Description

Technical Field

[0001] This utility model relates to the field of four-wheel alignment technology, specifically a four-wheel alignment fixture. Background Technology

[0002] The working principle of a four-wheel alignment fixture: The fixture uses sensors to measure the position and angle of the wheels. The sensors transmit the measurement data to the lower-level computer of the four-wheel alignment system for processing and calculation, ultimately determining the wheel alignment parameters. By adjusting the mechanism, the position and angle of the fixture can be fine-tuned to ensure measurement accuracy.

[0003] Currently, all four positioning heads on the four-wheel alignment fixture are fixed to the fixture. Not only are the positioning heads on the fixture difficult to disassemble and replace, but the positioning distance between the two positioning heads on the fixture positioning frame is also fixed. For different models of vehicles with different wheel diameters, this results in a large difference between the positioning fixture and the wheel diameter, making the fixture positioning operation inconvenient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, a four-wheel alignment fixture includes two positioning end plates 1 connected by connecting rods 2. Two connecting rods 2 are connected at their midpoints, with a connecting plate 3 on each connecting plate 3. A level plate 31 is mounted on the connecting plate 3. A double-ended screw 4 connects the two positioning end plates 1, with one end of the screw 4 connected to a knob 7. The screw 4 passes through a through hole into the level plate 31. Positioning frames 6 are mounted at both ends of the screw 4 via screw sleeves 5. Mounting plates 8 are mounted at the bottom of each positioning frame 6 via an adjustment mechanism. A positioning plate 9 is mounted at the bottom of the mounting plate 8 via a connecting mechanism. A positioning head 10 is mounted at the bottom of the positioning plate 9. The positioning head 10 of the four-wheel alignment fixture is easily disassembled, replaced, and adjusted.

[0021] Specifically, the adjustment mechanism includes a limiting groove 11, a bidirectional screw 12, a threaded block 13, and a second knob 14. The bottom of both positioning frames 6 is provided with a limiting groove 11. The limiting groove 11 is provided with a bidirectional screw 12 and a threaded block 13. The threaded block 13 is connected to the bidirectional screw 12. One end of the bidirectional screw 12 is connected to the second knob 14. The bottom of the threaded block 13 is connected to the mounting plate 8. When the second knob 14 is rotated, it drives the bidirectional screw 12 to rotate. The two threaded blocks 13 on the bidirectional screw 12 slide within the limiting groove 11, which drives the two mounting plates 8 to move closer or further apart at the bottom of the positioning frame 6, thereby adjusting the distance between the two positioning heads 10 on the positioning frame 6, which is convenient for positioning wheels of different diameters.

[0022] Furthermore, the connecting mechanism includes a fixing bolt 15 and a nut 16. The bottom of the mounting plate 8 is provided with a fixing bolt 15, and the end of the positioning plate 9 away from the positioning head 10 is provided with a mounting hole. The positioning plate 9 is fixedly installed to the mounting plate 8 by the nut 16 on the fixing bolt 15. The positioning plate 9 is installed on the fixing bolt 15, and the nut 16 is installed on the fixing bolt 15 and tightened to fix the positioning plate 9 with the positioning head 10 on the mounting plate 8.

[0023] Furthermore, each of the two positioning frames 6 has a guide hole at both ends. The two ends of the two positioning frames 6 are slidably mounted on the connecting rod 2 through the guide hole. When the two positioning frames 6 move, the two ends of the positioning frames 6 slide on the connecting rod 2, which has the function of limiting and guiding.

[0024] Furthermore, limiting blocks are provided on both sides of the limiting slide groove 11, and limiting grooves are provided on both sides of the threaded block 13. The limiting blocks are located inside the limiting grooves. When the threaded block 13 moves on the bidirectional screw 12, the threaded block 13 moves within the limiting slide groove 11 through the limiting blocks and limiting grooves, thereby increasing the stability of the adjustable structure of the mounting plate 8 and the positioning head 10.

[0025] Furthermore, a locking bolt is provided on the positioning end plate 1 on one side of the first knob 7 through a locking screw hole. The locking bolt is correspondingly set with the double-ended screw 4. Tightening the locking bolt can lock the double-ended screw 4 on the positioning end plate 1.

[0026] Furthermore, the two positioning end plates 1 and the two connecting rods 2 are integrally formed, and the positioning end plates 1, connecting rods 2 and positioning frame 6 are all made of high-strength stainless steel, resulting in a high-strength fixture structure.

[0027] The usage method of this embodiment is as follows: The positioning plate 9 is installed on the fixing bolt 15, and the nut 16 is installed on the fixing bolt 15 and tightened. The positioning plate 9 with the positioning head 10 is fixed on the mounting plate 8. The second knob 14 is rotated to drive the bidirectional screw 12 in the bottom limiting slide groove 11 of the positioning frame 6 to rotate. The two threaded blocks 13 on the bidirectional screw 12 slide within the limiting slide groove 11, causing the two mounting plates 8 to move closer or further apart at the bottom of the positioning frame 6. The distance between the two positioning heads 10 at the bottom of the positioning frame 6 is adjusted. The first knob 7 is rotated to drive the positioning plate 9 to rotate. The double-headed screw 4 between the two positioning end plates 1 rotates, and the two screw sleeves 5 on the double-headed screw 4 drive the two positioning frames 6 to move closer or further apart. When the two positioning frames 6 move, the two ends of the positioning frames 6 slide on the two connecting rods 2. The positioning heads 10 at the bottom ends of the two positioning frames 6 are used to position the four wheels. The positioning heads 10 are connected by nuts 16 and fixing bolts 15. The positioning heads 10 of the four-wheel positioning fixture are easy to disassemble, replace and adjust, and the distance between the two positioning heads 10 on the positioning frame 6 can be adjusted, which is convenient for positioning four wheels with different wheel diameters.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
