It can also be according to the customized extraordinary junk mill of customer demand.
Existing junk mill can cooperate drilling well to use, but in actual use, the external big orifice alloy column of junk mill is general
It is all fixed dimension, when cooperating built in soft segment column and alloy-layer, flexibility is lower, can not be used cooperatively, and needs to add a variety of
The big orifice alloy column of specification, capital investment is high, and transfer difficulty is big, these are all physical presence and urgent problem.
Summary of the invention
The purpose of the present invention is to provide a kind of big orifice junk mill devices, to solve junk mill mentioned above in the background art
External big orifice alloy column be typically all fixed dimension, when cooperating built in soft segment column and alloy-layer, flexibility is lower, can not
It is used cooperatively, needs to add the big orifice alloy column of plurality of specifications, capital investment is high, the big problem of transfer difficulty.
To achieve the above object, the invention provides the following technical scheme: a kind of big orifice junk mill device, including big orifice close
Principal column, buffer, link block, main internal frame, secondary internal frame, soft segment column, stern post, annular groove, alloy-layer and chip space, the big orifice close
The circumferential inner wall of principal column is welded with buffer, and the buffer left and right sidewall, which is bolted, is equipped with link block, the master
The left and right sidewall of internal frame and secondary internal frame with connect block welding, the soft segment column and stern post integrated molding, outside the circumference of the stern post
Wall offers annular groove, is bolted at the top of the soft segment column and is equipped with alloy-layer, offers at the top of the alloy-layer
Chip space.
Preferably, the top of the alloy-layer is integrally formed and is connected with twill.
Preferably, the left and right sidewall bottom of the main internal frame and secondary internal frame offers slope.
Preferably, the inner cavity of the buffer includes buffer spring.
Preferably, the material of the main internal frame and secondary internal frame is stainless steel plate.
Compared with prior art, buffer is installed in inner cavity, convenient for the contraction and rebound of main internal frame and secondary internal frame, dimensional fits
Degree is high, and secondly the slope of the main internal frame of cooperation and secondary internal frame bottom, plays guiding function, facilitate built in soft segment column, strong flexibility,
Buffer spring is built in inside buffer, in chip space in use, will not make by scrap Caton inside buffer spring, ensure that makes
Smoothness.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is schematic internal view of the present invention；
Fig. 3 is alloy column schematic diagram of the present invention.
In figure: 1- big orifice alloy column, 2- buffer, 3- link block, the main internal frame of 4-, 5- pair internal frame, 6- soft segment column, 7- tail
Column, 8- annular groove, 9- alloy-layer, 10- chip space, 11- twill.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the invention provides the following technical scheme: a kind of big orifice junk mill device, including big orifice alloy
Column 1, buffer 2, link block 3, main internal frame 4, secondary internal frame 5, soft segment column 6, stern post 7, annular groove 8, alloy-layer 9 and chip space 10, institute
The circumferential inner wall for stating big orifice alloy column 1 is welded with buffer 2, and 2 left and right sidewall of buffer, which is bolted, to be equipped with
Link block 3, the left and right sidewall and link block 3 of the main internal frame 4 and secondary internal frame 5 are welded, the soft segment column 6 and 7 one of stern post at
Type, the outer circumferential walls of the stern post 7 offer annular groove 8, and the top of the soft segment column 6, which is bolted, is equipped with alloy-layer 9,
The top of the alloy-layer 9 offers chip space 10.
The top of the alloy-layer 9 is integrally formed and is connected with twill 11, and the setting of twill 11 increases the wear-resisting of alloy-layer 9
Property, increase resistance.
The left and right sidewall bottom of the main internal frame 4 and secondary internal frame 5 offers slope, such setting convenient for alloy-layer 9 with
Main internal frame 4 and the effectively connection of secondary internal frame 5.
