Abstract

The invention relates to a cutter sharpening technology of a gun drill and particularly relates to a cutter sharpening device of the gun drill. According to the invention, the problem that the traditional cutter sharpening device of the gun drill cannot mill a rear cutter face of a main cutting edge of the gun drill into a spiral face is solved. The cutter sharpening device of the gun drill comprises a base; the base is horizontally provided with a first rotating shaft; an inner and outer angle dial is horizontally arranged at the middle part of the first rotating shaft in a penetrating manner and a second rotating shaft is vertically arranged at the center of the inner and outer angle dial in the penetrating manner; a sleeve support is vertically arranged at the upper end of the second rotating shaft in the penetrating manner; an inner and outer angle locking handle is connected with the lower end of the second rotating shaft; a main shaft graduated disk is arranged at the front end of the outer side wall of the sleeve support; a main shaft sleeve is sleeved on the inner side wall of the sleeve support; a V-shaped positioning block is fixedly arranged at the front end of the inner side wall of the main shaft sleeve; and a cam and a feeding hand wheel are sleeved at the back end of the side wall of the main shaft sleeve. According to the invention, based on a brand-new structure, the problem that the traditional cutter sharpening device of the gun drill cannot mill the rear cutter face of the main cutting edge of the gun drill into the spiral face is effectively solved, sothat the cutter sharpening device of the gun drill is applicable to carrying out cutter sharpening on the gun drill.

Description

technical field [0001] The invention relates to a gun drill sharpening technology, in particular to a gun drill sharpening device. Background technique [0002] As the main means of precision deep hole machining, gun drilling is used more and more. During the use of the gun drill, it is inevitable to encounter the problem of re-sharpening the gun drill. Due to the complex geometry of the gun drill and the high requirements for angle and dimensional accuracy, manual grinding is difficult to meet the requirements. It is necessary to use a special gun drill sharpening device to grind the gun drill that meets the requirements, so as to bring out the full potential of the gun drill. Advantage. Generally, the flank of the main cutting edge of the gun drill is flat. Compared with the gun drill whose flank is helical, the heat dissipation area is small and the service life is short. However, the existing gun drill sharpening device can usually only grind the flank of the main cut...
