When the center height is measured, a pin rod is manually inserted into a pin hole of the piston, the piston is placed on a measuring table, the height of the pin rod on one side of the piston is measured, then the piston is rotated 180 degrees on the measuring table, then the height of the pin rod on the other side is measured, and the center height of the piston can be obtained after the obtained data are processed;
the piston compression height is the distance from the center of the pin bore to the top surface of the piston. When the compression height is measured, the pin hole of the piston to be measured is penetrated into the pin rod of the measuring instrument, the height distance from one side of the top of the piston to the axial lead of the piston pin hole is measured, the piston is taken out, the pin rod is penetrated from the other side of the piston, the height distance from the top of the other side to the axial lead of the piston pin hole is measured, and finally the data of the compression height of the piston is obtained.
The measurement mode needs repeated measurement, the piston needs to be moved in the middle, the detection progress is seriously influenced, people cannot reach the detection progress after a long time, the efficiency is reduced, and the phenomena of wrong detection and missed detection can occur.
