Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 is refer to, Fig. 1 is a kind of structural representation for the swollen height regulating device that the utility model embodiment provides.
In a kind of embodiment, the swollen height regulating device, including nut 10 and the spiral shell for being socketed in gag lever post 30
Bolt 20, the upper outside face of the bolt 20 are provided with screw thread 21, and the nut 10 passes through the screw thread 21 and the bolt 20
Screw thread 21 connects, and the nut 10 passes through the change in location on the bolt 20, the swollen height of adjustment electric tube expander main body.
The nut 10 being arranged on by using instead on gag lever post 30, it is simple in construction, by changing nut 10 relative to gag lever post
30 position, swollen top adjustment is carried out using the rotation and lifting of screw thread 21, avoid remodel every time be required for it is repeated multiple times by bolt 20
Tighten, unscrew caused by waste of time, improve regulation efficiency and degree of regulation, reduce working strength, it is simple to operate.
The downside of the bolt 20 in the utility model is provided with through hole, and the bolt 20 passes through the through hole and institute
It is affixed to state gag lever post 30.The quantity of the through hole, dimensional parameters are not specifically limited during this is practical.
The cross section of the nut 10 can be regular polygon, pass through spanner rotating nut 10, the height of adjusting nut 10.
The utility model is not specifically limited to the cross section of nut 10, the cross section of nut 10 can be regular polygon or
It is circular.
If the cross section of nut 10 is circle, or it is other can not be by the shape of spanner rotating nut 10, can be with
By being provided with least one through hole in the side wall of the nut 10, through hole is inserted into one end of swing handle, you can to nut
10 position is adjusted.
The regulation to the swollen high higher precision of electric tube expander is realized by using nut 10 in the utility model, but even if
It is to be obtained by using the operator of nut 10 than existing higher degree of regulation, but still can not obtains specific height and become
Change.To obtain the exact position of nut 10, the surface of screw thread 21 is provided with the vertical graduated scale of vertical direction.By observing spiral shell
Female 10 starting and the change of final position, you can obtain the exact position of nut 10, obtain the swollen top adjustment of higher precision.
It is pointed out that in the utility model, to the quantity of the vertical graduated scale, set-up mode, distribution and
Vertical graduated scale is not specifically limited in itself, and vertical graduated scale can be the graduated scale of length, as using millimeter as least unit
Graduated scale.It is to determine due to the type of electric tube expander in general tube expansion, only a limited number of kind, therefore vertical graduated scale can also
It is demarcation model graduated scale, i.e., corresponds to a tube expansion height model in the graduated scale of a certain height.
Further to improve tube expansion precision, the surface of screw thread 21 is additionally provided with least one circumferential graduated scale, by
The surface of screw thread 21 sets circumferential graduated scale, with reference to vertical graduated scale, can use the principle of micrometer caliper, obtains higher swollen
Top adjustment precision.
The utility model to the circumferential graduated scale in itself and set-up mode is not specifically limited.
It is pointed out that using vertical graduated scale and circumferential graduated scale when, it is necessary to one reference, can be with transversal
On the basis of certain a line of face for the nut 10 of regular polygon, it can also be marked with the indentation being arranged on nut 10 or other references
Benchmark is designated as, the utility model is not especially limited to this.
Due to being adjusted using nut 10, although precision is high, adjustable range is small.Further to expand swollen top adjustment model
Enclose, existing swollen top adjustment side can be combined.Therefore the swollen height regulating device also includes being arranged on the gag lever post 30
Bolt 20 clamps regulating member, and the bolt 20 clamps regulating member by the bolt 20 and the gag lever post 30 is affixed.
Regulating member is clamped using existing bolt 20 and carries out coarse adjustment, is then carried out using the nut 10 in the utility model
Fine setting, improves swollen top adjustment precision.Certainly, existing bolt 20, which clamps regulating member, can predefine an adjusting range,
Adjustment is all that such as regulation is adjusted with 5cm endorsement multiple every time, so on the basis of at least one adjustment length every time
It is finely adjusted afterwards with nut 10.
It is pointed out that the utility model is not specifically limited to the height of the screw thread 21 of the nut 10, to described
The thickness of nut 10 is also not specifically limited.
In addition, the utility model embodiment additionally provides a kind of electric tube expander, including gag lever post and is arranged on the limit
Swollen height regulating device as described above on the bar of position.
Because the electric tube expander has swollen height regulating device as described above, therefore also have and the swollen height regulating device
Top adjustment effect that identical is swollen.
Electric tube expander in the utility model is generally vertical pipe expander, if it is desired that with horizontal type tube expanding machine, can also do phase
Corresponding adjustment, obtains identical technique effect, and the utility model is not especially limited to this.
In summary, the electric tube expander and swollen height regulating device that the utility model embodiment provides, are arranged on by using instead
Nut on gag lever post, it is simple in construction, by changing position of the nut relative to gag lever post, carried out using screw thread rotation lifting swollen
Top adjustment, avoid every time remodel be required for it is repeated multiple times bolt is tightened, unscrew caused by waste of time, improve regulation
Efficiency and degree of regulation, working strength is reduced, it is simple to operate.
Electric tube expander provided by the utility model and swollen height regulating device are described in detail above.Herein should
Principle of the present utility model and embodiment are set forth with specific case, the explanation of above example is only intended to help
Assistant solves method and its core concept of the present utility model.It should be pointed out that for those skilled in the art,
