Automobile straightening device

Abstract

The invention relates to the technical field of motor vehicle detection, in particular to an automobile straightening device. Comprising a front axle straightener and a rear axle straightener, the front axle straightener is arranged in front of the rear axle straightener, and longitudinal center lines of the front axle straightener and the rear axle straightener are collinear. The left side and the right side of the front shaft straightening device and the left side and the right side of the rear shaft straightening device are roller areas, and the middle is a power transmission area. The power transmission area is provided with a power transmission device, and the power transmission device comprises an air cylinder, two push plates, a guide rail and a connecting rod mechanism. The Z-shaped connecting rod is matched with the left and right push plates, so that the structural arrangement is compact and reasonable, and synchronous left and right movement and consistent movement distance are ensured. The front axle straightening device forms a groove structure to forcibly enable the center line of a front axle of the vehicle to coincide with the center line of front axle equipment, so that the detection precision is guaranteed. The straightening precision can reach 1 degree, the overall design thickness can reach 100 mm (not including the height of a bottom face push plate), and the device can be suitable for non-one floor of a multi-floor building (such as a light test room).

Description

technical field [0001] The invention relates to the technical field of motor vehicle detection, in particular to a vehicle straightener. Background technique [0002] In order to ensure the safety of the car at night, in addition to having sufficient illuminance, the car headlights also have requirements for the limit of the offset of the headlight axis. When testing the headlamp tester, it is required to ensure that the longitudinal axis of the car is perpendicular to its guide rail, and to keep the headlamp at a standard distance from it (depending on the model of the headlamp tester). It can be known from theoretical calculation that when the longitudinal axis of the vehicle is not perpendicular to the guide rail of the headlamp detector, the offset is 2°, so that the optical axis offset of the light beam at 10m will reach 350mm, so it is necessary to ensure that the longitudinal axis of the vehicle is not perpendicular to the front of the vehicle during actual detection....

AI Technical Summary

Problems solved by technology

The traditional car adjuster can only be used in the first floor structure of the building (car inspection station, etc.), and cannot be used in the non-first floor of the multi-storey building (such as lighting laboratory, etc.) due to the influence of the thickness of the floor.

To sum up, the traditional car adjuster has the disadvantages of large use limitations, large space occupation, time-consuming installation and commissioning, and inconvenient adjustment and maintenance.
