Description
Technical field
The present invention relates to a kind of cubing of automobile component, especially a kind of stability is better, the flexible inspection device for front portion of automobile that service precision is higher.
Background technology
Each parts of automobile and car load are reach desirable machining precision, various cubing is mostly needed to detect, therefore various cubing is simple, quick, the effective field test instrument of the one that the car load factories such as automobile take all supply auxiliary equipments in product development and manufacture process, check and verify one of indispensable process unit whether product is qualified, main in order to check the scale error between product and prototype, and judge that whether parts are qualified fast.
In automobile production process, due to the factor of fixture, auto parts and components, process equipment, personnel's experience and skilled operation degree etc., cause automobile making quality unstable, particularly automotive front, less stable, fit-up gap profile standard-required is very strict.And automotive front also overcomes the position of being strict with manufacturer and carrying out controlling just, directly affect the profile of automobile.
The development of process of industrialization, produces in enormous quantities and production line balance constantly occurs, original omnipotent measuring method, as slide calliper rule, milscale, platform measuring technology etc., can not adapt to the requirement of production efficiency.For the detection of automotive front, generally adopt bumper as trial assembly at present, and a bumper cost is generally between 300-500 unit, different according to vehicle, one-period will change front bumper, the wearing and tearing of front bumper support are relatively more serious, after wearing and tearing, can reduce the accuracy of front bumper, repeatedly trial assembly, cause front bumper to be out of shape serious, affect the quality of trial assembly, finally can affect the qualification rate that once rolls off the production line.
Patent Office of the People's Republic of China has announced a CN202074908U patent on Dec 4th, 2011, name is called a kind of white vehicle body lower part detecting tool, comprise framework, front web joint, middle web joint, rear web joint, front detection block, front test pin, middle test pin and U-shaped detection block, front web joint, middle web joint and rear web joint are welded in the front portion of framework, middle part and rear positions respectively, front detection block and front web joint removably connect, middle test pin and middle web joint removably connect, U-shaped detection block and rear web joint removably connect, and detect on block before front test pin is fixed on.But this cubing is used for detecting the bottom of body in white, can not test to automotive front.
Summary of the invention
The invention solves in the inspection of automotive front in prior art, the defect that inspection stability is lower, testing accuracy is lower, provides a kind of flexible inspection device for front portion of automobile, and by fixture and the combination of detection block, detect good stability, testing accuracy is high.
This invention also solves in prior art and use bumper as trial assembly, the defect that serious wear, cost are higher, provide a kind of flexible inspection device for front portion of automobile, directly for automotive front, cubing wearing and tearing are little, and cost is lower.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flexible inspection device for front portion of automobile, comprises the support of intermediate symmetry and intermediate symmetry and is arranged at locating device, locking device and detachable fixing combined type headlight Surface inspection block on support and lateral aperture pick-up unit; Locating device is pin locating device, and locking device is dead point locking device, and headlight Surface inspection block has arc detection faces, and the arcwall face that after the combination of headlight Surface inspection block, each arc detection faces is formed and the surface of headlight match.Support is installed various pick-up unit and locating device and locking device, support is fixed on automotive front by locating device and locking device, accurate positioning, fixing-stable, improves the stability and precision that detect; Locating device use pin directly can be positioned two pilot holes on the vehicle body crossbeam of automotive front, and vehicle body beam deformation is little, and the position of two pilot holes is accurate, and behind pin location, the location comparison of support is accurate; Headlight Surface inspection block adopts combined type to improve the laminating degree with headlight profile, improve the degree of accuracy detected, gap can be reserved between combination after each headlight Surface inspection block combination, this gap can adjust the laminating degree between the arcwall face after combination and headlight profile, to a certain degree can contain the reasonable error of headlight profile; Locking device adopts dead point locking device, locking device self-relaxation can be prevented, in locking process, through the position at dead point, the moment that coupling mechanism force produces changes, the effect being subject to external force can produce larger coupling mechanism force, needs under the effect of external force, cross dead point and just can open locking device, lock more reliable; Each pick-up unit employing is detachable to be fixedly connected with support, and the size model of each monitoring block of convenient adjustment, realizes flexible detection, complete the detection to different model product, possess one-to-many, take up room little, that waste of material is few feature.
