Embodiment
In order to make technical problem to be solved in the utility model, technical solution and beneficial effect clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
A kind of small-sized gantry machine tool structure, it is as depicted in figs. 1 and 2, described comprising base 2, platform 1, column 3, crossbeam 4
Platform 1 is arranged on the base 2, and the column 3 is arranged on the platform 1, and the crossbeam 4 is arranged at the column 3
Top is simultaneously parallel with the horizontal plane where the platform 1；Wherein, the platform 1, column 3 are marble material and the column 3
For gantry upright post, i.e., marble crossbeam 4 is across above the left and right column of marble gantry upright post 3.The base 2 is adopted
Cylinder iron material, has higher wearability and rigidity, and platform and column use marble material, make platform and Column stability
Height, deformation is small, and then ensures the machining accuracy of lathe.
In order to further enhance the stability of lathe, the crossbeam 4 is the triangular prism that section is in isosceles right triangle, such as
Shown in Fig. 2, the crossbeam includes three faces, the first face of crossbeam 41, the second face of crossbeam 42, the 3rd face 43 of crossbeam, the crossbeam
