Description

Technical Field

[0001] The utility model relates to the technical field of wheel detection, in particular to a positioning structure for vehicle wheel detection. Background Technique

[0002] An automobile has the following definition: a non-railborne vehicle driven by power and having 4 or more wheels, mainly used for: carrying passengers and / or goods; towing vehicles carrying passengers and / or goods. With the development of social economy, the ownership of automobiles by people has increased rapidly.

[0003] When overhauling or transporting automobile wheels, a positioning mechanism is needed to position the wheels. The existing positioning mechanism uses a stop block to position the automobile, but the wheelbases of different automobiles are inconsistent, resulting in poor wheel positioning effect.

[0004] Therefore, it is necessary to provide a new positioning structure for vehicle wheel detection to solve the above technical problems. Content of the Utility Model

[0005] One of the purposes of the utility model is realized by adopting the following technical scheme:

[0006] A positioning structure for vehicle wheel detection includes a bottom plate. U-shaped plates are fixedly connected to both the left and right sides of the top of the bottom plate, and rectangular slots are opened on the U-shaped plates. Positioning plates are slidably connected to the inner cavities of the two rectangular slots near the front and rear, and lifting plates are fixedly connected to the bottoms of the positioning plates. Hollow plates adapted to them are slidably sleeved on the outer sides of the four lifting plates, and moving blocks are fixedly connected to the sides of the hollow plates close to the center of the top of the bottom plate. Threaded holes with opposite threads are opened on two longitudinally adjacent moving blocks, and the same first threaded rod is screwed into the inner cavities of the two threaded holes. Through holes are opened on the front sides of the two U-shaped plates. The rear ends of the two first threaded rods are respectively rotatably connected to the inner walls of the adjacent U-shaped plates, and the front ends of the two first threaded rods respectively penetrate into the inner cavities of the adjacent through holes and are fixedly connected with first hand cranks. Hydraulic push rods are arranged on the other sides of the four hollow plates, and connecting plates are fixedly connected to the power ends of the hydraulic push rods. Cross plates are fixedly connected to the four connecting plates, and second threaded rods are rotatably connected to the cross plates. Threaded sleeves adapted to them are screwed on the outer walls of the four second threaded rods. Limiting slots are opened on the four connecting plates, and sliders adapted to them are slidably connected to the inner cavities of the limiting slots. The left and right sides of the four sliders are respectively fixedly connected to the adjacent threaded sleeves and positioning plates. Second hand cranks are fixedly connected to the tops of the four second threaded rods. A rolling mechanism is arranged at the bottom of the bottom plate.

[0007] Further, load-bearing plates are fixedly connected to both the left and right sides of the bottom of the bottom plate.

[0008] Further, the rolling mechanism includes two cylinders, and the two cylinders are respectively arranged on the left and right sides at the bottom of the bottom plate. The power ends of the two cylinders are fixedly connected with movable plates. Grooves are respectively formed at the bottom of the bottom plate near the left and right sides, and a rotating plate is rotatably connected to the inner cavity of the groove. One side of each of the two rotating plates is fixedly connected with an N-shaped plate, and two rollers distributed front and back are rotatably connected to the inner cavity of the N-shaped plate.

[0009] Further, fixing plates are respectively fixedly connected to the bottom of the bottom plate near the left and right sides, and the fixing plates are located between the load-bearing plate and the grooves.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By rotating the first hand crank, the first threaded rod can be driven to rotate, so that the two moving blocks on the same threaded rod can move relatively or away from each other, and the two positioning plates can be driven to move relatively or away from each other through the hollow plate and the lifting plate, so that the distance between the two longitudinally adjacent positioning plates can be effectively adjusted according to the wheelbase of the vehicle wheels. After the adjustment of the distance between the two longitudinally adjacent positioning plates is completed, the hydraulic push rod can be started to pull the connecting plate close to the bottom plate, so as to drive the positioning plate close to the wheel and effectively position the wheel;

[0013] 2. Through the settings of the hollow plate, the lifting plate, the slider, the limit slot, the threaded sleeve, the second threaded rod and the second hand crank, the second threaded rod can be driven to rotate by rotating the second hand crank. The rotation of the second threaded rod drives the threaded sleeve to move up and down, and drives the positioning plate to lift in the inner cavity of the rectangular slot through the slider, so that the height of the positioning plate can be adjusted according to the height of the wheel axis, and the stability of wheel positioning is further improved;

[0014] 3. Through the setting of the load-bearing plate, the stability of the positioning structure during wheel detection can be improved. When the positioning structure needs to be carried, the bottom plate can be lifted upward, and the rollers can freely droop under the action of gravity. Then, by starting the cylinder to push the movable plate close to the rotating plate, the rotating plate can be clamped and fixed in cooperation with the fixing plate, so as to ensure the vertical setting of the rollers and the bottom plate, and improve the convenience of the staff to carry the bottom plate.

And sliders 14 adapted to them are slidably connected in the inner cavities of the limiting slots 13. The left and right sides of the four sliders 14 are respectively fixedly connected to the adjacent threaded sleeves 17 and positioning plates 4. Second hand cranks 18 are fixedly connected to the tops of the four second threaded rods 16.
