Abstract
A kind of expansion sleeve, including body, briquetting, spring ring, which is characterized in that the body is hollow cylindric, and concave slot is designed on body longitudinal direction, fluted one is designed in body transverse direction；The briquetting is designed as "convex" shaped, it is matched with the concave slot on body, the briquetting top surface centre position design fluted two, two both sides of groove are designed with the non-slipping block of protrusion, the briquetting is positioned in the longitudinal concave slot of body, can be up and down, spring ring is sleeved in the transverse concave groove one of body, and in the groove two being placed on briquetting.Utility model provides a kind of expansion sleeve, the stability of product is strengthened by the structure design of monoblock type, expansion sleeve effectively saves space using the structure of machinery, while also saves the consumption of the energy, and simple in structure, easy to operate, beautiful and generous.
Description
Technical field
The utility model is related to a kind of expansion device more particularly to a kind of expansion sleeves.
Background technology
In production and processing, it is necessary to when bearing is expanded, common expansion sleeve generally all uses gas currently on the market
Capsule expansion structure or block assembled structure, air bag expansion structure are high and complicated to the thickness requirement of expansion sleeve, during operation
It is also required in addition connect source of the gas；The stability of its structure of the structure of block assembly is poor, is not convenient to use；So it is badly in need of a kind of swollen
Expansion set solves the problems, such as these.
Utility model content
For existing technical deficiency, the utility model provides a kind of expansion sleeve.
To achieve these goals, technical solution adopted in the utility model is：A kind of expansion sleeve, including body, pressure
Block, spring ring, which is characterized in that the body is hollow cylindric, and concave slot is designed on body longitudinal direction, this
Fluted one is designed in body transverse direction；The briquetting is designed as "convex" shaped, is matched with the concave slot on body, the pressure
Block top surface centre position design fluted two, two both sides of groove are designed with the non-slipping block of protrusion, and the briquetting is positioned over body and indulges
, can be up and down in upward concave slot, spring ring is sleeved in the transverse concave groove one of body, and is placed in recessed on briquetting
In slot two.
Groove one in the transverse direction is located at the centre position of the upper concave slot in body longitudinal direction.
The concave slot at least two in same transverse direction, and symmetrically.
Expansion sleeve is placed on main axis of dilatation during specific implementation, makes the position alignment of briquetting on the expansion casting die of main axis of dilatation,
Briquetting is carried out by the expansion casting die of main axis of dilatation, outwardly against so as to fulfill expansion, when being not required to expansion, to cancel main axis of dilatation pressure
The pressure of part makes briquetting return by spring ring.
The beneficial effects of the utility model：The utility model provides a kind of expansion sleeve, is added by the structure design of monoblock type
The strong stability of product, expansion sleeve effectively saves space using the structure of machinery, while also saves the consumption of the energy,
And it is simple in structure, it is easy to operate, it is beautiful and generous.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of expansion sleeve, including body 1, briquetting 5, spring ring 4, which is characterized in that
The body 1 is hollow cylindric, and concave slot 3 is designed on 1 longitudinal direction of body, is designed in body transverse direction fluted
One 2；The briquetting 5 is designed as "convex" shaped, is matched with the concave slot 3 on body 1, the 5 top surface interposition of briquetting
It installs in respect of groove 26,26 both sides of groove are designed with the non-slipping block 7 of protrusion, and it is longitudinal that the briquetting 5 is positioned over body 1
, can be up and down in concave slot 3, spring ring 4 is sleeved in the transverse concave groove 1 of body 1, and is placed in recessed on briquetting 5
In slot 26.
Groove 1 in the transverse direction is located at the centre position of the upper concave slot 3 in 1 longitudinal direction of body.
The concave slot 3 at least two in same transverse direction, and symmetrically.
Expansion sleeve is placed on main axis of dilatation during specific implementation, makes the position alignment of briquetting on the expansion casting die of main axis of dilatation,
Briquetting is carried out by the expansion casting die of main axis of dilatation, outwardly against so as to fulfill expansion, when being not required to expansion, to cancel main axis of dilatation pressure
The pressure of part makes briquetting return by spring ring.
The beneficial effects of the utility model：The utility model provides a kind of expansion sleeve, is added by the structure design of monoblock type
The strong stability of product, expansion sleeve effectively saves space using the structure of machinery, while also saves the consumption of the energy,
And it is simple in structure, it is easy to operate, it is beautiful and generous.
