Technical Field

[0001] The utility model relates to the field of numerical control machining equipment, and particularly relates to an auxiliary workbench for a vertical and horizontal gantry machining center. Background Art

[0002] A gantry machining center refers to a machining center in which the axis of the power head provided on the gantry is perpendicular to the main workbench surface. A transverse power head is provided on one side of the gantry machining center to achieve vertical and horizontal use. By horizontally or longitudinally moving the main workbench and horizontally or vertically moving the power head of the gantry machining center, horizontal machining or vertical machining can be performed on the workpiece mounted on the main workbench. When machining the inclined part on the workpiece by the gantry machining center, it is necessary to adjust the installation angle of the workpiece to achieve. Due to the need for repeated clamping and adjustment, the operation is generally cumbersome and affects the operation efficiency. At present, although there is a public technology of an auxiliary workbench with horizontal rotation for a vertical and horizontal gantry machining center. For example, the utility model patent with the authorization announcement number CN221415739U discloses "An auxiliary workbench for a vertical and horizontal gantry machining center", which describes: "... by setting... a servo motor, a rotating rod, an auxiliary workbench body, a rotating workbench... starting the servo motor in the motor slot, the output end of the servo motor drives the rotating rod to rotate, so that the rotating workbench rotates on the auxiliary workbench body, so that multiple sides of the workpiece on the rotating workbench are machined by the horizontal machining center...". It can be seen from this public technology that the set rotating workbench can only rotate horizontally and can only perform machining at different angles on the circumferential side of the workpiece. However, this auxiliary workbench cannot swing up and down and cannot solve the problem that if there is an inclined part on the top surface of the workpiece that needs to be machined. In view of this, it is necessary to improve the auxiliary workbench so that it can not only rotate horizontally but also swing up and down to meet the need for multi-directional machining of the workpiece, thereby improving the applicable range of the vertical and horizontal gantry machining center and the convenience of operation. This is the problem to be solved in this case. Content of the Utility Model
