The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] See also Figures 1 to 5The utility model provides a technical solution: a vehicle wheel hub dynamic balance detection tool, including a wheel balancing machine body 1, including:

[0032] The side wall of the wheel balancing machine body 1 is provided with a lifting assembly 2, which is used to move the wheel hub up and down. The lifting assembly 2 includes a screw rod 203, which is rotatably connected to the inside of the wheel balancing machine body 1. The outer peripheral wall of the screw rod 203 is threadedly connected to a lifting plate 201, and a convex part 202 is fixedly installed on the side wall of the lifting plate 201. A groove 101 is provided on the side wall of the wheel balancing machine body 1, and the convex part 202 is slidably connected to the inside of the groove 101. The side wall of the wheel balancing machine body 1 is fixedly connected to a limiting part 204, and the lifting plate 201 is slidably connected to the side wall of the limiting part 204. The limiting part 204 is used to increase the stability of the movement of the lifting plate 201, thereby avoiding shaking and tilting of the lifting plate 201 when moving up and down.

[0033] A driving motor is fixedly installed inside the groove 101, and the output shaft of the driving motor is fixedly connected to the screw rod 203. The convex part 202 is threadedly connected to the screw rod 203. The motor can drive the screw rod 203 to rotate. At this time, the screw rod 203 can drive the convex part 202 and the lifting plate 201 to move up and down, making it convenient to place the tire on the lifting plate 201 for convenient disassembly and assembly.

[0034] The bottom of the lifting assembly 2 is provided with a support assembly 3 for supporting it, and the support assembly 3 includes a support member 301, which is rotatably connected to the bottom of the lifting plate 201, and a rotating plate 205 is movably hinged on the side of the lifting plate 201 away from the convex member 202. The support member 301 is against the bottom of the rotating plate 205, and the bottoms of the lifting plate 201 and the rotating plate 205 are both provided with a sliding groove 303, and are connected to each other. The interior of the sliding groove 303 is slidably connected to the support plate 302, and the rotating plate 205 is rotated upward until the rotating plate 205 and the lifting plate 201 are in the same horizontal plane, and then rotated ninety degrees. The two sets of support members 301 are moved so that the support members 301 are against the bottom of the rotating plate 205. At this time, the support members 301 can support the rotating plate 205. Secondly, by sliding the support plate 302 at the bottom of the rotating plate 205 into the slide groove 303 at the bottom of the lifting plate 201, the rotating plate 205 can be further supported and fixed, thereby improving the stability of the rotating plate 205 when the tire is placed. When the wheel balancer body 1 is not needed, the rotating plate 205 can be rotated and folded downward by reversing the operation of the above parts, thereby saving space when the wheel balancer body 1 is placed or transferred.

[0035] The top of the lifting assembly 2 is provided with a limiting assembly 4, which is used to clamp and limit the wheel hub. The limiting assembly 4 includes a slide plate 401, which is slidably connected to the top of the lifting assembly 2. The top of the slide plate 401 is slidably connected to a clamping member 402, and the clamping members 402 are symmetrically distributed. The internal rotation of the slide plate 401 is connected to a bidirectional screw 404, and one end of the bidirectional screw 404 passes through the outer wall of the slide plate 401, and the connecting member 403 is threadedly connected to the outer peripheral wall of the bidirectional screw 404; the top of the slide plate 401 is provided with a transverse groove 401, and the bottom of the clamping member 402 is fixedly installed with a connecting member 403, and the connecting member 403 is slidably connected to the inside of the transverse groove 401. By manually rotating the bidirectional screw 404, the two groups of connecting members 403 and the clamping member 402 can be driven to move toward each other until the two groups of clamping members 402 clamp and fix the tire, which can increase the stability of the tire when moving, avoids the need to manually support the tire, and saves manpower.

[0036] An elastic clip 5 for fixing the skateboard 401 is provided on the top of the rotating plate 205, and the elastic clip 5 is clamped on the side wall of the skateboard 401. A return spring 6 is fixedly connected between the elastic clip 5 and the rotating plate 205. By pressing the elastic clip 5 downward to shrink it inside the rotating plate 205, the tire on the skateboard 401 can be pushed to the shaft of the wheel balancing machine body 1 for installation and inspection.

[0037] When the utility model is in use, the rotating plate 205 is first rotated upward until the rotating plate 205 and the lifting plate 201 are at the same horizontal plane, and then the two sets of support members 301 are rotated 90 degrees so that the support members 301 and the bottom of the rotating plate 205 are abutted, and the support plate 302 at the bottom of the rotating plate 205 is slid into the sliding groove 303 at the bottom of the lifting plate 201;

[0038] Secondly, place the tire between the two sets of clamping parts 402, and manually rotate the bidirectional screw 404 to drive the two sets of connecting parts 403 and the clamping parts 402 to move toward each other until the two sets of clamping parts 402 clamp the tire. At this time, the motor can drive the screw rod 203 to rotate, and the screw rod 203 can drive the lifting plate 201 and the tire to move upward until the center position of the tire corresponds to the shaft of the wheel balancer body 1;

[0039] Finally, the elastic clamp 5 is pressed downward to shrink it inside the rotating plate 205. At this time, the tire can be pushed to the shaft of the wheel balancing machine body 1 for installation and testing.
