Description
Technical field
The present invention relates to fields of measurement, be specifically related to bulk pick-up unit and detection method.
Background technology
In actual production, often need relative installation between detection two parts whether correct, but due to the scrambling of parts, ruler, vernier caliper, tape measure etc. cannot be adopted directly to measure.
Such as, in Fig. 1, protect solar or lunar halo 1, between vehicle frame 2 and engine assembly 3, there is assembly relation, if there is engine assembly 3 fan and protect the problems such as position that is uneven, engine assembly 3, gap between solar or lunar halo 1 is inaccurate, will cause fan and protect solar or lunar halo 1 dynamic interference until fan damages, and power transmission angle changes and causes transmission efficiency to reduce.But protect solar or lunar halo 1, after vehicle frame 2 assembled with engine assembly 3, due to the scrambling of respective shape and the complicacy of various line arrangement, the conventional survey instruments such as tape measure cannot be adopted directly to measure.
In prior art, the first detection mode is manual indirect detection, is exactly that testing staff applies the positions of testing tool to the position and engine assembly 3 of protecting solar or lunar halo 1 such as ruler, bevel protractor, vernier caliper, tape measure and detects.Concrete operation method is as follows:
On the top airfoil 5 of vehicle frame 2, a selected basic point 6 is as initial point, then protecting a selection check point 4 on solar or lunar halo 1, engine assembly 3 selects a check point 8.Basic point and check point are the unique point of parts, such as circular hole, bolt, boss etc.
When measuring the distance between basic point 6 and check point 4, interference because of pipeline 9 causes between 2 cannot line measurement, now first measure the height of check point 4 apart from the top airfoil 5 of vehicle frame 2 with ruler, need check point 4 to be moved to above the top airfoil 5 of vehicle frame 2 by flat tool, or the top airfoil 5 of vehicle frame 2 is moved to below check point 4; Then measure the distance of the outside of belly 7 of check point 4 and vehicle frame 2, step is the same; Measure basic point 6 distance perpendicular to the top airfoil 5 of vehicle frame 2 and the plane of the outside of belly 7 to check point 4 place; Finally calculate the space length between basic point 6 to check point 4, and the space length in design drawing between basic point 6 to check point 4 contrasts, and can know that whether the position protecting solar or lunar halo 1 is correct.In order to avoid measuring error is comparatively large, multiple point need be measured and contrast.
To the testing process between the check point 8 of engine assembly 3 and basic point 6 and above-mentioned steps similar.
The program is simple to operate, but complex steps, and metrical error is comparatively large, and cumulative errors can be larger, is particularly with angled dimensional error of sapce larger.
In prior art, the second detection mode is that three-coordinates measuring machine is measured, and is exactly testing staff by three-dimensional tester to protecting solar or lunar halo position and engine location detects.Concrete operation method is as follows:
First true origin is demarcated.
Then detected parts being put into monitor station, once determine, just cannot move, otherwise measurement data is invalid in parts position.The position of tested parts is put very crucial, determines precision and the difficulty of dimensional measurement.If position is put bad, cylindricity, PIaneness-measuring error are large, and even these sizes cannot be measured.
Then measurement data.This three-coordinates measuring machine can pass through slide in X, Y, Z tri-directions, and its probe can rotate arbitrarily in surface level.Probe is moved to tested point position and carry out data induction record, check point coordinate only needs measurement point, and measuring straight line generally needs measurement 3 points, and measuring circularity generally needs measurement 4 points, and measurement plane degree generally needs measurement 5 points.
Final data process.Convert responded to point to point with coordinate system, coordinate origin, for demarcating initial point, is then measured by survey instrument, just can be calculated measured size.
Program accuracy of detection is higher, but its accuracy of detection is by the impact of measured piece putting position, and circular hole, angle, flatness equidimension detecting step are comparatively loaded down with trivial details, need to test multiple coordinate points; Three-coordinates measuring machine cost is higher, detects resource less, needs professional operator to measure.If utilize three-coordinates measuring machine to measure the vehicle frame 2 in Fig. 1 and the relative position protected between solar or lunar halo 1, engine assembly 3, the car load chassis assembled is needed to move on monitor station, limit by the size of measuring instrument own, cannot measure for large scale chassis such as trucies, and the detection of these scale coordinate is comparatively loaded down with trivial details, measurement efficiency is low, and equipment cost is high, not easily generally implements.
