Application method is as follows：With the top 15 end centre bores for withstanding axle 6,11 pulling bearing outer rings of transporting persons or goods by cart are revolved counterclockwise using spanner
Turn conventional screw mandrel 9, just can realize the dismounting of axle and bearing.This process is believed that axle is maintained static, and bearing is in movement（Referring to accompanying drawing
8）.But for the small equipment in certain operations space, conventional drawing horse can not then play its function.Particularly with part
The situation that frequent dismounting causes shaft end facial disfigurement and cannot take out more is difficult to complete the function of pulling out axle.
The content of the invention
The technical problems to be solved in the utility model is：Offer is a kind of can be in narrow space, the situation of shaft end facial disfigurement
Under can more effectively complete the pulling shaft Shi Lama for pulling out s function, with solve deficiencies of the prior art part.
Solving the technical scheme of above-mentioned technical problem is：A kind of pulling shaft Shi Lama, including screw mandrel, pulling seat, screw mandrel and pulling seat
It is connected through a screw thread, also including sleeve and drawing point, the upper surface of sleeve is provided with locating slot, and the lower surface of sleeve is abutted in for solid
On the casing outer face of dead axle；Described pulling seat is embedded into the locating slot of sleeve upper surface；The bottom of described screw mandrel is successively
Through pulling seat and sleeve, and it is connected with the big end of point is drawn, draws the small end of point to be connected with the end of axle.
Further technical scheme of the present utility model is：External screw thread is equipped with the big end of described drawing point and small end；Institute
The screw mandrel bottom terminal ends stated are provided with screwed hole A, draw the big end of point to be connected with screwed hole A by screw thread；The end of described axle
Screwed hole B is provided with, draws the small end of point to be connected with screwed hole B by screw thread.
Further technical scheme of the present utility model is：Screw mandrel is left hand thread with the screw thread of pulling seat.
Due to using said structure, the pulling shaft Shi Lama of the utility model compared with prior art, with following beneficial effect
Really：
1. can more be effectively completed in the case of narrow space, shaft end facial disfigurement and pull out s function：
Because the utility model includes screw mandrel, pulling seat, sleeve and draws point, screw mandrel to be connected through a screw thread with pulling seat, sleeve
Upper surface is provided with locating slot, and the lower surface of sleeve abuts in the casing end face for fixing axle；Pulling seat is embedded into sleeve upper end
In the locating slot in face；The bottom of screw mandrel sequentially passes through pulling seat and sleeve, and is connected with the big end of point is drawn, and draws the small end and axle of point
End connects.When using, the dismounting of axle and bearing just may be implemented in using the spanner screw mandrel that turns clockwise, this process is believed that axle
Hold and maintain static, axle is in movement.Therefore, sleeve of the present utility model is bearing directly against on the outer face of the casing of fixing axle,
The function of pulling shaft is completed by being connected with shaft end by the drawing point of screw mandrel bottom, is held without putting in pulling shaft using transporting persons or goods by cart, from
And can more be effectively completed in the case of narrow space and pull out s function.
2. can more be effectively completed in the case of the facial disfigurement of shaft end and pull out s function：
Because the utility model includes screw mandrel, pulling seat, sleeve and draws point, screw mandrel to be connected through a screw thread with pulling seat, sleeve
Upper surface is provided with locating slot, and the lower surface of sleeve abuts in the casing end face for fixing axle；Pulling seat is embedded into sleeve upper end
In the locating slot in face；The bottom of screw mandrel sequentially passes through pulling seat and sleeve, and is connected with the big end of point is drawn, and draws the small end and axle of point
End connects.When using, the dismounting of axle and bearing just may be implemented in using the spanner screw mandrel that turns clockwise, this process is believed that axle
Hold and maintain static, axle is in movement.Therefore, the utility model is in pulling axis, due to being moved with the hand towards the normal undeformed one end of axle, because
This, this drawing Marko pulls out s function can more be effectively completed in the case of the facial disfigurement of shaft end.
3. reliability rational in infrastructure：
Because the utility model includes screw mandrel, pulling seat, sleeve and draws point, wherein screw mandrel is connected with pulling seat by left hand thread
Connect, be able to will not be unclamped and the connection for drawing point, thus the relatively more reasonable reliability of its structure when using spanner rotary screw.
4. the axle of different size is applicable to
The utility model is by supporting various sharp specifications of drawing, you can suitable for the end thread of supporting connection different size axle
Hole.
5. can realize multi-functional：
The utility model combines with conventional drawing horse and uses, and can not only realize the use function of conventional drawing horse, may be used also
S function is pulled out to realize more being effectively completed in the case of narrow space, shaft end facial disfigurement, so as to can realize multi-functional.
6. expense, both economical practicality are saved：
Ben Lama only by screw mandrel, pulling seat, sleeve and draws point to constitute, and structure is very simple, and manufacturing cost is relatively low, because and can be with
Draw horse to support the use with conventional in the case where the various production moulds of La Ma manufacturers are not changed, can easily realize many work(
Can, therefore many expenses can be saved, it is economic and practical.
