Technical Field

[0001] This utility model relates to the field of automotive testing technology, and in particular to a portable automotive accelerator pedal inspection tool. Background Technology

[0002] In the automotive manufacturing industry, the surface precision and positioning stability of the side sheet metal at the fuel filler neck are crucial. Currently, existing fuel filler neck opening inspection fixtures primarily use two locating pins as references in the Z and X directions, respectively, and rely on edge protrusions to achieve Y-direction positioning. However, this traditional fixture has significant shortcomings in practical applications:

[0003] The inspection process is prone to scratches and wear: During the inspection operation, the positioning structure is prone to scratches with the part being inspected, which will accelerate the wear of the fixture, thereby affecting the service life of the fixture and the inspection accuracy.

[0004] High requirements for the environment of the parts and difficult assembly: When the precision of the parts being inspected is poor, there will be difficulties in assembly or even no assembly at all, which greatly limits the applicability of traditional inspection tools.

[0005] Poor stability and highly susceptible to human operation: The structural design of traditional inspection tools results in insufficient stability, making them easily affected by human operation during the inspection process, and making it difficult to guarantee the consistency and reliability of the inspection results.

[0006] Low inspection efficiency: The combination of the above problems makes traditional inspection tools inefficient, unable to meet the needs of the automotive manufacturing industry for high-efficiency inspection, and also increases time and production costs.

[0007] Therefore, there is an urgent need for a new type of inspection tool that can improve detection accuracy, enhance positioning stability, adapt to different parts environments, and is easy to operate. Utility Model Content

[0008] In view of this, the present invention provides a portable car refueling gate detector to solve the problem of detecting the small refueling gate of a car.

[0009] To achieve the above objectives, the technical solution of this utility model is to provide a portable car fuel filler valve inspection tool, comprising: a tool body, a positioning component, a pressure head, a clamping plate, and a rotating shaft. The positioning component, the pressure head, and the clamping plate are all disposed on one side of the tool body. The rotating shaft passes through the tool body and is rotatably connected to the tool body, and one end of the rotating shaft is connected to the clamping plate. The positioning component is used to abut against the side wall of the car fuel filler valve, and the rotating shaft is used to drive the clamping plate to rotate so that the end of the clamping plate away from the rotating shaft cooperates with the pressure head to clamp or release the side sheet metal of the car fuel filler valve.

[0010] Preferably, the positioning component includes a first positioning element and a second positioning element, both of which are disposed on the gauge body. The first positioning element is used to abut against the side wall of the filler neck along a first direction, and the second positioning element is used to abut against the side wall of the filler neck along a second direction. The first direction and the second direction form an angle.

[0011] Preferably, there are four first positioning elements, which are located around the body of the inspection fixture.

[0012] Preferably, the first positioning member is provided with an abutting groove, which is disposed on the surface of the first positioning member in the first direction and is used to abut against the side wall of the filler port. The abutting grooves of the two first positioning members located on the upper side of the fixture body are opposite in orientation to the abutting grooves of the two first positioning members located on the lower side of the fixture body.

[0013] Preferably, there are two second positioning elements, which are respectively disposed on opposite sides of the inspection fixture body along the second direction.

[0014] Preferably, the second positioning member is provided with an abutting protrusion, which is disposed on one side of the second positioning member in the second direction, and the abutting protrusions of the two second positioning members are oriented in opposite directions, respectively for abutting against the side walls on both sides opposite to the oil filler port.

[0016] Preferably, a clamping block is provided at the end of the clamping plate away from the rotating shaft, and the clamping block extends toward the pressure head.

[0017] Preferably, the inspection tool body is also provided with a handle, which is located on the side of the inspection tool body away from the oil filler port.

[0018] Preferably, there are four pressure heads, four clamping plates, and four rotating shafts. The four rotating shafts are connected to one end of the four clamping plates, and the four clamping plates cooperate with the four pressure heads to clamp or release the side panel sheet metal.

[0019] Compared with the prior art, the portable car refueling gate gauge provided by this utility model has the following advantages:

[0020] During testing, the fixture body can be fixed to the filler neck via the clamping plate and pressure head, eliminating the need for manual external force to press the fixture body and preventing scratches during testing. The assembly of the fixture body and the filler neck side panel is also simple.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1-2 This utility model provides a portable car fuel filler inspection tool for inspecting the surface of the sheet metal side panel of the car fuel filler. It includes a tool body 1, a positioning component 2, a pressure head 3, a clamping plate 4 and a rotating shaft 5. The positioning component 2, the pressure head 3 and the clamping plate 4 are all disposed on one side of the tool body 1. The rotating shaft 5 passes through the tool body 1 and is rotatably connected to the tool body 1. One end of the rotating shaft 5 is connected to the clamping plate 4.

[0027] The positioning component 2 is used to abut against the side wall of the car's fuel filler neck, and the rotating shaft 5 is used to drive the clamping plate 4 to rotate so that the end of the clamping plate 4 away from the rotating shaft 5 cooperates with the pressure head 3 to clamp or release the side sheet metal of the car's fuel filler neck.

[0028] Understandably, when using a portable car fuel filler inspector to inspect the side panel of a car's fuel filler neck, the inspector body 1 is first inserted into the fuel filler neck, causing the positioning component 2 to abut against the surrounding side walls of the filler neck, thus positioning the inspector body 1 and the filler neck. At this point, the clamping plate 4 is located inside the filler neck, while the pressure head 3 abuts against the outer surface of the filler neck's side panel. Next, the rotating shaft 5 is rotated, causing the clamping plate 4 to rotate to a position where its end away from the rotating shaft 5 corresponds to the pressure head 3. That is, the end of the clamping plate 4 away from the rotating shaft 5 abuts against the inner surface of the filler neck's side panel, and the pressure head 3 abuts against the outer surface of the filler neck's side panel. In this way, the clamping plate 4 and the pressure head 3 can be used to clamp the filler neck's side panel, thereby fixing the inspector body 1 at the filler neck. Finally, the surface of the filler neck's side panel is inspected by checking the gap between the outer periphery of the inspector body 1 and the filler neck's side panel. For example, after the fixture body 1 is fixed at the oil filler port in the above manner, the gap between the outer surface of the side sheet metal and the fixture body 1 is checked by a feeler gauge to see if it is qualified.

[0029] It should be noted that the fuel filler neck of the car is a through hole opened in the side panel sheet metal so that the fuel gun can pass through the fuel filler neck to fill the fuel tank. The gap between the clamping plate 4 and the pressure head 3 must be able to meet the requirements of clamping the side panel sheet metal, that is, the gap between the two parts cannot be greater than the thickness of the side panel sheet metal.

[0030] It should be noted that the clamp 4 can be rotatably connected to one side of the fixture body 1 and connected to one end of the rotating shaft 5, and rotate relative to the fixture body 1 by the drive of the rotating shaft 5. Alternatively, it can be directly connected to one end of the rotating shaft 5 without being connected to the fixture body 1.

[0031] Using the above method, the fixture body 1 can be fixed to the oil filler port during testing via the cooperation of the clamping plate 4 and the pressure head 3. No manual external force is required to press the fixture body 1, preventing scratches during testing. Furthermore, the assembly of the fixture body 1 and the side panel sheet metal of the oil filler port is simple. Simultaneously, after the clamping plate 4 and the pressure head 3 hold the side panel sheet metal, the testing personnel only need to test the gap difference between the fixture body 1 and the side panel sheet metal, without needing to support the fixture body 1. Therefore, the testing process is highly stable, unaffected by manual operation, and highly efficient.

[0032] Furthermore, the positioning component 2 includes a first positioning element 21 and a second positioning element 22, both of which are disposed on the fixture body 1. The first positioning element 21 is used to abut against the side wall of the filler neck along a first direction, and the second positioning element 22 is used to abut against the side wall of the filler neck along a second direction. The first direction and the second direction form an angle.

[0033] It is understood that the first positioning member 21 and the second positioning member 22 are used to abut against the edge sidewall of the oil filler port from the first direction and the second direction respectively when the gauge body 1 is inserted into the oil filler port, so as to position the gauge body 1 and the oil filler port.

[0034] Preferably, the first direction is perpendicular to the second direction.

[0035] In this embodiment, the first direction is the Z-axis direction, the second direction is the X-axis direction, and the direction of the fixture body 1 toward the filler port is the Y-axis direction. Thus, the fixture body 1 and the filler port can be positioned on the XZ plane by the first positioning member 21 and the second positioning member 22. The pressure head 3 fits against the surface of the filler port side sheet metal from the Y-axis direction and cooperates with the clamping plate 4 to clamp the inner and outer surfaces of the side sheet metal, thereby realizing the positioning of the fixture body 1 in the X, Y, and Z-axis directions.

[0036] Furthermore, there are four first positioning elements 21, which are located around the body of the inspection fixture 1.

[0037] It is understandable that the arrangement of the first positioning members 21 is adapted to the shape of the oil filler port so that the four first positioning members 21 can just abut against the side wall of the oil filler port, thereby positioning the inspection fixture body 1 in the first direction.

[0038] Furthermore, the first positioning member 21 is provided with an abutment groove 211, which is located on one side of the first positioning member 21 in the first direction and is used to abut against the side wall of the oil filler. The abutment grooves 211 of the two first positioning members 21 located on the upper side of the inspection fixture body 1 are opposite to the abutment grooves 211 of the two first positioning members 21 located on the lower side of the inspection fixture body 1.

[0039] It is understandable that the upper and lower sides of the gauge body 1 are respectively the side away from the ground and the side close to the ground. Among the four first positioning members 21, the two first positioning members 21 located on the upper side of the gauge body 1 abut against the side wall of the filler port away from the ground through the abutting groove 211, while the two first positioning members 21 located on the lower side of the gauge body 1 abut against the side wall of the filler port close to the ground through the abutting groove 211.

[0040] Furthermore, there are two second positioning elements 22, which are respectively arranged on opposite sides of the inspection fixture body 1 along the second direction.

[0041] Understandably, the two second positioning elements 22 abut against the side walls on opposite sides of the filler neck along the second direction.

[0042] Furthermore, the second positioning member 22 is provided with an abutment protrusion 221. The abutment protrusion 221 is disposed on one side of the second positioning member 22 in the second direction, and the abutment protrusions 221 of the two second positioning members 22 face opposite directions, respectively for abutting against the side walls on both sides opposite to the oil filler port.

[0043] It is understandable that the arrangement of the second positioning member 22 is adapted to the shape of the filler port, that is, the distance between the two second positioning members 22 is adapted to the distance between the two side walls of the filler port along the second direction.

[0044] Furthermore, the pressure head 3 includes a base 31 and a pressure block 32. The base 31 is connected to the fixture body 1, and the pressure block 32 is disposed on the side of the base 31 away from the fixture body 1.

[0045] Understandably, by adjusting the height of the base 31 and the pressure block 32, it can be adapted to side sheet metal of different thicknesses.

[0046] Furthermore, a clamping block 41 is provided at the end of the clamping plate 4 away from the rotating shaft 5, and the clamping block 41 extends toward the pressure head 3.

[0047] Understandably, by adjusting the extension distance of speed 41, it is also possible to adapt to side sheet metal of different thicknesses.

[0048] Furthermore, the fixture body 1 is provided with a reference hole 11 that penetrates the fixture body. The reference hole 11 is used to detect and position the fixture body 1 so as to detect the surface of the fixture body 1.

[0049] It is understandable that the fixture body 1 may be damaged or deformed due to external factors during long-term use, resulting in poor detection results. By positioning the fixture body 1 through the reference hole 11, the surface of the fixture body can be inspected to determine whether there is damage or deformation.

[0050] Furthermore, there are three reference holes 11, which correspond to the positioning references detected by the three coordinate systems.

[0051] It is understandable that by setting three reference holes 11, the three-coordinate system positioning of the fixture body 1 can be achieved. For example, the first reference hole 11 achieves the positioning of the X-axis coordinate, the second reference hole 11 achieves the positioning of the Y-axis coordinate, and the third reference hole 11 achieves the positioning of the Z-axis coordinate. The specific means of inspecting the surface of the fixture body 1 are not limited here, as long as the surface of the fixture body 1 can be inspected after positioning the fixture body 1.

[0052] Furthermore, the fixture body 1 is also provided with a handle 12, which is located on the side of the fixture body 1 away from the oil filler port, and is used to apply external force to the fixture body 1.

[0053] Understandably, by applying external force to the gauge body 1 through the handle 12, the gauge body 1 can be moved toward or away from the filler neck.

[0054] Furthermore, there are four pressure heads 3, four clamping plates 4, and four rotating shafts 5. The four rotating shafts 5 are connected to one end of the four clamping plates 4 respectively, and the four clamping plates 4 cooperate with the four pressure heads 3 respectively to clamp or release the side sheet metal.

[0055] It should be noted that shims may be provided on the pressure head 3 and / or clamping plate 4 to provide cushioning when clamping the side panel sheet metal and to avoid scratching the side panel sheet metal.

[0056] It is understandable that by setting four pressure heads 3, clamping plates 4 and rotating shafts 5, the stability of the gauge body 1 and the sheet metal side panel of the oil filling port can be improved.

[0057] Compared with existing technologies, the portable car fuel filler inspector provided by this utility model can fix the inspector body to the fuel filler neck during testing by means of a clamp and a pressure head, eliminating the need for manual external force to press the inspector body and preventing scratches during testing. Furthermore, the assembly of the inspector body and the side panel sheet metal of the fuel filler neck is simple. Simultaneously, after the clamp and pressure head hold the side panel sheet metal, the inspector only needs to test the gap difference between the inspector body and the side panel sheet metal, without needing to support the inspector body. Therefore, the testing process is highly stable, unaffected by manual operation, and highly efficient.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
