[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0017] like Figs. 1-2 As shown, an embodiment of the utility model provides an upper and lower workpiece mechanism of a CNC deep hole boring machine, comprising: a main frame 1, a lifting cylinder 2, a lifting frame 3 and a conveying roller 4; a plurality of lifting cylinders 2 are linearly installed on the main frame 1, a lifting frame 3 is provided at the driving end of the lifting cylinder 2, and a plurality of conveying rollers 4 are linearly provided on the lifting frame 3.

[0018] The main frame 1 is installed between the two external pipe storage racks, allowing the furnace pipes placed on these racks to be rolled onto the conveyor rollers 4. The lifting frame 3 raises the furnace pipe workpiece to the same height as the lifting rollers of the external boring machine, allowing the furnace pipe to be conveyed to the boring machine via the conveyor rollers 4. When the lifting frame 3 is lowered, it is lower than the pipe storage racks without affecting the lateral rolling conveyance of the furnace pipes.
