Description

Technical Field

[0001] This utility model relates to the field of automotive roof processing technology, and more specifically, to a device for measuring the edge gap of an automotive roof. Background Technology

[0002] The car headliner is made of a composite material of a base material and a fabric. Generally, after the injection-molded semi-finished base material is processed, a layer of decorative fabric is glued to its lower surface. Edge binding is required at both ends of the headliner base material and at the sunroof opening. Specifically, the decorative fabric glued to the inner surface of the sunroof frame of the semi-finished headliner needs to be flipped from the inner surface of the sunroof frame to the outer surface of the sunroof opening and bonded to it. The headliner fabric edge binding usually involves first spraying adhesive, and then flipping and pressing the edges together for bonding.

[0003] After the car roof is finished with edging, its overall dimensions will change. Whether the finished roof edging dimensions meet the requirements needs to be reflected by inspecting the overall dimensions of the finished product. However, the car roof has a large external dimension, making it difficult to inspect its overall dimensions. In existing technology, the car roof is positioned horizontally on a testing platform, and a gap will form between its circumferential outer edge and the surface of the testing platform. Since the roof is integrally curved, as the radial dimension increases, the gap between its lower edge surface and the testing platform will decrease. By measuring the gap between the lower edge surface of the roof and the testing platform, the external dimensions of the roof can be indirectly fed back, thereby determining whether the product's external dimensions are qualified.

[0004] In existing technologies, inspectors manually insert feeler gauges into the gaps one by one for testing and then manually read the readings. To improve the accuracy of the test data, the testing gaps are usually set relatively small. However, small gaps can affect the operation of the feeler gauges and reduce testing efficiency. In short, existing testing methods have many inconveniences and shortcomings. Therefore, it is essential to develop a specialized tooling that facilitates testing, reduces manual operation time, and improves efficiency. Utility Model Content

[0005] The problem solved by this utility model is to overcome at least one defect in the prior art and provide a vehicle roof edge gap measuring device that can efficiently, quickly and accurately measure the gap between the lower end face of the outer edge of the roof and the detection platform, thereby quickly determining whether the product size meets the requirements and improving detection efficiency.

[0006] To address the aforementioned problems, this utility model provides a vehicle roof edge gap measuring device, comprising multiple detection inserts for mounting on a test bench surface. Each detection insert has a mounting base on its outer wall, and each mounting base is connected to a dial indicator. The free end of the dial indicator's measuring rod is connected to a measuring scale. The multiple measuring scales are used to extend between the edge of the vehicle roof and the upper surface of each detection insert, and each measuring scale can move synchronously with the axial movement of the measuring rod to achieve gap detection between the outer edge of the vehicle roof and the multiple detection inserts.

[0007] Compared with the prior art, the advantages of this utility model's automobile roof edge gap measuring device are:

[0008] This utility model discloses a dedicated gap measuring device for automotive roof edges. It utilizes a test bench with multiple detection inserts and a positioning mechanism. When the automotive roof is placed and positioned on the positioning mechanism, a corresponding gap is formed between the lower surface of the circumferential edge of the automotive roof and the upper surfaces of the multiple detection inserts. By operating the measuring rulers on the mounting base—that is, by extending multiple measuring rulers into the gap between the edge of the automotive roof and the upper surfaces of each detection insert—one end of the measuring ruler is connected to the outer end face of the measuring rod of the dial indicator via screws. The measuring rulers extend and retract with the measuring rod, meaning the movement of the measuring rulers during measurement is synchronously fed back to the internal detection element of the dial indicator via the measuring rod, and the measurement data is displayed on the dial. This allows for rapid detection of the gap between the outer edge of the automotive roof and the multiple detection inserts, and comparison with the designed standard gap (the gap between the outer edge of a qualified product sample positioned on the test bench and the multiple detection inserts is used as the standard gap) to determine whether the product dimensions meet the design requirements.

[0009] As an improvement, a support frame is detachably connected to the mounting base, and the support frame is used for pre-installation on the back of the dial indicator, and the support frame is provided with a guide groove for limiting the movement direction of the measuring scale.

[0010] In a further improvement, a positioning rod is provided on the outer wall of the mounting base, and a positioning hole is provided on the support frame for the positioning rod to be inserted and fitted; a positioning block is also provided on the support frame, and a positioning groove is provided on the positioning block, and the guide sleeve on the outside of the measuring rod is snapped and positioned in the positioning groove.

[0011] In a further improvement, a connecting block is connected to the back of the dial indicator, and a through-groove is provided on the connecting block. The side of the support frame away from the mounting base fits into the through-groove. A threaded hole is provided at the bottom of the through-groove, and a connecting screw is passed through the support frame and connected to the threaded hole.

[0012] In a further improvement, the free end of the measuring rod is connected to a horizontal connector, and the end of the horizontal connector away from the measuring rod is provided with a vertical connector perpendicular to it. The measuring ruler is connected to the vertical connector and is parallel to the horizontal connector. The vertical connector is slidably fitted in the guide groove.

[0013] In a further improvement, the horizontal connector, vertical connector, and measuring ruler are integrated into a single structure. This integrated design facilitates manufacturing and reduces cost.

[0014] In a further improvement, a reference element is provided on the side of the support frame near the mounting base and opposite to the measuring ruler. The reference element is used to adjust the initial position of the measuring ruler. Attached Figure Description

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See appendix Figures 1-5 This utility model provides a device for measuring the edge gap of a car roof, which includes a test platform (not shown in the figure), a positioning mechanism (not shown in the figure) for positioning the car roof on the test platform, and multiple detection inserts 1 distributed circumferentially on the outer periphery of the positioning mechanism on the test platform. When the car roof is placed and positioned on the positioning mechanism, a corresponding gap is formed between the lower surface of the circumferential edge of the car roof and the upper surface of the multiple detection inserts 1.

[0027] Additionally, each detection insert 1 has a mounting base 2 on its outer wall, and a dial indicator 3 is connected to each mounting base 2. The free end of the measuring rod of the dial indicator 3 is connected to a measuring scale 4. Multiple measuring scales 4 are used to extend between the edge of the car roof and the upper surface of each detection insert 1, and each measuring scale 4 can move synchronously with the axial movement of the measuring rod to detect the gap between the outer edge of the car roof and the multiple detection inserts 1. In this structure, the dial indicator 3 is a conventional structure, while the measuring scale 4 is a custom-made part based on the dial indicator 3. One end of the measuring scale 4 is connected to the outer end face of the measuring rod of the dial indicator 3 by a screw. The measuring scale 4 can extend and retract with the extension and retraction of the measuring rod, meaning that the movement stroke of the measuring scale 4 during measurement can be synchronously fed back to the internal detection element of the dial indicator through the measuring rod, and the measurement data is displayed on the dial.

[0028] In this embodiment, multiple dial gauges 3 are used in conjunction with corresponding measuring rulers 4 to measure the gap between the lower end of the outer circumferential edge of the car roof and the detection insert 1 after the car roof is positioned, thereby indirectly determining whether the outer dimensions of the car roof edge after edging meet the requirements.

[0029] In this embodiment, the measurement units connected to the multiple detection inserts 1 and the dial indicator 3 all have the same structure. The following description will take the connection structure of one of the detection inserts 1 and the dial indicator 3 as an example for further explanation:

[0030] See appendix Figure 4 , 5 An installation groove is provided on the outside of the insert, and the upper part of the installation groove is open. The mounting base 2 is fitted into the installation groove. A support frame 5 is detachably connected to the mounting base 2. The support frame 5 is used for pre-installation on the back of the dial indicator 3. The support frame 5 is provided with a guide groove 6 for limiting the movement direction of the measuring ruler 4.

[0031] More specifically, in the above structure, two positioning rods 7 are provided on the outer wall of the mounting base 2. The outer ends of the two positioning rods 7 are provided with tapered guides. The support frame 5 is provided with positioning holes 8 for the two positioning rods 7 to be inserted and fitted. The support frame 5 and the mounting base 2 are detachably connected by a plug-in quick-installation structure. Furthermore, the support frame 5 is also provided with corresponding positioning blocks 9. The positioning blocks 9 are provided with positioning grooves 10. When the dial indicator 3 is pre-installed with the support frame 5, the guide sleeve 11 on the outer side of the measuring rod of the dial indicator 3 is snapped and positioned in the positioning groove 10, so that the position of the dial indicator 3 will not easily deviate after installation, thus ensuring measurement accuracy.

[0032] In addition, in this embodiment, a connecting block 12 is connected to the back of the dial indicator 3. The connecting block 12 has a through-groove accommodating groove 13. The side of the support frame 5 away from the mounting base 2 fits into the accommodating groove 13. A threaded hole is provided at the bottom of the accommodating groove 13, and a connecting screw passes through the support frame 5 and is connected to the threaded hole. In this structure, when the support frame 5 is connected to the dial indicator 3, the position is further limited by the accommodating groove 13, ensuring the stability of the dial indicator 3 during measurement, and thus ensuring measurement accuracy.

[0033] In the above structure, a horizontal connector 14 is connected to the free end of the measuring rod. A vertical connector 15, perpendicular to the end of the horizontal connector 14 away from the measuring rod, is provided. The measuring ruler 4 is connected to the vertical connector 15 and is parallel to the horizontal connector 14. The vertical connector 15 is slidably fitted within the guide groove 6. Preferably, the horizontal connector 14, the vertical connector 15, and the measuring ruler 4 are an integral structure; wherein the measuring ruler 4 is a horizontal strip structure.

[0034] Furthermore, in this embodiment, see Appendix Figure 4 , 5 To further improve detection efficiency, a reference element 16 is provided on the support frame 5, near the mounting base 2 and opposite to the measuring scale 4. The reference element 16 is used to adjust the initial position of the measuring scale 4. (See Appendix for further details.) Figure 6When adjusting the measurement reference, each car roof needs to be equipped with a special reference block 17 for adjustment. A standard slot 18 is opened on the reference block 17. The support frame 5 is installed on the reference block 17 according to the set position, ensuring that the reference part 16 abuts against the inner wall of one side of the standard slot 18. Then, the position of the measuring ruler 4 is adjusted. When the side of the measuring ruler 4 away from the reference part 16 abuts against the inner wall of the other side of the standard slot 18, the position of the measuring rod is the zero reference position. Therefore, in actual measurement operations, as long as the mounting base 2 is fixed in the set position and the distance between the mounting base 2 and the upper surface of the detection insert 1 is the same as the width of the standard slot 18, a value will be displayed when the measuring ruler 4 is placed with the side away from the reference part 16 in contact with the lower surface of the edge of the car roof. Depending on the size of the measurement gap, the pointer of the dial indicator 3 may deflect in the positive direction or in the negative direction. As long as the deviation value is within the design tolerance range, it can be determined that the size of the car roof after edging is qualified. If it exceeds the positive tolerance or the negative tolerance, it means that the size of the car roof after edging is too small or too large, does not meet the design standard, and needs to be reworked.

[0035] In embodiments of this utility model, unless otherwise explicitly specified and limited, the "upper end" and "lower end" of the first feature and the second feature can refer to direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Furthermore, the "lower end" and "lower side" of the first feature and the second feature can refer to the first feature being directly below or diagonally below the second feature, or simply indicating that the horizontal height of the first feature is less than that of the second feature. Additionally, terms such as "upper," "lower," "both sides," and "both ends," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation of this utility model.

[0036] In the description of this utility model, the reference to terms such as "this embodiment," "some embodiments," etc., indicates that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
