Specific implementation mode：
Present disclosure is described further below in conjunction with attached drawing.
As depicted in figs. 1 and 2, a kind of auxiliary device for automobile pipe fitting high-acruracy survey of the present invention, is used for
High precision measuring instrument is coordinated to carry out high-acruracy survey to tested automobile pipe fitting comprising three support legs 1, pedestal 2, ventilation are led
Pipe 3, precision-sleeve 4 and positioning adjust block 5；The measurement part of tested automobile pipe fitting can be entered high by the precision-sleeve 4
The measured zone of precision measure instrument；Three support legs 1 are fixed on the lower surface of pedestal 2, and the center of pedestal 2 opens up a ladder
Through-hole 21, the upper part of ladder hole 21 is formed with precision-sleeve 4 to be interference fitted, the lower part of ladder hole 21 and adjustable height
The positioning adjust block 5 of degree coordinates；The periphery of pedestal 2 opens up four upper partially communicating susceptor through-holes 22 with ladder hole 21,
The periphery of precision-sleeve 4 opens up four sleeve through hole 41, and four susceptor through-holes 22 correspond respectively with four sleeve through hole 41
Coordinate, can be inserted into clearance fit an airway 3 in each susceptor through-holes 22 and corresponding sleeve through hole 41, ventilation is led
Pipe 3 stretches into one end 31 of precision-sleeve 4 and overlaps with the inner wall circular arc of precision-sleeve 4, and the other end 32 of airway 3 can be with
The ventilating glue tube of high precision measuring instrument is connected to；In order to not influence the beat of operation is measured, better ensures that in measurement process and make
The happy property of industry, one end that preferred ventilation catheter 3 stretches into precision-sleeve 4 have the circle concentric with the inner wall circular arc of precision-sleeve 4
Arcuation.
In fig. 2, three support legs 1 point centered on the center of pedestal 2 is formed is uniformly distributed for each 120 ° between any two,
And it is fixed in a manner of screw locking.
In fig. 2, there are one perpendicular 51, the perpendicular 51 can coordinate the lower part tool of positioning adjust block 5
Screw locking mode adjusts the height of positioning adjust block 5, to which control is tested the compression distance of automobile pipe fitting.
In the present invention, since the precision prescribed for being tested automobile pipe fitting is high, preferably the material of precision-sleeve 4 is wear-resisting hard steel
Class material can improve the service life of precision-sleeve 4 and ensure the accuracy of measurement accuracy in this way.
As shown in figure 3, the airway 3 is in " dry " font, one end 32 that airway 3 is located at outside pedestal 2 has
Taper can make the ventilating glue tube of high precision measuring instrument more smoothly be inserted in the airway 3, and mutually form with sealing
The air-breather of effect；It is too deep that the middle part annular projection 33 of " dry " font then has the function of that limitation ventilating glue tube assembles.Due to
High precision measuring instrument, which measures and is tested the outer diameter of automobile pipe fitting, to be measured by principles such as ventilation flow rates, so logical
There cannot be cast appearance during gas, in order to ensure that measurement accuracy, the preferably described airway 3 will not get rusty using brass etc.
The material to fall off is also ensured that measurement cost is not high in this way.
As shown in Figure 2 and Figure 4, on the same line, and axis is the same as always for the axis in four susceptor through-holes 22 two-by-two
The height of two susceptor through-holes 22 of line be more than other two axis collinear susceptor through-holes 22 height；Four sleeves
Axis in through-hole 41 two-by-two on the same line, and axis collinear two sleeve through hole 41 height be more than in addition
Height of two axis in collinear sleeve through hole 41；Since in this way, tested automobile pipe fitting designated depth can be ensured
Outer diameter.
In Fig. 4, since tested automobile pipe fitting and 4 matched gap of precision-sleeve are very small, when ventilation measures
Making tested automobile pipe fitting, bounce, in order to avoid such defect occurs, preferably exists to influence the accuracy of measurement data upwards
The inner wall of precision-sleeve 4 opens up four and runs through slot 42 in the axial direction, and four a pair of through slot 42 and four sleeve through hole 41 1
It answers, every is at least partly connected to through slot 42 with corresponding sleeve through hole 41, so as to allow measurement gas to discharge in time, in turn
Do not influence the measurement accuracy of tested automobile pipe fitting.
In measurement process, survey crew is firstly the need of the height for adjusting positioning adjust block 5, to ensure to be tested automobile pipe
Part fathoms；Then high precision measuring instrument is calibrated using calibrated bolck, is confirming that high precision measuring instrument is feasible
Afterwards, then the measurement part of tested automobile pipe fitting is stretched into and enters measured zone in precision-sleeve 4, then rotation is high more than 180 °
The specific size for being measured point can be shown in the display of precision measure instrument simultaneously, and distinguishes area with green, red two kinds of colors
Divide the qualification of tested automobile pipe fitting and unqualified attribute.
