Description
Technical field
The utility model relates to boring machine field of mechanical technique, refers in particular to a kind of milled head of deep hole boring machine.
Background technology
At present, the deep-hole tight-face blasting technique of the column of coal-mine hydraulic support or the earthen pipe of jack generally adopts the technique of right boring+roll extrusion Compound Machining or the combination process of scraping+roll extrusion.In above two kinds of schemes, the bore area quality of the first is analyzed from microcosmic, if the amount of feeding when right boring is excessive, crest can be caused to strike the beam, and occurs the phenomenon of peeling after using half a year to year; The second process program, bore area quality is no problem, and shortcoming is that scraping tumbling special purpose machine tool involves great expense, and is roughly equal to RMB more than 1,000 ten thousand yuan.Boring cutter is the one of cutting tool for boring, generally there is one or two cutting tip to be specifically designed to and carry out roughing, semifinishing or accurately machined cutter to porose, at present, the phenomenon that cutter breaks easily is there is in known two cuttves in the process of boring, not only have impact on the machining accuracy of workpiece, and its security performance can not be ensured.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the milled head that a kind of structure of deep hole boring machine is simple, result of use is good.
For achieving the above object, technical scheme provided by the utility model is: a kind of milled head of deep hole boring machine, the guide ring that it includes central shaft and is set with successively on center shaft, plane bearing, adjustable ring, retainer ring, roll extrusion ring, described guide ring suit on center shaft, its outer peripheral face is evenly equipped with some locating pieces, plane bearing suit on center shaft, its one end and guide ring are conflicted, the other end and adjustable ring are conflicted, adjustable ring ring body is provided with suit notch, the central shaft of adjustable ring opposite side is set with successively retainer ring and roll extrusion ring, wherein, roll extrusion ring outer peripheral face is evenly equipped with some rolling grooves, in each rolling groove, all activity is equipped with a hole wall pressure roller, the rolling surface of the hole wall pressure roller after assembling protrudes from roll extrusion ring surface, the central shaft end of roll extrusion ring side is provided with boring cutter seat, and car boring cutter one end is by bolt-locking in boring cutter seat, and boring cutter seat extends to form bore hole cutting edge to roll extrusion ring outer peripheral face direction.
The utility model is after employing such scheme, and car boring cutter adopts combined type by bolt-locking, and boring cutter is damaged rear replaceable, without the need to changing together with boring seat, can greatly reduce enterprise's production cost; After adopting rolling groove and hole wall pressure roller, roll extrusion fine finishining can be carried out to hole inwall while bore hole, make the smooth consolidation of hole inner wall surface; When locating piece can prevent bore hole, central shaft vibrates when boring cutter; Increase Boring preciseness.The structure of this programme is simple, result of use good, bore hole rear surface is smooth, meticulous.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, most preferred embodiment of the present utility model is: see accompanying drawing 1, the milled head of a kind of deep hole boring machine described in the utility model includes central shaft and is set with guide ring 1 on center shaft successively, plane bearing 2, adjustable ring 3, retainer ring 7, roll extrusion ring 4, described guide ring 1 is set with on center shaft, its outer peripheral face is evenly equipped with some locating pieces 5, plane bearing 2 is set with on center shaft, its one end and guide ring 1 are conflicted, the other end and adjustable ring 3 are conflicted, adjustable ring 3 ring body is provided with suit notch 6, the central shaft of adjustable ring 3 opposite side is set with successively retainer ring 7 and roll extrusion ring 4, wherein, roll extrusion ring 4 outer peripheral face is evenly equipped with some rolling grooves 8, in each rolling groove 8, all activity is equipped with a hole wall pressure roller 9, the rolling surface of the hole wall pressure roller 9 after assembling protrudes from roll extrusion ring 4 surface, the central shaft end of roll extrusion ring 4 side is provided with boring cutter seat 10, and car boring cutter 11 one end is by bolt-locking in boring cutter seat 10, and boring cutter seat 10 extends to form bore hole cutting edge to roll extrusion ring 4 outer peripheral face direction.This device is after employing such scheme, and car boring cutter adopts combined type by bolt-locking, and boring cutter is damaged rear replaceable, without the need to changing together with boring seat, can greatly reduce enterprise's production cost; After adopting rolling groove and hole wall pressure roller, roll extrusion fine finishining can be carried out to hole inwall while bore hole, make the smooth consolidation of hole inner wall surface; When locating piece can prevent bore hole, central shaft vibrates when boring cutter; Increase Boring preciseness.The structure of this programme is simple, result of use good, bore hole rear surface is smooth, meticulous.
The embodiment of the above is only the most preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, be all encompassed in protection domain of the present utility model.
