BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a machining device, and more particularly to a wheel machining device that promotes space utilization.
2. Description of Related Art
A wheel lathe is a device for finishing or manufacturing wheel frames. A conventional wheel lathe has a spindle for drilling and milling the wheel frames and a worktable for fixing a wheel frame. The worktable of the conventional wheel lathe can longitudinally and laterally move the wheel frame relative to the spindle to finishing parts of the wheel frame.
However, in order to move the wheel frame, the worktable of the conventional wheel lathe has to be equipped with longitudinal-driving device and lateral-driving device. Size of the worktable is increased, overall occupied space of the wheel lathe is enlarged accordingly. Therefore, space utilization of the conventional wheel lathe is low. In addition, the wheel frame fixed to the worktable of the conventional wheel lathe, is raised up by the longitudinal-driving device and the lateral-driving device and is adjacent to the spindle.
Therefore, the conventional wheel lathe cannot machine a wheel frame with a large width. In order to machine the wheel frame with a large width, a position of the spindle has to be increased.
Consequently, the conventional wheel lathe has low space utilization and is difficult to be laid up, boxed, and shipped.
To overcome the shortcomings, the present invention tends to provide a wheel machining device to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a wheel machining device that promotes space utilization.
A wheel machining device comprises a base, at least one 1 longitudinal-driving set, a movable mount, at least one lateral-driving set, a machining set, and a worktable. Each longitudinal-driving set is mounted to the base. The movable mount is connected with the longitudinal-driving set and driven by that to move longitudinally. The lateral-driving set is mounted to the movable mount. The machining set is connected with the lateral-driving set and driven by that to move laterally. The worktable is adjacent to one of two ends of the base. The at least one longitudinal-driving set and the lateral-driving set are assembled with the base which originally occupies a certain space. Therefore, the space utilization of the present invention is promoted.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
