Description
Technical field
The utility model relates to a kind of centering elastic expanding fixture, it is mainly used in processing thin wall cylinder cover field on lathe.
Background technique
Cylinder jacket is typical thin-wall part, and processing quality directly influences the service performance of diesel engine, especially in smart car
Outer circle, end face and end face seam allowance dimensional accuracy and geometric accuracy are critically important.Processing cylinder jacket outer circle is frequently with hydraulic bullet at present
Property ringfeder and mechanical type elastic expansion-sleeve.But their manufacturing costs are high, and the tensioner amount of fixture is small, and applicable cylinder jacket aperture size is small,
Use scope is small.
Utility model content
Cylinder jacket smart car process manufacturing procedure is concentrated technical problem to be solved by the utility model is: providing one kind, is mentioned
High processing efficiency reduces the centering elastic expanding fixture of Fixture Design cost of manufacture.
Centering elastic expanding fixture described in the utility model, including mandrel and elastic expansion-sleeve, mandrel include conical head and cone
Handle, the conical head that elastic expansion-sleeve inner cavity corresponds to mandrel are set as taper sheath, and elastic expansion-sleeve is sleeved on conical head, conical head and bullet
Property ringfeder miner diameter end between by the connection of the adjusting component that can move to axial, bullet is distributed on the side wall of elastic expansion-sleeve
Property hole.
The adjusting component includes stud, nut and gasket, and gasket is sleeved on stud, stud one
End is connected through a screw thread mandrel, the groove of the end setting setting-up piece of elastic expansion-sleeve, and the other end of stud passes through nut
Fastening.
The springhole is set as strip springhole, and there is circular through hole at the both ends of strip springhole.
The springhole is located at both ends and the medium position of elastic expansion-sleeve, and the springhole at both ends runs through elastic expansion-sleeve
End.
The setting of springhole is easy to implement the elasticity of elastic expansion-sleeve, improves tensioner amount.Mandrel, elastic expansion-sleeve and adjusting component
Setting, make this fixture while positioning and tensioner function, concentrate manufacturing procedure, improve processing efficiency and quality.
The beneficial effects of the utility model are:
The advantages of absorption of fission formula elastic expansion-sleeve structure, solves the deficiency that Split type flexible ringfeder uses, and designs monoblock type
Elastic expansion-sleeve redesigns fixture other component, optimizes clamp structure, realizes that process is concentrated in processing, achievable outer circle,
End face and end face seam allowance are processed on a procedure.

Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1 to 4, centering elastic expanding fixture described in the utility model, including mandrel and elastic expansion-sleeve 4, core
Axis includes conical head 2 and taper shank 1, and the conical head 2 that 4 inner cavity of elastic expansion-sleeve corresponds to mandrel is set as taper sheath, and elastic expansion-sleeve 4 is set with
On conical head 2, connected between conical head 2 and the miner diameter end of elastic expansion-sleeve 4 by the adjusting component that can be moved to axial,
Springhole 9 is distributed on the side wall of elastic expansion-sleeve 4.Adjusting component includes stud 6, nut 7 and gasket 5, and gasket 5 is sleeved on
On stud 6,6 one end of stud is connected through a screw thread mandrel, the groove of the end setting setting-up piece 5 of elastic expansion-sleeve 4
8, the other end of stud 6 is fastened by nut 7.Springhole 9 is set as strip springhole, the both ends of strip springhole
There is circular through hole.Springhole 9 is located at both ends and the medium position of elastic expansion-sleeve 4, and the springhole 9 at both ends runs through elastic expansion-sleeve
4 ends.
In use, 4 bedding-in of elastic expansion-sleeve is filled on the conical head 2 of mandrel, it is solid by washer, stud 6, nut 7
It is fixed, the taper shank 1 of mandrel is inserted into tapered bore of machine tool spindle, it, will be on the fixed lathe of tooling by the self-locking function of taper.
When workpieces processing, by cylinder jacket 3 on elastic expansion-sleeve 4, with 3 Internal hole positioning of cylinder jacket, in 3 left end of cylinder jacket
One locating piece is set, realizes that positioning function is moved to the left elastic expansion-sleeve 4 and tensioner with adjustable wrench nutting 7, thus real
Now to the fixation of cylinder jacket 3.
