Description
Technical field
The utility model relates to a kind of industrial lathe, refers to a kind of superduty floor-type milling & boring machine especially.
Background technology
Present floor-type milling & boring machine almost all adopts the central driving form to realize, machine tool structure is very complicated, the outmoded relatively backwardness of structure.The all feed motions of lathe drag by an alternating current generator; Switch through planetary differential gear mechanism and 14 group electromagnetic clutch, obtain the feed motion of different directions, but because the driving-chain of all directions feed shaft is long, number of parts is many; The backlass that brings is excessive; Add the electromagnetic clutch response lag, therefore when diaxon interpolation feeding, asynchrony phenomenon occurs, very easily produce stepped mismachining tolerance.
For making this equipment can adapt to the modern production requirement, give full play to its mechanical dominance, so must go to the numerical control transformation plan thing of this equipment.
The utility model content
The purpose of the utility model is to overcome the defective of prior art, and a kind of novel floor-type milling & boring machine is provided, and realizes reducing the complexity and the maintenance difficulty of control, practices thrift cost.
The technical scheme that realizes above-mentioned purpose is:
A kind of floor-type milling & boring machine of the utility model comprises: one first driving-chain is used to drive the feeding of saddle slide; One second driving-chain is used to drive the feeding of boring case; And one the 3rd driving-chain, be used for driving simultaneously feeding of boring axle and ram feeding.
Said first driving-chain that further is of the utility model comprises servomotor, the planetary reduction gear that is in transmission connection successively, shaft coupling, transmission bar, coupling spindle and worm screw.
Said second driving-chain that further is of the utility model comprises driven by servomotor, planetary reduction gear and the ball-screw that is in transmission connection successively.
Said the 3rd driving-chain that further is of the utility model comprises servomotor, planetary reduction gear, shaft coupling, power transmission shaft and the conical gear that is in transmission connection successively.
The floor-type milling & boring machine of the utility model improves transmission accuracy and transmission stiffness through the mode of decomposition and shortening driving-chain, reduces the usage quantity of driving parts electromagnetic clutch to greatest extent, to reduce the complexity and the maintenance difficulty of control.

The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
The floor-type milling & boring machine of the utility model with original by a motor-driven; The kind of drive through planetary cross-country power mechanism and electromagnetic clutch switch is rationally decomposed; Comprise that one is used to drive first driving-chain of saddle slide feeding, second driving-chain and that is used to drive the feeding of boring case is used for driving simultaneously the 3rd driving-chain of feeding of boring axle and ram feeding.
Consult Fig. 1, shown in 2, its operation principle is:
First driving-chain through planetary reduction gear 2 reductions of speed, connects transmission bar 4, coupling spindle 5 by shaft coupling 3 by servomotor 1, drags slide and realizes through worm screw 6, worm gear 7 switching-overs again;
Second driving-chain, by servomotor 29 drivings, planetary reduction gear 28 reductions of speed, Y axle ball-screw 22 drives the boring casees and realizes;
The 3rd driving-chain, is connected power transmission shaft 13, is driven conical gear 16,18 switching-over transmissions by shaft coupling 12 through planetary reduction gear 11 reductions of speed by Z, W axle servomotor 10, in being uploaded to the boring and milling main spindle box, drags realization respectively by Z, W transmission bar 21 again.
Through structural significant improvement,, improved the feeding transmission accuracy of lathe effectively and improved transmission rigidity guaranteeing to utilize original each hole of casing that feeding driving-chain maximum degree of holding is shortened under the constant situation of original drive path.
