Abstract
The utility model relates to a semiautomatic large-scale gear slotting machine, which comprises grip cylinders, a lever, oil cylinders, a fulcrum, a bracket and a slitting disc, wherein the grip cylinders are matched with the fulcrum and the bracket for fixing workpieces, one oil cylinder is connected with the lever, and the other oil cylinder is connected with the slitting disc. Moreover, the slotting machine provided by the utility model further comprises a rigid stop block and a milling cutter, wherein the rigid stop block is combined with the lever for tooth number division, and the milling teeth of the milling cutter mill the cutter slot. The utility model has the benefits of reducing working hours, lowering cost and saving energy consumption.
Description
Technical field
Technical field is a mechanical manufacturing field under the utility model.
Background technology
Development along with China's national defense, engineering machinery, road and bridge engineering, cement industry.The use of big modulus, gear wheel in large diameter more and more widely, quantity is increasing.The task that integrated mill of state-owned enterprise of the existing a few family of China bears is more and more heavier.Finishing this task, to relate to great problem be that equipment investment is high.How to protect equipment, improve this usage ratio of equipment, reducing workpiece holding time on equipment is an important problem.Address the above problem, its key is how as early as possible the blank of teeth groove to be pulled down, gear-hobbing machine is only rolled as essence, and not drawing or lacking the plucking base is unique way.
The ubiquitous headache problem of the gear hobbing of present domestic gear wheel is the blank of taking off fast in the teeth groove.Because it is oversize that it takies time of gear-hobbing machine, over half when will account for the chief engineer man-hour that taking off blank needs, production efficiency is low, quickens the precision forfeiture of main frame.
The method that many families remove blank is: helplessly use ox to dig planing, milling machine milling.The saw blade sawing has appearred using in Xuzhou machinery plant, but there are following five problems in it:
1, the accurate calibration of profile of tooth is rule with model.
2, workpiece is in when cutting and does not clamp shape.
3, the outer circle centering of wheel blank, precision is unreliable.
4, turning of work piece promotes by some people during calibration.
5, after the V-type grooving saw went out, tooth root portion did not have undercut.
How each producer treats plucking base waited in expectation a kind of equipment or method preferably at present, and this patent produces under such background.
The utility model content
In order to solve existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of semi-automatic large gear groover of design, this patent is conceived one by one at five problems that background technology exists, and corresponding each problem is made the scheme of dealing with problems respectively.Its technical scheme is:
A kind of semi-automatic large gear groover, it comprises clamping cylinder, lever, oil cylinder, fulcrum, support, saw disc, and wherein, described clamping cylinder and fulcrum, support cooperate fixation workpiece, and described oil cylinder links to each other with lever, and described another oil cylinder links to each other with saw disc; In addition, groover of the present utility model also comprises rigidity block and milling cutter, and described rigidity block combines number of teeth calibration with lever, described milling cutter mill teeth root undercut.
The beneficial effects of the utility model are: dwindle man-hour, reduce cost, save energy consumption.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is to use the tooth embryo typical part figure of the utility model processing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Be illustrated in figure 1 as the structural representation of present embodiment, the semi-automatic large gear groover of present embodiment, it comprises clamping cylinder 3,4, lever 6, oil cylinder 7,12, fulcrum 8, support 9, milling cutter 10, saw disc 11, described clamping cylinder 3,4 clamps workpiece, four fulcrums 8 and movable endoporus centering support 9 supporting workpieces, rigidity block 5 is used for number of teeth calibration, oil cylinder 7 and lever 6 rotate in conjunction with promoting workpiece, oil cylinder 12 is for sawing machine feeding, and by saw disc 11 processing tooth embryos, milling cutter 10 mill teeth root undercuts.1 is the processed minimum outside diameter of gear of the utility model among Fig. 1; 2 is the processed maximum outside diameter of gear of the utility model.Fig. 2 is to use the tooth embryo typical part figure of the utility model processing.
Domestic prior art background of table 1 and the contrast of the art of this patent scheme are introduced
Table 2 effect analysis
| Processing method | Process time min | Cost (unit) |
| The sawtooth gear hobbing | 2×10×265＝5300 5900 | 15000 24000+10000＝34000 |
| Total time: 11200/ (60 * 24)=7.8 day | Cost amounts to: 49000 | |
| Gear hobbing | 5900 * 4=23600/ (60 * 24)=16.4 day | 93000+40000＝133000 |
Table 2 conclusion:
1, single with gear-hobbing machine processing, the gear hobbing four blade needed finish in 16.4 days altogether.
2, with this patent 2 cuttves, rolling cut 2 cuttves, only needed finish in 7.8 days altogether.As seen the effect of this groover surpasses the effect of the high high precision gear hobber of price.
3, the expense of saving high hobboing cutter.
4, save energy consumption.
Fig. 2 is the tooth embryo typical part figure of the utility model processing, external diameter 8010 * thickness 700.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
