Description

Technical Field

[0001] This utility model relates to the field of automotive roof processing technology, and more specifically, to an automotive roof detection and positioning device. Background Technology

[0002] The car roof is made of a composite of a base material and a fabric. Generally, after the injection-molded semi-finished base material is processed, a layer of decorative fabric is attached to its lower surface. At both ends of the roof base material and at the sunroof opening, the edges need to be wrapped. That is, the decorative fabric attached to the inner surface of the sunroof frame of the interior roof semi-finished product needs to be flipped from the inner surface of the sunroof frame to the outer surface of the sunroof opening and bonded to the outer surface of the sunroof frame.

[0003] After the car roof is finished, plastic support components are usually installed on the outer perimeter of its back and the outer perimeter of the sunroof opening to increase structural strength. Mushroom-shaped fasteners are also glued to the plastic support components. Mushroom-shaped fasteners are mainly used to connect the entire car roof to the roof mounting bracket by adhesive.

[0004] Currently, after the automotive roof is manufactured, the entire assembly needs to be placed on a specialized testing fixture for dimensional inspection. Only those that pass the inspection can leave the factory. If the assembly is found to have uneven surfaces or does not meet requirements after being installed at the OEM, each component of the assembly needs to be checked individually. Currently, the inspection process requires the design of three positioning fixtures to achieve the positioning of the automotive roof in three different states, and then to inspect the roof's surface in each of these three positioning states. The first test involves placing the positioning block directly on the lower surface of the roof body for inspection, i.e., when no other accessories are installed on the roof body. If the inspection passes without issue, the problem lies with other accessories. The second test involves installing a plastic part on the back of the roof body, with the positioning block supporting and positioning it on the lower surface of the plastic part. If the inspection passes, both the roof body and the plastic part are fine; if it fails, the plastic part is faulty. If the second test passes, a third test is performed. During this test, mushroom-shaped fasteners are attached to the plastic part, and the positioning block directly supports and positions the fasteners. If the test fails, the fasteners are faulty; if it passes, the roof body itself is fine, and the problem may lie with the OEM's body panel work.

[0005] The existing troubleshooting process requires three dedicated positioning fixtures, which not only occupy a lot of space and have high fixture costs, but also require multiple moves and handling of the product during the process, which is not only time-consuming and labor-intensive, but also has low testing efficiency. Summary of the Invention

[0006] The problem solved by this utility model is to overcome at least one defect in the prior art and provide a car roof detection and positioning device that can realize multi-state positioning of the roof by simply replacing the positioning block of the corresponding state, thereby reducing tooling costs and improving detection efficiency.

[0007] To address the aforementioned problems, this utility model provides a vehicle roof detection and positioning device, comprising a base plate. Multiple positioning components are arranged circumferentially along the sunroof opening on the base plate at positions corresponding to the sunroof opening of the vehicle roof. Each positioning component includes a positioning base and multiple positioning blocks. The multiple positioning blocks are detachably connected to the upper end of the positioning base. When different positioning blocks are connected to the positioning base, they are used to support and position the vehicle roof in different states. The base plate also has multiple pressing components corresponding to each positioning base, each pressing component being used to press and limit the upper surface of the vehicle roof.

[0008] Compared with the prior art, the advantages of this utility model's car roof detection and positioning device are: This utility model discloses a car roof inspection and positioning device, which is a dedicated multi-functional positioning fixture. Multiple universal positioning bases are set on a base plate. These bases can be used to install positioning blocks in different states. When the car roof needs to be positioned in different states, only the corresponding positioning block needs to be selected and connected to the positioning base. This eliminates the need to transfer the product to different positioning fixtures as in traditional methods, thus improving positioning efficiency and saving costs. Both the test base and the positioning bases are universal components; only the corresponding positioning blocks need to be replaced, making it very convenient. Furthermore, this structure incorporates multiple pressing components, effectively improving the stability of the car roof after positioning and enhancing inspection accuracy.

[0009] Furthermore, the plurality of positioning blocks are respectively a first positioning block, a second positioning block, and a third positioning block. The upper surface of the first positioning block is a positioning profile that matches the lower surface of the car roof body, and a fixing plate for connecting the first positioning block to the positioning base is connected thereon. The second positioning block includes a horizontal positioning plate for supporting the lower surface of the plastic part of the car roof and a vertical connecting plate for connecting the horizontal positioning plate to the positioning base. The third positioning block is connected to the top of the positioning base and is used to support and limit the lower surface of the mushroom-shaped hook and loop fastener on the car roof.

[0010] As an improvement, the side wall of the positioning base is provided with a horizontally extending threaded hole, and a connecting bolt is installed in the threaded hole. Both the fixing plate and the vertical connecting plate are provided with elongated through holes that extend vertically and are used for the connecting bolt to pass through.

[0011] Furthermore, the press-fit assembly includes a support rod and a pressure plate. The support rod is vertically telescopically connected to the base plate, and one end of the pressure plate is connected to the upper end of the support rod, while the other end is pressed against the upper surface of the car roof.

[0012] In a further improvement, a connecting hole is provided on the substrate, and the lower end of the support rod slides through the connecting hole. A limiting boss is connected to the lower end of the support rod, and an elastic element is provided between the upper end face of the limiting boss and the lower end face of the substrate. A limiting block is provided at the upper end of the substrate corresponding to the connecting hole, and a positioning pin is provided on the outer wall of the upper end of the support rod. In the initial state, under the action of the elastic element, the positioning pin abuts against the upper end face of the limiting block.

[0013] In a further improvement, the elastic element is a cylindrical spring, and the cylindrical spring is fitted onto the outside of the support rod. The upper and lower ends of the cylindrical spring abut against the lower end face of the substrate and the upper end face of the limiting boss, respectively.

[0014] In a further improvement, the limiting block includes a connecting base plate and two limiting plates. The connecting base plate has a clearance hole coaxial with the communicating hole. The two limiting plates are vertically connected to the connecting base plate and symmetrically arranged on both sides of the clearance hole. The positioning pin is horizontally inserted through the support rod and is movably disposed in the limiting channel between the two limiting plates. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] 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.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See appendix Figures 1-9 This utility model provides a vehicle roof inspection and positioning device, which includes a base plate 1. On the base plate 1, a plurality of positioning components are arranged circumferentially along the sunroof opening at a position corresponding to the sunroof opening of the vehicle roof. The base plate 1 is also provided with a plurality of pressing components corresponding to each positioning base 2. Each pressing component is used to press and limit the upper surface of the vehicle roof to achieve stable positioning of the vehicle roof, so as to facilitate the inspection personnel to accurately measure the external dimensions of the product assembly and to identify the problem points of the product assembly.

[0021] During actual product positioning, multiple positioning components are set on the substrate 1. Since the structure of each positioning component is the same, this embodiment will take one of the positioning components as an example for detailed explanation: The positioning assembly includes a positioning base 2 and multiple positioning blocks. The positioning base 2 includes a vertical column, with a horizontal mounting block connected to the lower end of the vertical column. The horizontal mounting block has multiple mounting through holes, each with a connecting screw, used to achieve a stable connection between the positioning base 2 and the base plate 1, facilitating insertion after connection. Furthermore, the multiple positioning blocks can be detachably connected to the upper end of the positioning base 2. That is, when different positioning blocks are connected to the positioning base 2, they are used to support and position the car roof in different states. Simply put, when the car roof needs to be positioned in different states, only the corresponding positioning block needs to be connected to the positioning base 2, eliminating the need to transfer the product to different positioning fixtures as in traditional methods. This improves positioning efficiency and saves costs. The base plate 1 and the positioning base 2 are universal components; only the corresponding positioning blocks need to be replaced, which is very convenient. In this embodiment, in order to further improve the product positioning stability, a plurality of pressing components corresponding to each positioning base 2 are also provided on the substrate 1. Each pressing component is used to press and limit the product to the upper surface of the car roof. The specific structure of the pressing components will be described in detail below.

[0022] In this embodiment, the car roof generally needs to undergo three state transitions during testing. Therefore, the aforementioned multiple positioning blocks are the first positioning block 3, the second positioning block 4, and the third positioning block 5. The upper surface of the first positioning block 3 is a positioning profile that matches the lower surface of the car roof body 16, and a fixing plate 6 for connecting it to the positioning base 2 is connected to the first positioning block 3. That is, when the car roof is positioned in the first state, see Appendix Figure 2 , 3 In positions 4 and 5, the first positioning block 3, consisting of multiple positioning components, is directly supported on the lower surface of the roof body 16. In this state, the dimensions of the car roof are checked to determine if there are any problems with the car roof body 16. The second positioning block 4 includes a horizontal positioning plate 41 for supporting the lower surface of the plastic part 17 of the car roof and a vertical connecting plate 42 for connecting the horizontal positioning plate 41 to the positioning base 2. That is, when the car roof is positioned in the second state, the lower end of the plastic part 17 below the car roof body 16 is supported by the second positioning block 4. In this state, the dimensions of the car roof are checked to determine if there are any problems with the plastic part 17. This second-state positioning is generally performed after the first state has been checked and found to be without problems with the car roof body 16. (See Appendix) Figure 6 , 7The third positioning block 5 is directly connected to the top of the positioning base 2 and is used to support and limit the lower end face of the mushroom-shaped hook-and-loop fastener 18 on the car roof. That is, when the car roof is positioned in the third state, the lower end face of the mushroom-shaped hook-and-loop fastener 18 below the plastic part 17 is supported by the third positioning block 5. In this state, the dimensions of the car roof are checked to determine whether there is a problem with the mushroom-shaped hook-and-loop fastener 18 part. This second state positioning is generally performed after the car roof body 16 and the plastic part 17 have been checked and found to be without problems. See Appendix. Figure 8 , 9 .

[0023] In the above structure, there is no need to improve the entire positioning device. Only by replacing different positioning blocks, the positioning of the car roof in three different states can be achieved, enabling troubleshooting of three different components, effectively improving work efficiency and saving costs.

[0024] More specifically, in this embodiment, a horizontally extending threaded hole is provided on the side wall of the positioning base 2, and a connecting bolt 7 is installed in the threaded hole. Both the fixing plate 6 and the vertical connecting plate 42 have elongated through holes 8 extending vertically for the connecting bolt 7 to pass through. The first positioning block 3 and the second positioning block 4 are detachably connected to the positioning base 2 by the connecting bolt 7, and the vertical position of the first positioning block 3 and the second positioning block 4 can be adjusted by adjusting the position of the connecting bolt 7 in the elongated through hole 8, which is very convenient. Furthermore, the connecting bolt 7 is preferably a manual wing bolt, which can be operated manually without the need for special tools, making it very convenient.

[0025] In this embodiment, multiple press-fitting structures are identical. The following is a detailed description of one of the press-fitting components: See appendix Figure 2 The press-fit assembly includes a support rod 9 and a pressure plate 10. The support rod 9 is vertically telescopically connected to the base plate 1. One end of the pressure plate 10 is connected to the upper end of the support rod 9, and the other end is pressed against the upper surface of the car roof. The pressure plate 10 and the car roof can be pressed and released by adjusting the vertical position of the support rod 9.

[0026] For more details, please see the appendix. Figure 5In this embodiment, a connecting hole 11 is provided on the substrate 1, and the lower end of the support rod 9 slides through the connecting hole 11. The lower end of the support rod 9 is connected to a limiting boss 12. The limiting boss 12 is a circular boss with a diameter larger than that of the support rod 9. An elastic element 13 is provided between the upper end surface of the limiting boss 12 and the lower end surface of the substrate 1. Under the elastic force of the elastic element 13, the support rod 9 always has a downward tendency. That is, in the initial state, the lower end surface of the pressure plate 10 is lower than the upper surface of the car roof. When positioning, the support rod 9 needs to be pulled upward so that the pressure plate 10 is pressed against the upper surface of the car roof. Furthermore, the support rod 9 needs to be rotated here to facilitate the loading and unloading of the car roof without causing interference.

[0027] In addition, in the above structure, a limiting block 14 is provided at the upper end of the substrate 1 corresponding to the position of the connecting hole 11, and a positioning pin 15 is provided on the outer wall of the upper end of the support rod 9. In the initial state, under the action of the elastic element 13, the positioning pin 15 abuts against the upper end surface of the limiting block 14.

[0028] In this embodiment, preferably, the elastic element 13 is a cylindrical spring, and the cylindrical spring is sleeved on the outside of the support rod 9. The upper and lower ends of the cylindrical spring abut against the lower end surface of the substrate 1 and the upper end surface of the limiting boss 12, respectively. See attached drawing. Figure 5 .

[0029] In other embodiments, the elastic element 13 may also be other types of springs, or a rubber bellows structure, configured as an elastic push rod structure.

[0030] See appendix Figure 3 The limiting block 14 includes a connecting base plate 141 and two limiting plates 142. The connecting base plate 141 is fixed on the base plate 1, and a clearance hole coaxial with the connecting hole 11 is provided on the connecting base plate 141. The two limiting plates 142 are vertically connected to the connecting base plate 141 and symmetrically arranged on both sides of the clearance hole. The positioning pin 15 is horizontally inserted through the support rod 9, and the positioning pin 15 is movably disposed in the limiting channel between the two limiting plates 142. In the initial state, under the action of the spring, the positioning pin 15 abuts against and is limited to the upper end face of the connecting base plate 141. In this structure, the limiting block 14 makes the up-and-down movement of the support rod 9 more stable, and under the action of the positioning pin 15, the support rod 9 will not rotate circumferentially, ensuring the stability of the lifting and lowering of the pressure plate 10. When loading and unloading the car roof, in order to avoid interference from the pressure plate 10, the support rod 9 needs to be raised until the positioning pin 15 is disengaged from the limiting channel, after which the support rod 9 can rotate circumferentially.

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.
