Description
Technical field
The utility model relates to positioner, especially crankcase blank positioning fixture.
Background technology
The position that cylinder block bottom is used for installing bent axle is called crankcase, when being processed, crankcase blank need to use positioning fixture, fixture is the important component part of manufacturing system, no matter be tradition manufacture, or manufacturing system now, fixture is all very important, the former method that blank is processed is normally equipped with a cover in the relevant position of fixture, in dress workpiece, putting of bearing-surface boss line-up jig, then oil cylinder clamps, start processing, but this also exists a problem, be exactly blank be foundry goods, the size identical property of bearing-surface boss is bad, therefore, the blank bearing-surface boss of some batch can not be filled in the cover the inside of fixture.So before this, my company has added the operation that one boss harnessed an animal to a cart, together with marking.But have like this problem of existence, front road will process two procedures, marking, boss is harnessed an animal to a cart, and processing beat is slow.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of crankcase blank positioning fixture simple in structure, easy to use.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: crankcase blank positioning fixture, comprise base plate, be located at some cylindrical sleeve on base plate, be enclosed within straight pin in cylindrical sleeve, be located at jig plate on base plate, be located at the positioning seat that is fixed by screw on jig plate, be located at supporting seat on jig plate, be located at composite bush on positioning seat, be located at holder on supporting seat, be located at elasticity key seat on holder, be located at the positioning sleeve being connected and fixed by bolt on elasticity key seat, described elasticity key seat bottom is provided with spring.
As preferably, in described elasticity key seat, be provided with shaft block ring, be provided with shaft block ring and can fix the axially-movable of elasticity key seat.
As preferably, on described straight pin, be connected with handle, be provided with handle and can control the tightness of straight pin in cylindrical sleeve.
As preferably, described composite bush is provided with dust ring, can effectively avoid entering of dust by dust ring.
As preferably, described straight pin is demountable structure, is used to complete the rear demolition and maintenance of conveniently carrying out, and novel structure is flexible.
Beneficial effect:
The utility model has adopted technique scheme that crankcase blank positioning fixture is provided, and has made up the deficiencies in the prior art, reasonable in design, sound construction, and reliable operation, operating efficiency is high, easy to operate, reduces potential safety hazard, uses safety.
