[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0015] A fixture for synchronously positioning the center hole and the lug of a steering knuckle includes a worktable 1 with four supporting feet at the bottom and a steering knuckle placed on the worktable 1. The steering knuckle includes a hollow cylindrical steering knuckle body 2 and a first straight rod 4, a second straight rod 11, and a third straight rod 13 disposed on the outer wall of the steering knuckle body 2. The third straight rod 14 is perpendicular to the first straight rod 4 and the second straight rod 11. The worktable 1 is provided with a center positioning protrusion 3 that mates with the center hole of the steering knuckle body 2. The worktable 1 is also provided with a lug positioning assembly that mates with the third straight rod 13. The outer wall of the steering knuckle body 2 is also provided with a first inclined rod 5 and a second inclined rod 6. The worktable 1 is provided with a first inclined positioning component 7 and a second inclined positioning component 8. The first inclined positioning component 7 is disposed between the first inclined rod 5 and the second straight rod 11, and the second inclined positioning component 8 is disposed between the second inclined rod 6 and the first straight rod 4.

[0016] In existing steering knuckle inspections, only the hole positions are typically inspected, without checking the relative positions of the first oblique rod 5 and the second oblique rod 6. This application, by setting the first oblique positioning component 7 and the second oblique positioning component 8, checks the relative positions of the first oblique rod 5 and the second oblique rod 6, ensuring the correctness of their positions. Specifically, the third straight rod 14 is perpendicular to both the first straight rod 4 and the second straight rod 11, and their angles are relatively easy to determine. However, the relative angles of the first oblique rod 5 and the second oblique rod 6 are relatively difficult to determine, therefore, their angles need to be checked.

[0017] Specifically, the first inclined positioning component 7 is disposed between the first inclined rod 5 and the second straight rod 11, and is used to measure whether the angle between the first inclined rod 5 and the second straight rod 11 is correct. The second inclined positioning component 8 is disposed between the second inclined rod 6 and the first straight rod 4, and is used to measure whether the angle between the second inclined rod 6 and the first straight rod 4 is correct. The center positioning protrusion 3 cooperates with the center hole of the steering knuckle body 2 to position the center of the steering knuckle. The lug positioning component is provided to position the lug of the steering knuckle. Specifically, the lug of the steering knuckle is positioned by the cooperation of the third straight rod 13 with the lug positioning component.

[0018] In some embodiments, the ear positioning assembly includes two ear positioning protrusions 12 arranged side by side, the end of the third straight rod 13 is located between the two ear positioning protrusions 12, and the ear positioning protrusions 12 are provided with ear positioning holes aligned with the holes on the third straight rod 13.

[0019] Specifically, the two side-by-side ear positioning protrusions 12 are designed to provide the position for the third straight rod 13. When placing the steering knuckle, it is inserted between the two side-by-side ear positioning protrusions 12. The ear positioning protrusions 12 have holes that align with the holes on the third straight rod 13. By inserting shafts of the same size into both, it is determined whether the hole position on the third straight rod 13 is correct. If the shaft can pass through the two holes, it indicates that the hole position is correct.

[0020] In some embodiments, one end of the first inclined positioning member 7 is flush with the second straight rod 11, and the other end is provided with a first inclined surface 9, which is aligned with one side wall of the first inclined rod 5.

[0021] Specifically, in use, the first inclined positioning piece 7 is pushed between the first inclined rod 5 and the second straight rod 11, so that one end of the first inclined positioning piece 7 is flush with the second straight rod 11, and the first inclined surface 9 is aligned with one side wall of the first inclined rod 5. If they fit well, it proves that the relative angle of the first inclined rod 5 is correct.

[0022] In some embodiments, the first inclined positioning member 7 further includes a first inclined positioning protrusion 14, which has a left positioning hole aligned with the upper hole of the first inclined rod 5.

[0023] Specifically, after confirming that the position of the first inclined rod 5 is correct in the previous step, it is necessary to check the position of the hole on it. After the first inclined positioning piece 7 is pushed into place, if the hole of the first inclined rod 5 can be aligned with the left positioning hole, it means that the position of the hole of the first inclined rod 5 is correct. The detection method can also be by inserting a shaft. If the shaft can be easily inserted through both holes, it means that the hole position is correct. In addition, it can also be observed directly whether they are aligned.

[0024] In some embodiments, one end of the second inclined positioning member 8 is flush with the first straight rod 4, and the other end is provided with a second inclined surface 10, which is aligned with one side wall of the second inclined rod 6.

[0025] Specifically, in use, the second inclined positioning piece 8 is pushed between the second inclined rod 6 and the first straight rod 4, so that one end of the second inclined positioning piece 8 is flush with the first straight rod 4, and the second inclined surface 10 is aligned with one side wall of the second inclined rod 6. If they fit well, it proves that the relative angle of the first inclined rod 5 is correct.

[0026] In some embodiments, the second inclined positioning member 8 further includes a second inclined positioning protrusion 15, which has a right positioning hole aligned with the upper hole of the second inclined rod 6.

[0027] Specifically, after confirming that the position of the second inclined rod 6 is correct in the previous step, it is necessary to check the position of the hole on it. After the second inclined positioning piece 8 is pushed into place, if the hole of the second inclined rod 6 can be aligned with the right positioning hole, it means that the position of the hole of the second inclined rod 6 is correct. The detection method can also be by inserting a shaft. If the shaft can be easily inserted through both holes, it means that the hole position is correct. In addition, you can also directly observe whether they are aligned.

[0028] By setting the center positioning protrusion 3 and the ear positioning assembly, the center hole and the ear of the steering knuckle are positioned synchronously. By setting the first inclined positioning component 7 and the second inclined positioning component 8, the relative angle of the first inclined rod 5 and the second inclined rod 6 is detected.

[0029] The technical solution of this utility model has been described above with reference to specific embodiments. However, it should be noted that the above description is only for explaining the solution of this utility model and should not be construed as a specific limitation on the scope of protection of the utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
