Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection tooling, in particular to a fuel filler port position detection and verification tooling. Background Art
[0002] A vehicle fuel tank, also commonly referred to as a fuel tank, is a container used to store fuel in a car or other motor vehicle. The main function of this container is to ensure that there is enough fuel to supply the engine during driving so that it can operate normally.
[0003] The angle of the fuel tank filler neck must be within the designed range. Otherwise, it can interfere with surrounding objects, adversely affecting vehicle modifications. Furthermore, any angle deviation can prevent the fuel gun from being properly inserted, significantly impacting fuel volume. The existing process involves welding the filler neck to the tank using equipment, then securing the tank and then welding the filler neck. However, this fixed tank can easily deviate and be difficult for personnel to identify, leading to the filler neck being welded in the wrong position. Therefore, post-weld inspection of the filler neck is often required.
[0004] In the existing technology, whether the fuel filler port is properly installed is often detected by manual visual verification or by using other devices to detect whether it will cause interference. A fuel gun is also needed to detect whether it can be inserted normally. The entire detection process is relatively slow and the steps are cumbersome. There is also the possibility of inaccurate detection. Once the detection is wrong, it is easy to have an adverse effect on the subsequent use of the vehicle. Utility Model Content
[0005] The purpose of this utility model is to provide a fuel filler position detection and verification tool to solve the following technical problems:
[0006] How to quickly detect and check the position of the fuel tank's refueling port; the purpose of the utility model can be achieved through the following technical solutions:
[0007] A fuel filler port position detection and verification tool is used to detect the position of the fuel filler port on a fuel tank, where the fuel filler port is located at the chamfer of the fuel tank; it includes a detection plate, the inner side of which has the same shape as the chamfer of the fuel tank; a standard port connected to the detection plate is installed on the outer side of the detection plate, the installation position of the standard port is a preset standard position, and the inner diameter of the standard port is larger than the outer diameter of the standard fuel filler port of the fuel tank.
[0008] As a further solution of the present invention: the inner diameter of the standard port is 3-8 mm larger than the outer diameter of the preset standard refueling port of the fuel tank.
[0009] Beneficial effects of the utility model:
[0010] The utility model aligns the inner side of the detection plate in the tooling with the outer side of the fuel tank, and then puts the standard port on the fuel filling port so that the inner side of the detection plate fits the outer side of the fuel tank. At this time, it is observed from the curved side of the detection plate to judge whether the curved side of the detection plate fits the outer side of the fuel tank. If they fit, it means that the fuel filling port position of the fuel tank meets the requirements. If not, it means that the fuel filling port position of the fuel tank does not meet the standards. The operation is simple, convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Example 1
[0018] The utility model discloses a fuel filler port position detection and verification tool for detecting the position of the fuel filler port on a fuel tank. Generally, the corner of the fuel tank is usually set as a chamfered structure, and the fuel filler port is set at the chamfered position; for different fuel tanks, the fuel filler port is set at different preset standard positions, and the preset standard position is the qualified installation position of the fuel filler port, which is formulated according to the actual situation of the fuel tank.
[0019] See also Figure 1-2The tooling consists of a test plate 100 and a standard port 200. The test plate 100 is an arc-shaped plate, and the shape of its inner side is the same as the outer shape of the chamfered part of the fuel tank where the refueling port is provided. When the test plate 100 fits and covers the chamfered part of the fuel tank, the inner side of the test plate 100 is completely fitted with the outer side of the fuel tank; the standard port 200 is installed at a preset standard position on the outer side of the test plate 100, and the standard port 200 is connected to the test plate 100, forming an integrated test and verification tooling.
[0020] See also Figure 3 The inner wall shape of the standard port 200 is exactly the same as the outer wall shape of the preset standard refueling port of the fuel tank, and the inner diameter of the standard port 200 is larger than the outer diameter of the preset standard refueling port of the fuel tank. In order to make the standard port 200 flexibly mounted on the refueling port to be tested, the inner diameter of the standard port 200 is set to be 3-8 mm larger than the outer diameter of the preset standard refueling port of the fuel tank.
[0021] Specifically, when conducting the inspection, you only need to align the inner side of the inspection plate 100 in the tooling with the outside of the fuel tank, and then put the standard port 200 on the fuel tank port so that the inner side of the inspection plate 100 fits the outside of the fuel tank. At this time, observe from the curved side of the inspection plate 100 to determine whether the curved side of the inspection plate 100 fits the outside of the fuel tank. If so, it means that the fuel tank fuel port position meets the requirements. If not, it means that the fuel tank fuel port position does not meet the standards. The operation is simple, convenient and fast.
