Abstract

The utility model relates to a deep hole drilling machine. The deep hole drilling machine is composed of a machine body, an inverted drill, a clamp, an ejection rod and a transmission mechanism. A guide rail, a drill connection platform, an ejection rod connection platform, a fixed upper platform, a fixed lower platform and a fixed workpiece platform are arranged on the machine body, wherein the drill connection platform and the ejection rod connection platform move vertically along the guide rail, and the fixed workpiece platform is placed between the drill connection platform and the ejection rod connection platform. The transmission mechanism is provided with a main shaft transmission mechanism, a clamp transmission mechanism, an ejection rod transmission mechanism and a feeding transmission mechanism. The structure that the drill stands upside down, rotates and feeds, and a workpiece can only rotate relative to the drill is adopted, therefore drill bit rotation speeds are reduced under the condition of the same machining efficiency, centrifugal force of cuttings is reduced, friction force with hole walls is reduced, the cuttings can be discharged at the speed close to the speed of free fall, heat dissipation of a drill bit is effectively improved, abrasion is reduced, and service life is prolonged. Synchronous relative rotation of the drill and the workpiece enables cutting positions to be changed into circumferential rotation change from being fixed, and axis skewing and vibration are eliminated; and forward-backward traction of the feeding mechanism is synchronous with vertical displacement, and therefore vertical still of the drill in the process of feeding is guaranteed.
