Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tools, specifically to a multi-channel, multi-spindle drilling and tapping machine tool. Background Technology

[0002] Currently, vertical CNC machine tools generally consist of a base, column, spindle box, and tool magazine. The spindle box is equipped with a tool magazine and is mounted in front of the column via a mounting base. The base has a workpiece placement position, and the tools in the tool magazine machine the parts placed in the workpiece placement position. Existing vertical CNC machine tools generally use single-station machining, resulting in low machining efficiency. To address the above problems, publication number CN202111504473.1 discloses a multi-spindle CNC machine tool, including a base with a Y-axis moving device, an X-axis moving device on the Y-axis moving device, a worktable on the X-axis moving device, and a column behind the worktable. The column is mounted on the base, and at least two spindle boxes are slidably mounted on the column, arranged side by side. Each spindle box has a corresponding tool magazine. Each spindle box includes a first mounting base and a spindle mounting part connected to the first mounting base. The spindle mounting part has mounting holes for mounting the spindle, and the center of each mounting hole is offset from the center plane of the first mounting base in a direction away from the other mounting hole. The multi-spindle CNC machine tool proposed in this invention shortens the width and weight of the column, saving costs. However, this CNC machine tool has the following problems: 1. In existing machine tools, the X and Y axes are both set on the worktable, working with the column and spindle box to achieve multi-axis motion and process the workpiece. However, since the X and Y axes are both set on the worktable, this method requires the workpiece to be moved through the worktable, making it impossible to perform independent processing and independent compensation processing of multiple workpieces, thus affecting processing efficiency; 2. In existing machine tools, the tool magazine is set above the spindle. When a tool change is required, the spindle needs to be raised to a certain height before the tool change can be performed. The tool change process is cumbersome, lacks continuity, and takes a long time, affecting subsequent processing efficiency and making it inconvenient for operators to maintain or replace the tools in the tool magazine.
