Description
Technical field
The utility model belongs to spindle blade servicing unit field, especially relevant with a kind of spindle bearing disassembling device.
Background technology
As shown in figure 1, spindle blade 1 ' is threaded onto in wharve 2 ', the bottom of spindle blade 1 ' passes the bottom of wharve 2 ', wharve 2 '
Bottom forms open cavity and is used to be set with bolster bearing 3 ', and very fast yet with spindle rotating ratio, bolster bearing is easy to damage,
But because the open cavity position for installing bolster bearing is narrow, how to change bearing turns into a problem.
Utility model content
For drawbacks described above existing for above-mentioned background technology, the utility model aims to provide a kind of convenient dismounting and will not be right
Spindle blade causes the spindle bearing disassembling device of damage.
Therefore, the utility model uses following technical scheme：A kind of spindle bearing disassembling device, it is characterized in that, including axle
Bearing sleeve, spindle blade fore-set, top cover, pressure bar and sleeve, it is provided for connecting the spiral shell of described pressure bar at the top of described top cover
Pit, the bottom of pressure bar are connected by screw thread with described screwed hole；The bottom of described top cover forms and has a diameter larger than institute
The circular hole of screwed hole is stated, the junction of circular hole and described screwed hole forms step end face, and described spindle blade fore-set installs fixation
In the upper portion of described circular hole and it is resisted against on the step end face, the bottom of described spindle blade fore-set is matched somebody with somebody with spindle blade
The hole of conjunction, the lower section of described circular hole are fixedly connected with described bearing holder (housing, cover)；The upper portion of described bearing holder (housing, cover) is formed
The cylindrical mounting portion coordinated with described circular hole, the outer peripheral face of the lower section of bearing holder (housing, cover) and its centre bore in upper end it is small,
Big tubaeform in lower end, the outer peripheral face of the lower section of bearing holder (housing, cover) be provided with it is a plurality of vertical arranged at equal intervals and with it is tubaeform
The gap of centre bore insertion, the inner hole wall of tubaeform centre bore are provided with the indent coordinated with the bolster bearing on spindle blade
Circular groove, the width of indent circular groove is equal with the height of bolster bearing, the periphery of the lower section of described bearing holder (housing, cover)
The described sleeve of surface cover dress, sleeve set is on the outer peripheral face of bearing holder (housing, cover) and can move up and down.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
Described pressure bar is provided with handrail.
At the bottom margin for the centre bore that described indent circular groove is opened in bearing holder (housing, cover) the lower section.
It can reach following beneficial effect using the utility model：Bearing holder (housing, cover) of the present utility model is open type horn mouth zero
Part, can moving up and down by sleeve, adjust bell-mouthed diameter, when sleeve is moved to the top, horn mouth diameter is maximum,
More than bolster bearing diameter.By bearing holder (housing, cover) along spindle blade toward bearing direction insert, until bolster bearing enter bearing holder (housing, cover) groove in,
By sleeve toward drop-down, now bell-mouthed diameter is less than bearing diameter, and bearing holder (housing, cover) can embrace bearing.Pressure bar and top cover are spiral shell
Line connects, and by rotation, pressure bar can promote spindle blade fore-set.Because bearing is embraced, spindle blade can not be followed to move, when spindle blade quilt
When spindle blade fore-set slowly promotes, bearing will be ejected.Bolster bearing can easily be entered by structure of the present utility model
Row dismounting, spindle blade will not be also damaged when removing bearing.

Fig. 1 is the mounting structure schematic diagram of spindle blade.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is detaching structure schematic diagram of the present utility model.
Fig. 4 is the structural representation of bearing holder (housing, cover) of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As Figure 1-Figure 4, the utility model includes bearing holder (housing, cover) 5, spindle blade fore-set 3, top cover 2, pressure bar 1 and sleeve 4, top
The top of set 2 is provided for connecting the screwed hole of pressure bar 1, and the bottom of pressure bar 1 is connected by screw thread with screwed hole, pressure bar
1 is provided with the handrail for rotating support；The circular hole for having a diameter larger than screwed hole formed on the bottom of top cover 2, circular hole and screwed hole
Junction forms step end face, and spindle blade fore-set 3, which installs, fixes in the upper portion of circular hole and be resisted against the step end face
On, the bottom of spindle blade fore-set 3 and the hole of the cooperation of spindle blade 1 ', the lower section of circular hole are fixedly connected with bearing holder (housing, cover) 5；Bearing holder (housing, cover) 5
Upper portion forms the cylindrical mounting portion coordinated with circular hole, and the outer peripheral face of the lower section of bearing holder (housing, cover) 5 and its centre bore are in
It is tubaeform that upper end is small, lower end is big, the outer peripheral face of the lower section of bearing holder (housing, cover) 5 be provided with it is a plurality of vertical arranged at equal intervals and
With the gap 6 of tubaeform centre bore insertion, the inner hole wall of tubaeform centre bore is provided with and the bolster axle on spindle blade 1 '
The indent circular groove 7 of 3 ' cooperations is held, indent circular groove 7 is opened in the bottom margin of the centre bore of the lower section of bearing holder (housing, cover) 5
