Description
Technical field
The present invention relates to field of fixtures, and in particular to a kind of aeroelasticity self-centering casing vehicle clamper.
Background technology
For similar small-sized axial flow fan（Fig. 1）The die castings such as casing, its dimensional accuracy is not high and draw taper can not
Avoid, thus it must be met by finishing processing for its bearing chamber or seam and the high accuracy cooperation of bearing or stator core will
Ask.In general, die casting uses cast aluminium alloy gold（Or kirsite, magnesium alloy）Deng fragile material, retaining part intensity is met too
Difference or chucking power are too big, may result in casing deformation or even ftracture.So, exploitation is with the express dispatch type casing for meaning
Vehicle clamper will be helpful to improve production efficiency and product qualification rate, and to the processing to similar thin-walled parts product, with one
Fixed expansion application value.
The content of the invention
The technical problem to be solved in the present invention is that the defect for overcoming prior art is directed to casing class workpiece there is provided one kind, or
Fixture used in the processing of similar thin-wall product, the fixture good clamping effect can slow down or even avoid workpiece because bearing clamping
The drawbacks of easily permanent deformation even ftractures after power.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of aeroelasticity self-centering casing vehicle clamper, including：
Clamp body, it has clamp body body and sleeve, and the sleeve has chuck cavity, and the chuck cavity has taper

The fixation wall of cylinder；
Chuck, is at least partly placed in the sleeve；It has the outer cone wall that outside dimension increases successively from left to right,
And holding chamber, the holding chamber, outer cone wall and the chuck cavity are coaxial；The chuck also has from the right openings end of holding chamber
The gap extended to axial direction, the gap includes at least two be circumferentially all provided with along the outer cone wall；The chuck is applied
During with pulling force to the left, the width in the gap diminishes, and holding chamber is pointed to its internal workpiece clamp clamp force increase, to the folder
When head imposes pulling force to the right, the width in the gap becomes big, and holding chamber is pointed to its internal workpiece clamp clamp force and reduced.
It is preferred that, the clamp body also has limiting section, and the limiting section limits the maximum row that the chuck is slided to the left
Journey.
It is preferred that, the limiting section includes the first limited wall extended downwardly from internal chamber wall end, and from the left of outer cone wall
The second limited wall that end is extended downwardly, when the chuck slides into ultimate range to the left, first limited wall and described
Two limited walls are in contact.
It is preferred that, the internal chamber wall, outer cone wall are the splicing of truncated cone, frustum of a pyramid shape, or the frustum of a cone and the frustum of a pyramid
Body.Pyramid bench-type includes but is not limited to rotationally symmetrical Rhizoma Sparganii frustum, tetragonous cone table, pentagonal pyramid platform etc..Above-mentioned spliceosome refers to edge
The splicing of axial direction.
It is preferred that, the gradient of the internal chamber wall and the outer cone wall is 10 ゜.
It is preferred that, the clamp body body, sleeve and the chuck are single element.
It is preferred that, the gap includes four be circumferentially all provided with along the outer cone wall.
It is preferred that, the fixture is connected with pneumatic means, and the pneumatic means drives the chuck to horizontally slip.
The beneficial effect that the present invention is reached：
When being processed using the fixture of the present invention to workpiece, including procedure below：The positioning and clamping of 1 workpiece：Workpiece
Load and accommodate intracavitary, opened due to chuck outer rim and be all provided with least two gaps, when power set pull chuck to the left, its outer cone wall exists
While slip along the internal chamber wall of chuck cavity, gap width diminishes, chuck cavity opening（Right openings end）Radially tighten up and by work
Part is held tightly；2 processing：The workpiece of above-mentioned clamping is processed；3 demoulding pickups, after machining, power set drive chuck right
Move, with the elastic recovery of chuck（Gap width becomes big, and chuck cavity opening is radially loosened）, take out workpiece, time processing cycle
Just accuse and complete.
This fixture obtains just right clamping force using adjustable aerodynamic force, can also avoid scroll chuck from clamping because of spiral shell
Rotation clamping force is whard to control and causes workpiece to be permanently deformed；Chuck has both positioning and clamping function simultaneously, for such as Fig. 1 institutes
The thin-walled parts for being difficult to clamp shown, axial tightening power is developed into radial clamping force by this fixture, almost along whole（Circle）The conical surface
Clamp the outer rim of casing.Good clamping effect, slows down or even avoids workpiece being easily permanently deformed or even ftractureing after chucking power because bearing
The drawbacks of.
