Three-freedom degree wheel positioning instrument target

Abstract

The invention discloses a three-freedom degree wheel positioning instrument target in the field of car industries, which aims to solve the problem that the traditional target can not carry out position adjustment and has lower precision. The device comprises a target plate (1), target plate support angle iron (2), a target shaft connecting frame (3), a fan-shaped frame (4), a connecting fork (5), a connecting pipe (6), a connecting shaft (7) and a rotating shaft (8), wherein one end of the connecting shaft (7) is rotatably matched and connected with an inner hole of the connecting pipe (6); the connecting pipe (6) is welded with the bottom of the connecting fork (5); the rotating shaft (8) penetrates through the connecting fork (5) and a through hole at the circle center position of a cambered groove of the fan-shaped frame (4) and extends out of the end part of the through hole and is threaded by a butterfly nut; the top surface of the target shaft connecting frame (3) is fixedly connected with a bottom bolt of the fan-shaped frame (4); two target plate support angle irons (2) are welded in the target plate (1), and the target shaft connecting frame (3) is fixedly connected with bolts of the target plate support angle iron (2).

Description

technical field [0001] The invention relates to an inspection device in the field of automobile inspection, more specifically, it relates to a three-degree-of-freedom wheel aligner target. Background technique [0002] In order to ensure the handling stability of the car, the installation between the wheels, steering knuckle and axle shaft of the car has a certain relative position, which is called wheel alignment. The wheel alignment parameter detection system is usually referred to simply as a four-wheel aligner or a wheel aligner. Wheel aligner is the most important testing equipment for checking wheel alignment. At present, there are more than 30,000 wheel aligners in the country, and the number is increasing at an annual rate of 30%. [0003] With the development of automobile detection technology, the detection method of wheel alignment based on vision sensor has been paid more and more attention by researchers because it can realize non-contact and automatic measure...

AI Technical Summary

Problems solved by technology

[0004] The existing wheel aligner targets are all fixed targets, which cannot be adjusted in position and have low precision, making it difficult to meet the requirements of the national standard for wheel alignment detection
