[0002] Some casing materials, such as the bottom shell of a laptop, have some or all of their edges designed as upturned arc edges to achieve good heat dissipation, increase strength, aesthetics, or ergonomics.

[0003] However, at present, it is not easy to intuitively measure whether the curvature of the curved edge area of ​​the shell material meets the requirements of the production process using measuring tools such as calipers, resulting in extremely low efficiency in judging whether the shell material with curved edge area is qualified.

[0004] Therefore, a shell curvature detection fixture that can quickly and intuitively determine whether the curvature of the curved edge area of ​​the shell material is qualified needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a shell material curvature detection fixture to address the defects and deficiencies of the existing technology, thereby solving at least one of the above-mentioned technical problems. It has the advantage of being able to quickly and intuitively determine whether the curvature of the curved edge area of ​​the shell material is qualified.

[0006] To achieve the above objectives, this utility model provides a fixture for detecting the curvature of shell materials, comprising:

[0007] The system comprises a substrate, a clamp, and a straightedge. The clamp is mounted on the substrate for positioning and fixing the shell material. The substrate has several linear guide rails extending from the position away from the shell material to the position closer to the shell material on the outer side of the corresponding arc-shaped edge area, and each guide rail has a calibrated position. The straightedge is movably mounted on the linear guide rails and has an alignment position. The bottom surface of the straightedge near the shell material has a detection surface that matches the curvature of the standard shell material.

[0008] Optionally, the linear guide rail is a groove, and the bottom surface of the ruler at the end away from the detection surface slides into the groove.

[0009] Optionally, the groove extends from the edge region of the substrate to the position corresponding to the shell material; the positioning judgment position is the edge region position of the substrate corresponding to the groove; the end face of the straightedge away from the shell material is a vertical plane, and the alignment position is the end face of the straightedge away from the shell material.

[0010] Optionally, the linear guide rails are at least three, and the at least three linear guide rails are evenly and spaced apart on the outer side of the arc-shaped edge region of the corresponding shell material on the substrate; the number of straightedges is the same as the number of linear guide rails.

[0011] Optionally, the casing material is a computer casing material whose four edge areas are all arc-shaped edge areas, and the clamp is disposed in the middle of the substrate; the substrate is provided with four linear guide rails corresponding to the long side of the computer casing material and three linear guide rails corresponding to the short side of the computer casing material; the number of straightedges is the same as the number of linear guide rails.

[0012] Optionally, the fixture includes: a mold disposed in the middle of the substrate and having a shape adapted to a standard shell material, and a pressure plate disposed above the mold and capable of positioning and fixing the shell material above the mold.

[0013] Optionally, the bearing surface of the mold has at least three positions with first positioning magnetic points, and the lower pressing surface of the pressure plate has second positioning magnetic points corresponding to the first positioning magnetic points, which magnetically engage with them.

[0016] Optionally, the shell curvature detection fixture may further include a drive element that pushes the ruler to move along the linear guide rail.

[0017] Compared with the prior art, the advantages of this application are:

[0018] Because the substrate has several linear guides extending from the outer side of the curved edge area of ​​the shell material, each with a fixed judgment position, and a ruler is movably mounted on the linear guides with an alignment position, and the bottom surface of the ruler near the shell material has a detection surface that matches the curvature of the standard shell material; therefore, if the ruler can be moved along the extension direction of the linear guides to make the fixed judgment position coincide with the alignment position, it means that the detection surface of the ruler is exactly in contact with the curved edge area of ​​the shell material, i.e., the curvature of the curved edge area of ​​the shell material is qualified; if the ruler cannot be moved along the extension direction of the linear guides to make the fixed judgment position coincide with the alignment position, it means that the detection surface of the ruler cannot be in contact with the curved edge area of ​​the shell material, i.e., the curvature of the curved edge area of ​​the shell material is unqualified. This gives it the advantage of being able to quickly and intuitively determine whether the curvature of the curved edge area of ​​the shell material is qualified. Attached Figure Description

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.

[0036] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in this utility model to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0037] Please refer to Figures 1 to 6 This utility model provides a shell curvature detection fixture 100 for detecting whether the curvature of the curved edge region e of the shell material 200 to be tested is qualified. The shell curvature detection fixture includes: a base plate 1, a clamp and a ruler 4.

[0038] The substrate 1 is made of a plate with a certain supporting force and strength, and can be fixed to the corresponding position of the frame (not shown in the figure). A clamp is set on the substrate 1 for positioning and fixing the shell 200. The substrate 1 has several linear guides extending from a position away from the shell 200 to a position closer to the shell 200 on the outer side of the arc-shaped edge region e of the shell 200, and each has a fixed judgment position b. A ruler 4 is movably set on the linear guides and has an alignment position c. The bottom surface of the ruler 4, near the shell 200, has a detection surface d that matches the curvature of the standard shell 200.

[0039] Therefore, if the straightedge 4 can be moved along the linear guide rail to make the calibration judgment position b coincide with the alignment position c, it means that the detection surface d of the straightedge 4 is exactly in contact with the arc-shaped edge region e of the shell material 200, that is, the curvature of the arc-shaped edge region e of the shell material 200 is qualified; if the straightedge 4 cannot be moved along the linear guide rail to make the calibration judgment position b coincide with the alignment position c, it means that the detection surface d of the straightedge 4 cannot be in contact with the arc-shaped edge region e of the shell material 200, that is, the curvature of the arc-shaped edge region e of the shell material 200 is unqualified. This gives it the advantage of being able to quickly and intuitively determine whether the curvature of the arc-shaped edge region e of the shell material 200 is qualified.

[0040] Alternatively, please refer to Figure 2 and Figure 6 In this embodiment, the linear guide is a groove a, and the bottom surface of the ruler 4 away from the detection surface d slides in fit with the groove a. Specifically, the ruler 4 is generally sheet-shaped, and the bottom surface of the end of the ruler 4 away from the detection surface d is flat, and its thickness matches the width of the groove a.

[0041] To facilitate a direct assessment of whether the curvature of the 200mm arc-shaped edge region e of the shell material is up to standard, optionally, please refer to... Figure 2 and Figure 6 In this embodiment, the groove a extends from the edge region of the substrate 1 to the corresponding position of the shell 200; the positioning judgment position b is the edge region position of the groove a corresponding to the substrate 1; the end face of the ruler 4 away from the shell 200 is a vertical plane, and the alignment position c is the end face of the ruler 4 away from the shell 200. Thus, the ruler 4 can enter from the edge region position of the groove a corresponding to the substrate 1 and move along the extension direction of the groove a to abut against the shell 200. If the end face of the ruler 4 away from the shell 200 coincides with the edge region position of the groove a corresponding to the substrate 1 when it abuts against the shell 200, it indicates that the curvature of the arc-shaped edge region e of the shell 200 is qualified.

[0042] To improve the accuracy of the arc detection of the 200 arc-shaped edge region e of the shell material, optionally, please refer to... Figure 4 In this embodiment, there are at least three linear guides, and the number of straightedges 4 is the same as the number of linear guides. Thus, the curvature of the arc-shaped edge region e on one side of the shell 200 is tested at at least three locations to improve the accuracy of the curvature detection of the arc-shaped edge region e of the shell 200. The specific shape of each straightedge 4 can be the same or different, depending on the specific curvature of each location of the arc-shaped edge region e on each side of the standard shell 200.

[0043] Specifically, please refer to Figure 2 and Figure 4 In this embodiment, the casing 200 is a computer casing with four curved edge regions e. The fixture is located in the middle of the substrate 1. The substrate 1 has four linear guides corresponding to the long side 210 of the computer casing and three linear guides corresponding to the short side 220 of the computer casing. The number of rulers 4 is the same as the number of linear guides. Thus, by using the cooperation of four linear guides and four rulers 4 to detect the curvature of the curved edge region e of the long side 210 of the computer casing, and by using the cooperation of three linear guides and three rulers 4 to detect the curvature of the curved edge region e of the short side 220 of the computer casing, the accuracy of detecting the curvature of each curved edge region e of the computer casing can be improved.

[0044] To achieve the positioning and fixing of the shell material 200, optionally, please refer to... Figure 4In this embodiment, the fixture includes a mold 2 and a pressure plate 3. The mold 2 is disposed in the middle of the substrate 1 and has a shape adapted to the standard shell material 200. Specifically, the shape of the mold 2 is adapted to the shape of the assembly groove of the standard shell material 200, so as to fit and support the shell material 200. The pressure plate 3 is disposed above the mold 2 and can position and fix the shell material 200 above the mold 2. In this way, the shell material 200 can be positioned and fixed on the substrate 1, so as to facilitate the detection of the curvature of the arcuate edge region e of the shell material 200 and prevent its displacement.

[0045] To facilitate the quick positioning and clamping of the shell material 200 by the fixture and mold, optionally, please refer to... Figure 5 and Figure 6 In this embodiment, the bearing surface of the mold 2 has at least three positions with first positioning magnetic points 21, and the lower pressing surface of the pressure plate 3 has second positioning magnetic points 31 that magnetically engage with the first positioning magnetic points 21. Thus, through magnetic positioning at at least three positions, the shell material 200 can be quickly positioned and pressed between the fixture and the mold. Specifically, three, four, five, six, seven, eight, or more first positioning magnetic points 21 or second positioning magnetic points 31 can be provided at positions corresponding to the bearing surface of the mold 2 and the lower pressing surface of the pressure plate 3; no specific limitation is made here.

[0046] To facilitate the quick positioning of the shell material 200 on the mold 2, optionally, please refer to... Figure 4 and Figure 5 In this embodiment, the mold 2 is provided with elastic positioning protrusions 22 at the four corners of the outer side of the pressure plate 3, which are used to align and match with the positioning holes o on the shell material 200. In this way, by aligning and matching each positioning hole o of the shell material 200 with the elastic positioning protrusions 22 on the mold 2, the shell material 200 can be quickly positioned on the mold 2.

[0047] To facilitate the operation of pressure plate 3 by staff, optionally, please refer to... Figure 1 In this embodiment, a handle 5 is provided on the upper end surface of the pressure plate 3.

[0048] To improve the efficiency of the shell curvature detection fixture 100, optionally in this embodiment, the shell curvature detection fixture 100 further includes a driving component (not shown in the figure) for pushing the ruler 4 to move along the linear guide rail. Specifically, the driving component can be a stepper motor, and the output end of the servo motor is connected to the ruler 4 through a reduction gearbox to push the ruler 4 to move along the linear guide rail.
