Specific embodiment
The utility model provides many applicable creative concepts, which can be reflected in a large number of specifically
Context in.The specific embodiment described in following the embodiments of the present invention is only used as the tool of the utility model
The exemplary illustration of body embodiment, without constituting the limitation to the scope of the utility model.
The utility model will be further described with specific embodiment with reference to the accompanying drawing.
As shown in FIG. 1, FIG. 1 is the sides that a kind of elastic ferrule of preferred embodiment of the utility model and cambered surface bushing cooperate
View.The present embodiment is a kind of elastic ferrule 1 of cambered surface bushing grinding, when cambered surface bushing 2 is ground, the arc lining
The insertion elastic ferrule 1, the elastic ferrule 1 are fixed it with the arc bushing 2 using tension in set 2, common to join
With grinding process, 2 stress equalization of arc bushing both can control accurate dimension, also guarantee that the arc bushing 2 will not fly
Out, safety is improved.
As shown in Figures 2 and 3, wherein Fig. 2 is the bottom view of elastic ferrule shown in Fig. 1；Fig. 3 is elastic ferrule shown in Fig. 2
Along the cross-sectional view of line A-A.The elastic ferrule 1 includes isometrical weighted areas 11 and elastic ferrule area 12.
The isometrical weighted areas 11 is cylindrical, section in step-like, including in a ring the first plug 111 and
Second plug 112 axially extending from first plug 111, second plug 112 are connected with the elastic ferrule area 12
It connects.The isometrical weighted areas 11 is designed as step-like, and the top of the arc bushing 2 resists the first of the isometrical weighted areas 11
Plug 111 avoids the arc bushing 2 that axial float occurs in Grinding Process, and stability is more preferable.
The outer diameter of the isometrical weighted areas 11 is identical as the outer diameter of the cambered surface bushing 2, the isometrical counterweight in grinding
The outer diameter in area 11 directly participates in grinding process, and 2 stress equalization of cambered surface bushing can both guarantee size, will not lead to it
It flies out, better reliability.
