According to the assistance device and the method for detecting flatness of the vehicle door by adjusting the magnets, whether matching of four doors welded on a white vehicle meets an approval standard of welding of a white vehicle body can be accurately judged by adjusting a height difference of the two magnets, so that remaking of the whole vehicle and corresponding costs due to checking errors are reduced, and labor intensity is reduced; the possibility of misjudgments is reduced while accuracy of the appearance of the white vehicle body is detected, and unreasonable remaking is reduced.
Description
Technical field
The present invention relates to a kind ofly for automobile manufacturing field four accessories whether assembling is qualified of check that are welded, specifically, relate to a kind of adjustable suction iron car door Pingdu and detect accessory and detection method thereof.
Background technology
The finishing operation that weld car workshop is adjusted on line is to adjust four-door two-lid and beater or beat-up station, checks out full up foot and hands over after car standard, the Painting Shop of being allowed for access checker.Because parts are not installed, fixedly body in white state, therefore can only utilize detection accessory to detect, but these accessories is more coarse often, very large on the Qualification impact of the body in white that is welded.For example, detect four see outdoors while mating in the workshop that is welded, due to door lock not being installed, therefore four assemblies are relaxed states on body in white, cannot direct-detection.As shown in Figure 1, the accessory that detection is at present four is generally the suction iron of a monoblock, this is inhaled iron and inhales in the cooperation of front/rear door assembly and Qianmen assembly door lock intersection, simulate the whole vehicle state that door lock is installed, by judgement, inhale iron and inhale four match condition after putting down, the situation that reflects four couplings of car load, and by this, put to detect other check points and whether meet in margin tolerance.If it is flat by front and back door-inhale in latch position to inhale iron, this place's Pingdu reality one is decided to be 0mm so, but product is in design process, consider the attitude of car load and the situation attractive in appearance of car load, the theoretical Pingdu that can define is generally [0,1.0] mm, and the suction iron that detects accessory coordinates front/rear door with gate lock of front gate intersection and forces to inhale flat (making this place's Pingdu is 0mm), the measuring error of other measurement point that can cause increases, accuracy and authority that impact detects.Easily appear in detected underproof body in white, some is to meet when door lock place check point satisfied (0,1.0] within the scope of mm, other check points also can be qualified body in white, in fact, the body in white of these erroneous judgements meets product design and requires, and the body in white of these " qualified " can because detect accessory unreasonablely cause a large amount of doing over again, increased labour intensity.
Summary of the invention
The object of the invention is to propose a kind of reasonable, accurate adjustable suction iron car door Pingdu and detect accessory and detection method thereof, with when accurately detecting body in white outward appearance precision, reduce the possibility of erroneous judgement, thereby reduce irrational doing over again.
Adjustable suction iron car door Pingdu of the present invention detects accessory and comprises a frame-type shell and fixed support, is provided with side by side two and inhales iron in described shell, and described every block of suction iron is equipped with a threaded hole; Described fixed support comprises connecting link, and the two ends of described connecting link are equipped with sleeve, and described fixed support is connected with two blocks of suction iron respectively by the bolt through sleeve screw-in suction iron threaded hole.
The detection method that above-mentioned adjustable suction iron car door Pingdu detects accessory is as follows:
Utilize bolt adjustment to inhale the height of iron, make two bottom surfaces of inhaling iron concordant, then adjustable suction iron car door Pingdu is detected to accessory and be adsorbed on the cooperation of body in white front/rear door and gate lock of front gate intersection, making the Pingdu of front/rear door at latch position place is 0mm, and then measure other check point, if it is qualified that other check point detects, body in white meets the car standard of handing over; If it is defective that other check point detects, utilize bolt within the scope of predetermined difference in height, to adjust two differences in height of inhaling the bottom surface of iron, and then measure other check point, if other check point is in the setting range of inhaling iron or detection is not for conforming to lattice point, this body in white is defective car so, need to do over again.
Further, for convenience of accurately controlling two differences in height of inhaling the bottom surface of iron, suction iron car door Pingdu that this is adjustable detects accessory and also comprises pad, and described pad is provided with the breach that width is greater than the diameter of bolt and is less than sleeve outer diameter, and described pad is installed between the top of sleeve and the nut of bolt.By inserting or extract out or changing different-thickness pad, and then screw the mode of bolt, adjust the height of inhaling iron, thereby adjust two differences in height of inhaling the bottom surface of iron.Aforesaid way is in course of adjustment without measure two differences in height of inhaling the bottom surface of iron with special measurement instrument, has reduced the dependence to operator's proficiency and working attitude, can guarantee precision, and adjust very convenient simultaneously.Above-mentioned pad can have a plurality of, and the thickness of described pad increases progressively.
Further, inhale iron spacing for two and cross conference impact Pingdu judgement at latch position place to front/rear door, for reducing described two gaps of inhaling between iron of the excessive impact on detection of two suction iron spacing, be less than 0.2mm.
Further, between described suction iron and shell, be provided with lining, described lining is fixed by interference fit and shell, the inner side of described lining is provided with protuberance, the outside of described suction iron is provided with the groove coordinating with described protuberance, and the bottom of described groove extends to inhales iron bottom surface, the top closure of groove.Lining not only can be avoided inhaling the direct friction between iron and shell and the suction iron wearing and tearing that cause, can also prevent from inhaling the iron shell that drops out.
Further, for convenience of gripping and operation, described fixed support also comprises a handle being connected with connecting link by pole.
The present invention, by the difference in height that regulates two to inhale iron, accurately distinguishes in the body in white that is welded, whether four couplings meet the white car vehicle body criterion of acceptability that is welded, thereby reduced, the car load causing because of verify error is done over again and corresponding cost, has reduced labour intensity.
