Abstract
The utility model discloses a horizontal height difference correction system of a laser projection type automobile four-wheel aligner lifting rack. The system aims at solving the problem that the horizontal height difference between the automobile four-wheel aligner lifting rack and the wheel contact point cannot be fast and correctly inspected and corrected. The system comprises a laser demarcation device (1) and a staff gauge (2). The detection system can be used for fast inspecting and correcting the detection points of a plurality of four-wheel aligner lifting racks.
Description
Technical field
The present invention relates to a kind of checkout equipment of auto industry field, in particular, it relates to a kind of laser-projection-type vehicle four-wheel position finder lifting frame difference in level corrective system.
Background technology
Vehicle handling stability and roadholding are to be guaranteed by the Proper Match of vehicle wheel alignment parameter, any one misalignment of parameter just can cause automobile loss of control stability and straight-line travelling ability, accelerate tire wear, oil consumption is risen, degradation problem under security.
Wheel alignment meter is the most important checkout equipment of check wheel alignment.The recoverable amount of present national wheel alignment meter reaches more than 20 ten thousand, and the speed with annual 30% is increasing progressively, no matter yet be its production run or its use procedure, at present all can not carry out system to the performance of wheel alignment meter and effectively check, can't guarantee the accuracy of detection of wheel alignment meter itself.
The vehicle four-wheel position finder lifting frame is the wheel alignment meter main accessories.
Wheel alignment meter is indirectly to measure by mathematical model to the measurement of stub kingpin castor angle and kingpin inclination, stub kingpin castor angle and kingpin inclination are the function of Camber angle in model, and wheel angle sensor is take plane that four-wheel position finder lifting frame and each ground contact point of the wheel that parks a car consisted of as measuring basis.Therefore, be to guarantee the accuracy of four-wheel position finder measurement result, must be to the correction of testing of vehicle four-wheel position finder lifting frame difference in level.
Summary of the invention
The utlity model has the function that vehicle four-wheel position finder lifting frame and each contact point difference in level of automotive wheel are tested and proofreaied and correct, and can read simultaneously take laser projection plane as benchmark each test point height on four scales, the accuracy of corrective system can be satisfied national quality superintendent office and manufacturer the quality of vehicle four-wheel position finder lifting frame is carried out on the spot the requirement of calibrating fast higher than the requirement of national standard to vehicle four-wheel position finder lifting frame and each contact point difference in level of automotive wheel.
Consult Fig. 1 to Fig. 3, for solving the problems of the technologies described above, the utility model adopts following technical scheme to be achieved.Laser-projection-type vehicle four-wheel position finder lifting frame difference in level corrective system provided by the utility model includes laser level and scale.
Laser level is placed on smooth ground, and scale is placed on the test point of vehicle four-wheel position finder lifting frame.
The accuracy of measurement of the laser level described in technical scheme is not less than 1mm in the 5m scope.
Scale described in technical scheme is mainly formed by a thick rectangular steel plates and an elongate steel sheet vertical welding, the equidistant scale of scale elongate steel sheet side processing, the verticality of the bottom surface of the graduated plane of elongate steel sheet band and thick rectangular steel plates is not more than 0.1mm, and the bottom surface length of side of thick rectangular steel plates is not less than 200mm.
The beneficial effects of the utility model are:
(1) adopt laser level to produce the horizontal laser light projection plane as benchmark, projection on the scale of a plurality of measurement points simultaneously, and carry out simultaneously the adjustment of four-wheel position finder lifting frame difference in level according to projection place scale, assay is accurate, the adjustment time is short, and checkability is high.
(2) critical part scale of the present utility model adopts the standard steel to process, and at first, standard steel output is large, and the machining operation is few, and production cost is lower; In addition, as the important accessory of surveying instrument, adopt the standard steel to have certain intensity, can be indeformable in long-term the use, guarantee the precision of measurement, can satisfy national standard to the requirement of accuracy of detection.
