To the problems referred to above; The utility model provides a kind of grip device that is used for thin-wall tube-shaped part hole milling processing; It exists in the time of solving existing thin-wall tube-shaped part hole milling processing and loading clamp, and clamping is complicated, inefficient problem, can effectively guarantee the precision and the crudy of the hole milling processing of thin-wall tube-shaped part simultaneously.
Its technical scheme is such; It comprises base plate; Said base plate is installed on the milling machine workbench, it is characterized in that: it comprises rotating shaft, piece-holder structure and indexing means, is fixed with pedestal on the said base plate; Said rotating shaft is passed said pedestal and is installed on said pedestal through bearing and axial limiting mechanism, in the said rotating shaft, the both sides that are positioned at said pedestal are separately installed with said piece-holder structure and said indexing means.
It is further characterized in that:
Said axial limiting mechanism comprises both sides end cap and stop collar, and said bearing press-fits in said pedestal through said both sides end cap, and the indexing means installation end of said rotating shaft is set with stop collar, and said stop collar is through locking nut one axial compression;
Said piece-holder structure comprises location-plate, expansion set and tapered sleeve; Said location-plate passes through bolt in said rotating shaft; The said location-plate outside, said rotating shaft periphery are set with said tapered sleeve; Through locking nut two axial restraints, said expansion set is set in said tapered sleeve periphery between said tapered sleeve and the said rotating shaft, and the inner peripheral surface of said expansion set cooperates with the outer peripheral face taper seat of said tapered sleeve;
Said indexing means comprises the stepper motor that electricly connects with switch board, and said stepper motor is installed on said base plate through pedestal, and the output shaft of said stepper motor is connected with said rotating shaft through hitch bar; Said hitch bar comprises stepper motor terminal pad and rotating shaft terminal pad; Said stepper motor terminal pad all is connected with said stepper motor output shaft, rotating shaft through flat key with the rotating shaft terminal pad, and said stepper motor terminal pad is connected through bolts and nuts with said rotating shaft terminal pad.
Adopt the utility model to be used for the grip device of thin-wall tube-shaped part hole milling processing; Its beneficial effect is: its by the base plate integral installation on the milling machine table face; Piece-holder structure and indexing means all are installed in the rotating shaft; Workpiece directly carries out the calibration location by the clamping of piece-holder structure and by indexing means, so its clamping workpiece is convenient, the location is reliable, can effectively improve working (machining) efficiency; When carrying out clamping, workpiece directly is set in the expansion set periphery and by location-plate and locking nut two axial location; Locking nut two promotes tapered sleeve vertically to the location-plate side shifting in axial locking, because all taper seats cooperate in tapered sleeve periphery and the expansion set, thereby the promotion expansion set is radially with the workpiece swelling; It can guarantee fully contacting of expansion set and workpiece internal face; Piece-holder is reliable, and can effectively reduce the clamping deformation of workpiece, improves the rigidity of workpiece processing; Reduce the influence of processing vibration, improve workpiece machining accuracy and crudy workpiece; And stepper motor carries out automatic indexing, has improved indexing accuracy greatly, has further guaranteed machining accuracy.
