Description
Technical field：
The utility model is related to a kind of blind hole end bearing extractor.
Background technology：
There are many kinds, one during maintenance of equipment, the reason for bearing damage is a kind of very common failure, bearing damage
As in the case of, the bearing of damage is in through hole body, is directly tapped bearing internal external wall and is knocked out.But if bearing is in blind
In the body of hole, and retainer is damaged, and in the case that Internal and external cycle is disengaged, the outer ring for damaging bearing is difficult to take out, maintenance time
It is more long, influence production.If this bulk damage of embedded bearing is even more lost more than gain accidentally.
Utility model content：
To solve the deficiency in above-mentioned technical problem, the purpose of this utility model is, there is provided one kind can overcome above-mentioned
Defect, meets the blind hole end bearing extractor of use demand.
Blind hole end bearing extractor provided by the utility model, it is characterized in that, including jacking block, expansion sleeve, screw mandrel and solid
Fixed board, screw mandrel sequentially passes through jacking block, expansion sleeve and fixed plate；Described jacking block is frustum, and it is internally provided with and screw mandrel phase
The internal thread of matching；Expansion sleeve is cylindric, and one steel ring is welded in its tensioner part；A pair of ejection spiral shells are symmetrically arranged with fixed plate
Bolt.
The tightening part of described expansion sleeve is divided into the tensioner piece that polylith is separated from each other.
The beneficial effects of the utility model are：
Simple structure, easy to operate, maintenance cost is low, is applicable the dismantlement work of blind hole end bearing crust, and largest benefit is
Save maintenance time, it is ensured that body is not damaged, and cost of manufacture is cheap.
Brief description of the drawings
Below in conjunction with the accompanying drawings and implementation method the present invention is further detailed explanation：
Fig. 1 is the utility model structural representation；
In figure, 1, jacking block；2nd, expansion sleeve；3rd, screw mandrel；4th, fixed plate；5th, liftout bolt.
Specific embodiment
As shown in figure 1, blind hole end bearing extractor described in the utility model, it is characterized in that, including jacking block 1, expansion sleeve 2,
Screw mandrel 3 and fixed plate 4, screw mandrel 3 sequentially pass through jacking block 1, expansion sleeve 2 and fixed plate 4；Described jacking block 1 is frustum, inside it
It is provided with the internal thread matched with screw mandrel 3；Expansion sleeve 2 is cylindric, and one steel ring is welded in its tensioner part；It is symmetrical in fixed plate
It is provided with a pair of liftout bolts 5.The tightening part of described expansion sleeve 2 is divided into the tensioner piece that polylith is separated from each other.
As a example by taking out 6206 bearings, if bearing designation change, it is necessary to jacking block, expansion sleeve, screw mandrel, fixed plate etc.
Part dimension all changes, but structural principle is constant, specifically：
Jacking block by a diameter of 30mm 45# round steel machine toolings, height 40mm tapers are 60 cone, centrum centre drill
The internal thread of M10 is attacked in hole.Expansion sleeve is processed using the drill chuck of vertical drilling milling machine, the tensioner part welding upper of its expansion sleeve
Road steel ring, the diameter of steel ring is tried one's best and is approached with the draw-in groove for dismantling bearing outer ring, and ensures its weld strength.Purpose is to ensure to rise
The tensioner position of tight set ensures the contact area of maximum contact with the inside groove for damaging bearing crust.Screw mandrel by M10 carbon filament bar
Nut-welding with M10 is constituted, and the nut screw connection of mono- M10 of length about 150mm is used, and is easy to adjust tensioner dynamics.Fixed plate
A width of 120 × the 50mm of length is made by the steel plate cutting of thickness 8mm, middle part is the circular hole of ￠ 12, in 30mm, 90mm position long
The internal thread of M14 is attacked in drilling, and M14 bolts coordinate pull-out bearing endothelium.
When in use, nut, fixed plate, expansion sleeve, jacking block are assembled at screw mandrel fixing nut end one by one, by screw mandrel timing
Pin is screwed, and expansion sleeve is in micro, slight rising state, puts the outer intracutaneous of bearing of damage into, continues positive hour hands rotary screw, makes to rise
The tensioning portion of tight set and the bearing crust for damaging adjust fitness after coming into contact with, until all contacts, now should ensure that and rise
The fastening dynamics of tight set is tried one's best greatly.Finally rotated with the uniform positive hour hands in bolt both sides of M14, the bearing crust that will be damaged is pulled out.
It, to understand the utility model example, and is not to the utility model embodiment party that above-mentioned case study on implementation is only
The restriction of formula.To belonging to the obvious change or change still in the utility model that spirit of the present utility model amplifies out
Protection domain in.
