[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0033] like Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, an auxiliary quality inspection fixture for inspecting a bent-formed protective cover 200 is provided, hereinafter referred to as the fixture. The protective cover 200 has an arc-shaped structure and an opening. The fixture includes: a reference plate 110, the edge of which is provided with a marked position 1101, and the reference plate 110 has an outer surface adapted to the slope of the protective cover 200, so that the inner wall of the protective cover 200 extending in the inclined direction can abut against the outer surface of the reference plate; and a limiting block 120, which is detachably connected to the reference plate 110, and the limiting block 120 is provided with a first positioning structure 130, which penetrates the protective cover 200, so that the positions of the protective cover 200 and the reference plate 110 are relatively fixed.

[0034] In this embodiment, combined with Figure 2As shown, the fixture mainly includes a reference plate 110 and a limiting block 120. The reference plate 110 is an arc-shaped plate adapted to the curvature of the inner wall of the protective cover 200. The outer surface of the reference plate 110 is precision machined so that it can fit tightly against the inner wall of the protective cover 200 extending in the inclined direction. The edge of the reference plate 110 is marked with a position 1101 to indicate the correct placement position of the protective cover 200 on the reference plate 110, and at the same time, it is convenient for the inspection personnel to visually observe the fit between the protective cover 200 and the reference plate 110. The limiting block 120 is detachably connected to the reference plate 110, which facilitates the adjustment of the position of the limiting block 120 so that the limiting block 120 matches the inner surface of the protective cover 200, making the positioning of the protective cover 200 more stable. The protective cover 200 is provided with a protective cover positioning hole 201, and the limiting block 120 is provided with a first positioning structure 130, which can be a positioning pin or positioning post that passes through the protective cover positioning hole 201. The diameter and length of the positioning pin or positioning post are designed according to the hole diameter of the positioning hole 201 of the cover and the wall thickness of the cover 200 to ensure that the first positioning structure 130 can firmly penetrate the cover 200, so that the position of the cover 200 relative to the reference plate 110 is fixed.

[0035] In this embodiment, the limiting block 120 can be made of high-strength plastic material, which has good self-lubricating and impact resistance properties, and can effectively reduce friction and wear between it and the protective cover 200. The reference plate 110 can be made of high-strength aluminum alloy material, which has good rigidity and wear resistance, and can ensure its dimensional stability during long-term use.

[0036] When inspecting the protective cover 200, first connect the limiting block 120 to the reference plate 110, then place the reference plate 110 on the inspection platform, ensuring its outer side faces upwards and the edge marking position 1101 of the reference plate 110 is clearly visible. Place the protective cover 200 to be inspected on the reference plate 110 along its inclined direction, with the first positioning structure 130 of the limiting block 120 penetrating through the protective cover 200. After the position of the protective cover 200 is relatively fixed, ensure that the inner wall of the protective cover 200 is tightly fitted to the outer side of the reference plate 110. At this point, by observing the marking position 1101 on the edge of the reference plate 110, it is possible to preliminarily determine whether the curvature and inclination of the protective cover 200 meet the requirements.

[0037] By fitting the reference plate 110 to the inner wall of the protective cover 200 and positioning it with the limiting block 120, the protective cover 200 can be fixed quickly and accurately, greatly shortening the detection time and improving the detection efficiency.

[0038] The outer surface of the reference plate 110 is precision machined to fit tightly against the inner wall of the protective cover 200, ensuring the accuracy of the shape and size of the protective cover 200 during the testing process. At the same time, the first positioning structure 130 of the limiting block 120 can firmly penetrate the protective cover 200, further ensuring the stability of the protective cover 200 during the testing process.

[0039] This fixture can be customized according to the different curvatures and slopes of the protective cover 200, and has wide applicability, which can meet the testing needs of various specifications of protective covers 200.

[0040] This fixture has a simple structure and is easy to operate. It does not require complicated equipment and tools, and testing personnel can master its use after simple training, thus reducing testing costs.

[0041] Furthermore, the outer side of the reference plate 110 is provided with a limiting groove 1102, the extension direction of the limiting groove 1102 is adapted to the slope of the protective cover 200, and the bottom surface of the protective cover 200 abuts against the bottom of the limiting groove 1102.

[0042] In this embodiment, the limiting groove 1102 is an arc-shaped groove adapted to the bottom surface of the protective cover 200, and its extending direction is adapted to the slope of the protective cover 200. The depth of the limiting groove 1102 can be, for example, 5mm, and the width can be 10mm, ensuring that the bottom surface of the protective cover 200 is tightly fitted with the bottom of the limiting groove 1102. The limiting groove 1102 has a positioning function, and it is completely adapted to the inner cavity of the protective cover 200. By using this fixture, the arc, slope, and other parameters of the protective cover 200 can be detected quickly and accurately, improving detection efficiency and accuracy.

[0043] Furthermore, the side of the reference plate 110 corresponding to the opening of the cover 200 is the free side 1104, and a limiting block 120 is provided on the side of the reference plate 110 opposite to the free side 1104.

[0044] In this embodiment, the reference plate 110 is a circular structure of the contoured protective cover 200, and the limiting block 120 is set on the side of the reference plate 110 opposite to the free side 1104, so that the limiting block 120 can be positioned with the middle position of the protective cover 200, and the positioning is more secure.

[0045] Furthermore, such as Figure 3 As shown, a blind hole is provided on the reference plate 110, and a second positioning structure 140 is provided in the blind hole. The second positioning structure 140 passes through the limiting block 120 to connect to the limiting block 120.

[0046] In this embodiment, a portion of the second positioning structure 140 is placed inside the blind hole, which does not disrupt the flatness of the bottom of the reference plate 110, allowing the reference plate 110 to be placed more stably on the testing platform.

[0047] Furthermore, the second positioning structure 140 includes two vertical positioning posts, and the limiting block 120 is provided with two vertical positioning post holes 1201, with the outer surface of the vertical positioning post fitting against the inner surface of the vertical positioning post hole 1201.

[0048] In this embodiment, we continue to combine Figure 3 As shown, the reference plate 110 has two vertical positioning holes 1103 with a certain depth but not penetrating through. The vertical positioning holes 1103 are distributed on one side of the reference plate 110, and the shape and specifications of the vertical positioning holes 1103 are the same. Two matching vertical positioning posts are inserted into each of the two vertical positioning holes 1103. The axis of the vertical positioning hole 1103 coincides with the axis of the vertical positioning post, and the shape and specifications of the two vertical positioning posts are the same.

[0049] like Figure 5 The height of the vertical positioning post shown is greater than the height of the reference plate 110. The vertical positioning post includes an embedded section located within the vertical positioning hole 1103 and a protruding section located above the reference plate 110, with the embedded section and the protruding section being an integral structure. The embedded section is cylindrical and coincides with the axis. The depth of the vertical positioning hole 1103 limits the height of the vertical positioning post, facilitating assembly and positioning, and ensuring the height of the protruding section of the vertical positioning post, so that when the cover 200 is placed on the reference plate 110, the lower surface of the cover 200 fits precisely against the upper surface of the reference plate 110. Correspondingly, the inner wall of the vertical positioning hole 1103 of the reference plate 110 matches the shape of the outer wall of the embedded section of the vertical positioning post. In order to keep the two relatively fixed when the vertical positioning post is inserted into the vertical positioning hole 1103 and to prevent deviations in the results due to offset, the outer wall of the embedded section of the vertical positioning post is made to fit tightly with the inner wall of its corresponding vertical positioning hole 1103.

[0050] Furthermore, the mark position 1101 is located at the edge of the reference plate 110 near the free side 1104 for easy observation.

[0051] Furthermore, an inner groove is provided at the marked position 1101. The inner groove is provided at the end of the limiting groove 1102 and extends to the outer surface of the reference plate 110. When the protective cover 200 surrounds the outer surface of the reference plate 110, the groove can be used to observe whether the protective cover 200 is in contact with the outer surface of the reference plate 110.

[0052] Furthermore, such as Figure 4 and Figure 7 As shown, the first positioning structure 130 includes a transverse positioning post, and the limiting block 120 is provided with a transverse positioning post hole 1202, through which the transverse positioning post passes through the transverse positioning post hole 1202 and the protective cover 200.

[0053] Both the horizontal and vertical positioning posts can be made of stainless steel. The limiting block 120 has a horizontal positioning hole, the inner wall of which matches the outer wall shape of the inner section of the horizontal positioning post. To ensure the horizontal positioning post remains relatively fixed when inserted into the horizontal positioning hole and to prevent deviations due to offset, the outer wall of the inner section of the horizontal positioning post is made to fit tightly with the inner wall of the corresponding horizontal positioning hole. The use of horizontal positioning posts allows for quick assembly of the cover 200 and the fixture.

[0054] Furthermore, such as Figure 6 As shown, the limiting block 120 is a cubic metal block.

[0055] Furthermore, the lower surface of the shield 200 on the side opposite to the opening of the shield 200 is attached to the upper surface of the reference plate 110.

[0056] In this application, a reference plate 110 and a limiting block 120 made of AL6061 material can be used.

[0057] The process of using the fixture in this embodiment is as follows:

[0058] 1. Place the reference plate 110 stably on the worktable.

[0059] 2. Fix the limiting block 120 to the reference plate 110 using the second positioning structure 140.

[0060] 3. Place the protective cover 200 stably along the limiting groove 1102 of the reference plate 110.

[0061] 4. Fix the protective cover 200 and the limiting block 120 with the first positioning structure 130.

[0062] 5. Observe whether the features of the protective cover 200 are consistent with the marking position 1101 on the reference plate 110. If they are consistent, it is qualified; otherwise, it is unqualified. Confirm the specific position.

[0063] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.

[0064] For those skilled in the art, various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the protection scope of this invention.
