Problems solved by technology
[0002] The existing gantry CNC milling machine has only one spindle to drive the tool to process. If it is necessary to add another spindle to work, it can only add another gantry and other related spindle installation devices, which will cause inconvenient processing, and in limited working space Under these conditions, it is unreasonable to add other processing devices, and it will increase the safety of the working environment and various related costs
If a double-drive design is adopted, that is, one screw is equipped with two spindles, processing can be carried out at the same time, and the efficiency is improved. However, the traditional moving device adopts the method that the screw rotates and the spindle nut moves along the screw, and the two spindles can only be driven at the same time. work, and the moving direction is the same, the processing method is relatively simple, and the improvement of processing efficiency is also greatly restricted

The invention discloses a double independent driving gantry numerically controlled milling machine. The milling machine comprises a first supporting column and a second supporting column which are fixed to the left side and the right side of a workbench body correspondingly, and a cross beam connected between the two supporting columns. The cross beam is fixedly connected with a first Z-axis device connected with a first motor and a second Z-axis device connected with a second motor, and a first lead screw. The first lead screw is in engaged connection with a first lead screw nut and a secondlead screw nut. The first lead screw nut is provided with first lead screw nut external wheel teeth connected with the first motor. The second lead screw nut is provided with second lead screw nut external wheel teeth connected with the second motor. According to the milling machine, the lead screw nuts are adopted and connected with the motors in all spindles correspondingly, the lead screw doesnot move while the lead screw nuts rotate, the spindles move on the lead screws, all the spindles are independently driven and controlled, the multiple spindles can be used for machining simultaneously, the machining efficiency is substantially improved, and the production cost is lowered.
