Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a gantry-type CNC machining machine tool. Background Technology

[0002] CNC machining tools are traditional machine tools with an added numerical control system. This system can interpret instructions written in G-code or other symbolic languages ​​and convert them into electrical signals to control the movement and machining process of the machine tool. The operator only needs to input the instruction program into the computer and load the required tools into the machine tool, and the rest of the work can be completed automatically by the computer.

[0003] A gantry CNC machining center, as described in reference announcement number CN211305509U, includes a frame. A first translation mechanism is mounted on the frame along the Y-axis, and a worktable is mounted on the first translation mechanism. A second translation mechanism is mounted above the worktable along the X-axis, and a rotation mechanism is mounted on the second translation mechanism. The rotation mechanism includes a spindle box, in which a spindle is inserted along the Y-axis. The rear end of the spindle is connected to a reducer, which cooperates with a third motor. The front end of the spindle is connected to a rotary seat, and a lifting mechanism is mounted on the rotary seat along the Z-axis. A tool shaft assembly is mounted on the lifting mechanism. By rotating and adjusting the tool shaft assembly through the rotation mechanism, multi-angle machining can be achieved, fully meeting the multi-faceted machining requirements of parts. As can be seen from the above, although this CNC machining center can be well applied, it is usually not convenient to stably place multiple workpieces on the machining platform, thus making it difficult to stably and quickly process the workpieces, which often troubles users.

[0012] (1) By placing the workpiece to be processed on the top of the base and attaching it to the inner wall of the first clamping plate, and then turning the threaded rod, the threaded rod rotates and slides inside the base, and the threaded rod drives the second clamping plate to move and attach to the outer wall of the other side of the workpiece. The second clamping plate, in conjunction with the first clamping plate, can clamp and fix the workpiece on the top of the base. Since there are three bases, three workpieces can be placed on the upper part of the workpiece placement table, which makes it easy to process the workpiece in multiple stations in sequence, thereby improving the processing efficiency of the CNC machine tool and ensuring the processing accuracy of the workpiece.

[0013] (2) The first motor drives the first lead screw to rotate, so that the nut pair on the outer wall of the first lead screw drives the lifting body to move laterally. Then, the second motor drives the second lead screw to rotate, so that the nut pair on the outer wall of the second lead screw drives the lifting frame to move up and down. When the third motor drives the third lead screw to rotate, the nut pair on the outer wall of the third lead screw will drive the placement table to move back and forth, thereby adjusting the position of the milling cutter up, down, left and right, and moving the workpiece placed above the placement table to below the milling cutter, thereby improving the convenience of using the CNC machining tool.

[0014] (3) The exhaust fan is driven by the second rotary drive to draw the dust-laden air generated during the workpiece processing into the purification box through the exhaust hood. The dust-laden air is filtered by the filter screen built into the purification box, and the filtered air is discharged through the exhaust port to achieve the purpose of purifying the environment around the machine tool, thereby improving the environmental protection of the CNC machining machine tool.
