Technical field
The present invention relates to a kind of car body three-dimensional dimension detection method, be applied to the detection of car body three-dimensional dimension in EMU manufacture process, whether assessment car body meets the accuracy requirement of follow-up assembling and online operation.
Background technology
The vehicle body of EMU and each member profile complexity, need in measuring process to extract a large amount of vehicle body three-dimensional dimension data (such as car body deflection value, vehicle body breadth extreme and half width values etc.), the testing tool of some routines as tape measure, shrinkage-rule, stadimeter etc. because of detect the problems such as accessibility cannot meet EMU car body produce in quick and high-precision measurement demand.
Summary of the invention
The present invention discloses a kind of car body three-dimensional dimension detection method, and object is every physical dimension such as length after detecting Rail car manufacture completes, and contrast theoretical size and tolerance, whether assessment vehicle meets follow-up assembling and Operational requirements.
For achieving the above object, the invention provides a kind of EMU car body three-dimensional dimension detection method, it is characterized in that comprising the following steps:
1, according to vehicle detection corner, auxiliary mould is made, with the measurement coordinating total powerstation to complete body contour size; Specifically comprise vehicle side bar width detection auxiliary mould, length of wagon detects auxiliary mould, height of car detects auxiliary mould, detection reference auxiliary mould;
2, vehicle to be measured one, "A" end of car diagonal position sets up base stations detected, and the region that can observe two base stations arranges 2 reference point targets, determines measuring basis, uses single device to change station and detects, during detection with one of them reference point for initial point C
1, another reference point is C
2, the line of 2 sets up right-handed coordinate system as X-axis positive dirction, exports the coordinate figure of each check point in this surving coordinate system;
3, using car body "A" end of car sleeper beam central point of hole as X-axis, Y axis datum point, using car body two ends hitch bore centre-height mean value as altitude datum, set up right hand rectangular coordinate system O using the line of car body sleeper beam central point as X-axis positive dirction

In figure: 1 is tooling base, 2 is frock cross-brace, and 3 is rivets, and 4 is reflective stickers, and 5 is processing pedestal, and 6 is height detection tool pedestal, and 7 is hitch, and 8 is overall processing pedestal, and 9 is base stations detected.
Embodiment
1, design detects auxiliary mould
With reference to Fig. 1-4, some check point positions are special, and total powerstation cannot be used directly to observe, and need design frock to assist detection.Detect auxiliary mould and comprise vehicle side bar width detection auxiliary mould, length of wagon detection auxiliary mould, height of car detection auxiliary mould, detection reference auxiliary mould.
2, data acquisition is detected
With reference to Fig. 5, according to vehicle detection figure, coordinate and detect auxiliary mould, vehicle to be measured one, "A" end of car diagonal position sets up base stations detected, use single device to change station and detect.
2.1 with reference to Fig. 4, utilize detection reference auxiliary mould at two base stations detected all visible location setting detection references, coordinate system public translation point when changing station as total powerstation;
2.2, with reference to Fig. 1, utilize vehicle side bar width auxiliary detection frock to be stuck in detection vehicle side bar carrying out side bar width;
2.3 with reference to Fig. 2, utilizes length of wagon to detect auxiliary mould and abuts in the measurement that length of wagon is carried out at vehicle two ends;
2.4 with reference to Fig. 3, utilizes height of car to detect auxiliary mould and hangs over below the hitch beam of vehicle two ends, assist and carry out the detection of hitch depth of beam.
During detection with one of them reference point for initial point C
1, another reference point is C
2, the line of 2 sets up right-handed coordinate system as X-axis positive dirction, exports the coordinate figure of each check point in this surving coordinate system.
3, data processing and output is detected
Check point coordinate input data processor (this program utilize Microsoft Excel to add automatic process and output that work formula carries out data) that 2nd step is obtained, sequential operation Main Basis Plane Rotation principle, calculate each check point XY axial coordinate value, be specially:
x'=(x-x
0)*cos(n)+(y-y
0)*sin(n)；y'=-(x-x
0)*sin(n)+(y-y
0)*cos(n)。
X, y are surving coordinate value; X', y' plane conversion rear vehicle coordinate figure; x
0, y
0for the difference of vehicle axis system initial point and surving coordinate system initial point XY axial coordinate value; N is the anglec of rotation between two coordinate systems.
Concrete operation process is as follows:
With reference to Fig. 6,3.1 set up vehicle axis system: utilize bogie pivot center line position 4 measurement point coordinate figures (using vehicle side bar width detection auxiliary mould to record), calculate the center point coordinate value of car body both sides bogie pivot center line measurement point, again with the central point of car body one end for initial point, the line of itself and other end central point is X-axis positive dirction, sets up rectangular coordinate system (vehicle axis system);
3.2 utilize above-mentioned Plane Rotation formula to complete the coordinate figure conversion work of all measurement points between surving coordinate system and vehicle axis system;
The X-axis of 3.3 now each point coordinate is length of wagon direction, Y-axis is vehicle-body width direction, Z value is short transverse, deducts each point auxiliary mould size and can draw true vehicle body coordinate;
Each check point physical size of 3.4 calculating drawing requirements, contrasts with theoretical size (tolerance), reports to the police if any overproof corner display red font.
