Part transport vehicle and transport system

The invention provides a part transport vehicle and a transport system, and relates to the technical field of transport. The part transport vehicle comprises a base, sliding grooves are formed in the positions, close to the front side and the rear side, of the upper end face of the base, and through grooves are formed in the positions, close to the front side and the rear end, of the two sides of the base. The transport vehicle is arranged on the multiple transport frames with the conveying guiding function, and the multiple transport frames can be stacked and arranged in the transverse conveying direction, the vertical direction and the vertical direction in an up-and-down layered mode according to needs, so that rapid conveying of machining and manufacturing of multi-variety and small-batch parts is achieved; automatic feeding and discharging of conveying and unmanned operation are achieved, the operation efficiency is improved conveniently, meanwhile, the arrangement mode of a conveying system can be chang
