Automobile wheel guard plate measuring device

Abstract

An automobile wheel guard plate measuring device comprises a supporting device, a measuring device body and a leveling device. The supporting device comprises a bearing platform and a connecting device, a vertical plate is arranged in the middle of one side of the bearing platform, a first through hole is formed in the middle of the vertical plate, the connecting device comprises a three-jaw chuckclamped with a tire center hole, and a chuck connecting pin shaft is mounted at the axis of the three-jaw chuck; the measuring device body comprises an angle ruler backup plate, a maximum angle limiting pin shaft, a minimum angle limiting pin shaft, a measuring platform and a laser ranging ruler arranged on the angle ruler backup plate and / or the measuring platform, wherein the maximum angle limiting pin shaft and the minimum angle limiting pin shaft are arranged on the inner side of the vertical plate. The angle ruler backup plate comprises a fan-shaped guiding rule with scales at the two ends and a rotary disc arranged at the lower end of the fan-shaped guiding rule, a second through hole matched with the chuck connecting pin shaft is formed in the middle of the rotary disc, a clampinggroove is formed in the periphery of the other end of the chuck connecting pin shaft, and the other end sequentially penetrates through the first through hole and the second through hole and then is fixedly clamped with a clamping spring matched with the clamping groove; the suspension measurement guarantees the accuracy of experimental data, and a plurality of regulation requirements can be measured at the same time.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile wheel guard measuring device. Background technique [0002] The wheel guard is a component that is located above the wheel and has the function of blocking the splash and flying stones generated when the wheel is running. [0003] At present, the "GB7063-2011 Automobile Wheel Guard" standard belongs to the compulsory inspection project of automobiles; [0004] Such as Figure 15 As shown, the "GB7063-2011 Automobile Wheel Guard" standard requires: [0005] Article 5.1 On a level road surface, when the vehicle is in the ready state, with 2 passengers sitting in the front row, and the wheels are in the linear position (driving position), the wheel guards shall meet the following requirements. [0006] Article 5.1.1 In the area formed by two radiation planes 30° forward and 50° backward from the center of the wheel, the width q of the wheel guard should ...

AI Technical Summary

Problems solved by technology

[0011] The current test method is mainly to place the measuring equipment on the ground. There is generally a large error in the calibration and positioning of the wheel center, and the measurement process is relatively complicated. The measurement of the conforming items at 30° and 50° angles requires a lot of manual setting of parameters, and the cooperation of multiple people is required to complete the measurement. The process is relatively cumbersome and the measurement error is large
