Description
Technical field
This utility model is related to the boring head field of boring machine, more particularly to a kind of flexible boring head structure.
Background technology
Heavy caliber thick wall seamless steel tube is in process, it is impossible to definitely alignment, therefore the steel pipe condition of delivery is in standard model
Enclose it is interior there is micro bending, due to being hot-working, inner surface more or less has some defects to heavy caliber thick wall seamless steel tube, in order to
Meet customer requirement, both at home and abroad not yet captured with eliminating defect and then becoming one in the uniform boring of the steel pipe internal-surface of " bending "
A difficult problem.The method mainly taken both at home and abroad at present is to increase allowance and the mesh for eliminating defect is reached using boring in rigid boring head
, if thickness of steel pipe is monolateral, that allowance is then multiplied, and increases income to enterprise's wound effect and brings heavy burden, has a strong impact on
The performance of enterprises is played.Especially under steel industry integrally stagnant overall situation, more such as avenge to the existence of seamless steel pipe enterprise
Plus frost.
Utility model content
The purpose of this utility model is the above-mentioned not enough and defect for prior art, there is provided a kind of flexible boring head knot
Structure, to solve the above problems.
The technical problem that this utility model is solved can employ the following technical solutions to realize：
Flexible boring head structure, it is characterised in that include：
First end and the coaxially connected flexible clutch of boring bar；
The first end boring head knife rest coaxially connected with the second end of the flexible clutch；
First end is coaxial with the second end of the boring head knife rest and the revolving sleeve that is rotatably connected, in the outer of the revolving sleeve
Wall be circumferentially provided with it is some to tensioner processing inside pipe wall elastic supporting member for supporting optical member；
Internal diameter of the external diameter of the flexible clutch, boring head knife rest and revolving sleeve less than processing pipe.
In a preferred embodiment of the present utility model, the flexible clutch is metallic membrane shaft coupling.
In a preferred embodiment of the present utility model, the elastic supporting member for supporting optical member is included being floated by elastic component and is arranged on
Support block on the outer wall of the revolving sleeve.
In a preferred embodiment of the present utility model, the support block is set to wedge surface away from one end of the boring bar
Structure.
As a result of technical scheme as above, this utility model can be accomplished to carry out steel pipe internal-surface with regard to song with curved
Uniform boring processing, allowance is greatly reduced, and work efficiency is greatly improved, and is enterprise's cost declining, carry benefit made it is larger
Contribution.
Description of the drawings
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is a kind of structural representation of embodiment of this utility model.
Fig. 2 is a kind of fundamental diagram of embodiment of this utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, under
Face is expanded on further this utility model.
The first end of part defined below is that is, inner, the second end is the one end away from boring bar, i.e., near one end of boring bar
Outer end.
Referring to a kind of flexible boring head structure 1000 shown in Fig. 1 and Fig. 2, including flexible clutch 100, boring head knife rest 200
With revolving sleeve 300, inner coaxially connected on boring bar 400, the flexible clutch 100 in the present embodiment of flexible clutch 100
For metallic membrane shaft coupling.The inner of boring head knife rest 200 is coaxially connected with the outer end of flexible clutch 100, boring head knife rest 200
Outer end is coaxial with the inner of revolving sleeve 300 and is rotatably connected.It is circumferentially provided with the outer wall of revolving sleeve 300 some to tensioner
In the elastic supporting member for supporting optical member 310 of processing inside pipe wall.The external diameter of flexible clutch 100, boring head knife rest 200 and revolving sleeve 300 is less than and adds
The internal diameter of work pipe 1, it is ensured that this utility model can be entered smoothly in processing pipe 1.
Elastic supporting member for supporting optical member 310 in the present embodiment is included being floated by elastic component 311 and is arranged on the outer wall of revolving sleeve 300
Support block 313 on groove 312, elastic component 311 can take disk spring.In order that elastic supporting member for supporting optical member 310 should tensioner again
Will be in the adjustable external diameter of certain limit to adapt to different pipe diameters, support block 313 is set to wedge surface knot away from one end of boring bar 400
Structure 313a.
Operation principle of the present utility model is as follows：
When this utility model enters processing pipe 1 inner chamber to work, support block 313 can in processing pipe 1 table tensioner and with
Processing pipe 1 rotates, and the flexibility of processing pipe 1 is effectively conveyed to into boring cutter mechanism, it is ensured that allowance is consistent.Can be by changing
Become the quantity or deformation quantity of elastic component 311, to adjust the support external diameter of support block 313, the range of accommodation 0 of support block 313～
70mm, while also ensuring that the energy tensioner of support block 313 on the processing inner surface of pipe 1.And flexible clutch 100 guarantee boring head with
There is certain amount of deflection between boring bar 400, revolving sleeve 300, the support block 313 upper and lower, left and right motor fitness in processing pipe 1 is added
The flexibility of work pipe 1, while also can be fastenedly connected with boring bar 400, in the progradation of boring bar 400, can make boring head with it is curved just
Bently uniform boring processing is carried out to processing table in pipe 1, allowance is greatly reduced, and work efficiency is greatly improved, be enterprise's drop
Cost, puies forward benefit and has made larger contribution.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
