Description

Technical Field

[0001] This utility model belongs to the field of automotive parts inspection tools, specifically relating to the dimensional inspection of automotive fuel filler cap hinges. Background Technology

[0002] like Figure 6 The shown are the hinge parts for the filler cap and the rotating shaft of the filler cap (e.g., Figure 6 The center position of the axis (as shown at point b) relative to the mounting hole and mounting surface (as shown in the image) Figure 6 The position shown at point a) has precision requirements. The position of the rotating shaft directly affects the fit between the fuel filler cap and the vehicle body. Therefore, the position of the rotating shaft must be strictly controlled. Because the part is irregularly shaped, it cannot be inspected using conventional measuring tools.

It cannot quickly detect the position of the center of the axis of the rotating shaft of the fuel filler cap relative to the mounting hole and mounting surface, and cannot control the factory pass rate of the parts, which does not meet the needs of actual production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a car fuel filler cap hinge inspection tool, including a base plate 1 and a foot pad 5 fixed to the bottom of the base plate 1. A flip detection component 10 is installed on the upper surface of the base plate 1. A positioning component 9 is installed on the lower right side of the flip detection component 10 and is fixed to the base plate 1. At the same time, two sets of clamps 8 are provided on the right side of the positioning component 9. The clamps 8 are provided to facilitate clamping and fixing the fuel filler cap hinge part to be inspected. Detection pins 11 are installed on both sides of the flip detection component 10. The positioning component 9 includes positioning pins 901 and positioning blocks 902. Positioning pins 901 are provided in the center of each positioning block 902. The two positioning holes of the fuel filler cap hinge part to be inspected are respectively aligned with the two positioning pins 901 on the positioning component 9 to facilitate positioning and fixing the fuel filler cap hinge part to be inspected.

[0022] In this example, one end of the detection pin 11 is a sleeve structure, so that the rotation shaft of the filler cap hinge part to be tested can be inserted into the sleeve.

[0023] The flip detection assembly 10 in this example includes a fixed base 1001, a connecting block 1002, a fastening pin 1003, a rotating pin 1004, a flip arm 1005, a rotating block 1006, and a guide sleeve 1007. The connecting block 1002 is mounted on the fixed base 1001, with a fastening pin 1003 mounted at one end of the connecting block 1002 and a rotating pin 1004 at the other end. The flip arm 1005 is disposed within the connecting block 1002. One end of the rotating arm 1005 is movably mounted in the opening groove of the connecting block 1002 via a fastening pin 1003 and a rotating pin 1004. Meanwhile, the other end of the rotating arm 1005 is connected to a rotating block 1006. Guide sleeves 1007 are provided on both sides of the rotating block 1006, and a detection pin 11 is installed in the guide sleeve 1007. A rotating pin 1004 is provided to allow the rotating arm 1005 to rotate. The fastening pin 1003 is used to fix the rotating arm 1005, and the guide sleeve 1007 is used to install the detection pin 11.

[0024] In this example, the base plate 1 has two pin storage devices 6 installed on the upper surface of the base plate 1. The pin storage devices 6 are used to store the test pins 11.

[0025] In this example, handles 2 are provided on both sides of the base plate 1. The handles 2 are made of aluminum and are fixed to both sides of the base plate 1 with screws. The handles 2 make it easy to hold and move the inspection tool.

[0026] In this example, three reference hole protective covers 3 and a large inspection tool nameplate 7 are fixed at the four corners of the base plate 1. The reference hole protective covers 3 on the upper surface of the base plate 1 all have coordinate nameplates 4 on their inner sides.

[0027] In this example, the reference hole protective cover 3, the pin retainer 6, the clamping device 8, the positioning component 9, and the flip detection component 10 are respectively installed on the upper surface of the base plate 1 by screws or rivets, which facilitates the installation and disassembly of each component.

[0028] In this example, the foot pads 5 are locked to the bottom of the base plate 1 by threaded fastening, and there are four foot pads 5. The foot pads 5 are made of rubber and are used to support the entire inspection fixture.

[0029] Working principle: When using this automotive fuel filler cap hinge inspection tool, first open the flip-over inspection component 10 and the two sets of clamps 8. Then, align the two positioning holes of the fuel filler cap hinge part to be inspected with the two positioning pins 901 on the positioning component 9, and place the fuel filler cap hinge part to be inspected on the positioning component 9. Then, close the two sets of clamps 8 to clamp it, ensuring that the positioning surface of the part is in contact with the two positioning blocks 902 on the positioning component 9. After the inspection is successful, the part can be inspected. When inspecting the part, close the flip-over inspection component 10 to the working state and insert the inspection pins 11. Then, push the inspection pins 11 on both sides inward. The front part of the inspection pin 11 is designed as a sleeve structure. (The inner diameter of the sleeve of the inspection pin 11 is designed according to the positional tolerance of the rotating shaft marked on the part drawing.) When the inspection pin 11 is pushed inward, if the sleeve can fit over the rotating shaft of the filler cap, it means that the positional tolerance of the rotating shaft of the filler cap relative to the positioning datum is within the tolerance of the drawing, and the part is qualified. If the sleeve cannot fit over the rotating shaft of the filler cap, it means that the positional tolerance of the rotating shaft of the filler cap relative to the positioning datum exceeds the tolerance requirements of the drawing, and the part is unqualified. After the inspection is completed, open the flip inspection assembly 10 and the two sets of clamps 8, and remove the part. This completes the entire work.
