Problems solved by technology

However, it is difficult for a person in the driver's seat to determine the position of the wheel, and the vehicle often parks at an angle, resulting in inaccurate detection
[0004] In addition, the current detector uses infrared rays to make the lens of the detector face the headlights, but the lamp cover is transparent, and the light spots on the lampshade illuminated by infrared rays are very shallow, which is not easy to observe. Sometimes the reflection of the light receiving bowl causes the positioning to fail. , the positioning efficiency is not high
There is a certain distance from the bulb to the lampshade, and the distance is different for different models, which also affects the detection accuracy to a certain extent

Abstract

The invention relates to a high-precision agricultural machinery headlamp detector, and belongs to the field of detection. The detector comprises a transverse rail, a rotating shaft is fixed in the middle of the lower end face of the transverse rail and mounted in a shaft seat, the shaft seat is fixed on the ground, the transverse rail is parallel to the ground, and two ends of the transverse rail are respectively provided with a clamping and positioning device. One-time parking can ensure that the lens of the detector directly faces the headlamp, the driving longitudinal line of the vehicle is perpendicular to the lens, the vehicle does not need to be moved back and forth, and the detection precision and the detection efficiency are high.

Description

technical field [0001] The invention relates to a high-precision agricultural machinery headlamp detector, which belongs to the field of detection. Background technique [0002] With the rapid development of agricultural mechanization in the vast rural areas of our country, the number of agricultural machinery has increased dramatically. At the same time, higher requirements are put forward for the safety performance testing of agricultural machinery. According to the documents of the Ministry of Agriculture of the People's Republic of China and relevant national standards, the development of a device that can detect the luminous intensity and optical axis offset of the headlights of large, medium and small agricultural machinery vehicles that is convenient for agricultural machinery supervision departments at all levels to go to the countryside is called An urgent need. [0003] What generally use now is the mobile headlamp tester, as the patent of CN202229905U as publica...
