Lifting device and machining equipment

The utility model discloses a lifting device and machining equipment. The lifting device comprises a rack, a bracket, a lifting mechanism and a conveying mechanism. The bracket is slidably connected with the rack in the first direction. The lifting mechanism comprises a linear driving part, a chain wheel rotationally connected with the moving end of the linear driving part and a chain wound around the chain wheel. One end of the chain is connected with the rack, and the other end of the chain is connected with the bracket. The linear driving piece drives the chain wheel to ascend and descend and can drive the bracket at the end of the chain to slide in the rack in the first direction. The lifting device can be in butt joint with the assembly line, and the tray flowing in is borne by the bracket. And then the bracket is driven by the lifting mechanism to ascend or descend in the first direction so as to be separated from the assembly line and then conveyed to an inlet of the assembly line in the second directi
