[0028] Example 1: Please refer to Figures 1 to 8 :

[0029] The utility model proposes a device for quickly clamping and accurately positioning a car wheel hub, comprising: a positioning platform mounting frame 1, a directional guide cylinder 101 fixedly connected to the top of the positioning platform mounting frame 1, a wheel hub placing platform 3 movably connected in the directional guide cylinder 101, the upper surface of the positioning platform mounting frame 1 is connected to the inner sleeve 2 by welding, a push rod guide plate 4 is installed above the wheel hub placing platform 3 by bolts, the center of the wheel hub placing platform 3 is rotatably connected to the positioning rotary cylinder 5 by a bearing, the upper end of the positioning rotary cylinder 5 is rotatably connected to the push rod guide plate 4, the positioning rotary cylinder 5 is movably connected to the inside of the inner sleeve 2, four push rod slots 401 are provided on the push rod guide plate 4, the upper surface of the positioning rotary cylinder 5 is hinged with four slider push rods 502, the outer end of the slider push rod 502 is hinged with the wheel hub push rod 6, and the wheel hub push rod 6 is slidably connected in the push rod slot 401; the car wheel hub is placed by the wheel hub placing platform 3, and a boss structure is provided at the center above the wheel hub placing platform 3, which is conducive to the accurate placement of the wheel hub and reduces the placement deviation of the wheel hub.

[0030] In the embodiment of the present disclosure, four vertical guide grooves 102 are provided on the inner wall of the directional guide cylinder 101, and four return springs 103 are fixedly connected to the upper surface of the positioning platform mounting frame 1, and the upper ends of the return springs 103 are fixedly connected to the lower surface of the wheel hub placement platform 3; under normal circumstances, the wheel hub placement platform 3 is pushed upward by the pushing action of the return springs 103, so that the upper surface of the wheel hub placement platform 3 protrudes from the upper surface of the directional guide cylinder 101, and when the automobile wheel hub is placed on the wheel hub placement platform 3, the return springs 103 are squeezed under the action of the gravity of the automobile wheel hub, and the automobile wheel hub and the wheel hub placement platform 3 sink downward at the same time.

[0031] In the embodiment of the present disclosure, a sleeve slide groove 201 is provided at the upper center of the inner sleeve 2, and two oblique adjustment grooves 202 are provided at the inner edge of the sleeve slide groove 201. The outer surface of the positioning rotor 5 is fixedly connected with two oblique convex grooves 501 of a curved structure; with the cooperation of the inner sleeve 2 and the positioning rotor 5, when the hub placement platform 3, the push rod guide plate 4 and the positioning rotor 5 automatically sink under the action of gravity, the oblique convex grooves 501 form a sliding connection with the oblique adjustment groove 202, so that the positioning rotor 5 rotates while automatically moving downward; the outer surface of the hub placement platform 3 is provided with four lifting ridges 301, and the lifting ridges 301 are slidably connected to the vertical guide grooves 102, which play a guiding role to prevent the hub placement platform 3 from rotating during the up and down sliding process inside the directional guide cylinder 101.

[0032] In the embodiment of the present disclosure, the outer end of the wheel hub push rod 6 is fixedly connected to a push rod anti-sliding block 601 made of rubber material, and the upper surface of the wheel hub push rod 6 is fixedly connected to a push rod push shaft 602, and the push rod push shaft 602 is hinged to the outer end of the slider push rod 502; when the positioning rotary cylinder 5 rotates, the wheel hub push rod 6 is pushed through the connection between the slider push rod 502 and the push rod push shaft 602, and the wheel hub push rod 6 is pushed to slide outward along the push rod slide groove 401, so that the push rod anti-sliding block 601 is tightly fitted with the inner wall of the automobile wheel hub, thereby realizing the positioning of the automobile wheel hub.

[0033] Example 2: Based on Example 1, the side of the wheel hub push rod 6 is provided with a convex strip, and the inner wall of the push rod slide groove 401 is provided with a long strip groove body. The side convex strip of the wheel hub push rod 6 is slidably connected to the inside of the inner wall groove body of the push rod slide groove 401, playing a guiding role, so that the wheel hub push rod 6 moves in a straight line in the push rod guide plate 4. At the same time, through the synchronous action of the wheel hub push rods 6 at four places, the automobile wheel hub is moved to the center of the upper surface of the wheel hub placement table 3, and the automobile wheel hub is automatically corrected.

[0034] The working principle of this embodiment is as follows: Under normal circumstances, the wheel hub placement platform 3 protrudes from the directional guide cylinder 101 under the push of the return spring 103, and the wheel hub push rod 6 shrinks inside the push rod slide groove 401. When the automobile wheel hub is placed on the wheel hub placement platform 3 by a robot or manual handling, the wheel hub is subjected to downward pressure under the weight of the automobile wheel hub itself. The downward pressure gravity is greater than the elasticity of the return spring 103, so that the wheel hub placement platform 3, the push rod guide plate 4, and the positioning rotary cylinder 5 move downward synchronously. At the same time, the positioning rotary cylinder 5 slides downward in the sleeve slide groove 201, and the oblique convex pattern 501 of the curved structure forms a sliding connection with the oblique adjustment groove 202, prompting the positioning rotary cylinder 5 to automatically rotate during the downward movement. As the positioning rotary cylinder 5 rotates, the wheel hub push rod 6 is pushed, pushing the wheel hub push rod 6 along The push rod slot 401 slides outward, so that the push rod anti-slide block 601 fits tightly against the inner wall of the automobile wheel hub, thereby realizing the positioning of the automobile wheel hub. At the same time, through the synchronous action of the four wheel hub push rods 6, the automobile wheel hub is moved to the center of the upper surface of the wheel hub placement platform 3 to correct the automobile wheel hub. When removing the wheel hub, the wheel hub is taken up vertically by a manipulator or a tool, so that the gravity exerted on the reset top spring 103 is less than its own elasticity, and under the elastic action of the reset top spring 103, the wheel hub placement platform 3 is pushed up again to reset it. At the same time, the positioning rotary cylinder 5 slides upward inside the sleeve slot 201, driving the positioning rotary cylinder 5 to rotate itself, and pulling the wheel hub push rod 6 inward through the slider push rod 502, so that the push rod anti-slide block 601 is separated from the inner wall of the wheel hub, automatically releasing the positioning of the wheel hub.
