Abstract
The utility model discloses a transmission system of a spindle box of a milling and boring machine, which comprises a boring shaft, a motor and a spindle box body. A rotor of the motor is supported on the spindle box body through a bearing, a stator of the motor is fixedly mounted on the spindle box body, and the boring shaft is mounted in the rotor of the motor and can move axially. The transmission system of the spindle box of the milling and boring machine is simple in structure and higher in transmission efficiency and rotation speed.
Description
Technical field
The utility model belongs to the Metal Cutting Machine Tool field, especially relates to a kind of milling-boring machine main spindle box transmission system.
Background technology
Along with the high speed development of China's machinery manufacturing industry, increasing to the demand of various milling-boring machines, existing milling-boring machine main spindle box transmission system needs mechanical reduction and mechanical speed change, complex structure, and precision, efficient and rotating speed are all on the low side.
Summary of the invention
The purpose of the utility model is: a kind of simple for structure, transmission efficiency and the high milling-boring machine main spindle box transmission system of rotating speed are provided.
The technical scheme of the utility model is: milling-boring machine main spindle box transmission system comprises boring axle, motor, main shaft casing; Motor comprises rotor, motor stator and motor housing; Rotor passes through bearings on the main shaft casing; Motor stator is fixedly mounted on the main shaft casing, and the boring axle is installed in the rotor and can moves vertically.
The end of said rotor can the installed with milling cutter dish.
Said rotor connects the drive encoder through synchronous belt transmission device.
The beneficial effect of the utility model is: since milling-boring machine main spindle box transmission adopted motor stator be fixed on the main shaft casing; The boring axle is installed in the rotor; Make milling-boring machine main spindle box transmission system form motor and directly drive the boring axle, the end of rotor can the installed with milling cutter dish, with installed with milling cutter; Make the structure of milling-boring machine main spindle box transmission system more succinct, precision, transmission efficiency and rotating speed are higher.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is A-A cutaway view of Fig. 1.
Mark explanation among the figure: 1, boring axle, 2, screw, 3, end cap, 4, fore bearing, 5, rotor; 6, motor stator, 7, motor housing, 8, encoder, 9, be with small pulley synchronously, 10, band synchronously; 11, main shaft casing, 12, the fore bearing locking nut, 13, rear bearing, 14, the rear bearing locking nut; 15, broaching tool dish spring, 16, be with big belt wheel synchronously, 17, back-up ring, 18, feather key.
The specific embodiment
Can find out that from the structural representation of the utility model shown in Figure 1 and the A of Fig. 2-A cutaway view the utility model mainly contains: main shaft casing 11, boring axle 1, motor, end cap 3, oil sealing, fore bearing 4, fore bearing locking nut 12, rear bearing 13, rear bearing locking nut 14, synchronously be with big belt wheel 16, be with 10 synchronously, be with compositions such as small pulley 9, encoder 8, broaching tool dish spring 15, end cap 3, back-up ring 17, screw 2, oil sealing synchronously.Motor comprises rotor 5, motor stator 6 and motor housing 7, and employing can realize the adjustable speed motor of permanent torque, the output of permanent power.Rotor 5 is supported on the main shaft casing 11 through front and back bearings; Motor stator 6 is fixedly mounted on the main shaft casing 11; Boring axle 1 is directly installed in the rotor 5, and rotor 5 drives 1 rotation of boring axle through feather key 18, and boring axle 1 also can move axially in rotor 5.The afterbody of boring axle 1 is equipped with broaching tool dish spring 15.The end of rotor 5 can the installed with milling cutter dish, with installed with milling cutter.Encoder 8 and synchronous band small pulley 9 are housed on the motor housing 7, the big belt wheel 16 of synchronous band is housed on the rotor 5, drive encoders 8 rotations through being with 10 synchronously, encoder 8 sends signal and passes to the control system, for use in regulating the control of rotating speed and multiaxis couplet.
The utility model is compared with traditional milling-boring machine main spindle box transmission system, has removed milling spindle, and rotor is directly driven the boring axle, and can be in the end of rotor can installed with milling cutter dish and milling cutter, make transmission efficiency and rotating speed higher.
