Also in conjunction with the accompanying drawings measuring method of the present utility model is described in detail below by specific embodiment:
As shown in Figure 6, on four location piers, designed drawing strickle guide detection and localization platform A, B, C, D respectively, be used for side frame guide is positioned and each size of drawing strickle guide is measured.Displacement transducer is installed, line slideway, locating device etc. on the monitor station.Along continuous straight runs (being the bogie side frame direction) has been installed differential displacement sensor AX1, a BX1, CX1, DX1 (range is 40mm), sensor adopts cylinder to drive and measures, two differential displacement sensors (range is respectively 60mm) AY1, AY2, BY1, BY2, CY1, CY2, DY1, DY2 also have been installed in vertical direction, have driven operation by cylinder and measure.
The monitor station bottom is connected with the column table top by line slideway, monitor station can move (changeing 8 serial bogies to adapt to) at column table top along continuous straight runs by air cylinder driven, and the monitor station side has the locating device by air cylinder driven to carry out the accurate location that monitor station moves.Constitute the monitor station slide device by line slideway and driving cylinder, drive monitor station and support apart from the position that falls of bogie to adapt to disalignment.
When measuring, measure length dimension between each monitor station centrepin with micrometer inside caliper, and the monitor station sensor is installed the length of each daylight opening DLO decentering pin, can calculate each monitor station centrepin and the coordinate of theoretical center in plane coordinate system XY, obtain the coordinate relation between each monitor station.
Three displacement transducers are arranged, a horizontal direction displacement transducer and two vertical direction displacement transducers on each monitor station position.During detection, sensor goes out medial surface of side frame guide and two distance of lateral distance monitor station respective mesa up and down, can calculate the coordinate of drawing strickle guide center under monitor station coordinate system XnYn (n is the monitor station numbering) like this, according to relation between coordinate system XnYn and the XY and angle modification, can calculate each coordinate figure of drawing strickle guide center under XY under the same coordinate.Thereby can calculate the key parameter of drawing strickle guide diagonal line and centre distance.
Concrete computing method are as follows:
The monitor station parameter:
Measure four length dimensions between the monitor station centrepin with micrometer inside caliper, comprise AB, AC, AD, BC, six length of BD, CD, can determine the coordinate of four monitor station centrepins on plane coordinate system XY by these six sizes.Method is as follows:
If above-mentioned six length dimensions are s_ab, s_ac, s_ad, s_bc, s_bd, s_cd.
Suppose that the C platform is a true origin, i.e. Xc=0, Yc=0; If the CD direction is the X-axis positive dirction, Xd=s_cd then, Yd=0.
Calculating can get A platform and B platform coordinate:
Xa＝s_ac*(s_ac*s_ac+s_cd*s_cd-s_ad*s_ad)/(2*s_ac*s_cd)；
Ya＝s_ac*sin(arcos(s_ac*s_ac+s_cd*s_cd-s_ad*s_ad)/(2*s_ac*s_cd))；
Xb＝s_cd-s_bd*(s_cd*s_cd+s_bd*s_bd-s_bc*s_bc)/(2*s_cd*s_bd)；
Yb＝s_bd*sin(arccos(s_cd*s_cd+s_bd*s_bd-s_bc*s_bc)/(2*s_cd*s_bd))。
Because depth of parallelism control accuracy was higher when four monitor stations were made, so be that the single monitor station coordinate system (XaYa, XbYb, XcYc, XdYd) of true origin can think equidirectional with coordinate system XY with the monitor station centrepin.
Also measured the distance between three sensors installation table tops of monitor station and the centrepin simultaneously, AX1 as shown in Figure 6, AY1, AY2 etc.Can calculate the coordinate of each monitor station theoretical center on coordinate system XY like this.The theoretical center coordinate is as follows:
Xoa＝(AX2-AX1)/2+Xa；Yoa＝(AY1-AY2)/2+Ya；
Xob＝(BX2-BX1)/2+Xb；Yob＝(BY1-BY2)/2+Yb；
Xoc＝(CX2-CX1)/2+Xc；Yoc＝(CY1-CY2)/2+Yc；
Xod＝(DX2-DX1)/2+Xd；Yod＝(DY1-DY2)/2+Yd。
By monitor station theoretical center coordinate, can calculate the various sizes of monitor station theoretical center, comprise parameters such as monitor station center diagonal L1, L2.
L1＝sqrt((Xoa-Xod)*(Xoa-Xod)+(Yoa-Yod)*(Yoa-Yod))；
L2＝sqrt((Xob-Xoc)*(Xob-Xoc)+(Yob-Yoc)*(Yob-Yoc))。
Measure and calculate:
During measurement, the horizontal direction displacement transducer detects the distance of two vertical outer faces of side frame guide medial surface distance detecting platform, and the vertical direction displacement transducer then detects the distance of drawing strickle guide two horizontal direction medial surfaces of lateral distance monitor station about in the of two.
But so only also can not calculate the center of drawing strickle guide A by these four values on horizontal direction (x direction) and the vertical direction (y direction), because also need to consider the angle modification of bogie side frame inclination, promptly need accurately to calculate the coordinate position of drawing strickle guide A and drawing strickle guide B with the data of B monitor station.Concrete outcome is as follows:
The measured value of definition A platform and B platform sensor is x1a, x2a, y1a, y2a, x1b, x2b, y1b, y2b;
xa＝(x2a+AX2-x1a-AX1)/2+Xa；
ya1＝(AY1-y1a-AY2+y2a)/2+Ya；
xb＝(x2b+AX2-x1b-AX1)/2+Xb；
yb1＝(AY1-y1b-AY2+y2b)/2+Yb；
ya＝ya1+(dd+(xa-Xa))*(yb1-ya1)/(Xb-Xa+dd*2)；
yb＝yb1-(dd-(xb-Xb))*(yb1-ya1)/(Xb-Xa+dd*2)。
Wherein, xa, ya are the centre coordinate of drawing strickle guide A, and xb, yb are drawing strickle guide B centre coordinate, and dd is the horizontal range that centrepin arrives the vertical direction displacement transducer, and Xa, Ya are the coordinate of A platform centrepin, and Xb, Yb are the coordinate of B platform centrepin.
Equally, can obtain the coordinate of drawing strickle guide C and drawing strickle guide D.Distance relation according between 2 o'clock can calculate parameters such as diagonal line and drawing strickle guide centre distance.
Control system adopts industrial control computer and PLC to control, and is used for bogie normotopia detecting operation is carried out automatically and manually control, and carries out signal indication, interlocking and data management etc.
Bogie normotopia testing process step is: position-crane of selecting bogie type-monitor station to be moved to suitable current type bogie by slide device falls bogie to the position to assembling brace table-input bolster numbering, the left and right side frame numbering, crossbar number-detection-process of the test is full-automatic up and down, preserve and automatically reset after data-test finishes, print result finishes to hang away bogie after the test-stand the test.
Beneficial effect:
The utility model can satisfy lorry maintenance department carries out dissimilar bogies on same equipment normotopia detection test, satisfies technological requirement and maintenance requirement in the lorry maintenance process, has saved cost, and manpower and materials have improved overhaul efficiency.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
