tuning hole 49 which is right above the cylindrical test piece and the axis of which is vertical to and intersected with the axis of the guide cylinder 36, and when the push rod motor 4 gradually extends out of the push rod, the infrared ray emitted by the third infrared distance measuring sensor 32 is in contact with the outer circumferential wall of the cylindrical test piece when the cylindrical test piece gradually passes through the heights of the third infrared distance measuring sensor 32 and the fourth infrared distance measuring sensor 33, so that the distance to the outer circumferential wall of the cylindrical test piece can be dynamically measured, the third infrared distance measuring sensor 32 shows that the axis of the cylindrical test piece is equal to the third infrared distance measuring sensor 32 when the third infrared distance measuring sensor 32 measures the shortest distance, the numerical value c of the horizontal distance between the third infrared distance measuring sensors 32 at the left part and the right part of the first supporting frame 31 is fixed, so the press machine main body 1 automatically calculates the code difference between the numerical value c and the numerical value d of the shortest distance measured by the third infrared distance measuring sensor 32, the diameters of the front part, the middle part and the rear part of the cylindrical test piece can be obtained, meanwhile, the infrared rays emitted by the fourth infrared distance measuring sensor 33 are contacted with the front end surface and the rear end surface of the cylindrical test piece, so the distance between the front end surface and the rear end surface of the cylindrical test piece can be dynamically measured, and the numerical value e between the two fourth infrared distance measuring sensors 33 is fixed, so the press machine main body 1 automatically calculates the code difference between the numerical value e and the numerical value f of the distance measured by the two fourth infrared distance measuring sensors 33, the height of the cylindrical test piece can be obtained, if the front end surface and the rear end surface of the cylindrical test piece are not completely flat, the flatness of the cylindrical test piece can be evaluated by analyzing the real-time change of the algebraic difference between the value e and the value f, and the permanent magnet 42 is positioned in the middle of the inner cavity of the guide cylinder 36 at the moment, so that the infrared rays emitted by the second infrared distance measuring sensor 26 can pass through the fine tuning hole 49 right above the cylindrical test piece at the moment, and for the fine tuning hole 49 not positioned right above the cylindrical test piece (namely, the fine tuning holes 49 with a certain number below the front of the dovetail seat 35), the infrared rays emitted by the second infrared distance measuring sensor 26 can not pass through (namely, the second infrared distance measuring sensor 26 can measure the horizontal distance to the corresponding mounting plate 46 or the fine tuning disc 48 or the guide plate 41), and because the value g of the horizontal distance between the second infrared distance measuring sensor 26 and the adjacent contact pin 44 is not changed, therefore, the difference between the value h and the value g measured by the second infrared distance measuring sensor 26 should be smaller than and closest to the calculated height of the cylindrical test piece, and when the outer circumferential surface of the cylindrical test piece is not smooth or the difference between the front diameter and the rear diameter of the cylindrical test piece is large, the height of the contact pin 44 directly above the cylindrical test piece is inconsistent, so that each fine tuning hole 49 is not coaxial, and in serious cases, the corresponding fine tuning hole 49 cannot be penetrated by the second infrared distance measuring sensor 26, and then the difference between the value h and the value g is far smaller than the calculated height of the cylindrical test piece, that is, the smoothness of the circumferential surface of the cylindrical test piece or the vertical angle between the circumferential surface and the front end surface do not meet the standard requirement, and before measurement, the axes of the fine tuning holes 49 with different apertures can be intersected and perpendicular to the axis of the guide cylinder 36 by manually rotating each fine tuning disc 48, and then the purpose of adjusting the range through which the infrared ray of the second infrared distance measuring sensor 26 can pass is achieved, therefore, the purpose of adjusting the contrast standard is achieved, namely the aperture of the fine adjustment hole 49 is the floating range of the contact pin 44, when infrared rays cannot pass through the fine adjustment hole 49, the smoothness of the corresponding part of the outer circumferential surface of the cylindrical test piece or the vertical angle between the corresponding part and the front and rear end surfaces does not meet the standard requirement, the flatness, the height, the diameter and the perpendicularity between the end surfaces and the outer circumferential surface of the cylindrical test piece can be detected one by controlling the alternate operation of the intermittent rotation of the stepping motor 17 and the intermittent reciprocating action of the lower push rod motor 4, so that the detection accuracy is improved, meanwhile, the omission of the problem part is reduced, and the circumferential test piece meeting the requirement can be vertically placed at the top end of the test board for pressure test after the detection is finished.

The foregoing is a preferred embodiment of the present invention, and it will be appreciated by those skilled in the art that changes, modifications, substitutions and variations may be made in the embodiments without departing from the principles and spirit of the invention, which is further defined in the appended claims.
