Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1, the utility model discloses a flexible top cap centering table, include: the four-surface mechanism comprises a centering table trolley 1, a tetrahedral mechanism 2 and a turning clamp 3, wherein the tetrahedral mechanism 1 is arranged on the centering table trolley 2, and the turning clamp 3 is arranged on the tetrahedral mechanism 2;

the centering platform trolley 1 comprises castors 101, a trolley bottom plate 102, handrails 103 and limiting wheels 104, wherein the handrails 103 are arranged on one side of the trolley bottom plate 102, and the castors 101 and the limiting wheels 104 are arranged at the bottom of the trolley bottom plate 102; the truckle 101 adopts 6 universal wheels, makes things convenient for the dolly to turn to, increases the support of dolly simultaneously, can place the bottom plate and warp. The standard hole sites are arranged on the trolley bottom plate 102, so that the tetrahedral clamp and the turning clamp can be conveniently installed. The limiting wheel 104 is used in cooperation with a ground positioning mechanism for positioning the centering table trolley.

Tetrahedron mechanism 2 is including propping up base 201, carousel 202, pivot 203, base 204, anchor clamps 205, tetrahedron 206, motorcycle type detection mechanism 207 and bolt mechanism 208, pivot 203 sets up prop up on the base 201, the one end of pivot 203 sets up carousel 202, set up bolt mechanism 208 on the carousel 202, the other end of pivot 203 sets up motorcycle type detection mechanism 207, tetrahedron 206 sets up between the both ends of pivot 203, anchor clamps set up on tetrahedron 206. The manual rotating turntable 202 drives the rotating shaft 203, the base 204 and the clamp 205 to rotate to the corresponding vehicle model position. The vehicle type detection mechanism 207 identifies a corresponding vehicle type from the position of the tetrahedral rotation.
