Utility model content
For solving the problems referred to above, the utility model proposes a kind of crankcase blank positioning fixture, it uses location, bottom, location, side, drift angle side and location, top, and position fixing process Automatic Control, and positioning precision is high, and position fixing process is easy.
Crankcase blank positioning fixture of the present utility model, including base；Hole, location, multiple bottom it is provided with on described base；Outwards it is embedded with the thimble of ⊥ type by base inside hole, location, described bottom；Between thimble and hole, location, the bottom inner face of described ⊥ type, elastic component is installed；Described thimble bottom surface is provided with cylinder；Promoting thimble by cylinder so that it is being embedded in hole, blank location, after completing location, cylinder shrinks, by elastic component effect, thimble returns in hole, location, bottom；Lateral pneumatic head part is installed on described base；It can carry out location, side to crank shaft blank；Being provided with bent axle blank drift angle detent mechanism at described base corner, after completing location by bent axle blank drift angle detent mechanism, carry out side and location, bottom surface, its positioning precision is high, it is simple to be processed.
Further, described bent axle blank drift angle detent mechanism is installed on the outer avris of base corner, and blank drift angle and side can be carried out synchronizing location by it.
Further, described bent axle blank drift angle detent mechanism includes pedestal, and described pedestal is provided with both-end cylinder；Described both-end cylinder two ends be provided with the first location wave and second location wave.
Yet further, wave and be pressed in bent axle blank drift angle end face in described first location；Wave and be pressed in bent axle blank drift angle side in described second location.
Further, described Lateral pneumatic head part includes side cylinders；Described side cylinders telescopic end is fixed with side thimble.
As preferred embodiment, described base top surface is provided with side positioning strip, and its auxiliary carries out Primary Location.
This utility model is compared with prior art, crankcase blank positioning fixture of the present utility model, it is automatically positioned by thimble, Lateral pneumatic head part and bent axle blank drift angle detent mechanism, during location, first carry out drift angle side and location, top, then carry out bottom and side positions, position fixing process Automatic Control, positioning precision is high, and position fixing process is easy.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is of the present utility model to state bent axle blank drift angle detent mechanism structural representation.
