Be described in further detail below in conjunction with the height measuring instrument of accompanying drawing to the technical program.
See also Fig. 1, the height measuring instrument 100 that the technical program embodiment provides comprises base 10, guide rod 20, extension rod 30 and height gage 40.
Base 10 has first surface 12 and second surface 14.Described first surface 12 is parallel relative with second surface 14.First surface 12 is the plane, and it is used for carrying element to be measured.
Guide rod 20 is fixed in base 10 and vertical with base 10, and is namely vertical with first surface 12.Guide rod 20 is approximately right cylinder.
Extension rod 30 comprises sliding part 31, the first extension 32, the second extension 33, fixed screw 34, connecting portion 35 and horizontal bubble instrument 36.The first extension 32 and the second extension 33 are provided with a junction 35 away from an end of guide rod 20, are used for connecting the first extension 32 and the second extension 33, thereby the second extension 33 can and rotate relative to these connecting portion 35 slips.In the present embodiment, described connecting portion 35 is a coupling bolt.
Sliding part 31 is approximately cylindric, and internal aperture is slightly larger than the external diameter of guide rod 20 matching with guide rod 20.Sliding part 31 slidably is sheathed on guide rod 20, with so that extension rod 30 can be along the moving axially of guide rod 20, thus the distance of regulating the first surface 12 of extension rod 30 relative bases 10.One end of sliding part 31 is connected with fixed screw 34.Fixed screw 34 is used for sliding part 31 lockings, so that the relative guide rods of sliding part 31 20 are fixing, thereby makes the extension rod 30 relative guide rods 20 that are fixed in of fixing with sliding part 31.
One end of the first extension 32 and sliding part 32 are fixing, and it is parallel to the first surface 12 of base 10.The other end of the first extension 32 has a connecting hole 322 that matches with connecting portion 35.
The second extension 33 is parallel with the first extension 32.The second extension 33 away from an end of guide rod 20 have can sheathed level altitude rule 40 through hole 302.
The second extension 33 offers sliding tray 334 along extending axis direction.Sliding tray 334 is made of two semi-circular hole 336 that are positioned at two ends and the slot 338 that is communicated with described two semi-circular hole 336.The equal diameters of the width of slot 338 and semi-circular hole 336.Thereby connecting portion 35 can pass connecting hole 322 and sliding tray 334, to be connected and fixed the second extension 33 and the first extension 32.
Horizontal bubble instrument 36 is fixedly arranged on the second extension 33, is used for judging whether level of the second extension 33.
Height gage 40 comprises activity measuring staff 41, precise measure device 42 and measures probe 43.Height gage 40 is located at extension rod 30 away from an end of guide rod 20 and perpendicular to base 10, is used for moving along the direction perpendicular to extension rod 30 and base 10.
Activity measuring staff 41 vertical sleeves are located at extension rod 30, and it can move relative to the direction of extension rod 30 along the first surface 12 of vertical base 10.
Precise measure device 42 is fixed in activity measuring staff 41 away from an end of base 10, is used for an amount to obtain probing height value that 43 measurements are arrived.
Measure probe 43 and be fixed in activity measuring staff 41 near an end of base 10, be used for contacting to obtain element to be measured at the height value that measures probe 43 correspondence positions with element to be measured.
The height measuring instrument 100 of the technical program utilizes the second extension 33 relative to the slip of the first extension 32 and rotates, and has enlarged to measure the zone, has improved measurement efficient.
The method that the technical program embodiment also provides a kind of height that utilizes above-mentioned height measuring instrument 100 to treat measuring sensor to measure, it may further comprise the steps:
The first step provides element 200 to be measured and above-mentioned height measuring instrument 100.
See also Fig. 2, described element 200 to be measured has three positions to be measured, i.e. primary importance A, second place B and the 3rd position C.Wherein, the bearing of trend of described primary importance A, second place B and the first extension 32 is in same rectilinear direction, and the bearing of trend of described the 3rd position C and the first extension 32 is not in same rectilinear direction.
Second step makes zero height measuring instrument 100.
See also Fig. 3, probe 43 is close to the first surface 12 of base 10 with measuring, until it contacts with first surface 12, and the displayed value of precise measure device 42 is returned to zero.At this moment, height measuring instrument 100 is take the height at first surface 12 places as reference zero.
The 3rd goes on foot, and element 200 to be measured is positioned over the base 10 of height measuring instrument 100.
See also Fig. 4, element 200 to be tested is positioned over the first surface 12 of described base 10, make the bottom surface of element 200 to be tested fit in first surface 12, and the primary importance A that makes element 200 to be tested and the measurement of height gage 40 are popped one's head in 43 relative.
The 4th step, the height of measurement primary importance A.
Make to measure probe 43 to moving near base 10 directions, until it contacts with the primary importance A position of element 200 to be tested, can read from precise measure device 42 the height value H1 at primary importance A place.
The 5th step extended to second place B position with the second extension 33, measured the height of second place B.
See also Fig. 5, unclamp connecting portion 35, the second extension 33 is extended to second place B position, make to measure probe 43 and contact with second place B position, tighten connecting portion 35.
Regulate the elasticity of connecting portion 35, make the bubble of horizontal bubble instrument 36 be in horizontality, thus the second extension 33 levels.Then, read the height value H2 of second place B position from precise measure device 42.
The 6th step turned to C position, the 3rd position with the second extension 33, measured the height of the 3rd position C.
See also Fig. 6, unclamp connecting portion 35, the second extension 33 is turned to C position, the 3rd position, make to measure probe 43 and contact with the 3rd position C, tighten connecting portion 35.
Regulate the elasticity of connecting portion 35, make the bubble of horizontal bubble instrument 36 be in horizontality, thus the second extension 33 levels.Then, read the height value H3 of C position, the 3rd position from precise measure device 42.
Certainly, if measure the height of the relative primary importance A of second place B, also can make and measure probe 43 and contact with primary importance A position, precise measure device 42 is made zero, make again to measure probe 43 and contact with second place B position, then can from precise measure device 42, directly read the height of the relative primary importance A of second place B.
With respect to prior art, the height measuring instrument of the technical program and height-measuring method have following advantage: at first, it utilizes extendible the second extension to extend to needs to measure element to be measured at the height of this position after the length again, has enlarged to measure the zone; Secondly, it can measure element to be measured at the height of another location after utilizing the rotation of the second extension, need not move element to be measured, has not only enlarged to measure the zone, has also improved measurement efficient.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to the technical conceive of the technical program, and all these change the protection domain that all should belong to the technical program claim with distortion.
