The purpose of the utility model is to provide a kind of bearing extractors, to solve above-mentioned technical problem.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of bearing extractor, disassembly seat and mandril bolt including frame shape；The lower plate setting of the disassembly seat
The bearing bayonet of notch shape dismantles the upper plate setting through-hole of seat and corresponding through-hole fixed setting nut, mandril bolts and nuts
It is threadedly engaged and passes through through-hole and be arranged；Mandril bolt include spiro rod section and be integrally disposed upon spiro rod section end means；
Tool bearing snap-gauge jaggy is detachably arranged in the upper surface corresponding shaft bearing bayonet of lower plate；The notch of bearing bayonet is greater than bearing
The notch of snap-gauge.
Technical solutions of the utility model further improvement lies in that: bearing bayonet be semicircular indentations.
Technical solutions of the utility model further improvement lies in that: means perpendicular to spiro rod section be arranged.
Technical solutions of the utility model further improvement lies in that: bearing snap-gauge is fixed using screw and lower plate.
Technical solutions of the utility model further improvement lies in that: the lower end of mandril bolt setting diameter is greater than outside spiro rod section
The pad of diameter.
By adopting the above-described technical solution, the technical effect that the utility model obtains has:
The utility model after use, can make disassembly bearing more convenient, can without beaing the i.e. detachable bearing of bearing
To play the role of protecting bearing, the protective effect to equipment can also be played.The utility model is particularly suitable for small space
Interior bearing removal.
The utility model is provided with bearing snap-gauge, by the way that the bearing snap-gauge of different size is arranged, can expand the tool
Use scope, is directed to the bearing snap-gauge of different bearing replacing different models, which set tool adaptation difference
The ability of standby bearing gets a promotion.
The utility model makes to dismantle that bearing is simple and convenient, speed is fast, and a people can be carried out operating, time saving and energy saving, gently
Just flexibly, comprehensive service performance is good.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the utility model:
The utility model discloses a kind of bearing extractors to be particularly suitable for narrow work for dismantling to bearing
Make the bearing removal in space.Here is specific embodiment:
The bearing extractor of the utility model, as shown in Figure 1 and Figure 2, disassembly seat 1 and mandril bolt including frame shape
2.Specifically, disassembly seat 1 is made of the structure of frame shape 4 blocks of steel plates, mandril bolt 2 is for applying external force.
The disassembly seat 1 of the utility model has upper plate 1-2 and lower plate 1-1, and notch shape is arranged on lower plate 1-1
Bearing bayonet 1-3, for blocking bearing when dismantling bearing.Through-hole is set in the upper plate 1-2 of disassembly seat 1 and corresponding through-hole is solid
Top plate nut 5 is set surely, mandril bolt 2 and top plate nut 5 are threadedly engaged and passes through through-hole setting.Mandril bolt 2 and top
Crab bolt 5 is threadedly engaged, and can be moved by rotating mandril bolt 2 in the position of vertical direction.Axis in the utility model
It holds bayonet 1-3 and is traditionally arranged to be semicircular indentations.It is specific as shown in Figure 1, Figure 3.
As shown in Figure 1, mandril bolt 2 include spiro rod section 2-1 and be integrally disposed upon the end spiro rod section 2-1 means 2-
2.The setting means 2-2 of mandril bolt 2 is more convenient when being to rotate force.In specific implement, means
2-2 is arranged perpendicular to spiro rod section 2-1.Further, in the lower end of mandril bolt 2, setting diameter is greater than spiro rod section 2-1 outer diameter
Pad 4 is arranged in the lower end surface of spiro rod section 2-1 in pad 4, because the diameter of pad 4 is bigger, when supporting with stress face contact not
It is easily damaged stress surface.
In specific implement, the utility model is further, in the upper surface corresponding shaft bearing bayonet 1-3 of lower plate 1-1
Bearing snap-gauge 3 is set, and the bearing snap-gauge 3 has the notch consistent but of different sizes with bearing bayonet 1-3 shape.This is practical new
Type can preset the bearing snap-gauge 3 of multiple groups different size specification, the reality for the bearing then dismantled as needed when in use
Size selection bearing snap-gauge 3 in border is installed on lower plate 1-1.Bearing snap-gauge 3 in the utility model is detachably to be arranged, so as to
It is replaced；Bearing snap-gauge 3 can specifically be fixed using screw and lower plate 1-1.
The notch of the utility model middle (center) bearing bayonet 1-3 is greater than the notch of bearing snap-gauge 3, which can make bearing snap-gauge
3 work normally, and realize the effect of bearing snap-gauge 3.
The course of work of the utility model is as follows, firstly, the bearing bayonet 1-3 on the lower plate 1-1 for dismounting seat 1 is placed
In the inside of bearing 6, bearing 6 is located in bearing bayonet 1-3；Then, mandril bolt 2, the lower end of mandril bolt 2 and bearing are turned
Axis contact among 6 continues to turn mandril bolt 2 until slowly extracting bearing 6.Use state diagram is shown in Fig. 2.
The utility model expands the use scope of the tool, is directed to different bearings more by setting bearing snap-gauge
The bearing snap-gauge for changing different model, realizes the multi-purpose content of the bearing extractor.
After use, disassembly bearing is more convenient for the utility model, will not be to axis without beaing the i.e. detachable bearing of bearing
It holds and causes any harm, can play the role of protecting bearing, the protective effect to equipment can also be played.The utility model makes
Disassembly bearing is simple and convenient, speed is fast, and a people can be carried out operating, time saving and energy saving, light and flexible.The utility model can
Suitable for the bearing removal in the narrow device space.
The utility model structure is simple, easy to use, easy to operate, and operating rate is fast, and comprehensive service performance is good.
