Study On The Form A Deviation Of The Automobile Bodywork Examination Instrument

Although automobile testing technology has enormously improved than before, its development isn't balance. I ts some aspects which people think of unimportant have been ignored. For instance, The form a deviation of the automobile bodywork examination instrument has vacancy at internal or overseas countries. This detecting instrument is designed aiming at the status. The form a deviation of the automobile bodywork examination instrument difference of the paper has the characteristics of speediness and nicety. We can operate the scale to choose the first point on the body as long as there are definite distances between parking place and detecting instrument. Then press the RESET button, go round and round the scale to stated angles, make laser at another point, we can read the altitude difference between two points. The equipment has many excellences such as convenient operation, small cubage, little wasting power, etc. It is able to adapt requires of pint-sized and medium-sized checkpoints.The central contents of this paper:1 .theory analysis of systemWe prove the study on The form a deviation of the automobilebodywork examination instrument is not only essential but also feasible from theoretically speaking, through analyzing the reason of appearing a deviation of the automobile bodywork and the influence of body's lurch onthe using capability of automobile.2.machine design of systemWe designed secure flexible convenient machine system which can rapidly and exactly detect according to circumstance, temperature, humidity and the require of checkpoints .3.circuit control of systemIn this part, we designed the circuit diagram of testing system and control circuit of reset and scale's going up or down.4.demarcating of system and test-driveWe validate the system precision can satisfy testing require through the demarcating of system. At the same time, through testing the actual automobile, we testify the system has higher dependability and reliability.5.experiment analysisWe educed the testing gist through plentiful experiment and analyzing experiment data.The innovative side of the paper:The research makes the use of the forerunner's laser range the finder under the condition of not the get in the touch with, measure the distance of point and point accurate and fast, make use of the triangle relation to compute t he a c arriage t he 1 ength. m ake u se o f t he c amera tod eliver t he anomaly face( the car head and the car tail) of portrait in the calculator, using the calculator processing the portrait is accurate to find out the middle point of the car head and tail, turn complicated problem in brief. Finally accurate, objective, compute a deviation Cape of a bodywork form fastly.Avoided the subjective error margin that the artificial diagraph appear currently, reduce the error, guarantee the measured accuracy.The detecting instrument of automobile altitude difference can rapidly test a deviation of the automobile bodywork examination instrument symmetrical points in the state of un-touching body. It can not only directly...
