Abstract

The invention discloses a shaft end drilling device. The shaft end drilling device is characterized in that a radial through hole is formed in the lower part of a base with a vertical cavity; a tubular screw rod is mounted in the through hole; a push-pull rod is mounted in the screw rod; the outer end of the push-pull rod extends outside the outer end of the screw rod, and a stopper is provided; the inner end of the push-pull rod extends outside the inner end of the screw rod, and is positioned in the cavity of the base; the inner end of the push-pull rod is in shaft connection with an upper connecting rod and a lower connecting rod; the lower end of the lower connecting rod is connected with the bottom of the cavity; and a mold pushing block is mounted at the upper end of the upper connecting rod. The shaft end drilling device solves the problem of difficult guarantee of the drilling perpendicularity in axial drilling of workpieces by a drill bit during rotating, and is particularly suitable for machining of small holes at the shaft ends of columnar workpieces.

Description

technical field [0001] The invention relates to the field of machining, in particular to a device for machining axial small holes on the shaft end of a cylindrical workpiece. Background technique [0002] Present shaft-end drilling method all adopts fixed workpiece, and drills axially to workpiece while rotating by the drill bit. The disadvantage is that it is difficult to ensure the verticality of the drilling when the drill bit works under two dynamic conditions, and it is easy to break the drill bit. Contents of the invention [0003] The invention provides a drilling device for moving the workpiece in order to solve the problem that it is difficult to ensure the verticality of the drilling hole when the drill bit axially drills the workpiece while rotating. [0004] The technical solution of the present invention is a shaft end drilling device, which is special in that a radial through hole is left in the lower part of the base with a vertical cavity, and a tubular sc...
