For achieving the above object, technical scheme provided by the utility model is: a kind of cutter structure on milling machine, comprise housing, also include the travelling gear being arranged at the mill cutter assemblies on described housing bottom, the pressing plate in described housing sidewall, the gear pressure plate driven by the drive of this pressing plate, tooth bar pressing plate and being arranged between described gear pressure plate and tooth bar pressing plate, described mill cutter assemblies comprises the first milling cutter group that ecto-entad is arranged successively, second milling cutter group and the 3rd milling cutter group, wherein said first milling cutter group is fixedly connected on described housing bottom, described second milling cutter group and the 3rd milling cutter group form being slidably connected of vertical direction with described housing respectively and are correspondingly arranged at below described tooth bar pressing plate and gear pressure plate, when described tooth bar pressing plate and gear pressure plate press down, it drives described second milling cutter group and the 3rd milling cutter group to move down to carry out tool changing separately respectively, simultaneously described second milling cutter group and the 3rd milling cutter group are also provided with separately and carry out for it the back-moving spring that resets.
Further, described 3rd milling cutter group it comprise handle of a knife, knife rest and be installed on multiple circumferentially directions on this knife rest blade spaced apart, described knife rest includes fixed mounting and cutter holding portion, wherein its outward flange of this fixed mounting is provided with profile of tooth block, the front end of this profile of tooth block is provided with indent, and the two sides of this indent is provided with the locking screw pit for installing described blade.
Again further, described gear pressure plate and tooth bar pressing plate are linked into an integrated entity by connecting plate, and the outside of wherein said gear pressure plate is also provided with limited block.
This programme is by adopting housing, be arranged at the mill cutter assemblies on above-mentioned housing bottom, be positioned at the pressing plate in above-mentioned housing sidewall, the gear pressure plate driven is driven by this pressing plate, tooth bar pressing plate and be arranged at the version of the travelling gear between said gear pressing plate and tooth bar pressing plate, can make during work, first to utilize the first milling cutter group to process, when needs carry out tool changing, gear pressure plate is promoted by lower platen, so that limited block blocks gear pressure plate while of making gear pressure plate be meshed with gear, motor action and then driven gear pressing plate move down, and then promote the 3rd milling cutter group and move down and reach the Working position of specifying and carry out machining, whole milling cutter exchanging knives process is simple and convenient in above process, do not need to unload cutter, save process time greatly, effectively raise enterprises production efficiency.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail:
Shown in accompanying drawing 1, a kind of cutter structure on milling machine described in the present embodiment, comprise housing 1, switch 13, be arranged at the mill cutter assemblies 11 on above-mentioned housing 1 bottom, the pressing plate 2 on housing 1 sidewall, the travelling gear 12 that driven the gear pressure plate 15 of driving, tooth bar pressing plate 7 by this pressing plate 2 and be arranged between said gear pressing plate 15 and tooth bar pressing plate 7, said gear pressing plate 15 and tooth bar pressing plate 7 are linked into an integrated entity by connecting plate 16, and wherein the outside of gear pressure plate 15 is also provided with limited block 3, above-mentioned mill cutter assemblies 11 comprises the first milling cutter group 9 that ecto-entad is arranged successively, second milling cutter group 10 closes the 3rd milling cutter group 8, wherein above-mentioned first milling cutter group 9 is fixedly connected on housing 1 bottom, second milling cutter group 10 and the 3rd milling cutter group 8 form being slidably connected of vertical direction with above-mentioned housing 1 respectively and are correspondingly arranged on below above-mentioned tooth bar pressing plate 7 and gear pressure plate 15, when tooth bar pressing plate 7 and gear pressure plate 15 press down, it drives the second milling cutter group 10 and the 3rd milling cutter group 8 to move down to carry out tool changing processing operation separately respectively, concrete is when gear pressure plate 15 and tooth bar pressing plate 7 are carrying out in the course of action moved down, it promotes the second milling cutter group 10 and the 3rd milling cutter group 8 respectively by the first slurcam 6 and the second slurcam 5 that are arranged on its lower end separately and moves down and carry out tool changing processing operation, simultaneously above-mentioned second milling cutter group 10 and the 3rd milling cutter group 8 are also provided with separately and carry out for it the back-moving spring 14 that resets.
In addition, combine with reference to shown in accompanying drawing 2 again, in order to change the low problem of its utilization rate of traditional cutter for milling machines, above-mentioned 3rd milling cutter group 8 in this programme it comprise handle of a knife 801, the blade 803 that knife rest 802 is spaced apart with the multiple circumferentially directions be installed on this knife rest 802, above-mentioned knife rest 802 includes fixed mounting and cutter holding portion, wherein its outward flange of this fixed mounting is provided with profile of tooth block 806, the front end of this profile of tooth block 806 is provided with indent 807, the two sides of this indent 807 is provided with the locking screw pit 805 for installing blade 803, when blade 803 is installed, they can by the needs of actual work in-process, by lock screw 804, blade 803 is arranged in the locking screw pit 805 of the profile of tooth block 806 on diverse location.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
