Abstract
A deflection adjusting method for camber beam location of a car roof installation and welding clamp is characterized in that a circular arc deflection curve is obtained by computer-aided design (CAD) drawing based on the known peak of the car roof center and zero points of both ends, a plurality of datum points are arranged on the curve, the plurality of datum points are connected and a deflection line used for adjusting is obtained by on-spot line drawing, and then the height of the other car roof camber beam location supports is adjusted with the drawn line as the datum. The deflection adjusting method for camber beam location of the car roof installation and welding clamp has the advantages that the plurality of datum points are arranged on an ideal deflection curve segment of the CAD three-point drawn circular arc, and the plurality of datum points are connected and the deflection line used for adjusting is obtained by on-spot line drawing. The camber beam location supports required to be adjusted are adjusted to the position of the drawn line and further the height is set according to the line so as to achieve fast and accurate adjusting of deflection of scores of car roof camber beam location supports.
Description
Technical field
The invention belongs to trolley coach manufacturing technology field, relate to stainless steel roof assembly-welding anchor clamps camber beam location amount of deflection method of adjustment.
Background technology
Tens carlines of trolley coach stainless steel roof prefabricated amount of deflection that raises up in assembly welding positioning supports process; Make it to synthesize the vehicle that integral body has the epirelief amount of deflection with other big parts; Carrying operation gravitate recovery level, prevention is carried operation gravitate car body and is stayed.At present; The camber beam of roof assembly-welding anchor clamps location amount of deflection press the orthodox practice adjustment, with the numerical value mode of arbitrarily successively decreasing of mind-set two ends therefrom amount of deflection is set, and the amount of deflection and the actural deflection curve that cause the carline of tens of up to adjust are not inconsistent; Each strong point error is very big, needs repeatedly adjustment repeatedly.
Summary of the invention
The purpose of this invention is to provide a kind of roof assembly-welding anchor clamps camber beam and locate the amount of deflection method of adjustment, inaccurate, the low problem of efficient of the amount of deflection adjustment that the carline that solution roof assembly-welding anchor clamps up is tens is located, the realization camber beam is located quick, the accurately adjustment of amount of deflection.
For realizing above-mentioned purpose; The present invention provides a kind of roof assembly-welding anchor clamps camber beam location amount of deflection method of adjustment; It is characterized in that: obtain a circular arc sag curve through the CAD drawing zero point according to known roof center peak and two ends; Some datum marks being set on this curve, connecting the amount of deflection line that some datum marks and on-the-spot backguy obtain an adjustment usefulness, is that benchmark is regulated height with the backguy with all the other carline positioning supports again.
Good effect of the present invention is: on the desirable sag curve section of CAD three strokes and dots circular arcs, some datum marks are set, connect the amount of deflection line that some datum marks and on-the-spot backguy obtain an adjustment usefulness.The camber beam positioning supports of needs adjustment adjusted on the backguy position and by line height is set, the carline positioning supports amount of deflection that realizes tens of up fast, accurately adjustment.
Description of drawings
Accompanying drawing is a roof assembly-welding anchor clamps camber beam location amount of deflection adjustment schematic diagram.
The specific embodiment
With reference to accompanying drawing, known roof is given the peak 1 that centers, and connects roof left end 0. 2 and roof right-hand member 0. 3, draws to connect horizontal line 4.Application of CAD drawing function 3 circular arcs that draw obtain a circle arc curve section on 2 points, 1 point, 3, and this curved section promptly is the true sag curve 5 of roof.On the true sag curve 5 of roof some datum marks are set.As: the right datum mark 6, the right datum mark 7, left side datum mark 8, left side datum mark 9 are set, connect some datum marks and on-the-spot backguy formation and the true sag curve 5 approximate backguys 10 that overlap of roof.Measure the deflection data that centre-height 11 is exactly the roof center, measuring each datum mark height of right-hand member and left end is exactly the deflection data of each datum of roof.Again with all the other carline positioning supports 12 (actual quantity surpass diagram) adjust to approximate backguy 10 positions that overlap of sag curve on, and height is set by line, realize that with this carline location amount of deflection fast, accurately adjust.
