Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a fuel filler cap bend handle inspection tool for opening and closing fuel filler caps. Background Technology

[0002] In the manufacturing and final assembly of automobile bodies, the fuel filler neck is an important aesthetic and functional component of the vehicle's side panel. Its assembly quality directly affects the vehicle's airtightness, aesthetics, and user experience. To ensure that the fuel filler neck smoothly matches the vehicle's curved surface, opens and closes smoothly without abnormal noise after assembly, a series of functional tests are required at the end of the production line or during quality inspection. The most critical test involves simulating human hand operation of the handle to examine its operating force, rebound force, play, and the presence of any jamming or other issues.

[0003] Currently, the conventional practice on the production line mainly relies on operators to manually inspect the refueling valve handle. However, individual differences among operators (such as strength, feel, and fatigue level) can lead to variations in the force applied to the handle, making it impossible to form a stable and quantifiable evaluation standard. This method largely depends on the operator's personal experience and subjective feelings, and the inspection results are prone to misjudgment or omission. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a refueling door bend handle gauge for opening and closing the refueling port cap, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses a refueling valve handle gauge for opening and closing the refueling cap, comprising:

[0030] The base 1 has two symmetrically distributed handles 4 fixedly connected to its top to facilitate the handling and movement of the entire inspection fixture;

[0031] The detection seat 3 is located above the base 1. The detection seat 3 has a detection groove 37 for detecting the bent handle on its outer side. The detection groove 37 is equipped with a detector 38. The detector 38 is equipped with a detection rod 39 on its outer side. The detection seat 3 has a lower limit rod 34 on its outer side. The detection seat 3 is fixedly connected to an electric push rod 31 on its outer side. The telescopic end of the electric push rod 31 is fixedly connected to an upper limit rod 32.

[0032] Specifically, the base 1 has four rectangular adjustment feet 5 at its bottom, which are used to adjust the level of the base 1 to ensure the accuracy of the test.

[0033] Specifically, the right side of the test seat 3 has a notch 36 for the rotation of the handle, which facilitates the smooth entry of the oil filling valve handle into the test position.

[0034] Specifically, a connecting block 33 is fixedly connected to the outside of the detection seat 3, and a lower limit rod 34 is fixedly connected to the top of the connecting block 33 to ensure that the position of the lower limit rod 34 is fixed and to provide a stable lower support point for the bent handle.

[0035] Specifically, the inner wall of the detection groove 37 is provided with a groove 35, and the detector 38 is installed on the inner wall of the groove 35. The detector 38 can be a displacement sensor or a photoelectric sensor, etc., used to detect whether the bent handle has reached the predetermined position during the flipping process. The detection rod 39 is used to contact the limiting hole on the bent handle to determine its position accuracy.

[0036] In this embodiment, the detector 38 can be a high-precision micro switch or a laser rangefinder. The end of the detection rod 39 can be equipped with a roller or contact head to reduce friction with the bent handle and ensure smooth detection. The electric push rod 31 has its stroke precisely controlled by a control system such as a PLC, ensuring that the upper limit rod 32 and lower limit rod 34 can accurately clamp the hinge hole of the bent handle, simulating the actual installation state. The shape and size of the detection groove 37 are precisely designed according to the model of the bent handle to be detected, ensuring that the bent handle can pass smoothly during the flipping process, while the detector 38 can accurately detect its position.

[0037] Example 2:

[0038] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0039] The bracket 2 is symmetrically arranged on the top of the base 1. The outer side of the bracket 2 is inclined and has a protrusion 24 for limiting the detection seat 3, so that the detection seat 3 is tilted after installation, which facilitates the operator to perform the detection operation.

[0040] Specifically, the inner wall of the detection slot 37 and the outer side of the detection seat 3 are provided with through connection holes 23, and the outer side of the bracket 2 is provided with a second screw hole 25 corresponding to the position of the connection hole 23. The detection seat 3 is fixed on the bracket 2 by bolts or quick release mechanism to achieve quick installation and disassembly.

[0041] Specifically, the bracket 2 has a through mounting hole 21 on its outer side, and the base 1 has a first screw hole 22 corresponding to the position of the mounting hole 21 on its top. The bracket 2 is fixed to the base 1 by bolts to ensure the stability of the overall structure.

[0042] The remaining structure is the same as that in Example 1.

[0043] In this embodiment, the inclined design of the bracket 2 tilts the detection seat 3, facilitating operator observation and operation, and improving detection efficiency. The protrusion 24 engages with the corresponding structure on the detection seat 3, ensuring that the detection seat 3 is accurately positioned after installation and will not shift. The connecting hole 23 and the second screw hole 25 can use quick-release bolts or handle screws, facilitating quick replacement of different models of the detection seat 3 to meet the detection needs of various bent handles. The design of the mounting hole 21 and the first screw hole 22 ensures a secure connection between the bracket 2 and the base 1, while also facilitating disassembly and maintenance.

[0044] The workflow of this utility model is as follows:

[0045] When inspecting the refueling door handle, insert the handle of the refueling door into the notch 36, align the hinge hole for installing the refueling door handle with the lower limit rod 34, start the electric push rod 31, and the telescopic end of the electric push rod 31 pushes the upper limit rod 32 downward until both the upper limit rod 32 and the lower limit rod 34 are in the hinge hole opened on the refueling door handle and stop.

[0046] At this time, the installation of the refueling door handle can be simulated. By flipping the refueling door handle, the refueling door handle can be put into the detection groove 37. The position of the upper limit hole of the refueling door handle is detected by the detection rod 39 on the detector 38. At the same time, the quality of the produced refueling door handle is detected based on the smoothness of flipping the refueling door handle, and its qualification is determined, thus completing the inspection of the refueling door handle.

[0047] When it is necessary to test different fuel filler door handles, the test seat 3 can be removed from the bracket 2 and replaced with a suitable test seat 3 to test different models of fuel filler door handles.

[0048] 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.
