Workpiece conveying device

The invention discloses a workpiece conveying device which comprises a conveying device body, a supporting mechanism, a fixed clamping mechanism and a movable clamping mechanism. One or more sets of supporting mechanisms are installed in the middle of the conveying device body and used for supporting workpieces. A fixed clamping mechanism and a movable clamping mechanism are installed on the left side and the right side of the conveying device body respectively and used for clamping and fixing the two ends of a workpiece respectively. The problem that the distance between the two sides of a workpiece deviates is solved, the workpiece is completely fixed, meanwhile, a plurality of sets of workpieces are in an interference-free free clamping state, the defects of deformation, collision and the like generated in the transportation process due to insufficient rigidity of a middle connecting part of the workpiece are overcome, and the difficult operation of follow-up loading is eliminated; and meanwhile, the probl
