Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and 2, the automotive frame turnover mechanism comprises a turnover rack 3, wherein a frame baffle 8 and a beam pushing mechanism 9 matched with the frame baffle 8 are arranged on the turnover rack 3, the frame baffle 8 is fixedly connected with the turnover rack 3, a notch is arranged below the frame baffle 8, and an extending end of the beam pushing mechanism 9 can pass through the notch; a movable middle plate 10 capable of moving up and down is arranged below the turnover table frame 3, a main lifting mechanism 1 is arranged below the movable middle plate 10, a turnover plate 6 and a telescopic mechanism 5 are hinged on the movable middle plate 10, the bottom of the telescopic mechanism 5 is hinged with the movable middle plate 10, and the extending end of the telescopic mechanism 5 is hinged with the turnover plate 6; the bottom of the overturning rack 3 is provided with two buffer cylinders 7 matched with the girder baffle plate 8, the extending ends of the buffer cylinders 7 penetrate through the table top of the overturning rack 3, and the two buffer cylinders 7 are respectively arranged at two ends of the girder baffle plate 8; the bottom of the overturning rack 3 is provided with a guide post 2, and the guide post 2 penetrates through the movable middle plate 10; and a pushing cylinder 4 corresponding to the girder baffle plate 8 is arranged on the overturning rack 3, and the pushing cylinder 4 is used for tightly pushing and fixing the girder workpiece 11.
