Description

Technical Field

[0001] This utility model relates to the field of CNC gantry milling machine production and design technology, specifically a dual-spindle CNC gantry milling machine. Background Technology

[0002] Gantry milling machines are high-efficiency, high-precision machine tools widely used in large-scale machining fields. Among them, the twin-spindle CNC gantry milling machine is one of the more common types.

[0003] When machining on a twin-spindle CNC gantry milling machine, there is a situation where the sheet metal needs to be machined on both sides. The usual solution is to flip the sheet metal after rough machining and then perform finish machining. This machining method is time-consuming, affects the overall machining efficiency, and cannot guarantee the positional accuracy after flipping, which affects the accuracy of finish machining, thus having limitations.

[0004] The reason for this problem is that after rough machining, the sheet metal is immediately flipped over to perform more detailed processing on the other side. The flipping process typically involves opening the fixture, lifting and flipping the sheet metal, fixing the fixture, and then machining. This entire flipping and repositioning process is quite time-consuming, lengthening the overall machining cycle. More importantly, during the flipping process, it's difficult to ensure the sheet metal accurately returns to its originally set precise position. This slight positional deviation is amplified in the subsequent finishing stage, directly affecting the final product's machining accuracy and quality. Therefore, this method has limitations and cannot meet the current manufacturing industry's demand for high-efficiency, high-precision machining. Therefore, we propose a dual-spindle CNC gantry milling machine to solve the above problems. Utility Model Content

[0035] In this embodiment, during plate installation, the fastening bolt 324 is unscrewed, and the limiting block 322 is pushed into the positioning groove 321, so that the magnetic block 323 is magnetically connected to the positioning groove 321. At this time, the plate can be hoisted onto the support block 31. After hoisting, the limiting block 322 is grasped and opened to both sides, and the fastening bolt 324 is tightened to make it abut against the plate, thus fixing the plate.
