Description
Technical field
The utility model belongs to machinery field, relates in particular to a kind of vehicle thin-wall sleeve internal clamp.
Background technique
Vehicle thin-wall sleeve internal clamp, the processing applied to cylinder-shaped thin wall cover parts inner hole.It usually uses in the prior art
Chuck carrys out direct clamping cylinder-shaped thin wall cover parts, is easy to make part deformation and become waste product.
Utility model content
The utility model provides a kind of vehicle thin-wall sleeve internal clamp, solves the direct clamping workpiece of chuck in background technique
It is easy the shortcomings that making part deformation and becoming waste product.
The technical solution of the utility model is achieved in that a kind of vehicle thin-wall sleeve internal clamp, including clamp body, described
The cone of clamp body is equipped with external conical sleeve, and it is solid by nut that external conical sleeve is equipped with thrust ball bearing, thrust ball bearing and external conical sleeve
Fixed connection, nut are screwed on the screw thread of clamp body simultaneously, and holding screw, the cylindrical end of holding screw are equipped in the threaded hole of nut
It protrudes into the annular groove of external conical sleeve, external conical sleeve is equipped with sealing ring and is packed into nut bore, and external conical sleeve is equipped with dust board, passes through
Screw is fixed on nut, and ejection screw is equipped in the threaded hole of clamp body；
Preferably, the external conical sleeve is equipped with dust board, and dust board is fixed by screws on nut.
Preferably, radial slot is provided in the cone of the clamp body.
The beneficial effects of the utility model are: the utility model positioning clamping accuracy is high, excircle of workpiece surface uniform force,
Deflection is small.The clamp structure is simple, at low cost, and reliability, stability are good, easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the B-B direction diagrammatic cross-section of the utility model Fig. 1；
Fig. 3 is the C-C of the utility model to diagrammatic cross-section.
Part explanation: 1, chuck, 2, clamp body, 3, nut, 4, ejection screw, 5, external conical sleeve, 6, thrust ball bearing, 7, tight
Determine screw, 8, sealing ring, 9, dust board, 10, workpiece.
Specific embodiment
For a better understanding and implementation, being further described with reference to the accompanying drawing to the utility model: a kind of vehicle thin-walled
Internal clamp is covered, by external conical sleeve 5 in the cone of clamp body 2, on external conical sleeve 5,3 sets of nut are pushing away thrust ball bearing 6
It on power ball bearing 6 and external conical sleeve 5, and is screwed on the screw thread of clamp body 2, cylinder end clamping fixed screw 7 is screwed into the threaded hole of nut 3
Interior, the cylindrical end of cylinder end clamping fixed screw 7 protrudes into the annular groove of external conical sleeve 5, but does not hold out against external conical sleeve 5, enables external conical sleeve 5
It is freely rotated.8 sets of sealing ring on external conical sleeve 5 and are packed into 3 hole of nut, 9 sets of dust board on external conical sleeve 5 and are fixed on
On nut 3.Ejection screw 4 is screwed into the threaded hole of clamp body 2.Fixture assembling finishes.
Frictional force between nut 3 and external conical sleeve 5 can be reduced with thrust ball bearing 6, reduces external tapered sleeve when tightening nut 3
5 torques generated improve the precision that positioning clamps to reduce the deformation of 2 upper cone of clamp body.
Iron filings and dust are blocked with dust board 9, the damage of iron filings and dust to sealing ring 8 is reduced, prevents iron with sealing ring 8
Bits enter in thrust ball bearing 6 with dust, protect thrust ball bearing 6.
It is provided with radial slot in the cone of clamp body 2, the cone inner hole of clamp body 2 generates elasticity and receives under the extruding of external conical sleeve 5
Contracting, to clamp workpiece.
The claw of chuck 1 slightly clamps clamp body 2, plug will be examined to be packed into 2 hole of clamp body, tightening nut 3 makes fixture
Body 2, which clamps, examines plug, and rotation examines plug, checks its circular runout, adjusts clamp body 2, makes to examine the same of plug and main shaft
Axis degree meets the requirements, and then, the claw clamping device body 2 of chuck 1 unclamps nut 3, removes inspection plug.
Workpiece 10 is put into 2 hole of clamp body, tightening nut 3, drives thrust ball bearing 6 to be moved to the left with external conical sleeve 5, outside
The cone surface of the internal taper hole extrusion clamp body 2 of tapered sleeve 5, makes the inner hole elastic shrinkage of clamp body 2, to clamp workpiece 10.When
Workpiece 10 after processing is completed, unclamps nut 3, and nut 3 drives cylinder end clamping fixed screw 7 that external conical sleeve 5 is pushed to move right, external conical sleeve
Generate gap between 5 and the circular conical surface of clamp body 2, clamp body 2 affranchises shape and size under state, to unclamp workpiece
10, workpiece 10 is removed by hand.It if there is gapless between individual pieces 10 and the inner hole of clamp body 2, can not remove, just use by hand
Spanner rotation ejection screw 4 ejects workpiece 10.
Using the fixture, workpiece deformation is small, and positioning clamping accuracy is high, and reliability, stability are good, easy to operate.
