[0026] Embodiment:

[0027] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , an automobile impeller runout detection device, including a base 1, a symmetrically distributed sliding seat 2 is slidably connected to the top wall of the base 1, and the sliding seat 2 slides in the base 1, so as to conveniently adjust the position to fix impellers of different lengths. A conical cylinder 3 is rotatably connected to the inner wall of the sliding seat 2, and further includes:

[0028] A driving extrusion positioning assembly, the driving extrusion positioning assembly includes a driving rod 14 rotatably connected to the inner wall of the conical cylinder 3, a driven rod 7 is slidably connected to the inner wall of the driving rod 14, a knob 13 is fixedly connected to one end of the driving rod 14 away from the driven rod 7, a screw rod 8 is fixedly connected to one end of the driven rod 7 away from the driving rod 14, a attaching plate 9 is rotatably connected to one end of the screw rod 8 away from the driving rod 14, a uniformly distributed first folding rod 10 is rotatably connected to the outer wall of the attaching plate 9, an extrusion plate 12 is fixedly connected to one end of the first folding rod 10 away from the attaching plate 9, a second folding rod 11 is rotatably connected to the inner wall of the extrusion plate 12, and one end of the second folding rod 11 away from the extrusion plate 12 is rotatably connected to the conical cylinder 3. Holding the knob 13 drives the driving rod 14 to rotate, thereby driving the driven rod 7 and the screw rod 8 to rotate. The screw rod 8 is in threaded cooperation with the conical cylinder 3, thereby pushing the attaching plate 9 to move. The attaching plate 9 drives the first folding rod 10 and the second folding rod 11 to adapt and fold and rotate through the extrusion plate 12, so as to squeeze the impeller diameter, thereby adapting to impellers of different diameter sizes for extrusion and fixation;

[0029] A driven gear 4, fixedly connected to the outer wall of the conical cylinder 3;

[0030] A bottom limit tooth 16, fixedly connected to the outer wall of the base 1, and the bottom limit teeth 16 are uniformly distributed;

[0031] A limiting assembly, arranged on the inner wall of the sliding seat 2.

[0032] Referring to Figure 4 and Figure 5, the limiting component includes a top plate 22 slidably connected to the inner wall of the sliding seat 2, and two groups of top plates 22 are symmetrically distributed. A strong tension spring 21 is fixedly connected between the two groups of top plates 22. One end of the top plate 22 away from the strong tension spring 21 is slidably connected to a bottom plate 17. A limiting handle 19 is rotatably connected to the inner wall of the bottom plate 17. Symmetrically distributed extrusion blocks 20 are fixedly connected to the outer wall of the limiting handle 19, and the extrusion blocks 20 are in contact with the outer wall of the bottom plate 17. A limiting frame 18 is fixedly connected to the top wall of the extrusion block 20, and the outer wall of the limiting frame 18 is in contact with the outer wall of the bottom limiting teeth 16. By pushing the sliding seat 2, its top plate 22 slides adaptively through the strong tension spring 21 and returns to position, thus getting stuck in the side limiting teeth 15. Then, according to needs, hold the limiting handle 19 and rotate it, thereby driving the limiting frame 18 to rotate. When the limiting frame 18 is completely squeezed and stuck in the bottom limiting teeth 16, at this time, the extrusion block 20 squeezes the bottom plate 17. Since the extrusion block 20 is of an elliptical structure, the greater the rotation angle, the greater the extrusion force and the firmer the fixation.

[0033] Refer to Figure 1 and Figure 4 , symmetrically and evenly distributed side limiting teeth 15 are fixedly connected to the outer wall of the base 1, and the outer wall of the side limiting teeth 15 is in contact with the outer wall of the top plate 22. The side limiting teeth 15 and the bottom limiting teeth 16 have opposite tooth directions, so that the limiting handle 19 and the limiting frame 18 integrally connected by the top plate 22 and the bottom plate 17 exert extrusion forces in opposite directions to strengthen the fixation.

[0034] Refer to Figure 1 , a driving gear 5 is rotatably connected to the outer wall of the right sliding seat 2, and the outer wall of the driving gear 5 is meshed with the outer wall of the driven gear 4. A rotating handle 6 is rotatably connected to the outer wall of the driving gear 5. By rotating the rotating handle 6 to drive the driving gear 5 to rotate, and then meshing and driving the driven gear 4 to rotate, it is convenient to drive the impeller to rotate, thus facilitating the rotation and jump detection.

[0035] Refer to Figure 1 , a detector 23 is detachably connected to the outer wall of the base 1, and the jump detection is carried out through the detector 23.

[0036] Specifically, when this automotive impeller runout detection device is in operation / use: First, hold the knob 13 by hand and drive the drive rod 14 to rotate, thereby driving the driven rod 7 and the screw rod 8 to rotate. The screw rod 8 is in threaded cooperation with the conical cylinder 3, and then the pressing plate 9 is pushed to move. The first folding rod 10 and the second folding rod 11 are driven by the pressing plate 9 to adapt and are folded and rotated by the pressing plate 12, so as to squeeze the impeller diameter, thereby adapting to impellers of different diameters for squeezing and fixing. At the same time, by pushing the sliding seat 2, the top plate 22 slides adaptively along the sliding plate through the strong tension spring 21 and returns, so as to be stuck in the side limit teeth 15. Then, according to needs, hold the limit handle 19 by hand and rotate it, thereby driving the limit frame 18 to rotate. When the limit frame 18 is completely squeezed and stuck in the bottom limit teeth 16, at this time, the pressing block 20 presses the bottom plate 17. Since the pressing block 20 is of an elliptical structure, the greater the rotation angle, the greater the pressing force and the firmer the fixation. The side limit teeth 15 and the bottom limit teeth 16 are of opposite tooth direction structures, so that the top plate 22 and the bottom plate 17 are connected integrally with the limit handle 19 and the limit frame 18 to exert opposite-direction pressing forces, strengthening the fixation. Its disassembly and installation only require rotating the limit handle 19.

[0037] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
