Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As Figure 1-5, for a kind of cutter for cylinder holes roughing and chamfering that the present embodiment provides, comprise knife bar 1, the cutterhead 2 be connected with knife bar 1 front end, the handle of a knife 4 be connected with knife bar rear end, described handle of a knife 4 is fixed on boring machine, wherein, described cutterhead 2 is provided with boring cutter, and described boring cutter rear end is fixed with the first rose reamer 3, and the outer edge of described first rose reamer 3 is concordant with described boring cutter outer edge; During in order to make bore hole, the first rose reamer does not affect heavy boring; Wherein, the afterbody of knife bar 1 is fixed with the second rose reamer 6, and in the present embodiment, the first rose reamer 3 is greater than the horizontal range at described cylinder holes two ends apart from the horizontal range of described second rose reamer 6.Object, when import chamfer machining is completed, exits cylinder holes, now drives the first rose reamer to move up and down the processing that can realize exit chamfering by boring machine.
Particularly, in the present embodiment, the afterbody of cylinder holes offers a groove, in groove, have a L-type fixed block 5 along knife bar 1 axial restraint; Wherein the base of L-type fixed block 5 is fixed on described knife bar 1, and the one end on L-type fixed block 5 base contacts with recess sidewall; The protruding described groove of L-type fixed block 5 top margin, the second rose reamer 6 is arranged on the top margin side of L-type fixed block.Namely the second rose reamer 6 is arranged on guide rod by L-type fixed block 5, adopts L-type fixed block 5 to be not only convenient to the installation of the second rose reamer, and by L-type fixed block base and groove front end or afterwards end in contact also play the effect of locating and regulating.
Preferably, in this programme, in order to easy for installation, the base of L-type fixed block contacts with the inside side walls of groove; In order to avoid the base of L-type fixed block produces obstruction to heavy boring process, in this programme, the base thickness of L-type fixed block is less than or equal to the degree of depth of groove.It should be noted that, inside side walls is the sidewall away from boring machine.
Firm in order to make fixed L type fixed block 5 install, the present embodiment is simultaneously to the level of L-type fixed block and vertically carry out fastening; Wherein, offer screw in the horizontal direction in the one end away from groove inside side walls on base, adopt an axial adjustment bolt 7, wherein, one end of axial adjustment bolt 7 contacts with the outside side wall of described groove, and the other end coordinates with described screw.The fastening of L-type fixed block horizontal direction is achieved by axial adjustment spiral shell 7 bolt; Further, base also offers a vertical threaded bore, described L-type fixed block is fixed on described knife bar by set bolt 9, adopts set bolt 9 to achieve the fastening of vertical direction.
In the present embodiment, for the ease of the collection to refuse, in the front end of guide rod, chip area 8 is also installed.
As shown in Figure 4, Figure 5, during work, first, cutter 11 front end enters the cylinder holes of cylinder body 10, completes the heavy boring to cylinder holes, and wherein, the scrap produced in heavy boring process is collected by the chip area being arranged on guide rod front end; Then, the second rose reamer being arranged on knife bar afterbody carries out chamfer machining to the porch of cylinder holes, and now because the distance of two rose reamers is greater than the horizontal range of cylinder holes, the first rose reamer stretches out cylinder holes.Secondly, translation cutter backward, now, the first rose reamer, the second rose reamer all outside cylinder holes, by boring machine up-down adjustment tool position; Finally, horizontal translation cutter, makes the first rose reamer contact with the exit of cylinder holes, starts export processing chamfering.
In sum, the present embodiment, by adopting two rose reamers be arranged on before and after knife bar, can realize the processing that employing cutter can realize cylinder holes import chamfering and outlet chamfering, improve operating efficiency during cylinder holes chamfer machining, reduce processing cost.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
