Abstract
The invention discloses a drawing device for a bearing outer ring and a blind hole lining. The drawing device comprises a barrel body connected with a rotating rod, wherein a bolt M30 and a nut M30 which is matched with the bolt M30 and is provided with a circular truncated cone are arranged at the center of the end surface of the barrel body in a penetrating manner; an internal threaded hole M12 is formed in one end, which is located outside the barrel body, of the bolt M30, and a large threaded hole communicating with the internal threaded hole M12 is formed in the other end of the bolt M30; the bolt M30 is connected with a long bolt M12 and a nut M12 matched with the long bolt M12 through the internal threaded hole M12; a square bolt structure M30 serving as a wrench is formed on the outer surface, which is located between the nut M30 and the nut M12, of the bolt M30; one end of the long bolt M12 is a cone, and the other end of the long bolt M12 is provided with a boss with a cross groove. The drawing device can timely and effectively remove the bearing outer ring and the blind hole lining, so that the lathe repairing time is shortened, the labor intensity of a worker is relieved, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of draw-off gear, more particularly to a kind of bearing outer ring and blind hole bushing drawing
Device.
Background technology
Often there is bearing damage in lathe Jing and bearing outer ring is remained in housing, the liner wear of blind hole is needed
Change the problem for being difficult to take out.Delay is caused produce situations such as to occur because of such case in order to reduce,
And then bring bigger loss, a kind of draw-off gear is needed, dismounting bearing outer ring and blind is efficiently solved
The problem that hole bushing is wasted time and energy.
The content of the invention
It is an object of the invention to overcome the problem above that prior art is present, there is provided a kind of bearing outer ring
With blind hole bushing draw-off gear, bearing outer ring and blind hole bushing can be timely and effectively dismantled.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is by the following technical programs
Realize：
A kind of bearing outer ring and blind hole bushing draw-off gear, including the cylinder being connected with rotating bar,
The body end surface center is through being provided with a M30 bolts and the M30 with round platform being matched therewith
Nut, one end that the M30 bolts are located at outside cylinder are provided with M12 internal thread holes, the other end be provided with
The major thread hole that M12 internal thread holes are communicated, the M30 bolts are connected with by M12 internal thread holes
One M12 stay bolts and the M12 nuts being matched therewith, the M30 bolts be located at M30 nuts and
Outer surface between M12 nuts forms the four directions of the M30 as spanner bolt arrangement, the long spiral shell of the M12
One end of bolt be cone, the other end be provided with band cross recessed boss.
Further, pad is provided between the M12 nuts and M30 four directions bolt arrangement.
The invention has the beneficial effects as follows：
The present invention can timely and effectively dismantle bearing outer ring and blind hole bushing, when shortening lathe repairing
Between, the labor intensity of workman is reduced, work efficiency is improve.
Description of the drawings
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the one of the application
Part, the schematic description and description of the present invention are used to explain the present invention, do not constitute to this
Bright improper restriction.In the accompanying drawings：
Fig. 1 is a kind of structural representation of embodiment of the present invention；
Label declaration in figure：1- cylinders, 2- rotating bars, 3-M30 bolts, 4-M30 nuts, 5-M12
Stay bolt, 51- cones, 52- boss, 6-M12 nuts, 7-M30 four directions bolt arrangement, 8- pads,
9- bearing outer rings.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in figure 1, a kind of bearing outer ring and blind hole bushing draw-off gear, including with rotating bar 2
The cylinder 1 being connected, at 1 end face center of the cylinder through be provided with a M30 bolts 3 and with its phase
The M30 nuts 4 with round platform for coordinating, one end that the M30 bolts 3 are located at outside cylinder 1 are provided with
M12 internal thread holes, the other end are provided with the major thread hole communicated with M12 internal thread holes, the M30
Bolt 3 is connected with a M12 stay bolts 5 and the M12 spiral shells being matched therewith by M12 internal thread holes
Female 6, the M30 bolts 3 are located at the outer surface between M30 nuts 4 and M12 nuts 6 and form use
Make the M30 four directions bolt arrangement 7 of spanner, one end of the M12 stay bolts 5 is cone 51, another
End is provided with band cross recessed boss 52.
Further, pad 8 is provided between above-mentioned M12 nuts 6 and M30 four directions bolt arrangement 7.
The operation principle of the present embodiment is as follows：
During uses, first M30 bolts 3 are passed through from cylinder 1, M30 nuts 4 are taken, make round platform and
In 1 end face of cylinder, M12 internal thread holes form gap and coordinate, then M12 stay bolts 5 from band boss
52 one end are put into simultaneously precession in the big internal thread hole of M30 bolts 3, until from M12 internal thread holes one
End is exposed, M12 nuts 6 of screwing on, that is, complete the assembling of draw-off gear of the present invention.
When bearing outer ring 9 is pulled out, according to internal diameter size dextrorotation M12 nuts 6 so that the boss of lower end
52 constantly open in the presence of cone 51, until being fully contacted with 9 internal diameter of bearing outer ring, then dextrorotation
M30 nuts 4 so that move on M30 bolts 3, so as to bearing outer ring 9 is taken out of；In dismounting blind hole
During bushing, as the typically no step of bushing is available for utilizing, just with appropriate power dextrorotation M12 nuts 6,
So that boss 52 is compressed with bushing, then dextrorotation M30 nuts 4, bushing can be taken out.The present invention has
Solve the problems, such as to effect that dismantling bearing outer ring and blind hole bushing wastes time and energy.
