrusions 200 can also play a role in detecting the dimensions of the thin-walled component 500, improving the detection efficiency of the thin-walled component 500. Subsequently, the thin-walled component 500 is clamped together with the substrate 100 by the clamping assembly 300, thus fixing the thin-walled component 500 and preventing it from deforming. Afterwards, the dimensions between the thin-walled component 500 and the detection groove 110 can be detected using plug gauges or other detection tools, improving the detection accuracy of the thin-walled component 500.
[0028] Reference Figure 1 As shown, in some specific embodiments of this utility model, the positioning protrusion 200 is provided at the corner of the bottom surface of the detection groove 110.
[0029] It is understandable that by setting the positioning protrusions 200 at the corners of the bottom surface of the inspection groove 110, when the thin-walled part 500 is placed into the inspection groove 110, the corner positioning protrusions 200 position the corners of the thin-walled part 500, thereby achieving the positioning of the thin-walled part 500. The positioning protrusions 200 can more reliably cooperate with the assembly holes 510 on the thin-walled part 500 to achieve precise positioning. In this embodiment, the thin-walled part auxiliary inspection fixture includes at least four positioning protrusions 200, which are respectively located at the four corners of the bottom surface of the groove, so that the four corners of the thin-walled part 500 are respectively positioned and fixed by the four positioning protrusions 200, thereby improving the inspection accuracy.
[0030] Reference Figure 1 , Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the thin-walled part auxiliary inspection tool also includes a magnetic suction member 400. The magnetic suction member 400 is disposed on the bottom surface of the detection groove 110, and the top surface of the magnetic suction member 400 does not exceed the bottom surface of the groove. The magnetic suction member 400 is used to magnetically attract the thin-walled part 500.
[0031] It is understandable that the magnetic suction component 400 provides additional adsorption force for the thin-walled component 500 within the detection slot 110, further enhancing its stability during the detection process. When the thin-walled component 500 is placed in the detection slot 110, the magnetic suction component 400 magnetically attracts it, ensuring it adheres tightly to the bottom surface of the slot 110, preventing movement or shaking due to vibration or external forces. Furthermore, the top surface of the magnetic suction component 400 does not extend beyond the bottom surface of the slot, thus avoiding interference with the fit between the thin-walled component 500 and the detection slot 110. This ensures the thin-walled component 500 is accurately placed within the detection slot 110, achieving precise positioning and engagement with the positioning protrusion 200. Compared to traditional mechanical clamping, this magnetic adsorption method is gentler and will not scratch or damage the surface of the thin-walled part 500, thus better protecting its surface quality. It is especially suitable for thin-walled parts 500 made of softer materials such as plastics. Furthermore, the adsorption force of the magnetic component 400 can be rationally selected and adjusted according to the weight and material of the thin-walled part 500 to meet the inspection needs of different types of thin-walled parts 500, improving the applicability and flexibility of the auxiliary inspection tool for thin-walled parts.
[0032] Reference Figure 1 As shown, in some specific embodiments of this utility model, the magnetic suction member 400 forms a first projection on the bottom surface of the groove, the positioning protrusion 200 forms a second projection on the bottom surface of the groove, the distance between the first projection and the second projection is L, and the thin-walled auxiliary inspection tool satisfies: 15mm≥L.
[0033] It is understandable that by reasonably controlling the distance L between the first and second projections, it is possible to ensure that the arrangement of the magnetic suction component 400 and the positioning protrusion 200 on the bottom surface of the detection slot 110 will not interfere with each other, while also allowing each component to fully perform its function. When the thin-walled part auxiliary fixture satisfies the condition that 15mm ≥ L, the magnetic attraction force generated by the magnetic suction component 400 will not adversely affect the positioning and fit between the positioning protrusion 200 and the assembly hole 510 on the thin-walled part 500, ensuring that the positioning protrusion 200 can be accurately embedded in the assembly hole 510, achieving accurate positioning of the thin-walled part 500. At the same time, this arrangement also makes more rational use of the space within the detection slot 110, providing favorable conditions for the placement and detection of the thin-walled part 500. In different detection scenarios for the thin-walled part 500, the size of L can be flexibly adjusted according to factors such as the size and shape of the thin-walled part 500 and the position of the assembly hole 510 to adapt to various detection needs and improve the versatility and detection accuracy of the thin-walled part auxiliary fixture.
[0034] Reference Figure 4 and Figure 5As shown, in some specific embodiments of this utility model, the assembly error between the positioning protrusion 200 and the assembly hole 510 is X, and the auxiliary inspection fixture for thin-walled parts satisfies: X≤0.05mm. Strictly controlling the assembly error X between the positioning protrusion 200 and the assembly hole 510 to ensure X≤0.05mm guarantees a high level of positioning accuracy for the thin-walled part 500 within the inspection groove 110. Accurate positioning is one of the key factors ensuring the reliability of the inspection results during the inspection of the thin-walled part 500. If the assembly error is too large, it will cause the position of the thin-walled part 500 within the inspection groove 110 to shift, thereby affecting the accuracy of subsequent dimensional inspections of the thin-walled part 500 and reducing the inspection quality. Controlling the assembly error to within 0.05mm can effectively reduce this positioning deviation, making the relative positional relationship between the thin-walled part 500 and the detection groove 110 more accurate. This provides a reliable guarantee for using plug gauges and other detection parts to inspect the dimensions between the thin-walled part 500 and the detection groove 110, thereby improving the detection accuracy of the thin-walled part 500 and the product quality.
[0035] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the ratio of the height of the positioning protrusion 200 to the wall thickness of the thin-walled component 500 is Y1, and the auxiliary gauge for the thin-walled component satisfies: 1.7 ≥ Y1 ≥ 1.3; or, the difference between the height of the positioning protrusion 200 and the wall thickness of the thin-walled component 500 is Y2, and the auxiliary gauge for the thin-walled component satisfies: 5mm ≥ Y2 ≥ 3mm. By setting the ranges of Y1 and Y2, a good positioning fit can be ensured between the positioning protrusion 200 and the thin-walled component 500. When the ratio of Y1 is used, within the range of 1.7 ≥ Y1 ≥ 1.3, the height of the positioning protrusion 200 can ensure a stable positioning connection with the assembly hole 510 on the thin-walled component 500, without causing damage to the thin-walled component 500 or affecting its assembly in other aspects due to excessive height. When using the difference relationship of Y2, a range of 5mm ≥ Y2 ≥ 3mm ensures a suitable gap between the positioning protrusion 200 and the thin-walled part 500. This facilitates the placement and removal of the thin-walled part 500 while ensuring effective positioning of the thin-walled part 500 by the positioning protrusion 200 during inspection. This diverse parameter setting method allows for flexible selection of the appropriate height design of the positioning protrusion 200 based on the material, wall thickness, and size characteristics of different types of thin-walled parts 500, improving the applicability of the auxiliary inspection tool for thin-walled parts and the accuracy of inspection.
[0036] Reference Figure 1As shown, in some specific embodiments of this utility model, the substrate 100 further includes a clearance groove 120, which is connected to the detection groove 110 and used to remove the thin-walled component 500 from the detection groove 110. The design of the clearance groove 120 facilitates the removal of the thin-walled component 500 from the detection groove 110. After the detection of the thin-walled component 500 is completed, it may be difficult to directly remove the thin-walled component 500 due to the possible degree of contact between the thin-walled component 500 and the detection groove 110. However, the clearance groove 120, connected to the detection groove 110, forms an additional spatial channel, through which the operator can more easily access the edge or specific part of the thin-walled component 500, thereby easily removing the thin-walled component 500 from the detection groove 110, avoiding damage to the thin-walled component 500 or affecting the detection results due to forced removal. At the same time, the existence of the clearance groove 120 will not interfere with the normal detection function of the detection groove 110, ensuring the overall performance and detection efficiency of the thin-walled component auxiliary inspection tool.
[0037] Reference Figure 1 , Figure 4 and Figure 5 As shown, in some specific embodiments of this utility model, the substrate 100 includes a first detection groove and a second detection groove. The first detection groove is used to detect a first thin-walled component, and the second detection groove is used to detect a second thin-walled component. The relative positions of the first and second detection grooves are designed to resemble the relative positions of the first and second thin-walled components during assembly. This arrangement allows the thin-walled component auxiliary inspection fixture to simultaneously inspect two different types of thin-walled components 500 and simulates the relative positional relationship of these two thin-walled components 500 during actual assembly. In actual production, many products are assembled from multiple thin-walled components 500, and the relative positional accuracy between the various thin-walled components 500 has a significant impact on the overall performance and quality of the product. By setting the first and second detection grooves on the substrate 100 and making their relative positions resemble the relative positions of the first and second thin-walled components during assembly, the dimensions of the two thin-walled components 500 and their relative positions can be detected simultaneously during the inspection process. This allows for timely detection of potential assembly errors, enabling adjustments and corrections in advance, thereby improving product assembly quality and production efficiency. This integrated inspection design reduces inspection steps and time, and improves the functionality and practicality of auxiliary inspection fixtures for thin-walled parts. In this embodiment, the number of inspection slots is 5, to inspect 5 different types of thin-walled parts 500.
[0038] Reference Figure 4 and Figure 5As shown, in some specific embodiments of this utility model, a thermal compensation gap R is provided between the sidewall of the detection groove 110 and the outer peripheral wall of the thin-walled component 500, and the auxiliary gauge for the thin-walled component satisfies: 0.12mm ≥ R ≥ 0.08mm. The thermal compensation gap R is set to address the thermal expansion and contraction of the thin-walled component 500 during the detection process due to temperature changes. Since the thin-walled component 500 is mainly made of materials such as plastic, which have relatively large coefficients of thermal expansion, the dimensions of the thin-walled component 500 will change to some extent when the temperature changes. If there is no gap or the gap is too small between the sidewall of the detection groove 110 and the outer peripheral wall of the thin-walled component 500, when the thin-walled component 500 expands due to heat, it will be squeezed by the detection groove 110, which may cause the thin-walled component 500 to deform, affecting the accuracy of the detection results; while when the thin-walled component 500 cools and contracts, it may become loose with the detection groove 110, leading to inaccurate positioning. By setting a thermal compensation gap of 0.12mm≥R≥0.08mm, a certain amount of expansion or contraction space can be provided for the thin-walled part 500 when its size changes due to temperature changes. This ensures that the thin-walled part 500 and the detection groove 110 always maintain good contact and positioning, and the detection accuracy will not be affected by thermal expansion and contraction. This improves the applicability and detection reliability of the auxiliary inspection tool for thin-walled parts in different temperature environments.
[0039] Reference Figure 2 and Figure 3 As shown, in some specific embodiments of this utility model, the clamping assembly 300 includes a first clamping member 310 and a second clamping member 320. The first clamping member 310 and the second clamping member 320 are respectively disposed on two opposite sides of the detection groove 110. The first clamping member 310 includes a clamping seat 311, a clamping rod 312, and a first clamping part 313. The clamping seat 311 is connected to the substrate 100, the clamping rod 312 is rotatably connected to the clamping seat 311, and the first clamping part 313 is disposed at one end of the clamping rod 312 for clamping the thin-walled member 500 in the detection groove 110. The substrate 100... The 00 also includes a mounting groove 130, which is connected to the detection groove 110. The bottom surface of the mounting groove 130 is higher than the bottom surface of the detection groove 110. The depth difference between the bottom surface of the mounting groove 130 and the bottom surface of the detection groove 110 along the groove depth direction is equal to the wall thickness of the thin-walled member 500. The second clamping member 320 includes a rotating shaft 321 and a second clamping part 322. The second clamping part 322 is rotatably connected to the rotating shaft 321. The second clamping part 322 can rotate from inside the mounting groove 130 to inside the detection groove 110 to clamp the thin-walled member 500 inside the detection groove 110.
[0040] In this embodiment, the first clamping member 310 is fixed to the substrate 100 by the clamping seat 311, the clamping rod 312 can rotate around the clamping seat 311, and the first clamping part 313 is disposed at one end of the clamping rod 312. By rotating the clamping rod 312, the first clamping part 313 can move closer to or further away from the thin-walled member 500 in the detection groove 110, thereby flexibly separating or clamping the thin-walled member 500 in the detection groove 110, making it more convenient to use. The mounting groove 130 is connected to the detection groove 110, and the height difference between its bottom surface and the wall thickness of the thin-walled component 500 is equal. When the thin-walled component 500 is installed in the detection groove 110, the bottom surface of the mounting groove 130 is flush with the top surface of the thin-walled component 500. The second clamping part 322 of the second clamping member 320 is rotatably connected via a rotating shaft 321, allowing it to rotate from the mounting groove 130 into the detection groove 110 and clamp the top surface of the thin-walled component 500 through the bottom surface of the detection groove 110, thus achieving clamping of the thin-walled component 500. The second clamping member 320 cooperates with the first clamping member 310 to firmly clamp the thin-walled component 500 from two opposite directions. This clamping method not only ensures that the thin-walled part 500 remains stable during the inspection process, avoiding the impact of movement or shaking on the inspection accuracy, but also makes the operation convenient and flexible. It can be appropriately adjusted according to the size and shape of the thin-walled part 500, improving the ease of use and inspection accuracy of the auxiliary inspection tool for thin-walled parts.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
