Problems solved by technology
[0003] The hub processing lathe is a special-purpose machine tool. The larger-diameter hub, plus clamping fixtures, transmission pulleys and other components are all installed on the main shaft, which need to be driven by the main shaft motor to rotate. The increase in the speed of the main shaft is limited, and it is easy to produce main shaft. Vibration (also mentioned in the patent CN203030894U), it is difficult to achieve a bright finish on the surface of the wheel hub after turning, and the wheel hub with high surface requirements has to be polished after turning.
Low polishing efficiency, poor environment, and high labor intensity

Embodiment Construction
[0017] refer to figure 1 and figure 2 The base 1 is under the electric spindle lathe for turning the bright surface of the wheel hub, and the bed 2 inclined at 45° is fastened on the base. This arrangement can make the machine tool have good rigidity, and the spindle box is fixed below the left end of the bed 2 3. The spindle box is fixed, and the spindle box is equipped with an electric spindle, which eliminates the spindle drive pulley, reduces the rotational load of the spindle, and makes the spindle have the characteristics of high rotation accuracy, high speed, good rigidity, and small vibration. The spindle speed can also be adjusted. It has been greatly improved, not only improving the quality of surface processing, but also significantly improving production efficiency.
[0018] What has been described above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle and co...

An electric spindle lathe for hub polished surface turning comprises a base, a lathe bed and a spindle box, wherein the spindle box is located on a horizontal lathe body at the end of the lathe bed, and a spindle installed on the spindle box is an electric spindle. The rotating speed of the spindle can be increased remarkably, the load of the spindle can be reduced, the vibration of the spindle can be reduced, the rigidity of the lathe bed can be improved, and accordingly the surface turning quality of the lathe can be improved effectively, the polished surface turning effect can be realized, the production cost of an aluminum alloy hub can be reduced remarkably, and production efficiency can be improved remarkably.
Description
technical field [0001] The invention relates to an electric spindle lathe for wheel hub bright surface turning, which belongs to the field of special machine tools for wheel hub processing. Background technique [0002] With the increase of automobile ownership and the acceleration of replacement, the demand for automobile aluminum alloy wheels continues to increase, and the requirements for the surface quality of the wheels are also getting higher and higher. Some of the inner and outer surfaces have a roughness of 1.6 or even 0.4, which requires lathes Achieve bright surface, even mirror cutting. [0003] The hub processing lathe is a special-purpose machine tool. The larger-diameter hub, plus clamping fixtures, transmission pulleys and other components are all installed on the main shaft, which need to be driven by the main shaft motor to rotate. The increase in the speed of the main shaft is limited, and it is easy to produce main shaft Vibration (also mentioned in the ...
