As shown in fig. 1 to 4, a preferred embodiment of a stud assembly verticality detection device of the present invention includes a sleeve 1, an inner hole of the sleeve 1 is arranged to match an outer diameter of a stud 3, and a lower end surface of the sleeve 1 is arranged vertically to an axis of the sleeve 1; a plurality of comparison mechanisms 2 are arranged on the outer periphery side of the sleeve 1 at intervals, and the comparison mechanisms 2 comprise a fall detection mechanism 21 and a fall amplification mechanism 22; the drop detection mechanism 21 comprises drop detection pieces 211 and elastic pieces 212, wherein the lower part of the sleeve 1 is provided with a flange 11, the lower ends of the drop detection pieces 211 vertically slide through the flange 11 and extend to the lower part of the sleeve 1, the elastic pieces 212 are arranged between the bottoms of the drop detection pieces 211 and the flange 11, and two ends of the elastic pieces 212 are respectively elastically abutted with the drop detection pieces 211 and the flange 11; the head amplifying mechanism 22 includes head amplifying members 221, and first rotating shafts 222 provided at the ends of the first ends of the head amplifying members 221, each head amplifying member 221 being disposed opposite to the corresponding head detecting member 211 up and down, the head amplifying members 221 being hinged to the upper outer side of the sleeve 1 by the first rotating shafts 222 rotating up and down. The alignment mechanism 2 further includes links 23, and the top of the drop detector 211 is hinged to the lower ends of the links 23, and each link 23 extends upward and is hinged to the lower side of the corresponding drop amplifier 221.
Wherein, because the diameter of the inner hole of the sleeve 1 is the same as the diameter of the stud 3, when the stud 3 is deformed, the sleeve 1 cannot be sleeved into the stud 3, and at the moment, the sleeve 3 can check whether the stud 3 is deformed; when the stud 3 is not deformed, after the stud 3 is welded on the base 4, the sleeve 1 is sleeved on the stud 3, the sleeve 1 is pressed downwards, so that the lower end face of the sleeve 1 is in contact with the end face of the base 4, before the lower end face of the sleeve 1 is in contact with the end face of the base 4, the lower end faces of the drop detectors 211 slide upwards along the axial direction of the sleeve 1 under the action of the top pressure of the end face of the base 4, after the lower end face of the sleeve 1 is in contact with the end face of the base, if the vertical degree value between the stud 3 and the end face of the base 4 is larger, the distance value fluctuation between the lower end face of each drop detector 211 and the lower end face of the sleeve 1 is larger, therefore, the drop detector 211 can convert the detection of the vertical degree between the stud 3 and the base 4 into the detection of the distance fluctuation range between the lower end face of the drop detector 211 and the lower end face of the base 1, the arrangement of the elastic piece 212 enables the lower end face of the drop detector 211 to be in stable contact with the end face of the base 4, and the drop detector 211 to reset smoothly; the lever amplification structure is formed among the connecting rod 23, the drop amplification piece 221 and the sleeve 1, when the drop detection piece 211 slides upwards, one end of the drop amplification piece 221, which is far away from the sleeve 1, can amplify and display the distance between the lower end face of the drop detection piece 211 and the lower end face of the sleeve 1, and by observing the angle between each drop amplification piece 221, the distance fluctuation range between the lower end face of each drop detection piece 211 and the lower end face of the sleeve 1 can be more accurately obtained, namely, the perpendicularity between the stud 3 and the base body 4 after welding can be accurately obtained, and the perpendicularity detection precision requirement between the stud 3 and the base body 4 is met.
Specifically, each drop detection member 211 is a guide post, and a limit protrusion 2111 extending outwards along the radial direction of the drop detection member 211 is arranged at the upper part of each drop detection member 211; each elastic member 212 applies a downward elastic force to the corresponding drop detection member 211, so that the lower end surface of the corresponding drop detection member 211 protrudes from the lower end surface of the sleeve 1, and the lower end surface of the limiting protrusion 2111 is blocked by the upper end surface of the protrusion 11. Wherein, the limit protrusion 2111 is provided with a third rotating shaft, and the lower end of the connecting rod 23 is connected with the third rotating shaft. When each drop detection piece 211 is in a free state, each drop detection piece 211 elastically stretches the lower end face of the sleeve 1 under the action of the corresponding elastic piece 212, and the distances between the lower end face of each drop detection piece 211 and the lower end face of the sleeve 1 are equal.
In this embodiment, the elastic member 212 is a compression spring, the compression spring is sleeved on the outer peripheral side of the drop detection member 211, the lower end of the compression spring is connected with the lower end of the drop detection member 211, and the upper end of the compression spring abuts against the lower end face of the flange 11. Specifically, the lower end of the compression spring is fixed or detachably connected with the lower end of the guide post, when the lower end face of the guide post is not in contact with the base body 4, the lower end of the guide post extends out of the sleeve for the longest distance, and when the lower end face of the guide post abuts against the end face of the base body 4, the guide post contracts upwards under the pressure action of the base body 4.
The first rotation shaft 222 may be disposed at an end of the first end of the drop amplification member 221, or may be disposed at a position of the drop amplification member 221 near the first end, so long as the hinge point between the connecting rod 23 and the drop amplification member 221, the first rotation shaft 222, the drop amplification member 221 and the drop amplification member 221 form a lever amplification mechanism, that is, amplification display of a distance between the lower end surface of the drop detection member 211 and the lower end surface of the sleeve 1 can be achieved, and adjustment of an amplification factor of the drop amplification mechanism can be achieved by adjusting a length of the drop amplification member 221, a position of the first rotation shaft 222 on the swing arm, and a hinge point position between the connecting rod 23 and the drop amplification member 221. By observing the height difference of the second ends of the drop-height amplifying members 221, the operator can accurately determine the perpendicularity between the stud 3 and the end surface of the base 4.
In this embodiment, the first rotating shaft 222 is disposed at an end of the first end of the drop amplifier 221, and the bottom surface of the drop amplifier 221 is provided with a second rotating shaft near the first rotating shaft 222, and the upper end of the connecting rod 23 is rotatably connected with the second rotating shaft. The first rotation shaft 222 is disposed at the end of the head amplifying member 221, so that the overall structure of the stud assembly verticality detecting device is more compact, and the stud assembly verticality detecting device can be applied to a narrow operation space.
To further facilitate operator alignment, the alignment mechanism 2 further includes a reference member 24 extending radially outwardly of the sleeve 1, the reference member 24 being disposed between adjacent ones of the step-up members 221. The perpendicularity between the stud 3 and the end face of the base body 4 can be accurately judged by observing the included angle between the reference member 24 and the fall amplifying member 221.
Specifically, when the lower end surface of the fall detection piece 211 is flush with the lower end surface of the sleeve 1, the fall amplification piece 221 and the reference piece 24 are arranged in parallel. As shown in fig. 2, when the stud 3 is completely perpendicular to the substrate 4, the sleeve 1 is sleeved on the stud 3, and after the sleeve 1 is pressed downwards, the lower end surfaces of the drop detection pieces 211 are all flush with the lower end surface of the sleeve 1, so that it is more convenient for a detector to quickly and intuitively judge the perpendicularity condition between the stud 3 and the end surface of the substrate 4.
In this embodiment, the fall amplifying member 221 and the reference member 24 are each provided in a fan-like plate shape, and when the lower end surface of the fall detecting member 211 is flush with the lower end surface of the sleeve 1, the fall amplifying member 221 and the reference member 24 are combined into an annular plate. Wherein, there are eight of the alignment mechanisms 2, and eight of the alignment mechanisms 2 are uniformly arranged around the outer peripheral side of the sleeve 1.
The application method of the stud assembly perpendicularity detection device of the embodiment is as follows: firstly, sleeving a sleeve 1 on a stud 3, and pushing the sleeve 1 along the axial direction of the stud 3 to enable the lower end face of the stud 3 to prop against the end face of a base body 4, wherein the lower end faces of all drop detectors 211 prop against the end face of the base body 4 under the action of elastic force, so that the distances between the lower end faces of all drop detectors 211 and the lower end face of the sleeve 1 are staggered; thus, the arrangement of the sleeve 1 and the drop detector 211 enables the measurement of the perpendicularity between the stud 3 and the end face of the base body 4 to be converted into the detection of the distance value between the lower end face of each drop detector 211 and the lower end face of the sleeve 1; then, the second end of the drop amplifying member 221 is driven by the connecting rod 23 to rotate relative to the first rotating shaft 222, so that the small distance value between the lower end surface of each drop detecting member 211 and the lower end surface of the sleeve 1 is amplified into the height difference of the second end of the drop amplifying member 221, and the detecting personnel can intuitively and accurately judge the verticality range between the stud 3 and the base 4 by judging the height distribution of the second end of each drop amplifying member 221.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
