Description

TECHNICAL FIELD

[0001] The utility model belongs to machining center technical field, especially relate to a vertical and horizontal common column type machining center. BACKGROUND

[0002] The machining center is divided into vertical machining center and horizontal machining center according to the relative position of spindle and worktable. Taking the standard six-face cube workpiece as an example, the spindle of vertical machining center is from top to bottom, which is used for processing the top surface of workpiece, and the horizontal machining center is used for processing the side surface of workpiece. When the horizontal machining center is matched with rotary table, the four side surfaces of workpiece can be processed. When clamping the workpiece to the machining center, all positioning references need to be calibrated, and there is a certain error in calibration, so multiple clamping of workpiece will lead to the reduction of machining accuracy.

[0003] For example, the Chinese patent document with publication number CN110769974A discloses a simple structure pentahedron machining center machine tool, which comprises a gantry machining center and a group of horizontal machining centers arranged on the side of the gantry machining center. The gantry machining center comprises a group of vertical machining centers, and the base of the gantry machining center is provided with an X-direction guide rail, and a longitudinal workbench is slidably installed on the X-direction guide rail. The longitudinal workbench is provided with a rotary workbench capable of rotating 360 degrees. The horizontal machining center comprises a horizontal base, a Z-direction guide rail, a horizontal column perpendicular to the horizontal base, a first sliding rail arranged on the horizontal column, a transmission device and a horizontal spindle box. The transmission device drives the horizontal spindle box to move up and down on the first sliding rail and drives the horizontal column to move reciprocatingly and linearly along the Z-direction guide rail. The vertical machining center comprises a Y-direction guide rail arranged on the cross beam of the gantry frame, a vertical column slidably installed on the Y-direction guide rail, a second sliding rail arranged on the vertical column, a transmission device and a vertical spindle box. The transmission device drives the vertical spindle box to move up and down on the second sliding rail and drives the vertical spindle to move reciprocatingly and linearly along the Y-direction guide rail.

[0004] In the technical scheme of the above patent document, the workpiece is clamped on the rotary workbench once, and the machining process of the top surface and the four side surfaces of the workpiece is completed, which improves the machining efficiency and avoids the reduction of accuracy caused by multiple clamping of workpiece. However, the use of two column structures, two sets of lifting devices and multiple sliding rail structures will increase the manufacturing cost and use cost of the machining center, and occupy a large space area. The rotary workbench moves on the X-direction guide rail, the transmission device of the horizontal machining center drives the horizontal spindle box to move up and down and move back and forth, and the transmission device of the vertical machining center drives the horizontal spindle box to move up and down and move left and right, so that the control process of movement becomes complex and the machining accuracy is also reduced.

[0038] Further, the end side of the vertical spindle 400 and the horizontal spindle 500 is further provided with a protection device 600, which is used for shielding the spindle hole 611. Specifically, the protection device 600 shields the spindle hole 611, so as to protect the non-working spindle, and avoid the waste generated by machining of other spindles from entering the spindle hole 611, and affecting the assembly and use of the subsequent cutting tool.

[0039] Further, the protection device 600 comprises a sleeve 610, a baffle 620 and a moving driving member 630. The sleeve 610 is sleeved outside the vertical spindle 400 and the horizontal spindle 500. The end of the sleeve 610 is provided with the spindle hole 611, which is used for avoiding the connection of the vertical cutting tool and the vertical spindle 400 and / or avoiding the connection of the horizontal cutting tool and the horizontal spindle 500. The side of the spindle hole 611 is provided with a guide member 640. The baffle 620 is slidably connected with the guide member 640. The moving driving member 630 is connected with the baffle 620, and is used for pushing the baffle 620 to cover the spindle hole 611. Specifically, when the vertical spindle 400 is machining a workpiece, and the horizontal spindle 500 is in a non-working state, the protection device of the horizontal spindle 500 is in a closed strip. The moving driving member 630 drives the baffle 620 to cover the spindle hole 611, so that the horizontal spindle 500 is not connected with the cutting tool. The sleeve 610 and the baffle 620 fully surround the horizontal spindle 500, and protect the spindle hole 611 from being invaded by waste and impurities, and play a good protection role on the horizontal spindle 500.
