Abstract
The utility model discloses a main shaft transmission device of a milling and boring machine, which comprises a main shaft box body, a main shaft servomotor, a gear case and a square ram, wherein the main shaft servomotor and the gear case are arranged on the square ram; a planetary gear reducer is driven by an output shaft of the main shaft servomotor; a gear in the gear case is driven by the output shaft of the planetary gear reducer; and the gear on a milling shaft is driven by the gear in the gear case. The transmission device is simplified, the work noise is reduced and the transmission precision and the transmission stability are improved.
Description
Technical field:
The utility model belongs to the Metal Cutting Machine Tool field, especially a kind of spindle gearing with square ram type milling-boring machine.
Background technology:
In band side's ram type main axis transmission system of tradition milling-boring machine, spindle drive motor is installed on the main shaft casing, simultaneously uni-drive gear box is set in main spindle box, many rooted teeth wheel shaft is arranged, overpay travelling gear and be transferred on the gear in the gear bag, again by the gear drive in the gear bag to milling spindle.On the gear bag side of the being installed in ram, need do moving of big distance with the flexible of square ram, so the gear in the gear bag, need drive with the elongated splined shaft of output shaft output in the main shaft casing.Complex structure, make difficulty, big, the maintenance difficult of operating noise, be not easy to further improve the precision and the stability of spindle operation.
Summary of the invention:
The purpose of this utility model is: at the technical problem of above-mentioned existence, provide a kind of spindle gearing of simple in structure, transmission accuracy is high, transmission stability is good milling-boring machine.
The technical solution of the utility model is: comprise main shaft casing, main axle servo motor, gear bag, square ram, in side's ram milling spindle and boring axle are set, on main axle servo motor, the gear bag side of the being installed in ram, side's ram moves in the main shaft casing and along the main shaft casing, pinion and idler gear are housed in the gear bag, the output shaft of main axle servo motor is by the pinion in the planetary reducer connection gear bag, pinion is installed in gear wheel on the milling spindle by intermediate gear drives, and planetary reducer is by on the reducer stent side of the being installed in ram; Milling spindle in square ram inside, is equipped with feather key between milling spindle and the boring axle by roller bearings, and the boring axle is flexible in milling spindle.
The beneficial effects of the utility model are: owing to cancelled interior mechanical reduction gearbox and the elongated splined shaft of main spindle box, using advanced main axle servo motor, planetary reducer instead replaces, main axle servo motor, gear bag and planetary reducer all are installed on the ram, the output shaft of main axle servo motor drives planetary reducer, gear in the output shaft driven wheel bag of planetary reducer, gear on the gear drive milling spindle in the gear bag, simplified transmission device, reduce operating noise, improved transmission accuracy and transmission stability.
Description of drawings:
Fig. 1 is the front view of the spindle gearing of a kind of milling-boring machine of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The specific embodiment:
From the left view of the vertical view of the front view of the spindle gearing of a kind of milling-boring machine of the utility model shown in Figure 1 and Fig. 2, Fig. 3 as can be seen, the utility model mainly is made up of main shaft casing 12, square ram 11, main axle servo motor 8, planetary reducer 6, reducer stent 7, gear bag 4, milling spindle 2, boring axle 1, feather key 14 etc.
Side's ram 11 adopts existing linear motion guide, is supported in the main shaft casing 12.Main axle servo motor 8, gear bag 4 and planetary reducer support 7 side's of being installed in rams 11 tops, on main axle servo motor 8 and gear bag 4 side's of the being directly installed on rams 11, planetary reducer 6 is installed on the reducer stent 7, on reducer stent 7 side's of being installed in rams 11.Main axle servo motor 8 adopts AC servomotor, and the output shaft of AC servomotor is connected with the input of planetary reducer 6.With rolling bearing pinion 5 and idler gear 3 are installed in the gear bag 4, pinion 5 in the output shaft driven wheel bag 4 of planetary reducer 6, pinion 5 in the gear bag drives milling spindle 2 runnings by the gear wheel 13 of idler gear 4 drive installations on milling spindle 2.
It can also be seen that from the front view of Fig. 1 milling spindle 2 with the accurate main shaft roller bearings in the square ram 11, milling spindle 2 is hollow, be equipped with respectively through hardening and precision machined slip cap, in order to the boring axle 1 of stayed surface nitrogen treatment the front and rear part of endoporus.Main axle servo motor 8 drives milling spindle 2 runnings by the gear wheel 13 of two gears in planetary reducer 6, the gear bag 4 and milling spindle 2 afterbodys.Two feather keys 14 of symmetry are housed between milling spindle 2 and the boring axle 1 simultaneously,, make boring axle 1 on, can also in milling spindle 2, stretch with milling spindle 2 synchronous operated bases by boring axle 1 surperficial corresponding two featherways.
Ram feed arrangement 9 and boring axle feed arrangement 10 are equipped with in the end of side's ram 11, move along main shaft casing 12 by ram feed arrangement 9 drive side's rams 11, and it is flexible in milling spindle 2 to drive boring axle 1 by boring axle feed arrangement 10.
