Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a tool for inspecting a fuel filler neck assembly that covers the fuel tank filling port. Background Technology

[0002] The fuel filler neck assembly is a crucial component of a car's body panels, primarily used to conceal and protect the fuel tank filler neck. Its performance and quality not only affect the overall visual integrity and aesthetics of the vehicle but also directly impact the user experience and driving safety. In terms of manufacturing quality, the assembly's dimensional accuracy, its matching clearance with surrounding body panels, the smoothness of its opening and closing process, and the reliability of its locking mechanism are all key indicators of its quality. If the dimensions are out of tolerance or the matching is poor, it will disrupt the overall smoothness of the vehicle's profile; if the opening and closing is choppy or the locking is not secure, it may cause abnormal noises, vibrations, or even fuel leaks during vehicle operation, posing safety hazards.

[0003] In the current mass production model, most vehicle manufacturers or parts suppliers still use traditional manual inspection methods. Operators need to use special measuring tools such as calipers, gap gauges, and surface difference gauges to measure the key dimensions, gaps, and surface differences of the fuel filler valve assembly one by one. At the same time, they also need to simulate daily use by repeatedly opening and closing it manually, and judge whether its movement is smooth and whether the locking is in place by feel and experience.

[0004] This testing method has obvious shortcomings: First, the testing efficiency is low, making it difficult to match the production rhythm of automated production lines and easily creating production bottlenecks; second, the measurement results are greatly affected by human factors such as the operator's skill level, fatigue level, and subjective judgment, resulting in poor data consistency and difficulty in guaranteeing accuracy; third, manual testing lacks the ability to quickly and quantitatively assess the overall compatibility of parts with the vehicle body, and cannot anticipate matching problems after assembly in advance during the testing process. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tooling for a fuel filler door assembly for shielding the fuel tank filler neck, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a gauge for a fuel filler door assembly used to cover the fuel tank filling port, comprising: a base, a positioning component, a contour detection component, and an opening / closing detection component. The positioning component is fixedly connected to the top of the base and is used to position and fix the fuel filler door assembly. The contour detection component includes several contour blocks that are adapted to the preset outer contour of the fuel filler door assembly and are arranged around the outside of the positioning component. The opening / closing detection component includes a drive component, a connecting arm, and a simulated latch. The drive component is fixedly installed at the top of the base, one end of the connecting arm is connected to the output end of the drive component, and the simulated latch is installed at the other end of the connecting arm. The simulated latch is adapted to the locking structure of the fuel filler door assembly and is used to simulate the opening, closing, and locking actions of the fuel filler door.

[0008] Furthermore, the positioning component includes several positioning pins and support blocks. The positioning pins are adapted to the mounting holes of the fuel filler door assembly, and the top surface of the support block is fitted and supported against the back of the fuel filler door assembly.

[0009] Furthermore, a contour detector is provided on the surface of the contour block, and the contour detector is detachably connected to the contour block.

[0010] Furthermore, the driving component is a cylinder or an electric push rod, the connecting arm is a telescopic structure, and the connecting arm is equipped with a length adjustment and locking knob.

[0011] Furthermore, a pressure sensor is provided at the end of the simulated latch, and the pressure sensor is electrically connected to an external display terminal.

[0012] Furthermore, it also includes a clamping assembly, which includes a bracket, a clamping cylinder, and a clamping head. The bracket is fixedly connected to the top of the base, the clamping cylinder is installed on the top of the bracket, and the clamping head is connected to the output end of the clamping cylinder. The clamping head and the positioning assembly cooperate with each other to clamp and fix the fuel filler valve assembly.

[0013] Furthermore, handles are fixedly connected to both sides of the top of the base, and support feet are threaded to the four corners of the bottom of the base. The support feet are used for leveling the base.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By integrating positioning, contour detection, and opening / closing locking functions into one unit, it achieves rapid and synchronous detection of the fuel filler door assembly's external dimensions, matching clearance, opening / closing smoothness, and locking reliability, significantly improving detection efficiency. It can match the production rhythm of modern automated production lines and effectively solves the problem of low efficiency in traditional manual item-by-item inspection;

[0016] 2. By setting up a contour detector and a pressure sensor, the traditional judgment of gap, surface difference and locking force, which relies on touch and experience, is transformed into objective and quantitative electrical signal data output. This effectively avoids measurement errors and data inconsistencies caused by human factors, and greatly improves the accuracy and reliability of the test results.

[0017] 3. The opening and closing detection component, through the drive component and the simulated latch, can accurately and repeatably simulate the actual opening, closing and locking actions of the fuel filler door assembly. Combined with the contour detection component, it can detect potential matching problems between the parts and the vehicle body in advance during the inspection stage, realizing a rapid and quantitative assessment of the parts' compatibility and improving product quality from the source.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1:

[0028] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses a gauge for a fuel filler door assembly used to cover the fuel tank filling port. The gauge includes: a base 1, a positioning component 2, a contour detection component 3, and an opening / closing detection component 4. The positioning component 2 is fixedly connected to the top of the base 1 and is used to position and fix the fuel filler door assembly. The contour detection component 3 includes several contour blocks 301, which are adapted to the preset outer contour of the fuel filler door assembly. The contour blocks 301 surround the outside of the positioning component 2. The opening / closing detection component 4 includes a drive component 401, a connecting arm 402, and a simulated latch 403. The drive component 401 is fixedly installed on the top of the base 1. One end of the connecting arm 402 is connected to the output end of the drive component 401. The simulated latch 403 is installed on the other end of the connecting arm 402 and is adapted to the locking structure of the fuel filler door assembly. The simulated latch 403 is used to simulate the opening, closing, and locking actions of the fuel filler door.

[0029] By integrating positioning, contour detection, and opening / closing locking functions, the system enables rapid and synchronous detection of the fuel filler door assembly's external dimensions, matching gaps, opening / closing smoothness, and locking reliability. This significantly improves detection efficiency, matches the production rhythm of modern automated production lines, and effectively solves the problem of low efficiency in traditional manual item-by-item inspection.

[0030] Example 2:

[0031] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0032] The positioning component 2 includes several positioning pins 201 and support blocks 202. The positioning pins 201 are adapted to the mounting holes of the fuel filler door assembly. The top surface of the support block 202 fits against the back of the fuel filler door assembly for support. A contour detector 302 is provided on the surface of the contour block 301. The contour detector 302 is detachably connected to the contour block 301.

[0033] The driving component 401 is a cylinder or an electric push rod, the connecting arm 402 is a telescopic structure, the connecting arm 402 is provided with a length adjustment locking knob 405, the end of the simulated lock 403 is provided with a pressure sensor 404, and the pressure sensor 404 is electrically connected to an external display terminal.

[0034] It also includes a clamping assembly 5, which includes a bracket 501, a clamping cylinder 502, and a clamping head 503. The bracket 501 is fixedly connected to the top of the base 1, the clamping cylinder 502 is installed on the top of the bracket 501, and the clamping head 503 is connected to the output end of the clamping cylinder 502. The clamping head 503 and the positioning assembly 2 cooperate to clamp and fix the oil filling valve assembly. Handles 101 are fixedly connected to both sides of the top of the base 1, and support feet 102 are threadedly connected to the four corners of the bottom of the base 1. The support feet 102 are used for the horizontal adjustment of the base 1.

[0035] By setting up a contour detector 302 and a pressure sensor 404, the traditional judgment of gaps, surface differences, and locking forces, which rely on touch and experience, is transformed into objective and quantitative electrical signal data output. This effectively avoids measurement errors and data inconsistencies caused by human factors, and greatly improves the accuracy and reliability of the test results. The opening and closing detection component 4, through the drive component 401 and the simulated latch 403, can accurately and repeatably simulate the actual opening, closing, and locking actions of the fuel filler door assembly. Combined with the contour detection component 3, it can detect potential matching problems between parts and the vehicle body in advance during the inspection stage, realizing a rapid and quantitative assessment of part compatibility and improving product quality from the source.

[0036] The remaining structure is the same as that in Example 1.

[0037] The workflow of this utility model is as follows:

[0038] First, the fuel filler door assembly to be tested is placed on the positioning component 2. The positioning pin 201 is engaged with the mounting hole of the fuel filler door assembly, and the support block 202 supports the back of the assembly to achieve precise positioning. Then, the clamping component 5 is activated, and the clamping cylinder 502 drives the pressure head 503 to press down, working together with the positioning component 2 to clamp and fix the fuel filler door assembly.

[0039] Secondly, the contour detection component 3 starts working. The operator observes the matching of the contour block 301 with the outer contour of the fuel filler door assembly, and combines the detection data of the contour detector 302 to quickly determine whether the outer dimensions of the assembly, the matching gap with the surrounding body sheet metal, and the surface difference meet the preset standards.

[0040] Finally, the opening and closing detection component 4 is activated. The drive component 401 drives the simulated latch 403 through the connecting arm 402 to simulate the opening, closing and locking actions of the refueling door. The locking force is monitored in real time by the pressure sensor 404 and transmitted to the external display terminal. The operator comprehensively evaluates the opening and closing performance and locking reliability of the assembly based on the smoothness of the opening and closing process and the locking force data. After the test is completed, the clamping component 5 is released, the workpiece is removed, and the qualified judgment and sorting are carried out according to the test results.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
