Description

Technical Field

[0001] The utility model relates to the technical field of vertical machining, in particular to a vertical machining center column. Background Art

[0002] The vertical machining center is a highly automated multifunctional CNC machine tool with a tool magazine and automatic tool changer. The column of the vertical machining center is an important part of the vertical machining center. It sits on the base and supports the spindle head to move up and down in the Z-axis direction. However, after using the current vertical machining center column for a period of time, there will be some slight changes in accuracy, which seriously affects the quality of the workpiece.

[0003] There are many reasons that lead to changes in the accuracy of the column of the vertical machining center, and the installation method of the tool magazine is one of the reasons that lead to changes in the accuracy of the column. In the prior art, the tool magazine is usually hung on the side of the column. After long-term use, due to the weight of the tool magazine, the column will have an unbalanced force problem, which will cause the column to tilt slightly toward the direction of the tool magazine, seriously affecting the machining accuracy. Utility Model Content

[0004] In order to solve the above-mentioned problem, that is, the problem that the accuracy of the column of the current vertical machining center will change, the utility model proposes a vertical machining center column, which includes a column body, and two base parts are installed at the bottom of the column body, the two base parts are symmetrically arranged with respect to the column body, and the two base parts are arranged at equal angles; a mounting part is arranged on the inclined surface of one of the base parts, and the upper surface of the mounting part is arranged horizontally for installing a tool magazine.

[0005] The utility model is further configured as follows: the angle between the two bottom feet is configured to be 120°-150°.

[0006] The utility model is further configured as follows: the angle between the two bottom feet is configured as 150°.

[0007] The utility model is further configured as follows: a connecting boss is arranged on the lower surface of the base portion; and a base mounting plate is also included, and the boss is supported on the base mounting plate.

[0008] The beneficial effects of the utility model are:

[0009] By setting the two bottom feet at equal angles, it is possible to increase the span between the two bottom feet, thereby improving the stability of the column body. By setting the mounting portion on the inclined surface of the bottom foot portion, it is possible to provide a support for the mounting portion. At the same time, since the upper surface of the mounting portion is set horizontally, after the tool magazine is installed, the gravity generated by the weight of the tool magazine will be vertically downward, and then act on the bottom foot, thereby avoiding the suspension force generated by the weight of the tool magazine that will cause the column body to tilt, thereby improving the machining accuracy of the machine tool.

[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] The utility model proposes a vertical machining center column, including a column body 1, the column body 1 is hollow, so as to achieve the purpose of reducing the weight of the casting. Two foot parts 2 are installed at the bottom of the column body 1, the two foot parts 2 are symmetrically arranged about the column body 1, and the two foot parts 2 are arranged at equal angles, that is, the two foot parts 2 are arranged in a "human" shape. A mounting part 21 is integrally arranged on one of the foot parts 2, and the mounting part 21 is arranged on the inclined surface of the foot part 2. The upper surface of the mounting part 21 is horizontally arranged to install a tool magazine. In this way, when the tool magazine is installed on the upper surface of the mounting part 21, the upper surface of the mounting part 21 is horizontally arranged, so the gravity generated by the weight of the tool magazine itself will be vertically downward, so that the gravity of the tool magazine directly acts on the foot part 2.

[0016] The angle between the two bottom feet 2 is set to 120°-150°. In the present application, the angle between the two bottom feet 2 is set to 150°, which can not only increase the span between the two bottom feet 2, but also will not affect the normal use of the machining center.

[0017] It should be noted that the distance between the two foot parts 2 is arbitrarily selected between 120° and 150°, which is selected according to the environmental conditions of the vertical machining center.

[0018] A boss 22 is integrally provided on the lower surface of the foot portion 2. A foot mounting plate 3 is also included, and the boss 22 is supported on the foot mounting plate 3. By providing the boss 22, the contact area between the foot portion 2 and the foot mounting plate 3 can be reduced. Compared with the large-area contact between the foot portion 2 and the foot mounting plate 3 in the prior art, it will undoubtedly increase the difficulty of processing because the two have a high requirement for flatness when in contact. By contacting the foot mounting plate 3 through the boss 22, the difficulty of processing is reduced while the contact area is small.

[0019] In summary, the utility model can increase the span between the two bottom feet 2 and thus improve the stability of the column body 1 by setting the two bottom feet 2 at equal angles, and setting the mounting portion 21 on the inclined surface of the bottom foot 2 can provide a support for the mounting portion 21. At the same time, since the upper surface of the mounting portion 21 is set horizontally, after the tool magazine is installed, the gravity generated by the weight of the tool magazine will be vertically downward, and then act on the bottom foot 2, avoiding the hanging force generated by the weight of the tool magazine that will cause the column body 1 to tilt, thereby improving the processing accuracy of the machine tool.
