Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wheel lathe that corrects a wheel that has been worn or deformed by forming or running a wheel of a railway vehicle or the like.
[0002]
[Prior art and problems to be solved by the invention]
A wheel lathe is generally configured as follows.
[0003]
The wheel removed from the vehicle body rolls on a rail provided as a conveyance guide unit and is conveyed to the cutting device, and the wheel is stopped at the main shaft position provided rotatably, and then the wheel is stopped by the lifter device. The mounting portion for raising and lowering the wheel at the position is raised, and the wheel is raised to a height at which the wheel shaft coincides with the main shaft.
[0004]
Then, the raised wheel is chucked and fixed to a chuck portion provided on the main shaft, and after the wheel is fixed to the main shaft, the mounting portion is lowered and retracted by the lifter device.
[0005]
After the setting of the wheel to the main shaft is completed, the main shaft is rotated to rotate the wheel, and the cutting tool provided in the cutting apparatus is NC controlled to cut the wheel.
[0006]
After the processing is completed, the wheel is supported on the raised mounting portion, and then the chuck by the chuck portion is removed and lowered to roll out again along the conveyance guide portion.
[0007]
However, wheels that perform such cutting work are often accompanied by wheel accessories such as a gear box. In this case, the left and right wheels of the wheel shaft roll on the conveyance guides (rails) during conveyance. The wheel accessory must be dragged and transported.
[0008]
However, if dragged as it is, not only will the transfer be smooth, but it may damage the wheel accessories.
[0009]
For this reason, it is not easy to remove the wheel appendages and reassemble them after finishing the machining.To avoid this drag transport, roll the wheels along the rails while hanging the vehicle appendages with a crane or the like. ing. Therefore, it is the present situation that the wheel appendages are transported while being suspended by a crane during transportation, and automation cannot be achieved.
[0010]
In addition, there are some casters that are attached to the wheel grounding contact position of the wheel accessories, or casters that have been installed in advance in consideration of dragging by this wheel lathe, but it is troublesome to attach these casters sequentially. However, there are many that have not been established.
[0011]
On the other hand, when the wheel is lifted during the cutting process, the wheel appendage is lifted while being tilted, and when the wheel is rotated while processing is performed, the wheel appendage may oscillate and high-precision machining may not be performed.
[0012]
The present invention solves such a problem, and even if there is an accessory on the wheel, it is not necessary to carry the wheel accessory while suspending it with a crane, and automation is easily achieved, and a caster is attached. It is not necessary and can be transported smoothly without dragging with rolling rolling of the wheel, and even if a caster is already installed, it can be transported without any problem, and even if there is no wheel accessory, it can be handled without any problem Another object of the present invention is to provide a revolutionary wheel lathe capable of cutting a wheel without hindering the wheel appendage from being suspended during processing.
