During work, bevel gear work piece nails on location with involute profile in supporting, when pull bar is moved to the left, drives three pressing plates bevel gear work piece to be compressed, can carry out inner hole grinding processing by connecting plate; When pull bar moves to right, the roller on pressing plate rolls along the inclined-plane on support plate, pressing plate is opened outward, unclamps bevel gear work piece.
Structure of the present invention is simple, processing ease, and utilize the accurate locating cone gear workpieces of supporting nail, pressing plate firm grip bevel gear work piece, convenient and swift simultaneously, substantially increases production efficiency, reduce cost.
Further, pedestal right-hand member is provided with annular boss, annular boss cylindrical and chuck left end Internal hole positioning, accurate positioning, chuck left end is circumferentially with screwed hole, and on pedestal, corresponding position is provided with through hole, pedestal firmly can be connected with chuck by screw, facilitate installing/dismounting.
Further, supporting nail is six, and extension arm is three, accurate positioning, and clamping firmly.
Further, pull bar right-hand member is provided with positive stop lug boss, from positive stop lug boss smooth section, thread segment successively to the right on pull bar, connecting plate endoporus can be enclosed within smooth section, thread segment attaching nut, tightening nut to connecting plate end face is against on boss and can be fixed on pull bar by connecting plate, facilitates installing/dismounting.
Further, gripper shoe is circumferentially with the fairlead of socket pressing plate, and fairlead not only can play guide effect to pressing plate, but also can prevent pressing plate from departing from gripper shoe.
Further, pedestal is circumferentially with six installing holes, is conveniently arranged on lathe or workbench by fixture.
