Illustrate the working principle and measurement mechanism of vertical bar inclinator below with reference to specifically used step:
Specifically used step:
The taper of vertical bar to be measured need to be learnt in advance using the measuring instrument device, in general, taper is equal to bottom for circular cone
Face diameter is exactly that bottom surface circular diameter subtracts top surface circular diameter again than upper height for rotary table than upper height.Taper is circular cone
An important parameter, in general, the full range of sizes of electric power bar meets national standard, therefore can be with apparent electric power bar
Taper.This instrument is not the disadvantage is that be capable of measuring the electric power bar of unknown taper.

Effect, keep measurement angle bar 2 abut vertical bar.Inclination sensor 14 in instrument can measure itself tilt angle (with
Ground is referential).
In this step, it would be desirable to it learns, inclination sensor 14 and measurement angle bar 2 are a rigid connection structures,
Inclination sensor 14 is the measurement sensor using ground as absolute coordinate, therefore inclination sensor 14 can directly reflect measurement
The current state (state of crest line 24) of angle bar 2.When measurement angle bar 2 is abutted vertical bar, it is believed that measurement angle bar 2 and vertical bar
It is also rigid connection, inclination sensor 14 can directly reflect the heeling condition of vertical bar at this time.What the heeling condition of vertical bar referred to
It is the heeling condition of the bar center line, if to obtain the heeling condition of center line by measuring angle bar 2, needs to subtract measurement angle
The angle of the crest line 24 of iron 2 and center line, this angle is a unfixed angle, the opening angle of it and measurement angle bar 2 and
The taper of vertical bar has relationship, and when both of which determines, this angle is also determined.In processor processing, need to will only incline
The tilt angle of oblique sensor 14 itself subtracts this angle, so that it may obtain the tilt angle of vertical bar, the i.e. inclination of vertical bar
Angle=14 tilt angles of inclination sensor-included angle-vertical bar angle of taper to be measured；
Inclination sensor 14 can be monitored in real time the state of itself, and the installation of inclination sensor 14 is fixed (for example surveys
The crest line 24 of angulation iron 2 is exactly perpendicularly to inclination sensor 14), obtain the actual angle of inclination for measuring 2 crest line 24 of angle bar at this time,
Horizontal xy axis should be divided herein, to measure the line of 2 crest line 24 of angle bar and center line as x-axis, it is vertical it be y-axis, in x-axis to
Surveying vertical bar, there are fixed angles with measurement 2 crest line 24 of angle bar, therefore, x-axis gradient=crest line 24x axis inclination angle of vertical bar to be measured
Degree-fixed angle -3 angle of taper of vertical bar to be measured；
The y-axis gradient of vertical bar to be measured=crest line 24y axis tilt angle.
The calculating of fixed angle and proof formula are as follows:
Guess:
Angle formed by the center line of circular cone and the crest line of angle bar is a fixed angle, and only with the taper of circular cone and
The variation of the opening angle of angle bar and change.
It proves:
If conical bottom radius surface be R, a height of L,
Using circular cone bottom surface as X-axis, Y-axis, a height of Z axis establishes rectangular coordinate system in space, as shown in figure 5, a plane A is taken,
The plane and conical surface are tangent, and the plane is by point A (X1, Y1, Z1), vertex C (0,0, L) on the circle of bottom surface；Its expression formula is such as
Under:
A plane B tangent with conical surface is taken again, and the plane is by point B (X2, Y2, Z2), vertex C on the circle of bottom surface
(0,0, L)；Its expression formula is as follows:
Assuming that the opening angle of angle bar is 90 °, then plane A is perpendicular to plane B, therefore its normal line vector is vertical；X1Y1
It is in the round coordinate taken of taking up an official post in bottom surface, for convenience of calculating, if X1=0, Y1=R；
The intersection equation of available two planes are as follows:
Thus equation can obtain its direction vector are as follows:
And the centerline direction vector of circular cone are as follows:
(0,0,1)
Thus angle equation between the two can be calculated:
Taper B=2R/L is enabled, is obtained:
Card is finished
It is verified through SW2016 software modeling, calculated result is accurate.
Measurement part and measurement angle bar 2 in this instrument are detachable member, difference can be selected to open according to the actual situation
The measurement angle bar 2 of bicker degree measures, prism and cylindrical measurement method be it is the same, select the measurement angle bar 2 of different angle
Purpose be guarantee instrument installation stability and size applicability.
