Utility model content
Order of the present utility model there are provided a kind of output shaft of gear end face drilling equipment being convenient to output shaft of gear clamping and centering.
For reaching this object, the utility model by the following technical solutions:
A kind of output shaft of gear end face drilling equipment, comprise output shaft of gear and locating piece, the gear of described output shaft of gear one end is provided with odd number first gear teeth, the top axle of described locating piece is to being arranged with locating hole, the hole wall of described locating hole is axially evenly distributed in the first teeth groove, described first teeth groove and described first gear teeth matched in clearance; And the end face of the other end of described output shaft of gear is axially preset with centre bore, when drill bit insertion centre bore carries out reaming, under the effect of the chip power of described drill bit, described drill bit and described centre bore complete automatic centering.
Wherein, the hole depth of described locating hole is 2 to 3 times of described gear thickness.
Wherein, the gap between described first gear teeth and described first teeth groove is less than or equal to 0.2mm.
Wherein, the bilateral symmetry of described locating piece offers straight wall easy for removal and installation.
Wherein, the bottom of described locating hole is provided with for the fastening installing hole of described locating piece.
Wherein, described output shaft of gear and described gear are that powder metallurgy die is one-body molded.
Wherein, described centre bore and described output shaft of gear are formed in one.
The beneficial effects of the utility model: the utility model comprises output shaft of gear and locating piece, the gear of described output shaft of gear one end is provided with odd number first gear teeth, the top axle of described locating piece is to being arranged with locating hole, the hole wall of described locating hole is axially evenly distributed in the first teeth groove, described first teeth groove and described first gear teeth matched in clearance; And the end face of the other end of described output shaft of gear is axially preset with centre bore, when drill bit insertion centre bore carries out reaming, because the first teeth groove in locating hole and the first gear teeth are set to matched in clearance, therefore when drill bit inserts centre bore, be subject to the effect of drill bit chip power, output shaft of gear entirety adjustment can make centre bore and drill bit automatic centering automatically, and namely the axle center of end-face hole and the axle center of drill bit overlap, and the utility model is convenient to output shaft of gear clamping and centering.
