Abstract
The invention discloses a transmission system for a spindle box of a boring and milling machine. The transmission system comprises a boring shaft, a motor and a spindle box body; a motor rotor is supported on the spindle box body through a bearing; a motor stator is fixedly installed on the spindle box body; and the boring shaft is installed in the motor rotor and can move along an axial direction. The transmission system is simple in structure and high in transmission efficiency and rotational speed.
Description
Technical field
The invention belongs to the Metal Cutting Machine Tool field, especially relate 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 objective of the invention 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.
Technical scheme of the present invention 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 invention has the beneficial effects as follows: 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 a structural representation of the present invention;
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, synchronous band, 11, the 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 A-A cutaway view of structural representation of the present invention shown in Figure 1 and Fig. 2 the present invention 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 present invention compares 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.
