[0006] The utility model changes the supporting mode of the stand of the turning and milling combined machining center by setting the slide with the original plane structure as a U shape and adding supporting parts on both sides of the stand, changes the original mode of supporting the stand by the guide rail driven by the lead screw to the mode of embracing the stand by the U-shaped guide rail, changes the supporting point of the stand from the bottom of the stand to both sides of the stand, and sets corresponding supporting seats on both sides of the stand to cooperate with the U-shaped guide rail. The problem that the slide and the guide rail set between the bottom of the stand and the top of the slide in the prior art are difficult to improve the running stability and rigidity of the machine tool is solved.

[0007] Further, in order to improve the stability of the cooperation between the track and the slider, the support part comprises: an installation beam arranged on the top of the slider and covering the top surface and the two side surfaces of the slider; a support plate arranged on the top of the installation beam; and a reinforcing plate perpendicular to the support plate and connecting the top surface of the support plate and the side wall of the column.

[0008] Further, in order to improve the stability of the column during movement and reduce the load of the support part on the track and the slider, the support part is arranged between the support plate and the column along the reinforcing plate in the extension direction of the track.

[0009] Further, in order to ensure the stability of the column during movement driven by the driving device, the bottom of the U-shaped groove is provided with a driving device installation groove in the same vertical position as the axis.

[0010] Further, in order to not change the relative position relationship between the original track and the slider, the top of the support table is provided with a track guide groove connected with the track.

[0011] The beneficial effects of the present application are:

[0012] 1.

[0025] As Figure 1 Fig. 1 illustrates a vertical column mechanism of a turning-milling combined machining center according to the present application. In order to improve the running stability and rigidity of the machine tool, the sliding table (1) originally in a planar structure is set to be U-shaped, and support parts (5) are additionally provided on both sides of the vertical column (2). This design changes the support mode of the vertical column (2) of the turning-milling combined machining center. Originally, the vertical column (2) is moved on the top of the sliding table (1) by driving the guide rail through the lead screw, and now the U-shaped guide rail (i.e. the linear guide rail 3 and the sliding block 4 thereon) supports the vertical column (2) in a clamping manner. The support point is shifted from the bottom of the vertical column (2) to both sides of the vertical column (2), so that the support point is closer to the center of gravity of the vertical column, thereby making the vertical column (2) more stable during movement. At the same time, the provision of the support parts (5) enhances the connection strength between the vertical column (2) and the sliding table (1), thereby improving the overall rigidity and running stability of the machine tool.

[0026] Embodiment 2:

[0027] As Figure 1The application discloses a turning and milling combined machining center column mechanism, in order to optimize the support structure and improve the stability of the column, in order to further improve the stability of the cooperation between the linear rail (3) and the sliding block (4), the support part (5) comprises a mounting cross beam (51) arranged on the top of the sliding block (4), the mounting cross beam (51) covers the top surface and the two side surfaces of the sliding block, and the sliding block (4) is provided with all-round support. A support plate (52) is arranged on the top of the mounting cross beam (51), and a reinforcing plate (53) is perpendicular to the support plate (52) and is connected between the top surface of the support plate (52) and the side wall of the column (2). The three-layer structure design not only enhances the overall strength of the support part, but also makes the column (2) more uniform in stress during movement, and reduces vibration. In addition, the reinforcing plate (53) is arranged at equal intervals between the support plate (52) and the column (2) along the extension direction of the linear rail (3), and the design improves the stability of the column (2) and reduces the load of the support part (5) on the linear rail (3) and the sliding block (4).
