Description
The utility model is a kind of portable intelligent verticality measuring instrument, belongs to the form and position error measurement field.
The special-purpose precision measuring instrument that is used at present metrological service's measuring vertical degree at home, most supplementary angle measuring principles of using, form by the multi-grade lever gear train, measuring error is big, and be confined to operation under the constant temperature, generally adopt try square in the production line, specially-used measuring instruments such as square chest, with light gap method the error of perpendicularity is made an estimate, can not intuitively accurately reflect element to be measured actual error size, the intellectuality of being unrealized of the electricity of nearest domestic appearance indication try square measuring instrument, can not be applied to industry spot, more advanced abroad is with three-coordinate measuring machine measuring vertical degree, but to the environmental requirement strictness, can not be applied to industry spot, and introduce one more than at least 200 ten thousand yuan, prices are rather stiff.
It is a kind of for dual-purpose portable, the high precision of laboratory and industry spot, intelligent verticality measuring instrument that the purpose of this utility model just is to provide, and installs and precision machined needs to satisfy large-scale try square calibrating and industry spot large-scale precision equipment.
The utility model utilizes upper and lower two working faces upset to eliminate the invariant system error by principle for 180 °, sensor, single-chip microcomputer are combined, the mechanical measuring means that changes qualitative estimation in the past is that exact figure quantitatively directly perceived is measured, instrument is furnished with LCD LCD, nickel-cadmium battery group, panel type mini-printer and touch key-press, thin film switch, make it can overcome dynamometry and Temperature Influence, improve measuring accuracy and efficient, and have memory and show, printing function, in the laboratory and industry spot all can use, have the very high ratio of performance to price.
Measuring principle of the present utility model is as follows:
Verticality measuring instrument sensor 1, sensor 2 be in the horizontal direction at a distance of Δ X, at vertical direction at a distance of the h(definite value)
1. the line value error (be the error of perpendicularity) of exterior angle on the H height of establishing try square is L, and the line value error on the h height is L1, and the exterior angle is less than normal in 90 ° (as shown in Figure 2).
Detect the error of perpendicularity of try square with verticality measuring instrument.When L1＞Δ X: be placed on the reference platform try square motionless, verticality measuring instrument is moved to the try square direction lightly along reference platform and positioning fixture, when rigidly connecting, the contact of sensor 2 touches the long limit (being the H limit) of try square, when being in the state that will move and move (critical conditions), the gauge head of sensor 1 touches the long limit of try square already, its displacement is reflected by sensor 1, reading a
1A then
1=L1-Δ X.If verticality measuring instrument moves gently to the try square long side direction again, at this moment on the sensor 2 displacement is arranged, its number is b, so: a
1=L1-Δ X+b

Formula (3) is the mathematic(al) representation of the error of perpendicularity of try square exterior angle on the h height.Simultaneously, when L1＜Δ X,, can get same formula by above-mentioned measuring method and step.No matter Δ X is greater than L1 or less than L1, all passes through 180 ° of measuring instrument upsets have been eliminated error the most outstanding superiority of the new measuring method of this verticality that Here it is fully in measuring process.
(2) it is bigger than normal in 90 ° direction to establish the exterior angle of try square, in like manner can derive:
L1＝－1／2［（［（b
2－b
1）－（a

Symbol "+" expression try square exterior angle in formula (3) and the formula (4) is less than normal in 90 ° direction; "-" expression try square exterior angle is bigger than normal in 90 ° direction.
(3) can get by the elementary geometry relation: L/L1=H/h L=H * L1/h
Formula (3) substitution following formula is got:
L＝H／2h［（b
