Description
Technical field
It the utility model is related to cylinder jacket machining frock, especially a kind of thin wall cylinder cover lathe finish fixture.
Background technology
Because thin cylinder sleeve wall thickness is small, it is easy to become by the clamping force effect of fixture when smart car
Shape, influence the dimensional accuracy and form accuracy of thin wall cylinder cover.
The content of the invention
The purpose of this utility model is：A kind of thin wall cylinder cover lathe finish fixture is provided, when reducing thin wall cylinder cover smart car
Deformation, improve its dimensional accuracy and form accuracy.
Technical solution of the present utility model is：The thin wall cylinder cover lathe finish fixture includes mandrel, piston, elastic expanding
Set, bushing and bolt, the center of mandrel set centre bore, orthogonal radial hole are set on mandrel, and radial hole mutually passes through with centre bore
Logical, mandrel left end sets the shoulder hole of insertion centre bore, installs piston in shoulder hole, the center bore end of mandrel right-hand member is sealed with bolt
Close, elastic expansion-sleeve is sleeved on the outer wall of mandrel, and bushing is sleeved on the outer wall of elastic expansion-sleeve again, between mandrel and elastic expansion-sleeve
The cavity of closing is formed under the cooperation of piston and bolt, is full of fluidity filler in cavity.
Wherein, 22~26 deep trouths, 2~3mm of bottom wall thickness of deep trouth are circumferentially uniformly distributed on excircle of bushing face.
When work, thin wall cylinder cover is enclosed on bushing, push rod one end is connected with oil cylinder, and the push rod other end leans against work
Beyond the Great Wall；Fluidity filler is evenly distributed in clamping cylinder on thin-wall cylinder casing to the active force of elastic expansion-sleeve by the transmission of bushing
Set.
The utility model has the advantages that：One bushing is set on elastic expansion-sleeve, uniformly transfers hydraulic clip clamp force, clamping force
Be evenly distributed in cylinder jacket inner circle, cylinder jacket by clamping force influenceed caused by deformation it is small, significantly improve the deformation of cylinder jacket, essence
Vehicle Processing precision is high.
