DETAILED DESCRIPTION

[0015] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0016] like Figure 1-4 As shown, the utility model provides a tire dynamic uniformity detection device, including a dynamic balancing machine 1, a detection shaft 2 is provided on one side of the dynamic balancing machine 1, and a tire fixing plate 3 is fixedly connected to the detection shaft 2, which is used to fix the tire on the detection shaft 2. A screw 4 and a guide rod 5 are also arranged side by side on the same side of the dynamic balancing machine 1 as the detection shaft 2, and a movable seat 6 is slidably matched on the screw 4 and the guide rod 5, and the movable seat 6 is L-shaped. A telescopic shaft 10 is rotatably matched on the vertical surface of the movable seat 6, and a circular tire tray 9 is fixedly connected to the end of the telescopic shaft 10, and the tire tray 9 is arranged coaxially with the detection shaft 2. Four slide rails 18 are provided on the tire tray 9, and each slide rail 18 is slidably matched with a centering slider 12, and each centering slider 12 is fixedly connected to a centering plate 14, and the centering plate 14 is arc-shaped, and the four centering plates 14 are arranged in a circular shape. A turntable 11 is rotatably mounted on the telescopic shaft 10 between the tire tray 9 and the vertical surface of the movable seat 6. Four pins are fixedly connected to the turntable 11 and the centering slider 12. A linkage plate 13 is rotatably mounted between adjacent pins of the turntable 11 and the centering slider 12.

[0017] A placement groove 7 is provided on the horizontal surface of the movable seat 6, and a guide inclined plate 17 is provided on one side of the placement groove 7.
