Technical Field

[0001] The utility model relates to the technical field of wheel alignment, and more specifically to a four-wheel alignment device for automobile detection. Background Art

[0002] Automobile inspection is an examination to determine the technical condition or working ability of the automobile. During the use of the automobile, as the use time increases (or the mileage increases), its parts gradually wear, corrode, deform, age, and the lubricant deteriorates, causing the clearance of the mating pairs to become larger, causing loose movement, vibration, noise, and air, water, and oil leakage, resulting in a decline in the technical performance of the automobile. When the automobile is undergoing a four-wheel balance test, a four-wheel alignment and balancing device is required for inspection.

[0003] When the existing four-wheel alignment device is working, it is usually necessary to park the vehicle on top of the four-wheel alignment frame and limit the wheels by rollers to ensure the purpose of accurate wheel adjustment. However, the four-wheel alignment process only relies on the roller team to limit the wheels, which cannot accurately prevent the vehicle wheels from shaking or moving during the inspection, thereby directly affecting the reliability of the positioning process and the final result.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a four-wheel alignment device for automobile inspection, comprising a lifting base 1, four corners of the top of the lifting base 1 are movably installed with limited roller groups 2, the tops of both sides of the lifting base 1 are fixedly installed with assembly plates 3, one side of the assembly plate 3 is movably installed with a gear box 4, a bidirectional screw rod 5 is movably installed inside the gear box 4, a driven gear 6 is fixedly installed in the middle part of the bidirectional screw rod 5, moving blocks 7 are movably installed on both sides of the surface of the bidirectional screw rod 5, a positioning rod 8 is fixedly installed on one side of the moving block 7, a plurality of bearings 9 are arranged on the surface of the positioning rod 8, and a rotating drum 10 is movably installed on the surface of the bearing 9.

[0023] Among them, the function of improving the accuracy of vehicle four-wheel alignment measurement is achieved through the cooperation of the limiting roller group 2, the gear box 4, the bidirectional screw 5, the moving block 7, the positioning rod 8, the bearing 9, and the rotating drum 10. The wheel can be actively clamped to accurately fix the vehicle on the top of the lifting base 1 to ensure that the wheel will not shake during the measurement process, thereby enabling the four-wheel alignment device to ensure the accuracy of the measurement results, provide reliable data support for subsequent adjustments, and realize bidirectional active clamping, which is suitable for wheels of different diameters and increases the flexibility of the device.

[0024] A support base 11 is fixedly mounted on one side of the top of the gear box 4 , a small motor 12 is fixedly mounted on the top of the support base 11 , and a driving gear 13 is fixedly connected to one side of the small motor 12 via a rotating shaft.

[0025] The driving function is realized by the cooperation between the small motor 12 and the driving gear 13, so that the wheels can be automatically clamped after the vehicle stops, thereby avoiding maintenance personnel from fixing the vehicle through additional steps, thereby increasing work efficiency.

[0026] An inspection plate 14 is threadedly connected to one side of the gear box 4 , and limit plates 15 are fixedly installed on both sides of the bidirectional screw rod 5 .

[0027] The limiting plate 15 is used to limit the moving block 7, so as to prevent the moving block 7 from excessively moving outwards and causing damage to the positioning rod 8, thereby increasing the safety of the device.

[0028] A cavity 16 is opened through one end of the positioning rod 8, a pressure switch 17 is fixedly installed in the middle part of the inner wall of the cavity 16, a transmission rod 18 is movably installed on one side of the cavity 16, and a stop pad 19 is fixedly installed at one end of the transmission rod 18.

[0029] Among them, the function of accurately controlling the supporting position is realized by the pressure switch 17 and the transmission rod 18, thereby preventing the drum 10 from going too deep and causing damage to the vehicle. The function of protecting the vehicle contact surface is realized by the pad 19, thereby preventing the end of the drum 10 from directly contacting the inner wall of the vehicle wheel cover, reducing scratches and wear on the inner wall of the vehicle wheel cover, thereby protecting the vehicle's external coating and the inner wall of the vehicle wheel cover.

[0030] A baffle 20 is fixedly mounted on the surface of the transmission rod 18 , and a spring 21 is sleeved on the surface of the transmission rod 18 .

[0031] The baffle plate 20 and the spring 21 provide a buffering function, thereby preventing the pad 19 from impacting the inner wall of the wheel cover when it penetrates deeply, and further reducing scratches and wear on the inner wall of the vehicle wheel cover.

[0032] Polished rods 22 are fixedly mounted at two corners of the bottom of the front side of the assembly plate 3 , and connecting ears 23 are fixedly mounted at both sides of the bottom of the gear box 4 . The connecting ears 23 are sleeved on the surface of the polished rod 22 .

[0033] The function of ensuring the linear movement of the gear box 4 is achieved by the light rod 22 and the connecting ear 23, thereby enabling the drum 10 to be separated from the interior of the lifting base 1 when the vehicle enters, while ensuring that the gear box 4 maintains a stable horizontal position during operation.

[0034] An L-plate 24 is fixed through one end of the light rod 22 , and an electric telescopic rod 25 is fixedly installed on one side of the L-plate 24 . The output end of the electric telescopic rod 25 is fixedly connected to the inspection plate 14 .

[0035] The function of controlling the working position of the drum 10 is realized by the electric telescopic rod 25, thereby ensuring the required working length of the drum 10 when facing different wheel widths.

[0036] The working principle and use process of the utility model are as follows: when the vehicle travels to the limit roller group 2, the vehicle is lifted up by the lifting base 1, and the small motor 12 drives the driving gear 13 to rotate through the rotating shaft, and drives the driven gear 6 to rotate through the driving gear 13, and drives the bidirectional screw rod 5 to rotate through the driven gear 6, and the bidirectional screw rod 5 adjusts the spacing between the rotating drums 10 on both sides through the moving block 7. When the spacing between the rotating drums 10 is slightly larger than the wheel diameter, the electric telescopic rod 25 pushes the gear box 4 to move toward the vehicle through the inspection plate 14. During this period, the gear box 4 is ensured to move linearly through the connecting ear 23 and the light rod 22, and the rotating drum 10 is driven to move by the gear box 4. When the rotating drum 10 contacts the inner wall of the vehicle wheel cover through the abutment 19, the abutment 19 drives the baffle 20 to compress the spring 21 through the transmission rod 18. At the same time, the transmission rod 18 touches the pressure switch 17. At this time, the electric telescopic rod 25 stops working, and the spacing between the rotating drums 10 is reduced again through the small motor 12, and the wheel is clamped by the rotating drum 10.
