Abstract
The invention discloses a transmission system of a spindle box of a milling and boring machine. The transmission system comprises a boring shaft, a motor and a spindle box body, wherein the motor comprises a motor rotor, a motor stator and a motor shell; the motor rotor is fixedly arranged on a hollow shaft; the motor stator is fixedly arranged on the spindle box body; the hollow shaft is supported in the spindle box body through a bearing; and the boring shaft is arranged in the hollow shaft. The transmission system has a simple structure and higher precision, transmission efficiency and rotating 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 is fixedly mounted on the hollow shaft, motor stator is fixedly mounted on the main shaft casing, in the main shaft casing, the boring axle is installed in the hollow shaft hollow shaft by bearings.
Facing cutter can be installed in the end of described hollow shaft.
Described rotor connects the drive encoder by synchronous belt transmission device.
The invention has the beneficial effects as follows: since milling-boring machine main spindle box transmission adopted rotor directly be fixedly mounted on the hollow shaft, motor stator directly is fixed on the main shaft casing, hollow shaft is supported between the interior front and back bearings of main shaft casing, the boring axle is installed in the hollow shaft, make milling-boring machine main spindle box transmission system form the direct drive sleeve of motor, boring axle, thereby making the structure of milling-boring machine main spindle box transmission system more succinct, precision, transmission efficiency and rotating speed are higher.
