Vehicle Centering Device for Headlight Test Lane

Automotive aligner BZ-3B/BZ-3H (for light detection station)

The car aligner is used to align the vehicle entering the inspection station, so that the longitudinal centerline of the vehicle coincides with the detection centerline of the light meter (and the detection equipment such as the corner meter). If the vehicle does not stop, the left and right deviations detected by the light detection are meaningless - the regulator standardizes the action of "stopping" and eliminates the retest and judgment disputes caused by the parking position from the source.

The BZ-3B/BZ-3H adopts a cylinder symmetrical expansion structure: the front expansion rod is in a retracted state, and the vehicle is centered along the centerline of the driving; the cylinder pushes the left and right expansion rods to synchronously translate outward, and the center of the vehicle is aligned with the center of the driving center after the wheels are fitted on both sides.Alignment accuracy 0.125°, single alignment time < 5 seconds, does not occupy the detection beat, it is suitable for automotive safety performance testing line, automotive factory testing (assembly) line, and used in conjunction with lighting instruments, corner meters and other equipment.

I. Purpose and Scope of Application

• Used to align the vehicle under inspection in front of the inspection station, so that the longitudinal center line of the vehicle is aligned with the inspector;
• Suitable for automotive safety performance testing lines, automotive factory testing lines/assembly lines and other occasions, and used in conjunction with corner meters, lighting instruments and other equipment;
• BZ-3B: Suitable for axle load mass not greater than3500 kgvarious types of automobiles;
• BZ-3H: Suitable for axle load mass not greater than3000 kgVarious types of cars.

III. Working Principle and Main Structure

The aligner consists of a front aligner and a rear aligner. The front and rear mainframe structures are the same, and they are all composed of a lower frame, an upper frame, a cylinder, a drum, an expansion rod, etc. The rollers are mounted on the upper frame to support the wheels; the expansion rods translate left and right.

• 1-Lower frame 2-Upper frame 3-Cylinder 4-Roller
• 5— Expansion lever 6— Middle cover 7— Guide shaft 8— Side cover

Working process: The expansion rod retracting → vehicle is centered on the regulator, and the front and rear wheels are located on the outer side of the expansion rod. The → cylinder pushes the expansion rod to move → symmetrically left and right to fit the wheels. The vehicle center is aligned with the driving center, and the → detection is completed. The expansion rod retracts the minimum position and then the vehicle drives away.

4. Product Features

• Symmetrical expansion, auto-alignment:The left and right expansion rods are synchronously driven by cylinders and bidirectionally fit the wheels, eliminating the need to manually move the vehicle repeatedly;
• FasterSingle straightening time < 5 seconds, without dragging the detection line beat;
• by：The alignment accuracy is 0.125°, which meets the alignment requirements of lighting, corners, side slips and other items;
• No Fetal Injury:The wheels are supported by rollers, the expansion frame translation is not blocked, and the straightening process does not produce lateral tyre rubbing;
• Wide model coverage:BZ-3B applies to wheelbase 2600 ~ 4300mm, BZ-3H applies to wheelbase 1800 ~ 3500mm, taking into account both passenger cars and light commercial vehicles;
• Anterior-Posterior Split Structure:Front and rear aligners are installed separately to accommodate vehicles with different wheelbases;
• Pneumatic drive:No hydraulic system, simple structure and small maintenance.

V. Installation and Use Points

场地：车间进出口需留足空间，进口应能保证车辆直线驶入，出口应确保车轮完全驶离设备后再转向；基础施工前请与厂家核对地基图。

气源：建议在车间外单独设气泵房并留通风孔，车间供气 1 MPa，配 0.8 m³（2.5 kW 或 4 kW）气泵。

安装：调整设备行车中心与检测线行车中心线重合；用水平尺（或水准仪）置于滚筒上检查，使机架上平面与地面平齐、滚筒上母线水平，调平后锁紧螺母并调整侧顶螺栓固定台架；调平螺栓处、围板底部及台架前后与基础的缝隙灌注混凝土，使主机底面与地基接触良好。

使用注意：

• 严禁人员在摆正器上穿行，测试中车辆前后严禁站人或通行；
• 不允许轴载质量大于设备最大承载质量的车辆检测或通过；
• 受检车辆轮胎气压应达到规定值，底盘及胎面粘附的泥砂、石块须清除干净；
• 车辆按行车中心线低速、平稳驶入驶出，严禁急刹车；驶入驶出时扩张杆须处于最小状态；
• 检测应在车辆空载状态下进行；雨天或洗车后须待水渍不再滴落到设备上再检测，地基坑内不得进水。

六、维护与保养

• 每天：检查各滚筒转动是否灵活，清洁滚筒表面污物；
• 每周：检查各气缸工作是否正常、扩张杆行程是否符合要求；
• 每月：检查各滚筒轴承，出现异响或转动不灵活应及时调整检修，必要时更换轴承；
• 每季度：检查各螺栓、螺钉是否紧固。

如需按车辆轴载／轴距选型，或需要灯光检测工位的整体配套方案，欢迎联系我们提供选型建议与地基图核对。
