And two kinds of speed also need to be regulated the speed according to the situation of workpieces processing, and transmission bar can use leading screw or feed rod, and power
Transmission often has following form：
1st, using two motors, feed is respectively used to quickly, passes through traditional gear transmission mode respectively（It is equivalent to one
Platform gear-box）, power is transferred to transmission bar；And the speed ratio of two driving-chains is different, so that feed and quick speed
It is different；In driving-chain, change gear can also be increased and carry out adjusting speed ratio, while frequency converter can also be increased on cutting feed, led to
The supply frequency of frequency converter is overregulated, so as to reach adjusting feeding speed；
2nd, using servomotor, by way of numerical control, with the direct-connected transmission bar of a servomotor or in servomotor
Increase level-one precision speed reduction device between transmission bar.The characteristics of using servomotor perseverance torque, motor can be caused at specified turn
Fast following, free regulation motor speed, while do not reduce motor output torque can so realize feed and two kinds quick simultaneously
Speed, and feeding speed is adjustable；
More than first way, the structure of mechanical part is sufficiently complex, and the accuracy of manufacture of gear-box is more demanding；And the
Although two kinds of modes can be very good to solve the problems, such as, and have the characteristics that digital control scheme precision is high, the complexity of mechanical system is low,
But the purchase of digital control system is of a high price, and for long-time service, if servomotor or digital control system break down, after
The operation and maintenance cost of phase is also higher.For a big chunk lathe, and need not be very high precision, cost is just at this time
Into a key factor.
The content of the invention
In order to solve the problems, such as present in background technology, the purpose of this utility model is to propose a kind of heavy machine tool with compound
Transmission mechanism, the composite driving mechanism can realize two kinds of transmission speeds, to meet the respective demand of transmission and feed, have simultaneously
The characteristics of being simple to manufacture, be of low cost, is easy to use, later maintenance cost is low.
To achieve the above object of the invention, the utility model adopts the following technical solution：
A kind of heavy machine tool composite driving mechanism, including alternating current generator I, retarder I, alternating current generator II, retarder II,
Electromagnetic clutch and connecting shaft, the output shaft of alternating current generator II are connected with the input terminal of retarder II, the output terminal of retarder II
By connecting one end of axis connection electromagnetic clutch, the other end of electromagnetic clutch is exported by connecting flange and alternating current generator I
One end connection of axis, the other end of alternating current generator I output shafts are connected with retarder I.
Preferably, the retarder I is in vertical installation, and retarder II is in horizontal installation.
Preferably, the retarder I and retarder II is cycloidal-pin gear speed reducer.
Preferably, alternating current generator I and alternating current generator II are connected to frequency converter.
Preferably, the hold-down support being used to support with retarder II is set in the lower part of retarder II.
Due to the adoption of the above technical scheme, the utility model has following superiority：
The utility model can not only realize two kinds of transmission speeds of transmission and feed simultaneously, and speed can be in certain model
Enclose it is interior adjustable, and have the characteristics that be simple to manufacture, of low cost, easy to use, later maintenance cost is low.

Specific embodiment
The technical solution of the utility model is further described in detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of heavy machine tool composite driving mechanism, including alternating current generator I, retarder I, alternating current generator
II, retarder II, electromagnetic clutch and connecting shaft, the output shaft of alternating current generator II are connected with the input terminal of retarder II, are slowed down
The output terminal of device II passes through connecting flange with handing over by connecting one end of axis connection electromagnetic clutch, the other end of electromagnetic clutch
One end connection of galvanic electricity machine I output shafts, the other end of alternating current generator I output shafts are connected with retarder I.
The retarder I and retarder II is cycloidal-pin gear speed reducer.
Alternating current generator I and alternating current generator II are connected to frequency converter.
Since the entire length of the utility model is longer, in order to ensure whole stability, under retarder II
Portion sets the hold-down support being used to support with retarder II.
The utility model is suitable for quick rotation and two kinds of speed requirements of feed that lathe needs, i.e.,：Pass through alternating current generator I
And retarder I realizes the quick rotation for the transmission bar being connected with retarder I output terminals；Pass through alternating current generator II, retarder
II, electromagnetic clutch and alternating current generator I, retarder I realize the control of feeding speed.
As the preferred of the utility model, the alternating current generator I and alternating current generator II are connected to frequency converter, when
So, the utility model in specific application, has further included electric control system, by setting frequency converter, can make feeding speed
Step-less adjustment is carried out with atwirl speed, stepless speed regulation is carried out to meet to be actually needed.
The operation principle of the utility model is：According to operation needs, if quick rotation status is adjusted to, by electrical
Control system separates electromagnetic clutch 4, and control alternating current generator I 2 operates, and after the deceleration of retarder I 1, drives transmission
Thick stick quickly rotates, and the rotary speed of transmission bar can be by adjusting with the mating frequency converter of alternating current generator I 2；If it is adjusted to feed
State is then attracted electromagnetic clutch 4 by electric control system, and alternating current generator II 7 rotates at this time, by retarder II and subtracts
The double reduction of fast device I drives transmission bar rotation, at this time can also be by matching somebody with somebody with alternating current generator II 7 so as to fulfill feed function
The frequency converter of set adjusts rotary speed.
The composite driving mechanism of the utility model in a pre-installation, common quick rotary speed first according to actual needs and
Feeding speed determines the rated speed of alternating current generator I and alternating current generator II, and the fast ratio of definite two retarders, such as：It needs
The overall ratio of quick rotation is A, and the overall ratio of feed is B, then actual in retarder selection, selected retarder
I 1 fast ratio is A, and the fast ratio for the retarder II 6 that feed uses is B/A；When installing electromagnetic clutch, it is necessary to by alternating current generator I
The cooling fans of 2 tail ends is removed, and manufacture connecting flange 3 is surveyed and according to subtracting according to the size of I 2 afterbody main shaft of alternating current generator
The output shaft diameter and length of fast device II 6, actual measurement manufacture connecting shaft 5.
Alternating current generator I selects the common alternating current generator of 11kw, and alternating current generator II is selected the common alternating current generator of 1.5kw, subtracted
Fast device I selects model Jiangsu ACE Semi retarder X7-17-11, the model Jiangsu ACE Semi retarder X63- that retarder II is selected
