Abstract
The invention belongs to the field of industrial automatic detection, and particularly relates to a high-precision sensor detection mechanism which comprises a sensor protection shaft, a high-precision distance measuring sensor, a guide shaft sleeve and a transition block. The sensor protection shaft is of a hollow shaft-shaped structure; the high-precision distance measuring sensor is fixedly arranged in an inner cavity of the sensor protection shaft in the axial direction, and a measuring head of the high-precision distance measuring sensor faces the lower end of the sensor protection shaft. The guide shaft sleeve is coaxially arranged at the lower part of the inner cavity of the sensor protection shaft, and the lower end surface of the guide shaft sleeve is flush with or basically flush with the lower end surface of the sensor protection shaft; the transition block is sleeved in the guide shaft sleeve in an axial sliding manner, the lower end face of the transition block extends out of the guide shaft sleeve and the lower end face of the sensor protection shaft, and a preset gap is formed between the upper end face of the transition block and the measuring head. The slidable transition block is used for replacing a sensor measuring head to directly contact with a measured surface, so that pollutants such as oil stain and dust are effectively isolated, and the measuring head is kept clean and the measuring precision is kept.
