Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provides that a kind of positioning precision is high, convenient mounting and clamping, efficiently machining hole fixture.
Realizing the technical scheme that the utility model object adopts is, a kind of machining hole fixture, at least comprise the cylinder be fixed on platen, the top of cylinder is provided with locating support, locating support comprise location-plate and more than 2 be fixed on the support bar on location-plate lower surface perpendicular to location-plate, the piston rod of cylinder is vertical with location-plate, and the middle part of location-plate offers walks tool bore for cutter feed.
Walk in tool bore the alignment pin being provided with walking tool bore and match, alignment pin is installed on away in tool bore perpendicular to location-plate.
Described support bar is L-shaped, and the horizontal component of L shape support bar contacts with the workbench of lathe, and is fixed by screws on platen.
The center of location-plate offers through hole, and through hole is positioned at by tool bore.
Cylinder is provided with jacking block, and jacking block is fixed on the top of cylinder piston rod.
Workpiece is put between jacking block and location-plate, the position of adjustment workpiece makes the boss of workpiece be arranged in the through hole of location-plate, hole to be processed is positioned at below tool bore simultaneously, insertion alignment pin is located, cylinder intake, piston rod rises, location-plate and jacking block respectively with the upper and lower intimate surface contact of workpiece by Workpiece clamping.
The fixture tool that the utility model provides has the following advantages:
1, the fixture that the utility model provides is pneumatic pinch, the clamping force applied workpiece is little and workpiece is firm, relative displacement can not occur between workpiece and fixture when ensure that machining hole, during clamping work pieces, clamping force size is fixed and can regulate clamping force size according to actual needs;
2, the through hole offered by location-plate center of the fixture that provides of the utility model and alignment pin are positioned, and positioning precision is high, decreases finished product percent defective, remarkable in economical benefits;
3, the fixture that provides of the utility model with between workpiece for face contacts, the frictional force of contact area greatly therefore between fixture and workpiece is large, and workpiece can not move adding man-hour, guarantees the crudy in hole;
4, the fixture stroke that provides of the utility model is comparatively large, is applicable to each axis products, can not produce and crush, ensure that the surface quality of part during working shaft-like part to product surface;
