The first telescopic rod includes a second sleeve 301 and a second slide bar 302. The second sleeve 301 and the second slide bar 302 are respectively connected to the supports 2 on both sides. The end of the second slide bar 302 is slidably installed on the inner side of the second sleeve 301. When the second power component drives the second telescopic rod to extend or retract, it drives the supports 2 on both sides to move closer or farther away from each other, thereby driving the automatic extension and retraction of the first telescopic rod; a plurality of self-locking universal wheels 6 are installed at the bottom end of the support 2.

[0027] The clamping frame comprises two clamping rods 4 and two second telescopic rods. The second telescopic rods comprise first sleeves 101 and first sliding rods 102, which are connected with the two clamping rods 4 respectively.

The second linear driving mechanism 11 is started to drive the rack 12 to move. The movement of the rack 12 can drive the gear ring 13 to rotate, and the rotation of the gear ring 13 drives the mounting shaft 10 and the clamping frame to rotate.

[0029] The first linear driving mechanism and the second linear driving mechanism are one of a gas cylinder, an electric push rod or a hydraulic cylinder.

[0030] Specifically, when the workpiece (a semi-trailer compartment door plate) is flanged, first, the device is moved to the workpiece position, the first linear drive mechanism 5 is started to drive the clamping frame to move downward, so that the workpiece is placed on the inner side of the clamping frame, then the second power assembly is arranged to drive the second telescopic rod to shorten, that is, to drive the two clamping rods 4 to approach each other, until the two clamping rods 4 on both sides are clamped with the workpiece, then the first power assembly is arranged to drive the two second telescopic rods to approach, so as to realize clamping of the other two sides of the workpiece. At this time, the four sides of the workpiece are clamped and fixed, the first linear drive mechanism 5 is started to drive the clamping frame to move upward, when the clamping frame moves to the upper end positioning position, the rotating drive assembly installed is driven to rotate the clamping frame by 180 degrees. After the turnover is completed, the clamping frame is driven to move to the bottom end position, and finally the fixation of the workpiece is released. After the workpiece is released, it falls to the original position. As described above, the technical scheme can realize rapid turnover of the door plate. During the whole process, the door plate does not need to be manually carried, and after the turnover, the door plate is still in the original position, thereby facilitating subsequent processing work. The clamping frame is arranged in a telescopic structure, so that it can be folded after the turnover work is completed. The clamping frame can be used for clamping and fixing workpieces of different sizes, and the workpiece is placed on the inner side, so as to reduce the probability of workpiece bumping.
