In the related art, the method for calibrating the longitudinal center line of the automobile by the existing calibration equipment comprises the following steps:
(1) and moving the calibration equipment, and aligning the laser emitted from the center of the visual inspection calibration equipment to the center of the front bumper of the automobile. In the method, laser emitted from the center of the calibration equipment is aligned to the center of a front bumper of an automobile through preliminary visual inspection, the longitudinal center plane of the calibration equipment and the longitudinal center plane of the automobile is not in a vertical state, so that laser points reflected by a reflector are deviated to the inner side or the outer side of a laser scale plate, the laser points reflected from the laser scale plates on the two sides of the automobile are difficult to find, and the angle deviation in the left-right direction exists.
(2) And measuring the distance between the calibration equipment and the center of a front bumper or a front wheel of the vehicle by using a measuring tape or a laser range finder. According to the method, the conditions of uneven ground and unadjusted suspension system of a vehicle chassis are ignored, and the axle of a rear wheel of the vehicle and the cross beam of the calibration equipment are not on the same horizontal plane, so that the laser points at two sides are different in emission direction, and the angular deviation in the vertical direction exists.
(3) And respectively installing the two hub clamps on the rear wheels at the two sides of the vehicle, respectively installing a laser into the two hub clamps, and then opening the laser to calibrate. Due to the angular deviation in two directions, the laser points returning from the two sides of the vehicle cannot effectively hit the laser scale plate. In order to enable the laser point to be reflected by the reflector, scales on the laser scale plates on the two sides are equal, and an operator needs to adjust the calibration equipment and the laser for multiple times between the calibration equipment and the rear wheels on the two sides of the automobile, so that the operation process is complex, the learning cost is high, and the efficiency is reduced.
(4) And rotating the laser, and adjusting the irradiation direction of the laser point to irradiate the laser point on the scale plates on two sides of the cross beam of the calibration equipment. And adjusting the calibration equipment until the scales of the laser points on the scale plates on the two sides of the beam are equal. In the method, a certain distance is reserved between the calibration equipment and the rear wheel of the vehicle, so that whether scales on the laser point alignment lasers on the two sides are equal or not is inconvenient to observe, the calibration difficulty is increased, and the time cost is increased.
The following describes a vehicle centering device and a vehicle calibration apparatus according to an embodiment of the present invention in detail with reference to the accompanying drawings.
Referring to fig. 1 to 5, a vehicle centering device according to an embodiment of the present invention includes a base 10, a first laser 20, two wheel alignment members 30, and a linkage mechanism 40.
Specifically, a first laser 20 is provided on the base 10 to emit a laser beam 201 extending in the longitudinal direction of the vehicle, and the first laser 20 may be fixed to the base 10. The two wheel alignment members 30 are disposed on the base 10 and are symmetrical with respect to the laser beam 201, so as to align two wheels 60 that are opposite in the transverse direction of the vehicle, for example, the two wheel alignment members 30 align two front wheels of the vehicle respectively.
The linkage mechanism 40 is disposed between the two wheel alignment members 30, so that the two wheel alignment members move in the same direction or in opposite directions in the lateral direction of the vehicle relative to the base 10. That is, both of the wheel positioning members 30 are movable relative to the base 10, and the two wheel positioning members 30 are moved in a direction in which the two wheel positioning members 30 are moved toward or away from each other in the lateral direction of the vehicle, and the linkage mechanism 40 is connected between the two wheel positioning members 30, and when one wheel positioning member 30 is moved a predetermined distance, the other wheel positioning member 30 is moved the same distance by the linkage action of the linkage mechanism 40, thereby achieving the synchronous movement of the two wheel positioning members 30.
Since the two wheel alignment members 30 are symmetrical with respect to the laser beam 201 emitted by the first laser 20, the laser beam 201 of the first laser 20 is located at the midpoint of the line connecting the two wheel alignment members 30, and when the two wheel alignment members 30 move relative to the base 10, the first laser 20 remains stationary and the position of the laser beam 201 emitted by the first laser 20 remains unchanged, so that when the two wheel alignment members 30 are aligned on the two opposite wheels 60, the midpoint of the line connecting the two wheel alignment members 30 is coincident with the midpoint of the line connecting the two opposite wheels 60, and the laser beam 201 emitted by the first laser 20 is located on the vehicle longitudinal center line.

In the specific positioning, the vehicle centering device can be put to the bottom of the vehicle, and then the sliding plates 301 of the two wheel positioning members 30 are moved transversely along the vehicle, so that the wheel surface positioning members 302 of the two wheel positioning members 30 abut against the wheel surfaces of the wheels 60, and the two wheel side positioning members 303 abut against the outer side surfaces of the wheels 60, so that the two wheel positioning members 30 can be positioned on the two opposite wheels 60, respectively.
In this embodiment, the sliding plate 301 is used to slide, so that the two wheel alignment members 30 can move in opposite directions or in opposite directions, and the distance between the two wheel alignment members 30 is adjusted to be consistent with the width of the two opposite wheels 60, thereby aligning the two opposite wheels 60. In addition, in the wheel positioning element 30, the wheel surface positioning element 302 abuts against the wheel surface of the wheel 60, and the wheel side positioning element 303 abuts against the side surface of the wheel 60, so that the wheel 60 is positioned from two directions, the wheel 60 can be reliably and accurately positioned, and the problem of inaccurate calibration of the center line of the vehicle caused by inaccurate positioning of the wheel 60 is solved.
