Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile detection, and in particular to a wheel guard detection tool and a detection implementation method. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] The wheel guard is a component located above the wheel that has the function of blocking splashes and flying stones generated when the wheel is running. According to Article 5.1.1 of the national standard GB7063-2011: In the area formed by two radial planes 30° forward and 50° backward from the center of the wheel, the width q of the wheel guard should be sufficient to cover the width b of the entire tire (b is the maximum width of the tire or wheel assembly specified by the manufacturer). In the case of dual tires, the tire width t should be the total installation width of the two tires.

[0004] There are two types of existing wheel guard plate inspection tools. One is a tooling table-type inspection tool, which uses the center hole of the wheel hub to position and fix the tooling table. After the tooling table is leveled with a spirit level, the tooling table limit device is used to perform width inspection on the wheel guard plate 30° forward and 50° backward. However, this type of tool is heavy and large in size, and has diameter requirements for the wheel hub positioning pin shaft, so it is less easy to operate and has poor universality. The other type is a vertical inspection tool, which is placed on the ground and adjusts the rotation center position of the measuring arm by translating the tooling and its vertical slide rail. However, this type of tool has poor positioning accuracy, resulting in large measurement errors. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a wheel guard plate detection tool and a detection implementation method, which realizes rapid positioning and fixing of the tool by adopting a method of fitting three claws to the tire; utilizes a gravity pointer perpendicular to the ground, and quickly realizes angle calibration of the tool by rotating an angle ruler; optimizes the structure of the measuring device, and the tool fits with the wheel guard plate in real time during the measurement process, so that the detection result is intuitive and accurate; and at the same time, the length of the claws can be adjusted according to the tire radius, which has good universality and can effectively improve the detection efficiency.

[0006] According to some embodiments, the present disclosure adopts the following technical solutions:

[0007] A wheel guard plate detection tool comprises a claw body, a circular hole is arranged at the symmetry center of the claw body, a pin shaft is fixed on the claw body through the circular hole; one end of the claw movable body is connected to the claw body through the circular hole and can rotate around the pin shaft;

[0008] The other end of the movable body of the claw and both ends of the main body of the claw are provided with movable guide grooves, and the claw is axially extended and retracted along the movable guide grooves. The claw is provided with scales, and the extension length of the claw is adjusted according to the radius of the tire. After the tread and the sidewall of the claw are in contact with the tire surface, the locking bolt is used to tighten the claw after the adjustment is completed, so as to realize the centering and fixation of the detection tool.

[0009] According to some embodiments, the present disclosure adopts the following technical solutions:

[0010] A detection implementation method of a wheel guard plate detection tool, comprising:

[0011] The length of the clamping jaws is adjusted according to the radius of the tire, and the clamping jaws rotate around the same pin to adjust the angle. When the three clamping jaws are in contact with the tire surface at the same time, the positioning and fixation of the detection tool can be quickly achieved; the measuring needle and the clamping jaws rotate around the same pin, and the length is automatically adjusted according to the shape of the wheel guard during the rotation measurement process to achieve contact with the wheel guard. By rotating the angle ruler so that the 0° scale of the angle ruler overlaps with the vertical pointer, the two radial planes 30° forward and 50° backward can be measured.

[0012] According to some embodiments, the present disclosure adopts the following technical solutions:

[0013] A non-transitory computer-readable storage medium is used to store computer instructions. When the computer instructions are executed by a processor, a detection implementation method of a wheel guard plate detection tool is implemented.

[0014] According to some embodiments, the present disclosure adopts the following technical solutions:

[0015] An electronic device comprises: a processor, a memory and a computer program; wherein the processor is connected to the memory, the computer program is stored in the memory, and when the electronic device is running, the processor executes the computer program stored in the memory so that the electronic device executes the detection implementation method of the wheel guard plate detection tool.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention discloses a wheel guard inspection tool, which has three claws whose lengths can be adjusted according to the radius of the tire. The claws can rotate around the same pin shaft to adjust the angle. When the three claws are in contact with the tire surface at the same time, the inspection tool can be quickly positioned and fixed. The measuring device and the claws rotate around the same pin shaft. At the same time, the measuring device has a telescopic function, which can automatically adjust the length according to the shape of the wheel guard during the rotation measurement process to achieve contact with the wheel guard. The tool is also provided with a pointer that is perpendicular to the ground through gravity, and an angle ruler with adjustable angles. By rotating the angle ruler so that the 0° scale of the angle ruler overlaps with the vertical pointer, the two radiating planes 30° forward and 50° backward can be accurately and intuitively measured.

[0018] The disclosed wheel guard detection tool solves the problems of heavy, difficult to operate, and large measurement errors of wheel guard detection devices. The tool is quickly positioned and fixed by using three clamping claws to fit the tire; the tool is quickly calibrated by rotating the angle ruler while the gravity pointer is perpendicular to the ground; the structure of the measuring device is optimized, and the tool fits the wheel guard in real time during the measurement process, so that the detection result is intuitive and accurate; at the same time, the tool can adjust the length of the clamping claw according to the tire radius, and has good universality and can effectively improve the detection efficiency.

[0027] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Example 1

[0030] A wheel guard plate detection tool disclosed in the present invention, such as Figure 1 As shown, the wheel guard plate detection tool comprises a claw body 1, a circular hole is arranged at the symmetry center of the claw body 1, and a pin shaft 3 is fixed on the claw body 1 through the circular hole; one end of the claw movable body 2 is connected to the claw body 1 through the circular hole and can rotate around the pin shaft 3;

[0031] Movable guide grooves are provided at the other end of the movable claw 2 and at both ends of the claw body 1. The first claw 4, the second claw 5 and the third claw 6 are axially extended and retracted along the movable guide grooves. The claws are marked with scales. The extended length of the claws is adjusted according to the radius of the tire. After the tread and the sidewall of the claws are in contact with the tire surface, the locking bolts are used to tighten them after the adjustment is completed to achieve the centering and fixation of the detection tool.

[0032] As an embodiment, as shown in 2, the centering and fixing functions of the tool are realized by a claw body 1, a claw movable body 2, a pin 3, a first claw 4, a second claw 5, a third claw 6 and a locking bolt 7. The claw body 1 is a rectangular structure of a fixed length (the specific length can be selected according to the tire diameter range of the measured vehicle model), and the length of the claw movable body 2 is half of the claw body 1.

[0033] The claw body 1 is provided with a movable guide groove of the claw, the first claw 4 and the second claw 5 can be extended and retracted in the axial direction, a circular hole is provided at the symmetric center of the claw body 1 to fix the pin 3, and the claw movable body 2 is provided with a movable guide groove of the claw, and the third claw 6 can be extended and retracted in the axial direction. A circular hole is provided at one end of the claw movable body 2 to rotate around the pin 3, and the other end is a plane, and the distance between the plane and the center of the pin is half of the claw base 1. The locking bolt is provided on the claw movable body and the claw body to fix the position of the claw.

[0034] The clamping jaws are scaled, and the extension length can be adjusted according to the tire radius. After the adjustment is completed, the locking bolt 7 is used to tighten to prevent the clamping jaws from moving. When the first clamping jaw 4, the second clamping jaw 5, and the third clamping jaw 6 are simultaneously attached to the tire surface on the tread and the sidewall, the centering and fixing of the detection tool are achieved.

[0035] Furthermore, the angle calibration function of the tool is realized by an angle ruler 8, a gravity pin 9 and a locking bolt 7. An angle ruler 8 is fixed through a circular hole at the symmetrical center position of the jaw body 1. The angle ruler 8 is scaled and its symmetrical center is 0°. A gravity pin 9 is set in the middle position of the angle ruler 8. One end of the gravity pin 9 is a semi-conical structure and the other end is a pointer. The middle circular hole structure passes through the pin 3 and rotates around the pin 3. Under the influence of gravity, the pointer is always perpendicular to the ground. After the three jaws are adjusted to the corresponding radius of the tire, they fit with the tire tread and sidewall, and the friction force can be used to fix the tool and the tire. During the measurement process, the tool body and the tire no longer have relative displacement; the gravity pin can rotate around the axis under the influence of gravity, but after the tool body and the tire are fitted and fixed (that is, after the angle between the tool and gravity is fixed), it no longer rotates relatively.

[0036] During the measurement process, only the measuring needle rotates around the axis of the angle ruler 8 with scales, and its symmetry center is 0°. The angle gradually increases towards both ends. By adjusting the deflection angle of the angle ruler 8, the 0° scale coincides with the pointer of the gravity needle 9, and the angle calibration of the tool is completed. After the angle calibration, the locking bolt 7 is used to fix the angle ruler 8 to prevent it from moving.

[0037] Furthermore, the measuring function of the tool is realized by the measuring needle guide groove 10, the measuring needle 11, and the spring 12. A circular hole is set at one end of the measuring needle guide groove 10 to realize rotation around the pin shaft 3, and a guide groove is set inside it to place the spring 12. The measuring needle 11 is set on the top of the spring to guide the measuring needle 11. A narrow boss is set near the angle ruler 8 to indicate the measuring angle. The part of the measuring needle 11 that contacts the wheel eyebrow is scaled and flush with the sidewall contact surface of the claw. Under the elastic force of the spring 12, the measuring needle will maintain contact with the wheel guard during the measurement process, reducing the error caused by visual inspection during measurement. The scale at the end of the measuring needle can be used to read the margin value of the wheel guard exceeding the tire width in real time.

[0038] Because all components rotate together around the pin 3, the tool can be folded and stored, making it convenient to transfer and use the tool.

[0039] As an example, Figure 3 , Figure 4As shown, the wheel guard detection tool disclosed in the present invention has three claws whose lengths can be adjusted according to the tire radius. The claws can rotate around the same pin shaft to adjust the angle. When the three claws are in contact with the tire surface at the same time, the detection tool can be quickly positioned and fixed. The measuring device and the claws rotate around the same pin shaft. At the same time, the measuring device has a telescopic function, which can automatically adjust the length according to the shape of the wheel guard during the rotation measurement process to achieve contact with the wheel guard. The tool is also provided with a pointer that is perpendicular to the ground through gravity, and an angle scale with adjustable angles. By rotating the angle scale so that the 0° scale overlaps with the vertical pointer, the two radiating planes 30° forward and 50° backward can be accurately and intuitively measured.

[0040] Example 2

[0041] In one embodiment of the present disclosure, a detection implementation method of a wheel guard plate detection tool is provided, which is implemented by a wheel guard plate detection tool, wherein the wheel guard plate detection tool comprises a claw body 1, a circular hole is arranged at the symmetry center of the claw body 1, and a pin shaft 3 is fixed to the claw body 1 through the circular hole; one end of a claw movable body 2 is connected to the claw body 1 through the circular hole and can rotate around the pin shaft 3;

[0042] Movable guide grooves are provided at the other end of the movable claw 2 and at both ends of the claw body 1. The first claw 4, the second claw 5 and the third claw 6 are axially extended and retracted along the movable guide grooves. The claws are marked with scales. The extended length of the claws is adjusted according to the radius of the tire. After the tread and the sidewall of the claws are in contact with the tire surface, the locking bolts are used to tighten them after the adjustment is completed to achieve the centering and fixation of the detection tool.

[0043] As an embodiment, the specific steps of a detection implementation method of a wheel guard plate detection tool disclosed in the present invention are as follows:

[0044] First, according to the tire radius of the vehicle to be measured, adjust the extension length of the claws using the scale on the claws, and use the locking bolts to fix the claws. Because the distance from the claws to the pin is consistent with the tire radius, the three claws are simultaneously clamped on the sidewall and tread, which means that the pin of the tool is coaxial with the tire center axis, and the tool and the tire are relatively fixed.

[0045] Using the characteristic that the gravity needle always points vertically to the ground, adjust the angle of rotation of the angle ruler so that the 0° scale of the angle ruler coincides with the gravity needle, and then use the locking bolt to lock the angle ruler. This process can realize the calibration of the tool to the vertical center plane of the wheel. After that, using the scale on the angle ruler, the area to be measured of the wheel guard can be quickly quantified during the measurement operation.

[0046] When measuring, rotate the measuring needle guide groove. Under the action of the spring, the measuring needle will keep in contact with the vehicle wheel guard. Then, the width of the wheel guard relative to the tire can be observed in real time through the scale on the side of the measuring needle, so as to quickly achieve quantitative measurement of the wheel guard width at different angles.
