Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection tool technology, and more specifically, to a vehicle headlight profiling inspection tool and a split-type inspection tool assembly. Background Technology
[0002] The manufacturing of a car involves four workshops: stamping, welding, painting, and final assembly, as well as an inspection process to ensure the vehicle's quality and safety. The stamping process uses stamping equipment and molds to press automotive-grade steel sheets into various shapes and structures required for the car body, such as front fenders and side panels. The welding process involves assembling various body parts into a white body (unpainted) using welding robots or manually. The painting process is to prevent rust. The final assembly process assembles the body, chassis, interior, and exterior components into a complete vehicle. Notably, lights, as exterior components, are installed during the final assembly stage, and the fit clearances can only be measured after the lights are installed.
[0003] If there is an assembly gap problem between the headlights and the body, the vehicle body can only be returned to the welding workshop or the final assembly workshop for rework to make the fit between the two meet the design requirements. Therefore, headlight fit gap problems are always discovered in the final assembly workshop, which results in high repair costs and long repair times. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing headlight and body assembly gap issues, which often occur after production has entered the final assembly workshop, resulting in high rework costs. This invention provides a headlight profiling fixture and a split-type fixture assembly. This invention can predict potential fit problems after headlight exterior parts are installed, even before the welding process, and can proactively address these issues, improving quality control efficiency.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A vehicle headlight profiling fixture includes a profiling block replicated 1:1 according to the headlight structure, a positioning component disposed on the profiling block for positioning onto the vehicle body, and a fixing component disposed on the profiling block for fixing the profiling block onto the vehicle body. The profiling block is provided with a plurality of measuring parts at the junction with the vehicle body, and the surface difference between the measuring parts and the adjacent vehicle body is 0 after installation.
[0007] This utility model's profiling block is a 1:1 replica of the shape, mounting points, and installation position of a vehicle headlight exterior component. Unlike the actual headlight body, this utility model not only simulates the headlight itself, allowing for installation on the vehicle body in the welding workshop, but also enables direct measurement of the fit clearance between the headlight and the vehicle body. Because headlights have many shaped surfaces, the sheet metal joints between the headlight and the vehicle body are often not on the same plane after installation, making direct measurement impossible. Therefore, this utility model's profiling block not only simulates the headlight's shape but also, through the structural design of the measuring section, aligns the measuring area with the vehicle body. By filling in the surface difference, when the surface difference between the measuring part and the adjacent body is 0, the adjacent areas of different planes on both sides of the gap after installing the molding block become the same plane. This allows for manual on-site inspection of the gap using feeler gauges and step gauges, enabling rapid on-site measurement with low cost and fast inspection speed. This invention can be used for quality analysis, allowing for early identification of potential fit problems after the installation of the headlight trim before the welding process, and enabling proactive solutions to improve quality control efficiency. In addition, this invention can be used as a standard part to calculate the contribution of the body and headlight trim to the defect during the analysis process.
[0008] Furthermore, the measuring unit includes a filler block, the thickness of which is the height difference between the adjacent surfaces of the headlight and the body. When a surface difference exists at the measuring location, the measuring unit is a filler block designed separately from the vehicle body styling design. The thickness of the filler block is the height difference between the adjacent surfaces of the headlight and the body, locally filling in the surface difference at the measuring location, thus enabling rapid measurement. The design of the filler block can rely on the model data from the headlight styling design, calculating the required filling position and height with the vehicle body styling design data, and integrally molding it during the production of the model block of this utility model.
[0009] Furthermore, the measuring unit can also be equipped with measuring indicator points. Setting measuring indicator points can guide operators to quickly locate the measuring position and improve the measuring speed.
[0010] Furthermore, the profiling block is equipped with several handles for easy gripping. These handles facilitate handling by operators, improving the ease of installation and disassembly.
[0011] Furthermore, the copy block is made of aluminum. The aluminum copy block allows for weight reduction, improving the overall lightweight effect of the inspection tool.
[0012] Furthermore, the template block is also provided with perforated slots. The use of aluminum template blocks and the provision of perforated slots on the template blocks can greatly improve the lightweight effect of the gauge and reduce the difficulty of operation for operators during the measurement process.
[0013] Furthermore, the positioning component is a positioning pin, which is located at the mounting point of the copied vehicle headlight design. The positioning pin design utilizes the mounting point position designed during the installation of the vehicle headlight itself, thus also having pre-drilled mounting holes on the vehicle body, which can reduce production costs and simplify the structural design of this utility model.
[0014] Furthermore, the number of locating pins is at least two. At least two locating pins ensure that the molding block does not rotate or shift, and allow for quick positioning in conjunction with the pre-drilled holes, making installation simple and convenient.
[0015] Furthermore, the locating pins are not located at the same horizontal level. When the locating pins are not located at the same horizontal level, they can form positioning in two directions: X-axis positioning and Z-axis positioning, forming at least one set of diagonal positioning patterns, which has a better positioning effect.
[0016] Furthermore, the fastener is a bolt, located at the mounting point of the replicated headlight design. The fastener design utilizes the mounting point position designed during the headlight's installation, and there are also pre-drilled mounting holes on the vehicle body. This not only simulates the locking effect that might occur after the bolts are tightened during actual headlight installation, but also simulates potential locking fit issues that might arise after applying the same tightening force.
[0017] Furthermore, the sum of the number of fastening bolts and the number of locating pins equals the sum of the mounting points of the replicated car headlight design. By using all the mounting points of the replicated car headlight design, especially when only two locating pins are used and the rest are fastening bolts, the same tightening force can be applied to simulate the locking effect of the car headlight during actual installation to the greatest extent. This allows for better identification of any fitting problems that may occur after the car headlight and body are installed.
[0018] This utility model also provides a split-type gauge assembly, including at least two as described above headlight profiling gauges. Each of the adjacent headlight profiling gauges is provided with a measuring part, and the surface difference between the measuring parts of the two adjacent headlight profiling gauges after installation on the vehicle body is 0.
[0019] It should be noted that as vehicle designs become increasingly diverse, headlight designs also vary, with many split headlight designs emerging, such as separate headlights and taillights. To accommodate these split headlights, they sometimes overlap. To address this diversity, measuring sections are installed at the junctions of adjacent headlight profiling fixtures. The surface difference between the measuring sections of adjacent headlight profiling fixtures after vehicle body assembly is zero. This allows for the measurement of the fit clearance between split headlights in the welding workshop, providing a more comprehensive inspection.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] (1) The model block of this utility model is a 1:1 replica of the shape, installation point and installation position of the exterior trim of the car headlight. The difference between it and the actual headlight body is that this utility model can not only simulate the headlight body and install it with the car body in the welding workshop, but also directly measure the gap between it and the car body after installation. Since the headlight has many shaped surfaces, the sheet metal splice at the junction of the headlight and the car body is often not on the same plane after the headlight is installed, and it is impossible to measure directly. Therefore, the model block of this utility model not only simulates the shape of the headlight, but also makes up the surface difference between the measuring part and the car body through the structural design of the measuring part after installation. When the surface difference between the measuring part and the adjacent car body is 0, the junction of the different planes on both sides of the gap after the model block is installed becomes the same plane. In this way, the gap can be detected manually on the spot using feeler gauges and step gauges, which is quick and cost-effective.
[0022] (2) This utility model can be used for quality analysis. Before the welding process is completed, it can predict what kind of matching problems will exist after the installation of the vehicle headlight exterior parts, and can take countermeasures in advance to improve the efficiency of quality cultivation. In addition, this utility model can be used as a standard part to calculate the contribution of the vehicle body and vehicle headlight exterior parts to the defect during the analysis process.

[0033] Example 1
[0034] like Figures 1 to 4 The first embodiment of this utility model is shown below. This embodiment takes the A-lamp 100 unit in the taillight of a certain car model as an example:
[0035] like Figure 1 and Figure 2 As shown, a vehicle headlight profiling fixture includes a profiling block 1 replicated 1:1 according to the vehicle headlight structure, a positioning member 2 disposed on the profiling block 1 for positioning on the vehicle body, and a fixing member 3 disposed on the profiling block 1 for fixing the profiling block 1 to the vehicle body. A plurality of measuring parts 11 are provided at the junction of the profiling block 1 and the vehicle body. After installation with the vehicle body, the surface difference between the measuring parts 11 and the adjacent vehicle body is 0.
[0036] like Figure 4As shown, the profiling block 1 in this embodiment is a 1:1 replica of the shape, mounting point, and mounting position of the A-lamp 100 single-unit taillight exterior trim of a certain car model. The difference from the actual lamp body is that this embodiment can not only simulate the lamp body and install it to the vehicle body in the welding workshop, but also directly measure its fit clearance with the body after installation. Because the lamp has many shaped surfaces, the sheet metal joints between the lamp and the vehicle body are often not on the same plane after installation, making direct measurement impossible. Therefore, the profiling block 1 in this embodiment not only simulates the lamp shape but also, through the structural design of the measuring unit 11, can... The surface difference between the measuring unit 11 and the vehicle body is compensated, so that when the surface difference between the measuring unit 11 and the adjacent vehicle body is 0, the adjacent areas of different planes on both sides of the gap after the installation of the contour block 1 become the same plane. This allows for manual on-site inspection of the gap using feeler gauges and step gauges, enabling rapid on-site measurement with low cost and fast inspection speed. This embodiment can be used for quality analysis, allowing for early identification of potential fit problems after the installation of the headlight trim before the welding process, and enabling proactive solutions to improve quality development efficiency. In addition, this embodiment can be used as a standard part to calculate the contribution of the vehicle body and headlight trim to the defect during the analysis process.
[0037] like Figure 2 As shown, the measuring unit 11 includes a filler block, the thickness of which is the height difference between the adjacent surfaces of the headlight and the body. When there is a surface difference at the measuring unit 11, the measuring unit 11 is a filler block designed separately from the vehicle body styling design. The thickness of the filler block is the height difference between the adjacent surfaces of the headlight and the body. By partially filling the surface difference at the measuring unit 11, rapid measurement can be achieved. The design of the filler block can rely on the model data from the headlight styling design, calculate it with the vehicle body styling design data to obtain the position and height that need to be filled, and integrally molded during the production of the model block 1 of this utility model.
[0038] In this embodiment, the measuring unit 11 may also be provided with measuring indicator points. Setting measuring indicator points can guide the operator to quickly locate the measuring position and improve the measuring speed.
[0039] like Figure 2 As shown, the molding block 1 is also equipped with several handles 4 for easy gripping. The handles 4 make it convenient for operators to pick up and remove the blocks, improving the ease of installation and disassembly.
[0040] In this embodiment, the molding block 1 is an aluminum molding block 1.
[0041] like Figure 2 As shown, the template block also has a hollowed-out slot 12. Using an aluminum template block and having a hollowed-out slot 12 on it can greatly improve the lightweight effect of the gauge and reduce the difficulty of operation for the operator during the measurement process.
[0042] Example 2
[0043] This embodiment is similar to Embodiment 1, except that in this embodiment...
[0044] like Figure 3 As shown, positioning component 2 is a positioning pin, located at the mounting point of the copied vehicle headlight design. The positioning pin design utilizes the mounting point position designed during the installation of the vehicle headlight itself, thus also having pre-drilled mounting holes on the vehicle body, which reduces production costs and simplifies the structural design of this utility model.
[0045] like Figure 3 As shown, this embodiment uses two locating pins. At least two locating pins ensure that the molding block 1 does not rotate or shift, and it can be quickly positioned using the pre-drilled holes, making installation simple and convenient.
[0046] like Figure 3 As shown, the locating pins in this embodiment are not located at the same horizontal height. When the locating pins are not located at the same horizontal height, they can form positioning in two directions: X-axis positioning and Z-axis positioning, forming at least one set of diagonal positioning patterns, which has a better positioning effect.
[0047] In this embodiment, the fixing component 3 is a fastening bolt, and the fastening bolt is located at the mounting point of the replicated vehicle headlight design. The design of the fixing component 3 can utilize the mounting point designed during the installation of the vehicle headlight itself, so there are also pre-drilled mounting holes on the vehicle body. This not only simulates the locking effect that may occur after the bolt is tightened during actual installation of the vehicle headlight, but also simulates the locking fit problems that may occur after the same tightening force is applied.
[0048] In this embodiment, the sum of the number of fastening bolts and the number of locating pins is equal to the sum of the mounting points of the replicated vehicle headlight design. By using all the mounting points of the replicated vehicle headlight design, especially when only two locating pins are used and the rest are fastening bolts, the same locking force can be applied to simulate the locking effect of the vehicle headlight during actual installation to the greatest extent. This allows for better identification of any fitting problems that may occur after the vehicle headlight and vehicle body are installed.
[0049] The other structures and principles of this embodiment are the same as those of Embodiment 1.
[0050] Example 3
[0051] like Figure 5 and Figure 6As shown, this utility model also provides a split-type fixture assembly, including at least two vehicle headlight profiling fixtures as described above. Taking a split-type taillight of a certain vehicle model as an example, it includes A light 100, B light 200 and C light 300. A light 100 integrates brake light, fog light and turn signal. B light and C light are split light bodies for styling purposes. Specifically, B light 200 is a through light and C light 300 is a reflector. The adjacent joint of two adjacent vehicle headlight profiling fixtures is provided with a measuring part 11. The surface difference between the measuring parts 11 of the two adjacent vehicle headlight profiling fixtures after installation on the vehicle body is 0.
[0052] It should be noted that as vehicle designs become increasingly diverse, headlight designs also vary, with many split headlight designs emerging, such as split headlights and taillights. To accommodate these split headlights, they sometimes overlap. To address these diverse headlight designs, measuring sections 11 are provided at the junction of two adjacent headlight profiling fixtures. The surface difference between the measuring sections 11 of the two adjacent headlight profiling fixtures after vehicle body assembly is zero. This allows for the measurement of the fit clearance between split headlights in the welding workshop, resulting in a more comprehensive inspection.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
