Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle inspection devices, in particular to a wheel positioning device for motor vehicle inspection. Background Art

[0002] Motor vehicles are referred to as "motor vehicles". They are wheeled "vehicles" that are driven or towed by their own power devices and can travel on land. They generally refer to vehicles that travel on roads for passengers or (and) transporting goods or performing special operations, including cars, trailers, trolleybuses, agricultural transport vehicles, motorcycles, motor tricycles and transport tractors (including wheeled tractors with trailers) and wheeled special mechanical vehicles. The motor vehicle inspection line is an automatic assembly line that uses modern optomechanical and computer measurement and control technology to test the safety, environmental protection and other performance of road-going motor vehicles. During the motor vehicle inspection process, the wheels need to be aligned to avoid accidents caused by vehicle movement during the inspection. Inspecting motor vehicles can eliminate vehicle safety hazards in a timely manner and reduce the occurrence of traffic accidents. During the motor vehicle inspection process, wheel alignment devices are needed to fix the wheels of the motor vehicle.

[0003] After searching, a Chinese patent publication number CN219956916U discloses a wheel positioning device for on-site motor vehicle inspection. The patent includes a base plate, a position adjustment structure is fixedly connected to the upper surface of the base plate, and an angle adjustment structure is arranged above the base plate. The position adjustment structure includes two sliding slot frames, the inner wall of each sliding slot frame is rotatably connected to a threaded rod, and the interior of each sliding slot frame is slidably connected to two sliding blocks, and the inner wall of each group of sliding blocks is threadedly connected to the outer surface of the threaded rod. A controller and two rotating motors are respectively arranged above the base plate, and the output end of each rotating motor power is fixedly connected to the left end of the threaded rod. The angle adjustment structure includes a support plate, the upper surface of the support plate is fixedly connected to a rotating bearing, and a rotating motor is arranged below the support plate. It can control the forward and reverse rotation adjustment of the equipment by being provided with a controller, and can drive the threaded rod to rotate forward or reverse by utilizing the operation of the rotating motor. However, this device is different from the prior art in that when locating the wheel, it often adopts the method of clamping one side of the wheel for positioning, which will cause problems such as tilting and offset, and the wheel is not fixed in all directions. It is also necessary to manually locate the center of the wheel, which is easy to cause errors during inspection, affecting the inspection accuracy and effect, and the practicality needs to be improved.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, a wheel alignment device for motor vehicle inspection includes a fixed seat 101, a lifting platform 102 is installed in the fixed seat 101, a power component for driving the lifting platform 102 to rise or fall is arranged in the fixed seat 101, a fixed plate 103 is arranged on the lifting platform 102, a rotating mechanism is installed on the top of the lifting platform 102, a No. 1 adjusting mechanism is installed on the rotating mechanism, a No. 2 adjusting mechanism is arranged on the No. 1 adjusting mechanism, the No. 1 adjusting mechanism includes a No. 1 bidirectional screw rod 303, two relatively arranged sliding sleeves 305 are threadedly connected to the No. 1 bidirectional screw rod 303, a connecting seat 306 is connected to the sliding sleeve 305 by bolts, and the No. 2 adjusting mechanism includes a No. 2 bidirectional screw rod 402, the No. 2 bidirectional screw rod 402 is perpendicular to the No. 1 bidirectional screw rod 303 The arrangement is such that a center block 403 is welded at the middle position of the No. 2 two-way screw rod 402, and a rotating handle 404 for rotation adjustment is connected to one end of the No. 2 two-way screw rod 402 by bolts, and the center block 403 is in the same plane as the No. 1 two-way screw rod 303, and two relatively arranged sliding blocks 405 are threadedly connected to the No. 2 two-way screw rod 402, and a clamping mechanism is installed on the sliding block 405. Through this arrangement, the No. 1 two-way screw rod 303 is located on the perpendicular bisector of the No. 2 two-way screw rod 402, and the center position of the No. 1 two-way screw rod 303 is on the axis of the rotating shaft 204, so that when the wheel is positioned, the rotating shaft 204 is aligned with the axle, and several groups of clamping mechanisms can jointly clamp the wheel to achieve stable and rapid positioning without causing problems such as tilting and offset.

[0026] In this embodiment, the second adjustment mechanism includes a mounting frame 401, which is connected to the connecting seat 306 by bolts, a second bidirectional screw rod 402 is rotatably connected in the mounting frame 401, and a sliding block 405 is slidably connected in the mounting frame 401.

[0027] In this embodiment, the clamping mechanism includes a connecting shaft 501, which is rotatably connected to the front side of the sliding block 405. One end of the connecting shaft 501 is connected to a fixed block 502 by bolts. An adjusting block 504 is provided on one side of the fixed block 502. Inclined friction surfaces 506 are provided on the opposite surfaces of the fixed block 502 and the adjusting block 504. Several groups of fixed blocks 502 and adjusting blocks 504 are matched to clamp the wheels of the motor vehicle in all directions.

[0028] In this embodiment, one end of the fixed block 502 is rotatably connected to an adjusting screw rod 503, and the adjusting screw rod 503 is threadedly connected to the adjusting block 504.

The output shaft of the motor 201 is connected to the worm 202 meshing with the worm gear 203 through a coupling. During the wheel detection process, the worm 202 cooperates with the worm wheel 203 to lock to prevent the wheel from rotating.

During the adjustment, the adjusting screw rod 503 is rotated, and the adjusting screw rod 503 drives the adjusting block 504 to move, so that the friction surface 506 can fit the edge positions of both sides of the wheel. Then, the lifting platform 102 is lowered, and the rotating block 304 is rotated. The rotating block 304 drives the first bidirectional screw rod 303 to rotate, and the first bidirectional screw rod 303 drives the sliding sleeve 305 and the connecting seat 306 to move away, which can adapt to wheels of different diameters and make the mounting frame 401 in the same position. At the radial side position of the wheel, the rotating block 304 is then rotated in the opposite direction, and the rotating handle 404 is adjusted at the same time, so that several groups of fixed blocks 502 and adjusting blocks 504 can fit in the appropriate position of the wheel, and the rotating block 304 will drive the sliding sleeve 305 to approach inward, and the sliding sleeve 305 drives the connecting seat 306 and the mounting bracket 401 to approach inward, and the mounting bracket 401 drives several groups of clamping mechanisms through the sliding block 405 to hold the wheel together. When the wheel is clamped, due to the setting of the No. 1 two-way screw rod 303 and the No. 2 two-way screw rod 402, the center of the wheel will be aligned with the axis center of the rotating shaft 204, which is convenient for various inspections.
