Description
Technical field
The present invention relates to device used in bearing is dismantled during a kind of maintenance of floor production line, and in particular to a kind of bearing is drawn
Pulling device, belongs to dismantling device technical field.
Background technology
Because of the bearing used in floor production line equipment, the overwhelming majority is light-duty bearing, and it is generally to be interference fitted to coordinate.It is former
It is hinged come the pulling claw of the bearing drawing device used with support, gap is larger, is difficult to be fixed on bearing periphery when in use,
Could be fixed sometimes for two personal synergics, and skewness can be produced during jackscrew stress so that bearing circumferencial direction by
Power is uneven, and pulling claw easily releases ejection when draw-off gear tightens stress, less efficient, there is potential safety hazard.
The content of the invention
The purpose of the present invention is aiming at drawbacks described above there is provided a kind of bearing drawing device, and its is simple in construction, safe and reliable
Go for the bearing removal of different-diameter.
To solve the above problems, the present invention provides vertical along its on a kind of bearing drawing device, including support plate, the support plate
Direction is provided with least three pulling claws and a vertical jackscrew, and the support plate is provided with screwed hole, and the vertical jackscrew is arranged on
In the screwed hole, on the support plate by center of circle interval homogeneous angular of the screwed hole along radial direction provided with several first
Guide groove, one end of the pulling claw is provided with claw, and the other end is provided with screw thread, and the end of thread of the pulling claw is oriented to through described first
Groove is simultaneously provided with the first wing nut on its top.
Further, the pulling claw is made up of extension pulling claw and lower pulling claw, and one end of the lower pulling claw is provided with the claw, separately
One end be provided with screw thread, the extension pulling claw be L-shaped, it include provided with the second guide groove adjustment arm and with it is described adjust arm it is vertical
Top set threaded installing arm, the end of thread of the lower pulling claw is through second guide groove and is provided with the on its top
Two wing nuts, the end of thread of the extension pulling claw passes through first guide groove and first butterfly is provided with its top
Nut.By increasing extension pulling claw, extension assembling form is formed, drawing diameter is extended, it is more extensive to be allowed to the scope of application, can
For cylindrical larger bearing or other cylindrical components such as belt pulley and sprocket wheel etc..
First guide groove and the second guide groove are included by shaping-orientation groove, in adjustment, pulling claw can wherein freely
Mobile, preset clearance is small, when being fixed on bearing periphery, vertical jackscrew first is reached into suitable position, then use wing nut one by one
The pulling claw is tightened, without using spanner, as long as wing nut is tightened can just cause each pulling claw stress equalization in place, at this moment again
Rotate vertical jackscrew pulling shaft to hold, in drawing process, jackscrew is not in skewness, it is ensured that safe and reliable, whole mistake
Journey only needs a people to complete.
Further, the top of the vertical jackscrew two adjusting nuts side by side, in use, when rotating top nut due under
The spacing of nut can move down the jackscrew, when rotating lower nut because the spacing of top nut can make the jackscrew
Move up.
Further, the top screw seat that can be slided along the vertical jackscrew is also equipped with the vertical jackscrew, the pulling claw
It is provided with screwed hole, the outer rim of the top screw seat and is laid with the rotatable horizontal jackscrew equal with the pulling claw quantity,
The screwed hole of each horizontal jackscrew from the corresponding pulling claw is passed through, in use, by rotating the level
Jackscrew can adjust the position of the pulling claw respectively, so that the claw of the pulling claw is reliably stuck in the outer ring of bearing, can be with
Avoid deviating from from bearing.
Further, in order to preferably position and power transmission, the lower end of the vertical jackscrew is taper.
Compared with prior art, technical scheme has advantages below：
The bearing drawing device that the present invention is provided, globality is preferably, simple to operation, in the absence of security risk, and guide groove is deposited
When causing carrying, stress point position is accurate, is not in skewness in whole loading process, is repaired with production scene
Preferably, constructor closes mechanical property requirements to versatility, overcomes the irrational aspect of original structure, and increasing horizontal jackscrew in addition can be with
Prevent that pulling claw is slipped from bearing during drawing.
