in the work table 100 of the present invention, the work table 100 includes a support table 40 and a plurality of turn tables 30, the support table 40 includes a plurality of processing stations, and the plurality of processing stations are provided at intervals; the plurality of turntables 30 are arranged in one-to-one correspondence with the plurality of processing stations, and each turntable 30 is rotatably arranged at a corresponding processing station; the plurality of processing stations are arranged on the supporting table 40, the plurality of rotary tables 30 are arranged on the plurality of processing stations in a one-to-one correspondence manner, and each rotary table 30 can rotate on the corresponding processing station, namely each rotary table 30 can independently run to be matched with a numerical control processing center which is provided with a vertical milling head and a horizontal milling head at the same time, so that the numerical control processing center can simultaneously utilize the vertical milling head and the horizontal milling head to perform type milling and horizontal milling on the workpiece on the corresponding rotary table 30; it can be seen that, compared with the prior art that vertical milling and horizontal milling operations are respectively realized by different numerical control machines, the vertical milling and horizontal milling operations can be simultaneously realized by using the workbench 100, so that the milling efficiency of the workbench 100 is higher, i.e. the workbench 100 can solve the problem of lower milling efficiency in the prior art.
In addition, the supporting table 40 is rotatably provided about a predetermined rotation axis, and the plurality of turntables 30 are arranged about the predetermined rotation axis, that is, when the supporting table 40 rotates, the respective turntables 30 can be driven to rotate synchronously to rotate the turntables 30 carrying the workpiece to be machined to the corresponding positions, so that the vertical milling head or the horizontal milling head can act on the workpiece to be machined.
Since the machine tool of the present invention includes the table 100, the machine tool has at least the same technical effects as the table 100.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
