Step 3, after the end face distance value is obtained, the movable piston rod 401 of the movable cylinder 40 of the measuring device is retracted, and the measuring device 50 is reset upwards, so that the end face distance of the transmission housing 20 is measured.
It should be noted that:
Before the transmission shell end face distance measuring equipment is put into use, a standard workpiece is used for calibration, namely the end face distance of the standard workpiece is measured, the measuring sensor 532 is compressed, the compressed position of the measuring sensor 532 when the standard workpiece is measured is recorded, the position is marked as a zero point in a program of a controller, and therefore when the common workpiece is measured, the measured value of the measuring sensor 532 is the difference value between the end face distance of the measuring workpiece and the end face distance of the standard workpiece, and the measured value of the end face distance of the measuring workpiece can be accurately obtained. Because the end face distances of the two types of workpieces are different, the zero mark positions and the numerical values of the end face distances of the standard workpieces in the corresponding measuring procedures of the two types of workpieces are different, and therefore, two different measuring procedures are required to be started when the two types of workpieces are measured.
In summary, the device for measuring the end face distance of the transmission shell can accurately measure the distance between two end faces of the transmission shell, has high measurement accuracy and high measurement efficiency, has good measurement reproducibility, and can effectively ensure the service life of the transmission.
The present invention is not limited to the above-described specific embodiments, and various modifications may be made by those skilled in the art without inventive effort from the above-described concepts, and are within the scope of the present invention.
