A kind of special fixture at axle sleeve endoporus processing " O " shape oil groove, it comprises base, be mounted slidably the anchor clamps main shaft on base, the knife bar of fixedlying connected with anchor clamps main shaft same axis, first trace that is fixedly connected with the lathe spindle chuck, be connected with first trace and with first sector gear of the coaxial setting of anchor clamps main shaft, second sector gear that is meshed with first sector gear, first sector gear is identical with the second sector teeth number, be fixedly connected with gear cover plate on second sector gear, depart from its axial line place on the gear cover plate and be rotatably connected to an end of second trace, the other end of this second trace is rotatably connected to connecting rod, connecting rod and anchor clamps main shaft are fixedly connected, and the axial line of the axial line of anchor clamps main shaft and lathe spindle chuck coincides.
Preferably, described first trace departs from the axial line setting of lathe spindle chuck, and first trace is connected with first sector gear by first connecting rod.
The axial line of described first trace parallels with the axial line of anchor clamps main shaft, and the axial line of the axial line of first connecting rod and anchor clamps main shaft is perpendicular.
Offer regulating tank on the described gear cover plate, an end of second trace is rotatably connected to dwang, and this dwang inserts in the described regulating tank and is positioned at an interior position of departing from the gear cover plate axial line of regulating tank.
It axially offers chute described anchor clamps main shaft upper edge, is inserted with the spline pin that is connected with base in the chute.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
When the lathe spindle chuck drove the workpiece rotation, two identical sector gears of the number of teeth were driven to rotate, and further drove knife bar and make back and forth movement, make endoporus form " O " shape oil groove naturally, its process is simply quick, and " O " shape oil groove that processes is smooth smooth and easy, and yield rate reaches 100%.
