Abstract
The utility model discloses a kind of inner core to rise bar device, it includes clamping cylinder and expands chamber cone.One end of described clamping cylinder is set to hollow tubular, and the port around described tubular end is provided with multiple tracks slotted opening; Cone one end, described expansion chamber is provided with the tapered slope removing tip, and the little nose circle diameter in described tapered slope is less than internal diameter diameter of a circle on described hollow cylinder, and the large nose circle diameter in described tapered slope is greater than internal diameter diameter of a circle on described hollow cylinder.The little nose circle of described expansion chamber cone inwardly enters the hollow end of described clamping cylinder always, until tapered slope is by large for the support of the tubular end port of described clamping cylinder, thus reaches the effect from pipe fitting inner wall clamping.It is simple that the utility model has structure, is convenient to manufacture, and can not damage the advantages such as outer surface of tube wall.
Description
Technical field
The utility model relates to a kind of frock clamping, especially in regard to the fixture that a kind of pipe fitting inner wall clamps.
Background technique
Clamping now for cast part generally all adopts outside clamping, but because the outer tube wall of circle easily skids when outside clamping, not easily clamps, extruding clamping mode more energetically now will be adopted to clamp.But but this kind of mode easily causes damage to outer tube wall, thus make the required precision of outer tube wall cannot be up to standard, thus make pipe fitting become waste product.
Model utility content
The utility model proposes a kind of structure simple, be convenient to manufacture, the inner core that can not damage outer surface of tube wall rises bar device.
For solving the problems of the technologies described above, the utility model proposes following technological scheme: a kind of inner core rises bar device, it includes clamping cylinder and expands chamber cone.One end of described clamping cylinder is set to hollow tubular, and the port around described tubular end is provided with multiple tracks slotted opening; Cone one end, described expansion chamber is provided with the tapered slope removing tip, and the little nose circle diameter in described tapered slope is less than internal diameter diameter of a circle on described hollow cylinder, and the large nose circle diameter in described tapered slope is greater than internal diameter diameter of a circle on described hollow cylinder.The little nose circle of described expansion chamber cone inwardly enters the hollow end of described clamping cylinder always, until tapered slope is by large for the support of the tubular end port of described clamping cylinder, thus reaches the effect from pipe fitting inner wall clamping.
Rise as a kind of inner core described in the utility model the preferred version of bar device, and wherein said slotted opening is symmetricly set on described tubular end, such that its port is stressed can be even.
Rise as a kind of inner core described in the utility model the preferred version of bar device, the other end wherein clamping cylinder is provided with the cup dolly that diameter is greater than described clamping column diameter, the diameter of this cup dolly is greater than the diameter of institute's clamping pipe fitting, make it always outside suspension member, this inner core can be taken off easily and to rise bar device.
Rise as a kind of inner core described in the utility model the preferred version of bar device, wherein said clamping column body is provided with tapped hole, the little disc on the upper conical inclined-plane of cone, described expansion chamber is provided with match with described tapped hole stud, described expansion chamber cone reaches to clamping cylinder progresses inside by screwing stud, then supports the object of large tubular end port.
Rise as a kind of inner core described in the utility model the preferred version of bar device, the wherein said inner core bar device that rises is hard iron and steel material quality, use the clamping cylinder of hard iron and steel material quality can produce huge active force when the port micro-strain of tubular end, thus reach the effect of clamping pipe fitting.
The utility model compared with prior art, has following beneficial effect:
One, structure is simple, is convenient to manufacture, and can promote the use of on a large scale.
Two, clamping effect is good, and the distortion of iron and steel material quality brings huge clamping force.
Three, do not damage the outer surface of pipe fitting, make its outer surface precision higher, and not easily produce waste product.
Accompanying drawing explanation
Fig. 1 is that inner core described in the utility model rises the perspective view of clamping cylinder of bar device;
Fig. 2 is that inner core described in the utility model rises the perspective view of expansion chamber cone of bar device.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Referring to Fig. 1-3, the structure of what it was detailed describe a kind of inner core described in the utility model rises bar device.
In one embodiment, a kind of inner core of the utility model bar device that rises includes clamping cylinder 1, expands chamber cone 2 and base 3.Wherein, clamp cylinder 1 include one end be set to hollow tubular end 11, be symmetricly set on four road slotted openings 12 of tubular end 11 and be arranged on clamping column body tapped hole (not shown).Expand chamber cone 2 to include the tapered slope 21 of removing tip and be arranged on the stud 22 matched with tapped hole on the little nose circle of tapered slope 21.Base 3 is arranged on the other end of clamping cylinder 1, and its diameter is greater than the diameter of clamping cylinder 1.
Put clamping cylinder 1 into will clamp arranged at inner side of pipe fitting, then the little nose circle expanded in chamber cone 2 tapered slope 21 is entered the tubular end 11 of clamping cylinder 1, and by screwing stud 22 and tapped hole to reach tubular end 11 is supportted large object.The tubular end 11 be stretched then plays the effect of a clamping to pipe fitting.And the outer tube wall of pipe fitting can not be damaged while clamping.
In another embodiment, this inner core bar device that rises is all hard iron and steel material quality.Use iron and steel material quality can make it under small distortion, just obtain huge stress, thus ensure the dynamics of clamping.
