Abstract
The utility model belongs to the technical field of vertical lathes and relates to a boring rod structure, in particular to a boring rod applicable to a vertical lathe numerical control knife tower. The boring rod structure comprises a turret, a dovetailed groove is formed in the turret, and a lathe tool rest, a pressing block and a bayonet lock are sequentially arranged in the dovetailed groove from left to right. A bayonet lock chucking face is arranged on the connection portion between the bayonet lock and the pressing block, and a pressing block chucking face matched with the bayonet lock chucking face is arranged on the connection portion between the pressing block and the bayonet lock. The lathe tool rest is connected with the pressing block through a tightening bolt, and the upper end of the tightening bolt penetrates through a through hole in the lathe tool rest and is connected with a threaded hole in the pressing block. The back end of the lathe tool rest is connected with a boring tool rod through bolts. The boring rod structure is simple, compact and reasonable in structure, convenient to use, easy and fast to disassemble and assemble, and improves working efficiency.
