Description
Technical Field
The invention discloses a key assembly dimension checking fixture with a matching function for a rear headlamp of a car, belongs to the technical field of the key assembly dimension checking fixture for the rear headlamp of the car, and particularly discloses the key assembly dimension checking fixture with the matching function for the rear headlamp and a detection method.
Background
The dimensional precision of the gap surface difference between the exterior parts has great influence on the appearance quality of the car, and is the core content of the appearance quality evaluation standard. In order to ensure the gap surface difference between the exterior parts, the welding geometric dimension precision and the stability of the white car body of the car need to be measured and controlled. A Check Gauge (Check Gauge) for welding key assembly dimensions is a common tool for measuring the accuracy and stability of welding geometric dimensions of a body in white. For example, in order to ensure the clearance surface difference between the rear headlamp and the environmental part (including the side wall, the back door, the rear bumper and the like), a key assembly dimension gauge of the rear headlamp needs to be designed and manufactured to measure the welding geometric dimension precision and stability of the rear headlamp environmental part. In general, a standard rear headlamp is designed and manufactured, the back surface of the standard rear headlamp has the same positioning and mounting mode as the real object of the rear headlamp, but the front surface of the headlamp is replaced by an extending surface of an environment part, and the view is shown in figure 1; and then, after the key assembly dimension gauge of the rear headlamp simulates a real object lamp to be assembled on a white vehicle body, the welding geometric dimension precision and stability of the relevant parts (the rear part of the side wall and the tail lamp base plate) of the side wall assembly can be evaluated by measuring the clearance surface difference with an environment part, and the clearance surface difference and stability of the relevant parts of the back door can be evaluated. According to the technical scheme, three groups of associated geometric dimensions with matching relations need to be regulated and controlled: firstly, the size precision of a side wall assembly around the rear headlamp is improved; secondly, the opening degree and the installation posture of the back door; thirdly, matching segment difference of boundary lines among the parts; the prior art is respectively managed and controlled: the method comprises the steps that a rear headlamp key assembly size gauge is used for detecting the clearance surface difference of environmental parts (a side wall assembly and a rear back door part), a rear back door opening gauge is used for detecting the opening and the posture of the rear back door, and the section difference of a boundary between parts is measured through assembling object parts. The key assembly size of headlight examines utensil and does not have the matching function who examines the utensil with back door opening, only can match with the back door material object, because the size of back door material object has great error and stability can not be controlled, so the mutual matching condition that has the geometric dimensions of matching relation that above-mentioned three groups are correlated with still need indirect evaluation with the help of means such as 3D measurement after using to examine the utensil, the evaluation means of this kind of matching relation is not directly perceived, with high costs, and is inefficient, and the precision is low, and simultaneously, it still has following defect: the technical scheme is that the system is an independent subsystem, and can solve the problem of welding size precision measurement of an environment part related to a rear headlamp, namely the problem of measurement of the difference of a clearance surface between the rear headlamp and the environment part, but because the system is an independent non-relevant measurement and evaluation mode, the evaluation mode cannot independently solve the problem of deviation caused by the influence of the subsystem under the assembly environment of the whole vehicle, and three groups of related geometric sizes with matching relations of the difference of the clearance surfaces of the rear headlamp and the environment part need to be managed and controlled: firstly, the size precision of the side wall assembly around the rear headlamp. The opening degree and the installation posture of the back door. And thirdly, the matching section difference of the boundary between the parts, specifically, the technical scheme can only solve the first problem, namely the dimensional accuracy of a side wall assembly at the periphery of the rear headlamp, can not solve the two following problems, can not evaluate the influence of the opening and the installation posture of the back door on the gap surface difference of the related part, and can not evaluate the matching section difference of the boundary between the parts of the rear headlamp environment.

The key assembly dimension checking fixture of the rear headlamp 13 can be independently installed on a vehicle body, the ridge on the section difference matching surface on the checking fixture is used as a datum line, and the parting line (the parting line of the back door 5 and the side wall assembly and the parting line of the back door 5 and the rear bumper 6) on the actual part and the staggered joint distance of the ridge on the checking fixture are compared by using a small steel plate ruler. The tolerance zone of the section difference is specified in the finished automobile appearance clearance surface difference specification file, whether the measured value falls in the tolerance zone or not is judged according to the actual measurement result, if the measured value falls in the tolerance zone, the installation precision of the rear bumper 6 and the back door 5 is judged to be qualified, and if the measured value falls out of the tolerance zone, the installation precision of the rear bumper 6 and the back door 5 is judged to be unqualified. 3) The opening degree and the installation attitude of the back door 5 are measured.

The theoretical value is subtracted from the actual measurement value to obtain a compensation value (calibration value) of the surface difference and the gap, the compensation value is considered when measuring the welding dimension precision (the surface difference and the gap) of the side wall assembly around the back headlight 13 in the measuring method 1), and the actual measurement value is calibrated by using the compensation value, so that the gap surface difference of the matching area of the back door 5 and the back headlight 13 can be accurately judged.

But the results are found: the detection surface of the backdoor opening gauge 3 is 0.5mm lower than the clearance surface difference matching surface (taking the clearance surface as a comparison reference surface) of the key assembly gauge of the headlights 13. Then the face difference compensation value is obtained and recorded as: -0.5 mm. 2) And (5) detaching the backdoor opening detection tool 3. 3) The back door 5 part is installed, a back door clearance detection reference surface on the back headlamp 13 key assembly gauge is used as a reference, and a clearance surface difference gauge is used for detecting the actually measured surface difference between the gauge and the back door 5 part, wherein the actually measured value is-1.5 mm, namely, the back door 5 part is lower than the back door clearance detection reference surface on the back headlamp 13 key assembly gauge by-1.5 mm. In this case, the influence of the offset value of-0.5 mm on the measurement results is taken into account. The compensation value-0.5 mm means that: due to the influence of the welding precision of the vehicle body, the mounting points (mounting holes and mounting surfaces) of the parts of the back door 5 on the vehicle body have precision deviation, so that the parts of the back door 5 on the vehicle body are always lower than a back door clearance detection reference surface on a key assembly gauge of the back headlamp 13 by 0.5mm, and the tolerance of-0.5 mm is brought by the welding precision of the vehicle body and is not brought by the parts of the back door 5. Therefore, the error value M of the back door 5 part at the measuring position is obtained by subtracting a compensation value of-0.5 mm from the actually measured surface difference value of-1.5 mm between the key assembly gauge of the back headlamp 13 and the back door 5 part by using the clearance surface difference gauge. Namely: m-1.5- (-0.5) -1 (mm).
