Abstract
The utility model provides a technical proposal of a large diameter deep hole jacking pole, mainly comprising a hollow jacking pole body. One end of the jacking pole body is provided with a jacking head with a cutting tool bit, and the other end of the jacking pole body is provided with a jacking pole feeding head. The technical proposal is characterized in that an inner pole is arranged in the inner cavity of the jacking pole body, the inner pole on one end of the jacking head is provided with a centre supporting stand with a butt material tip, the centre supporting stand contacts the inner wall of the jacking pole and can move or rotate relatively to the jacking pole, and the other end of the inner pole is provided with an inner pole supporting head. In addition, the jacking pole feeding head is provided with a cutting fluid inlet, the butt material tip can coaxially rotate on the centre supporting stand, the inner pole threads the jacking pole feeding head and moves relatively to the jacking pole feeding head, and the centre supporting stand is further provided with a liquid-passing hole.
Description
Affiliated technical field:
The utility model relates to the cutting element that machining is used, especially a kind of large diameter, deep borehole jacking bar.
Background technology:
In the prior art, known jacking bar all is a minor diameter, generally also is made up of cover stub bar, the hollow jacking body of rod and jacking bar feed head, on the cover stub bar cutting tool is arranged, and jacking bar feed head and feed arrangement are connected to the jacking bar feeding power is provided.The weak point that this jacking bar exists is that the material core diameter of extracting is less, can not be re-used as minor diameter jacking blank and use, and therefore, the waste of material that jacking is used is bigger.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and a kind of large diameter, deep borehole jacking pole technology scheme is provided.
This programme is realized by following technical measures: mainly include the hollow jacking body of rod, the cover stub bar of band cutter tip is housed at an end of the jacking body of rod, and jacking bar feed head is housed at the other end of the jacking body of rod, the characteristics of this programme are that the inner chamber at the described jacking body of rod also has an interior bar, the tip holder of band liftout point is housed on the interior bar of the first end of jacking, this tip holder contacts with jacking bar inwall, and can relatively move or rotate bar supporting member in the other end of interior bar is equipped with the jacking bar.The concrete characteristics of this programme also have, and on described jacking bar feed head the cutting fluid import are arranged.But described liftout point coaxial rotation on tip holder.Bar passes jacking bar feed head in described, and can relatively move with jacking bar feed head.On described tip holder, also has liquid pass hole.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be that inner chamber at the major diameter jacking body of rod also has an interior bar in this scheme, there are tip holder and interior bar supporting member in the two ends of bar in being somebody's turn to do, tip holder and cover stub bar homonymy, also be equipped with on it can with the liftout point of interior bar coaxial rotation.When work, the tight processed jacking blank in liftout pinnacle, interior bar supporting member can be by the top support of tailstock tool, and bar is coaxial with the jacking bar in guaranteeing.When jacking, the jacking blank rotates, the jacking bar feed, because the jacking core has the support of interior bar, so vibration or swing can not appear in the jacking core in the jacking process, can guarantee the complete of the precision of jacking processing and jacking core, the jacking blank that makes the jacking core still can be used as minor diameter is used, make the jacking blank material improve utilization rate, also saved material simultaneously.In addition, on jacking bar feed head, the cutting fluid import is arranged, liquid pass hole is arranged on tip holder, like this when work, cutting fluid is entered by the cutting fluid import, by gap between the jacking body of rod and the interior bar and the liquid pass hole on the tip holder, just can enter the cover stub bar and cool off, guaranteed the cutting of cover stub bar.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.
1 is the cover stub bar among the figure, and 2 is the liftout point, and 3 is the jacking body of rod, and 4 is tip holder, and 5 is interior bar, and 6 is the cutting fluid import, and 7 is jacking bar feed head, and 8 is interior bar supporting member, and 9 is liquid pass hole.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the large diameter, deep borehole jacking bar of this programme, include the hollow major diameter jacking body of rod (3), the cover stub bar (1) of band cutter tip is housed at an end of the jacking body of rod (3), and jacking bar feed head (7) is housed so that be connected with the feed arrangement of lathe at the other end of the jacking body of rod (3), for the jacking bar provides feeding power.Inner chamber at the described jacking body of rod (3) also has an interior bar (5), end on interior bar (5) is equipped with the tip holder (4) of band liftout point (2), liftout point (2) tip holder (4) go up and can with coaxial the relatively rotating of tip holder (4), this tip holder (4) contacts with the jacking body of rod (3) inwall, and have and relatively move with the jacking body of rod (3) inwall or rotate movingly, tip holder (4) then with cover stub bar (1) in the same side.Bar supporting member (8) can keep coaxial with bar (5) in guaranteeing when working with the jacking bar in order to support interior bar (5) in the other end of interior bar (5) is equipped with.In described bar (5) also with the coaxial jacking bar feed head (7) that passes of the jacking body of rod (3), and can relatively move movingly with jacking bar feed head (7).In addition, cutting fluid import (6) is arranged on described jacking bar feed head (7), go up liquid pass hole (9) in addition in described tip holder (4), this can guarantee that cutting fluid can be entered by cutting fluid import (6), by gap between the jacking body of rod (3) and the interior bar (5) and the through cover of the liquid pass hole (9) on the tip holder (4) stub bar (1), the cutting of cover stub bar (1) can normally be carried out.
Claims (5)
