Detailed description of the invention
With reference to accompanying drawing, the utility model cutter for milling machines embodiment is described further.
A kind of cutter for milling machines, comprise knife rest 1, described knife rest 1 is provided with mounting groove 61, milling cutter 2 is connected with in described mounting groove 61, knife rest 1 is provided with holddown groove 11, the tool rest 6 abutted with holddown groove 11 is provided with in holddown groove 11, mounting groove 61 is positioned on tool rest 6, in the process that reality uses, due to the problem of milling cutter 2 machining accuracy, milling cutter 2 can not well and mounting groove 61 suitable (bearing surface of such as milling cutter 2 and fixture 3 can not adaptation completely, or the bearing surface of milling cutter 2 and mounting groove 61 can not adaptation etc. completely), when making to be fixed by fixture 3, milling cutter 2 is stable not, can change tool rest 6 or the mounting groove 61 of tool rest 6 be processed in the above circumstances, make milling cutter 2 can be suitable with mounting groove 61, thus make milling cutter 2 fixation, tool rest 6 is made up of general metal, relative to milling cutter 2 by for high hardness material, the convenience that its processing is got up more, and advantage of lower cost, simultaneously, locking piece 5 is connected with by bolt 4 in holddown groove 11, locking piece 5 side abuts with tool rest 6, opposite side abuts with holddown groove 11 sidewall, also tool rest 6 can be conveniently changed by such mode, improve operating efficiency to a certain extent, also the firm of connection is ensured.Certainly, due to the problem of milling cutter 2 machining accuracy, the distance that each milling cutter 2 on knife rest 1 protrudes mounting groove 61 has a little difference, the absorption surface that the milling cutter 2 comparatively protruded first is processed with needs, milling cutter 2 easily damages, also control by tool rest 6 degree that milling cutter 2 protrudes knife rest 1 end face by above arranging simultaneously, milling cutter 2 is abut with each sidewall of mounting groove 61 when being arranged in mounting groove 61, what to contribute to when milling cutter 2 works comparatively like this is stable, be not easy to rock, milling cutter 2 is regulated to protrude the degree of knife rest 1 end face by regulating the position of tool rest 6 in holddown groove 11 (ensureing that milling cutter 2 abuts with each sidewall of mounting groove 61) simultaneously, ensure that each milling cutter 2 all protrudes at grade, milling cutter 2 is made to be not easy to damage, be conducive to ensureing processing effect and working (machining) efficiency.
Fixture 3 is connected with by bolt 4 in holddown groove 11, fixture 3 side abuts with milling cutter 2, opposite side abuts with holddown groove 11 sidewall, bolt 4 runs through fixture 3 and is threaded with holddown groove 11, when fixing milling cutter 2, milling cutter 2 is first put into mounting groove 61, the cutter head of milling cutter 2 will give prominence to mounting groove 61, fixture 3 is put into afterwards in holddown groove 11, ensure that the both sides of fixture 3 fully abut with milling cutter 2 and holddown groove 11 sidewall respectively, then fixture 3 is fixed with bolt 4, abutting power is so just relied on to fix milling cutter 2, such mounting means, when milling cutter 2 operationally, the power be subject to can be sent on fixture 3, the power be subject to is offset with abutting of holddown groove 11 by fixture 3, share the stressed of bolt 4, the screw thread of bolt 4 is made to be not easy to damage, ensure that the steadiness that milling cutter 2 is fixing, meanwhile, the power that bolt 4 is subject to is radial shearing force, is not easy to damage the screw thread axially arranged, and ensures the reliability that bolt 4 connects.And by above setting, bolt 4 can be fixed without the need to running through milling cutter 2, without the need to carrying out extra processing to milling cutter 2, also can not destroy the structure of milling cutter 2, ensureing the stability of milling cutter 2 structure, make milling cutter 2 milling cutter 2 in the process used be not easy to damage, ensure that its service life.
The two side of holddown groove 11 all tilts to both sides, fixture 3 is suitable with holddown groove 11, certainly, the sidewall of mounting groove 61 also can to tilt lopsidedness to holddown groove 11, with certain gradient when making milling cutter 2 be placed in mounting groove 61 like this, then abutted by face with the fixture 3 of adaptation, milling cutter 2 one power to knife rest 1 center can be given by the bearing surface tilted, milling cutter 2 is made more firmly to be fixed in mounting groove 61, avoid milling cutter 2 operationally can deviate from from mounting groove 61 further, ensure that the stability that milling cutter 2 connects.Locking piece 5 is suitable with holddown groove 11 is to tool rest 6 to knife rest 1 center, avoids tool rest 6 easily to deviate from, ensures the stability that tool rest 6 is fixing.
The length of fixture 3 is greater than the length of mounting groove 61, like this be arranged so that milling cutter 2 can contact fully with fixture 3, can produce when avoiding milling cutter 2 to work and rock, ensure that milling cutter 2 connects stable, the end face of fixture 3 does not protrude from the end face of knife rest 1, is preferably the end face of fixture 3 and the end face of knife rest 1, can better contacts like this with milling cutter 2, time milling cutter 2 fixing more firm, be also not easy milling cutter 2 is damaged.
Locking piece 5 and the place of abutting of tool rest 6 are equipped with anti-skidding lines 7, by such setting, make locking piece 5 and tool rest 6 that relative sliding be less likely to occur, and ensure the stability that tool rest 6 is fixing, add man-hour milling cutter 2 can not indentation inwards, ensure processing effect.
The upper surface of fixture 3 is provided with counter sink; bolt 4 is dormant bolt; by such setting; bolt 4 is made to be not easy to collide with workpiece, cutting object or other object; counter sink plays certain protective effect; thus make bolt 4 that situation about getting loose be less likely to occur, ensure that the stability that fixture 3 connects.The upper surface of fixture 3 is recessed to form arc surface downwards, by such structure, make the stress suffered by fixture 3 can be easy to dispersion, fixture 3 is made to be not easy to damage, meanwhile, avoid fixture 3 can protrude the periphery of knife rest 1, while ensureing the absorption surface that fixture 3 can not be processed with needs, ensure the contact area of fixture 3 and milling cutter 2, ensure fixing comparatively firm of milling cutter 2.Above being arranged on locking piece 5 is applicable equally, and not in this to go forth.
Fixture 3 abuts side with holddown groove 11 and is provided with slot to make way 12, by above setting, when independent fixed disassembly part 3 or locking piece 5, provide rational operating space to the finger of being affectedly bashful, when milling cutter 2 changed by needs, first pull down bolt 4, take out milling cutter 2, be arranged in slot to make way 12 afterwards with the hand-held fixture 3(finger that pinches, another finger can be positioned at mounting groove 61 place) taken out, finger has good impetus, and such mode is by more convenient during fixture 3.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
