S4: when the cam is measured, the electric push rod (4) and the stepping motor can be operated by connecting the control switch with a power supply, when the electric push rod (4) operates, the limiting frame (5) provided with the laser measuring instrument (7) can be driven to slide on the supporting plate (3), so that the two groups of positioning blocks can be conveniently positioned, when in measurement, the two groups of positioning blocks are moved away, the laser measuring instrument (7) is operated, and simultaneously the stepping motor can be operated to slowly drive the cam to rotate, and when the cam rotates, the laser measuring instrument (7) performs base point measurement on the profile of the cam, because the profile of the cam is irregular and smooth, the laser measuring instrument (7) obtains different data when measuring the cam, and when the cam rotates for a circle, the numerical value of the profile of the cam can be obtained through the laser measuring instrument (7);
s5: when the cam is further measured, the position of the cam can be further adjusted on the measured result data, the position of the laser measuring instrument (7) is unchanged, then the position of the inner sleeve (83) is adjusted upwards in the outer sleeve (81) on the basis, the height of the cam can be accurately adjusted through the mark size (13) at the front end of the outer sleeve (81), the cam is adjusted to a position away from the position and increased by one centimeter, and the profile of the cam is measured again through the laser measuring instrument (7);
S6: when the cam is further measured, the position of the cam can be further adjusted on the measured result data, the position of the laser measuring instrument (7) is unchanged, then the position of the inner sleeve (83) is adjusted upwards in the outer sleeve (81) on the basis, the height of the cam can be accurately adjusted through the mark size (13) at the front end of the outer sleeve (81), the cam is adjusted to a position which is away from the position and descends by one centimeter, and the profile of the cam is measured again through the laser measuring instrument (7);
s7: in summary, the three sets of measured data are compared, if the three sets of measured data are the same, the cam profile is qualified, otherwise, the data are different, and the cam is unqualified.
