[0028] Refer to Figure 3-6As shown in the figure, as an embodiment of the present utility model, a new type of column is provided, specifically a new type of column for a cradle five-axis machining center, including a column body 1. The top side of the column body 1 is used for the longitudinal slide 9 to slide along the first direction thereon. At least one end of the column body 1 corresponding to the first direction is provided with an inclined surface 2, and the inclined direction of the inclined surface 2 is gradually inclined outward from top to bottom. Specifically, the first direction is the front-rear direction, that is, the front-rear direction is the Y-axis direction, the left-right direction is the X-axis direction, and the up-down direction is the Z-axis direction. The front end of the longitudinal slide 9 protrudes from the column body 1 to be suspended in front of the top side of the column body 1. The spindle box 10 slides up and down at the front end of the longitudinal slide 9. Correspondingly, the inclined surface 2 is located at the front end of the column body 1. The structure of the column of this technical solution has stronger structural rigidity and better anti-tilting performance. When the longitudinal slide 9 slides forward to increase the overhang of the longitudinal slide 9 and the spindle box 10, it can effectively relieve the drooping of the spindle box 10, ensure stable support, and thus ensure machining accuracy. Under the condition that the weights are basically the same, the anti-tilting rigidity value of the column with an inclined angle of the present utility model in the Y-axis direction is increased by 15% compared with the existing column with a vertical angle, and the column with an inclined angle has a larger contact area, making the column more rigid while dispersing the force on the base 11 and improving the overall rigidity and stability of the machining center.
[0029] In this embodiment, the column body 1 is of a hexahedron structure, and an installation hole 3 running through the front and rear is provided inside it. The installation hole 3 is used for installing the motor base 12 therein. A hollow partition cavity is formed around the installation hole 3 inside the column body 1. The partition cavity includes a first partition cavity 4 and a second partition cavity 5. There are two first partition cavities 4, and the two first partition cavities 4 are symmetrically arranged on the left and right sides of the installation hole 3 respectively. There are multiple second partition cavities 5, and the multiple second partition cavities 5 are arranged in a matrix above the installation hole 3, so that the left and right sides and the upper part of the column body 1 corresponding to the installation hole 3 are of a two-layer plate structure, enhancing the structural rigidity of the column body 1 and preventing the column body 1 from sagging in the middle and deforming by spreading to both sides.
[0030] Of course, in other cases, the inclined surface can also be adjusted correspondingly according to the cantilever position of the slide and set at the rear end or the left and right ends of the column body.
[0031] In this embodiment, the inner wall of the first partition cavity 4 forms a rib 6, and the rib 6 is a grid-shaped rib, so as to ensure the overall structural strength of the column.
[0032] In this embodiment, a through hole 7 communicating with the installation hole 3 is opened on the bottom side wall of the second partition cavity 5 to meet the lightweight requirement.
[0033] Refer to Figure 7 And 8As shown in the figure, the present utility model also provides a cradle five-axis machining center, which includes the novel column described in the above embodiment, as well as a base 11 and a motor base 12. A transverse slide 8 is slidably arranged left and right on the top side of the column body 1. A longitudinal slide 9 is slidably arranged front and back on the top side of the transverse slide 8. The front end of the longitudinal slide 9 protrudes out of the column body 1 to be suspended in front of the top side of the column body 1. The spindle box 10 is slidably arranged up and down at the front end of the longitudinal slide 9. The column body 1 is installed above the base 11, and the motor base 12 is installed in the installation hole 3. A turntable 13 is installed on one side of the motor base 12. The structure of the column of the cradle five-axis machining center of the present utility model has stronger rigidity and better anti-tilting performance. When the longitudinal slide 9 slides forward to increase the overhang of the longitudinal slide 9 and the spindle box 10, it can effectively relieve the drooping of the spindle box 10 and ensure stable support, thereby ensuring machining accuracy. The anti-tilting rigidity value of the column of this cradle five-axis machining center has increased by 15%, and the column with an inclined angle has a larger contact surface area, making the column more rigid while dispersing the force on the base 11 and improving the overall rigidity and stability of the machining center.
