Description
Technical field
It the utility model is related to technical field of tooling clamps, more particularly to a kind of bearing fixture.
Background technology
Bearing is a kind of common machine components, is often integrally fixed at the both ends of rotating shaft.In the assembling process of some bearings
In need to use hot assembly, hot assembly is that tight fit is changed into the installation side of loose fit by heating bearing using thermal expansion
Method.It is a kind of conventional and labour-saving installation method.This method is suitable to the installation of the larger bearing of the magnitude of interference, bearing or can before hot charging
The lasso of divergence type bearing is put into fuel tank uniformly 80-100 DEG C of heating, then takes out from oil and is attached to as early as possible on axle.Due to this
When bearing temperature it is higher, it is impossible to directly carry out human contact, it is necessary to be operated by fixture.
A kind of tension-type bearing fixture is disclosed in the Chinese utility model patent that notification number is CN204621889U, is wrapped
Mobile jib, fixture block are included, mobile jib side is provided with two pieces of supporting plates and the rotating shaft through two supporting plates, and rotating shaft one end is provided with rotation
Handle；Mobile jib is provided with threading hole, there is through hole on fixture block, and steel wire rope one end is fixed on mobile jib, and steel wire rope sequentially passes through some folders
Through hole and threading hole on block, the steel wire rope other end are fixed in rotating shaft.
This bearing fixture makes steel wire rope constantly be wrapped in rotating shaft, each fixture block and bearing are close by rotating handler
Contact, bearing is clamped on fixture, then carries out hot assembly work.During bearing shifts, in order to prevent fixture block from unclamping
Bearing, operator need hand-held handler to prevent it from rotating.Due to being difficult to keep stable by operator is hand-held, easily because helping
Dynamics change loosens fixture block, causes bearing to come off, and operator's labor intensity is big；On the other hand, mistake of the bearing in transfer
Gradually cooled down in journey, the diameter of bearing outer ring can reduce, and cause occur gap between fixture block and bearing, bearing easily comes off.

With right clamping piece 22 towards the left lateral movement of intermediate plate 21 1, until bearing is clamped.Because turbine and worm 72 has auto-lock function, even if
Operator's release handle 8, clamping part remain to keep clamp shaft to hold.
Due to fixture, when being used continuously a period of time, temperature can raise, in order to prevent user to be burned.Fix bar 1 is remote
Clamping part one end is provided with handle 11, handle 11 is grafting with fixed part, and handle 11 is using high-temperature resistance plastice or timber etc.
Heat-barrier material, reduce the conduction of heat.
The course of work of the present utility model and have the beneficial effect that：
During work, by rotational handle 8, worm screw 72 drives leading screw 6 to rotate by worm gear 71, and leading screw 6 passes through nut seat band
Movable slider 4 and right clamping piece 22 move, and the distance of left intermediate plate 21 and right clamping piece 22 is become big, bearing is placed in into left intermediate plate 21 and right folder
Between piece 22.Rotational handle 8, make right clamping piece 22 towards the left lateral movement of intermediate plate 21 1, until bearing is clamped.Due to turbine and worm
72 have auto-lock function, even if operator's release handle 8, clamping part remains to keep clamp shaft to hold.
When bearing, which gradually cools down race diameter, to be reduced, torsion spring 5 drives left intermediate plate 21, right clamping piece 22 towards bearing lateral wall
It is synchronized with the movement, block rubber 9 is close to bearing lateral wall all the time.Block rubber 9 increases rubbing between left intermediate plate 21, right clamping piece 22 and bearing
Power is wiped, avoids gap occur between left intermediate plate 21, right clamping piece 22 and bearing, bearing is not allowed easy to fall off.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
