Abstract

The invention discloses detection equipment and method based on the basic diameter of a piston, and relates to the technical field of piston detection, the detection equipment comprises a mounting seat and a U-shaped frame mounted on one side of the mounting seat, and a distance measurement calibration piece is arranged on one side, away from the U-shaped frame, of a positioning seat. According to the device, the distance measurement calibration part is arranged, an infrared distance measurement sensor is started to measure the distance between a first calibration plate and one end of the infrared distance measurement sensor, and when a first servo motor drives a transmission shaft to rotate by 90 degrees, the first calibration plate moves to the inner side of a first storage bin; when the variable quantity of the numerical value on the infrared distance measuring sensor is equal to the distance between the first calibration plate and the second calibration plate, it is indicated that the infrared distance measuring sensor is in a normal operation state. In this way, the measurement data of the infrared distance measuring sensor can be calibrated, and the accuracy of the data detected by the infrared distance measuring sensor is further improved.
